The One-Week Hijacking of Perl.com - Explained
by Peter Reutemann 07 Mar '21

07 Mar '21

'"For a week we lost control of the Perl.com domain," a long-running site offering news and articles about the programming language, writes the site's senior editor, brian d foy. "Now that the incident has died down, we can explain some of what happened and how we handled it." This incident only affected the domain ownership of Perl.com and there was no other compromise of community resources. This website was still there, but DNS was handing out different IP numbers... Recovering the domain wasn't the end of the response though. While the domain was compromised, various security products had blacklisted Perl.com and some DNS servers had sinkholed it. We figured that would naturally work itself out, so we didn't immediately celebrate the return of Perl.com. We wanted it to be back for everyone. And, I think we're fully back. However, if you have problems with the domain, please raise an issue so we at least know it's not working for part of the internet. What we think happened This part veers into some speculation, and Perl.com wasn't the only victim. We think that there was a social engineering attack on Network Solutions, including phony documents and so on. There's no reason for Network Solutions to reveal anything to me (again, I'm not the injured party), but I did talk to other domain owners involved and this is the basic scheme they reported. John Berryhill provided some forensic work in Twitter that showed the compromise actually happened in September. The domain was transferred to the BizCN registrar in December, but the nameservers were not changed. The domain was transferred again in January to another registrar, Key Systems, GmbH. This latency period avoids immediate detection, and bouncing the domain through a couple registrars makes the recovery much harder... Once transferred to Key Systems in late January, the new, fraudulent registrant listed the domain (along with others), on Afternic (a domain marketplace). If you had $190,000, you could have bought Perl.com. This was quickly de-listed after the The Register made inquiries. "I think we were very fortunate here and that many people with a soft spot in their hearts for Perl did a lot of good work for us," the article notes. "All sides understood that Perl.com belonged to Tom and it was a simple matter of work to resolve it. A relatively unknown domain name might not fare as well in proving they own it..." But again, the incident ended happily, foy writes, and "The Perl.com domain is back in the hands of Tom Christiansen and we're working on the various security updates so this doesn't happen again. The website is back to how it was and slightly shinier for the help we received."' -- source: https://developers.slashdot.org/story/21/03/06/0510239 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

CentOS Is Gone -- But RHEL Is Now Free For Up To 16 Production Servers
by Peter Reutemann 06 Mar '21

06 Mar '21

'Ars Technica: Last month, Red Hat caused a lot of consternation in the enthusiast and small business Linux world when it announced the discontinuation of CentOS Linux. Long-standing tradition -- and ambiguity in Red Hat's posted terms -- led users to believe that CentOS 8 would be available until 2029, just like the RHEL 8 it was based on. Red Hat's early termination of CentOS 8 in 2021 cut eight of those 10 years away, leaving thousands of users stranded. Red Hat's December announcement of CentOS Stream -- which it initially billed as a "replacement" for CentOS Linux -- left many users confused about its role in the updated Red Hat ecosystem. As of February 1, 2021, Red Hat will make RHEL available at no cost for small-production workloads -- with "small" defined as 16 systems or fewer. This access to no-cost production RHEL is by way of the newly expanded Red Hat Developer Subscription program, and it comes with no strings -- in Red Hat's words, "this isn't a sales program, and no sales representative will follow up." Red Hat is also expanding the availability of developer subscriptions to teams, as well as individual users. Moving forward, subscribing RHEL customers can add entire dev teams to the developer subscription program at no cost. This allows the entire team to use Red Hat Cloud Access for simplified deployment and maintenance of RHEL on well-known cloud providers, including AWS, Google Cloud, and Microsoft Azure.' -- source: https://linux.slashdot.org/story/21/01/20/2016202 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Torvalds warns the world: Don’t use the Linux 5.12-rc1 kernel
by Peter Reutemann 06 Mar '21

06 Mar '21

'In a message to the Linux Kernel Mailing List yesterday, founding developer Linus Torvalds warned the world not to use the 5.12-rc1 kernel in his public git tree. Hey peeps - some of you may have already noticed that in my public git tree, the "v5.12-rc1" tag has magically been renamed to "v5.12-rc1-dontuse". It's still the same object, it still says "v5.12-rc1" internally and it is still is signed by me, but the user-visible name of the tag has changed. As it turns out, when Linus Torvalds flags some code dontuse, he really means it—the problem with this 5.12 release candidate broke swapfile handling in a very unpleasant way. Specifically, the updated code would lose the proper offset pointing to the beginning of the swapfile. Again, in Torvalds' own words, "swapping still happened, but it happened to the wrong part of the filesystem, with the obvious catastrophic end results."' -- source: https://arstechnica.com/gadgets/2021/03/psa-linux-folks-stay-away-from-the-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Windows.com Bitsquatting Hack Can Wreak 'Unknown Havoc' On PCs
by Peter Reutemann 05 Mar '21

05 Mar '21

'Ars Technica: Bitflips are events that cause individual bits stored in an electronic device to flip, turning a 0 to a 1 or vice versa. Cosmic radiation and fluctuations in power or temperature are the most common naturally occurring causes. Research from 2010 estimated that a computer with 4GB of commodity RAM has a 96 percent chance of experiencing a bitflip within three days. An independent researcher recently demonstrated how bitflips can come back to bite Windows users when their PCs reach out to Microsoft's windows.com domain. Windows devices do this regularly to perform actions like making sure the time shown in the computer clock is accurate, connecting to Microsoft's cloud-based services, and recovering from crashes. Remy, as the researcher asked to be referred to, mapped the 32 valid domain names that were one bitflip away from windows.com. Of the 32 bit-flipped values that were valid domain names, Remy found that 14 of them were still available for purchase. This was surprising because Microsoft and other companies normally buy these types of one-off domains to protect customers against phishing attacks. He bought them for $126 and set out to see what would happen. Over the course of two weeks, Remy's server received 199,180 connections from 626 unique IP addresses that were trying to contact ntp.windows.com. By default, Windows machines will connect to this domain once per week to check that the time shown on the device clock is correct. What the researcher found next was even more surprising. "The NTP client for windows OS has no inherent verification of authenticity, so there is nothing stopping a malicious person from telling all these computers that it's after 03:14:07 on Tuesday, 19 January 2038 and wreaking unknown havoc as the memory storing the signed 32-bit integer for time overflows," he wrote in a post summarizing his findings. "As it turns out though, for ~30% of these computers doing that would make little to no difference at all to those users because their clock is already broken."' -- source: https://tech.slashdot.org/story/21/03/04/2152239 I wonder whether anyone has tested apt-get in regards to this...

US Issues Warning After Microsoft Says China Hacked Its Mail Server Program
by Peter Reutemann 05 Mar '21

05 Mar '21

'NBC News: The U.S. has issued an emergency warning after Microsoft said it caught China hacking into its mail and calendar server program, called Exchange. The perpetrator, Microsoft said in a blog post, is a hacker group that the company has "high confidence" is working for the Chinese government and primarily spies on American targets. The latest software update for Exchange blocks the hackers, prompting the U.S. Cybersecurity and Infrastructure Security Agency to issue a rare emergency directive that requires all government networks do so. CISA, the U.S.'s primary defensive cybersecurity agency, rarely exercises its authority to demand the entire U.S. government take protective steps to protect its cybersecurity. The move was necessary, the agency announced, because the Exchange hackers are able "to gain persistent system access." All government agencies have until noon Friday to download the latest software update. In a separate blog post, Microsoft Vice President Tom Burt wrote that the hackers have recently spied on a wide range of American targets, including disease researchers, law firms and defense contractors. There was no immediate indication that the hack led to significant exploitation of U.S. government computer networks. But the announcement marks the second instance in recent months that the U.S. scrambled to address a widespread hacking campaign believed be the work of foreign government spies.' -- source: https://it.slashdot.org/story/21/03/04/022226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Google Chrome releases will soon arrive more frequently than ever. >From a report: In an announcement today, Google said it is updating the Chrome release schedule for the first time in over a decade. For a cool 10+ years now, Chrome stable releases have shipped every 6 weeks with new features, security fixes, etc. With improvements to testing and release processes, Google has realized that it can shorten the release cycle and will do so in Q3 of this year. Starting with Chrome 94, Google will move to a 4-week milestone release cycle. Freaked out at the possibility that Google might break features, remove things you like, or cause other issues with so many releases? Don't worry, Google is also introducing an Extended Stable release that will see milestone updates every 8 weeks.

Privacy-first Browser Brave Now Has Its Own Google Search Rival
by Peter Reutemann 04 Mar '21

04 Mar '21

'Two years after publicly launching a privacy-focussed browser, Brave, founded by former Mozilla executive Brendan Eich, is taking on Google's search business, too. From a report: The announcement of Brave Search puts the upstart in the rare position of taking on both Google's browser and search dominance. Eich says that Brave Search, which has opened a waitlist and will launch in the first half of this year, won't track or profile people who use it. "Brave already has a default anonymous user model with no data collection at all," he says adding this will continue in its search engine. No IP addresses will be collected and the company is exploring how it can create both a paid, ad-free search engine and one that comes with ads. But building a search engine isn't straightforward. [...] Eich says Brave isn't starting its search engine or index from scratch and won't be using indexes from Bing or other tech firms. Instead Brave has purchased Tailcat, an offshoot of German search engine Cliqz, which was owned by Hubert Burda Media and closed down last year. The purchase includes an index of the web that's been created by Tailcat and the technology that powers it. Eich says that some users will be given the ability to opt-in to anonymous data collection to help fine-tune search results. "What Tailcat does is it looks at a query log and a click log anonymously," Eich says. "These allow it to build an index, which Tailcat has done and already did at Cliqz, and it's getting bigger." He admits that the index will not be anywhere near as deep as Google's but that the top results it surfaces are largely the same.' -- source: https://search.slashdot.org/story/21/03/03/1643231 Interesting that they didn't simply use DuckDuckGo...

Microsoft Launches Power Fx, a New Open Source Low-Code Language
by Peter Reutemann 03 Mar '21

03 Mar '21

'Microsoft today announced Power Fx, a new low-code language that "will become the standard for writing logic customization across Microsoft's own low-code Power Platform," reports TechCrunch. "[S]ince the company is open-sourcing the language, Microsoft also hopes others will implement it as well and that it will become the de facto standard for these kinds of use cases." From the report: Microsoft says the language was developed by a team led by Vijay Mital, Robin Abraham, Shon Katzenberger and Darryl Rubin. Beyond Excel, the team also took inspiration from tools and languages like Pascal, Mathematica and Miranda, a functional programming language developed in the 1980s. Microsoft plans to bring Power Fx to all of its low-code platforms, but given the focus on community, it'll start making appearances in Power Automate, Power Virtual Agents and elsewhere soon. But the team clearly hopes that others will adopt it as well. Low-code developers will see it pop up in the formula bars of products like Power Apps Studio, but more sophisticated users will also be able to use it to go to Visual Studio Code and build more complex applications with it. As the team noted, it focused on not just making the language Excel-like but also having it behave like Excel -- or like a REPL, for you high-code programmers out there. That means formulas are declarative and instantly recalculate as developers update their code.

Google-free /e/ OS is now selling preloaded phones in the US, starting at $380

'/e/ OS, the "open-source, pro-privacy, and fully degoogled" fork of Android, is coming to Canada and the USA. Of course, you've always been able to download the software in any region, but now (as first spotted by It's Foss News) the e Foundation will start selling preloaded phones in North America. Previously, /e/ only did business in Europe. Like normal, the e Foundation's smartphone strategy is to sell refurbished Samsung devices with /e/ preloaded. In the US, there are only two phones right now: the Galaxy S9 for $379.99 or a Galaxy S9+ for $429.99. North Americans still have reason to be jealous of Europe, where you can get /e/ preloaded on a Fairphone, which is also Europe-exclusive. These Samsung phones are used devices, but the site says the devices have "been checked and reconditioned to be fully working at our partner's facilities." The phones have a one-year warranty and are described as "Good-as-New" with "no surprises." An /e/ device means you'll be getting a fork of Android 10, and for ongoing support, the e Foundation says, "We aim to support with at least 3 years of software updates and security patches."' -- source: https://arstechnica.com/gadgets/2021/03/google-free-e-os-is-now-selling-pre… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linus Torvalds Went Six Days Without Electricity, Swears Smaller 5.12 Kernel Is Co-Incidental
by Peter Reutemann 03 Mar '21

03 Mar '21

'Linux overlord Linus Torvalds has revealed that inclement weather in the USA meant he recently endured six electricity-free days in his Portland, Oregon, home during which he was unable to tend to the kernel. As a result he therefore pondered adding an extra week to the merge window for version 5.12 of the Linux kernel. The Register reports: "As you can tell, I didn't do that," he said in his State of The Kernel update that announced release candidate one of the new kernel cut. "To a large part because people were actually very good about sending in their pull requests, so by the time I finally got power back, everything was nicely lined up and I got things merged up ok." It wasn't just penguinistas behaving well that helped. Torvalds said this version of the kernel has received around 10,000 commits. That's rather fewer than the 12,000 or 13,000 he usually sees. In case anyone was inconvenienced by blackout-induced inability to merge, Torvalds said he's open to help any kernel devs for whom his unavailability caused problems but is not open to all late pulls. Torvalds rated the new release as offering "a fair amount of historical cleanup" on account of "removing the legacy OPROFILE support (the user tools have been using the "perf" interface for years), and removing several legacy SoC platforms and various drivers that no longer make any sense." Among the big inclusions in 5.12 are Clang Link-Time Optimizations, which make for better compiler performance, and support for Intel's eASIC NX5 silicon that aims to offer an alternative to FPGAs in edge and cloud applications. Qualcomm's Snapdragon 888 5G SoC also gains support.

Go Malware is Now Common, Having Been Adopted by Both APTs and E-crime Groups
by Peter Reutemann 02 Mar '21

02 Mar '21

'The number of malware strains coded in the Go programming language has seen a sharp increase of around 2,000% over the last few years, since 2017, cybersecurity firm Intezer said in a report published recently. From a report: The company's findings highlight and confirm a general trend in the malware ecosystem, where malware authors have slowly moved away from C and C++ to Go, a programming language developed and launched by Google in 2007. While the first Go-based malware was detected in 2012, it took, however, a few years for Golang to catch on with the malware scene. "Before 2019, spotting malware written in Go was more a rare occurrence and during 2019 it became a daily occurrence," Intezer said in its report. But in the new report, Golang (as it's often also referred to instead of Go) has broken through and has been widely adopted. It is used by nation-state hacking groups (also known as APTs), cybercrime operators, and even security teams alike, who often used it to create penetration-testing toolkits.' -- source: https://it.slashdot.org/story/21/03/01/1545257 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

First Fully Weaponized Spectre Exploit Discovered Online
by Peter Reutemann 02 Mar '21

02 Mar '21

'Catalin Cimpanu, reporting for The Record: A fully weaponized exploit for the Spectre CPU vulnerability was uploaded on the malware-scanning website VirusTotal last month, marking the first time a working exploit capable of doing actual damage has entered the public domain. The exploit was discovered by French security researcher Julien Voisin. It targets Spectre, a major vulnerability that was disclosed in January 2018. [...] The vulnerability, which won a Pwnie Award in 2018 for one of the best security bug discoveries of the year, was considered a milestone moment in the evolution and history of the modern CPU. Its discovery, along with the Meltdown bug, effectively forced CPU vendors to rethink their approach to designing processors, making it clear that they cannot focus on performance alone, to the detriment of data security. Software patches were released at the time, but the Meltdown and Spectre disclosures forced Intel to rethink its entire approach to CPU designs going forward. At the time, the teams behind the Meltdown and Spectre bugs published their work in the form of research papers and some trivial proof-of-concept code to prove their attacks. Shortly after the Meltdown and Spectre publications, experts at AV-TEST, Fortinet, and Minerva Labs spotted a spike in VirusTotal uploads for both CPU bugs. While initially there was a fear that malware authors might be experimenting with the two bugs as a way to steal data from targeted systems, the exploits were classified as harmless variations of the public PoC code published by the Meltdown and Spectre researchers and no evidence was found of in-the-wild attacks. But today, Voisin said he discovered new Spectre exploits -- one for Windows and one for Linux -- different from the ones before. In particular, Voisin said he found a Linux Spectre exploit capable of dumping the contents of /etc/shadow, a Linux file that stores details on OS user accounts.' -- source: https://it.slashdot.org/story/21/03/01/1851240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Mint Developers Will Force Updates on Users Like Microsoft Does with Windows 10
by Peter Reutemann 02 Mar '21

02 Mar '21

'Last month, the Linux Mint team published a post on the organization's official blog about the importance of installing security updates on machines running the Linux distribution. The essence of the post was that a sizeable number of Linux Mint devices was running outdated applications, packages or even an outdated version of the operating system itself. A sizeable number of devices run on Linux Mint 17.x, according to the blog post, a version of Linux Mint that reached end of support in April 2019. A new blog post, published yesterday, provides information on how the team plans to reduce the update reluctance of Linux Mint users. Next to showing reminders to users, Linux Mint's Update Manager may enforce some of the updates according to the blog post. "In some cases the Update Manager will be able to remind you to apply updates. In a few of them it might even insist." Upcoming versions will provide information on the implementation, how the "insisting" part may look like, and whether the installation of updates will be enforced. All of this boils down to a single question: how far should operating system developers go when it comes to updates? BetaNews adds: "And now, it seems the Linux Mint developers are taking a page out of Microsoft's playbook by planning to force some updates on its users. Yes, folks, Linux Mint is becoming more like Windows 10."' -- source: https://linux.slashdot.org/story/21/03/01/2032216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Exploring the Open Source That Really Goes Into a RISC-V Chip

Finally we might be about to see open-source from the silicon to the user interface, or so goes the optimistic promise. In fact the real story is considerably more complex than that, and it's a topic [Andreas Speiss] explores in a video that looks at the issue with a wide lens... nickwinlund77 writes: The YouTube video starts out with a good general history of competition between large businesses over architectures and embracing the standards for tech which many of us have depended on throughout the years. The video then gets into the technical specifics of the ESP32-C3. Hackaday adds: His conclusion is that while a truly open-source RISC-V chip is entirely possible (as demonstrated with a cameo Superconference badge appearance), the importance of the RISC-V ISA is in its likely emergence as a heavyweight counterbalance to ARM's dominance in the sector.

Red Hat Introduces Free RHEL for Open-Source Organizations
by Peter Reutemann 01 Mar '21

01 Mar '21

'ZDNet brings an update about the future of Red Hat Enterprise Linux: When Red Hat, CentOS's Linux parent company, announced it was "shifting focus from CentOS Linux, the rebuild of Red Hat Enterprise Linux (RHEL), to CentOS Stream," CentOS users were not happy. Now, in an effort to mollify them and to keep its promise to open-source organizations, Red Hat is introducing a new, free RHEL for Open Source Infrastructure. If your non-profit organization, project, standard body, or foundation is "engaged with open source," you can get a free RHEL subscription via this program. Earlier this year, Red Hat introduced no-cost RHEL for small production workloads and for customer development teams... Jason Brooks, a Red Hat Open Source Program Office Manager explained: Supporting the open-source software ecosystem is a core objective for Red Hat... We know that we are part of a larger, interdependent ecosystem that we benefit from and which we do our best to foster and support. This support comes in many forms, but often includes helping open source software projects, foundations, and standards bodies access enterprise technologies for development and testing. We frequently provide no-cost access to RHEL to these groups, but the process isn't as formalized, consistent, accessible, or transparent as we'd like it to be. With the announcement that we will be shifting our resources to CentOS Stream at the end of 2021, we want to make sure that those organizations engaged with open source have access to RHEL as they build and test the future of open-source software... The GNOME Foundation's executive director Neil McGovern, said: As a non-profit, we rely on donations to help us achieve our goal of a world where everyone is empowered by technology they can trust. RHEL subscriptions are an essential part of this. With full operating system management and security updates, we can concentrate on the services we provide to GNOME users and developers without having to worry about the underlying systems. Red Hat has generously provided these services to GNOME at zero cost for years, and we look forward to continuing our relationship for a long time to come. GNOME is also the default desktop in RHEL Workstation.' -- source: https://linux.slashdot.org/story/21/02/27/0235247 Chdeers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Brave Privacy Bug Exposed Tor Onion URLs To Your DNS Provider
by Peter Reutemann 01 Mar '21

01 Mar '21

'Brave Browser had a privacy issue that leaked the Tor onion URL addresses you visited to your locally configured DNS server, "exposing the dark web websites you visit...", writes Bleeping Computer. Long-time Slashdot reader AmiMoJo quotes their report: To access Tor onion URLs, Brave added a "Private Window with Tor" mode that acts as a proxy to the Tor network. When you attempt to connect to an onion URL, your request is proxied through volunteer-run Tor nodes who make the request for you and send back the returned HTML. Due to this proxy implementation, Brave's Tor mode does not directly provide the same level of privacy as using the Tor Browser. When using Brave's Tor mode, it should forward all requests to the Tor proxies and not send any information to any non-Tor Internet devices to increase privacy. However, a bug in Brave's "Private window with Tor" mode is causing the onion URL for any Tor address you visit to also be sent as a standard DNS query to your machine's configured DNS server.

Introducing Crowdsec: a Modernized, Collaborative Massively Multiplayer Firewall
by Peter Reutemann 01 Mar '21

01 Mar '21

'CrowdSec is a massively multiplayer firewall designed to protect Linux servers, services, containers, or virtual machines exposed on the Internet with a server-side agent. It was inspired by Fail2Ban and aims to be a modernized, collaborative version of that intrusion-prevention tool. CrowdSec is free and open-source (under an MIT License), with the source code available on GitHub. It uses a behavior analysis system to qualify whether someone is trying to hack you, based on your logs. If your agent detects such aggression, the offending IP is then dealt with and sent for curation. If this signal passes the curation process, the IP is then redistributed to all users sharing a similar technological profile to 'immunize' them against this IP. The goal is to leverage the power of the crowd to create a real-time IP reputation database. As for the IP that aggressed your machine, you can choose to remedy the threat in any manner you feel appropriate. Ultimately, CrowdSec leverages the power of the community to create an extremely accurate IP reputation system that benefits all its users. It was clear to the founders that Open Source was going to be one of the main pillars of CrowdSec. The project's founders have been working on open-source projects for decades — they didn't just jump on the train. Rather, they are strong Open Source believers. They believe that the crowd is key to the mass hacking plague we are experiencing, and that Open Source is the best lever to create a community and have people contribute their knowledge to the project, ultimately make it better and more secure. The solution recently turned 1.x, introducing a major architectural change: the introduction of a local REST API.' -- source: https://linux.slashdot.org/story/21/02/27/2215223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox's Total Cookie Protection Aims To Stop Tracking Between Multiple Sites
by Peter Reutemann 24 Feb '21

24 Feb '21

'As part of its war on web tracking, Mozilla is adding a new tool to Firefox aimed at stopping cookies from keeping tabs on you across multiple sites. From a report: The "Total Cookie Protection" feature is included in the web browser's latest release -- alongside multiple picture-in-picture views -- and essentially works by keeping cookies isolated between each site you visit. Or, in Mozilla's words: "By creating a separate cookie jar for every website." Firefox's new feature pares with last month's network partitioning tool, which works by splitting the Firefox browser cache on a per-website basis to prevent tracking across the web, itself targeted at blocking more stubborn "supercookies." According to Mozilla, these types of cookies are more difficult to delete and block as they are stored in obscure parts of the browser, including in Flash storage, ETags, and HSTS flags. Both tools are available as part of Firefox's enhanced tracking protection suite in "strict mode" on desktop and Android.' -- source: https://news.slashdot.org/story/21/02/23/1513219 -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New TLD For Spammers
by Lawrence D'Oliveiro 21 Feb '21

21 Feb '21

Normally I get only a handful of spam e-mails per day -- greylisting is that effective at keeping most of them out. But over the past couple of days, this moved closer to being a flood like the bad old days, with several dozen coming in over the last 24 hours or so. Doing a quick check, all the ones I looked at were being sent from *.cyou domains. Yes, there really is such a top-level domain now. But given that it seems to be used entirely for spam, it’s easy enough to add a line to my block_sender file: /^.+(a).+\.cyou$/ REJECT

The world’s second-most popular desktop operating system isn’t macOS anymore
by Peter Reutemann 21 Feb '21

21 Feb '21

'For ages now, every annual report on desktop operating system market share has had the same top two contenders: Microsoft's Windows in a commanding lead at number one and Apple's macOS in distant second place. But in 2020, Chrome OS became the second-most popular OS, and Apple fell to third. That's according to numbers from market data firm IDC and a report on IDC's data by publication GeekWire. Chrome OS had passed macOS briefly in individual quarters before, but 2020 was the first full year when Apple's OS took third place. Despite the fact that macOS landed in third, viewing this as an example of Google beating out Apple directly might not be accurate. Rather, it's likely that Chrome OS has been primarily pulling sales and market share away from Windows at the low end of the market. Mac market share actually grew from 6.7 percent in 2019 to 7.5 percent in 2020. Meanwhile, Chrome OS skyrocketed from 6.4 percent in 2019 to 10.8 percent in 2020. Windows fell from 85.4 percent to 80.5 percent.' -- source: https://arstechnica.com/gadgets/2021/02/the-worlds-second-most-popular-desk… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New browser-tracking hack works even when you flush caches or go incognito
by Peter Reutemann 21 Feb '21

21 Feb '21

'The prospect of Web users being tracked by the sites they visit has prompted several countermeasures over the years, including using Privacy Badger or an alternate anti-tracking extension, enabling private or incognito browsing sessions, or clearing cookies. Now, websites have a new way to defeat all three. The technique leverages the use of favicons, the tiny icons that websites display in users’ browser tabs and bookmark lists. Researchers from the University of Illinois, Chicago said in a new paper that most browsers cache the images in a location that’s separate from the ones used to store site data, browsing history, and cookies. Websites can abuse this arrangement by loading a series of favicons on visitors’ browsers that uniquely identify them over an extended period of time. [...] The attack works against Chrome, Safari, Edge, and until recently Brave, which developed an effective countermeasure after receiving a private report from the researchers. Firefox would also be susceptible to the technique, but a bug prevents the attack from working at the moment.' -- source: https://arstechnica.com/information-technology/2021/02/new-browser-tracking… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Top Banks Join Linux and Open-Source Patent Protection Group
by Peter Reutemann 21 Feb '21

