One of the most destructive botnets can now spread to nearby Wi-Fi networks
by Peter Reutemann 12 Feb '20

12 Feb '20

'Over the past half decade, the Emotet malware has emerged as a top Internet threat that pillages people’s bank accounts and installs other types of malware. The sophistication of its code base and its regularly evolving methods for tricking targets into clicking on malicious links—in September, for instance, it began a spam run that addresses recipients by name and quotes past emails they sent or received—has allowed it to spread widely. Now, Emotet is adopting yet another way to spread: using already compromised devices to infect devices connected to nearby Wi-Fi networks. World’s most destructive botnet returns with stolen passwords and email in tow Last month, Emotet operators were caught using an updated version that uses infected devices to enumerate all nearby Wi-Fi networks. It uses a programming interface called wlanAPI to profile the SSID, signal strength, and use of WPA or other encryption methods for password-protecting access. Then, the malware uses one of two password lists to guess commonly used default username and password combinations. After successfully gaining access to a new Wi-Fi network, the infected device enumerates all non-hidden devices that are connected to it. Using a second password list, the malware then tries to guess credentials for each user connected to the drive. In the event no connected users are infected, the malware tries to guess the password for the administrator of the shared resource.' -- source: https://arstechnica.com/information-technology/2020/02/one-of-the-most-dest… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

South Korea's Government Explores Move From Windows To Linux Desktop
by Peter Reutemann 11 Feb '20

11 Feb '20

'In May 2019, South Korea's Interior Ministry announced plans to look into switching to the Linux desktop from Windows. It must have liked what it saw. According to the Korean news site Newsis, the South Korean Ministry of Strategy and Planning has announced the government is exploring moving most of its approximately 3.3 million Windows computers to Linux. The reason for this is simple. It's to reduce software licensing costs and the government's reliance on Windows. As Choi Jang-hyuk, the head of the Ministry of Strategy and Finance, said, "We will resolve our dependency on a single company while reducing the budget by introducing an open-source operating system." How much? South Korean officials said it would cost 780 billion won (about $655 million) to move government PCs from Windows 7 to Windows 10. [...] Windows will still have a role to play for now on South Korean government computers. As the Aju Business Daily, a South Korean business news site, explained: Government officials currently use two physical, air-gapped PCs. One is external for internet use, and the other is internal for intranet tasks. Only the external one will use a Linux-based distro. Eventually, by 2026, most civil servants will use a single Windows-powered laptop. On that system, Windows will continue to be used for internal work, while Linux will be used as a virtual desktop via a Linux-powered cloud server. This looks to eventually end up as a Desktop-as-a-Service (DaaS) model. The report notes that the Ministry of National Defense and National Police Agency are already using the Ubuntu Linux 18.04 LTS-based Harmonica OS 3.0. "Meanwhile, the Korean Postal Service division is moving to TMaxOS," reports ZDNet. "The Debian Linux-based South Korean Gooroom Cloud OS is also being used by Defense and the Ministry of Public Administration and Security."' -- source: https://linux.slashdot.org/story/20/02/10/2133246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Companies That Buy Data Derived From Scraping the Contents of Your Email Inbox
by Peter Reutemann 11 Feb '20

11 Feb '20

'The popular Edison email app, which is in the top 100 productivity apps on the Apple app store, scrapes users' email inboxes and sells products based off that information to clients in the finance, travel, and e-Commerce sectors. The contents of Edison users' inboxes are of particular interest to companies who can buy the data to make better investment decisions, according to a J.P. Morgan document obtained by Motherboard. On its website Edison says that it does "process" users' emails, but some users did not know that when using the Edison app the company scrapes their inbox for profit. Motherboard has also obtained documentation that provides more specifics about how two other popular apps -- Cleanfox and Slice -- sell products based on users' emails to corporate clients. Some of the companies listed in the J.P. Morgan document sell data sourced from "personal inboxes," the document adds. A spokesperson for J.P. Morgan Research, the part of the company that created the document, told Motherboard that the research "is intended for institutional clients." That document describes Edison as providing "consumer purchase metrics including brand loyalty, wallet share, purchase preferences, etc." The document adds that the "source" of the data is the "Edison Email App." On the product section of its website, Edison offers "Edison Trends" and "Trends Direct." The company says it can provide "Detailed behavior patterns to improve your customers' experience and business results." Edison is just one of several companies that offer free email apps which then sell anonymized or pseudonymized data derived from users' inboxes. Another company that mines inboxes called Foxintelligence has data that comes from users of the Cleanfox app, which tidies up users' inboxes. Some of the "examples of clients" mentioned in a confidential Foxintelligence presentation include PayPal, consulting giants Bain & Company, and McKinsey & Company. "A spreadsheet containing data from Rakuten's Slice, an app that scrapes a user's inbox so they can better track packages or get their money back once a product goes down in price, contains the item that an app user bought from a specific brand, what they paid, and an unique identification code for each buyer," adds Motherboard. "An email obtained by Motherboard appeared to show the price for access to Rakuten data for one product category as over $100,000."' -- source: https://yro.slashdot.org/story/20/02/10/2158242 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Windows 10 Start Menu Now Harasses Firefox Users
by Peter Reutemann 11 Feb '20

11 Feb '20

'The "Suggested" section on the Windows 10 Start Menu used to just promote its own apps, reports MSPowerUser. But for some users (who haven't disable Microsoft's "Suggestions"), that menu is now showing a new kind of ad listing: The listing displays "Still using Firefox? Microsoft Edge is here", to all users of the former -- even with the latter already installed. The ad provides a link to download the chromium-based browser. Undoubtedly, the suggestions won't end here. Microsoft is reportedly planning to sprawl similar ads out to Wordpad, to encourage users to download official Office apps. The Windows Latest blog points out that Microsoft's "Suggestions" can be "permanently disabled with a few tweaks unlike the Chrome ads in Google search results."' -- source: https://news.slashdot.org/story/20/02/10/0014245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Suspicion and Anger Towards Microsoft Rises After Windows 10 Search Failure
by Peter Reutemann 10 Feb '20

10 Feb '20

'Earlier this week, searching in Windows 10 was broken, "with a black bar showing where search results should be, even for those who tried to perform a local search of their files." Microsoft issued a fix and blamed the issue on a "third-party networking fiber provider". But unfortunately, Microsoft's fix isn't working for everyone -- and that's just the beginning. Long-time Slashdot reader Futurepower(R) shares Forbes' report: Second, and more worryingly, Microsoft's explanation doesn't add up and it has prompted serious questions to be asked about how the operating system works and what personal data it is sharing. Popular Microsoft pundit Woody Leonard led the charge, writing: "If you believe that yesterday's worldwide crash of Windows 10 Search was caused by a bad third-party fiber provider, I have a bridge to sell you." In an open letter to new Windows head Panos Panay, Susan 'Patch Lady' Bradley was similarly sceptical, noting that today "we all found out that our local search boxes are somehow dependent on some service working at Microsoft." She attacked the company for a lack of transparency and gave it a maximum 'Pinocchio score' for a lack of trust... Similarly, Engadget writer Richard Lawler revealed that users were now trying to hack the Windows 10 registry to disconnect their local file searches from Microsoft servers "and I can't say I blame them after this episode. Microsoft owes users a better explanation than this and should make sure it's impossible for offline features to get taken out when the cloud is having an issue." In fact, Forbes writes that "the aforementioned Windows 10 registry hack appears to be the only 100% fix for this issue and it also disconnects Bing and Cortana online services from Windows 10 search." And then on Saturday the Windows Latest blog also noticed that Microsoft's release notes for Windows 10 20H1 Build 19035 reveal that Microsoft is apparently now delaying the roll-out of a widely-anticipated "Optional Updates" option. "It appears that the new Optional updates experience will come out in October/November 2020, not this spring as previously planned."' -- source: https://tech.slashdot.org/story/20/02/09/2241212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel's 'Clear Linux' Distro Beats Ubuntu and Windows 10 -- on an AMD Laptop
by Peter Reutemann 10 Feb '20

10 Feb '20

'Intel's Clear Linux distribution looks like it could be the best operating system to run on cheap AMD hardware, with benchmarks showing it outperforms Windows 10 and Ubuntu on a $199 laptop with a budget AMD Ryzen 3200U processor. The Phoronix website ran a series of benchmarks on a super-cheap AMD laptop from Walmart, and found that Intel Clear Linux beat popular Linux distros Fedora and Ubuntu for 78% of the tests. Not only is it remarkable that a relatively unknown Linux distro is so easily outperforming established operating systems, the fact that Intel is the company behind the distro is particularly ironic. As you can imagine, Clear Linux is optimized for Intel processors, but it seems like it works brilliantly on AMD hardware as well.' -- source: https://linux.slashdot.org/story/20/02/08/1849207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Almost Every Website You Visit Records Exactly How Your Mouse Moves
by Peter Reutemann 09 Feb '20

09 Feb '20

'Medium's technology blog OneZero reports that many websites today use a service that collects all of your mouse movements, enabling "replays" of every move. "What surprised me was that the software even recorded when I shook my mouse around while deciding what to click on. It felt like observing digital body language." Session replay services have been around for over a decade and are widely used. One service, called FullStory, lists popular sites like Zillow, TeeSpring, and Jane as clients on its website. Another, called LogRocket, boasts Airbnb, Reddit, and CarFax, and a third called Inspectlet lists Shopify, ABC, and eBay among its users. They bill themselves as tools for designing sites that are easy to use and increase desired user behavior, such as buying an item. If many users add items to their cart, but then abandon the purchase at a certain rough part of the checkout process, for instance, the service helps site owners figure out how to change the site's design to nudge users over the checkout line... FullStory even has a feature that tracks what it calls "rage clicks." This is when a user gets frustrated with a site and starts angrily clicking over and over. In a semi-related story, a reporter for The Markup also recently discovered Amazon had apparently collected 90,000 rows of timestamped data about every tap they'd made on their Kindle.' -- source: https://yro.slashdot.org/story/20/02/08/002242 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Elementary OS Wants to Crowdfund a Better Distro-Independent 'AppCenter for Everyone'
by Peter Reutemann 09 Feb '20

09 Feb '20

'In 2017 Elementary OS built a pay-what-you-want app store -- funded with $10,000 raised on IndieGogo. Now they're trying to raise another $10,000 for a one-week, in-person sprint in Denver, Colorado, Forbes reports, to upgrade the store while bringing an even grander concept to reality: That concept comprises 4 main goals: - Enable open source developers to monetize their apps on every other Linux distribution - Empower developers to ship apps with cutting-edge technologies - Improve privacy, security, and stability - Streamline the payments process On the technical side of things, the team plans to rebuild AppCenter's backend from the ground up to enable newer technologies developers are asking for, and they're rallying behind the Flatpak packaging format to get it done. They've already been collaborating with the FlatHub team, and plan to bring in developers from Endless and GNOME to ensure that "our solution can be reused and improved by other Flatpak stores and the greater open source desktop ecosystem." For a donation of $10, "you'll have your name immortalized in the AppCenter code on GitHub," explains a promotional video. (There's already 70 backers who have claimed this perk.) In fact, "Less than 8 hours ago we launched #AppCenterForEveryone, and we're 50% funded," announced an update Friday on Twitter. The campaign's web page shared this note of appreciation. "With your support, we'll be able to accelerate the timeline on adopting cutting edge technology and making an even more competitive Open Source operating system and a compelling foundation for all Flatpak stores."' -- source: https://linux.slashdot.org/story/20/02/08/1813251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Security In 2020: Revisited
by Lawrence D'Oliveiro 08 Feb '20

08 Feb '20

Security guru Bruce Schneier revisits <https://www.schneier.com/blog/archives/2020/02/security_in_202_1.html> an essay he wrote 10 years ago, looking ahead in security-related computing trends. If you can stomach the neologisms: Trend over the decade up to 2010: * deperimeterization -- the realization that securing the boundary isn’t enough, you have to have defence in depth. Also known as “submarine warfare”. Trends already becoming apparent in 2010: * consumerization -- the idea that computing needs in workplaces will be following the trends in consumer devices, not leading them * decentralization -- or rather, recentralization in the cloud Trends he forecast in 2010: * deconcentration -- the replacement of general-purpose computers with special-purpose devices. But he also includes special-purpose apps installed on more general-purpose devices like smartphones. * decustomerization -- the idea that we get more of our IT functionality without any business relationship. But beware the maxim: “if you’re not paying for the product, then you are the product”. Also this has been tried with hardware before without success, but he thinks it’s something that will be tried again. * depersonization -- software agents taking decisions on your behalf. Gadgets in your house (and your car) won’t even need you to manage them.

Google Fixes No-User-Interaction Bug In Android's Bluetooth Component
by Peter Reutemann 08 Feb '20

08 Feb '20

'Google has patched this week a critical security flaw in Android's Bluetooth component. If left unpatched, the vulnerability can be exploited without any user interaction and can even be used to create self-spreading Bluetooth worms. Researchers said that exploiting the bug requires no user interaction. All that is required is that the user has Bluetooth enabled on his device. However, while this requirement would have limited the attack surface in past years, it does not today since modern Android OS versions ship with Bluetooth enabled by default and many Android users use Bluetooth-based headphones meaning the Bluetooth service is likely to be enabled on many handsets. The bug can lead to remote code execution and the hijacking of a device. Fixes for the bug are available via the Android February 2020 Security Bulletin, which has been available for download starting this week. Android 9 and earlier are impacted.' -- source: https://tech.slashdot.org/story/20/02/07/0220203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Does Badly
by Lawrence D'Oliveiro 04 Feb '20

Kind of fun to read this report <https://www.aljazeera.com/ajimpact/alphabet-shares-fall-google-misses-sales…>, saying Google’s parent company Alphabet had its “worst fourth-quarter revenue growth since 2015”. Then you look at the numbers, showing ad revenue was up about 17% year-on-year, and while costs also went up: That left profit of $10.67bn, or $15.35 per share, compared with the analysts' average estimate of $8.787bn, or $12.53 per share. That’s right, Google was substantially *more* profitable than analysts were expecting. And yet its share price still apparently fell 3% after the news came out. That’s Wall Street for you...

A Reminder Of Why Removable Disk Packs Went Out Of Fashion
by Lawrence D'Oliveiro 04 Feb '20

04 Feb '20

Tricky things, removeable storage devices. Requiring fine tolerances between medium and drive is just asking for trouble. Here <https://www.theregister.co.uk/2020/02/03/who_me/> is a story of how a crash in one removeable 1960s-era unit ended up destroying a whole string of disk drives. I can remember also reading, in an old Computer Centre bulletin from an Australian university archived on Bitsavers, an item on their policy on removeable drive cartridges: you could only use cartridges allocated by them, you were not allowed to bring in cartridges from elsewhere. A similar thing happened to me, when the Zip drive in my 1998-vintage PowerMac G3 developed the infamous “click of death”, I only killed a couple of cartridges before I realized I should never use that drive again. Nowadays we have SD cards and hot-pluggable USB drives, which are a bit more robust against such failure modes. Or are they ... ?

Cringely Predicts IBM 'Disappears Into Red Hat'
by Peter Reutemann 03 Feb '20

03 Feb '20

'Tech pundit Robert X. Cringely has been sharing technology predictions every January for over two decades -- and he made another big one on Friday: IBM has three divisions — Global Technology Services (GTS), Global Business Services (GBS), and Red Hat. GTS is the legacy IT business, GBS is the professional services business invented by Lou Gerstner to save IBM the last time it was in huge trouble, and Red Hat is Linux. GTS — that part of IBM most of us still think of as IBM — will probably be sold by summer. Either it will go to private equity (depends on the total debt load) or it will be sold to HPE or maybe to Oracle. Either way, it's not a likely success story, but [current CEO Ginni] Rometty has no real choice. IBM is, at this point, smoke, mirrors, and buybacks. The GTS windfall will land in Ginni's final quarter, juicing her payout, which might be the major point of the deal... IBM's new CEO is Arvind Krishna, formerly head of the Cognitive Computing unit — IBM's cloud guy. Except Cognitive Computing was never really cloud. Cognitive has been a mishmash of cloud, supported by revenue streams that are anything but cloud. It's cloud in name only and will be the part that goes next summer, possibly with Mr. Krishna still at its head. The next chairman of IBM after Rometty will be current Red Hat CEO Jim Whitehurst. If Whitehurst is as smart as I think he is, he started yesterday looking for a new job. It's not that he really intends to leave, but as the next savior of IBM, Ginni et al will pay anything to keep him. Cut your new deal now, Jim, while demand is greatest....Whitehurst will turn IBM into Red Hat, which will take HQ to North Carolina and mean most of the remaining GBS staff will be gone in a year... It still won't save IBM. They'll go down in the coming year or two along with the rest of the industry we used to call IT... Let's just say that IBM's loss is AWS's gain.' -- source: https://linux.slashdot.org/story/20/02/02/0448233 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

MIT Numerical Courses Moving From MATLAB To Julia
by Lawrence D'Oliveiro 03 Feb '20

03 Feb '20

Came across this <https://github.com/mitmath/julia-mit> repo, which is an intro to the Julia language. Apparently this is increasingly being used in place of MATLAB in numerical-computation courses at MIT. Why not Python? Because it is fine as long as you can use existing computational kernels, but as soon as you need custom ones, it gets slow if you do them in Python, or requires special skills to write them in C or Fortran, and make them callable from Python. Julia incorporates a “just-in-time” compiler using LLVM to achieve speed close to that of C in this case. Why not MATLAB? Because it is proprietary: Unlike Matlab, [Julia] is free/open-source software, which eliminates licensing headaches and allows you to look inside the Julia implementation to see how it works (since Julia is mostly written in Julia, its code is much more readable than a language like Python that is largely implemented in low-level C). They do like using Julia in Jupyter notebooks. I see a few .ipynb files in the repos for other courses (along with a few .pptx ones as well, unfortunately). Also several “.jmd” files, which look like some variety of markdown.

So to get a comparable range of TV content to that you currently have free-to-air, you are going to have to subscribe to two or three or maybe more different streaming services. The increasing multitude of things to pay for isn’t about choice, but about no choice at all.

Should Huawei Just Abandon Android?
by Peter Reutemann 03 Feb '20

03 Feb '20

'Due to a U.S. government ban on sales to Huawei, Google revoked its license for popular apps last spring (including Gmail and the Play Store). But this week Huawei executive Fred Wangfei suggested that even if that ban is lifted, Huawei would continue developing its own app ecosystem instead to avoid the possibility of future political complications. The vice president of risk management and partner relations at Huawei later called those remarks "incorrect," while elsewhere Huawei issued a slightly different statement -- that "An open Android ecosystem is still our first choice, but if we are not able to continue to use it, we have the ability to develop our own." But BGR was already noting that Huawei "is ready to invest $3 billion this year to incentivize more than 4,000 developers to improve its Huawei Mobile Services system. Another billion is reserved for marketing purposes." And Android Authority suggests Huawei should stick to its original statement. "Maybe it's time for Huawei to go all-in on Harmony OS and do what it can to bring a viable alternative to Android and iOS..." If there's any company today that has the financial resources and raw talent necessary to bring in a viable third choice for smartphone operating systems, it's Huawei... Sure, it would be a long-term investment and there would inevitably be short-term losses as the company tries to find its footing and develop Harmony OS to have its own identity. But it would prevent something like the Huawei ban from happening to the company again as well as further the company's ambitions as not only a smartphone manufacturer but as a technology creator.... Huawei would have major difficulties in encouraging wide adoption of Harmony OS for one major reason: it's Huawei. The Huawei ban exists because the United States government doesn't trust Huawei and there are numerous (as yet unproven) accusations against the company related to espionage, IP theft, fraud, and even violations of international treaties... Huawei is already in a bad situation. It's going to need to dig itself out of the hole it's in regardless, so why not use this opportunity to turn lemons into lemonade and develop Harmony OS as a viable third option on the way? Maybe the industry needs a shake-up... Maybe a new operating system is just the kind of fire OEMs need to turn the market around. Maybe a real, potent threat that the billions of people who use Android and iOS just might jump ship to something else would scare companies into taking some real risks. As I said earlier, there aren't too many companies out there right now that could do this, but Huawei could.

Linus Torvalds Pulls WireGuard VPN into Linux 5.6 Kernel Source Tree
by Peter Reutemann 02 Feb '20

02 Feb '20

'"The WireGuard VPN protocol will be included into the next Linux kernel as Linus Torvalds has merged it into his source tree for version 5.6," reports TechRadar: While there are many popular VPN protocols such as OpenVPN, WireGuard has made a name for itself by being easy to configure and deploy as SSH... The WireGuard protocol is a project from security researcher and kernel developer Jason Donenfeld who created it as an alternative to both IPsec and OpenVPN. Since the protocol consists of around just 4,000 lines of code as opposed to the 100,000 lines of code that make up OpenVPN, it is much easier for security experts to review and audit for vulnerabilities. While WireGuard was initially released for the Linux kernel, the protocol is now cross-platform and can be deployed on Windows, macOS, BSD, iOS and Android. Ars Technica notes that with Linus having merged WireGuard into the source tree, "the likelihood that it will disappear between now and 5.6's final release (expected sometime in May or early June) is vanishingly small." WireGuard's Jason Donenfeld is also contributing AVX crypto optimizations to the kernel outside the WireGuard project itself. Specifically, Donenfeld has optimized the Poly1305 cipher to take advantage of instruction sets present in modern CPUs. Poly1305 is used for WireGuard's own message authentication but can be used outside the project as well — for example, chacha20-poly1305 is one of the highest-performing SSH ciphers, particularly on CPUs without AES-NI hardware acceleration. Other interesting features new to the 5.6 kernel will include USB4 support, multipath TCP, AMD and Intel power management improvements, and more.' -- source: https://it.slashdot.org/story/20/02/01/1846256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

OpenBSD Mail Server Bug Allowed Remotely Executing Shell Commands As Root
by Peter Reutemann 02 Feb '20

02 Feb '20

'This week a remotely-exploitable vulnerability (granting root privileges) was discovered in OpenSMTPD (OpenBSD's implementation of server-side SMTP). ZDNet notes that the library's "portable" version "has also been incorporated into other OSes, such as FreeBSD, NetBSD, and some Linux distros, such as Debian, Fedora, Alpine Linux, and more." To exploit this issue, an attacker must craft and send malformed SMTP messages to a vulnerable server... OpenSMTPD developers have confirmed the vulnerability and released a patch earlier Wednesday -- OpenSMTPD version 6.6.2p1... The good news is that the bug was introduced in the OpenSMTPD code in May 2018 and that many distros may still use older library versions, not affected by this issue. For example, only in-dev Debian releases are affected by this issue, but not Debian stable branches, which ship with older OpenSMTPD versions. Technical details and proof of concept exploit code are available in the Qualys CVE-2020-7247 security advisory. Hackaday has a more detailed description of the vulnerability, while the Register looks at the buggy C code. Interestingly, Qualys researchers exploited this vulnerability using a technique from the Morris Worm of 1988.' -- source: https://it.slashdot.org/story/20/02/01/2254237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Moves To Monetize Thunderbird, Transfers Project To New Subsidiary
by Peter Reutemann 31 Jan '20

31 Jan '20

'The Mozilla Foundation announced today that it was moving its Thunderbird email client to a new subsidiary named the MZLA Technologies Corporation. From a report: Mozilla said that Thunderbird will continue to remain free and open source, but by moving the project away from its foundation into a corporate entity they will be able to monetize the product and pay for its development easier than before. Currently, Thunderbird is primarily being kept alive through charitable donations from the product's userbase. "Moving to MZLA Technologies Corporation will not only allow the Thunderbird project more flexibility and agility, but will also allow us to explore offering our users products and services that were not possible under the Mozilla Foundation," said Philipp Kewisch, Mozilla Product Manager. "The move will allow the project to collect revenue through partnerships and non-charitable donations, which in turn can be used to cover the costs of new products and services," Kewisch added.' -- source: https://tech.slashdot.org/story/20/01/29/1430253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

64-Bit Times On 32-Bit Linux
by Lawrence D'Oliveiro 31 Jan '20

31 Jan '20

Some more patches have gone into the Linux kernel <https://www.theregister.co.uk/2020/01/30/linux_5_6_2038/> to allow 32-bit builds to deal with times past the year-2038 barrier. Basically the fix involves offering a 64-bit alternative to the original time_t type, without the whole app having to go 64-bit. One point I noticed is that certain filesystems (e.g. ext2, presumably ext3 as well) store on-disk fields with 32-bit timestamps, so if you’re using one of these, you’ll have to reformat the disks as well. And that would apply even if you’re already using a 64-bit OS.

autoremove
by john 29 Jan '20

29 Jan '20

Hi all, At our last meeting Tom was concerned about Linux bloating with surplus files. I have always found this to seldom be the case due to : a. The new download removes the older files or: b. The command autoremove clears the unused kernels and other not required files. eg. john(a)polomint:~$ sudo apt autoremove Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be REMOVED: linux-headers-4.15.0-72 linux-headers-4.15.0-72-generic linux-image-4.15.0-72-generic linux-modules-4.15.0-72-generic linux-modules-extra-4.15.0-72-generic 0 upgraded, 0 newly installed, 5 to remove and 4 not upgraded. After this operation, 332 MB disk space will be freed. Do you want to continue? [Y/n] Cheers John..

Intel Is Patching Its 'Zombieload' CPU Security Flaw For the Third Time
by Peter Reutemann 28 Jan '20

28 Jan '20

'For the third time in less than a year, Intel has disclosed a new set of vulnerabilities related to the speculative functionality of its processors. On Monday, the company said it will issue a software update "in the coming weeks" that will fix two more microarchitectural data sampling (MDS) or Zombieload flaws. This latest update comes after the company released two separate patches in May and November of last year. Compared to the MDS flaws Intel addressed in those two previous patches, these latest ones have a couple of limitations. To start, one of the vulnerabilities, L1DES, doesn't work on Intel's more recent chips. Moreover, a hacker can't execute the attack using a web browser. Intel also says it's "not aware" of anyone taking advantage of the flaws outside of the lab. In response to complaints of the company's piecemeal approach, Intel said that it has taken significant steps to reduce the danger the flaws represent to its processors. "Since May 2019, starting with Microarchitectural Data Sampling (MDS), and then in November with TAA, we and our system software partners have released mitigations that have cumulatively and substantially reduced the overall attack surface for these types of issues," a spokesperson for the company said. "We continue to conduct research in this area -- internally, and in conjunction with the external research community.' -- source: https://it.slashdot.org/story/20/01/27/2126231 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

European Processor Initiative
by Lawrence D'Oliveiro 28 Jan '20

28 Jan '20

Here’s a report <https://www.nextplatform.com/2020/01/27/european-processor-initiative-readi…> on a Europe-wide effort to produce a processor chip for an “exascale” supercomputer. It will have an ARM CPU core, with a RISC-V-based accelerator and a few other special-purpose units on the side. I was intrigued to see mention of an “AI-inspired bfloat16 format”. Floating-point numbers commonly come in 32-bit and 64-bit sizes. There is also a “half-precision” 16-bit format, with reduced precision and dynamic range, commonly used in computer graphics, for example. This new format keeps the full dynamic range of 32-bit floats, at the expense of even further reduced precision. Apparently this works better for various machine-learning algorithms.

ProtonVPN Open Sources All Its Code
by Peter Reutemann 28 Jan '20

28 Jan '20

'ProtonVPN open sourced its code this week, ZDNet reports: On Tuesday, the virtual private network (VPN) provider, also known for the ProtonMail secure email service, said that the code backing ProtonVPN applications on every system -- Microsoft Windows, Apple macOS, Android, and iOS -- is now publicly available for review in what Switzerland-based ProtonVPN calls "natural" progression. "There is a lack of transparency and accountability regarding who operates VPN services, their security qualifications, and whether they fully conform to privacy laws like GDPR," the company says. "Making all of our applications open source is, therefore, a natural next step." Each application has also undergone a security audit by SEC Consult, which ProtonVPN says builds upon a previous partnership with Mozilla... The source code for each app is now available on GitHub (Windows, macOS, Android, iOS). "As a community-supported organization, we have a responsibility to be as transparent, accountable, and accessible as possible," ProtonVPN says. "Going open source helps us to do that and serve you better at the same time." They're also publishing the results of an independent security audit for each app. "As former CERN scientists, publication and peer review are a core part of our ethos..." the company wrote in a blog post. They also point out that Switzerland has some of the world's strongest privacy laws -- and that ProtonVPN observes a strict no-logs policy. But how do they feel about their competition? "Studies have found that over one-third of Android VPNs actually contain malware, many VPNs suffered from major security lapses, and many free VPN services that claimed to protect privacy are secretly selling user data to third parties."' -- source: https://yro.slashdot.org/story/20/01/27/0352244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Do Emails Contribute to Global Warming?
by Peter Reutemann 28 Jan '20

28 Jan '20

'"Cut back on email if you want to fight global warming," read the headline on a recent article at Bloomberg: [A]ll those messages require energy to preserve them. And despite the tech industry's focus on renewables, the advents of streaming and artificial intelligence are only accelerating the amount of fossil fuels burned to keep data servers up. Right now, data centers consume about 2 percent of the world's electricity, but that is expected to reach 8 percent by 2030. Moreover, only about 6 percent of all data ever created is in active use today, according to research from Hewlett Packard Enterprise. That means 94 percent is sitting in a vast "landfill" with a massive carbon footprint. "It's costing us the equivalent of maintaining the airline industry for data we don't even use," said Andrew Choi, a senior research analyst at Parnassus Investments, a $27 billion environmental, social and governance firm in San Francisco. Kirk Bresniker, chief architect of Hewlett Packard Labs, said these server farms use energy both to retain your data and when you use it... And when you empty the email trash, you probably aren't actually erasing the data. Multiple copies of even decade-old emails are stored on servers around the world, still using energy... Bresniker says the tech industry is "flying blind" when it comes to the true cost of storing data. The picture is clouded by a constant stream of efficiency and memory upgrades, increased renewable power and AI aimed at data-center efficiency. "We don't really understand what the footprint is," he said... The sum of all the world's data in 2018 was 33 zettabytes — 33 trillion gigabytes — but by 2025 it could increase fivefold, to 175 zettabytes, according to International Data Corp. Every day, the world produces about 2.5 quintillion bytes of data... Computing workloads are likely to more than double as more AI comes online, more devices are connected and people do more work in the cloud... Choi says the problem is getting too big, too fast... Training an AI model emits about as much carbon as the lifetime emissions associated with running five cars' -- source: https://hardware.slashdot.org/story/20/01/27/0149253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Leaked Documents Expose the Secretive Market for Your Web Browsing Data
by Peter Reutemann 28 Jan '20

28 Jan '20

'An antivirus program used by hundreds of millions of people around the world is selling highly sensitive web browsing data to many of the world's biggest companies, a joint investigation by Motherboard and PCMag has found. From the report: Our report relies on leaked user data, contracts, and other company documents that show the sale of this data is both highly sensitive and is in many cases supposed to remain confidential between the company selling the data and the clients purchasing it. The documents, from a subsidiary of the antivirus giant Avast called Jumpshot, shine new light on the secretive sale and supply chain of peoples' internet browsing histories. They show that the Avast antivirus program installed on a person's computer collects data, and that Jumpshot repackages it into various different products that are then sold to many of the largest companies in the world. Some past, present, and potential clients include Google, Yelp, Microsoft, McKinsey, Pepsi, Sephora, Home Depot, Conde Nast, Intuit, and many others. Some clients paid millions of dollars for products that include a so-called "All Clicks Feed," which can track user behavior, clicks, and movement across websites in highly precise detail.' -- source: https://yro.slashdot.org/story/20/01/27/1453226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Has Banned Nearly 200 Malicious Firefox Add-ons Over the Last Two Weeks
by Peter Reutemann 28 Jan '20

28 Jan '20

'Over the past two weeks, Mozilla's add-on review team has banned 197 Firefox add-ons that were caught executing malicious code, stealing user data, or using obfuscation to hide their source code. From a report: The add-ons have been banned and removed from the Mozilla Add-on (AMO) portal to prevent new installs, but they've also been disabled in the browsers of the users who already installed them. The bulk of the ban was levied on 129 add-ons developed by 2Ring, a provider of B2B software. The ban was enforced because the add-ons were downloading and executing code from a remote server. According to Mozilla's rules, add-ons must self-contain all their code, and not download code dynamically from remote locations. Mozilla has recently begun strictly enforcing this rule across its entire add-on ecosystem. A similar ban for downloading and executing remote code in users' Firefox browsers was also levied against six add-ons developed by Tamo Junto Caixa, and three add-ons that were deemed fake premium products (their names were not shared).' -- source: https://news.slashdot.org/story/20/01/27/1646207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux on laptops: Ubuntu 19.10 on the HP Dragonfly Elite G1
by Peter Reutemann 28 Jan '20

28 Jan '20

'Last month, Ars Associate Reviewer Valentina Palladino treated us to a thorough hands-on review of HP's ultra-sleek, ultra-chic Dragonfly Elite G1. Shortly afterward at CES, HP announced a second-generation Dragonfly Elite, the G2, with Ice Lake CPU, optional LTE modem, and more. We haven't had a chance to get our hands on the G2 yet—but while we wait, we wanted to evaluate the Elite G1 not only with the OEM Windows it ships with, but with a fresh Linux installation. We can't evaluate a laptop with every possible Linux distribution, but in the case of noteworthy designs like the Dragonfly Elite, we want to at least see if one of the more popular distros installs cleanly, detects all the hardware, and is a good daily driver. Our first try was Ubuntu 18.04.3, "Bionic Beaver," the most recent Long Term Support release of Ubuntu. For the most part, the installation went well—the keyboard and touchpad were responsive, the screen looked fine, and so forth—but unfortunately, the Intel Wi-Fi chipset used in the Dragonfly Elite is new enough that 18.04.3 doesn't have an in-kernel driver. If you're a hardcore Linux type, that might not be enough to stop you—you have many possible options, such as installing a backported newer version of the Linux kernel—but we wanted to see if we could get a "just works" experience rather than a "percussive maintenance required" experience, so we regretfully shelved Ubuntu 18.04.3 and went to the newest interim Ubuntu release—October 2019's 19.10 "Eoan Ermine." Again, the actual installation went fine—but this time, we have Wi-Fi as well without touching a thing.