21 Feb '21

'ZDNet reports: When it comes to defending the intellectual property (IP) rights of Linux and open-source software, global leading banks aren't the first businesses to come to mind. Things have changed. Barclays, the London-based global corporate and investment bank, and the TD Bank Group, with its 26-million global customers, have joined the leading open-source IP defense group, the Open Invention Network (OIN). For years, the OIN, the largest patent non-aggression consortium, has protected Linux from patent attacks and patent trolls. Recently, it expanded its scope from core Linux programs and adjacent open-source code by expanding its Linux System Definition. In particular, that means patents relating to the Android Open Source Project (AOSP) 10 and the Extended File Allocation Table exFAT file system are now protected... Besides joining the OIN, Barclay is also joining the LOT Network. This is another fast-growing nonprofit group of companies that aims to stop patent trolls in their tracks. It has more than 1,100 member companies and covers over 2 million patent assets. Why? The "IP and Patentable Innovations Lead" at TD noted that activity from so-called patent assertion entities "continues to trend upward in the banking industry," according to ZDNet. He argues they "have become a tax on business and we're willing to explore any reasonable means to address such risks..."' -- source: https://news.slashdot.org/story/21/02/20/0244211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Is Now on Mars, Thanks to NASA's Perseverance Rover
by Peter Reutemann 21 Feb '21

21 Feb '21

'"When NASA's Perseverance rover landed on Mars this week, it also brought the Linux operating system to the Red Planet," reports PC Magazine: The tidbit was mentioned in an interview NASA software engineer Tim Canham gave to IEEE Spectrum. The helicopter-like drone on board the Perseverance rover uses a Linux-powered software framework the space agency open-sourced a few years ago. "This the first time we'll be flying Linux on Mars. We're actually running on a Linux operating system," Canham said. It also might be the first time NASA has brought a Linux-based device to Mars. "There isn't a previous use of Linux that I'm aware of, definitely on the previous rovers," Canham told PCMag in an email. Past Mars rovers have used proprietary OSes, largely from the software company Wind River Systems. The same is true for the Perseverance rover itself; the machine has been installed with Wind River's VxWorks, which was used on past Mars missions. The article also notes that the helicopter-like drone Ingenuity "was built using off-the-shelf parts, including Qualcomm's Snapdragon 801 processor, a smartphone chip." "Ingenuity is purely a technology demonstration," notes ZDNet. "It's not designed to support the Perseverance mission, which is searching for signs of ancient life and collecting rock and dirt samples for later missions to return to Earth. Its mission is to show that it's possible to fly on Mars using commercial off-the-shelf hardware and open-source software."' -- source: https://science.slashdot.org/story/21/02/20/1830240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

LastPass' Free Tier Will Become a Lot Less Useful Next Month
by Peter Reutemann 17 Feb '21

17 Feb '21

'LastPass is adding new restrictions to its free subscription tier starting March 16th that'll only allow users to view and manage passwords on one category of devices: mobile or computer. From a report: Mobile users will be limited to iOS and Android phones, iPads, Android tablets, and smartwatches. Computer subscribers will be able to use their passwords from Windows, macOS, and Linux desktops and laptops, the LastPass browser extension, and Windows tablets. Users on LastPass' free tier will be asked to pick between the two options the first time they log in after March 16th, and the company says they'll be able to switch between categories up to three times after they've picked. Although customers are restricted to a single category of devices on the free tier, they'll still be able view and manage passwords from an unlimited number of devices within either the mobile or computer category. LastPass says no users will be locked out of their accounts or lose access to their passwords as a result of the changes. As well as restricting its device types, LastPass is also changing the kinds of customer support free tier users will be able to access. From May 17th, free users will lose access to email support, the company announced.' -- source: https://tech.slashdot.org/story/21/02/16/166221 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Dev creeped out after he fired up Ubuntu VM on Azure, was immediately approached by Canonical sales rep
by Peter Reutemann 16 Feb '21

16 Feb '21

'An Azure customer was outraged after finding himself on the receiving end of an unexpected LinkedIn message from Ubuntu maker Canonical last night. The user, Luca Bongiorni, had spun up an instance of the Linux distro on an Azure corporate subscription in order to evaluate some tooling. Sensibly, the subscription is used as a sandbox for the purpose of testing. Upon clicking "Add new VM", the first option was Ubuntu 18.04, according to Bongiorni, which he selected in order to get his Linux kicks. Shortly after, however, a message turned up from an Enterprise Development representative at Ubuntu with the ominous phrase: "I saw that you spun up an Ubuntu image in Azure," and offering to be a point of contact.' -- source: https://www.theregister.com/2021/02/11/microsoft_azure_ubuntu_data_sharing/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Happy ENIAC Day
by Lawrence D'Oliveiro 16 Feb '21

16 Feb '21

75 years ago today, the University of Pennsylvania launched ENIAC, the first non-classified programmable digital computer <https://www.theregister.com/2021/02/15/eniac_day/>. (The UK Colossus preceded it, but the existence of that was kept secret for a few more decades.) This was not a “stored-program” machine, at least not at first: programming was initially done using patch cords and switches. You may also like this interview <https://www.youtube.com/watch?v=buAYHonF968> with the late Jean Jennings Bartik, about some of the fun she and her colleagues had programming the ENIAC, and the innovations they came up with. The electronics engineers who built the first computers didn’t think of programming as a very interesting activity, so they left it to women.

History Of VLC
by Lawrence D'Oliveiro 15 Feb '21

15 Feb '21

Found this <https://www.protocol.com/vlc-history-open-source> linked from a report on the new version of VLC, describing the history of the project back to its beginnings. Once upon a time there was “VideoLAN Server” and “VideoLAN Client”, but today everything has been rolled into a single “VLC” program. Of course it’s been in the sights of Intellectual Property lawyers for a long time: VLC's success also put it on the radar of patent lawyers, who started to send the VideoLAN team a growing number of legal threats, looking to extract licensing fees. Over the years, the VLC team received hundreds such legal threats over alleged patent violations. Virtually all of them were without merit, according to Kempf. Many were based on U.S. software patents that weren't easily enforceable in Europe. Others were citing technology that VLC was using even before companies tried to patent it. "No one is checking whether these patents are valid," Kempf said. "It's a complete mafia; it's protection money." The open-source x264 codec implementation was also an offshoot of VLC. And Jean-Baptiste Kempf says he could have done those software-bundling deals where unwary users get all kinds of things installed on their PCs in addition to the package they thought they were installing, and thereby earned tens of millions of dollars, but he didn’t want to. The project gets money from donations, but also from companies employing developers to build custom implementations for their set-top boxes.

Why NVidia Really Wants To Buy ARM
by Lawrence D'Oliveiro 13 Feb '21

13 Feb '21

From <https://arstechnica.com/gadgets/2021/02/nvidia-wants-to-buy-cpu-designer-ar…>: Owning Arm outright would also allow Nvidia much greater leeway to innovate upon the design. We've spoken to several vendors who described the sort of innovation that the RISC-V architecture allows as effectively impossible with Arm; the vendors have said "they just won't let you" make changes, like adjustments to the instruction set. If Nvidia owns Arm, it will no longer face such restrictions. And it will be the only company in such a position with respect to ARM. That may make it more competitive with RISC-V, but it will likely just drive other vendors away from ARM ... and towards RISC-V.

Hauwei router source code.
by Ian Stewart 10 Feb '21

10 Feb '21

Hi, I recently searched for the User Manual for a Huawei Model HG253s V2 Home Gateway. I found the document which is dated 2015. Google also found the HG253s V2 open source code.zip file from February 04, 2015 @117MB. Featuring the Linux kernel version 2.6.30 this file was available from huawei.com at... https://consumer-tkb.huawei.com/weknow/servlet/download/public?contextNo=S1… So, based on what I've heard from the CIA, MI6, GCSB and Five-Eyes, I'm now looking through the source code for the functions that send the messages back to the mothership in China 😉 ...Haven't found any code that does this so far ! In summary. I was surprised that Huawei release their source code. Admittedly it's for a device that's at least five years old and, for all I know, it may be the same code that OpenWRT use. I guess I'll still have to wait a while for the source code for the Huawei 5G routers. cheers, Ian.

Most Anti-Zoombombing Measures Are Futile
by Lawrence D'Oliveiro 05 Feb '21

05 Feb '21

How do you keep unwanted busybodies out of your videoconference meetings? This analysis <https://arstechnica.com/information-technology/2021/02/zoombombing-counterm…> concludes that common measures like password-protected meetings and waiting rooms are ineffective because they guard against the wrong threats. One thing that does help is giving each invited participant a unique join link. Ideally this link can only be used once. But even if not, it still allows organizers to identify the source of a leak to a zoombomber.

Firefox 85 Hammers the Final Nail Into the Adobe Flash Coffin
by Peter Reutemann 03 Feb '21

03 Feb '21

'With Mozilla's release of Firefox 85 on Tuesday, Adobe's once ubiquitous Flash technology is really gone for good. The software had been widely used to expand gaming, video and animation on the web, though Adobe stopped supporting it at the end of 2020. Firefox was the last major browser to support Flash. From a report: Apple, whose late boss Steve Jobs helped sink Flash by banning it from iPhones and iPads, ditched Flash with Safari 14 in September 2020. Google Chrome, the most widely used browser, completely excised it on Jan. 19 with version 88. Microsoft's Edge 88 followed suit on Jan. 21. The schedule of removals shows just how hard it is to advance technology foundations as widely used as the web. Browser makers for years wanted to remove Flash, replacing it with more advanced standards built directly into the web. Jobs' "Thoughts on Flash" letter in 2010 solidified the opposition, and Adobe started recognizing the software's doom by scrapping the Android version of Flash in 2011. It's taken years of effort to drop Flash completely. Adobe took until 2017 to announce that Flash would be completely unsupported at the end of 2020, and still some are willing to jump through lots of hoops to keep Flash around a little longer.' -- source: https://it.slashdot.org/story/21/01/26/1618254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

ActiveX All Over Again?
by Lawrence D'Oliveiro 02 Feb '21

02 Feb '21

Is Google repeating history, by pushing new browser features regardless of their security implications, like Microsoft did in the bad old days? This article <https://www.theregister.com/2021/02/01/chrome_89_beta_brings_desktop/> reports on Chrome adding some new capabilities that other browser developers (like Mozilla and Apple) feel are far too dangerous to allow, at least in their current form. The problem is, will most users fail to appreciate the security issues, see this feature omission as a bug in those browsers, and reinforce the dominance of Chrome as a result?

The End Of Itanium
by Lawrence D'Oliveiro 02 Feb '21

02 Feb '21

The latest Linux kernel will no longer include support for Intel/HP’s Itanium processors <https://www.theregister.com/2021/02/01/linux_pulls_itanium_support/>. Of course, prior Linux kernels up to 5.10 from December presumably still include such support, while the last version of HP’s own HP-UX 11i for its Itanium-based Integrity servers was v3 from 2007 <https://en.wikipedia.org/wiki/HP-UX#Release_history>. The last working version of Microsoft’s Windows Server for that platform, 2008 R2, came out just a couple of years later, and already dropped some features compared to editions for other platforms <https://en.wikipedia.org/wiki/Windows_Server_2008_R2#Editions>. Intel officially claims to be shipping new Itanium processors up to July this year, but it seems pretty clear the order book is empty. So it looks like the last OS still standing for that platform will be Linux.

Google Threatens To Remove Search in Australia as Spat Escalates
by Peter Reutemann 01 Feb '21

'Google has threatened to disable its search engine in Australia if it's forced to pay local publishers for news, a dramatic escalation of a months-long standoff with the government. From a report: The proposed law, intended to compensate publishers for the value their stories generate for the company, is "unworkable," Mel Silva, managing director for Australia and New Zealand, told a parliamentary hearing Friday. She specifically opposed the requirement that Google pay media companies for displaying snippets of articles in search results. The threat is Google's most potent yet as the digital giant tries to stem a flow of regulatory action worldwide. At least 94% of online searches in Australia go through the Alphabet unit, according to the local competition regulator. "We don't respond to threats," Australia Prime Minister Scott Morrison said Friday. "Australia makes our rules for things you can do in Australia. That's done in our parliament.

TinyPilot KVM Over IP
by Lawrence D'Oliveiro 31 Jan '21

31 Jan '21

Just been watching this review <https://www.youtube.com/watch?v=CyEpshm16HY> of the TinyPilot KVM-over-IP box. It’s purchasable from the maker’s website for US$300-plus, which is a fraction of the price of most other KVM-over-IP products. It’s built around a Raspberry π 4, using the camera adapter for HDMI in (no use made of the GPIO connector at all). Of course this means it can only support a connection to a single server machine. The source code is on GitHub if you want to build that yourself. The base product offers insecure HTTP-only access; if you want HTTPS, you have to pay extra for the TinyPilot Pro software licence. For comparison, some reader comments mention an alternative “PiKVM” product -- has anyone heard of this?

CERN Gets Its Open Hardware Licence Approved By OSI
by Lawrence D'Oliveiro 31 Jan '21

31 Jan '21

CERN wanted to come up with the hardware equivalent of open-source software licences. Such licences don’t really work well with hardware, because they use terms (like “linking” and “system libraries”) that aren’t applicable to hardware. So they worked with the Open Source Initiative (the custodians of the Open Source Definition) to come up with a selection of three licences, allowing for a choice of strong copyleft (GPL-equivalent), weak copyleft (LGPL-equivalent, I guess) and no copyleft at all. It seems these licences could actually be used for a combination of both hardware and software. <https://www.theregister.com/2021/01/29/cern_ohl_approved/>

Cloning SSD's
by Ian Stewart 31 Jan '21

31 Jan '21

FWIW: My recent experiences with copying SSD's... I recently installed Ubuntu Mate from USB stick to a 120GB SSD. I then updated with all the latest patches. This took about 30 minutes. I then tailored my preferences of Firefox, Terminal, Pluma, etc. Created a Guest account. Installed the NZ dictionary, and added some applications. This took me another 30 minutes. I then needed to do this to 5 more computers. So, to prepare six computers would have taken me a total of about 6 hours. I considered using the utility "dd" to copy a clone of my master disk. Looking through stackoverflow<https://unix.stackexchange.com/questions/144172/full-dd-copy-from-hdd-to-hdd> I found the suggestion to use "cat". I.e. Boot Ubuntu from a USB stick and assuming sda is my master disk and sdb is the clone, then issue the command... $ sudo sh -c 'cat /dev/sda >/dev/sdb' I found this copying took about 15 minutes. However, it didn't give me any progress report during the copying sequence. I then... $ sudo apt install pv ...pv stands for "Pipe Viewer". For the next SSD drive to be cloned I issued the command... $ sudo sh -c 'pv /dev/sda >/dev/sdb' ...which then provided a progress bar that updated every second. With Samsung SSD 120GB drives I found the operation took 13 minutes 13 seconds with a transfer rate of 153MB/s. I later had built another master SSD on a Kingston 120GB SSD and cloned this to another Kingston 120GB SSD which took 10 minutes and had a transfer rate of 200MB/s. I found with the system still powered on, I could unplug the cloned SSD and plug in another blank SSD and start another cloning. Probably not a recommended practice. After booting the clone, I edited /etc/hostname to make each clone unique. Maybe there's something else I should change??? In summary, allowing for a bit of time to physically move the SSD's between machines, I was effectively completing the installation/updating/tailoring at a rate of three PC's an hour. I dunno if this was the right way or the best way, but, so far, the masters and all the clones seem to be working OK. cheers, Ian.

Intel Iris Xe Video Cards Now Shipping To OEMs: DG1 Lands In Desktops
by Peter Reutemann 29 Jan '21

'Ryan Smith, writing at AnandTech: Following plans first unveiled last year during the launch of their DG1 GPU, Intel sends word this morning that the first Iris Xe video cards have finally begun shipping to OEMs. Based on the DG1 discrete GPU that's already being used in Intel's Iris Xe MAX laptop accelerators, the Iris Xe family of video cards are their desktop counterpart, implementing the GPU on a traditional video card. Overall, with specifications almost identical to Xe MAX, Intel is similarly positioning these cards for the entry-level market, where they are being released as an OEM-only part. As a quick refresher, the DG1 GPU is based on the same Xe-LP graphics architecture as Tiger Lake's integrated GPU. In fact, in broad terms the DG1 can be thought of as a nearly 1-to-1 discrete version of that iGPU, containing the same 96 EUs and 128-bit LPDDR4X memory interface as Tiger Lake itself. Consequently, while DG1 is a big first step for Intel -- marking the launch of their first discrete GPU of the modern era -- the company is planning very modestly for this generation of parts. The first DG1 GPUs were shipped in the fall as part of Intel's Iris Xe MAX graphics solution for laptops. At the time, Intel also indicated that a desktop card for OEMs would also be coming in 2021, and now, right on schedule, those desktop cards have begun shipping out.' -- source: https://hardware.slashdot.org/story/21/01/28/1649204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

ProtonMail, Threema, Tresorit and Tutanota Warn EU Lawmakers Over 'Anti-Encryption' Push
by Peter Reutemann 29 Jan '21

29 Jan '21

'Four European apps which secure user data via end-to-end encryption, ProtonMail, Threema, Tresorit and Tutanota, have issued a joint-statement warning over recent moves by EU institutions that they say are setting lawmakers on a dangerous path to backdooring encryption. From a report: Last month the EU Council passed a resolution on encryption that's riven with contradiction -- calling for "security through encryption and security despite encryption" -- which the four e2e app makers believe is a thinly veiled call to backdoor encryption. The European Commission has also talked about seeking "improved access" to encrypted information, writing in a wide-ranging counter-terrorism agenda also published in December that it will "work with Member States to identify possible legal, operational, and technical solutions for lawful access." Simultaneously, the Commission has said it will "promote an approach which both maintains the effectiveness of encryption in protecting privacy and security of communications, while providing an effective response to crime and terrorism." And it has made it clear there will be no 'one silver bullet' as regards the e2e encryption security 'challenge.' But such caveats are doing nothing to alleviate the concerns of e2e encrypted app makers -- who are convinced proposals from the Council of the EU, which is involved in adopting the bloc's laws (though the Commission usually drafts legislation), sums to an push toward backdoors. "While it's not explicitly stated in the resolution, it's widely understood that the proposal seeks to allow law enforcement access to encrypted platforms via backdoors," the four app makers write, going on to warn that such a move would fatally underline the security EU institutions also claim to want to maintain. "The resolution makes a fundamental misunderstanding: Encryption is an absolute, data is either encrypted or it isn't, users have privacy or they don't," they go on. "The desire to give law enforcement more tools to fight crime is obviously understandable. But the proposals are the digital equivalent of giving law enforcement a key to every citizen's home and might begin a slippery slope towards greater violations of personal privacy."' -- source: https://yro.slashdot.org/story/21/01/28/1724250 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GitLab Reshuffles Its Paid Subscription Plans, Drops Its Bronze/Starter Tier
by Peter Reutemann 28 Jan '21

28 Jan '21

'GitLab, the increasingly popular DevOps platform, today announced a major update to its subscription model. The company is doing away with its $4/month Bronze/Starter package. Current users will be able to renew one more time at the existing price or move to a higher tier (and receive a significant discount for the first three years after they do so). The company's free tier, it is worth noting, is not going away and GitLab argues that it includes "89% of the features in Bronze/Starter." To ease the pain, Bronze users will be able to renew their existing subscription before January 26, 2022 for an additional year at the existing price. They can also opt to move to the Premium tier at a discounted price for the next three years, starting at $6/user/month in Year 1, but that price then goes up to $9/user/month and $15/user/month in Year 2 and 3 respectively. For new users, the Bronze package is no longer available, starting now. With this change, GitLab now offers three tiers: Free, Premium and Ultimate (it's also doing away with the "Silver/Premium" and "Gold/Ultimate" naming). "The Bronze tier, we were selling at a loss," GitLab founder and CEO Sid Sijbrandij told TechCrunch. "We were just losing money every time we sold it -- just on hosting and support. To be a sustainable business, this was a move we had to make. It's a big transition for our customers but we want to make sure we're a sustainable company and we can keep investing."' -- source: https://tech.slashdot.org/story/21/01/27/215226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Reddit 1: Wall Street 0
by Lawrence D'Oliveiro 28 Jan '21

28 Jan '21

Something very peculiar happened last week: a group of small-time stock traders who hang out on Reddit took on a well-funded Wall Street money manager, and won. What happened was, a company called Melvin Capital took out a “short position” on shares in GameStop--that is, they put money on a bet that the stock value would go down. The Redditors (part of a subreddit called “wallstreetbets”) figured out that this position was vulnerable, and bet against it by buying up GameStop shares. This drove up the price, forcing Melvin to either put up or shut up--put up a bunch of money to back up their position, or give up and lose an even bigger bunch of money. In other words, Melvin was caught in a “short squeeze”, which drove it to the verge of bankruptcy. A good, clear intro to the whole story is here <https://arstechnica.com/gaming/2021/01/the-complete-morons-guide-to-gamesto…>.

10-year-old Sudo Bug Lets Linux Users Gain Root-Level Access
by Peter Reutemann 28 Jan '21

28 Jan '21

'A major vulnerability impacting a large chunk of the Linux ecosystem has been patched today in Sudo, an app that allows admins to delegate limited root access to other users. From a report: The vulnerability, which received a CVE identifier of CVE-2021-3156, but is more commonly known as "Baron Samedit," was discovered by security auditing firm Qualys two weeks ago and was patched earlier today with the release of Sudo v1.9.5p2. In a simple explanation provided by the Sudo team today, the Baron Samedit bug can be exploited by an attacker who has gained access to a low-privileged account to gain root access, even if the account isn't listed in /etc/sudoers -- a config file that controls which users are allowed access to su or sudo commands in the first place.' -- source: https://linux.slashdot.org/story/21/01/27/1820205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

26 Jan '21

'A coalition of tech companies announced today the launch of Open Web Docs, a new initiative to help write documentation for Web APIs, JavaScript, and other web tooling and platforms. From a report: The new project does not view itself as a replacement for MDN Web Docs, a website hosted by Mozilla, where all browser makers agreed to move the official Web API documentation back in October 2017, and stop developing their own, often diverging, documentation sites. Instead, in a press release and FAQ today, the Open Web Docs team said their role is to fund, coordinate, and contribute to MDN Docs going forward. The new initiative comes after Mozilla laid off 250 employees last summer, including many of its MDN Web Docs staff.

Hacker Leaks Data of 2.28 Million Dating Site Users
by Peter Reutemann 26 Jan '21

26 Jan '21

'ZDNet: A well-known hacker has leaked the details of more than 2.28 million users registered on MeetMindful.com, a dating website founded in 2014, ZDNet has learned this week from a security researcher. The dating site's data has been shared as a free download on a publicly accessible hacking forum known for its trade in hacked databases. The leaked data, a 1.2 GB file, appears to be a dump of the site's users database. The content of this file includes a wealth of information that users provided when they set up profiles on the MeetMindful site and mobile apps. Some of the most sensitive data points included in the file include: Real names; Email addresses; City, state, and ZIP details; Body details; Dating preferences; Marital status; Birth dates; Latitude and longitude; IP addresses; Bcrypt-hashed account passwords; Facebook user IDs; and Facebook authentication tokens. Messages exchanged by users were not included in the leaked file; however, this does not make the entire incident less sensitive. The data leak, which is still available for download, was released by a threat actor who goes by the name of ShinyHunters. They also were responsible for leaking the details of millions of users registered on Teespring.