Librem 5 phone hands-on—Open source phone shows the cost of being different
by Peter Reutemann 26 Jan '20

26 Jan '20

'It is hard to do something truly different in the smartphone industry. Companies, especially smaller companies, are all working from the same parts bin with the same manufacturing partners. You take your Qualcomm SoC, your Samsung display, and your Sony camera sensor—and you take a flight to China and visit Foxconn, which, in addition to manufacturing, will even do engineering for you if you want. Smartphones are so samey because they have an established, for-hire supply chain that has a certain way of doing things, and it's much cheaper, faster, and easier if you just "go with the flow" and do what everyone else is doing. Big companies like Samsung and Apple have enough money, control, and connections to move the supply chain in whatever direction they want. In terms of smaller companies, though, there is a single one trying to blaze its own path: Purism, the maker of open source Linux laptops, is building the Librem 5 smartphone. Not only is the OS open source and based on GNU/Linux—not Android—the hardware is open source, too. The core components have open source firmware, and there are even public hardware schematics. This is as close as you're going to get to a totally open source smartphone. If you haven't noticed, open source smartphone hardware is not a thing that existed before now. There have been phones that run open source builds of Android, but those are full of closed-source firmware from non-open components. The usual hardware companies cautiously guard their hardware designs and drivers, and Purism's hardline stance on open source has ruled out almost the entire established smartphone supply chain. As the company writes in a blog post, "When we first approached hardware manufacturers almost two years ago with this project most of them instantly said 'No, sorry, impossible, we can not help you'." Others warned us, that it could never work, that it was too complicated, 'the industry does not do that,' and so forth." What followed was a long and winding road, but after two years of work, Purism is finally shipping the Librem 5 smartphones to customers. We were able to spend a few days with a device, and it's definitely one of the most unusual smartphones in recent memory. The thing to keep in mind here is that Purism has taken on an absolutely gargantuan task. It somehow scraped together a new supply chain of mostly open source components, it came up with a smartphone design from scratch, and it is building its own smartphone distribution of Linux. Two years is not enough time to do this. The OS and app package is not nearly finished, and it lacks basic smartphone functionality. The hardware is nearly finished, but you'll have a hard time taking advantage of it right now since the power management isn't really implemented, and support for things like the cameras are non-existent. If you really want open source smartphones to be a thing, though, this is where you need to start. The Librem 5 is a proof of concept.' -- source: https://arstechnica.com/gadgets/2020/01/librem-5-phone-hands-on-a-proof-of-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel CPU Chip Shortages
by Lawrence D'Oliveiro 24 Jan '20

24 Jan '20

This article <https://www.theregister.co.uk/2020/01/20/intel_hpe_xeon_shortage/> talks about the shortage of Intel server chips. But it also mentions that Intel’s attempts to crank up production of these is “to the detriment of desktop and mobile parts”. So there are shortages of CPU chips all round, and AMD is benefiting somewhat from this. Who is buying most of these server chips? It appears it’s not actual hardware vendors like Dell, HP etc, who apparently only buy about half a million CPUs per year each. These are dwarfed by “hyperscaler” companies that are named by one commenter as Alibaba, AWS, Azure, Baidu, Facebook, Google and Tencent, each taking over a million CPUs per year.

Apple's Privacy Software Allowed Users To Be Tracked, Says Google
by Peter Reutemann 23 Jan '20

23 Jan '20

'Google researchers have exposed details of multiple security flaws in its rival Apple's Safari web browser that allowed users' browsing behavior to be tracked, despite the fact that the affected tool was specifically designed to protect their privacy. From a report: The flaws, which were ironically found in an anti-tracking feature known as Intelligent Tracking Prevention, were first disclosed by Google to Apple in August last year. In a soon-to-be published paper seen by the Financial Times, researchers in Google's cloud team have since identified five different types of potential attack that could have resulted from the vulnerabilities, allowing third parties to obtain "sensitive private information about the user's browsing habits." "You would not expect privacy-enhancing technologies to introduce privacy risks," said Lukasz Olejnik, an independent security researcher who has seen the paper. "If exploited or used, [these vulnerabilities] would allow unsanctioned and uncontrollable user tracking. Apple rolled out Intelligent Tracking Prevention in 2017, with the specific aim of protecting Safari browser users from being tracked around the web by advertisers' and other third-parties' cookies.' -- source: https://tech.slashdot.org/story/20/01/22/2119245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Reuters: Apple cut backup end-to-end encryption plans after FBI complained
by Peter Reutemann 22 Jan '20

22 Jan '20

'Two years ago, Apple dropped a plan that would have made it impossible for the company to decrypt iPhone and iPad backups for law enforcement, according to a Reuters report today. Reuters wrote that "six sources familiar with the matter" confirmed that Apple dropped the end-to-end encryption plan for iCloud Backup "after the FBI complained that the move would harm investigations." Apple had "told the FBI that it planned to offer users end-to-end encryption when storing their phone data on iCloud" more than two years ago, Reuters wrote. "Under that plan, primarily designed to thwart hackers, Apple would no longer have a key to unlock the encrypted data, meaning it would not be able to turn material over to authorities in a readable form even under court order," the report continued. But the FBI objected, and Apple dropped the plan, although the exact reason for doing so isn't clear. One former Apple employee told Reuters that the company "decided they weren't going to poke the bear anymore." However, another former Apple employee "said it was possible the encryption project was dropped for other reasons, such as concern that more customers would find themselves locked out of their data more often."' -- source: https://arstechnica.com/tech-policy/2020/01/apple-reportedly-nixed-plan-for… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Notorious Crime Gang Targets Internet Routers Using Tomato Firmware
by Peter Reutemann 22 Jan '20

22 Jan '20

'Internet routers running the Tomato alternative firmware are under active attack by a self-propagating exploit that searches for devices using default credentials. When credentials are found, the exploit then makes the routers part of a botnet that's used in a host of online attacks, researchers said on Tuesday. The Muhstik botnet came to light about two years ago when it started unleashed a string of exploits that attacked Linux servers and Internet-of-things devices. It opportunistically exploited a host of vulnerabilities, including the so-called critical Drupalgeddon2 vulnerability disclosed in early 2018 in the Drupal content management system. Muhstik has also been caught using vulnerabilities in routers that use Gigabit Passive Optical Network (GPON) or DD-WRT software. The botnet has also exploited previously patched vulnerabilities in other server applications, including the Webdav, WebLogic, Webuzo, and WordPress. On Tuesday, researchers from Palo Alto Networks said they recently detected Muhstik targeting Internet routers running Tomato, an open-source package that serves as an alternative to firmware that ships by default with routers running Broadcom chips. The ability to work with virtual private networks and provide advanced quality of service control make Tomato popular with end users and in some cases router sellers. The exploits use already infected devices to scan the Internet for Tomato routers and, when found, to check if they use the default username and password of "admin:admin" or "root:admin" for remote administration. The exploit causes Tomato routers that haven't been locked down with a strong password to join an IRC server that's used to control the botnet. The infection also causes the routers to scan the Internet for servers or devices running WordPress, Webuzo, or WebLogic packages that are vulnerable.' -- source: https://it.slashdot.org/story/20/01/21/2039246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

14% of Android App Privacy Policies Contain Contradictions About Data Collection
by Peter Reutemann 22 Jan '20

22 Jan '20

'A large number of Android mobile apps listed on the official Google Play Store contain self-contradictory language in their privacy policies in regards to data collection practices. From a report: In an academic study published last year, researchers created a tool named PolicyLint that analyzed the language used in the privacy policies of 11,430 Play Store apps. They found that 14.2% (1,618 apps) contained a privacy policy with logical contradicting statements about data collection. Examples include privacy policies that stated in one section that they do not collect personal data, only to contradict themselves in subsequent sections, where they state they collect emails or customer names -- which are clearly personally-idenfiable information. While the research team could not determine the app maker's intent in using contradicting statements in their privacy policy, researchers feel the primary purpose was to mislead users if they ever took the time to read the policies.' -- source: https://yro.slashdot.org/story/20/01/21/188216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Why This Time The New Browser Wars Are Different
by Peter Reutemann 21 Jan '20

21 Jan '20

'The Verge argues that the browser wars "are back, but it's different this time." The mobile web is broken and unfettered tracking and data sharing have made visiting websites feel toxic, but since the ecosystem of websites and ad companies can't fix it through collective action, it falls on browser makers to use technological innovations to limit that surveillance, however each company that makes a browser is taking a different approach to creating those innovations, and everybody distrusts everybody else to act in the best interest of the web instead of the best interest of their employers' profits... I've been avoiding getting into the precise details of the proposals out there to fix the tracking problem because things are changing so quickly across so many different tracks... Until then, know that there are two important things to know. First: there are new browser technologies and limits coming that could radically change how ads work and could make it easier for you to protect your privacy no matter what browser you use. Since this is the web, it'll take time, but everybody seems committed. Second: the way many of us think about a Browser War is in terms of marketshare -- and that is the wrong metric this time. There is a browser war, but it won't be won or lost based on who can convince the most people to switch to their browser. Because most people can't or won't switch on the platform that matters: mobile. In 2020, the desktop is a minor skirmish compared to browsers on phones. On phones, many people aren't really free to choose their browser. That's literally true on the iPhone, which Apple locks down so apps can only use its web rendering technology. And it's for-intents-and-purposes true on Android, where the vast majority of browsers just use Chromium. Yes, there is an Android browser ballot happening in Europe, but it's much too early to know what its effects will be.... The new Browser Wars aren't about who makes the fastest or best browser, they're about whose services you want and whose data policies you trust.

Opera Accused of Offering Predatory Loans Through Android apps
by Peter Reutemann 21 Jan '20

21 Jan '20

'"It's no secret that Opera isn't doing so well in the era of Chrome dominance," reports Android Police. "According to a report published by Hindenburg Research, the company's losses in browser revenue have apparently led it to create multiple loan apps with short payment windows and interest rates of ~365-876%, which are in violation of new Play Store rules Google enacted last year." The apps are aimed at India, Kenya and Nigeria, reports Engadget: The apps would claim to offer maximum annual percentage rate (APR) of 33 percent or less, but the actual rates were much higher, climbing to 438 percent in the case of OPesa. And while they publicly offered reasonable loan terms of 91 to 365 days, the real length was no more than 29 days (for OKash) and more often 15 days -- well under Google's 60-day minimum. The conditions only got worse for borrowers who missed their payments. Falling short by just a day could raise the APR as high as 876 percent. Also, the apps reportedly scraped phone contacts to harass family, friends and others with calls and texts in hopes this would pressure customers into paying up. These same notices often threatened legal action. Android Police points out that Opera became a public company in mid-2017, shortly after it was purchased by a China-based investor group. But since then, "Opera's market share has continued to fall, due to the increasing dominance of Chrome.' -- source: https://slashdot.org/story/20/01/20/0329242 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Researchers find serious flaws in WordPress plugins used on 400k sites
by Peter Reutemann 20 Jan '20

20 Jan '20

'Serious vulnerabilities have recently come to light in three WordPress plugins that have been installed on a combined 400,000 websites, researchers said. InfiniteWP, WP Time Capsule, and WP Database Reset are all affected. The highest-impact flaw is an authentication bypass vulnerability in the InfiniteWP Client, a plugin installed on more than 300,000 websites. It allows administrators to manage multiple websites from a single server. The flaw lets anyone log in to an administrative account with no credentials at all. From there, attackers can delete contents, add new accounts, and carry out a wide range of other malicious tasks.' -- source: https://arstechnica.com/information-technology/2020/01/researchers-find-ser… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Another Project Goes Private: Amara Stops Being Developed As Open Source
by Peter Reutemann 20 Jan '20

20 Jan '20

'Slashdot reader northar writes: Subtitling project Amara closes its repository as focus is shifting... Amara was AGPL up until going private. While future improvements to the code base from the Participatory Culture Foundation (PCF) will not be public, a copy of the last public code base has been preserved at Gitlab, should anyone be interested in the work done up until now. Note that no support is given from PCF for this code >From Amara's official statement on the move: The Participatory Culture Foundation began as a nonprofit in 2006 with a focus on creating open source software to ensure that emerging video technologies were accessible to all.... For an organization like PCF, which relies on revenue generated from sustainability initiatives to fund social impact work, we believe the risk to these initiatives outweighs the potential or perceived public benefit from maintaining open code. Releasing software as open source unfortunately does not provide protection against well-funded technology firms that are driven by profit... Without the proper market position and resources, a smaller organization that relies on revenue from software they build can be outmaneuvered or overpowered with the very technology they created (assuming their code is open source). This is not only a threat to smaller organizations, but has also become a bigger debate that much larger companies are also hashing out. For venture-funded or publicly traded firms, the open source approach can be a calculated risk that makes business sense. But for less-capitalized organizations or nonprofits, like PCF, who lack significant market power, making software open source puts other more well-resourced players in position to leverage the technology in ways that may undermine the sustainability and/or the values of the original developer. With these shifts in the computing landscape, PCF has not seen individuals or communities as the primary beneficiary of releasing Amara code as open source. Instead, we have unfortunately had firsthand experience with a venture-funded organization deploying code we created and using it in ways that we did not think aligned well with our values.... As we undertake this shift in 2020, we are aware that the computing landscape will continue to change and thus we remain open to newer and better strategies for making source code available in the long-term. Future strategies might include data trusts and/or new licenses that better align with our sustainability initiatives and mission.' -- source: https://news.slashdot.org/story/20/01/18/1753246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Are Software Designers Ignoring The Needs of the Elderly?
by Peter Reutemann 20 Jan '20

20 Jan '20

'"[A]t the very time that it's become increasingly difficult for anyone to conduct their day to day lives without using the Net, some categories of people are increasingly being treated badly by many software designers," argues long-time Slashdot reader Lauren Weinstein: The victims of these attitudes include various special needs groups — visually and/or motor impaired are just two examples — but the elderly are a particular target. Working routinely with extremely elderly persons who are very active Internet users (including in their upper 90s!), I'm particularly sensitive to the difficulties that they face keeping their Net lifelines going. Often they're working on very old computers, without the resources (financial or human) to permit them to upgrade. They may still be running very old, admittedly risky OS versions and old browsers — Windows 7 is going to be used by many for years to come, despite hitting its official "end of life" for updates a few days ago. Yet these elderly users are increasingly dependent on the Net to pay bills (more and more firms are making alternatives increasingly difficult and in some cases expensive), to stay in touch with friends and loved ones, and for many of the other routine purposes for which all of us now routinely depend on these technologies.... There's an aspect of this that is even worse. It's attitudes! It's the attitudes of many software designers that suggest they apparently really don't care about this class of users much — or at all. They design interfaces that are difficult for these users to navigate. Or in extreme cases, they simply drop support for many of these users entirely, by eliminating functionality that permits their old systems and old browsers to function. He cites the example of Discourse, the open source internet forum software, which recently announced they'd stop supporting Internet Explorer. Weinstein himself hates Microsoft's browser, "Yet what of the users who don't understand how to upgrade? Who don't have anyone to help them upgrade? Are we to tell them that they matter not at all?" So he confronted Stack Exchange co-founder Jeff Atwood (who is also one of the co-founders of Discourse) on Twitter — and eventually found himself blocked. "Far more important though than this particular case is the attitude being expressed by so many in the software community, an attitude that suggests that many highly capable software engineers don't really appreciate these users and the kinds of problems that many of these users may have, that can prevent them from making even relatively simple changes or upgrades to their systems — which they need to keep using as much as anyone — in the real world."' -- source: https://developers.slashdot.org/story/20/01/19/0255220 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Telnet Passwords Leaked For More Than 500,000 Servers, Routers, and IoT Devices
by Peter Reutemann 20 Jan '20

20 Jan '20

'ZDNet is reporting on a security breach leaking "a massive list of Telnet credentials for more than 515,000 servers, home routers, and IoT (Internet of Things) 'smart' devices." The list, which was published on a popular hacking forum, includes each device's IP address, along with a username and password for the Telnet service, a remote access protocol that can be used to control devices over the internet... Some devices were located on the networks of known internet service providers (indicating they were either home router or IoT devices), but other devices were located on the networks of major cloud service providers... According to experts to who ZDNet spoke this week, and a statement from the leaker himself, the list was compiled by scanning the entire internet for devices that were exposing their Telnet port. The hacker then tried using (1) factory-set default usernames and passwords, or (2) custom, but easy-to-guess password combinations.... To our knowledge, this marks the biggest leak of Telnet passwords known to date. As ZDNet understands, the list was published online by the maintainer of a DDoS-for-hire (DDoS booter) service... When asked why he published such a massive list of "bots," the leaker said he upgraded his DDoS service from working on top of IoT botnets to a new model that relies on renting high-output servers from cloud service providers.' -- source: https://it.slashdot.org/story/20/01/19/1649234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Why Did Red Hat Drop Its Support for Docker's Runtime Engine?
by Peter Reutemann 19 Jan '20