When Adobe Stopped Flash Content, It Also Stopped A Chinese Railroad
by Peter Reutemann 25 Jan '21

25 Jan '21

'Jalopnik shares a story for our times: Adobe's Flash, the web browser plug-in that powered so very many crappy games, confusing interfaces, and animated icons of the early web like Homestar Runner is now finally gone, after a long, slow, protracted death. For most of us, this just means that some goofy webgame you searched for out of misplaced nostalgia will no longer run. For a select few in China, though, the death of Flash meant being late to work, because the city of Dalian in northern China was running their railroad system on it. Yes, a railroad, run on Flash, the same thing used to run "free online casinos" and knockoff Breakout games in mortgage re-fi ads... Hell, YouTube used to run on Flash until 2015. It wasn't all stupid little web games but, that said, I can't for the life of me fathom why anyone would want to run a freaking railroad network on it, with physical, multi-ton moving railcars full of human beings on it. So, when Adobe finally killed Flash-based content from running, this Tuesday Dalian's railroad network found itself ground to a halt for 20 hours. The railroad's technicians did get everything back up and running, but the way they did this is fascinating, too. They didn't switch the rail management system to some other, more modern codebase or software installation; instead, they installed a pirated version of Flash that was still operational. The knockoff version seems to be known as "Ghost Version." This, along with installing an older version of the Flash player to work with the knockoff Flash server setup, "solved" the problem, and the railroad was back up and running.' -- source: https://tech.slashdot.org/story/21/01/24/189207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Chrome 88 Released, Removing Adobe Flash -- and FTP
by Peter Reutemann 24 Jan '21

24 Jan '21

'Google released Chrome 88 this week — and besides improving its dark mode support, they removed support for both Adobe Flash and FTP. PC World calls it "the end of two eras." The most noteworthy change in this update is what's not included. Chrome 88 lays Adobe Flash and the FTP protocol to rest. RIP circa-2000 Internet. Neither comes as a surprise, though it's poetic that they're being buried together. Adobe halted Flash Player downloads at the end of 2020, making good on a promise made years before, and began blocking Flash content altogether a couple weeks later. Removing Flash from Chrome 88 is just Google's way of flushing the toilet. On the other hand, FTP isn't dead, but it is now for Chrome users. The File Transport Protocol has helped users send files across the Internet for decades, but in an era of prolific cloud storage services and other sharing methods, its use has waned. Google started slowly disabling FTP support in Chrome 86, per ZDNet, and now you'll no longer be able to access FTP links in the browser. Look for standalone FTP software instead if you need it, such as FileZilla. That's not all. Mac users should be aware that Chrome 88 drops support for OS X 10.10 (OS X Yosemite). Yosemite released in 2014 and received its last update in 2017... But Google killing Flash and FTP might be the footnotes that hit old-school web users in the feels. Chrome 88 will also block non-encrypted downloads originating from an encrypted page, the article reports. And the Verge notes Chrome also offers less intrusive website permission requests (as an experimental feature enabled from chrome://flags/#permission-chip ), while Bleeping Computer describes Chrome 88's new experimental feature for searching through all your open tabs. And Chrome's blog points out some additional features under the hood: Chrome 88 will heavily throttle chained JavaScript timers for hidden pages in particular conditions. This will reduce CPU usage, which will also reduce battery usage. There are some edge cases where this will change behavior, but timers are often used where a different API would be more efficient, and more reliable.' -- source: https://slashdot.org/story/21/01/23/2018224 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Why AWS Is Forking Elasticsearch and Kibana
by Peter Reutemann 24 Jan '21

24 Jan '21

'Steven J. Vaughan-Nichols writes at ZDNet: When Elastic, makers of the open-source search and analytic engine Elasticsearch, went after Amazon Web Services (AWS) by changing its license from the open-source Apache 2.0-license ALv2) to the non-open-source friendly Server Side Public License, I predicted "we'd soon see AWS-sponsored Elasticsearch and Kibana forks." The next day, AWS tweeted it "will launch new forks of both Elasticsearch and Kibana based on the latest Apache 2.0 licensed codebases." Well, that didn't take long! In a blog post, AWS explained that since Elastic is no longer making its search and analytic engine Elasticsearch and its companion data visualization dashboard Kibana available as open source, AWS is taking action. "In order to ensure open source versions of both packages remain available and well supported, including in our own offerings, we are announcing today that AWS will step up to create and maintain an ALv2-licensed fork of open-source Elasticsearch and Kibana.... AWS brings years of experience working with these codebases, as well as making upstream code contributions to both Elasticsearch and Apache Lucene, the core search library that Elasticsearch is built on — with more than 230 Lucene contributions in 2020 alone... We're in this for the long haul, and will work in a way that fosters healthy and sustainable open source practices — including implementing shared project governance with a community of contributors..." Yet another company, Logz.io, a cloud-monitoring company, and some partners have announced that it will launch a "true" open source distribution for Elasticsearch and Kibana.' -- source: https://news.slashdot.org/story/21/01/23/0245229 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Brad Cox, Creator of Objective-C Programming Language, Dies At 76
by Peter Reutemann 24 Jan '21

24 Jan '21

'We have learned that Brad Cox, computer scientist known mostly for creating the Objective-C programming language with his business partner Tom Love, died on January 2, 2021 at his residence. He was 76. >From a Legacy.com post: Brad was born on May 2, 1944 in Fort Benning, Georgia, to the late Nancy Hinson Cox and Dewey McBride Cox of Lake City, South Carolina. Brad grew up on the family's dairy farm in South Carolina but found himself most interested in science. After graduating from Lake City High School, he received his Bachelor of Science Degree in Organic Chemistry and Mathematics from Furman University, and his Ph.D. from the Department of Mathematical Biology at the University of Chicago, and worked on an early form of neural networks. He soon found himself more interested in computers and got a job at International Telephone and Telegraph (ITT) and later joined Schlumbeger -- Doll Research Labs, and ultimately formed his own Connecticut startup, Productivity Products International (PPI) later named Stepstone. Among his first known software projects, he wrote a PDP-8 program for simulating clusters of neurons. He worked at the National Institutes of Health and Woods Hole Oceanographic Institute before moving into the software profession. Dr. Cox was an entrepreneur, having founded the Stepstone Company together with Tom Love for releasing the first Objective-C implementation. Stepstone hoped to sell "ICPaks" and Dr. Cox focused on building his ICPak libraries and hired a team to continue work on Objective-C, including Steve Naroff. The late Steve Jobs', NeXT, licensed the Objective-C language for it's new operating system, NEXTSTEP. NeXT eventually acquired Objective- C from Stepstone. Objective-C continued to be the primary programming language for writing software for Apple's OS X and iOS.

DDoSers are abusing Microsoft RDP to make attacks more powerful
by Peter Reutemann 24 Jan '21

24 Jan '21

'DDoS-for-hire services are abusing the Microsoft Remote Desktop Protocol to increase the firepower of distributed denial-of-service attacks that paralyze websites and other online services, a security firm said this week. Typically abbreviated as RDP, Remote Desktop Protocol is the underpinning for a Microsoft Windows feature that allows one device to log into another device over the Internet. RDP is mostly used by businesses to save employees the cost or hassle of having to be physically present when accessing a computer. As is typical with many authenticated systems, RDP responds to login requests with a much longer sequence of bits that establish a connection between the two parties. So-called booter/stresser services, which for a fee will bombard Internet addresses with enough data to take them offline, have recently embraced RDP as a means to amplify their attacks, security firm Netscout said. The amplification allows attackers with only modest resources to strengthen the size of the data they direct at targets. The technique works by bouncing a relatively small amount of data at the amplifying service, which in turn reflects a much larger amount of data at the final target. With an amplification factor of 85.9 to 1, 10 gigabytes-per-second of requests directed at an RDP server will deliver roughly 860Gbps to the target. “Observed attack sizes range from ~20 Gbps – ~750 Gbps,” Netscout researchers wrote. “As is routinely the case with newer DDoS attack vectors, it appears that after an initial period of employment by advanced attackers with access to bespoke DDoS attack infrastructure, RDP reflection/amplification has been weaponized and added to the arsenals of so-called booter/stresser DDoS-for-hire services, placing it within the reach of the general attacker population.”' -- source: https://arstechnica.com/information-technology/2021/01/ddosers-are-abusing-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How DNSpooq Attacks Could Poison DNS Cache Records
by Peter Reutemann 24 Jan '21

24 Jan '21

'Earlier this week security experts disclosed details on seven vulnerabilities impacting Dnsmasq, "a popular DNS software package that is commonly deployed in networking equipment, such as routers and access points," reports ZDNet. "The vulnerabilities tracked as DNSpooq, impact Dnsmasq, a DNS forwarding client for *NIX-based operating systems." Slashdot reader Joe2020 shared Help Net Security's quote from Shlomi Oberman, CEO and researcher at JSOF. "Some of the bigger users of Dnsmasq are Android/Google, Comcast, Cisco, Red Hat, Netgear, and Ubiquiti, but there are many more. All major Linux distributions offer Dnsmasq as a package, but some use it more than others, e.g., in OpenWRT it is used a lot, Red Hat use it as part of their virtualization platforms, Google uses it for Android hotspots (and maybe other things), while, for example Ubuntu just has it as an optional package." More from ZDNet: Dnsmasq is usually included inside the firmware of various networking devices to provide DNS forwarding capabilities by taking DNS requests made by local users, forwarding the request to an upstream DNS server, and then caching the results once they arrive, making the same results readily available for other clients without needing to make a new DNS query upstream. While their role seems banal and insignificant, they play a crucial role in accelerating internet speeds by avoiding recursive traffic... Today, the DNSpooq software has made its way in millions of devices sold worldwide [including] all sorts of networking gear like routers, access points, firewalls, and VPNs from companies like ZTE, Aruba, Redhat, Belden, Ubiquiti, D-Link, Huawei, Linksys, Zyxel, Juniper, Netgear, HPE, IBM, Siemens, Xiaomi, and others. The DNSpooq vulnerabilities, disclosed today by security experts from JSOF, are dangerous because they can be combined to poison DNS cache entries recorded by Dnsmasq servers. Poisoning DNS cache records is a big problem for network administrators because it allows attackers to redirect users to clones of legitimate websites... In total, seven DNSpooq vulnerabilities have been disclosed today. Four are buffer overflows in the Dnsmasq code that can lead to remote code execution scenarios, while the other three bugs allow DNS cache poisoning. On their own, the danger from each is limited, but researchers argue they can be combined to attack any device with older versions of the Dnsmasq software... The JSOF exec told ZDNet that his company has worked with both the Dnsmasq project author and multiple industry partners to make sure patches were made available to device vendors by Tuesday's public disclosure.' -- source: https://it.slashdot.org/story/21/01/23/0412253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Talks With TSMC, Samsung To Outsource Some Chip Production
by Peter Reutemann 22 Jan '21

22 Jan '21

'Intel has talked with TSMC and Samsung about the Asian companies making some of its best chips, but the Silicon Valley pioneer is still holding out hope for last-minute improvements in its own production capabilities. Bloomberg reports: After successive delays in its chip fabrication processes, Santa Clara, California-based Intel has yet to make a final decision less than two weeks ahead of a scheduled announcement of its plans, according to people familiar with the deliberations. Any components that Intel might source from Taiwan wouldn't come to market until 2023 at the earliest and would be based on established manufacturing processes already in use by other TSMC customers, said the people, asking not to be identified because the plans are private. Talks with Samsung, whose foundry capabilities trail TSMC's, are at a more preliminary stage, the people said. An Intel spokesperson referred to previous comments by Bob Swan, the company's chief executive officer. Swan has promised investors he'll set out his plans for outsourcing and get Intel's production technology back on track when the company reports earnings Jan. 21. [...] TSMC, the largest maker of semiconductors for other companies, is preparing to offer Intel chips manufactured using a 4-nanometer process, with initial testing using an older 5-nanometer process, according to the people. The company has said it will make test production of 4-nanometer chips available in the fourth quarter of 2021 and volume shipments the following year. The Taiwanese company expects to have a new facility in Baoshan operational by the end of this year, which can be converted to production for Intel if required, one of the people said. TSMC executives previously said the new Baoshan unit would house a research center with 8,000 engineers. While Intel has outsourced production of lower-end chips before, it has kept the manufacturing of its best semiconductors in-house, considering it a competitive strength. Its engineers have historically tailored their designs to the company's manufacturing processes, making a shift to outsourcing of flagship products unthinkable in the past. As the provider of 80% of personal computer and server processors globally, Intel produces hundreds of millions of chips each year. That scale dictates that any potential supplier must create new capacity to accommodate Intel.' -- source: https://hardware.slashdot.org/story/21/01/08/2215226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Aussie Government is trying to protect one lot of multinational companies from the encroachments of another lot; where does fair competition end and protectionism or exploitation begin? <https://www.nzherald.co.nz/business/google-threatens-to-ban-search-button-i…> (By the way, in that old African proverb, the “grass” is the ordinary people who are the inevitable victims in any conflict between major powers.)

Ubuntu Now Runs On Apple Silicon, Devs Say It's 'Completely Usable'
by Peter Reutemann 22 Jan '21

22 Jan '21

'Developers at ARM virtualisation company Corellium have managed to get Ubuntu 20.04 up and running on the new Apple Silicon Mac Mini. And we're not talking 'it boots and prints a load of text' running here. No, this is the full Ubuntu desktop experience -- and it's already being described as "completely usable!" Pretty impressive, right? Even Linus Torvalds wasn't convinced that Linux M1 support was likely to appear anytime soon. He told ZDnet's Steven J. Vaughan-Nichols that: "...the main problem with the M1 for me is the GPU and other devices around it, because that's likely what would hold me off using it because it wouldn't have any Linux support unless Apple opens up." Not that he was entirely wrong, mind. GPU support is indeed a current sticking point in Correllium's Linux for M1 effort. It doesn't (yet) include M1 GPU support meaning 'graphics' handling is done via software rendering.' -- source: https://news.slashdot.org/story/21/01/21/1329258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

NSA Urges System Administrators To Replace Obsolete TLS Protocols
by Peter Reutemann 22 Jan '21

22 Jan '21

'The US National Security Agency has issued a security advisory this month urging system administrators in federal agencies and beyond to stop using old and obsolete TLS protocols. From a report: "NSA recommends that only TLS 1.2 or TLS 1.3 be used; and that SSL 2.0, SSL 3.0, TLS 1.0, and TLS 1.1 not be used," the agency said. "Using obsolete encryption provides a false sense of security because it seems as though sensitive data is protected, even though it really is not," the agency added. Even if TLS 1.2 and TLS 1.3 are deployed, the NSA warns against configuring these two protocols with weak cryptographic parameters and cipher suites.' -- source: https://tech.slashdot.org/story/21/01/21/1646211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Leave.EU Stays In The EU
by Lawrence D'Oliveiro 21 Jan '21

21 Jan '21

The domain that was registered by Brexiteers to promote their campaign for the UK to leave the EU has been re-domiciled to an address in the EU <https://www.theregister.com/2021/01/08/leave_eu_domain_name_hilarity/>. This is because of rule changes that mean UK-based entities are no longer entitled to register .eu names. So if the site wants to stay up under that name, it cannot, contrary to its own name, leave the EU. Just to add to the fun, the individual in the Republic of Ireland who is named on the domain registration claims to know nothing about it, and says he “will be looking into the matter”.

Stopping Alert Volume Going To 100%
by Lawrence D'Oliveiro 20 Jan '21

20 Jan '21

For quite a while now, I’ve been annoyed by the system notification volume going to 100% on my Debian systems, regardless of my attempts to set it to a lower level. For example, when I open the KDE System Settings app, change something, then try to close the window, the sound that accompanies the save/discard/cancel alert is always startlingly loud. I think I have finally found a fix: in your /etc/pulse/daemon.conf, put in a line saying flat-volumes = no (You should find an existing comment “; flat-volumes = yes” that indicates the default.) You can make this new setting take effect in the current session immediately without having to logout or reboot, by executing the following as the currently-logged-in user: pulseaudio -k (This kills and restarts the PulseAudio daemon for your user session.) There are several discussions of the pros and cons of this issue online, going back some years. For example, here <https://bugzilla.redhat.com/show_bug.cgi?id=1265267>. Also a mention about the “flat-volumes” setting in the ever-reliable Arch Linux Wiki here <https://wiki.archlinux.org/index.php/PulseAudio>.

Wine 6.0 Released
by Peter Reutemann 20 Jan '21

20 Jan '21

'Wine 6.0 has been released today and contains over 8,300 changes, according to its full release notes. Windows Central reports: The new release of version 6.0 has thousands of changes, but Wine's website highlights some of the biggest improvements: Core modules in PE format; Vulkan backend for WineD3D; DirectShow and Media Foundation support; and Text console redesign. The full release notes for Wine 6.0 explain that the core DLLs, which include NTDLL, KERNEL32, GDI32, and USER32 are now built in the Portable Executable (PE) format. As a result, people should see improvements for certain copy protection schemes. The update also includes a new mechanism to associate a Unix library with the PE module. This change makes it so systems can call Unix libraries from PE when trying to perform a function that can't be handled by Win32 APIs. Wine 6.0 also includes an experimental Vulkan rendered that translates Direct3D shaders to SPIR-V shaders. In another change related to Direct3D, the Direct3D graphics card database now recognizes more graphics cards and includes updated driver versions.

Brave Becomes First Browser To Add Native Support For the IPFS Protocol
by Peter Reutemann 20 Jan '21

20 Jan '21

'With the release of Brave 1.19 today, Brave has become the first major browser maker to support IPFS, a peer-to-peer protocol meant for accessing decentralized or censored content. From a report: Released in 2015, IPFS stands for InterPlanetary File System. It is a classic peer-to-peer protocol similar to BitTorrent and designed to work as a decentralized storage system. IPFS allows users to host content distributed across hundreds or thousands of systems, which can be public IPFS gateways or private IPFS nodes. Users who want to access any of this content must enter an URL in the form of ipfs://{content_hash_ID}. Under normal circumstances, users would download this content from the nearest nodes or gateways rather than a central server. However, this only works if users have installed an IPFS desktop app or a browser extension. Brave says that with version 1.19, users will be able to access URLs that start with ipfs://, directly from the browser, with no extension needed, and that Brave will natively support ipfs:// links going forward. Since some major websites like Wikipedia have IPFS versions, users in oppressive countries can now use Brave's new IPFS support to go around national firewalls and access content that might be blocked inside their country for political reasons and is available via IPFS.' -- source: https://it.slashdot.org/story/21/01/19/2015252 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Cybersecurity firm FireEye has released today a report detailing the techniques used by the SolarWinds hackers inside the networks of companies they breached. From a report: Together with the report, FireEye researchers have also released a free tool on GitHub named Azure AD Investigator that they say can help companies determine if the SolarWinds hackers (also known as UNC2452) used any of these techniques inside their networks. Today's FireEye report comes as the security firm has spearheaded investigations into the SolarWinds supply chain compromise, together with Microsoft and CrowdStrike.

The NSA warns enterprises to beware of third-party DNS resolvers
by Peter Reutemann 19 Jan '21

19 Jan '21

'DNS over HTTPS is a new protocol that protects domain-lookup traffic from eavesdropping and manipulation by malicious parties. Rather than an end-user device communicating with a DNS server over a plaintext channel—as DNS has done for more than three decades—DoH, as DNS over HTTPS is known, encrypts requests and responses using the same encryption websites rely on to send and receive HTTPS traffic. Using DoH or a similar protocol known as DoT—short for DNS over TLS—is a no brainer in 2021, since DNS traffic can be every bit as sensitive as any other data sent over the Internet. On Thursday, however, the National Security Agency said in some cases Fortune 500 companies, large government agencies, and other enterprise users are better off not using it. The reason: the same encryption that thwarts malicious third parties can hamper engineers’ efforts to secure their networks. “DoH provides the benefit of encrypted DNS transactions, but it can also bring issues to enterprises, including a false sense of security, bypassing of DNS monitoring and protections, concerns for internal network configurations and information, and exploitation of upstream DNS traffic,” NSA officials wrote in published recommendations. “In some cases, individual client applications may enable DoH using external resolvers, causing some of these issues automatically.”' -- source: https://arstechnica.com/information-technology/2021/01/the-nsa-warns-enterp… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Cryptocat Author Gets Insanely Fast Backing To Build P2P Tech For Social Media
by Peter Reutemann 19 Jan '21

19 Jan '21

'TechCrunch: The idea for Capsule started with a tweet about reinventing social media. A day later cryptography researcher, Nadim Kobeissi -- best known for authoring the open-source E2E-encrypted desktop chat app Cryptocat (now discontinued) -- had pulled in a pre-seed investment of $100,000 for his lightweight mesh-networked microservices concept, with support coming from angel investor and former Coinbase CTO Balaji Srinivasan, William J. Pulte and Wamda Capital. The nascent startup has a post-money valuation on paper of $10 million, according to Kobeissi, who is working on the prototype -- hoping to launch an MVP of Capsule in March (as a web app), after which he intends to raise a seed round (targeting $1 million-$1.5 million) to build out a team and start developing mobile apps. For now there's nothing to see beyond Capsule's landing page and a pitch deck (which he shared with TechCrunch for review). But Kobeissi says he was startled by the level of interest in the concept. "I posted that tweet and the expectation that I had was that basically 60 people max would retweet it and then maybe I'll set up a Kickstarter," he tells us. Instead the tweet "just completely exploded" and he found himself raising $100,000 "in a single day" -- with $50,000 paid in there and then. "I'm not a startup guy. I've been running a business based on consulting and based on academic R&D services," he continues. "But by the end of the day -- last Sunday, eight days ago -- I was running a Delaware corporation valued at $10 million with $100,000 in pre-seed funding, which is insane. Completely insane."' -- source: https://news.slashdot.org/story/21/01/18/2144252 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

OpenWRT Forum User Data Stolen In Weekend Data Breach
by Peter Reutemann 19 Jan '21

19 Jan '21

'The OpenWRT forum, a large community of enthusiasts of alternative, open-source operating systems for routers, announced a data breach over the weekend. Bleeping Computer reports: The attack occurred on Saturday, around 04:00 (GMT), when an unauthorized third party gained admin access to and copied a list with details about forum users and related statistical information. The intruder used the account of an OpenWRT administrator. Although the account had "a good password," additional security provided by two-factor authentication (2FA) was not active. Email addresses and handles of the forum users have been stolen, the moderators say. They add that they believe the attacker was not able to download the forum database, meaning that passwords should be safe. However, they reset all the passwords on the forum just to be on the safe side and invalidated all the API keys used for project development processes. Users have to set the new password manually from the login menu by providing their user name and following the "get a new password" instructions. Those logging in using GitHub credentials are advised to reset or refresh it. The OpenWRT forum credentials are separate from the Wiki. Currently, there is no suspicion that the Wiki credentials have been compromised in any way. OpenWRT forum administrators warn that since this breach exposed email addresses, users may become targets of credible phishing attempts.

DuckDuckGo Surpasses 100 Million Daily Search Queries For the First Time
by Peter Reutemann 19 Jan '21

'Privacy-focused search engine DuckDuckGo reached a major milestone in its 12-year-old history last week when it recorded on Monday its first-ever day with more than 100 million user search queries. From a report: The achievement comes after a period of sustained growth the company has been seeing for the past two years, and especially since August 2020, when the search engine began seeing more than 2 billion search queries a month on a regular basis. The numbers are small in comparison to Google's 5 billion daily search queries but it's a positive sign that users are looking for alternatives. DuckDuckGo's popularity comes after the search engine has expanded beyond its own site and now currently offers mobile apps for Android and iOS, but also a dedicated Chrome extension. More than 4 million users installed these apps and extension, the company said in a tweet in September 2020.' -- source: https://tech.slashdot.org/story/21/01/18/1450258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How Tim Berners-Lee Will Fix the Internet
by Peter Reutemann 18 Jan '21

18 Jan '21

'"Sir Tim Berners-Lee, the British computer scientist who was knighted for inventing the internet navigation system known as the World Wide Web, wants to re-make cyberspace once again," reports Reuters: With a new startup called Inrupt, Berners-Lee aims to fix some of the problems that have handicapped the so-called open web in an age of huge, closed platforms such as Facebook. Building on ideas developed by an open-source software project called Solid, Inrupt promises a web where people can use a single sign-on for any service and personal data is stored in "pods," or personal online data stores, controlled by the user. "People are fed up with the lack of controls, the silos," said Berners-Lee, co-founder and chief technology officer of Inrupt, in an interview at the Reuters Next conference... John Bruce, a veteran technology executive who is CEO of Inrupt, said the company had signed up Britain's National Health Service, the BBC and the government of Flanders in Belgium as pilot customers, and hoped to announce many more by April... A key aim for Inrupt is to get software developers to write programs for the platform. Inrupt, like the original web, is at its core mostly a set of protocols for how machines talk to one another, meaning that specific applications bring it to life. "The use cases are so broad, it's like a do-over for the web," Berners-Lee said. In a video interview, Berners-Lee tells Reuters that what people are worried about isn't privacy per se but "the lack of empowerment" — for example, to collaborate with people. And then he acknowledges that the worldwide web does suffer from limited access control. "I wanted it to be a collaborative space, but in a way that was naive, because collaborative spaces you need to be private. You need to start off with just a limited sharing, and then you allow the sharing to increase." Social networks provided some features like a unique login and identity. But unfortunately, then "The large social networks will tend to get larger" — and ultimately without a single global signon, users then become trapped in separate silos.' -- source: https://tech.slashdot.org/story/21/01/16/2336244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Jamie Zawinski Calls Cinnamon Screensaver Lock-Bypass Bug 'Unconscionable'
by Peter Reutemann 18 Jan '21

18 Jan '21

'Legendary programmer Jamie Zawinski has worked on everything from the earliest releases of the Netscape Navigator browser to XEmacs, Mozilla, and, of course, the XScreenSaver project. Now Slashdot reader e432776 writes: JWZ continues to track issues with screensavers on Linux (since 2004!), and discusses a new bug in cinnamon-screensaver. Long-standing topics like X11, developer interaction, and code licensing all feature. Solutions to these long-standing issues remain elusive. Jamie titled his blog post "I told you so, 2021 edition": You will recall that in 2004 , which is now seventeen years ago, I wrote a document explaining why I made the design trade-offs that I did in XScreenSaver, and in that document I predicted this exact bug as my example of, "this is what will happen if you don't do it this way." And they went and made that happen. Repeatedly. Every time this bug is re-introduced, someone pipes up and says something like, "So what, it was a bug, they've fixed it." That's really missing the point. The point is not that such a bug existed, but that such a bug was even possible. The real bug here is that the design of the system even permits this class of bug. It is unconscionable that someone designing a critical piece of security infrastructure would design the system in such a way that it does not fail safe . Especially when I have given them nearly 30 years of prior art demonstrating how to do it right, and a two-decades-old document clearly explaining What Not To Do that coincidentally used this very bug as its illustrative strawman! These bugs are a shameful embarrassment of design -- as opposed to merely bad code... ZDNet reports that Linux Mint has issued a patch for Cinnamon that fixes the screensaver bug. But HotHardware notes that it was discovered when "one Dad let the kids play with the keyboard. This button-mashing actually crashed the machine's screensaver by sheer luck, allowing them onto the desktop, ultimately leading to the discovery of a high priority security vulnerability for the Linux Mint team." But that's not the only thing bothering Jamie Zawinski: Just to add insult to injury, it has recently come to my attention that not only are Gnome-screensaver, Mint-screensaver and Cinnamon-screensaver buggy and insecure dumpster fires, but they are also in violation of my license and infringing my copyright. XScreenSaver was released under the BSD license, one of the oldest and most permissive of the free software licenses. It turns out, the Gnome-screensaver authors copied large parts of XScreenSaver into their program, removed the BSD license and slapped a GPL license on my code instead -- and also removed my name. Rude... Mint-screensaver and Cinnamon-screensaver, being forks and descendants of Gnome-screensaver, have inherited this license violation and continue to perpetuate it. Every Linux distro is shipping this copyright- and license-infringing code. I eagerly await hearing how they're going to make this right.' -- source: https://tech.slashdot.org/story/21/01/17/0024243 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Interview With Jon “maddog” Hall
by Lawrence D'Oliveiro 17 Jan '21

17 Jan '21

Been watching this nearly-hour-long conversation <https://www.youtube.com/watch?v=EZMA3Ge144U> with Jon “maddog” Hall, who if you don’t know him, was very likely the inspiration for the famous Dilbert cartoon featuring the Unix-using neckbeard telling the corporate jobsworth to “get a better computer” <https://dilbert.com/strip/1995-06-24>. Seems that there were several round-number anniversaries related to Unix coming due in 2019 (the year after the video was made), including the 50th anniversary of its creation at Bell Labs. After an early career on IBM mainframe equipment, maddog got a job as a sysadmin at Bell Labs, where he was introduced to Unix. Then he did various different jobs over many years at DEC. At about the half-hour mark, he talks about how he met Linus Torvalds, and asked the latter about porting his still-only-32-bit x86-only fledgling Linux kernel onto the 64-bit Alpha architecture. Linus wanted to do this, but he couldn’t get an Alpha machine from the Helsinki DEC office. So maddog went to bat, pulled a few strings, and got one for him. And it took just 9 months to take Linux from being x86-only and 32-bit-only to being cross-platform and 64-bit-native.

Windows 10 Bug Corrupts Your Hard Drive On Seeing This File's Icon
by Peter Reutemann 15 Jan '21

15 Jan '21

'An unpatched zero-day in Microsoft Windows 10 allows attackers to corrupt an NTFS-formatted hard drive with a one-line command. Bleeping Computer reports: In August 2020, October 2020, and finally this week, infosec researcher Jonas L drew attention to an NTFS vulnerability impacting Windows 10 that has not been fixed. When exploited, this vulnerability can be triggered by a single-line command to instantly corrupt an NTFS-formatted hard drive, with Windows prompting the user to restart their computer to repair the corrupted disk records. The researcher told BleepingComputer that the flaw became exploitable starting around Windows 10 build 1803, the Windows 10 April 2018 Update, and continues to work in the latest version. What's worse is, the vulnerability can be triggered by standard and low privileged user accounts on Windows 10 systems. [...] It is unclear why accessing this attribute corrupts the drive, and Jonas told BleepingComputer that a Registry key that would help diagnose the issue doesn't work. One striking finding shared by Jonas with us was that a crafted Windows shortcut file (.url) that had its icon location set to C:\:$i30:$bitmap would trigger the vulnerability even if the user never opened the file! As observed by BleepingComputer, as soon as this shortcut file is downloaded on a Windows 10 PC, and the user views the folder it is present in, Windows Explorer will attempt to display the file's icon. To do this, Windows Explorer would attempt to access the crafted icon path inside the file in the background, thereby corrupting the NTFS hard drive in the process. Next, "restart to repair hard drive" notifications start popping up on the Windows PC -- all this without the user even having opened or double-clicked on the shortcut file.

Google Reveals Sophisticated Windows and Android Hacking Operation
by Peter Reutemann 15 Jan '21

15 Jan '21

'Google published a six-part report this week detailing a sophisticated hacking operation that the company detected in early 2020 and which targeted owners of both Android and Windows devices. >From a report: The attacks were carried out via two exploit servers delivering different exploit chains via watering hole attacks, Google said. "One server targeted Windows users, the other targeted Android," Project Zero, one of Google's security teams, said in the first of six blog posts. Google said that both exploit servers used Google Chrome vulnerabilities to gain an initial foothold on victim devices. Once an initial entry point was established in the user's browsers, attackers deployed an OS-level exploit to gain more control of the victim's devices. The exploit chains included a combination of both zero-day and n-day vulnerabilities, where zero-day refers to bugs unknown to the software makers, and n-day refers to bugs that have been patched but are still being exploited in the wild.' -- source: https://tech.slashdot.org/story/21/01/14/1610220 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Windows 10X for Single Screens Leaks
by Peter Reutemann 15 Jan '21

15 Jan '21

'Just ahead of its launch for commercial PC-like devices, an install image of Windows 10X for single screens has leaked, giving us an early peek at Microsoft's new OS. And yes, it's just like Chrome OS. From a report: Let's just get that out of the way. Microsoft has been working for years on a Chromebook competitor, but it has been largely unsuccessful. Windows 10 S, which was originally called Windows 10 Cloud, was Terry Myerson's approach, and that, of course, crashed and burned, in part because it looked identical to Windows 10 but couldn't run downloaded Windows 10 desktop applications. And now we have Windows 10X. Microsoft tried to hide its true intent with this product by pretending last year that it was aimed at a new generation of dual-display PCs, but the software giant really created 10X to compete with Chrome OS on inexpensive single-display PCs. So after failing to get its container-based Windows desktop application compatibility solution to work, Microsoft scaled back and repositioned Windows 10X as was originally intended: It will now ship only on new traditional PCs aimed at education and other commercial markets.' -- source: https://tech.slashdot.org/story/21/01/14/1657218 Wouldn't be surprised if they got bitten again by not having separate kernel/window manager architecture in Windows...

The Linux Foundation Now Offers a Suite of Open-Source Management Classes
by Peter Reutemann 14 Jan '21

14 Jan '21

'The Linux Foundation has new courses to help you manage open-source projects and technical staff within your organization. Steven J. Vaughan-Nichols writes via ZDNet: Previously, if you want to know how to run open-source well in your company, you had to work with OASIS Open or the TODO Group. Both are non-profit organizations supporting best open source and open standards practices. But, to work with either group, effectively, you already had to know a lot about open source. [...] This 7-module course series is designed to help executives, managers, software developers, and engineers understand the basic concepts for building effective open-source practices. It's also helpful to those in the C suite who want to set up effective open-source program management, including how to create an Open Source Program Office (OSPO). The program builds on the accumulated wisdom of many previous training modules on open-source best practices while adding fresh and updated content to explain all of the critical elements of working effectively with open source in enterprises.

Debian Discusses Vendoring -- Again
by Peter Reutemann 14 Jan '21

14 Jan '21

'Jake Edge, writing at LWN: The problems with "vendoring" in packages -- bundling dependencies rather than getting them from other packages -- seems to crop up frequently these days. We looked at Debian's concerns about packaging Kubernetes and its myriad of Go dependencies back in October. A more recent discussion in that distribution's community looks at another famously dependency-heavy ecosystem: JavaScript libraries from the npm repository. Even C-based ecosystems are not immune to the problem, as we saw with iproute2 and libbpf back in November; the discussion of vendoring seems likely to recur over the coming years. Many application projects, particularly those written in languages like JavaScript, PHP, and Go, tend to have a rather large pile of dependencies. These projects typically simply download specific versions of the needed dependencies at build time. This works well for fast-moving projects using collections of fast-moving libraries and frameworks, but it works rather less well for traditional Linux distributions. So distribution projects have been trying to figure out how best to incorporate these types of applications. This time around, Raphael Hertzog raised the issue with regard to the Greenbone Security Assistant (gsa), which provides a web front-end to the OpenVAS vulnerability scanner (which is now known as Greenbone Vulnerability Management or gvm). "the version currently in Debian no longer works with the latest gvm so we have to update it to the latest upstream release... but the latest upstream release has significant changes, in particular it now relies on yarn or npm from the node ecosystem to download all the node modules that it needs (and there are many of them, and there's no way that we will package them individually). The Debian policy forbids download during the build so we can't run the upstream build system as is." Hertzog suggested three possible solutions: collecting all of the dependencies into the Debian source package (though there would be problems creating the copyright file), moving the package to the contrib repository and adding a post-install step to download the dependencies, or removing gsa from Debian entirely. He is working on updating gsa as part of his work on Kali Linux, which is a Debian derivative that is focused on penetration testing and security auditing. Kali Linux does not have the same restrictions on downloading during builds that Debian has, so the Kali gsa package can simply use the upstream build process. He would prefer to keep gsa in Debian, "but there's only so much busy-work that I'm willing to do to achieve this goal". He wondered if it made more sense for Debian to consider relaxing its requirements. But Jonas Smedegaard offered another possible approach: analyzing what packages are needed by gsa and then either using existing Debian packages for those dependencies or creating new ones for those that are not available. Hertzog was convinced that wouldn't be done, but Smedegaard said that the JavaScript team is already working on that process for multiple projects.' -- source: https://linux.slashdot.org/story/21/01/13/1744228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

WhatsApp Clarifies It's Not Giving All Your Data To Facebook
by Peter Reutemann 14 Jan '21

14 Jan '21

'The Verge: WhatsApp has published a new FAQ page to its website outlining its stances on user privacy in response to widespread backlash over an upcoming privacy policy update. The core issue relates to WhatsApp's data-sharing procedures with Facebook, with many users concerned an updated privacy policy going into effect on February 8th will mandate sharing of sensitive profile information with WhatsApp's parent company. That isn't true -- the update has nothing to do with consumer chats or profile data, and instead the change is designed to outline how businesses who use WhatsApp for customer service may store logs of its chats on Facebook servers. That's something the company feels it is required to disclose in its privacy policy, which it's now doing after previewing the upcoming changes to business chats back in October. But a wave of misinformation on social media, not helped by Facebook's abysmal track record on privacy and its reputation for obfuscating changes to its various terms of service agreements, has resulted in a full-blown WhatsApp backlash that has users fleeing to competitors like Signal and Telegram. [...] WhatsApp executives, as well as Instagram chief Adam Mosseri and Facebook AR / VR head Andrew "Boz" Bosworth, are now trying to set the record straight, perhaps to little avail at this point. "We want to be clear that the policy update does not affect the privacy of your messages with friends or family in any way. Instead, this update includes changes related to messaging a business on WhatsApp, which is optional, and provides further transparency about how we collect and use data," the company writes on the new FAQ page. It also stresses in the FAQ that neither Facebook nor WhatsApp read users' message logs or listen to their calls, and that WhatsApp doesn't store user location data or share contact information with Facebook. (It's also worth noting that data sharing with Facebook is extremely limited for European users due to stronger user privacy protections in the EU.) WhatsApp chief Will Cathcart also took to Twitter a few days ago to post a thread (later shared by Bosworth in the tweet above) trying to cut through the confusion and explain what's actually going on. "With end-to-end encryption, we cannot see your private chats or calls and neither can Facebook. We're committed to this technology and committed to defending it globally," Cathcart wrote. "It's important for us to be clear this update describes business communication and does not change WhatsApp's data sharing practices with Facebook. It does not impact how people communicate privately with friends or family wherever they are in the world."

Hackers steal Mimecast certificate used to encrypt customers’ M365 traffic
by Peter Reutemann 13 Jan '21

13 Jan '21

'Email management provider Mimecast said that hackers have compromised a digital certificate it issued and used it to target select customers who use it to encrypt data they sent and received through the company’s cloud-based service. In a post published on Tuesday, the company said that the certificate was used by about 10 percent of its customer base, which—according to the company—numbers about 36,100. The “sophisticated threat actor” then likely used the certificate to target “a low single digit number” of customers using the certificate to encrypt Microsoft 365 data. Mimecast said it learned of the compromise from Microsoft. Certificate compromises allow hackers to read and modify encrypted data as it travels over the Internet. For that to happen, a hacker must first gain the ability to monitor the connection going into and out of a target’s network. Typically, certificate compromises require access to highly fortified storage devices that store private encryption keys. That access usually requires deep-level hacking or insider access. The Mimecast post didn’t describe what type of certificate was compromised, and a company spokesman declined to elaborate. This post, however, discusses how customers can use a certificate provided by Mimecast to connect their Microsoft 365 servers to the company’s service. Mimecast provides seven different certificates based on the geographic region of the customer.' -- source: https://arstechnica.com/information-technology/2021/01/mimecast-says-hacker… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Keeping Flash Player Going A Little Longer
by Lawrence D'Oliveiro 13 Jan '21

13 Jan '21

Adobe Flash Player has officially stopped working, since apparently Adobe included a logic bomb a few releases back with an expiry date in it <https://www.theregister.com/2021/01/12/flash_is_dead/>. However, for those who really, really need it, this article <https://charleswilkinson.co.uk/2021/01/12/how-to-use-flash-in-2021/> describes a workaround to re-enable it for certain sites (e.g. corporate intranet ones), by editing certain .cfg files. Those .cfg files don’t exist on a Linux installation -- not by default, anyway. However, doing a “strings” on libflashplayer.so finds (among other things) a reference to “/etc/adobe” and “/opt/adobe” directories. So perhaps you could create one of these and put files with the right names in it? Anyway, I’m just throwing this out there for anyone who wants to play with it. ;)

The Impractical but Indisputable Rise of Retrocomputing
by Peter Reutemann 13 Jan '21

13 Jan '21

'For all the personal technology introduced and popularized in 2020 -- upscale fitness bikes, at-home Covid tests, game consoles new and old -- the personal computer lands on the list with a bit of a thud. PCs lack the novelty of other gadgets, but they're practical, essential even, in a year when work, school and social life have come to rely heavily upon them. From a report: While modern, ever more efficient computers are selling better than they have in years, vintage computers -- impractical old devices in need of repairs and out-of-production parts -- are also in demand on sites like eBay. Collectors also flock to message boards, subreddits and Discord servers to buy, sell and trade parts. People are buying these PCs not necessarily for daily use, but for the satisfaction they get from rebuilding them. It's a trend one might chalk up to quarantine boredom, though it's been gaining traction for years. Retrocomputing, the hobby is called, is hardly just a way to pass the time. Instead, as enthusiasts see it, it's a means of communing with the past. "You get into this mind-set of what it must've been like to be somebody in the late '70s, having spent thousands of dollars on this thing that barely does anything more than a calculator," said Clint Basinger, 34, who runs the YouTube channel Lazy Game Reviews. (The devices do allow retrocomputers to make art and music using software unavailable on new computers and to play 8-bit games, but not much else beyond that.) "It's like a time machine to me," Mr. Basinger added. Before the pandemic, there were several vintage computing conventions located around the United States, to which collectors brought their computers to show off. Attendees bought and traded hardware at these events, as well as meet the friends they've made online.' -- source: https://it.slashdot.org/story/21/01/12/1910218 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

AMD Shows Off Impressive Ryzen 5000 Mobile Processors and 3rd Gen Epyc Server Chips
by Peter Reutemann 13 Jan '21

13 Jan '21

'Advanced Micro Devices showed off some impressive Ryzen 5000 mobile processors today and teased the performance of its 3rd Gen Epyc server chips. From a report: Those chips are aimed at keeping AMD's performance lead over its rival Intel in the mobile and server markets. AMD CEO Lisa Su showed off the new chips in a keynote speech at CES 2021, the online-only tech trade show. AMD is launching its Ryzen 5000 Series mobile processors for gaming laptops and thin-and-light notebooks. These eight-core x86 chips are built with a 7-nanometer manufacturing process (where the circuits are 7 billionths of a meter apart). They are also based on the Zen3 design for processor cores, which can process instructions 19% faster per clock cycle than Zen2 cores. The H-Series focuses on top performance in laptops for gamers and content creators, while the U-Series focuses on thin-and-light notebooks with great battery life. The chips have four to eight cores and they range in power consumption from 15 watts to 45 watts. AMD said the 5000 Series will be available in PCs in February, and we'll see more than 150 systems using it.

Firefox To Block Backspace Key From Working as 'Back' Button

From a report: The change is currently active in the Firefox Nightly version and is expected to go live in Firefox 86, scheduled to be released next month, in late February 2021. The removal of the Backspace key as a navigational element didn't come out of the blue. It was first proposed back in July 2014, in a bug report opened on Mozilla's bug tracker. At the time, Mozilla engineers argued that many users who press the Backspace key don't always mean to navigate to the previous page (the equivalent of pressing the Back button).' -- source: https://news.slashdot.org/story/21/01/11/1551224 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Rediscovering RISC-V: Apple M1 Sparks Renewed Interest in Non-x86 Architecture
by Peter Reutemann 11 Jan '21

11 Jan '21

'"With the runaway success of the new ARM-based M1 Macs, non-x86 architectures are getting their closeup," explains a new article at ZDNet. "RISC-V is getting the most attention from system designers looking to horn-in on Apple's recipe for high performance. Here's why..." RISC-V is, like x86 and ARM, an instruction set architecture (ISA). Unlike x86 and ARM, it is a free and open standard that anyone can use without getting locked into someone else's processor designs or paying costly license fees... Reaching the end of Moore's Law, we can't just cram more transistors on a chip. Instead, as Apple's A and M series processors show, adding specialized co-processors — for codecs, encryption, AI — to fast general-purpose RISC CPUs can offer stunning application performance and power efficiency. But a proprietary ISA, like ARM, is expensive. Worse, they typically only allow you to use that ISA's hardware designs, unless, of course, you're one of the large companies — like Apple — that can afford a top-tier license and a design team to exploit it. A canned design means architects can't specify tweaks that cut costs and improve performance. An open and free ISA, like RISC-V, eliminates a lot of this cost, giving small companies the ability to optimize their hardware for their applications. As we move intelligence into ever more cost-sensitive applications, using processors that cost a dollar or less, the need for application and cost-optimized processors is greater than ever... While open operating systems, like Linux, get a lot of attention, ISAs are an even longer-lived foundational technology. The x86 ISA dates back 50 years and today exists as a layer that gets translated to a simpler — and faster — underlying hardware architecture. (I suspect this fact is key to the success of the macOS Rosetta 2 translation from x86 code to Apple's M1 code.) Of course, an open ISA is only part of the solution. Free standard hardware designs — with tools to design more — and smart compilers to generate optimized code are vital. That larger project is what Berkeley's Adept Lab is working on. As computing continues to permeate civilization, the cost of sub-optimal infrastructure will continue to rise. Optimizing for efficiency, long-life, and broad application is vital for humanity's progress in a cyber-enabled world. One RISC-V feature highlighted by the article: 128-bit addressing (in addition to 32 and 64 bit).' -- source: https://hardware.slashdot.org/story/21/01/10/2020208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Wasmer 1.0 Can Run WebAssembly 'Universal Binaries' on Linux, MacOS, Windows, Android, and iOS
by Peter Reutemann 11 Jan '21

11 Jan '21

'The WebAssembly portable binary format will now have wider support from Wasmer, the server-side runtime which "allows universal binaries compiled from C++, Rust, Go, Python, and other languages to run on different operating systems and in web browsers without modification," reports InfoWorld: Wasmer can run lightweight containers based on WebAssembly on a variety of platforms — Linux, MacOS, Windows, Android, iOS — from the desktop to the cloud to IoT and mobile devices, while also allowing these containers to be embedded in any programming language. The Wasmer runtime also is able to run the Nginx web server and other WebAssembly modules... Wasmer was introduced in December 2018, with the stated goal of doing for WebAssembly what JavaScript did for Node.js: establish it server-side. By leveraging Wasmer for containerization, developers can create universal binaries that work anywhere without modification, including on Linux, MacOS, and Windows as well as web browsers. WebAssembly automatically sandboxes applications by default for secure execution, shielding the host environment from malicious code, bugs, and vulnerabilities in the software being run. Wasmer 1.0 reached "general availability status" with its release on January 5, and its developers are now claiming "out of this world" runtime and compiler performance. "We believe that WebAssembly will be a crucial component for the future of software execution and containerization (not only inside the browser but also outside)."' -- source: https://news.slashdot.org/story/21/01/10/0242244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New Side-Channel Attack Can Recover Encryption Keys From Google Titan Security Keys
by Peter Reutemann 09 Jan '21

09 Jan '21

'A duo of French security researchers has discovered a vulnerability impacting chips used inside Google Titan and YubiKey hardware security keys. From a report: The vulnerability allows threat actors to recover the primary encryption key used by the hardware security key to generate cryptographic tokens for two-factor authentication (2FA) operations. Once obtained, the two security researchers say the encryption key, an ECDSA private key, would allow threat actors to clone Titan, YubiKey, and other keys to bypass 2FA procedures. However, while the attack sounds disastrous for Google and Yubico security key owners, its severity is not what it seems. In a 60-page PDF report, Victor Lomne and Thomas Roche, researchers with Montpellier-based NinjaLab, explain the intricacies of the attack, also tracked as CVE-2021-3011. For starters, the attack won't work remotely against a device, over the internet, or over a local network. To exploit any Google Titan or Yubico security key, an attacker would first need to get their hands on a security key in the first place.' -- source: https://tech.slashdot.org/story/21/01/08/1814254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A Crypto-Mining Botnet Is Now Stealing Docker and AWS Credentials
by Peter Reutemann 09 Jan '21

09 Jan '21

'ZDNet: Analysts from security firm Trend Micro said in a report today that they've spotted a malware botnet that collects and steals Docker and AWS credentials. Researchers have linked the botnet to a cybercrime operation known as TeamTNT; a group first spotted over the 2020 summer installing cryptocurrency-mining malware on misconfigured container platforms. Initial reports at the time said that TeamTNT was breaching container platforms by looking for Docker systems that were exposing their management API port online without a password. Researchers said the TeamTNT group would access exposed Docker containers, install a crypto-mining malware, but also steal credentials for Amazon Web Services (AWS) servers in order to pivot to a company's other IT systems to infect even more servers and deploy more crypto-miners. At the time, researchers said that TeamTNT was the first crypto-mining botnet that implemented a feature dedicated to collecting and stealing AWS credentials. But in a report today, Trend Micro researchers said that the TeamTNT gang's malware code had received considerable updates since it was first spotted last summer. TeamTNT has now also added a feature to collect Docker API credentials, on top of the AWS creds-stealing code. This feature is most likely used on container platforms where the botnet infects hosts using other entry points than its original Docker API port scanning feature.' -- source: https://it.slashdot.org/story/21/01/08/2132205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

UK Watchdog Begins Investigating Nvidia's $40 Billion Takeover of Arm
by Peter Reutemann 07 Jan '21

'Britain's competition watchdog has launched an investigation into the $40 billion takeover of the UK-based chip designer Arm by the US company Nvidia. From a report: The Competition and Markets Authority (CMA) has called for interested parties to submit views on the contentious deal before the launch of a formal investigation later this year. Arm Holdings, which employs 6,500 staff including 3,000 in the UK, is a global leader in designing chips for smartphones, computers and tablets. California-based Nvidia, a graphics chip specialist, announced its plan to buy the British tech group from Japan's SoftBank in September. SoftBank had acquired Arm for $32 billion in 2016, when the Japanese company took advantage of the fall in value of the pound after the Brexit vote. Arm is based in Cambridge but has operations in a number of UK towns and cities, including Manchester, Belfast and Warwick. Its chief executive, Simon Segars, acknowledged at the time of the Nvidia deal that it could take up to 18 months to win approval from regulators around the world.' -- source: https://news.slashdot.org/story/21/01/06/1945224 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The researcher who discovered the disclosure vulnerability and privately reported it to Telegram developers said they have no plans to fix it. The problem stems from a feature called People Nearby. By default, it’s turned off. When users enable it, their geographic distance is shown to other people who have it turned on and are in (or are spoofing) the same geographic region. When People Nearby is used as designed, it’s a useful feature with few if any privacy concerns. After all, a notification that someone is 1 kilometer or 600 meters away still leaves stalkers guessing where, precisely, you are. Independent researcher Ahmed Hassan, however, has shown how the feature can be abused to divulge exactly where you are. Using readily available software and a rooted Android device, he’s able to spoof the location his device reports to Telegram servers. By using just three different locations and measuring the corresponding distance reported by People Nearby, he is able to pinpoint a user’s precise location.' -- source: https://arstechnica.com/information-technology/2021/01/telegram-feature-exp… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Cryptocurrency stealer for Windows, macOS, and Linux went undetected for a year
by Peter Reutemann 06 Jan '21

06 Jan '21

'Soaring cryptocurrency valuations have broken record after record over the past few years, turning people with once-modest holdings into overnight millionaires. One determined ring of criminals has tried to join the party using a wide-ranging operation that for the past 12 months has used a full-fledged marketing campaign to push custom-made malware written from scratch for Windows, macOS, and Linux devices. The operation, which has been active since at least January 2020, has spared no effort in stealing the wallet addresses of unwitting cryptocurrency holders, according to a report published by security firm Intezer. The scheme includes three separate trojanized apps, each of which runs on Windows, macOS, and Linux. It also relies on a network of fake companies, websites, and social media profiles to win the confidence of potential victims. The apps pose as benign software that’s useful to cryptocurrency holders. Hidden inside is a remote access trojan that was written from scratch. Once an app is installed, ElectroRAT—as Intezer has dubbed the backdoor—then allows the crooks behind the operation to log keystrokes, take screenshots, upload, download, and install files, and execute commands on infected machines. In a testament to their stealth, the fake cryptocurrency apps went undetected by all major antivirus products.' -- source: https://arstechnica.com/information-technology/2021/01/cryptocurrency-steal… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hackers are exploiting a backdoor built into Zyxel devices. Are you patched?
by Peter Reutemann 06 Jan '21

'Hackers are attempting to exploit a recently discovered backdoor built into multiple Zyxel device models that hundreds of thousands of individuals and businesses use as VPNs, firewalls, and wireless access points. The backdoor comes in the form of an undocumented user account with full administrative rights that’s hardcoded into the device firmware, a researcher from Netherlands-based security firm Eye Control recently reported.