19 Jan '20

'"I've grown quite fond of the docker container runtime. It's easy to install and use, and many of the technologies I write about depend upon this software," writes TechRepublic/Linux.com contributor Jack Wallen. "But Red Hat has other plans." The company decided -- seemingly out of the blue -- to drop support for the docker runtime engine. In place of docker came Podman. When trying to ascertain why Red Hat split with Docker, nothing came clear. Sure, I could easily draw the conclusion that Red Hat had grown tired of the security issues surrounding Docker and wanted to take matters in their own hands. There was also Red Hat's issue with "no big fat daemons." If that's the case, how do they justify their stance on systemd? Here's where my tinfoil hat comes into play. Understand this is pure conjecture here and I have zero facts to back these claims up... Red Hat is now owned by IBM. IBM was desperate to gain serious traction within the cloud. To do that, IBM needed Red Hat, so they purchased the company. Next, IBM had to score a bit of vendor lock-in. Using a tool like docker wouldn't give them that lock-in. However, if Red Hat developed and depended on their own container runtime, vendor lock-in was attainable.... Red Hat has jettisoned a mature, known commodity for a less-mature, relatively unknown piece of software -- without offering justification for the migration.... Until Red Hat offers up a sound justification for migrating from the docker container engine to Podman, there's going to be a lot of people sporting tinfoil hats. It comes with the territory of an always-connected world. And if it does turn out to be an IBM grab for vendor lock-in, there'll be a lot of admins migrating away from RHEL/CentOS to the likes of Ubuntu Server, SUSE/openSUSE, Debian, and more. Red Hat's product manager of containers later touted Podman's ability to deploy containers without root access privileges in an interview with eWeek. "We felt the sum total of its features, as well as the project's performance, security and stability, made it reasonable to move to 1.0. Since Podman is set to be the default container engine for the single-node use case in Red Hat Enterprise Linux 8, we wanted to make some pledges about its supportability." And a Red Hat spokesperson also shared their position with The New Stack. "We saw our customer base wanting the container runtime lifecycle baked-in to the OS or in delivered tandem with OpenShift."' -- source: https://linux.slashdot.org/story/20/01/18/0236253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Tuxedo's New Manjaro Linux Laptops Will Include Massive Customization

'Tuxedo Computers "has teamed up with Manjaro to tease not one, not two, but several" Linux laptops, Forbes reports: The Tuxedo Computers InfinityBook Pro 15...can be loaded with up to 64GB of RAM, a 10th-generation Intel Core i7 CPU, and as high as a 2TB Samsung EVO Plus NVMe drive. You can also purchase up to a 5-year warranty, and user-installed upgrades will not void the warranty... Manjaro Lead Project Developer Philip Müller also teased a forthcoming AMD Ryzen laptop [on Forbes' "Linux For Everyone" podcast]. "Yes, we are currently evaluating which models we want to use because the industry is screaming for that," Müller says. "In the upcoming weeks we might get some of those for internal testing. Once they're certified and the drivers are ready, we'll see when we can launch those." Müller also tells me they're prepping what he describes as a "Dell XPS 13 killer." "It's 10th-generation Intel based, we will have it in 14-inch with a 180-degree lid, so you can lay it flat on your desk if you like," he says. The Manjaro/Tuxedo Computers partnership will also offer some intense customization options, Forbes adds. "Want your company logo laser-etched on the lid? OK. Want to swap out the Manjaro logo with your logo on the Super key? Sure, no problem. Want to show off your knowledge of fictional alien races?

“Windows Refund Day” Retrospective
by Lawrence D'Oliveiro 18 Jan '20

18 Jan '20

Just been watching this video <https://www.youtube.com/watch?v=1j9j-Ywjmbk> about that day in 1999 when open-source fans in a number of countries (including NZ) staged a march to demand a refund for the copies of Microsoft Windows that were bundled with hardware that they bought, even though they didn’t want that OS. It also recounts the story of the first person to actually get such a refund, and the rigmarole she had to go through to get it. Nowadays, I expect such a demand would be even less effective than it was then. The price of Windows to the hardware manufacturers is heavily offset (likely by more than 100%) by payments they get for preinstalling “crapware” (demo, time-limited and “lite” versions of various apps) from software vendors. So if they have to refund you the one, they will also deduct the other, and you end up with a net pittance, or very likely nothing at all, for saying no to Windows.

Do Parents Think Free Software Is Malware?
by Lawrence D'Oliveiro 18 Jan '20

18 Jan '20

Came across this article <https://opensource.com/life/15/12/dear-parents-let-your-kids-use-open-sourc…> from a few years ago, relating the tale of a teenager who was given an expensive laptop, who chose to replace its Windows OS (and included software) with Ubuntu. His parents were livid when they found out--two years after the fact. They jumped to the conclusion that his machine was now under the control of malware and hackers and all the rest of it, not to mention his throwing away the software they had paid good money for. So he resorted to Reddit (!) to get advice on how to explain things to his parents. The thread <https://www.reddit.com/r/linux/comments/3rfukp/i_really_need_advice/> has, in perhaps typical Reddit fashion, a mix of useful and not-so-useful responses. Though the upshot was, he was able to come to an accommodation with his parents, even if it did involve paying back the cost of the firewall/antivirus subscription that he didn’t use. That teen is an adult now. I wonder if it was an isolated case...

Bruce Schneier on 5G Security
by Peter Reutemann 17 Jan '20

17 Jan '20

'Bruce Schneier comments on the issues surrounding 5G security: [...] Keeping untrusted companies like Huawei out of Western infrastructure isn't enough to secure 5G. Neither is banning Chinese microchips, software, or programmers. Security vulnerabilities in the standards, the protocols and software for 5G, ensure that vulnerabilities will remain, regardless of who provides the hardware and software. These insecurities are a result of market forces that prioritize costs over security and of governments, including the United States, that want to preserve the option of surveillance in 5G networks. If the United States is serious about tackling the national security threats related to an insecure 5G network, it needs to rethink the extent to which it values corporate profits and government espionage over security. To be sure, there are significant security improvements in 5G over 4G in encryption, authentication, integrity protection, privacy, and network availability. But the enhancements aren't enough. The 5G security problems are threefold. First, the standards are simply too complex to implement securely. This is true for all software, but the 5G protocols offer particular difficulties. Because of how it is designed, the system blurs the wireless portion of the network connecting phones with base stations and the core portion that routes data around the world. Additionally, much of the network is virtualized, meaning that it will rely on software running on dynamically configurable hardware. This design dramatically increases the points vulnerable to attack, as does the expected massive increase in both things connected to the network and the data flying about it. Second, there's so much backward compatibility built into the 5G network that older vulnerabilities remain. 5G is an evolution of the decade-old 4G network, and most networks will mix generations. Without the ability to do a clean break from 4G to 5G, it will simply be impossible to improve security in some areas. Attackers may be able to force 5G systems to use more vulnerable 4G protocols, for example, and 5G networks will inherit many existing problems. Third, the 5G standards committees missed many opportunities to improve security. Many of the new security features in 5G are optional, and network operators can choose not to implement them. The same happened with 4G; operators even ignored security features defined as mandatory in the standard because implementing them was expensive. But even worse, for 5G, development, performance, cost, and time to market were all prioritized over security, which was treated as an afterthought.' -- source: https://mobile.slashdot.org/story/20/01/16/1514231 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Browser Benchmark Battle: Chrome Vs. Firefox Vs. Edge Vs. Brave
by Peter Reutemann 17 Jan '20

17 Jan '20

'It's been some 18 months since VentureBeat's last browser benchmark battle. What better time to get the latest results than the start of a new year? Over the past year and a half, Google Chrome has continued to dominate market share, Mozilla Firefox has doubled down on privacy, Microsoft Edge has embraced Chromium, and Brave launched out of beta. You can click on the individual test to see the results: SunSpider: Edge wins! Octane: Chrome wins! Kraken: Firefox wins! JetStream: Edge wins! MotionMark: Edge wins! Speedometer: Edge wins! Basemark: Brave wins! WebXPRT: Firefox wins! The Chromium version of Edge did a lot better given that the stable release only arrived this week. We were expecting improvements, but not so many outright wins. That said, browser performance was solid across all four contestants -- each browser won at least one test. Performance of course shouldn't be your only consideration when picking your preferred app for consuming internet content. As long as you're using a browser that receives regular updates (and all four of these meet that criteria), you can expect performance to be solid. There is certainly room for improvement, but Chrome, Firefox, and now Edge, as well as Brave, are all quite capable.' -- source: https://news.slashdot.org/story/20/01/16/180227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The PinePhone starts shipping—a Linux-powered smartphone for $150
by Peter Reutemann 17 Jan '20

17 Jan '20

'Pine64 has announced that it is finally shipping the PinePhone, a smartphone that takes the rare step outside the Android/iOS duopoly and is designed to run mainline Linux distributions. The PinePhone starts shipping January 17 in the "Braveheart" developer edition. This initial "Braveheart" batch of devices is meant for "developer and early adopter" users, according to the Pine64 Store. The phone doesn't come with an end-user OS pre-installed and, instead, only comes with a factory test image that allows for easy verification that the hardware works. Users are expected to flash their own OS to the device. There are several available, from Ubuntu Touch to Sailfish OS, but they are all currently in an unfinished alpha state. Pine64 says that only enthusiasts with "extensive Linux experience" are the intended customer here—this isn't (yet?) a mainstream product. It's hard to mention PinePhone without mentioning that other Linux smartphone, the Purism Librem 5. They could both end up running the same software one day, but the two companies are taking totally different approaches to hardware. Purism has a hardline requirement for the hardware: it needs to be as open and freedom-focused as possible, which means the company couldn't use the typical supply chain that exists for Android phones. Purism has only a limited amount of open source-compatible vendors to choose from, and it uses M.2 socketed chips for the closed-source Wi-Fi/Bluetooth and Cell modem. The result is a device that is very thick (16mm), hot, and expensive, at $750. The PinePhone is less averse to binary blobs and is a lot closer to a normal smartphone. It's a more reasonable thickness (9mm) and a more reasonable price: $150.' -- source: https://arstechnica.com/gadgets/2020/01/the-pinephone-starts-shipping-a-lin… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Lays Off 70 As It Waits For New Products To Generate Revenue
by Peter Reutemann 16 Jan '20

'According to TechCrunch, Mozilla has laid off about 70 employees today. From the report: In an internal memo, Mozilla chairwoman and interim CEO Mitchell Baker specifically mentions the slow rollout of the organization's new revenue-generating products as the reason for why it needed to take this decision. The overall number may still be higher, though, as Mozilla is still looking into how this decision will affect workers in the UK and France. In 2018, Mozilla Corporation (as opposed to the much smaller Mozilla Foundation) said it had about 1,000 employees worldwide. Baker says laid-off employees will receive "generous exit packages" and outplacement support. She also notes that the leadership team looked into shutting down the Mozilla innovation fund but decided that it needed it in order to continue developing new products. In total, Mozilla is dedicating $43 million to building new products. "You may recall that we expected to be earning revenue in 2019 and 2020 from new subscription products as well as higher revenue from sources outside of search. This did not happen," Baker writes in her memo. "Our 2019 plan underestimated how long it would take to build and ship new, revenue-generating products. Given that, and all we learned in 2019 about the pace of innovation, we decided to take a more conservative approach to projecting our revenue for 2020. We also agreed to a principle of living within our means, of not spending more than we earn for the foreseeable future." "As we look to the future, we know we must take bold steps to evolve and ensure the strength and longevity of our mission," Baker adds. "Mozilla has a strong line of sight to future revenue generation, but we are taking a more conservative approach to our finances. This will enable us to pivot as needed to respond to market threats to internet health, and champion user privacy and agency."' -- source: https://news.slashdot.org/story/20/01/15/2048210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Launches Chromium Edge for Windows 7, Windows 8, Windows 10, and macOS
by Peter Reutemann 16 Jan '20

16 Jan '20

'Microsoft today launched its new Edge browser based on Google's Chromium open source project. You can download Chromium Edge now for Windows 7, Windows 8, Windows 10, and macOS directly from microsoft.com/edge in more than 90 languages. From a report: Business features aside, there's also support for Chrome-based extensions, 4K streaming, Dolby audio, inking in PDF, and privacy tools. For the last one, it's worth noting that tracking prevention is on by default and offers three levels of control, like Firefox's tracking protection. Chrome extension support is probably the most important feature for most users. By default, extensions that have been ported over to Edge can be downloaded from the Microsoft Store. Chromium Edge also has an option to "Allow extensions from other stores" to get Chrome extensions from the Chrome Web Store. There are still a few features missing from Chromium Edge, most notably history sync and extension sync. Microsoft is working on these and some other inking functionality that it still wants to port from legacy Edge, as Microsoft is calling it. Microsoft also claims that Chromium Edge is "twice as fast as legacy Edge." Curiously, the team isn't making any claims against other browsers -- at least not yet.' -- source: https://tech.slashdot.org/story/20/01/15/187215 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

More Than Half a Billion Android Users Have Installed 'Fleeceware' Apps
by Peter Reutemann 16 Jan '20

16 Jan '20

'Security researchers from Sophos say they've discovered a new set of "fleeceware" apps that appear to have been downloaded and installed by more than 600 million Android users. From a report: The term fleeceware is a recent addition to the cyber-security jargon. It was coined by UK cyber-security firm Sophos last September following an investigation that discovered a new type of financial fraud on the official Google Play Store. It refers to apps that abuse the ability for Android apps to run trial periods before a payment is charged to the user's account. By default, all users who sign up for an Android app trial period, have to cancel the trial period manually to avoid being charged. However, most users just uninstall an app when they don't like it. The vast majority of app developers interpret this action -- a user uninstalling their app -- as a trial period cancelation and don't follow through with a charge. But last year, Sophos discovered that some Android app developers didn't cancel an app's trial period once the app is uninstalled and they don't receive a specific request from the user. Sophos said it initially discovered 24 Android apps that were charging obscene fees (between $100 and $240 per year) for the most basic and simplistic apps, such as QR/barcode readers and calculators.' -- source: https://news.slashdot.org/story/20/01/15/1721256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linus Torvalds Versus ZFS
by Lawrence D'Oliveiro 14 Jan '20

14 Jan '20

Came across this article <https://arstechnica.com/gadgets/2020/01/linus-torvalds-zfs-statements-arent…> reporting that Linus Torvalds recommends against using Sun/Oracle’s ZFS with Linux. The licensing issue (on top of Oracle’s infamous litigiousness) is a real concern, but the author also has a problem with Torvalds’ claims over filesystem performance and whether the code base is still being maintained or not. Out of curiosity, I went to read the original discussion thread. Not far along, I came across this <https://www.realworldtech.com/forum/?threadid=189711&curpostid=189959> later clarification by Torvalds: > Please, Linus, stop being arrogant and ignorant, read this > release note and tell us why you think ZFS is more of a buzzword > and has no real maintenance. I'm talking about small details like the fact that Oracle owns the copyrights, but turned things closed-source, so the "other" ZFS project is a fork of an old code base. If you are talking about ZFS, you're talking about the Oracle version. Do you think it has a lot of development going on? I don't know. And if you're talking about OpenZFS, then yes, there's clearly maintenance there, but it has all the questions about what happens if Oracle ever decides - again - that "copyright" means something different than anybody else thinks it means. Also the Ars Technica author seemed to feel that the kernel developers closed off certain kernel symbols to non-GPL code out of “spite”, to which Torvalds replies: > Not going out of your way to support ZFS is one thing. That we > completely perfectly understand. Going out of your way to > deliberately break ZFS is another thing. The kernel developers > are being assholes for doing that! We didn't go out of our way to deliberately break anything. But we do occasionally turn symbols that aren't meant to be used outside the kernel into GPL-only, because they have some internal implementation issues. The fact is, the whole point of the GPL is that you're being "paid" in terms of tit-for-tat: we give source code to you for free, but we want source code improvements back. If you don't do that but instead say "I think this is _legal_, but I'm not going to help you" you certainly don't get any help from us. So things that are outside the kernel tree simply do not matter to us. They get absolutely zero attention. We simply don't care. It's that simple. And things that don't do that "give back" have no business talking about us being assholes when we don't care about them.