Linus Torvalds Rails At Intel For 'Killing' the ECC Industry
by Peter Reutemann 06 Jan '21

06 Jan '21

'The Register: Linux creator Linus Torvalds has accused Intel of preventing widespread use of error-correcting memory and being "instrumental in killing the whole ECC industry with its horribly bad market segmentation." ECC stands for error-correcting code. ECC memory uses additional parity bits to verify that the data read from memory is the same as the data that was written. Without this check, memory is vulnerable to occasional corruption where a bit is flipped spontaneously, for example, by background radiation. Memory can also be attacked using a technique called Rowhammer, where rapid repeated reads of the same memory locations can cause adjacent locations to change their state. ECC memory solves these problems and has been available for over 50 years yet most personal computers do not use it. Cost is a factor but what riles Torvalds is that Intel has made ECC support a feature of its Xeon range, aimed at servers and high-end workstations, and does not support it in other ranges such as the Core series. The topic came up in a discussion about AMD's new Zen 3 Ryzen 9 5000 series processors on the Real World Tech forum site. AMD has semi-official ECC support in most of its processors. "I don't really see AMD's unofficial ECC support being a big deal," said an unwary contributor. "ECC absolutely matters," retorted Torvalds. "Intel has been detrimental to the whole industry and to users because of their bad and misguided policies wrt ECC. Seriously. And if you don't believe me, then just look at multiple generations of rowhammer, where each time Intel and memory manufacturers bleated about how it's going to be fixed next time... And yes, that was -- again -- entirely about the misguided and arse-backwards policy of 'consumers don't need ECC', which made the market for ECC memory go away." The accusation is significant particularly at a time when security issues are high on the agenda. The suggestion is that Intel's marketing decisions have held back adoption of a technology that makes users more secure -- though rowhammer is only one of many potential attack mechanisms -- as well as making PCs more stable. "The arguments against ECC were always complete and utter garbage. Now even the memory manufacturers are starting to do ECC internally because they finally owned up to the fact that they absolutely have to," said Torvalds. Torvalds said that Xeon prices deterred usage. "I used to look at the Xeon CPU's, and I could never really make the math work. The Intel math was basically that you get twice the CPU for five times the price. So for my personal workstations, I ended up using Intel consumer CPU's." Prices, he said, dropped last year "because of Ryzen and Threadripper... but it was a 'too little, much too late' situation." By way of mitigation, he added that "apart from their ECC stance I was perfectly happy with [Intel's] consumer offerings."' -- source: https://linux.slashdot.org/story/21/01/05/0318254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Splinternet Is Coming
by Lawrence D'Oliveiro 05 Jan '21

05 Jan '21

Countries like Russia, Iran and China are exerting more and more control over how Internet traffic crosses their borders. They are moving towards--or in some cases have already achieved--the ability to completely cut themselves off from the wider Internet and continue functioning with some autonomy. Also seems like China is promoting new protocol standards that will make this process even easier. I also learned of the existence of an organization called “Internet Sans Frontières”, which you would think is a tautology. But for how much longer? <https://www.theregister.com/2021/01/04/welcome_to_the_splinternet/>

Malware Uses WiFi BSSID for Victim Identification
by Peter Reutemann 05 Jan '21

05 Jan '21

'Malware operators who want to know the location of the victims they infect usually rely on a simple technique where they grab the victim's IP address and check it against an IP-to-geo database like MaxMind's GeoIP to get a victim's approximate geographical location. While the technique isn't very accurate, it is still the most reliable method of determining a user's actual physical location based on data found on their computer. However, in a blog post last month, Xavier Mertens, a security researcher with the SANS Internet Storm Center, said he discovered a new malware strain that is using a second technique on top of the first. This second technique relies on grabbing the infected user's BSSID. Known as a "Basic Service Set Identifier," the BSSID is basically the MAC physical address of the wireless router or access point the user is using to connect via WiFi. You can see the BSSID on Windows systems by running the command: netsh wlan show interfaces | find "BSSID" Mertens said the malware he discovered was collecting the BSSID and then checking it against a free BSSID-to-geo database maintained by Alexander Mylnikov.' -- source: https://it.slashdot.org/story/21/01/04/2042204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Are We Experiencing a Great Software Stagnation?
by Peter Reutemann 04 Jan '21

04 Jan '21

'Long-time programmer/researcher/former MIT research fellow Jonathan Edwards writes a blog called "Alarming Development: Dispatches from the User Liberation Front." He began the new year by arguing that software "is eating the world. But progress in software technology itself largely stalled around 1996." Slashdot reader tonique summarizes Edwards' argument: In 1996 there were "LISP, Algol, Basic, APL, Unix, C, Oracle, Smalltalk, Windows, C++, LabView, HyperCard, Mathematica, Haskell, WWW, Python, Mosaic, Java, JavaScript, Ruby, Flash, Postgress [sic]". After that we're supposed to have achieved "IntelliJ, Eclipse, ASP, Spring, Rails, Scala, AWS, Clojure, Heroku, V8, Go, React, Docker, Kubernetes, Wasm". Edwards's main thesis is that the Internet boom around 1996 caused this slowdown because programmers could get rich quick. Then smart and ambitious people moved into Silicon Valley, and founded startups. But you can't do research at a startup due to time and money constraints. Today only "megacorps" like Google, Facebook, Apple and Microsoft are supposedly able to do relevant research because of their vast resources. Computer science wouldn't help, either, because "most of our software technology was built in companies" and because computer science "strongly disincentivizes risky long-range research". Further, according to Edwards, the aversion to risk and "hyper-professionalization of Computer Science" is part of a larger and worrisome trend throughout the whole field and all of western civilisation. Edwards' blog post argues that since 1996 "almost everything has been cleverly repackaging and re-engineering prior inventions. Or adding leaky layers to partially paper over problems below. Nothing is obsoleted, and the teetering stack grows ever higher..." "[M]aybe I'm imagining things. Maybe the reason progress stopped in 1996 is that we invented everything. Maybe there are no more radical breakthroughs possible, and all that's left is to tinker around the edges. This is as good as it gets: a 50 year old OS, 30 year old text editors, and 25 year old languages. "Bullshit. No technology has ever been permanent. We've just lost the will to improve."' -- source: https://developers.slashdot.org/story/21/01/03/0010225 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Is Working On a Firefox Design Refresh
by Peter Reutemann 04 Jan '21

04 Jan '21

'Mozilla is "investigating" a design refresh for its Firefox browser. Ghacks reports that the refresh is referred to internally as "Photon." Information about the design refresh is limited at this point in time. Mozilla created a meta bug on Bugzilla as a reference to keep track of the changes. While there are not any mockups or screenshots posted on the site, the names of the bugs provide information on the elements that will get a refresh. These are: - The Firefox address bar and tabs bar. - The main Firefox menu. - Infobars. - Doorhangers. - Context Menus. - Modals. Most user interface elements are listed in the meta bug. Mozilla plans to release the new design in Firefox 89; the browser is scheduled for a mid-2021 release. Its release date is set to May 18, 2021... [Developer/Firefox extension author] Sören Hentzschel revealed that he saw some of the Firefox Proton mockups... He notes that Firefox will look more modern when the designs land and that Mozilla plans to introduce useful improvements, especially in regards to the user experience. Hentzschel mentions two examples of potential improvements to the user experience: a mockup that displays vertical tabs in a compact mode, and another that shows the grouping of tabs on the tab bar.' -- source: https://news.slashdot.org/story/21/01/03/0516247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Blender At Cannes
by Lawrence D'Oliveiro 01 Jan '21

01 Jan '21

Just found out about this French-made animation <https://en.wikipedia.org/wiki/I_Lost_My_Body> which was shown at Cannes 2019, and won the “Nespresso Grand Prize”. I mention it because its trivia page at IMDb <https://www.imdb.com/title/tt9806192/trivia> says “Created using the free open-source software Blender”. Note that it is not a typical 3D graphics animation: it is (mostly) drawn/rendered in a style that looks like traditional 2D cel animation. Blender has a feature called the “Grease Pencil” that lets you combine 3D and 2D-style art into the same workflow. This goes beyond simple “toon shaders” as found in other 3D software, to actually let you draw brushstrokes in 3D space, as geometric objects in their own right.

Should Intel Stop Making Chips?
by Lawrence D'Oliveiro 01 Jan '21

01 Jan '21

Intel has suffered more than one misstep in its recent attempts to move to more advanced chip-fabrication technologies. Performance-wise, AMD has been eating its breakfast. RISC-based alternative architectures like ARM and RISC-V are eating into the x86 market. Now an investor fund <https://arstechnica.com/gadgets/2020/12/activist-hedge-fund-advises-intel-t…> is suggesting that Intel outsource its chip-making facilities altogether (like AMD did years ago). This part was news to me: “Intel has lost some $60 billion in market value over the past year...”. According to Yahoo Finance <https://finance.yahoo.com/quote/INTC/>, its current market cap is just a bit over $200 billion. So that $60 billion represents a huge drop in its share price.

Mastodon Versus Gab
by Lawrence D'Oliveiro 29 Dec '20

29 Dec '20

(OK, this is an old article, but I just noticed it.) Mastodon is not a social network, but a “federation” of social networks. It is built on open-source protocols and software, which you can use to set up your own social-network node. You can then become part of the “fediverse” by associating with other Mastodon nodes, allowing users of one to interact with users of another. What is allowed on a node is entirely up the policies of the node admins. The Fediverse is intentionally decentralized, and admins of one node do not have the power to control what users do on another node. Contrast this with traditional social-networking sites like Facebook and Twitter, each of which is controlled by a single company. Naturally, such autonomy is a double-edged sword. So what do you do when the neo-Nazis move in? Gab, home of those who have promoted violence against various groups based on ethnicity, sexuality etc, is now a Mastodon node. How is the rest of the Fediverse dealing with them? The answer seems to be: you can’t stop them operating, but you can shun them. <https://www.theverge.com/2019/7/12/20691957/mastodon-decentralized-social-n…>

Yes, a brand new port to the game console that launched more than two decades ago. Open-source developer Lauri Kasanen who has contributed to Mesa and the Linux graphics stack took to developing a new Nintendo 64 port and announced it this Christmas day. This isn't the first time Linux has been ported to the N64 but prior attempts weren't aimed at potentially upstreaming it into the mainline Linux kernel... This fresh port to the N64 was pursued in part to help port emulators and frame-buffer or console games.

Let’s Encrypt comes up with workaround for abandonware Android devices
by Peter Reutemann 29 Dec '20

29 Dec '20

'Things were touch-and-go for a while, but it looks like Let's Encrypt's transition to a standalone certificate authority (CA) isn't going to break a ton of old Android phones. This was a serious concern earlier due to an expiring root certificate, but Let's Encrypt has come up with a workaround. Let's Encrypt is a fairly new certificate authority, but it's also one of the world's leading. The service was a major player in the push to make the entire Web run over HTTPS, and as a free, open issuing authority, it went from zero certs to one billion certs in just four years. For regular users, the list of trusted CAs is usually issued by your operating system or browser vendor, so any new CA has a long rollout that involves getting added to the list of trusted CAs by every OS and browser on Earth as well as getting updates to every user. To get up and running quickly, Let's Encrypt got a cross-signature from an established CA, IdenTrust, so any browser or OS that trusted IdenTrust could now trust Let's Encrypt, and the service could start issuing useful certs. When it launched in 2016, Let's Encrypt also issued its own root certificate ("ISRG Root X1") and applied for it to be trusted by the major software platforms, most of which accepted it sometime that year. Now, several years later, with IdenTrust's "DST Root X3" certificate set to expire in September 2021, the time has come for Let's Encrypt to stand on its own and rely on its own root certificate. Since this was submitted four years ago, surely every Web-capable OS currently in use has gotten an update with Let's Encrypt's cert, right? That's true of every mainstream OS except for one. Sitting in the corner of the room, wearing a dunce cap, is Android, the world's only major consumer operating system that can't be centrally updated by its creator. Believe it or not, there are still quite a lot of people running a version of Android that hasn't been updated in four years. Let's Encrypt says it was added to Android's CA store in version 7.1.1 (released December 2016) and, according to Google's official stats, 33.8 percent of active Android users are on a version older than that. Given Android's 2.5 billion strong monthly active user base, that's 845 million people who have a root store frozen in 2016. Oh no.' -- source: https://arstechnica.com/gadgets/2020/12/lets-encrypt-comes-up-with-workarou… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Websites That Won’t Let Go
by Lawrence D'Oliveiro 26 Dec '20

26 Dec '20

A friend asked me for help, saying some kind of “gambling app” had managed to attach itself to his Android phone, and kept popping up all the time. I figured he had been tricked into installing something, and we would probably have to track down the app, which likely had some innocuous name to obscure its purpose. Or possibly even worse, it had managed to take advantage of some vulnerability in his OS version to hide itself. Turned out it was a bit simpler than that. It was a website he had visited in Chrome (most likely following a link from an ad or something), which had an interesting technique to prevent him from getting away: it kept pestering him to allow it to access his location data. The trick was, it had maybe a hundred (maybe more) different site names of the form “«nn».example.com”, so when you blocked one, it would simply ask again, the request coming from a different number for «nn». The expectation obviously was that the user would eventually give up and allow one of these sites access. I was able to close the offending tab, but on quitting and restarting Chrome, it would come back. I figured out that his Chrome setting was to restore the last-visited page(s) when Chrome was restarted, which was why this page kept coming up. So I just turned off that setting. I thought maybe there was some deeper malware that would just bring the problem back when that setting was restored, and that he should consult somebody expert on more recent versions of Android to see about a permanent fix. But he suggested re-enabling that setting, just to confirm the problem was still there. And I did. And it wasn’t! So there was no obvious sign of any malware installation, it was just the website itself, exploiting a quirk of browser behaviour, to gain a lock on the user and blackmail them into giving up their location data.

Citrix Devices Are Being Abused as DDoS Attack Vectors

From a report: While details about the attackers are still unknown, victims of these Citrix-based DDoS attacks have mostly included online gaming services, such as Steam and Xbox, sources have told ZDNet earlier today. The first of these attacks have been detected last week and documented by German IT systems administrator Marco Hofmann. Hofmann tracked the issue to the DTLS interface on Citrix ADC devices. DTLS, or Datagram Transport Layer Security, is a more version of the TLS protocol implemented on the stream-friendly UDP transfer protocol, rather than the more reliable TCP. Just like all UDP-based protocols, DTLS is spoofable and can be used as a DDoS amplification vector.

Up To 3 Million Devices Infected By Malware-Laced Chrome and Edge Add-Ons
by Peter Reutemann 17 Dec '20

17 Dec '20

'As many as 3 million people have been infected by Chrome and Edge browser extensions that steal personal data and redirect users to ad or phishing sites, a security firm said on Wednesday. Ars Technica reports: In all, researchers from Prague-based Avast said they found 28 extensions for the Google Chrome and Microsoft Edge browsers that contained malware. The add-ons billed themselves as a way to download pictures, videos, or other content from sites including Facebook, Instagram, Vimeo, and Spotify. At the time this post went live, some, but not all, of the malicious extensions remained available for download from Google and Microsoft. Avast researchers found malicious code in the JavaScript-based extensions that allows them to download malware onto an infected computer. In a post, the researchers wrote: "Users have also reported that these extensions are manipulating their internet experience and redirecting them to other websites. Anytime a user clicks on a link, the extensions send information about the click to the attacker's control server, which can optionally send a command to redirect the victim from the real link target to a new hijacked URL before later redirecting them to the actual website they wanted to visit. User's privacy is compromised by this procedure since a log of all clicks is being sent to these third party intermediary websites. The actors also exfiltrate and collect the user's birth dates, email addresses, and device information, including first sign in time, last login time, name of the device, operating system, used browser and its version, even IP addresses (which could be used to find the approximate geographical location history of the user)." The researchers don't yet know if the extensions came with the malicious code preinstalled or if the developers waited for the extensions to gain a critical mass of users and only then pushed a malicious update. It's also possible that legitimate developers created the add-ons and then unknowingly sold them to someone who intended to use them maliciously. [...] The list Avast provides in its blog post includes links to download locations for both Chrome and Edge. Anyone who has downloaded one of these add-ons should remove it immediately and run a virus scan.

Google Will Officially Support Running Chrome OS On Old PCs
by Peter Reutemann 17 Dec '20

17 Dec '20

'This week, Google acquired a company called Neverware that allows users to turn their old PCs and Macs into a Chromebook with its CloudReady software. Now, Google is planning to make CloudReady into an official Chrome OS release. Engadget reports: When that happens, Neverware says its existing users will be able to seamlessly upgrade to the updated software. Moreover, once that transition is complete, Google will support CloudReady in the same way that it currently does Chrome OS. In the immediate future, Neverware says it's business as usual. The Home Edition of CloudReady isn't changing, and the company says it's committed to supporting its existing education and enterprise customers. Moreover, there's no plan to change pricing at the moment, and Google will honor any current multi-year licenses. Not only does this acquisition make a lot of sense from Google's perspective, but it's hard to see a downside for CloudReady users. The fact the operating system wasn't officially supported by Google was one of the few downsides to the software. It meant you couldn't install Android apps on CloudReady devices, even though it's based on Chromium OS. With this acquisition, support for Android apps becomes much more likely. Direct support from Google will also make the software more appealing to schools and businesses since they can get help directly from the company if they have any technical issues.' -- source: https://tech.slashdot.org/story/20/12/16/219202 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Australia Sues Facebook Over Its Use of Onavo To Snoop
by Peter Reutemann 17 Dec '20

17 Dec '20

'Australia's Competition and Consumer Commission (ACCC) is suing Facebook over its use, in 2016 and 2017, of the Onavo VPN app to spy on users for commercial purposes. From a report: The ACCC's case accuses Facebook of false, misleading or deceptive conduct toward thousands of Australian consumers, after it had promoted the Onavo Protect app -- saying it would keep users personal activity data private, protected and secret and not use it for any other purpose, when it was being used to gather data to help Facebook's business. "Through Onavo Protect, Facebook was collecting and using the very detailed and valuable personal activity data of thousands of Australian consumers for its own commercial purposes, which we believe is completely contrary to the promise of protection, secrecy and privacy that was central to Facebook's promotion of this app," said ACCC chair Rod Sims in a statement. "Consumers often use VPN services because they care about their online privacy, and that is what this Facebook product claimed to offer. In fact, Onavo Protect channelled significant volumes of their personal activity data straight back to Facebook."' -- source: https://yro.slashdot.org/story/20/12/16/1652247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Gmail Is Broken Right Now, One Day After a Massive Outage
by Peter Reutemann 16 Dec '20

16 Dec '20

'TechCrunch: While it doesn't appear to be completely down like it was yesterday morning, we're hearing many reports from Gmail users that the email service is having major issues right now. Some users are reporting that Gmail is particularly slow, while others are reporting constant error messages. One TechCrunch writer, meanwhile, noticed that emails he was sending to Gmail accounts appeared to immediately bounce, with Gmail's server responding with an error reading "550-5.1.1 The email account that you tried to reach does not exist." Google confirms the issues on its services dashboard, writing at 1:30 PM Pacific that they're impacting a "significant" number of users: "We're aware of a problem with Gmail affecting a significant subset of users. The affected users are able to access Gmail, but are seeing error messages, high latency, and/or other unexpected behavior." In a second update at 2:30 PM, Google says its teams are "continuing to investigate this issue"; as of 3:30 PM, the company says it expects the issues to be fixed by 4:00 PM while noting that time may change. Google says the problems have been resolved, although encrypted email service ProtonMail tweets that the email bouncing issue is widespread, with many emails sent to Gmail users bouncing permanently.' -- source: https://tech.slashdot.org/story/20/12/16/0231237 Yeah, I'm one of those affected by this outage. Haven't been receiving a bunch of emails (but really random, some come through whilst others don't)... In Gmail's defence, I haven't had many problems over all these years!

Microsoft and Industry Partners Seize Key Domain Used In SolarWinds Hack
by Peter Reutemann 16 Dec '20

16 Dec '20

'ZDNet: Microsoft and a coalition of tech companies have intervened today to seize and sinkhole a domain that played a central role in the SolarWinds hack, ZDNet has learned from sources familiar with the matter. The domain in question is avsvmcloud[.]com, which served as command and control (C&C) server for malware delivered to around 18,000 SolarWinds customers via a trojanized update for the company's Orion app. SolarWinds Orion updates versions 2019.4 through 2020.2.1, released between March 2020 and June 2020, contained a strain of malware named SUNBURST (also known as Solorigate). Once installed on a computer, the malware would sit dormant for 12 to 14 days and then ping a subdomain of avsvmcloud[.]com. According to analysis from security firm FireEye, the C&C domain would reply with a DNS response that contained a CNAME field with information on another domain from where the SUNBURST malware would obtain further instructions and additional payloads to execute on an infected company's network. Earlier today, a coalition of tech companies seized and sinkholed avsvmcloud[.]com, transferring the domain into Microsoft's possession. Sources familiar with today's actions described the takedown as "protective work" done to prevent the threat actor behind the SolarWinds hack from delivering new orders to infected computers.' -- source: https://it.slashdot.org/story/20/12/15/2117255 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

CloudLinux To Invest More Than a Million Dollars a Year Into CentOS Clone
by Peter Reutemann 16 Dec '20

16 Dec '20

'ZDNet: When Red Hat, CentOS's Linux parent company, announced it was "shifting focus from CentOS Linux, the rebuild of Red Hat Enterprise Linux (RHEL), to CentOS Stream, which tracks just ahead of a current RHEL release," it lost a lot of friends. CentOS co-founder, Gregory Kurtzer, immediately announced he'd create his own RHEL clone and CentOS replacement: Rocky Linux. He wasn't the only one. CloudLinux also proclaimed it would create a new CentOS clone Lenix. And, CloudLinux will be putting over a million dollars a year behind it. Why? Igor Seletskiy, CloudLinux CEO and founder, explained, "Red Hat's announcement has left users looking for an alternative with all that CentOS provides and without the disruption of having to move to alternative distributions. We promise to dedicate the resources required to Project Lenix that will ensure impartiality and a not-for-profit community initiative. CloudLinux already has the assets, infrastructure, and experience to carry out the mission, and we promise to be open about the process of developing Project Lenix." [...] Project Lenix will be a free, open-source, community-driven, 1:1 binary compatible fork of RHEL 8 (and future releases). For CentOS users, the company promises Lenix will provide an uninterrupted way to convert existing CentOS servers with absolutely zero downtime or need to reinstall anything. The company even claims you'll be able to port entire CentOS server fleets with a single command with no reinstallation or reboots required. That's a bold claim. But CloudLinux already does that trick with its commercial Linux distribution. If the company says it can do it, I think it can. Lenix is only a placeholder name, notes ZDNet. "[A] yet to be formed governing board will decide on a permanent name for the distribution. If all goes well, the first software release will appear in the first quarter of 2021."' -- source: https://linux.slashdot.org/story/20/12/15/0218245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Group that hacked SolarWinds can bypass MFA account protections
by Peter Reutemann 15 Dec '20

15 Dec '20

'The hackers behind the supply chain attack that compromised public and private organizations have devised a clever way to bypass multi-factor-authentication systems protecting the networks they target. Researchers from security firm Volexity said on Monday that it had encountered the same attackers in late 2019 and early 2020 as they penetrated deep inside of a think tank organization no fewer than three times. During one of the intrusions, Volexity researchers noticed the hackers using a novel technique to bypass MFA protections provided by Duo. After having gained administrator privileges on the infected network, the hackers used those unfettered rights to steal a Duo secret known as an akey from a server running Outlook Web App, which enterprises use to provide account authentication for various network services.' -- source: https://arstechnica.com/information-technology/2020/12/solarwinds-hackers-h… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Israeli Spy Tech Firm Says It Can Break Into Signal App
by Peter Reutemann 15 Dec '20

15 Dec '20

'Last Thursday, Israeli phone-hacking firm Cellebrite said in a blog post that it can now break into Signal, an encrypted app considered safe from external snooping. Haaretz reports: Cellebrite's flagship product is the UFED (Universal Forensic Extraction Device), a system that allows authorities to unlock and access the data of any phone in their possession. Another product it offers is the Physical Analyzer, which helps organize and process data lifted from the phone. Last Thursday, the company announced that the analyzer has now been updated with a new capability, developed by the firm, that allows clients to decode information and data from Signal. Signal, owned by the Signal Technology Foundation, uses a special open source encryption system called Signal Protocol, which was thought to make it nigh-on impossible for a third party to break into a conversation or access data being shared on the platform. It does so by employing what's called "end-to-end encryption." According to Cellebrite's announcement last week, "Law enforcement agencies are seeing a rapid rise in the adoption of highly encrypted apps like Signal, which incorporate capabilities like image blurring to stop police from reviewing data. "Criminals are using this application to communicate, send attachments, and making [sic] illegal deals that they want to keep discrete [sic] and out of sight from law enforcement," the blog post added. Despite support for the app's encryption capabilities, Cellebrite noted that "Signal is an encrypted communication application designed to keep sent messages and attachments as safe as possible from 3rd-party programs. "Cellebrite Physical Analyzer now allows lawful access to Signal app data. At Cellebrite, we work tirelessly to empower investigators in the public and private sector to find new ways to accelerate justice, protect communities, and save lives." In an earlier, now deleted, version of the blog post, the company went as far as to say: "Decrypting Signal messages and attachments was not an easy task. It required extensive research on many different fronts to create new capabilities from scratch. At Cellebrite, however, finding new ways to help those who make our world a safer place is what we're dedicated to doing every day." The initial post, which was stored on the Internet Archive, also included a detailed explanation of how Cellebrite "cracked the code" by reviewing Signal's own open source protocol and using it against it. The company noted in the deleted blog post that "because [Signal] encrypts virtually all its metadata to protect its users, efforts have been put forward by legal authorities to require developers of encrypted software to enable a 'backdoor' that makes it possible for them to access people's data. Until such agreements are reached, Cellebrite continues to work diligently with law enforcement to enable agencies to decrypt and decode data from the Signal app."' -- source: https://it.slashdot.org/story/20/12/14/2241230 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

~18,000 organizations downloaded backdoor planted by Cozy Bear hackers
by Peter Reutemann 15 Dec '20

15 Dec '20

'About 18,000 organizations around the world downloaded network management tools that contained a backdoor that spies believed to be backed by the Russian government could use to install additional malware that stole sensitive data, the tools provider, SolarWinds, said on Monday. The disclosure from Austin, Texas-based software maker SolarWinds, came a day after the US government revealed a major security breach hitting federal agencies and private companies. The US Departments of Treasury, Commerce, and Homeland Security departments were among the federal agencies on the receiving end of attacks that gave access to email and other sensitive resources. Federal agencies using the software were instructed on Sunday to disconnect systems that run the software and perform a forensic analysis of their networks. Premiere security firm FireEye says it was breached by nation-state hackers Security firm FireEye, which last week disclosed a serious breach of its own network, said that hackers backed by a nation state compromised a SolarWinds software update mechanism and then used it to infect selected customers who installed a backdoored version of the company’s Orion network management tool. The backdoor infected customers who installed an update from March to June of this year, SolarWinds said in a document filed on Monday with the Securities and Exchange Commission. SolarWinds, which said SolarWinds has about 300,000 Orion customers, put the number of affected customers at about 18,000.' -- source: https://arstechnica.com/information-technology/2020/12/18000-organizations-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Wormable code-execution flaw in Cisco Jabber has a severity rating of 9.9 out of 10
by Peter Reutemann 14 Dec '20