Unpatched Citrix Vulnerability Now Exploited, Patch Weeks Away
by Peter Reutemann 14 Jan '20

14 Jan '20

'On December 16, 2019, Citrix revealed a vulnerability in the company's Application Delivery Controller and Gateway products -- commercial virtual-private-network gateways formerly marketed as NetScaler and used by tens of thousands of companies. The flaw, discovered by Mikhail Klyuchnikov of Positive Technologies, could give an attacker direct access to the local networks behind the gateways from the Internet without the need for an account or authentication using a crafted Web request. Citrix has published steps to reduce the risk of the exploit. But these steps, which simply configure a responder to handle requests using the text that targets the flaw, breaks under some circumstances and might interfere with access to the administration portal for the gateways by legitimate users. A permanent patch will not be released until January 20. And as of January 12, over 25,000 servers remain vulnerable, based on scans by Bad Packets. This is not surprising, considering the number of Pulse Secure VPNs that have not yet been patched over six months after a fix was made available, despite Pulse Secure executives saying that they have "worked aggressively" to get customers to patch that vulnerability. And given that vulnerable Pulse Secure servers have been targeted now for ransomware attacks, the same will likely be true for unprotected Citrix VPN servers -- especially since last week, proof-of-concept exploits of the vulnerability began to appear, including at least two published on GitHub, as ZDNet's Catalin Cimpanu reported. "The vulnerability allows the remote execution of commands in just two HTTP requests, thanks to a directory traversal bug in the implementation of the gateway's Web interface," the report adds. "The attacks use a request for the directory '/vpn/../vpns/' to fool the Apache Web server on the gateway to point to the '/vpns/' directory without authentication. The attacks then inject a command based on the template returned from the first request." You can check for the vulnerability here.

ICANN Wants to Let VeriSign Raise Prices on .Com Domains
by Peter Reutemann 14 Jan '20

14 Jan '20

'VeriSign has released a "proposed agreement" with ICANN to amend their exclusive .com registry agreement to allow them to raise the price of dotcom registrations up to 28% every six years. Those new terms "are now open to public comment" -- and the Register points out that ICANN's decision seems to come with a corresponding $20 million for ICANN: Operator of the dot-com registry, Verisign, has decided to pay DNS overseer ICANN $4 million a year for the next five years in order to "educate the wider ICANN community about security threats." Even though the generous $20 million donation has nothing to do with ICANN signing off on an extension of the dot-com contract until 2024, the "binding letter of intent" [PDF] stating the exact amount of funding will be appended to the registry agreement that Verisign has with ICANN to run the dot-com registry. That extension lifts a price freeze put in place several years ago and will allow Verisign to increase prices by seven per cent a year [in each of the last four years of each six year contract renewal]. It's an increase that we calculated was worth $993 million and which the stock market appeared to agree with when it raised the company's share price by 16 per cent when the agreement was first flagged in November 2018... ICANN explains the $20 million this time will be used to "support ICANN's initiatives to preserve and enhance the security, stability and resiliency of the DNS, including root server system governance, mitigation of DNS security threats, promotion and/or facilitation of DNSSEC deployment, the mitigation of name collisions, and research into the operation of the DNS." Which is all entirely above board and not at all shady.' -- source: https://tech.slashdot.org/story/20/01/13/0512230 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

This Year's Y2K20 Bug Came Directly From 'A Lazy Fix' to the Y2K Bug
by Peter Reutemann 13 Jan '20

13 Jan '20

'Slashdot reader The8re still remembers the Y2K bug. Now he shares a New Scientist article explaining how it led directly to this year's Y2020 bug -- which affected more than just parking meters: WWE 2K20, a professional wrestling video game, also stopped working at midnight on 1 January 2020. Within 24 hours, the game's developers, 2K, issued a downloadable fix. Another piece of software, Splunk, which ironically looks for errors in computer systems, was found to be vulnerable to the Y2020 bug in November. The company rolled out a fix to users the same week -- which include 92 of the Fortune 100, the top 100 companies in the US.... The Y2020 bug, which has taken many payment and computer systems offline, is a long-lingering side effect of attempts to fix the Y2K, or millennium bug. Both stem from the way computers store dates. Many older systems express years using two numbers -- 98, for instance, for 1998 -- in an effort to save memory. The Y2K bug was a fear that computers would treat 00 as 1900, rather than 2000. Programmers wanting to avoid the Y2K bug had two broad options: entirely rewrite their code, or adopt a quick fix called "windowing", which would treat all dates from 00 to 20, as from the 2000s, rather than the 1900s. An estimated 80 percent of computers fixed in 1999 used the quicker, cheaper option. "Windowing, even during Y2K, was the worst of all possible solutions because it kicked the problem down the road," says Dylan Mulvin at the London School of Economics.... Another date storage problem also faces us in the year 2038. The issue again stems from Unix's epoch time: the data is stored as a 32-bit integer, which will run out of capacity at 3.14 am on 19 January 2038.' -- source: https://it.slashdot.org/story/20/01/12/0221226 Laziness always bites you in the bum in the end...

'Why I Finally Switched from Chrome to Firefox - and You Should Too'
by Peter Reutemann 13 Jan '20

13 Jan '20

'In 2018 an associate technology editor at Fast Company's Co.Design wrote an article titled "Why I'm switching from Chrome to Firefox and you should too." Today shanen shared a similar article from Digital Trends. Their writer announces that after years of experimenting with both browsers, they've also finally switched from Chrome to Mozilla Firefox -- "and you should too." The biggest draw for me was, of course, the fact that Mozilla Firefox can finally go toe-to-toe with Google Chrome on the performance front, and often manages to edge it out as well... Today, in addition to being fast, Firefox is resource-efficient, unlike most of its peers. I don't have to think twice before firing up yet another tab. It's rare that I'm forced to close an existing tab to make room for a new one. On Firefox, my 2015 MacBook Pro's fans don't blast past my noise-canceling headphones, which happened fairly regularly on Chrome as it pushed my laptop's fans to their helicopter-like limits to keep things running. This rare balance of efficiency and performance is the result of the countless under-the-hood upgrades Firefox has rolled out in the last couple of years... Its Enhanced Tracking Protection framework keeps your identity safe by blocking trackers and cookies that otherwise follow you around the internet and collect sensitive information you probably didn't even know you were giving up. On top of that, Firefox can warn if a website is covertly mining cryptocurrency in the background. Most of these protections kick in by default and you have an exhaustive set of options to customize them the way you want. Firefox also lets you look into just how invasive a website is. It actively updates your personal privacy report so you can check how many trackers it has shut overall and for a specific website... What really clinched the switch to Mozilla Firefox was the fact that it's the only cross-platform browser that's not running Google's open-source Chromium platform. Microsoft's Edge, Brave, Opera, Vivaldi -- each of these browsers run on Chromium, accelerating Google's dominance over the web even when you're not directly using a Chrome user. Firefox, on the other hand, is powered by Mozilla's in-house Gecko engine that's not dependent on Chromium in any way. It may not seem like as vital of a trait as I make it sound, but it truly is, even though Chromium is open-source. Google oversees a huge chunk of the web, including ads, browser, and search, and this supremacy has allowed the company to pretty much run a monopoly and set its own rules for the open internet... Mozilla as a company has, despite a rocky journey, often taken bold stances in complex situations. In the Cambridge Analytica aftermath, Mozilla announced it would no longer run Facebook advertisements, cutting off direct marketing to over 2 billion users. In a world of tech companies taking frail, facile shots at protecting user privacy and barely delivering on their commitments, Mozilla is a breath of fresh air and you no longer have to live with any compromises to support it.' -- source: https://news.slashdot.org/story/20/01/11/2246247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linus Torvalds: Avoid Oracle's ZFS Kernel Code Until 'Litigious' Larry Signs Off
by Peter Reutemann 12 Jan '20

12 Jan '20

'"Linux kernel head Linus Torvalds has warned engineers against adding a module for the ZFS filesystem that was designed by Sun Microsystems -- and now owned by Oracle -- due to licensing issues," reports ZDNet: As reported by Phoronix, Torvalds has warned kernel developers against using ZFS on Linux, an implementation of OpenZFS, and refuses to merge any ZFS code until Oracle changes the open-source license it uses. ZFS has long been licensed under Sun's Common Development and Distribution License as opposed to the Linux kernel, which is licensed under GNU General Public License (GPL). Torvalds aired his opinion on the matter in response to a developer who argued that a recent kernel change "broke an important third-party module: ZFS". The Linux kernel creator says he refuses to merge the ZFS module into the kernel because he can't risk a lawsuit from "litigious" Oracle -- which is still trying to sue Google for copyright violations over its use of Java APIs in Android -- and Torvalds won't do so until Oracle founder Larry Ellison signs off on its use in the Linux kernel. "If somebody adds a kernel module like ZFS, they are on their own. I can't maintain it and I cannot be bound by other people's kernel changes," explained Torvalds. "And honestly, there is no way I can merge any of the ZFS efforts until I get an official letter from Oracle that is signed by their main legal counsel or preferably by Larry Ellison himself that says that yes, it's OK to do so and treat the end result as GPL'd," Torvalds continued. "Other people think it can be OK to merge ZFS code into the kernel and that the module interface makes it OK, and that's their decision. But considering Oracle's litigious nature, and the questions over licensing, there's no way I can feel safe in ever doing so."' -- source: https://linux.slashdot.org/story/20/01/11/0421238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hundreds of Millions of Cable Modems Are Vulnerable To New Cable Haunt Vulnerability
by Peter Reutemann 11 Jan '20

11 Jan '20

'A team of four Danish security researchers has disclosed this week a security flaw that impacts cable modems that use Broadcom chips. From a report: The vulnerability, codenamed Cable Haunt, is believed to impact an estimated 200 million cable modems in Europe alone, the research team said today. The vulnerability impacts a standard component of Broadcom chips called a spectrum analyzer. This is a hardware and software component that protects the cable modem from signal surges and disturbances coming via the coax cable. The component is often used by internet service providers (ISPs) in debugging connection quality. On most cable modems, access to this component is limited for connections from the internal network. The research team says the Broadcom chip spectrum analyzer lacks protection against DNS rebinding attacks, uses default credentials, and also contains a programming error in its firmware.' -- source: https://it.slashdot.org/story/20/01/10/1914204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox gets patch for critical 0-day that’s being actively exploited
by Peter Reutemann 10 Jan '20

10 Jan '20

'Mozilla has released a new version of Firefox that fixes an actively exploited zero-day that could allow attackers to take control of users' computers. In an advisory, Mozilla rated the vulnerability critical and said it was "aware of targeted attacks in the wild abusing this flaw." The US Cybersecurity and Infrastructure Security Agency said one or more exploits were "detected in the wild" and warned that attacks could be exploited to "take control of an affected system." The Mozilla advisory credited researchers at China-based Qihoo 360 with reporting the flaw. No other details about the attacks were immediately available. Neither Mozilla nor Qihoo 360 responded to emails asking for more information. CVE-2019-17026, as the vulnerability is indexed, is a type confusion, a potentially critical error that can result in data being written to, or read from, memory locations that are normally off-limits. These out-of-bounds reads may allow attackers to discover memory locations where malicious code is stored so that protections such as address space layout randomization can be bypassed. Out-of-bounds reads can also cause crashes. The flaw is fixed in Tuesday's release of Firefox 72.0.1. The patch came a day after version 72 fixed 11 other vulnerabilities, six of which were rated high. Three of those six bugs might make it possible for attackers to run malicious code on affected computers.' -- source: https://arstechnica.com/information-technology/2020/01/firefox-gets-patch-f… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Huawei Unveils OpenEuler, CentOS-Based Linux Distribution
by Peter Reutemann 10 Jan '20

10 Jan '20

'Huawei has released the source code of openEuler, its distribution of Linux based on CentOS. The operating system was formally launched by Huawei in September 2019 in response to U.S. sanctions, which had briefly affected the company's access to Windows and Android operating systems. The source code has now been published on Gitee, the Chinese version of Github. OpenEuler comprises two organizations on Gitee, one for source code and one for package sources. The openEuler organization was keen to highlight two particular packages, iSulad and A-Tune, among the openEuler source code. "iSulad is a lightweight gRPC service-based container runtime. Compared to runc, iSulad is written in C, but all interfaces are compatible with OCI. A-Tune is a system software to auto-optimize the system adaptively to multiple scenarios with embedded AI-engine." The announcement continues: "You will also see several infrastructure-supported projects that set up the community's operating systems... these systems are built on the Huawei Cloud through script automation." Among the package sources, covered by the src-openeuler organization on Gitee, are around 1,000 packages with versions in both ARM64 and X86 architecture packages. Huawei claims its developers have made a number of enhancements to ARM64 openEuler code to improve multi-core efficiency. It is also working on a "green computing" ecosystem with Linaro and the Green Industry Alliance. At the moment, the organization claims, there are more than 50 contributors and just under 600 commits. The openEuler community has around 20 SIGs or project groups.' -- source: https://tech.slashdot.org/story/20/01/09/058218 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Chrome To Hide Notification Spam Starting February 2020
by Peter Reutemann 09 Jan '20

09 Jan '20

'Following in Mozilla's footsteps, Google announced today plans to hide notification popup prompts inside Chrome starting next month, February 2020. ZDNet reports: According to a blog post published today, Google plans to roll out a "quieter notification permission UI that reduces the interruptiveness of notification permission requests." The change is scheduled for Google Chrome 80, scheduled for release on February 4, next month. Starting with Chrome 80 next month, Google's browser will also block most notification popups by default, and show an icon in the URL bar, similar to Firefox. When Chrome 80 launches next month, a new option will be added in the Chrome settings section that allows users to enroll in the new "quieter notification UI." Users can enable this option as soon as Chrome 80 is released, or they can wait for Google to enable it by default as the feature rolls out to the wider Chrome userbase in the following weeks. According to Google, the new feature works by hiding notification requests for Chrome users who regularly dismiss notification prompts. Furthermore, Chrome will also automatically block notification prompts on sites where users rarely accept notifications.

Half of the Websites Using WebAssembly Use it for Malicious Purposes
by Peter Reutemann 09 Jan '20

09 Jan '20

'Around half of the websites that use WebAssembly, a new web technology, use it for malicious purposes, according to academic research published last year. From a report: WebAssembly is a low-level bytecode language that was created after a joint collaboration between all major browser vendors. It introduces a new binary file format for transmitting code from a web server to a browser. Once it reaches the browser, WebAssembly code (Wasm) executes with near-native speed, similar to compiled C, C++, or Rust code. WebAssembly was created for both speed and performance. Due to its binary machine-friendly format, Wasm code is smaller than its equivalent JavaScript form, but also many times faster when executing. This has made WebAssembly the next incarnation of Adobe Flash, allowing websites to run complex CPU-intensive code without freezing a browser, a task for which JavaScript was never designed or optimized for.' -- source: https://it.slashdot.org/story/20/01/08/1421216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Here’s a new trend to watch out for: it’s being called “browser isolation” <https://www.theregister.co.uk/2020/01/07/cloudflare_buys_s2/>: S2 developed a ... headless version of Chromium – the open-source foundation of Chrome and about two dozen other browsers – that runs in the cloud and intercepts calls to the browser's Skia graphics layer. "Before it actually draws anything virtual, we intercept those Skia calls, we tokenize them, we compress them, we send them through to any HTML5 browser, where we redraw them locally, right on the machine," Remington explained. "We use WebAssembly. We push a little Skia library that runs local in your browser, any browser. ... Turns out, it's very secure, because that is not an attack vector. It's only draw commands." ... According to Harnett, S2's scheme results in a 60 per cent bandwidth savings. "People are surprised when we say that in many cases, it's faster than local" ...

PGP keys, software security, and much more threatened by new SHA1 exploit
by Peter Reutemann 08 Jan '20

08 Jan '20

'Three years ago, Ars declared the SHA1 cryptographic hash algorithm officially dead after researchers performed the world’s first known instance of a fatal exploit known as a "collision" on it. On Tuesday, the dead SHA1 horse got clobbered again as a different team of researchers unveiled a new attack that’s significantly more powerful. The new collision gives attackers more options and flexibility than were available with the previous technique. It makes it practical to create PGP encryption keys that, when digitally signed using SHA1 algorithm, impersonate a chosen target. More generally, it produces the same hash for two or more attacker-chosen inputs by appending data to each of them. The attack unveiled on Tuesday also costs as little as $45,000 to carry out. The attack disclosed in 2017, by contrast, didn’t allow forgeries on specific predetermined document prefixes and was evaluated to cost from $110,000 to $560,000 on Amazon’s Web Services platform, depending on how quickly adversaries wanted to carry it out. The new attack is significant. While SHA1 has been slowly phased out over the past five years, it remains far from being fully deprecated. It’s still the default hash function for certifying PGP keys in the legacy 1.4 version branch of GnuPG, the open-source successor to PGP application for encrypting email and files. Those SHA1-generated signatures were accepted by the modern GnuPG branch until recently, and were only rejected after the researchers behind the new collision privately reported their results. Git, the world's most widely used system for managing software development among multiple people, still relies on SHA1 to ensure data integrity. And many non-Web applications that rely on HTTPS encryption still accept SHA1 certificates. SHA1 is also still allowed for in-protocol signatures in the Transport Layer Security and Secure Shell protocols.' -- source: https://arstechnica.com/information-technology/2020/01/pgp-keys-software-se… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Chrome OS Has Stalled Out
by Peter Reutemann 07 Jan '20

07 Jan '20

'Speaking of Chromebooks, David Ruddock, opines at AndroidPolice: Chrome OS' problems really became apparent to me when Android app compatibility was introduced, around five years ago. Getting Android apps to run on Chrome OS was simultaneously one of the Chrome team's greatest achievements and one of its worst mistakes. In 2019, two things are more obvious than ever about the Android app situation on Chrome. The first is that the "build it and they will come" mantra never panned out. Developers never created an appreciable number of Android app experiences designed for Chrome (just as they never did for Android tablets). The second is that, quite frankly, Android apps are very bad on Chrome OS. Performance is highly variable, and interface bugs are basically unending because most of those apps were never designed for a point-and-click operating system. Sure, they crash less often than they did in the early days, but anyone saying that Android apps on Chrome OS are a good experience is delusional. Those apps are also a crutch that Chrome leans on to this day. Chrome OS doesn't have a robust photo editor? Don't worry, you can download an app! Chrome doesn't have native integration with cloud file services like Box, Dropbox, or OneDrive? Just download the app! Chrome doesn't have Microsoft Office? App! But this "solution" has basically become an insult to Chrome's users, forcing them to live inside a half-baked Android environment using apps that were almost exclusively designed for 6" touchscreens, and which exist in a containerized state that effectively firewalls them from much of the Chrome operating system. As a result, file handling is a nightmare, with only a very limited number of folders accessible to those applications, and the task of finding them from inside those apps a labyrinthine exercise no one should have to endure in 2019. This isn't a tenable state of affairs -- it's computing barbarism as far as I'm concerned. And yet, I've seen zero evidence that the Chrome team intends to fix it. It's just how it is. But Android apps, so far as I can tell, are basically the plan for Chrome. Certainly, Linux environment support is great for enthusiasts and developers, but there are very few commonly-used commercial applications available on Linux, with no sign that will change in the near future. It's another dead end. And if you want an even more depressing picture of Chrome's content ecosystem, just look at the pitiable situation with web apps.' -- source: https://developers.slashdot.org/story/20/01/06/1626227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

“Open Source” Journalism
by Lawrence D'Oliveiro 06 Jan '20

06 Jan '20

This week’s “Listening Post” on Al Jazeera (viewable here <https://www.aljazeera.com/programmes/listeningpost/2019/09/xinjiang-story-c…>) talks, in the latter part, about this new phenomenon of “open source” journalism. My understanding is, the meaning of “source” here is not that of “source code” familiar to software developers, but “source of information” as understood by journalists. That means getting information from public sources available to all. Even a tightly-controlled society like China makes a surprising amount of information freely available online--more than it really wants to make available, sometimes. And this information can be pieced together like a puzzle by perceptive investigators, to point to conclusions which can be directly at odds with public pronouncements from Government officials.

Linus Torvalds Calls Blogger's Linux Scheduler Tests 'Pure Garbage'
by Peter Reutemann 06 Jan '20

06 Jan '20

'On Wednesday Phoronix cited a blog post by C++ game developer Malte Skarupke claiming his spinlocks experiments had discovered the Linux kernel had a scheduler issue affecting developers bringing games to Linux for Google Stadia. Linus Torvalds has now responded: The whole post seems to be just wrong, and is measuring something completely different than what the author thinks and claims it is measuring. First off, spinlocks can only be used if you actually know you're not being scheduled while using them. But the blog post author seems to be implementing his own spinlocks in user space with no regard for whether the lock user might be scheduled or not. And the code used for the claimed "lock not held" timing is complete garbage. It basically reads the time before releasing the lock, and then it reads it after acquiring the lock again, and claims that the time difference is the time when no lock was held. Which is just inane and pointless and completely wrong... [T]he code in question is pure garbage. You can't do spinlocks like that. Or rather, you very much can do them like that, and when you do that you are measuring random latencies and getting nonsensical values, because what you are measuring is "I have a lot of busywork, where all the processes are CPU-bound, and I'm measuring random points of how long the scheduler kept the process in place". And then you write a blog-post blamings others, not understanding that it's your incorrect code that is garbage, and is giving random garbage values... You might even see issues like "when I run this as a foreground UI process, I get different numbers than when I run it in the background as a batch process". Cool interesting numbers, aren't they? No, they aren't cool and interesting at all, you've just created a particularly bad random number generator... [Y]ou should never ever think that you're clever enough to write your own locking routines.. Because the likelihood is that you aren't (and by that "you" I very much include myself -- we've tweaked all the in-kernel locking over decades, and gone through the simple test-and-set to ticket locks to cacheline-efficient queuing locks, and even people who know what they are doing tend to get it wrong several times). There's a reason why you can find decades of academic papers on locking. Really. It's hard. "It really means a lot to me that Linus responded," the blogger wrote later, "even if the response is negative." They replied to Torvalds' 1,500-word post on the same mailing list -- and this time received a 1900-word response arguing "you did locking fundamentally wrong..." The fact is, doing your own locking is hard. You need to really understand the issues, and you need to not over-simplify your model of the world to the point where it isn't actually describing reality any more... Dealing with reality is hard. It sometimes means that you need to make your mental model for how locking needs to work a lot more complicated...' -- source: https://linux.slashdot.org/story/20/01/06/012251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Open Source Initiative Co-Founder Bruce Perens Resigns, Citing Move Toward License 'That Isn't Freedom Respecting'
by Peter Reutemann 06 Jan '20

06 Jan '20

'Bruce Perens (Slashdot reader #3872) co-founded the Open Source Initiative with Eric Raymond in 1998. But on Thursday Perens posted "it seems to me that the organization is rather enthusiastically headed toward accepting a license that isn't freedom respecting. Fine, do it without me, please. "I asked Patrick to cancel my membership, and I would have unsubscribed from OSI lists, including this one, if your server was working..." The issue is a new software license drafted by lawyer Van Lindberg called the Cryptographic Autonomy License (or CAL). Another open-source-community leader familiar with the debate -- who spoke with The Register on condition of anonymity -- claimed Lindberg lobbied OSI directors privately to green-light the license, contrary to an approval process that's supposed to be carried out in public. "I don't think that's an appropriate characterization," said Lindberg, of law firm Dykema, in a phone interview with The Register. "I think there are number of people who from the beginning made up their minds about the Cryptographic Autonomy License. You'll see a lot of people jumping onto any pretext they can find in order to oppose it. With regard to this idea of lobbying, there have been procedural-type communications that I think are entirely reasonable," he added. "But all the substantive debate has been on the license review and license discussion forums...." Perens said he resigned because the OSI appears to have already decided to accept the license. He said he's headed in a different direction, which he called "coherent open source." "We've gone the wrong way with licensing," he said, citing the proliferation of software licenses. He believes just three are necessary, AGPLv3, the LGPLv3, and Apache v2. Meanwhile, the Cryptographic Autonomy License is envisioned for use with the distributed development platform Holo, notes the Register: According to Holo co-founder Arthur Brock, distributed peer-to-peer software needs a license that addresses cryptographic key rights, which is why the Cryptographic Autonomy License has been proposed. "We are trying to say: the only valid way to use our code is if that developer's end-users are the sole authors and controllers of their own private crypto keys," he wrote in a post last year. Lindberg said the Cryptographic Autonomy License is applicable to current web applications but it more meaningful in the context of distributed workloads and distributed computation, which he contends will become more important as people seek alternatives to the centralization of today's cloud-based systems. "A lot of people are very concerned about this concept of owning your data, owning your computer, having the ability to really control your computing experience and have it not be controlled by your cloud provider," said Lindberg. Perens said, "It's a good goal but it means you now need to have a lawyer to understand the license and to respond to your users." Slashdot asked Bruce Perens for details on "Coherent Open Source." Here's what he wrote back...' -- source: https://news.slashdot.org/story/20/01/05/208249 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Dell's Upcoming XPS 13 Linux Laptop Includes a Fingerprint Reader
by Peter Reutemann 06 Jan '20

06 Jan '20

'If you've been following the steady march of progress from Dell's Linux-first Project Sputnik team, you're no doubt aware that the "Developer Edition" variant of the XPS 13 is one of the finest Linux-ready ultrabooks you can buy. Just ahead of CES 2020, Dell is pushing out a few more improvements including a feature that's been hotly requested: fingerprint-reader support. It's one of several enhancements Dell is promising to Linux users for its 10th-generation XPS 13, including a new maximum of 32GB RAM and a redesigned "InfinityEdge" display that adds even more screen real estate, resulting in an adjusted 16:10 aspect ratio to match... Details on fingerprint-reader support are still a bit vague, but Dell says it will be released shortly after the system's February 2020 launch as an OTA (over-the-air) update, and then as part of the preloaded Ubuntu Developer Edition image it ships with the system. Dell's lead on Project Sputnik developer systems, Barton George, also blogged about Dell's new 86-inch 4K interactive touch monitor, as well as their upcoming Latitude 9510 notebook and 2-in-1 laptops, promising "a new ultra-premium class of products" offering 5G mobile broadband capabilities, AI-based productivity capabilities, and 30-plus hours of battery life. The blog post ends by noting that "While project Sputnik is the most visible Linux-based offerings from Dell, it is only a small fraction of the over 150 systems that make up Dell's Linux portfolio."' -- source: https://linux.slashdot.org/story/20/01/05/0137242 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Over its lifetime there's been 887,925 commits, and around 21,074 different authors: During 2019, the Linux kernel saw 74,754 commits, which is actually the lowest point since 2013. The 74k commits is compares to 80k commits seen in both 2017 and 2018, 77k commits in 2016, and 75k commits in both 2014 and 2015. Besides the commit count being lower, the author count for the year is also lower. 2019 saw around 4,189 different authors to the Linux kernel, which is lower than the 4,362 in 2018 and 4,402 in 2017. While the commit count is lower for the year, on a line count it's about average with 3,386,347 lines of new code added and 1,696,620 lines removed...

Employee error to blame for massive data leak, Wyze says

'Loads of folks found brand-new Wyze surveillance cameras under their trees or in their stockings this Christmas. And on Boxing Day, the company itself unwrapped a whole new world of trouble for everyone who uses its products, confirming a data leak that may have exposed personal data for millions of users over the course of a few weeks. Wyze first found out about the problem on the morning of December 26, company cofounder Dongsheng Song said in a corporate blog post. The company's investigation confirmed that user data was "not properly secured" and was exposed from December 4 onward. The database in question was basically a copy of the production database that Wyze created to work with, Song explained. Data points left exposed include user email addresses, camera nicknames, Wi-Fi network information, Wyze device information, some tokens associated with Alexa integrations, and "body metrics for a small number of product beta testers."' -- source: https://arstechnica.com/tech-policy/2019/12/surveillance-camera-company-wyz… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Vivaldi To Change User-Agent String To Chrome Due To Unfair Blocking
by Peter Reutemann 20 Dec '19

20 Dec '19

'Because some internet websites unfairly block browsers from accessing their services, starting with Vivaldi 2.10, released today, the Vivaldi browser plans to disguise itself as Chrome to allow users to access websites that unfairly block them. From a report: Vivaldi will do this by modifying its default user-agent (UA) string to the UA string used by Chrome. A UA string is a piece of text that browsers send to websites when they initiate a connection. The UA String contains data about the browser type, rendering engine, and operating system. For example, a UA string for Firefox on Windows looks like this: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:71.0) Gecko/20100101 Firefox/71.0. UA strings have been in use since the 90s. For decades, websites have used UA agent strings to fine-tune performance and features or block outdated browsers. However, many website owners these days use UA strings to block users from accessing their sites. Some do it because they're not willing to deal with browser-specific bugs, some do it because of pettiness, while big tech companies like Google and Microsoft have done it (and continue to do it) to sabotage competitors on the browser market.' -- source: https://tech.slashdot.org/story/19/12/19/2041250 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Nebula VPN routes between hosts privately, flexibly, and efficiently
by Peter Reutemann 20 Dec '19

20 Dec '19

'Last month, the engineering department at Slack—an instant messaging platform commonly used for community and small business organization—released a new distributed VPN mesh tool called Nebula. It's difficult to coherently explain Nebula in a nutshell. According to the people on Slack's engineering team, they asked themselves "what is the easiest way to securely connect tens of thousands of computers, hosted at multiple cloud service providers in dozens of locations around the globe?" And (developing) Nebula was the best answer they had. It's a portable, scalable overlay networking tool that runs on most major platforms, including Linux, MacOS, and Windows, with some mobile device support planned for the near future. Nebula-transmitted data is fully encrypted using the Noise protocol framework, which is also used in modern, highly security-focused projects such as Signal and WireGuard. Unlike more traditional VPN technologies—including WireGuard—Nebula automatically and dynamically discovers available routes between nodes and sends traffic down the most efficient path between any two nodes rather than forcing everything through a central distribution point.' -- source: https://arstechnica.com/gadgets/2019/12/nebula-vpn-routes-between-hosts-pri… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Facebook is Building an Operating System So it Can Ditch Android
by Peter Reutemann 20 Dec '19

20 Dec '19

'Facebook doesn't want its hardware like Oculus and Portal to be at the mercy of Google because they rely on its Android operating system. >From a report: That's why Facebook has tasked a co-author of Microsoft's Windows NT named Mark Lucovsky with building the social network an operating system from scratch, according the The Information's Alex Heath. "We really want to make sure the next generation has space for us," says Facebook's VP of hardware Andrew 'Boz' Bosworth. "We don't think we can trust the marketplace or competitors to ensure that's the case. And so we're gonna do it ourselves." By moving to its own OS, Facebook could have more freedom to bake social interaction -- and hopefully privacy -- deeper into its devices. It could also prevent a disagreement between Google and Facebook from derailing the roadmaps of Oculus, Portal, or future gadgets. One added bonus of moving to a Facebook-owned operating system? It could make it tougher to force Facebook to spin out some of its acquisitions, especially if Facebook goes with Instagram branding for its future augmented reality glasses.' -- source: https://tech.slashdot.org/story/19/12/19/1747243 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Apple, Google, and Amazon team up to create “CHIP,” a new smart home standard
by Peter Reutemann 19 Dec '19

'Apple, Google, Amazon, and the Zigbee Alliance have all teamed up to make a new smart home standard. The new working group went live today under the name of "Project Connected Home over IP" with announcement blog posts from Google, Apple, Zigbee, and a new website, connectedhomeip.com. The name doesn't sound too catchy until you realize "Connected Home over IP" abbreviates to "CHIP" which, across all these blog posts, is quietly used only a single time in the official FAQ. According to the new website, "The goal of the Connected Home over IP project is to simplify development for manufacturers and increase compatibility for consumers."

Hate Speech Row: Fine Or Jail Anyone Who Calls People Boffins, Geeks or Eggheads, Psychology Nerd Demands
by Lawrence D'Oliveiro 19 Dec '19

19 Dec '19

>From <https://www.theregister.co.uk/2019/12/18/nerds_hate_speech/>: Labeling super-smart people with terms like nerd, geek, or boffin is hate speech, and should be punishable as such, argues lecturer and Harley-Street psychotherapist Dr Sonja Falck. ... She then embarked on a “contextual analysis of literature” and decided that calling someone a boffin was equivalent to the worst racial slurs. A couple of points occur to me. One is, one should be careful of the logical pitfalls of arguing “A is no better than B”. Because the flip side of that is that you are also saying “B is no worse than A”. In the process of trying to demonize A, and in the absence of any additional evidence for your position, you could be seen to be trivializing B. The other point is that targeted groups seem to be granted a licence to own terms which are used as slurs against them. These terms become accepted as commonplace inside the group, that nobody outside is allowed to use.

Smart technologies are rapidly spreading among ordinary users. More and more intelligent and remotely controlled equipment appears in our lives. But let’s see not from the user’s side. Let’s mind like a creator’s. Where is it better to place a “control center”? More and more integrators are transferring their capacities to the public cloud; there is formed a system for management. Labels from all things come through the gateways and are processed directly in the cloud. If the Internet connection is interrupted, all modules continue to work, and immediately after the appearance of the connections are synchronized.

Open Source Gets No Respect, Episode #310

The developer of FUSE for macOS <https://www.theregister.co.uk/2019/12/16/fuse_macos_closed_source/> found that, while many companies were including his software in their commercial products, they were curiously reluctant to offer him any actual monetary support for his work. So he took the drastic step of making the latest version closed-source. While it continues to be available for non-commercial use at no charge, commercial vendors will need to license it for inclusion in their products. The result? He has actually got a bunch of licensing deals signed now.