14 Dec '20

'Cisco has patched its Jabber conferencing and messaging application against a critical vulnerability that made it possible for attackers to execute malicious code that would spread from computer to computer with no user interaction required. Again. A single text is all it took to unleash code-execution worm in Cisco Jabber The vulnerability, which was first disclosed in September, was the result of several flaws discovered by researchers at security firm Watchcom Security. First, the app failed to properly filter potentially malicious elements contained in user-sent messages. The filter was based on an incomplete blocklist that could be bypassed using a programming attribute known as onanimationstart. Messages that contained the attribute passed directly to DOM of an embedded browser. Because the browser was based on the Chromium Embedded Framework, it would execute any scripts that made it through the filter. With the filter bypassed, the researchers still had to find a way to break out of a security sandbox that’s designed to keep user input from reaching sensitive parts of the operating system. The researchers eventually settled on a function called CallCppFunction, which among other things Cisco Jabber uses to open files one user receives from another. [...] The researchers recommended that the updates be installed as soon as possible. Until all employees are patched, organizations should consider disabling all external communications. The vulnerabilities affect all currently supported versions of the Cisco Jabber client (12.1 through 12.9).' -- source: https://arstechnica.com/information-technology/2020/12/wormable-zero-click-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hackers Are Selling More Than 85,000 MySQL Databases On a Dark Web Portal
by Peter Reutemann 14 Dec '20

14 Dec '20

'For the past year, hackers have been breaking into MySQL databases, downloading tables, deleting the originals, and leaving ransom notes behind, telling server owners to contact the attackers to get their data back. If database owners don't respond and ransom their data back in nine days, the databases are then put up on auction on a dark web portal. "More than 85,000 MySQL databases are currently on sale on a dark web portal for a price of only $550/database," reports ZDNet: This suggests that both the DB intrusions and the ransom/auction web pages are automated and that attackers don't analyze the hacked databases for data that could contain a higher concentration of personal or financial information. Signs of these ransom attacks have been piling up over the course of 2020, with the number of complaints from server owners finding the ransom note inside their databases popping up on Reddit, the MySQL forums, tech support forums, Medium posts, and private blogs.' -- source: https://developers.slashdot.org/story/20/12/12/1943216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Open Source Developers Say Securing Their Code Is 'Insufferably Boring' and 'Soul-Withering'
by Peter Reutemann 14 Dec '20

14 Dec '20

'"A new survey of the free and open-source software (FOSS) community conducted by the Linux Foundation suggests that contributors spend less than 3% of their time on security issues and have little desire to increase this," reports TechRepublic: Moreover, responses indicated that many respondents had little interest in increasing time and effort on security. One respondent commented that they "find the enterprise of security a soul-withering chore and a subject best left for the lawyers and process freaks," while another said: "I find security an insufferably boring procedural hindrance." The researchers concluded that a new approach to the security and auditing of FOSS would be needed to improve security practices, while limiting the burden on contributors. Some of the most requested tools from contributors were bug and security fixes, free security audits, and simplified ways to add security-related tools to their continuous integration (CI) pipelines. "There is a clear need to dedicate more effort to the security of FOSS, but the burden should not fall solely on contributors," read the report. "Developers generally do not want to become security auditors; they want to receive the results of audits..." The researchers continued: "One way to improve a rewrite's security is to switch from memory-unsafe languages (such as C or C++ ) into memory-safe languages (such as nearly all other languages)," researchers said. "This would eliminate entire classes of vulnerabilities such as buffer overflows and double-frees." Also interesting: money "scored very low in developers' motivations for contributing to open-source projects, as did a desire for recognition amongst peers," according to TechRepublic. "Instead, developers said they were purely interested in finding features, fixes and solutions to the open-source projects they were working on. Other top motivations included were enjoyment and a desire to contribute back to the FOSS projects that they used."' -- source: https://news.slashdot.org/story/20/12/12/205206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Here Comes the Google Chrome Change that Worries Ad-Blocker Creators
by Peter Reutemann 14 Dec '20

14 Dec '20

'CNET reports: With the next version of Chrome, Google is moving ahead with a plan to improve privacy and security by reining in some abilities of extensions used to customize the browser. The move had angered some developers who expected earlier it would cripple ad blockers. Manifest v3, the programming interface behind Google's security plans, will arrive with Chrome 88 in mid-January, Google said Wednesday at the Chrome Dev Summit. Extensions using the earlier Manifest v2 will still work for at least a year... Among other things, Manifest v3 limits the number of "rules" that extensions may apply to a web page as it loads. Rules are used, for example, to check if a website element comes from an advertiser's server and should therefore be blocked. Google announced the changes two years ago. Reducing the number of rules allowed angered creators of extensions like the uBlock Origin ad blocker and the Ghostery tracking blocker. They said the rules limits will stop their extensions from running their full lists of actions to screen ads or block tracking. That could let websites bypass extensions — and the preferences of people who installed them... The shift brought on by Manifest V3 will spread to all browsers, to the detriment of ad blocking software, predicted Andrey Meshkov, co-founder and chief technology officer of AdGuard, an ad-blocking extension... Ghostery is working to update its extension for Manifest V3 but would rather spend its time on "real privacy innovations," President Jeremy Tillman said in a statement Wednesday. "We still have real misgivings that these changes have more to do with Google protecting its bottom line than it does with improving security for Chrome users...." The importance of the Chrome team's choices are magnified by the fact that other browsers, including Microsoft Edge, Vivaldi , Opera and Brave, are built on its Chromium open-source foundation. Microsoft said it will embrace Manifest v3, too. "Another Manifest v3 change is that extensions no longer may update their abilities by downloading code from third-party sites. "The entire extension now must be distributed through the Chrome Web Store, a measure Google says improves security screens and speeds reviews."' -- source: https://tech.slashdot.org/story/20/12/13/0012217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Well here is a surprise for those that have long used CentOS as the community-supported rebuild of Red Hat Enterprise Linux...

From a report: For those relying on CentOS 8 to enjoy the reliability and features of Red Hat Enterprise Linux 8 but without the licensing costs, etc, that will end in 2021. At the end of 2021, CentOS 8 will no longer be maintained but CentOS 7 will stick around in a supported maintenance state until 2024. The CentOS Project will be focused moving forward just on CentOS Stream as the upstream/development branch of Red Hat Enterprise Linux. CentOS 8 users are encouraged to begin transitioning to CentOS Stream 8. The CentOS Project announced this shift in focus today via the CentOS Blog.

Random Firefox Tweaks
by Lawrence D'Oliveiro 12 Dec '20

12 Dec '20

Been looking at various settings changes you can make in the “about:config” page in Firefox. Here are a couple I have found useful: * keyword.enabled -- set to false to stop Firefox trying to do a search on the contents of the address box if it doesn’t match a URL. This is why I have a search box separate from the address box. * browser.fixup.alternate.enabled -- set to false to stop it helpfully tacking on “www.” and “.com” if the original URL you type doesn’t work. I have occasionally been confused by it complaining about not finding a URL, but showing a different one from the one I typed. By the way, when you first try to view this page, Firefox shows you a warning to ensure you understand the consequences of messing about with settings at this level. It remembers it has shown you this warning by adding the following line to the prefs.js file in your profile: user_pref("browser.aboutConfig.showWarning", false); Firefox seems to overwrite this file when it quits, and reloads it when it is launched again.

South Korea Finally Gets Rid Of ActiveX
by Lawrence D'Oliveiro 11 Dec '20

11 Dec '20

Being just about the first country in the world to introduce secure online banking (in 1999!) came at a cost to the Republic of Korea: because SSL/TLS wasn’t widespread at the time, they had to cobble together a solution based on Microsoft’s ActiveX technology. This made it specific to Windows. It worked OK for a while, but as computing platforms have continued to evolve, this dependency on a “legacy” technology has become increasingly annoying to just about everybody. Then in 2017, it actually became an election campaign promise to get rid of this. And finally, now, the promise is being fulfilled. <https://www.theregister.com/2020/12/10/south_korea_activex_certs_dead/>

Brave Browser-Maker Launches Privacy-Friendly News Reader
by Peter Reutemann 11 Dec '20

11 Dec '20

'Ars Technica: Brave Software, maker of the Brave Web browser, is introducing a news reader that's designed to protect user privacy by preventing parties -- both internal and third party -- from tracking the sites, articles, and story topics people view. Brave Today, as the service is called, is using technology that the company says sets it apart from news services offered by Google and Facebook. It's designed to deliver personalized news feeds in a way that leaves no trail for Brave, ISPs, and third parties to track. The new service is part of Brave's strategy of differentiating its browser as more privacy-friendly than its competitors'. Key to Brave Today is a new content delivery network the company is unveiling. Typically, news services use a single CDN to cache content and then serve it to users. This allows the CDN or the service using it to see both the IP address and news feed of each user, and over time, that data can help services build detailed profiles of a person's interests. The Brave Today CDN takes a different approach. It's designed in a way that separates a user's IP address from the content they request. One entity offers a load-balancing service that receives TLS-encrypted traffic from the user. The load balancer then passes the traffic on to the CDN that processes the request. The load balancer knows the user's IP address but, because the request is encrypted, has no visibility into the content the user is seeking. The CDN, meanwhile, sees only the request but has no way of knowing the IP address that's making it. Responses are delivered in reverse order. To prevent the data from being combined, Brave says that it will use one provider for load balancing and a different one for content delivery. To prevent the load-balancing provider from using the size of the requests and responses to infer the contents of the encrypted data, the service will also use a technique called padding, which adds characters to the plaintext before it's encrypted. The CDN uses several other techniques to preserve the anonymity of users. Among them: stripping out various headers that could be used to identify the person making the request. Furthermore, Brave is also taking steps to shield user information from its own employees. "... [T]he company has configured its account with the load-balancing provider to restrict access to its logging resources," reports Ars. "The load-balancing provider also doesn't provide the ability for customers to use the proxy protocol to inject the requester's IP address into outgoing requests. In case that changes, however, Brave has also entered into a contract with the load balancer that restricts access to logs or use of the protocol, even if Brave asks."' -- source: https://yro.slashdot.org/story/20/12/10/2151244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Exposes Adrozek, Malware That Hijacks Chrome, Edge, and Firefox
by Peter Reutemann 11 Dec '20

11 Dec '20

'Microsoft has raised the alarm today about a new malware strain that infects users' devices and then proceeds to modify browsers and their settings in order to inject ads into search results pages. From a report: Named Adrozek, the malware has been active since at least May 2020 and reached its absolute peak in August this year when it controlled more than 30,000 browsers each day. But in a report today, the Microsoft 365 Defender Research Team believes the number of infected users is much, much higher. Microsoft researchers said that between May and September 2020, they observed "hundreds of thousands" of Adrozek detections all over the globe. Based on internal telemetry, the highest concentration of victims appears to be located in Europe, followed by South and Southeast Asia. Microsoft says that, currently, the malware is distributed via classic drive-by download schemes. Users are typically redirected from legitimate sites to shady domains where they are tricked into installing malicious software. The boobytrapped software installs the Androzek malware, which then proceeds to obtain reboot persistence with the help of a registry key.' -- source: https://news.slashdot.org/story/20/12/10/1857222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Origins Of T he C Programming Language
by Lawrence D'Oliveiro 10 Dec '20

10 Dec '20

This article <https://arstechnica.com/features/2020/12/a-damn-stupid-thing-to-do-the-orig…> goes a bit more in-depth into the precursors of the C programming language. The story begins with a computer scientist from a well-connected family named Christopher Strachey (I remember the name of his uncle Lytton as the author of a volume of short biographies in my parents’ library called “Eminent Victorians”), who led a group to create a language called “CPL”. CPL proved a bit too ambitious to implement at the time. And it didn’t help that its designers insisted on certain syntactical niceties that might be considered more literary than practical. (Reflecting a certain British public-school background, I suppose ...) But a cut-down subset of this was implemented, with the aim of using it as a “bootstrap” language for writing the compiler for the full language. This was BCPL, and it turned out to be useful for a range of programming projects. The group at AT&T Bell Labs got hold of this after the Labs pulled out of the MULTICS project, and implemented an even more cut-down version called “B”, which could run on the limited memory of the PDP-7 which was all they had at the time. Then a later enhancement of this was called “New B” or “NB”. Several attempts were made to rewrite the fledgling Unix operating system in NB, which didn’t work. After each attempt, the language was revised to add more features. Finally, after the addition of structured types, the result was a language sufficiently useful to write an OS, and sufficiently different to warrant a new name. So it was dubbed “C”.

Bye-Bye DB2, Bye-Bye Oracle, Hello Postgres
by Lawrence D'Oliveiro 09 Dec '20

09 Dec '20

A report on how a couple of companies -- German IT outfit BG Phoenics and Indian one TransUnion CIBIL -- migrated their entire mass of internal company database deployments off proprietary DBMSes -- IBM DB2 in one case, Oracle in the other -- to Postgres EDB: <https://www.theregister.com/2020/12/08/leaving_ibm_db2_for_postgres/>. In both cases, a big factor was the licensing conditions, which made it very complicated to do any changes to database usage. The improvement in agility was major: Since going live, the user found the deployment of new instances in Postgres much faster than it had been in Db2, down from around 20 hours spread over two weeks to 40 to 60 minutes. Of course an Oracle advocate has to say “[Postgres] is not as scalable as a proprietary database like Oracle or SQL Server”. But I would suggest they think twice about such a pronouncement. Remember that Facebook runs its entire multi-billion-user operation on MySQL, and I’m sure Postgres can scale to that level as well. Where is there an Oracle or DB2 deployment of that size and throughput requirement? I don’t think such a thing exists.

Amazon, Amex To Fund Software Developers in New GitHub Program
by Peter Reutemann 09 Dec '20

09 Dec '20

'Amazon.com, American Express, Daimler AG and Stripe are among those joining a new GitHub program that will let companies directly fund open-source projects and software developers that are key to their businesses. From a report: It's an expansion of GitHub's Sponsors program, which previously let individuals support software projects and the millions of developers who use the digital platform to collaborate on, share and store code. GitHub, whose parent company Microsoft will also participate in the new service announced Tuesday, expects the change to dramatically increase the number of contributions. The year-old sponsors service has already generated enough money for some developers to rely on it as full-time work, said Devon Zuegel, GitHub's director of product for the communities department.' -- source: https://developers.slashdot.org/story/20/12/08/1821203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GE Puts Default Password In Radiology Devices, Leaving Healthcare Networks Exposed
by Peter Reutemann 09 Dec '20

09 Dec '20

'Ars Technica: Dozens of radiology products from GE Healthcare contain a critical vulnerability that threatens the networks of hospitals and other health providers that use the devices, officials from the US government and a private security firm said on Tuesday. The devices -- used for CT scans, MRIs, X-Rays, mammograms, ultrasounds, and positron emission tomography -- use a default password to receive regular maintenance. The passwords are available to anyone who knows where on the Internet to look. A lack of proper access restrictions allows the devices to connect to malicious servers rather than only those designated by GE Healthcare. Attackers can exploit these shortcomings by abusing the maintenance protocols to access the devices. From there, the attackers can execute malicious code or view or modify patient data stored on the device or the hospital or healthcare provider servers. Aggravating matters, customers can't fix the vulnerability themselves. Instead, they must request that the GE Healthcare support team change the credentials. Customers who don't make such a request will continue to rely on the default password. Eventually, the device manufacturer will provide patches and additional information. The flaw has a CVSS severity rating of 9.8 out of 10 because of the impact of the vulnerability combined with the ease of exploiting it. Security firm CyberMDX discovered the vulnerability and privately reported it to the manufacturer in May. The US Cyber Security and Infrastructure Security Agency is advising affected healthcare providers to take mitigation steps as soon as possible. In a statement, GE Healthcare officials wrote: "We are not aware of any unauthorized access to data or incident where this potential vulnerability has been exploited in a clinical situation. We have conducted a full risk assessment and concluded that there is no patient safety concern. Maintaining the safety, quality, and security of our devices is our highest priority. We are providing on-site assistance to ensure credentials are changed properly and confirm proper configuration of the product firewall. Additionally, we are advising the facilities where these devices are located to follow network management and security best practices."

FireEye, a Top Cybersecurity Firm, Says It Was Hacked By a Nation-State
by Peter Reutemann 09 Dec '20

09 Dec '20

'The New York Times : For years, the cybersecurity firm FireEye has been the first call for government agencies and companies around the world who have been hacked by the most sophisticated attackers, or fear they might be. Now it looks like the hackers -- in this case, evidence points to Russia's intelligence agencies -- may be exacting their revenge. FireEye revealed on Tuesday that its own systems were pierced by what it called "a nation with top-tier offensive capabilities." The company said hackers used "novel techniques" to make off with its own tool kit, which could be useful in mounting new attacks around the world. It was a stunning theft, akin to bank robbers who, having cleaned out local vaults, then turned around and stole the F.B.I.'s investigative tools. In fact, FireEye said on Tuesday, moments after the stock market closed, that it had called in the F.B.I. The $3.5 billion company, which partly makes a living by identifying the culprits in some of the world's boldest breaches -- its clients have included Sony and Equifax -- declined to say explicitly who was responsible. But its description, and the fact that the F.B.I. has turned the case over to its Russia specialists, left little doubt who the lead suspects were and that they were after what the company calls "Red Team tools." These are essentially digital tools that replicate the most sophisticated hacking tools in the world. FireEye uses the tools — with the permission of a client company or government agency -- to look for vulnerabilities in their systems. Most of the tools are based in a digital vault that FireEye closely guards. The hack raises the possibility that Russian intelligence agencies saw an advantage in mounting the attack while American attention -- including FireEye's -- was focused on securing the presidential election system. At a moment that the nation's public and private intelligence systems were seeking out breaches of voter registration systems or voting machines, it may have a been a good time for those Russian agencies, which were involved in the 2016 election breaches, to turn their sights on other targets. The hack was the biggest known theft of cybersecurity tools since those of the National Security Agency were purloined in 2016 by a still-unidentified group that calls itself theShadowBrokers. [...] The N.S.A.'s tools were most likely more useful than FireEye's since the U.S. government builds purpose-made digital weapons. FireEye's Red Team tools are essentially built from malware that the company has seen used in a wide range of attacks. Still, the advantage of using stolen weapons is that nation-states can hide their own tracks when they launch attacks.' -- source: https://it.slashdot.org/story/20/12/08/2247219 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Next Step In DNS Privacy
by Lawrence D'Oliveiro 09 Dec '20

09 Dec '20

We already have mechanisms called “DNS-over-HTTPS” (DoH) and “DNS-over-TLS” (DoT) to encrypt your DNS queries so intermediaries cannot eavesdrop on them. However, the DNS server you are querying still knows what you are asking for, and can tie that to the IP address that you are querying from. So the next step is called “Oblivious DNS” (“over HTTPS”?) or “ODoH” <https://arstechnica.com/information-technology/2020/12/cloudflare-apple-and…>. This one interposes a proxy to relay the encrypted query and response between the client machine and DNS server. The proxy cannot decrypt the communications, and its presence hides the client’s IP address from the server, further increasing your privacy. To recap: the DNS server knows what you are asking for, but not who is asking. The proxy knows who is asking, but not what they are asking for. Given the controversy from some parties over the existing mechanisms (remember when the British Internet Service Providers’ Association dubbed Mozilla a “villain” for implementing DoH <https://www.theregister.com/2019/07/10/ispa_clears_mozilla/>?), I wonder what kind of hoo-hah this further development will trigger...

Will Businesses Make 2021 The Year of the Linux Desktop?
by Peter Reutemann 08 Dec '20

08 Dec '20

'Writing for TechRepublic, open source advocate Jack Wallen predicts 2021 will be a year where open source technology dominates the world of big data even more than 2021 (with a big role predicted for SUSE). But he also sees businesses cutting costs by switching to open source solutions — including a big move to Linux on enterprise desktops, thanks to enterprise-ready options now available from System76, Lenovo, and Dell: This will have the added benefit of even more companies jumping into the mix and offering more and more desktops and laptops, all powered by Linux and open source technology. One added bonus for this movement is that System76 will finally gain the recognition they've deserved for so many years. Linux on the desktop would not be where it is today, had it not been for their stalwart support for open source technology. Year after year, System76 has proved that high-quality, business-class systems, powered by Linux, can be produced at a level befitting the enterprise. That success within the realm of business will start trickling down to consumers. As more and more people start using Linux at their place of business, they'll begin seeing the benefits of the open source operating system and desire to adopt it for their home computers. I suspect that by the end of 2021, we'll see Linux desktop market share to finally break the 10% bubble. It may not sound like much, but given how Linux has hovered around 2% and maxed out at 5%, that 10% figure is like a dream come true. That's only the tip of the iceberg. Although Linux will max out at around 10% by the end of the year, it will lead to continued growth over the coming years.' -- source: https://linux.slashdot.org/story/20/12/07/0332259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Should Qualcomm Feel Threatened By Apple's M1 Macs?
by Peter Reutemann 07 Dec '20

07 Dec '20

'PCMag.com's lead mobile analyst calls Qualcomm "a little too unbothered by Apple's M1 Macs" Qualcomm executives brushed off a question about Apple's new M1-based Macs during a question-and-answer session at the company's Snapdragon Summit today, where Qualcomm announced a new flagship smartphone chipset but no upgrades to its year-old chips for PCs... In general, reviews of Qualcomm-powered laptops such as the Microsoft Surface Pro X have celebrated the devices' long battery life, but lamented problems with third-party apps that were originally coded for Intel processors. That stands in stark contrast to Apple's new M1-based Macs, which don't seem to be slowed down as badly by older software... "It's a great validation of what we've been doing for the past few years and [Qualcomm's product line] is just going to get stronger and stronger as we broaden our scope," said Alex Katouzian, Qualcomm SVP for mobile. Katouzian made sure to subtly call out ways in which Qualcomm's always-connected PCs are superior to Apple's newest Macs. The Macs lack 4G connectivity and still have poor-quality, 720p front-facing cameras... Katouzian also pointed out that (presumably unlike Apple) Qualcomm addresses "many tiers...and many price points" with its 7c, 8c, and 8cx laptop chipsets, letting Windows laptop makers drive prices well below the MacBook Air's $999 list price. The core problem with Qualcomm's always-connected PC strategy is one that Qualcomm itself can't fix. While Qualcomm could, and probably will, soon announce a laptop chip that's based on the new Snapdragon 888 and has a level of raw power closer to Apple's M1, it's really down to Microsoft, as well as peripheral and app makers to solve the platform incompatibilities that have frustrated PC reviewers. Hot Hardware cites Microsoft's promises of changes come in future updates to Windows 10, arguing that "with the arrival of x64 emulation and a growing library of native Arm64 apps, Windows 10 on Arm is going to be an even more powerful platform." >From a performance perspective, while running Windows 10 on Arm, these [Snapdragon 8cx] chips may currently be at a disadvantage to the Apple M1, but some day in the not so distant future that might not be the case. We have no doubt that Qualcomm is likely working on a new Windows PC-centric SoC that is based on Snapdragon 888 or similar architecture. Qualcomm has promised a 25 percent uplift in CPU and a 35% lift in GPU performance over the Snapdragon 865, with the Snapdragon 888, which already offers a big boost over the previous gen Snapdragon 855/8cx. So, Qualcomm has the potential to put up a strong showing against the Apple M1, whenever its next-generation Snapdragon PC chip launches. That may be, but John Gruber at Daring Fireball argues that currently "M1 Macs embarrass all other PCs — all Intel-based Macs, including automobile-priced Mac Pros, and every single machine running Windows or Linux." Those machines are just standing around in their underwear now because the M1 stole all their pants. Well, that just doesn't happen, your instincts tell you. One company, even a company like Apple, doesn't just embarrass the entire rest of a highly-competitive longstanding industry. But just because something hasn't happened — or hasn't happened in a very long while — doesn't mean it can't happen. And in this case, it just happened... M1 Macs completely upend what we can and should expect from PCs. It's a breakthrough along the lines of the iPhone itself in 2007.' -- source: https://hardware.slashdot.org/story/20/12/06/060238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Richard Stallman Answers Questions at EmacsConf 2020
by Peter Reutemann 07 Dec '20

07 Dec '20

'All the videos have now appeared online for the talks at this year's virtual EmacsConf 2020, "the conference about the joy of Emacs, Emacs Lisp, and memorizing key sequences." And among them are an appearance by 67-year-old Richard Stallman, reminding the audience he'd created the first Emacs editor in 1976 "with some help from Guy Steele," then created GNU Emacs in 1984. Stallman was there to tell the history of the GNU Emacs Lisp Package Archive (and the licensing issues involved) — and how it's ultimately led to the creation of the NonGNU ELPA. "The fundamental plan of NonGNU ELPA is that we won't ask for copyright assignments for those packages, so we won't be able to put them into core Emacs, at least not easily — but we will have some control over how we distribute them. We can put any package into NonGNU ELPA as long as its free software. "If we like it, we can set up that way for users to get it. We can put the package in exactly as it is, if there's no problem at all with it. We can make an arrangement with the package's developers to work on it with us and maintain it directly for distribution by NonGNU ELPA. But if they are not interested, we can put it in ourselves, and if we need to make any changes we can do so. So NonGNU ELPA is not meant to be just a way that others can distribute their packages. Its meant at least in a minimal, technical sense to work with GNU Emacs, and we will make changes if necessary so that it works smoothly with GNU Emacs... "The idea is to have a single Git repository where you can download various packages, but they won't be maintained there. Each of those packages will be copied automatically from some other place, probably some other people have the right access to work on it. This way we can avoid giving a gigantic number of people access to it. "So far NonGNU ELPA is just a plan. We need people to implement the plan, so if you'd like to help, please write to me. I think this is a very important step for progress, and it's got to be implemented. Thanks, and happy hacking." Stallman provided a status update on NonGNU ELPA as part of the 46-minute Q&A that followed.