Mozilla To Add Second DNS-over-HTTPS (DoH) Provider in Firefox
by Peter Reutemann 18 Dec '19

18 Dec '19

'Mozilla has announced that NextDNS would be joining Cloudflare as the second DNS-over-HTTPS (DoH) provider inside Firefox. From a report: The browser maker says NextDNS passed the conditions imposed by its Trusted Recursive Resolver (TRR) program, and can now be added as a second option for DoH inside Firefox. These conditions include (1) limiting the data NextDNS collects from the DoH server used by Firefox users; (2) being transparent about the data they collect; and (3) promising not to censor, filter, or block DNS traffic unless specifically requested by law enforcement. DNS-over-HTTPS, or DoH, is a new feature that was added to Firefox last year. When enabled, it encrypts DNS traffic coming in and out of the browser. DNS traffic is not only encrypted but also moved from port 53 (for DNS traffic) to port 443 (for HTTPS traffic), effectively hiding DNS queries and replies inside the browser's normal stream of HTTPS content. This encrypted DNS traffic reaches a so-called DoH resolver. Here, the DoH traffic is decrypted and the DoH resolver makes the DNS query on the user's behalf, receives the result, encrypts it, and sends it back to the user's browser -- also disguised inside encrypted HTTPS content.' -- source: https://tech.slashdot.org/story/19/12/17/1922254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Npm Team Warns of New 'Binary Planting' Bug
by Peter Reutemann 17 Dec '19

17 Dec '19

' The team behind npm, the biggest package manager for JavaScript libraries, issued a security alert yesterday, advising all users to update to the latest version (6.13.4) to prevent "binary planting" attacks. From a report: Npm (Node.js Package Manager) devs say the npm command-line interface (CLI) client is impacted by a security bug -- a combination between a file traversal and an arbitrary file (over)write issue. The bug can be exploited by attackers to plant malicious binaries or overwrite files on a user's computer. The vulnerability can be exploited only during the installation of a boobytrapped npm package via the npm CLI. "However, as we have seen in the past, this is not an insurmountable barrier," said the npm team, referring to past incidents where attackers planed backdoored or boobytrapped packages on the official npm repository. Npm devs say they've been scanning the npm portal for packages that may contain exploit code designed to exploit this bug, but have not seen any suspicious cases. "That does not guarantee that it hasn't been used, but it does mean that it isn't currently being used in published packages on the [official npm] registry," npm devs said.' -- source: https://it.slashdot.org/story/19/12/16/1513245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Halts Chrome 79 Rollout After It Breaks Some Android Apps
by Peter Reutemann 16 Dec '19

16 Dec '19

'Chrome 79 is creating an issue with WebView (the Android component that allows apps to display content from the web), reports 9to5Google: On Friday morning, Android developers reliant on WebView and local storage began encountering an issue where their apps lost data after users updated to version 79 of WebView. Those affected took to Chromium's bug tracker, and have described the incident as a "catastrophe" and "major issue." To end users, it's as if apps were entirely reset and just downloaded for the first time. This includes saved data disappearing or being logged out. Given the level of system opacity, most will blame developers for a problem that's out of their hands. By that afternoon, Google engineers responded and isolated the issue to "profile layout changes" where "local storage was missed off the list of files migrated." A member of the Chromium team apologized Saturday morning, with the Chrome/WebView rollout halted after 50% of devices already received the update. At the highest priority level (P0), Google is currently "working on a solution that minimizes the data loss, and that can be rolled out safely." The last guidance for a patch is 5-7 days.' -- source: https://tech.slashdot.org/story/19/12/15/181240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Link in Bio' is a Slow Knife
by Peter Reutemann 15 Dec '19

15 Dec '19

'Anil Dash: We don't even notice it anymore -- "link in bio." It's a pithy phrase, usually found on Instagram, which directs an audience to be aware that a pertinent web link can be found on that user's profile. Its presence is so subtle, and so pervasive, that we barely even noticed it was an attempt to kill the web. Links on the web are incredibly powerful. There are decades of theory behind the role of hyperlinks in hypertext -- did you know in most early versions, links were originally designed to be two-way? You'd be able to see every page on the web that links to this one. But even in the very simple form that we've ended up with on the World Wide Web for the last 30 years, links are incredibly powerful, opening up valuable connections between unexpected things. For a closed system, those kinds of open connections are deeply dangerous. If anyone on Instagram can just link to any old store on the web, how can Instagram -- meaning Facebook, Instagram's increasingly-overbearing owner -- tightly control commerce on its platform? If Instagram users could post links willy-nilly, they might even be able to connect directly to their users, getting their email addresses or finding other ways to communicate with them. Links represent a threat to closed systems. Here's the thing, though: people like links. So closed systems have to present a pressure release valve. Hashtags are a great way out. They use the semiotics of links (early versions of hashtags on social platforms were really barely more than automated links to a search for a particular term) but are also constrained by the platforms they live on. A hashtag is easier to gather into a database, to harvest, to monetize. It's much easier, sure, but it also doesn't have all the messiness of a real link. Instagram doesn't have to worry that clicking on its hashtags will accidentally lead people to Twitter, or vice versa.' -- source: https://tech.slashdot.org/story/19/12/12/1540216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Building Your Own Open Source, Privacy-Protecting Voice Assistant With A Raspberry Pi
by Peter Reutemann 15 Dec '19

15 Dec '19

'PC Magazine's "tech nerd" Whitson Gordon writes that "Once you start using a smart speaker to set reminders, play the news, or turn the lights on, it's hard to go back." But if you want the convenience of voice control without the data-collecting tech giant behind the scenes, an open-source project called Mycroft is a great alternative. And you can run it right on a Raspberry Pi. Mycroft is a free, open-source voice assistant designed to run on Linux-based devices... Mycroft has been around for quite a few years, but it's recently gained a bit more notoriety thanks to privacy concerns surrounding data collection at Amazon and Google. Unlike those assistants, Mycroft only collects data if you opt in during setup. And for the users who do opt in, Mycroft promises never to sell your data to advertisers or third parties -- instead, it only uses it to help developers improve the product. Mycroft even uses the privacy-focused DuckDuckGo as its search engine instead of Google when you ask for information. Mycroft makes its own smart speaker called the Mark I, though it's currently sold out with a new Mark II (video here) on the way. However, since the project is open-source, you can install Mycroft on just about any Linux machine, including the Raspberry Pi (thanks to a pre-made build called Picroft). Using Mycroft on the Pi is free, but you can also subscribe to a $1.99-per-month plan to help support its development -- you'll even get a few goodies, like other voices that sound more lifelike than the default robotic voice.' -- source: https://hardware.slashdot.org/story/19/12/14/1954242 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Managing Spectre/Meltdown-Style Vulnerabilities At AWS
by Lawrence D'Oliveiro 15 Dec '19

15 Dec '19

Some insights <https://www.theregister.co.uk/2019/12/10/linux_kernel_aws/> into the different priorities often faced by different groups faced with the same problem. Linux kernel developer Greg Kroah-Hartman says to avoid most of these “MDS” (“Microarchitectural Data Sampling”) vulnerabilities, you must turn off Intel’s hyperthreading, full stop. Amazon, on the other hand, find that the resulting 30-40% performance loss is unacceptable for many of their customers. So they have come up with a tweaked scheduler algorithm for their Linux kernels that avoids running two different guests on the same physical core at the same time. With this and other careful management, they claim to be able to keep their customers safe from each other, with much less dramatic performance impact. But then you have the downside that the mainline kernel is not interested in accepting patches with such narrow applicability. Of course Amazon would like to come up with something they will accept, just to reduce their own maintenance burden.

Mozilla To Force All Add-on Devs To Use 2FA To Prevent Supply-Chain Attacks
by Peter Reutemann 14 Dec '19

14 Dec '19

'Mozilla announced this week that all developers of Firefox add-ons must enable a two-factor authentication (2FA) solution for their account. From a report: "Starting in early 2020, extension developers will be required to have 2FA enabled on AMO [the Mozilla Add-Ons portal]," said Caitlin Neiman, Add-ons Community Manager at Mozilla. "This is intended to help prevent malicious actors from taking control of legitimate add-ons and their users," Neiman added. When this happens, hackers can use the developers' compromised accounts to ship tainted add-on updates to Firefox users. Since Firefox add-ons have a pretty privileged position inside the browser, an attacker can use a compromised add-on to steal passwords, authentication/session cookies, spy on a user's browsing habits, or redirect users to phishing pages or malware download sites. These types of incidents are usually referred to as supply-chain attacks.' -- source: https://it.slashdot.org/story/19/12/13/152239 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Russian Police Raid NGINX Moscow Office
by Peter Reutemann 13 Dec '19

13 Dec '19

'Russian police have raided today the Moscow offices of NGINX, Inc., a subsidiary of F5 Networks and the company behind the internet's most popular web server technology. From a report: Equipment was seized and employees were detained for questioning. Moscow police executed the raid after last week the Rambler Group filed a copyright violation against NGINX Inc., claiming full ownership of the NGINX web server code. The Rambler Group is the parent company of rambler.ru, one of Russia's biggest search engines and internet portals. According to copies of the search warrant posted on Twitter today, Rambler claims that Igor Sysoev developed NGINX while he was working as a system administrator for the company, hence they are the rightful owner of the project. Sysoev created NGINX in the early 2000s and open-sourced the NGINX code in 2004. In 2009, he founded NGINX, Inc., a US company, to provide adjacent tools and support services for NGINX deployments. The company is based in San Francisco, but has offices all over the world, including Moscow. The NGINX server's source code is still free and managed through an open-source model, although a large chunk of the project's primary contributors are NGINX, Inc. employees, who have a firm grip on the project's stewardship.' -- source: https://news.slashdot.org/story/19/12/12/175245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Inside the Podcast that Hacks Ring Camera Owners Live on Air
by Peter Reutemann 13 Dec '19

13 Dec '19

'In the NulledCast podcast hackers livestream the harassment of Ring camera owners after accessing their devices. Hundreds of people can listen. From a report: A blaring siren suddenly rips through the Ring camera, startling the Florida family inside their own home. "It's your boy Chance on Nulled," a voice says from the Ring camera, which a hacker has taken over. "How you doing? How you doing?" "Welcome to the NulledCast," the voice says. The NulledCast is a podcast livestreamed to Discord. It's a show in which hackers take over people's Ring and Nest smarthome cameras and use their speakers to talk to and harass their unsuspecting owners. In the example above, Chance blared noises and shouted racist comments at the Florida family. "Sit back and relax to over 45 minutes of entertainment," an advertisement for the podcast posted to a hacking forum called Nulled reads. "Join us as we go on completely random tangents such as; Ring & Nest Trolling, telling shelter owners we killed a kitten, Nulled drama, and more ridiculous topics. Be sure to join our Discord to watch the shows live." Software to hack Ring cameras has recently become popular on the forum. The software churns through previously compromised email addresses and passwords to break into Ring cameras at scale. This has led to a recent spate of hacks that have occurred both during the podcast and at other times, several of which have been covered by local media outlets. In Brookhaven a hacker shouted at a sleeping woman through her hacked Ring camera to wake-up. In Texas, a hacker demanded a couple pay a bitcoin ransom. Hackers targeted a family in DeSoto County, Mississippi, and spoke through the device to one of the young children.' -- source: https://yro.slashdot.org/story/19/12/12/204240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel’s SGX coughs up crypto keys when scientists tweak CPU voltage
by Peter Reutemann 11 Dec '19

11 Dec '19

'To counter the growing sophistication of computer attacks, Intel and other chip makers have built digital vaults into CPUs to segregate sensitive computations and secrets from the main engine computers use. Now, scientists have devised an attack that causes the Software Guard Extensions—Intel's implementation of this secure CPU environment to divulge cryptographic keys and induce potentially dangerous memory errors. Plundervault, as the attack has been dubbed, starts with the assumption that an attacker is able to run privileged software on a targeted computer. While that's a lofty prerequisite, it's precisely the scenario Intel's SGX feature is designed to protect against. The chipmaker bills SGX as a private region that uses hardware-based memory encryption to isolate sensitive computations and data from malicious processes that run with high privilege levels. Intel goes as far as saying that "Only Intel SGX offers such a granular level of control and protection." But it turns out that subtle fluctuations in voltage powering the main CPU can corrupt the normal functioning inside the SGX. By subtly increasing or decreasing the current delivered to a CPU—operations known as "overvolting" and "undervolting"—a team of scientists has figured out how to induce SGX faults that leak cryptographic keys, break integrity assurances, and potentially induce memory errors that could be used in other types of attacks.' -- source: https://arstechnica.com/information-technology/2019/12/scientists-pluck-cry… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Are You One Of Avast's 400 Million Users? This Is Why It Collects And Sells Your Web Habits.
by Peter Reutemann 11 Dec '19

11 Dec '19

'Avast, the multibillion-dollar Czech security company, doesn't just make money from protecting its 400 million users' information. It also profits in part because of sales of users' Web browsing habits and has been doing so since at least 2013. From a report: That's led to some labelling its tools "spyware," the very thing Avast is supposed to be protecting users from. Both Mozilla and Opera were concerned enough to remove some Avast tools from their add-on stores earlier this month, though the anti-virus provider says it's working with Mozilla to get its products back online. But recently appointed chief executive Ondrej Vlcek tells Forbes there's no privacy scandal here. All that user information that it sells cannot be traced back to individual users, he asserts. Here's how it works, according to Vlcek: Avast users have their Web activity harvested by the company's browser extensions. But before it lands on Avast servers, the data is stripped of anything that might expose an individual's identity, such as a name in the URL, as when a Facebook user is logged in. All that data is analysed by Jumpshot, a company that's 65%-owned by Avast, before being sold on as "insights" to customers. Those customers might be investors or brand managers. What do those customers get? Vlcek says Jumpshot, which was initially acquired in 2013, provides "insights on how cohorts of users on the internet use the web." For instance, it could show a percentage of visitors who went from one website to another. That could be useful to anyone monitoring an advertising campaign. "Typical customers would be, for example, investors, who would be interested in how online companies are doing in terms of their new campaigns," the new Avast chief explains. Say Amazon launches a new product -- Jumpshot could determine how much interest it's getting online.' -- source: https://it.slashdot.org/story/19/12/10/1922243 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

WireGuard VPN is a step closer to mainstream adoption
by Peter Reutemann 10 Dec '19

10 Dec '19

'As of this morning, Linux network stack maintainer David Miller has committed the WireGuard VPN project into the Linux "net-next" source tree. Miller maintains both net and net-next—the source trees governing the current implementation of the Linux kernel networking stack and the implementation of the next Linux kernel's networking stack, respectively. This is a major step forward for the WireGuard VPN project. Net-next gets pulled into the new Linux kernel during its two-week merge window, where it becomes net. With WireGuard already a part of net-next, this means that—barring unexpected issues—there should be a Linux kernel 5.6 release candidate with built-in WireGuard in early 2020. Mainline kernel inclusion of WireGuard should lead to significantly higher uptake in projects and organizations requiring virtual private network capability. Normal, day-to-day Linux users probably won't see in-kernel WireGuard until late 2020. Ubuntu is one of the faster-moving mainstream distributions, and its next Long Term Support (LTS) release is in April 2020. But the Linux 5.6 kernel and Ubuntu 20.04 will likely be in release candidate status at the same time, so its inclusion in 20.04 seems unlikely. The interim 20.10 Ubuntu release seems like a much safer bet for Canonical's first use of a 5.6 or later kernel. Red Hat Enterprise Linux (RHEL) inclusion will likely be a year or more beyond that; the current RHEL 8.1 shipped in May 2019 with the 4.18 kernel, which was already 9 months old. Although highly speculative, it's also possible that WireGuard could land in-kernel on Ubuntu 20.04 even without the 5.6 kernel—Donenfeld offered to do the work backporting WireGuard into earlier Ubuntu kernels directly. Donenfeld also stated today that a 1.0 WireGuard release is "on the horizon."' -- source: https://arstechnica.com/gadgets/2019/12/wireguard-vpn-is-a-step-closer-to-m… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Users Can Now Use Disney+ After DRM Fix
by Peter Reutemann 09 Dec '19

09 Dec '19

'"Linux users can now stream shows and movies from the Disney+ streaming service after Disney lowered the level of their DRM requirements," reports Bleeping Computer: When Disney+ was first launched, Linux users who attempted to watch shows and movies were shown an error stating "Something went wrong. Please try again. If the problem persists, visit the Disney+ Help Center (Error Code 83)." As explained by Hans de Goede, this error was being caused by the Disney+ service using the highest level of security for the Widevine Digital Rights Management (DRM) technology. As some Linux and Android devices did not support this higher DRM security level, they were unable to stream Disney+ shows in their browsers... Yesterday, Twitter users discovered that Disney+ had suddenly started working on Linux browsers after the streaming service tweaked their DRM security levels... Even with Disney+ lowering the DRM requirements, users must first make sure DRM is enabled in the browser. For example, Disney+ will not work with Firefox unless you enable the "Play DRM-controlled content" setting in the browser.' -- source: https://linux.slashdot.org/story/19/12/08/169213 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Qualcomm To Offer GPU Driver Updates On Google Play Store For Some Snapdragon Chips
by Peter Reutemann 08 Dec '19

08 Dec '19

'At its Snapdragon Summit in Maui, Hawaii this week, Qualcomm unveiled the new Snapdragon 865 Mobile Platform, which enable next year's flagship 5G Android phones with more performance, a stronger Tensor-based AI processor and a very interesting new forthcoming feature not yet offered for any smartphone platform to date. The company announced that it will eventually start delivering driver updates for its Adreno GPU engines on board the Snapdragon 865 as downloadable packages via the Google Play Store. This is big news for smartphones, as GPU drivers are rarely updated out of band, if ever, and typically have to wait for the next major Android release. And even then, many OEMs don't bother putting in the effort to ensure that mobile GPUs are running the most current graphics drivers from Qualcomm. The process, which would have to be pre-qualified by major OEMs as well, will be akin to what the PC GPU 3D graphics driver ecosystem has been benefiting from for a long time, for maximum performance and compatibility. Unfortunately, at least currently, GPU driver update support is limited to only the Adreno 650 core on board the new Snapdragon 865, which currently supports updating drivers in this fashion. Here's hoping this program is met with success and Qualcomm will begin to enable the feature for legacy and new midrange Snapdragon platforms as well.' -- source: https://tech.slashdot.org/story/19/12/06/2132212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Keybase Moves To Stop Onslaught of Spammers on Encrypted Message Platform
by Peter Reutemann 07 Dec '19

07 Dec '19

'Keybase started off as co-founder and developer Max Krohn's "hobby project" -- a way for people to share PGP keys with a simple username-based lookup. Then Chris Coyne (who also was cofounder of OkCupid and SparkNotes) got involved and along came $10.8 million in funding from a group of investors led by Andreesen Horowitz. And then things got increasingly more complicated. Keybase aims to make public-key encryption accessible to everyone, for everything from messaging to file sharing to throwing a few crypto-coins someone's way. But because of that level of accessibility, Keybase faces a very OkCupid kind of problem: after drawing in people interested in easy public-key crypto-based communications and then drawing in blockchain lovers with its partnership with (and funding from) Stellar.org, Keybase has also drawn in spammers and scammers. And that has brought a host of alerts and messages that have made what was once a fairly clear communications channel into one clogged with unwanted alerts, messages, and other unpleasantry -- raising a chorus of complaints in Keybase's open chat channel. It turns out there's a reason spell check keeps wanting to tell me that Keybase should be spelled "debase." Keybase's leadership is promising to do something to fix the spam problem -- or at least make it easier to report and block abusers. In a blog post, Krohn and Coynes wrote, "To be clear, the current spam volume isn't dire, YET. Keybase still works great. But we should act quickly." But the measures promised by Keybase won't completely eliminate the issue. And Keybase execs have no interest in getting involved with additional steps that they see as censorship. "Keybase is a private company and we do retain our rights to kick people out," the co-founders said in the blog post.