One of the Internet’s most aggressive threats could take UEFI malware mainstream
by Peter Reutemann 04 Dec '20

04 Dec '20

'One of the Internet’s most aggressive threats has just gotten meaner, with the ability to infect one of the most critical parts of any modern-day computer. Trickbot is a piece of malware that’s notable for its advanced capabilities. Its modular framework excels at gaining powerful administrator privileges, spreading rapidly from computer to computer in networks and performing reconnaissance that identifies infected computers belonging to high-value targets. It often uses readily available software like Mimikatz or exploits like EternalBlue stolen from the National Security Agency. Once a simple banking fraud trojan, Trickbot over the years has evolved into a full-featured malware-as-a-service platform. Trickbot operators sell access to their vast number of infected machines to other criminals, who use the botnet to spread bank trojans, ransomware, and a host of other malicious software. Rather than having to go through the hassle of ensnaring victims themselves, customers have a ready-made group of computers that will run their crimeware. Now, Trickbot has acquired a new power: the ability to modify a computer’s UEFI. Short for Unified Extensible Firmware Interface, UEFI is the software that bridges a computer’s device firmware with its operating system. As the first piece of software to run when virtually any modern machine is turned on, it’s the first link in the security chain. Because the UEFI resides in a flash chip on the motherboard, infections are difficult to detect and remove.' -- source: https://arstechnica.com/information-technology/2020/12/dangerous-uefi-malwa… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

FBI Warns of Email Forwarding Rules Being Abused in Recent Hacks
by Peter Reutemann 03 Dec '20

03 Dec '20

'The US Federal Bureau of Investigation says that cyber-criminals are increasingly relying on email forwarding rules in order to disguise their presence inside hacked email accounts. From a report: In a PIN (Private Industry Notification) alert sent last week and made public today, the FBI says the technique has been seen and abused in recent BEC (Business Email Compromise) attacks reported over the summer. The hackers' technique relies on a feature found in some email services called "auto-forwarding email rules." As its name implies, the feature allows the owner of an email address to set up "rules" that forward (redirect) an incoming email to another address if a certain criteria is met. Threat actors absolutely love email auto-forwarding rules as they allow them to receive copies of all incoming emails without having to log into an account each day -- and be at risk of triggering a security warning for a suspicious login.' -- source: https://it.slashdot.org/story/20/12/02/1944205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Malicious npm Packages Caught Installing Remote Access Trojans
by Peter Reutemann 03 Dec '20

03 Dec '20

'The security team behind the "npm" repository for JavaScript libraries removed two npm packages this Monday for containing malicious code that installed a remote access trojan (RAT) on the computers of developers working on JavaScript projects. From a report: The name of the two packages was jdb.js and db-json.js., and both were created by the same author and described themselves as tools to help developers work with JSON files typically generated by database applications. Both packages were uploaded on the npm package registry last week and were downloaded more than 100 times before their malicious behavior was detected by Sonatype, a company that scans package repositories on a regular basis. According to Sonatype's Ax Sharma, the two packages contained a malicious script that executed after web developers imported and installed any of the two malicious libraries. The post-install script performed basic reconnaissance of the infected host and then attempted to download and run a file named patch.exe that later installed njRAT, also known as Bladabindi, a very popular remote access trojan that has been used in espionage and data theft operations since 2015.' -- source: https://tech.slashdot.org/story/20/12/02/1939247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

iPhone Zero-Click Wi-Fi Exploit is One of the Most Breathtaking Hacks Ever
by Peter Reutemann 03 Dec '20

03 Dec '20

'Dan Goodin, writing for ArsTechnica: Earlier this year, Apple patched one of the most breathtaking iPhone vulnerabilities ever: a memory corruption bug in the iOS kernel that gave attackers remote access to the entire device -- over Wi-Fi, with no user interaction required at all. Oh, and exploits were wormable -- meaning radio-proximity exploits could spread from one nearby device to another, once again, with no user interaction needed. This Wi-Fi packet of death exploit was devised by Ian Beer, a researcher at Project Zero, Google's vulnerability research arm. In a 30,000-word post published on Tuesday afternoon, Beer described the vulnerability and the proof-of-concept exploit he spent six months developing single-handedly. Almost immediately, fellow security researchers took notice. "This is a fantastic piece of work," Chris Evans, a semi-retired security researcher and executive and the founder of Project Zero, said in an interview. "It really is pretty serious. The fact you don't have to really interact with your phone for this to be set off on you is really quite scary. This attack is just you're walking along, the phone is in your pocket, and over Wi-Fi someone just worms in with some dodgy Wi-Fi packets." Beer's attack worked by exploiting a buffer overflow bug in a driver for AWDL, an Apple-proprietary mesh networking protocol that makes things like Airdrop work. Because drivers reside in the kernel -- one of the most privileged parts of any operating system -- the AWDL flaw had the potential for serious hacks. And because AWDL parses Wi-Fi packets, exploits can be transmitted over the air, with no indication that anything is amiss.' -- source: https://apple.slashdot.org/story/20/12/02/1933245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Greg Kroah-Hartman: 'Don't Make Users Mad'
by Peter Reutemann 01 Dec '20

01 Dec '20

'Greg Kroah-Hartman, the Linux Foundation fellow currently responsible for stable Linux kernel releases, shared the lessons he's learned as a kernel developer that are applicable to other developers at this year's Linux App Summit. He started by showing how he could succinctly distill the essence of the talk into a single five-word slide: "Don't make your users mad...." Kroah-Hartman explains that one of Linus Torvalds' most deeply-held convictions: don't break userspace. "Other operating systems have this rule as well — it's a very solid rule — because we always want you to upgrade. And we want you to upgrade without worrying about it. We don't want you to feel scared. If you see a new release, and we say, 'Hey, this fixes a bunch of problems,' we don't want you to feel worried about taking that. That's really really important — especially with security...." If you do make a change, make sure there truly is a compelling reason. "You have to provide enough reason and enough goodness to force somebody to take the time to learn to do something else. That's very rare." His example of this was systemd, which unified a variety of service configurations and initialization processes. "They did it right. They provided all the functionality, they solved a real problem that was there. They unified all these existing tools and problems in such a way that it was just so much better to use, and it provided enough impetus that everybody was willing to do the work to modify their own stuff and move to the new model. It worked. People still complain about it, but it worked. Everybody switched... It works well. It solves a real problem. "That was an example of how you can provide a compelling reason to move on — and make the change."' -- source: https://linux.slashdot.org/story/20/11/28/0714229 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

From a report: Currently, Macs with the M1 chip do not support Windows and there is no Boot Camp feature as there is on Intel Macs, but support for Windows is a feature that many users would like to see. Using the open-source QEMU virtualizer, Graf was able to virtualize the Arm version of Windows on Apple's M1 chip, with no emulation. Since the M1 chip is a custom Arm SoC, it is no longer possible to install the x86 version of Windows or x86 Windows apps using Boot Camp, as was the case with previous Intel-based Macs. However, he said in a Tweet that when virtualized on an M1 Mac, "Windows ARM64 can run x86 applications really well. It's not as fast as Rosetta 2, but close."' -- source: https://apple.slashdot.org/story/20/11/27/2343223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft's 'Project Latte' Aims To Bring Android Apps To Windows 10
by Peter Reutemann 28 Nov '20

28 Nov '20

'Windows Central reports: Microsoft is working on a software solution that would allow app developers to bring their Android apps to Windows 10 with little to no code changes by packaging them as an MSIX and allowing developers to submit them to the Microsoft Store. According to sources familiar with the matter, the project is codenamed 'Latte' and I'm told it could show up as soon as next year. The company has toyed with the idea of bringing Android apps to Windows 10 before via a project codenamed Astoria that never saw the light of day. Project Latte aims to deliver a similar product, and is likely powered by the Windows Subsystem for Linux (WSL.) Microsoft will need to provide its own Android subsystem for Android apps to actually run, however. Microsoft has announced that WSL will soon get support for GUI Linux applications, as well as GPU acceleration which should aid the performance of apps running through WSL. It's unlikely that Project Latte will include support for Play Services, as Google doesn't allow Play Services to be installed on anything other than native Android devices and Chrome OS. This means that apps which require Play Services APIs will need to be updated to remove those dependencies before they can be submitted on Windows 10.' -- source: https://tech.slashdot.org/story/20/11/27/2027234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

2FA Bypass Discovered In Web Hosting Software cPanel
by Peter Reutemann 26 Nov '20

26 Nov '20

'ZDNet: Security researchers have discovered a major security flaw in cPanel, a popular software suite used by web hosting companies to manage websites for their customers. The bug, discovered by security researchers from Digital Defense, allows attackers to bypass two-factor authentication (2FA) for cPanel accounts. These accounts are used by website owners to access and manage their websites and underlying server settings. Access to these accounts is critical, as once compromised, they grant threat actors full control over a victim's site. On its website, cPanel boasts that its software is currently used by hundreds of web hosting companies to manage more than 70 million domains across the world. But in a press release today, Digital Defense says that the 2FA implementation on older cPanel & WebHost Manager (WHM) software was vulnerable to brute-force attacks that allowed threat actors to guess URL parameters and bypass 2FA -- if 2FA was enabled for an account. While brute-forcing attacks, in general, usually take hours or days to execute, in this particular case, the attack required only a few minutes, Digital Defense said today. Exploiting this bug also requires that attackers have valid credentials for a targeted account, but these can be obtained from phishing the website owner. The good news is that Digital Defense has privately reported the bug, tracked as SEC-575, to the cPanel team, which has already released patches last week.' -- source: https://it.slashdot.org/story/20/11/25/2227200 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

WireGuard for Windows 0.3.1 is the release you’ve been waiting for
by Peter Reutemann 26 Nov '20

26 Nov '20

'This Monday, WireGuard founder and lead developer Jason Donenfeld announced a new WireGuard release for the Windows platform. The release is something of a godsend for administrators hoping to implement WireGuard as a replacement for more traditional end-user VPNs in a business environment, adding several new features that will make their lives easier—or simply make its implementation possible, in environments where it otherwise would not. If you haven't heard about WireGuard yet, it's a relatively new VPN protocol featuring advanced cryptography. It's implemented from the ground up as an exercise in cleanly written, minimalist, maximally secure and performant code—and it succeeded at those goals well enough to get Linus Torvalds' own rarely-seen stamp of approval.

Linus Torvalds Would Like To Use An M1 Mac For Linux, But...
by Peter Reutemann 25 Nov '20

25 Nov '20

'Yes, Torvalds said he'd love to have one of the new M1-powered Apple laptops, but it won't run Linux and, in an exclusive interview he explains why getting Linux to run well on it isn't worth the trouble. Steven J. Vaughan-Nichols writes via ZDNet: Recently, on the Real World Technologies forum, Linux's creator Linus Torvalds was asked what he thought of the new M1-powered Apple laptops. Torvalds replied, "I'd absolutely love to have one if it just ran Linux." You may think, "what's the problem? Doesn't Linux run on practically every processor on the planet from 80386s to IBM s390x to the ARM family of which Apple's M1 chip is a child?" Well, yes, yes it does. But it takes more than a processor to run a computer. Torvalds would like to run Linux on these next-generation Macs. As he said, "I've been waiting for an ARM laptop that can run Linux for a long time. The new Air would be almost perfect, except for the OS. And I don't have the time to tinker with it, or the inclination to fight companies that don't want to help." Aye, there's the rub. In an exclusive interview, Torvalds expanded on why he can't see porting Linux to the M1-based Macs. "The main problem with the M1 for me is the GPU and other devices around it, because that's likely what would hold me off using it because it wouldn't have any Linux support unless Apple opens up." Still, while Torvalds knows Apple opening up their chipsets "seems unlikely, but hey, you can always hope." Even if that "wasn't an issue," Torvalds continued, "My personal hope would be more cores. Even in a laptop, I don't care about 20-hour battery life (and I wouldn't get it building kernels anyway). I'd rather plug it in a bit more often, and have 8 big cores." As for the Mac's limited RAM -- no more than 16GBs on current models -- he can live with that. "16GBs is actually ok by me because I don't tend to do things that require a lot more RAM. All I do is read email, do git and kernel compiles. And yes, I have 64GB in my desktop, but that's because I have 32 cores and 64 threads, and I do hugely parallel builds. Honestly, even then 32GB would be sufficient for my loads." That said, other developers and power users may want more from the new Macs, Torvalds thinks. "The people who really want tons of memory are the ones doing multiple VMs or huge RAW file photography and video."

Fwd: [NZLUG] CFP: LCA2021 Systems Administration Miniconf
by Peter Reutemann 25 Nov '20

25 Nov '20

Apologies for cross-posting, but since the event is down-under/online some people on this list might want to present/attend. Cheers, Peter ---------- Forwarded message --------- From: Ewen McNeill Date: Wed, Nov 25, 2020 at 11:33 AM Subject: [NZLUG] CFP: LCA2021 Systems Administration Miniconf To: NZ Linux Users Group <nzlug(a)lists.nzoss.org.nz> linux.conf.au 2021 is being held in an "Online Only" format from 23-25 January 2021 (Saturday through Monday!), starting with a Miniconf day on Saturday 2021-01-23. Based in UTC+11 (AEDT), it makes for a "sleep in" schedule for attending from New Zealand! Tickets are extra affordable this year (AU $125/$70/$30), and on sale now: https://lca2021.linux.org.au/attend/tickets/ (Sadly NZers don't get the electronic badge option :-( ) The Systems Administration Miniconf is one of four Miniconfs being held on Saturday 2021-01-23, and would welcome your presentation proposals now (closes 2020-12-18 AoE). For details see: https://sysadmin.miniconf.org/cfp21.html or read on, as the CFP is repeated below for your convenience. Ewen -=- cut here -=- LCA2021 Systems Administration Miniconf: Call for Presentations Saturday 2021-01-23 10:45-17:30 UTC+11 at Linux.conf.au 2021, Online Virtualisation has won! As of 2021, they have even virtualised our Systems Administration Miniconf! TL;DR: If you know our Miniconf, and know online presenting, you can propose your 15-20 minute Linux-related operations talk via the LCA2021 Dashboard *before* 2020-12-18: https://linux.conf.au/dashboard We'd particularly love your 2020 War Stories! Read on to find out more :-) Introduction ============ The linux.conf.au Systems Administration Miniconf returns for the 15th time as part of the very online linux.conf.au 2021, to be held without a venue (Venueless!), online on Saturday 2021-01-23, based in UTC+11 (AEDT -- Australian Eastern Daylight Time). The Systems Administration Miniconf focuses on tips, tricks, tools, and best practices used to manage real-world Linux environments both large and small. From single small servers through to 2,000 node Kubernetes Clusters. The organisers of the Systems Administration Miniconf would like to invite proposals for presentations to be delivered at the Miniconf. Please forward this CFP to your colleagues, peers, social networks, and other relevant mailing lists. Please help by encouraging submissions from people you would like to hear present at this Miniconf. We are open to presentations from speakers anywhere in the world, but please be mindful of the need to present during daytime in UTC+11 which may not be daytime in your local timezone (presenting late at night or very early in your morning is tricky!). More information and details of previous presentations at the Miniconf can be found at the website: https://sysadmin.miniconf.org/ Presentation Topics =================== 2020 has been a surprising year, and not the least for systems administration -- remote *everything* came with a rush, leaving many officeless, and dependent on the Internet and video conferencing. We would be particularly interested in talks about how 2020 has gone for your systems, how you dealt with the rapid changes in operating environment, and what your plans look like for a world where touching physical hardware frequently seems increasingly unlikely. Tell us your war stories :-) We would be very interested in retrospectives and "lessons learned" from the past year. We of course also welcome the usual range of talks on systems technology, automation, monitoring, troubleshooting, best current practices and so on. Presentations should be of a technical nature and speakers should assume that members of the audience have at least a couple of years experience in professional Linux administration (many in the audience will have decades of experience). Format of Presentations ======================= Due to the online only format, and its increased demands on the AV team, we have to fit into a more fixed structure within the LCA2021 Miniconf day. So we have less flexibility in our choice of presentations, that usual. We have openings for 15 and 20 minute short presentations (ie, each approximately half of a 45-minute "session", with a 10 minute gap in between). LCA2021 have indicated they have a strong preference for presentations to be given live, which will be easier if your local time zone is close to UTC+11 and you have an Internet connection with good upload speeds. For accepted Miniconf speakers the LCA2021 AV Team will want to check in with you *early* January 2021 to help ensure your presentation audio and visuals come across as well as possible. You may wish to watch the AV Team advice from PyConline AU 2020 to get some advanced hints on small changes you could make to help your presentation look and sound great: https://www.youtube.com/watch?v=C1TBqdULp4E Submitting talks ================ Please note that in order to give a presentation or attend the Miniconf you must be registered (and paid up by the time the conference happens) for the main linux.conf.au conference. Either for the full conference (Sat/Sun/Mon), or at least for the Miniconf day (Saturday 2021-01-23). As a one off "online only, LCA2021 only" special we have access to a small pool of "Miniconf Speaker" tickets, so if your employer will not pay for your ticket and the conference cost makes it difficult for you to attend/present please get in touch and we will see if we can help. To submit a talk to the LCA2021 Sysadmin Miniconf, create an account on the LCA2021 website: https://linux.conf.au/dashboard create a speaker profile, and then select "Systems Administration Miniconf Talk" (in the "New Proposal" section of the Dashboard), or while logged into the LCA2021 site, go directly to: https://linux.conf.au/proposals/submit/sysadmin-miniconf/ Questions should be sent to: lca2021 at sysadmin.miniconf.org Dates and Deadlines =================== To encourage early submissions, priority (both of inclusion and scheduling) will be given to presentations submitted by 23:59 (AoE -- ie any time zone) on Sunday 6 December 2020. If you have a good presentation idea, please let us know early, even if you need time to finalise the presentation abstract. 2020-12-06 - Deadline for early submissions 2020-12-11 - early acceptances 2020-12-18 - Deadline for all submissions 2020-12-21 - final acceptances 2020-12-24 - LCA2021 Sysadmin Miniconf initial programme published 2021-01-21 - LCA2021 Sysadmin Miniconf held (Online, UTC+11) Contact and Questions ===================== Please see our website at https://sysadmin.miniconf.org for more information on the miniconf, past presentations and presenting at it.

LISP presentation uploaded to WLUG github.
by Ian Stewart 25 Nov '20

25 Nov '20

Hi Folks, For last night's LISP presentation, the slide show file and the LISP demonstration programs have been uploaded to: https://github.com/WLUG/meetings/tree/master/2020/2020-11-23 The slide show is available in both .odp and .pdf formats. The demonstration programs all have shebangs for CLISP, but these may be changed to be for SBCL. The programs have been tested to work under both CLISP and SBCL. Note that SBCL seems to be fussier than CLISP and, for example, requires (defvar) functions before the variable could be loaded via a (setf) function. At the meeting Jake demonstrated the apropos function to help with finding symbols. An appendix slide has been added to the presentation to show this function. I have also added my first attempt at something resembling a real a LISP program, package-symbols.lisp. This program will list packages that are available to either SBCL or CLISP. Upon selecting a package, it will display all the symbols the package has. If the command line argument "function" is used (E.g., $ sbcl --script package-symbols function) then the symbols displayed will be filtered to only displaying symbols that are functions. cheers, Ian.

Gimp Turns 25
by Peter Reutemann 24 Nov '20

24 Nov '20

'The General Image Manipulation Program, GIMP, has turned 25. A brief celebration post detailed how the package started life as a July 1995 Usenet thought bubble by then-student Peter Mattis, who posted the following to several newsgroups: Suppose someone decided to write a graphical image manipulation program (akin to photoshop). Out of curiosity (and maybe something else), I have a few (2) questions: What kind of features should it have? (tools, selections, filters, etc.) What file formats should it support? (jpeg, gif, tiff, etc.)" Four months later, Mattis and fellow University of California Berkeley student Spencer Kimball delivered what they described as software "designed to provide an intuitive graphical interface to a variety of image editing operations." The software ran on Linux 1.2.13, Solaris 2.4, HPUX 9.05, and SGI IRIX. The answer to the file format support question turned out to be GIF, JPEG, PNG, TIFF, and XPM. The rest is history. Richard Stallman gave Mattis and Kimball permission to change the "General" in its name to "GNU", reflecting its open-source status. Today the program is released under the GNU General Public License. As the program added features such as layers, it grew more popular and eventually became a byword for offering a FOSS alternative to Photoshop even though the project pushes back against that description. The project's celebration page says volunteers did their "best to provide a sensible workflow to users by using common user interface patterns. That gave us a few questionable monikers like 'Photoshop for Linux', 'free Photoshop', and 'that ugly piece of software'. We still can wholeheartedly agree with the latter one only!"' -- source: https://it.slashdot.org/story/20/11/23/1946252 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mass-Produced, Librem 5 Linux Smartphone Begins Shipping to Customers
by Peter Reutemann 23 Nov '20

23 Nov '20

'This week Purism began shipping its mass-produced Librem 5 phone to customers, according to announcement from the company: The Librem 5 is a one-of-a-kind general-purpose computer in a phone form-factor that Purism has designed and built from scratch following a successful crowdfunding campaign that raised over $2.2 million. Both the hardware and software design is focused on respecting the end user's freedom and giving them control over their privacy and security. The Librem 5 doesn't run Android nor iOS but instead runs the same PureOS operating system as Purism's laptops and mini PC. The Librem 5 has unique hardware features including a user-removable cellular modem, WiFi card, and battery. Like with Librem laptops, the Librem 5 also features external hardware kill switches that cut power to the cellular modem, WiFi/Bluetooth, and front and back cameras and microphone so that the user can control when these devices are in use. All hardware switches can also be triggered together to enable "lockdown mode" which also disables the GPS, accelerometer and all other sensors... Another unique feature of the Librem 5 is convergence: the ability to connect the Librem 5 to a monitor or laptop dock and use it as a desktop computer running the same full-sized desktop applications as on Librem laptops. When in a phone form-factor, applications behave much like "responsive websites" and change their appearance for the smaller screen. This allows you to use the Librem 5 as a phone, a desktop, or a laptop with the same applications and same files. Their announcement notes their work on software making desktop applications "adaptive" to phone form factors, adding "This suite of software has now become the most popular software stack to use on other handheld Linux hardware." And they close with an appreciative comment from Purism's founder and CEO Todd Weaver: "Shipping the Librem 5 has been an immense multi-year developmental effort. It is the culmination of people's desire to see an alternative to Android and iOS and fund it, coupled with dedication from a team of experts addressing hardware, kernel, operating system, and applications that has turned a lofty near-impossible goal into reality. We have built a strong foundation and with the continued support of customers, the community, and developers, we will continue to deliver revolutionary products like the Librem 5 running PureOS."' -- source: https://mobile.slashdot.org/story/20/11/23/025228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Ubuntu Web Remix' Distro Offers Firefox-Based Chrome OS Alternative
by Peter Reutemann 23 Nov '20

23 Nov '20

'Rudra Saraswat is the creator of the Ubuntu Unity distro (which uses the Unity interface in place of Ubuntu's GNOME shell). But this week they released Ubuntu Web Remix, "a privacy-focused, open source alternative to Google Chrome OS/Chromium OS" using Firefox instead of Google Chrome/Chromium. Liliputing reports: If the name didn't give it away, this operating system is based on Ubuntu, but it's designed to offer a Chrome OS-like experience thanks to a simplified user interface and a set of pre-installed apps including the Firefox web browser, some web apps from /e/, and Anbox, a tool that allows you to run Android apps in Linux... You don't get the long battery life, cloud backup, and many other features that make Chromebooks different from other laptops (especially other cheap laptops). But if you're looking for a simple, web-centric operating system that isn't made by a corporate giant? Then I guess it's nice to have the option. Rudra Saraswat writes: An easy web-app (wapp) format has been created to package web-apps for the desktop. You can now create your own web apps using web technologies, package them for the desktop and install them easily. An experimental wapp store can be found at store.ubuntuweb.co, for distributing web apps. Developers and packagers can do pull requests at gitlab.com/ubuntu-web/ubuntu-web.gitlab.io to contribute wapps.

How Firefox Boosted Its JavaScript Performance
by Peter Reutemann 23 Nov '20

23 Nov '20

'InfoWorld reports: Firefox users can expect improved JavaScript performance in the Firefox 83 browser, with the Warp update to the SpiderMonkey JavaScript engine enabled by default. Also called WarpBuilder, Warp improves responsiveness and memory usage and speeds up page loads by making changes to JiT (just-in-time) compilers... Warp has been shown to be faster than Ion, SpiderMonkey's previous optimizing JiT, including a 20 percent improvement on Google Docs load time. Other JavaScript-intensive websites such as Netflix and Reddit also have shown improvement... Warp has replaced the front end — the MIR building phase — of the IonMonkey JiT... Mozilla also will continue to incrementally optimize the back end of the IonMonkey JiT, as Mozilla believes there is still room for improvement for JavaScript-intensive workloads.' -- source: https://news.slashdot.org/story/20/11/22/0412232 I agree, 83 feels snappier when browsing.

After Restoring YouTube-dl, GitHub Revamps Its Copyright Takedown Policy
by Peter Reutemann 22 Nov '20

22 Nov '20

'On October 23rd GitHub initially complied with a takedown request for the open-source project youtube-dl — and then after 24 days, reinstated it. "If there's a silver lining to the episode, it's that GitHub is implementing new policies to avoid a repeat of a repeat situation moving forward," reports Engadget: First, it says a team of both technical and legal experts will manually evaluate every single section 1201 claim. In instances where there's any ambiguity to a claim, the company says it will err on the side of developers and leave their repository online. If the company's technical and legal teams ultimately find any issues with a project, GitHub will give its owners the chance to address those problems before it takes down their work. Following a takedown, it will continue to give people the chance to recover their data — provided it doesn't include any offending code. GitHub is also establishing a $1 million defense fund to provide legal aid to developers against suspect section 1201 claims, as well as doubling down on its lobbying work to amend the DMCA and other similar copyright laws across the world.

Fearing Drama, Mozilla Opens Public Consultation Before Worldwide Firefox DoH Rollout
by Peter Reutemann 20 Nov '20

20 Nov '20

'Mozilla has opened today a public comment and consultation period about the ways it could enable support for the controversial privacy-centric DNS-over-HTTPS (DoH) protocol inside Firefox. From a report: The browser maker's decision to open a rare public consultation period comes after the organization faced criticism last year in the UK for its plans to support DoH inside Firefox. UK government officials, law enforcement agencies, and local internet service providers criticized Mozilla for developing and wanting to roll out DoH, a feature they said could have helped suspects bypass enterprise firewalls and parental controls blocklists -- even earning the browser maker a nomination for an "Internet Villain" award from a local ISP. All last year's hoopla was caused by DoH, a web protocol developed as an alternative to the classic DNS (Domain Name System). DoH works by encrypting DNS queries (which are normally sent out in clear text) and hiding them inside normal-looking HTTPS web traffic.' -- source: https://tech.slashdot.org/story/20/11/19/1711200 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

OpenStreetMap is Having a Moment
by Peter Reutemann 20 Nov '20

20 Nov '20

'Joe Morrison: The first time I spoke with Jennings Anderson, I couldn't believe what he was telling me. I mean that genuinely -- I did not believe him. He was a little incredulous about it himself. I felt like he was sharing an important secret with me that the world didn't yet know. The open secret Jennings filled me in on is that OpenStreetMap (OSM) is now at the center of an unholy alliance of the world's largest and wealthiest technology companies. The most valuable companies in the world are treating OSM as critical infrastructure for some of the most-used software ever written. The four companies in the inner circle -- Facebook, Apple, Amazon, and Microsoft -- have a combined market capitalization of over six trillion dollars. In almost every other setting, they are mortal enemies fighting expensive digital wars of attrition. Yet they now find themselves eagerly investing in and collaborating on OSM at an unprecedented scale (more on the scale later). What likely started as a conversation in a British pub between grad students in 2004 has spiraled out of control into an invaluable, strategic, voluntarily-maintained data asset the wealthiest companies in the world can't afford to replicate. I will admit that I used to think of OSM as little more than a virtuous hobby for over-educated Europeans living abroad -- a cutesy internet collectivist experiment somewhere on the spectrum between eBird and Linux. It's most commonly summarized with a variant of this analogy: OSM is to an atlas as Wikipedia is to an encyclopedia. OSM acolytes hate this comparison in the much same way baseball players resent when people describe the sport as "cricket for fat people." While vaguely truthful, it doesn't quite get to the spirit of the thing. OSM is incomparable. Over 1.5M individuals have contributed data to it. It averages 4.5M changes per day. The stats page on the OSM Wiki is a collection of hockey sticks.

Google is Rolling Out End-To-End Encryption for RCS in Android Messages Beta
by Peter Reutemann 20 Nov '20

20 Nov '20

'After two long, complicated years, every Android user worldwide (outside China) now has access to the next-gen texting standard that is replacing SMS. Google is directly offering RCS chat services through its Android Messages app to anybody who installs it and uses it as their default texting app, which partly bypasses a carrier rollout that, at times, has ranged from sluggish to incoherent to broken. From a report Just as importantly, Google has announced that it's finally beginning to enable a key privacy feature: end-to-end encryption. For Android users who use Android Messages, one-on-one chats will eventually be end-to-end encrypted by default, meaning neither carriers nor Google will be able to read the content of those messages. Even though encryption is only beginning to roll out to people who sign up for the public beta for Android Messages, turning on encryption for RCS is a very big deal. It's a massive privacy win, as it could mean that the de facto replacement for SMS will, by default, be private on the smartphone platform used by the vast majority of people worldwide. As for the people who use that other smartphone platform -- the iPhone -- we have no word on whether Apple intends to adopt the RCS standard. But as every carrier worldwide gets on board, and now that there is a clearer path to ensuring private communication with RCS, the pressure on Apple to participate is likely to build. Unfortunately, SMS becoming fully deprecated and replaced by RCS will only happen if all goes to plan for Google. Since initially announcing plans to transition to RCS as the primary texting platform for Android, the standard's rollout has been mired in confusion. In attempting to be neutral and make Android's texting a standard shared by carriers worldwide, Google set itself up with the job of herding multibillion-dollar cats -- with sadly predictable results.' -- source: https://tech.slashdot.org/story/20/11/19/1528230 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Apple Silicon Performance
by Lawrence D'Oliveiro 20 Nov '20

20 Nov '20

You may have seen reports popping up everywhere as Apple’s new Macs running its ARM-based “Apple Silicon” chips get into the hands of the first buyers. They seem to offer remarkable performance while still managing good battery life, even while a lot of the software they are running is still written for x86 processors and being translated on the fly through the “Rosetta 2” emulator layer. One of the secrets to that performance is that the system RAM is integrated into the CPU chipset <https://www.theregister.com/2020/11/19/apple_m1_high_bandwidth_memory_perfo…>. Yup, that means RAM is not upgradeable on these machines.

Microsoft’s “Project Reunion” Leads To More Fragmentation
by Lawrence D'Oliveiro 20 Nov '20

20 Nov '20

If you thought the Microsoft Windows development landscape was already confusing enough, consider this update <https://www.theregister.com/2020/11/19/microsoft_winui_windows/> on “Project Reunion” ... which [Windows Developer VP] Gallo described as “a common platform for new apps and APIs so that they will work down-level across supported versions of Windows.” A developer asked: “For a new desktop app what is your recommendation, UWP? WinUI, WPF or WinForm?” To which there was no simple answer. Indeed, while the presentation introduced WinUI version 3, it appears WinUI 2.x will also continue to be developed. Instead, Gallo talked about no longer having binary choices, but being able to mix and match in the brave new Reunion world. I wonder if anybody at Microsoft really understands what “Reunion” means ...

Google's Native Version of Chrome For Apple's ARM Macs Is Out Now
by Peter Reutemann 19 Nov '20

19 Nov '20

'According to Chrome product manager Mark Chang, Google's version of Chrome that support ARM Macs is now available to download. The Verge reports: In theory, a native version of the notoriously resource-hungry browser might run more efficiently on Apple's Arm-based computers. In our reviews of the MacBook Air, MacBook Pro, and Mac mini equipped with the new M1 chip, though, we found that the version of Chrome built for Intel chips already runs well on Apple's new Macs, so hopefully this native version runs even better. You'll be able to pick which version of Chrome to download from the browser's website. Google began rolling out a new version of Chrome on Tuesday, touting the "the largest gain in Chrome performance in years" thanks to some under-the-hood changes. The company's blog about the new release didn't mention anything about a version optimized for Apple's Arm-based Macs.' -- source: https://apple.slashdot.org/story/20/11/18/2239226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Massive, China-State-Funded Hack Hits Companies Around the World, Report Says
by Peter Reutemann 19 Nov '20

19 Nov '20

'Ars Technica: Researchers have uncovered a massive hacking campaign that's using sophisticated tools and techniques to compromise the networks of companies around the world. The hackers, most likely from a well-known group that's funded by the Chinese government, are outfitted with both off-the-shelf and custom-made tools. One such tool exploits Zerologon, the name given to a Windows server vulnerability, patched in August, that can give attackers instant administrator privileges on vulnerable systems. Symantec uses the code name Cicada for the group, which is widely believed to be funded by the Chinese government and also carries the monikers of APT10, Stone Panda, and Cloud Hopper from other research organizations. The group has been active in espionage-style hacking since at least 2009 and almost exclusively targets companies linked to Japan. While the companies targeted in the recent campaign are located in the United States and other countries, all of them have links to Japan or Japanese companies. The attacks make extensive use of DLL side-loading, a technique that occurs when attackers replace a legitimate Windows dynamic-link library file with a malicious one. Attackers use DLL side-loading to inject malware into legitimate processes so they can keep the hack from being detected by security software. The campaign also makes use of a tool that's capable of exploiting Zerologon. Exploits work by sending a string of zeros in a series of messages that use the Netlogon protocol, which Windows servers use to let users log into networks. People with no authentication can use Zerologon to access an organization's crown jewels -- the Active Directory domain controllers that act as an all-powerful gatekeeper for all machines connected to a network. Microsoft patched the critical privilege-escalation vulnerability in August, but since then attackers have been using it to compromise organizations that have yet to install the update. Both the FBI and Department of Homeland Security have urged that systems be patched immediately. Among the machines compromised during attacks discovered by Symantec were domain controllers and file servers. Company researchers also uncovered evidence of files being exfiltrated from some of the compromised machines.' -- source: https://it.slashdot.org/story/20/11/19/0124204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

$6 Billion Linux Deal? SUSE IPO Rumored
by Peter Reutemann 18 Nov '20

18 Nov '20

'ZDNet: According to Bloomberg, EQT is planning an IPO for German Linux and enterprise software company SUSE. EQT is a Swedish-based private equity firm with 50 billion euros in raised capital. SUSE is the leading European Union (EU) Linux distributor. Over the years, SUSE has changed owners several times. First, it was acquired by Novell in 2004. Then, Attachmate, with some Microsoft funding, bought Novell and SUSE in 2010. This was followed in 2014 when Micro Focus purchased Attachmate and SUSE was spun off as an independent division. Then, EQT purchased SUSE from Micro Focus for $2.5 billion in March 2019. With an IPO of approximately $6 billion, EQT would do very well for itself in very little time. Bloomberg states that the IPO talks are in a very preliminary stage. Nothing may yet come of these conversations. As for SUSE, a company representative said, "As a company, we are constantly exploring ways to grow. But as a matter of corporate policy, we do not comment on rumor or speculation in the market."' -- source: https://linux.slashdot.org/story/20/11/17/2148202 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox 83 Arrives With HTTPS-Only Mode and Faster Performance
by Peter Reutemann 18 Nov '20

18 Nov '20

'Mozilla today launched Firefox 83 for Windows, Mac, and Linux. An anonymous reader shares a report: Firefox 83's highlight feature is HTTPS-Only Mode, in which the browser attempts to establish fully secure connections to every website (just like the EFF's HTTPS Everywhere). If it can't, Firefox asks for your permission before connecting to a website that doesn't support secure connections. To enable HTTPS-Only Mode, click on Firefox's menu button, hit Preferences, then Privacy & Security, scroll down to HTTPS-Only Mode, and choose "Enable HTTPS-Only Mode in all windows."

GitHub Reinstates YouTube-dl Library After EFF Intervention
by Peter Reutemann 17 Nov '20

17 Nov '20

'GitHub has reinstated today the youtube-dl open-source project, a Python library that lets users download the source audio and video files behind YouTube videos. From a report: GitHub, a code-hosting repository, had previously removed the library from its portal after it received a controversial DMCA takedown request from the Recording Industry Association of America (RIAA) on October 23. In a DMCA takedown letter, RIAA argued that the library was being used to "circumvent the technological protection measures used by authorized streaming services such as YouTube" and to allow users to "reproduce and distribute music videos and sound recordings [...] without authorization." RIAA also noted that the project's source code "expressly suggests its use to copy and/or distribute the following copyrighted works." More specifically, RIAA used Section 1201 of the Digital Millennium Copyright Act (DMCA) to claim that the youtube-dl library was breaking copyright by providing a tool to circumvent copyrighted material -- even if the youtube-dl library didn't contain copyright-infringing code itself. But in a blog post today, GitHub said the library did not actually break Section 1201 of the DMCA, citing a letter it received from Electronic Frontier Foundation lawyers, who to take up the youtube-dl project's case. In the letter, the EFF team explained that Google does not have any technical measures in place to prevent the download of its videos -- all of which need to be made freely available to all kinds of apps, browsers, smart TVs, and more. Hence, EFF lawyers argued that the library could never be taken down under Section 1201 of the DMCA since the library doesn't actually circumvent any sort of copyright protection system in the first place.' -- source: https://yro.slashdot.org/story/20/11/16/1730250 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Ok Google: Please Publish Your DKIM Secret Keys
by Peter Reutemann 17 Nov '20

'Matthew Green, a cryptographer and professor at Johns Hopkins University, writes: The Internet is a dangerous place in the best of times. Sometimes Internet engineers find ways to mitigate the worst of these threats, and sometimes they fail. Every now and then, however, a major Internet company finds a solution that actually makes the situation worse for just about everyone. Today I want to talk about one of those cases, and how a big company like Google might be able to lead the way in fixing it. This post is about the situation with Domain Keys Identified Mail (DKIM), a harmless little spam protocol that has somehow become a monster. My request is simple and can be summarized as follows: Dear Google: would you mind rotating and publishing your DKIM secret keys on a periodic basis? This would make the entire Internet quite a bit more secure, by removing a strong incentive for criminals to steal and leak emails. The fix would cost you basically nothing, and would remove a powerful tool from hands of thieves.' -- source: https://tech.slashdot.org/story/20/11/16/1932234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

There’s Open Source, And There’s Open Source
by Lawrence D'Oliveiro 13 Nov '20

13 Nov '20

Vendors open-sourcing a bunch of code isn’t enough, if that code remains under the de-facto control of the vendor. It needs to be possible for a community to influence its development direction, rather than passively waiting for the next code drop from the vendor, according to Dave Airlie <https://www.theregister.com/2020/11/12/intel_igc_mesa/>. He says: “A warning then to anyone wishing for more vendor code sharing between OSes it generally doesn't end with Linux being better off, it ends up with Linux being more fragmented, harder to support and in the long run unsustainable.”

Ubuntu fixes bugs that standard users could use to become root
by Peter Reutemann 12 Nov '20

12 Nov '20

'Ubuntu developers have fixed a series of vulnerabilities that made it easy for standard users to gain coveted root privileges. “This blog post is about an astonishingly straightforward way to escalate privileges on Ubuntu,” Kevin Backhouse, a researcher at GitHub, wrote in a post published on Tuesday. “With a few simple commands in the terminal, and a few mouse clicks, a standard user can create an administrator account for themselves.” The first series of commands triggered a denial-of-service bug in a daemon called accountsservice, which as its name suggests is used to manage user accounts on the computer. To do this, Backhouse created a Symlink that linked a file named .pam_environment to /dev/zero, changed the regional language setting, and sent accountsservice a SIGSTOP. With the help of a few extra commands, Backhouse was able to set a timer that gave him just enough time to log out of the account before accountsservice crashed. When done correctly, Ubuntu would restart and open a window that allowed the user to create a new account that—you guessed it—had root privileges.' -- source: https://arstechnica.com/information-technology/2020/11/ubuntu-fixes-bugs-th… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

No, the New MacBook Air is Not Faster Than 98% of PC Laptops
by Peter Reutemann 12 Nov '20

12 Nov '20

'Gordon Mah Ung, writing at PC World: Let me just say it outloud, OK? Apple is full of it. I'm referring to Apple's claim that its fanless, Arm-based MacBook Air is "faster than 98 percent of PC laptops." Yes, you read that correctly: Apple officials literally claimed that the new MacBook Air using Apple's custom M1 chip is faster than 98 percent of all PC laptops sold this year. Typically, when a company makes such a claim, it publishes a benchmark, a performance test or actual details on what it's basing that marketing claim on. This to prevent lawyers from launching out of missile silos across the world. Apple's website restates the claim by stating: "M1 is faster than the chips in 98 percent of PC laptops sold in the past year." The site also includes a detail note that states: "Testing conducted by Apple in October 2020 using preproduction 13-inch MacBook Pro systems with Apple M1 chip and 16GB of RAM. Performance measured using select industry-standard benchmarks. PC configurations from publicly available sales data over the last 12 months. Performance tests are conducted using specific computer systems and reflect approximate performance of MacBook Pro." So, not only does Apple not say what tests it's basing its claims on, it doesn't even say where it sources the comparable laptops. Does that mean the new fanless MacBook Air is faster than, say, Asus' stupidly fast Ryzen 4000 based, GeForce RTX 2060-based Zephyrus G14? Does it mean the MacBook Air is faster than Alienware's updated Area 51M? The answer, I'm going to guess is "no." Not at all. Is it faster than the miniLED-based MSI Creator 17? Probably not, either. And what is that "performance" claim hinged on? CPU performance? GPU performance? Performance running Windows? Is it using the same application running on both platforms? Is it experiential? Is this running Red Dead Redemption II or Call of Duty: Black Ops Cold War? Is it running CyberLink's PowerDirector? Is it running Fortnite? While I have absolutely no idea what Apple is basing its claims on, I can tell you that I am 98 percent sure that any of the above laptops listed will wreck the MacBook Air doing any of the tasks I just named. When Apple makes its claims, my guess is they are comparing the new M1 to Intel-based processors ranging from Atom to Celeron N to Core i3 and up, all with integrated graphics. But by not defining the word "performance," all this becomes just pure marketing spin. And is it really fair to compare a $999 MacBook to one that costs $150? Because $150 PCs are included in the 98 percent of laptops sold. Maybe Apple should compare its own $150 MacBook Air against a $150 Chromebook or Windows-based laptop. Of course, that would mean Apple would have to sell a product that most people can afford. I have no doubt the M1 will be impressive, but do I think it's going to compare to 8-cores of Ryzen 4000 performance or a GeForce RTX 2060? No.' -- source: https://apple.slashdot.org/story/20/11/11/2114225 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Chrome To Block Tab-Nabbing Attacks
by Peter Reutemann 12 Nov '20

12 Nov '20

'Google will deploy a new security feature in Chrome next year to prevent tab-nabbing, a type of web attack that allows newly opened tabs to hijack the original tab from where they were opened. From a report: The new feature is scheduled to go live with Chrome 88, to be released in January 2021. While the term "tab-nabbing" refers to a broad class of tab hijacking attacks [see OWASP, Wikipedia], Google is addressing a particular scenario. This scenario refers to situations when users click on a link, and the link opens in a new tab (via the "target=_blank" attribute). These new tabs have access to the original page that opened the new link. Via the JavaScript "window.opener" function, the newly opened tabs can modify the original page and redirect users to malicious sites. This type of attack has powered quite a few phishing campaigns across the years. To mitigate this threat, browser makers like Apple, Google, and Mozilla have created the rel="noopener" attribute.' -- source: https://tech.slashdot.org/story/20/11/11/1558242 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Raspberry Pi 4 Can Be Safely Overclocked To 2.15 GHz
by Peter Reutemann 12 Nov '20

12 Nov '20

'When the Raspberry Pi 400 (a keyboard form-factor single board computer) was released last week, the company hinted at overclocking. Testing has now shown that the heat spreader used in that design does an excellent job. The chip was already clocked at 1.8 GHz, versus the stock 1.5 GHz in the original Raspberry Pi 4 Model B board. But it can be safely overclocked to 2.15 GHz, as can the Compute Module 4 with an adequate heat sink. At 2.0 GHz, the Pi 400 got up above 60 C and showed signs of continuing to warm up even after 50 minutes, but it was nowhere near throttling. So I tried 2.2 GHz, at which speed the CPU refused to boot entirely. Backing down to 2.15 GHz, it ran just fine, so I left it for three hours. It settled in at a cozy 62.5 C, which is warm, but well within specs. I ran the CM4 with the larger heatsink at 1.8 GHz to give some basis for comparison to the cheap heatsinks. What a big difference a big hunk of aluminum makes! It settled in at a comfortable 68 C or so. Even pushing it up to 2.15 GHz and leaving it for a couple hours, it stayed just a hair below 70C (158F) -- a safe margin on the throttling threshold -- and only a few degrees warmer than that huge heat spreader in the Pi 400.' -- source: https://hardware.slashdot.org/story/20/11/11/182203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Computer Scientists Achieve 'Crown Jewel' of Cryptography
by Peter Reutemann 11 Nov '20

11 Nov '20

'A cryptographic master tool called indistinguishability obfuscation has for years seemed too good to be true. Three researchers have figured out that it can work. Erica Klarreich, reporting for Quanta Magazine: In 2018, Aayush Jain, a graduate student at the University of California, Los Angeles, traveled to Japan to give a talk about a powerful cryptographic tool he and his colleagues were developing. As he detailed the team's approach to indistinguishability obfuscation (iO for short), one audience member raised his hand in bewilderment. "But I thought iO doesn't exist?" he said. At the time, such skepticism was widespread. Indistinguishability obfuscation, if it could be built, would be able to hide not just collections of data but the inner workings of a computer program itself, creating a sort of cryptographic master tool from which nearly every other cryptographic protocol could be built. It is "one cryptographic primitive to rule them all," said Boaz Barak of Harvard University. But to many computer scientists, this very power made iO seem too good to be true. Computer scientists set forth candidate versions of iO starting in 2013. But the intense excitement these constructions generated gradually fizzled out, as other researchers figured out how to break their security. As the attacks piled up, "you could see a lot of negative vibes," said Yuval Ishai of the Technion in Haifa, Israel. Researchers wondered, he said, "Who will win: the makers or the breakers?" "There were the people who were the zealots, and they believed in [iO] and kept working on it," said Shafi Goldwasser, director of the Simons Institute for the Theory of Computing at the University of California, Berkeley. But as the years went by, she said, "there was less and less of those people." Now, Jain -- together with Huijia Lin of the University of Washington and Amit Sahai, Jain's adviser at UCLA -- has planted a flag for the makers. In a paper posted online on August 18, the three researchers show for the first time how to build indistinguishability obfuscation using only "standard" security assumptions. All cryptographic protocols rest on assumptions -- some, such as the famous RSA algorithm, depend on the widely held belief that standard computers will never be able to quickly factor the product of two large prime numbers. A cryptographic protocol is only as secure as its assumptions, and previous attempts at iO were built on untested and ultimately shaky foundations. The new protocol, by contrast, depends on security assumptions that have been widely used and studied in the past. "Barring a really surprising development, these assumptions will stand," Ishai said. While the protocol is far from ready to be deployed in real-world applications, from a theoretical standpoint it provides an instant way to build an array of cryptographic tools that were previously out of reach. For instance, it enables the creation of "deniable" encryption, in which you can plausibly convince an attacker that you sent an entirely different message from the one you really sent, and "functional" encryption, in which you can give chosen users different levels of access to perform computations using your data. The new result should definitively silence the iO skeptics, Ishai said. "Now there will no longer be any doubts about the existence of indistinguishability obfuscation," he said. "It seems like a happy end."' -- source: https://science.slashdot.org/story/20/11/10/1922225 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A laser projection mural in Christchurch goes slightly wrong, showing a Windows 10 message instead <https://www.theregister.com/2020/11/09/bork/>: There can be few of us who have not felt the clammy hand of a Windows update on our shoulder, but sticking it on a mural and declaring it "art"? That takes a New Zealander.

HP Replaces 'Free Ink for Life' Plan With '99 Cents a Month Or Your Printer Stops Working'
by Peter Reutemann 10 Nov '20

10 Nov '20

'In a new essay at EFF.org, Cory Doctorow re-visits HP's anti-consumer "security updates" that disabled third-party ink cartridges (while missing real vulnerabilities that could actually bypass network firewalls). Doctorow writes that it was just the beginning: HP's latest gambit challenges the basis of private property itself: a bold scheme! With the HP Instant Ink program, printer owners no longer own their ink cartridges or the ink in them. Instead, HP's customers have to pay a recurring monthly fee based on the number of pages they anticipate printing from month to month; HP mails subscribers cartridges with enough ink to cover their anticipated needs. If you exceed your estimated page-count, HP bills you for every page (if you choose not to pay, your printer refuses to print, even if there's ink in the cartridges). If you don't print all your pages, you can "roll over" a few of those pages to the next month, but you can't bank a year's worth of pages to, say, print out your novel or tax paperwork. Once you hit your maximum number of "banked" pages, HP annihilates any other pages you've paid for (but continues to bill you every month). Now, you may be thinking, "All right, but at least HP's customers know what they're getting into when they take out one of these subscriptions," but you've underestimated HP's ingenuity. HP takes the position that its offers can be retracted at any time. For example, HP's "Free Ink for Life" subscription plan offered printer owners 15 pages per month as a means of tempting users to try out its ink subscription plan and of picking up some extra revenue in those months when these customers exceeded their 15-page limit. But Free Ink for Life customers got a nasty shock at the end of last month: HP had unilaterally canceled their "free ink for life" plan and replaced it with "a $0.99/month for all eternity or your printer stops working" plan... For would-be robber-barons, "smart" gadgets are a moral hazard, an irresistible temptation to use those smarts to reconfigure the very nature of private property, such that only companies can truly own things, and the rest of us are mere licensors, whose use of the devices we purchase is bound by the ever-shifting terms and conditions set in distant boardrooms. From Apple to John Deere to GM to Tesla to Medtronic, the legal fiction that you don't own anything is used to force you to arrange your affairs to benefit corporate shareholders at your own expense. And when it comes to "razors and blades" business-model, embedded systems offer techno-dystopian possibilities that no shaving company ever dreamed of: the ability to use law and technology to prevent competitors from offering their own consumables. >From coffee pods to juice packets, from kitty litter to light-bulbs, the printer-ink cartridge business-model has inspired many imitators. HP has come a long way since the 1930s, reinventing itself several times, pioneering personal computers and servers. But the company's latest reinvention as a wallet-siphoning ink grifter is a sad turn indeed, and the only thing worse than HP's decline is the many imitators it has inspired.' -- source: https://hardware.slashdot.org/story/20/11/09/0221226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Tim Berners Lee's Startup Inrupt Releases Privacy Platform for Enterprises
by Peter Reutemann 10 Nov '20

10 Nov '20

'Inrupt, the startup from World Wide Web founder Tim Berners-Lee, announced an enterprise version of the Solid privacy platform today, which allows large organizations and governments to build applications that put users in control of their data . From a report: Berners-Lee has always believed that the web should be free and open, but large organizations have grown up over the last 20 years that make their money using our data. He wanted to put people back in charge of their data, and the Solid open source project, developed at MIT, was the first step in that process. Three years ago he launched Inrupt, a startup built on top of the open source project, and hired John Bruce to run the company. The two shared the same vision of shifting data ownership without changing the way websites get developed. With Solid, developers use the same standards and methods of building sites, and these applications will work in any browser. What Solid aims to do is alter the balance of data power and redirect it to the user. "Fast forward to today, and we're releasing the first significant technology as the fruits of our labor, which is an enterprise version of Solid to be deployed at scale by large organizations," Bruce explained. The core idea behind this approach is that users control their data in online storage entities called Personal Online Data Stores or Pods for short. The enterprise version consists of Solid Server to manage the Pods, and developers can build applications using an SDK to take advantage of the Pods and access the data they need to do a particular job like pay taxes or interact with a healthcare provider. Bruce points out that the enterprise version is fully compatible with the open source Solid project specifications. The company has been working with some major organizations prior to today's release including the BBC and National Health Service in the UK and the Government of Flanders in Belgium as they have been working to bring this to market.' -- source: https://yro.slashdot.org/story/20/11/09/1453252 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