New Linux Vulnerability Lets Attackers Hijack VPN Connections
by Peter Reutemann 06 Dec '19

06 Dec '19

'Security researchers found a new vulnerability allowing potential attackers to hijack VPN connections on affected *NIX devices and inject arbitrary data payloads into IPv4 and IPv6 TCP streams. They disclosed the security flaw tracked as CVE-2019-14899 to distros and the Linux kernel security team, as well as to others impacted such as Systemd, Google, Apple, OpenVPN, and WireGuard. The vulnerability is known to impact most Linux distributions and Unix-like operating systems including FreeBSD, OpenBSD, macOS, iOS, and Android. A currently incomplete list of vulnerable operating systems and the init systems they came with is available below, with more to be added once they are tested and found to be affected: Ubuntu 19.10 (systemd), Fedora (systemd), Debian 10.2 (systemd), Arch 2019.05 (systemd), Manjaro 18.1.1 (systemd), Devuan (sysV init), MX Linux 19 (Mepis+antiX), Void Linux (runit), Slackware 14.2 (rc.d), Deepin (rc.d), FreeBSD (rc.d), and OpenBSD (rc.d). This security flaw "allows a network adjacent attacker to determine if another user is connected to a VPN, the virtual IP address they have been assigned by the VPN server, and whether or not there is an active connection to a given website," according to William J. Tolley, Beau Kujath, and Jedidiah R. Crandall, Breakpointing Bad researchers at University of New Mexico. "Additionally, we are able to determine the exact seq and ack numbers by counting encrypted packets and/or examining their size. This allows us to inject data into the TCP stream and hijack connections," the researchers said.' -- source: https://linux.slashdot.org/story/19/12/05/2022205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Brother of Drug Lord Pablo Escobar Launches 'Unbreakable' Foldable Smartphone
by Peter Reutemann 05 Dec '19

05 Dec '19

'Roberto Escobar, brother of the late drug lord Pablo Escobar, has announced a foldable smartphone that is "very difficult to break" thanks to the screen's "special type of plastic." The Escobar Fold 1, as it is called, significantly undercuts Samsung's Galaxy Fold and Huawei Mate X with a price of only $349. Neowin reports: While all the foldable phones announced so far have a price tag of at least $1,500+, the Escobar Fold 1 will be available from only $349 which includes free shipping and a case as well. It will be sold unlocked and work on all compatible networks worldwide. This makes it cheaper than other non-foldable flagship smartphones available in the market right now.

The Rise and Fall of the PlayStation Supercomputers
by Peter Reutemann 04 Dec '19

04 Dec '19

'"On the 25th anniversary of the original Sony PlayStation, The Verge shares the story of the PlayStation supercomputers," writes Slashdot reader jimminy_cricket. From the report: Dozens of PlayStation 3s sit in a refrigerated shipping container on the University of Massachusetts Dartmouth's campus, sucking up energy and investigating astrophysics. It's a popular stop for tours trying to sell the school to prospective first-year students and their parents, and it's one of the few living legacies of a weird science chapter in PlayStation's history. Those squat boxes, hulking on entertainment systems or dust-covered in the back of a closet, were once coveted by researchers who used the consoles to build supercomputers. With the racks of machines, the scientists were suddenly capable of contemplating the physics of black holes, processing drone footage, or winning cryptography contests. It only lasted a few years before tech moved on, becoming smaller and more efficient. But for that short moment, some of the most powerful computers in the world could be hacked together with code, wire, and gaming consoles. "The game consoles entered the supercomputing scene in 2002 when Sony released a kit called Linux for the PlayStation 2," reports The Verge. Craig Steffen, senior research scientist at the National Center for Supercomputing Applications, and his group hooked up between 60 and 70 PlayStation 2s, wrote some code, and built out a library. "The PS3 entered the scene in late 2006 with powerful hardware and an easier way to load Linux onto the devices," the report adds. "Researchers would still need to link the systems together, but suddenly, it was possible for them to imagine linking together all of those devices into something that was a game-changer instead of just a proof-of-concept prototype."' -- source: https://hardware.slashdot.org/story/19/12/03/2214249 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

elementary OS 5.1 'Hera' Linux Distro is Here
by Peter Reutemann 04 Dec '19

04 Dec '19

'elementary OS has long been viewed by many as the future of Linux on the PC thanks to its beautiful desktop environment and overall polished experience. Development of the Ubuntu-based operating system has been frustratingly slow, however. This shouldn't be surprising, really, as the team of developers is rather small, and its resources are likely much less than those of larger distributions such as the IBM-backed Fedora or Canonical's Ubuntu. And that is what makes elementary OS so remarkable -- its developers can make magic on a smaller budget. Today, the latest version of the operating system is released. Code-named "Hera," elementary OS 5.1 is now available for download. Support for Flatpak is now baked in -- this is significant, as the developers explain it is "the first non-deb packaging format we've supported out of the box." The Linux kernel now sits at a very modern 5.0. One of the most important aspects of elementary OS, the AppCenter, is now an insane 10 times faster than its predecessor.' -- source: https://tech.slashdot.org/story/19/12/03/1538207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Removes Avast and AVG Extensions From Add-on Portal Over Snooping Claims
by Peter Reutemann 04 Dec '19

'Mozilla today removed four Firefox extensions made by Avast and its subsidiary AVG after receiving credible reports that the extensions were harvesting user data and browsing histories. From a report: The four extensions are Avast Online Security, AVG Online Security, Avast SafePrice, and AVG SafePrice. The first two are extensions that show warnings when navigating to known malicious or suspicious sites, while the last two are extensions for online shoppers, showing price comparisons, deals, and available coupons. Mozilla removed the four extensions from its add-ons portal after receiving a report from Wladimir Palant, the creator of the AdBlock Plus ad-blocking extension. Palant analyzed the Avast Online Security and AVG Online Security extensions in late October and found that the two were collecting much more data than they needed to work -- including detailed user browsing history, a practice prohibited by both Mozilla and Google.' -- source: https://yro.slashdot.org/story/19/12/03/1559248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Vulnerability In Fully Patched Android Phones Under Active Attack By Bank Thieves
by Peter Reutemann 03 Dec '19

03 Dec '19

'A vulnerability in millions of fully patched Android phones is being actively exploited by malware that's designed to drain the bank accounts of infected users, researchers said on Monday. The vulnerability allows malicious apps to masquerade as legitimate apps that targets have already installed and come to trust, researchers from security firm Promon reported in a post. Running under the guise of trusted apps already installed, the malicious apps can then request permissions to carry out sensitive tasks, such as recording audio or video, taking photos, reading text messages or phishing login credentials. Targets who click yes to the request are then compromised. Researchers with Lookout, a mobile security provider and a Promon partner, reported last week that they found 36 apps exploiting the spoofing vulnerability. The malicious apps included variants of the BankBot banking trojan. BankBot has been active since 2017, and apps from the malware family have been caught repeatedly infiltrating the Google Play Market. The vulnerability is most serious in versions 6 through 10, which account for about 80% of Android phones worldwide. Attacks against those versions allow malicious apps to ask for permissions while posing as legitimate apps. There's no limit to the permissions these malicious apps can seek. Access to text messages, photos, the microphone, camera, and GPS are some of the permissions that are possible. A user's only defense is to click "no" to the requests. "The vulnerability is found in a function known as TaskAffinity, a multitasking feature that allows apps to assume the identity of other apps or tasks running in the multitasking environment," reports Ars Technica. While Google has removed the [unnamed] malicious apps from its Play Store, according to Promon, the vulnerability is still unfixed in all versions of Android. "Promon is calling the vulnerability 'StrandHogg,' an old Norse term for the Viking tactic of raiding coastal areas to plunder and hold people for ransom," the report adds. "Promon researchers said they identified StrandHogg after learning from an unnamed Eastern European security company for financial institutions that several banks in the Czech Republic reported money disappearing from customer accounts."' -- source: https://it.slashdot.org/story/19/12/02/230254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Huawei Is Now Making Smartphones Without American Chips
by Peter Reutemann 03 Dec '19

03 Dec '19

'"American tech companies are getting the go-ahead to resume business with Chinese smartphone giant Huawei Technologies Co., but it may be too late," reports the Wall Street Journal. Huawei is just building its smartphones without U.S. chips. Huawei's latest phone, which it unveiled in September -- the Mate 30 with a curved display, telephone and wide-angle cameras that competes with Apple Inc.'s iPhone 11 -- contained no U.S. parts, according to an analysis by UBS and Fomalhaut Techno Solutions, a Japanese technology lab that took the device apart to inspect its insides... While Huawei hasn't stopped using American chips entirely, it has reduced its reliance on U.S. suppliers or eliminated U.S. chips in phones launched since May, including the company's Y9 Prime and Mate smartphones, according to Fomalhaut's teardown analysis. Similar inspections by iFixit and Tech Insights Inc., two other firms that take apart phones to inspect components, have come to similar conclusions.' -- source: https://mobile.slashdot.org/story/19/12/02/0146208 Looks like actual competition now...

Rust-Based Redox OS Is Nearly Self-Hosting After Four Years
by Peter Reutemann 02 Dec '19

02 Dec '19

'Redox OS, written in Rust and currently under development, is only "a few months of work away" from self-hosting, meaning that the Rustc compiler would run on Redox itself, according to its creator Jeremy Soller... Redox has a POSIX-compliant C library written in Rust, called relibc. It is Linux-compatible both at the syscall API level and at the syscall ABI (Application binary interface) level, subject to the same architecture. The article notes that the OS's latest release was version 0.5 last March, arguing that it's "best described as experimental..." "Still, if Rust continues to grow in popularity, its characteristics of safety and unimpeded performance seem ideal for creating a new operating system, so perhaps Redox will become more prominent."' -- source: https://linux.slashdot.org/story/19/11/30/2011231 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Kali Linux Adds 'Undercover' Mode to Impersonate Windows 10
by Peter Reutemann 02 Dec '19

02 Dec '19

'"Kali Linux 2019.4 was released last week and with it comes an 'Undercover' mode that can be used to quickly make the Kali desktop look like Windows 10," reports Bleeping Computer: Kali is a Linux distribution created for ethical hacking and penetration testing and is commonly used by researchers and red teamers to perform security tests against an organization. As most people are used to seeing Windows and macOS devices being used, it may look suspicious to see a user running Kali Linux with it's distinctive dragon logo and a Linux environment in an office lobby or other public setting. With this in mind, in Kali Linux 2019.4 the developers created a new 'Undercover' mode that will make the desktop look similar to Windows 10 in order to draw less suspicion. The script even hides Kali's dragon logo, explains a post on the Kali blog, so "you can work a bit more incognito. After you are done and in a more private place, run the script again and you switch back to your Kali theme. Like magic...!" "Thanks to Robert, who leads our penetration testing team, for suggesting a Kali theme that looks like Windows to the casual view..."' -- source: https://linux.slashdot.org/story/19/12/01/1825215 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Ubuntu 19.10: It’s fast, like “make old hardware feel new” fast
by Peter Reutemann 28 Nov '19

28 Nov '19

'Leaves are turning. Temperatures have dipped. These are sure signs—if you live in the Northern Hemisphere, at least—that Canonical's Autumn release is upon us. Things are a bit different in 2019, however. Not only is Ubuntu 19.10 nicknamed Eoan Ermine (no, I don't know how you pronounce it either), but it's the best non-LTS Ubuntu release Canonical has ever put out. I should qualify that statement somewhat, because really, as the newest version, it had damn well better be the best Ubuntu ever. But there's more than recency bias behind the sentiment. I've been reviewing Ubuntu for 10 years now, and I was using and interacting with this distro in some form or another for another three or four years before that. After spending recent weeks with Ubuntu 19.10, I can say confidently it is quite simply the best Ubuntu Canonical has ever released. The first reason I like 19.10 so much is that it feels insanely fast. Everyday tasks like opening applications, dragging windows, activating the search interface, and even just moving the cursor around are all noticeably faster than in 19.04. The speed boost is immediately noticeable from the minute you pop in the live CD, and it's even faster once you have 19.10 installed. I happened to be testing a top-of-the-line MacBook around the time I first installed the 19.10 beta on my aging Lenovo x240, and it instantly made the Mac feel like a sloth. Ubuntu 19.10 ran circles around the Mac even on much, much less powerful hardware, and nothing says success during testing like software that makes old hardware feel newer. Even if that were all you got out of Ubuntu 19.10, I'd call it a win.' -- source: https://arstechnica.com/gadgets/2019/11/ubuntu-19-10-quite-simply-the-best-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Just came across this video <https://www.youtube.com/watch?v=VJC6OpGpq0Y>, latest in a series on cooling solutions for a Raspberry π 4. This instalment looks at a couple of purely passive, fanless products that use the case as a heat sink (or vice versa). But on top of that, a recent firmware update from Broadcom has made a massive difference to the running temperature in all the configurations. Summary: passive cooling worked quite well before the update, and now works even better.

The Librem 5 has been “shipping” for a month—but not to backers
by Peter Reutemann 26 Nov '19

26 Nov '19

'Purism announced that shipping of its Librem 5 open source smartphone began in late September. Two months later, nobody outside the company has a Librem 5, and people are getting restless. The Librem 5 is a crowdfunded project—and an ambitious one—so it wasn't much surprise or cause for concern when it missed its original January 2019 delivery target—or the April 2019 target set after January slipped. Both date changes were announced well ahead of time, and the company continued to post progress reports, commit code upstream, and assure backers of its commitment to transparency. (Full disclosure: I am a Librem 5 backer myself and am scheduled to receive a phone in the Evergreen batch.) The new delays are more troubling. On September 5, CEO Todd Weaver announced that the Librem 5 would ship in six iterative batches, codenamed Aspen, Birch, Chestnut, Dogwood, Evergreen, and Fir. The first three batches would effectively be usable prototypes of decreasing roughness; Evergreen would be the first entirely finished hardware production run, and Fir would be a relatively unspecified next-generation design.' -- source: https://arstechnica.com/gadgets/2019/11/the-librem-5-has-been-shipping-for-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla's Annual Buyer's Guide Rates Amazon and Google Security Cameras 'Very Creepy'
by Peter Reutemann 26 Nov '19

26 Nov '19

'"Be Smart. Shop Safe," warns Mozilla's annual buyer's guide for secure connected products. Based on their conversations with developers and dozens of privacy experts, they've awarded smiley faces with different expressions to rate products from "Not Creepy" up to "Super Creepy". "While the variety of smart devices on offer is rapidly increasing, so are the number of products that pay no heed to even basic security measures..." notes the editor of Mozilla's Internet Health Report. "Now that more and more companies collect personal data about you, including audio and video of your family, and sensitive biometric and health information, like your heart rate and sleeping habits, it's worrying that more are not upfront about the privacy and security of their products." Or, as The Next Web writes, "god bless Mozilla for having our lazy backs." And, well, if you're a user of any Ring camerasâ¦ we're sorry. Basically, there are five things that every product must do: - Have automatic security updates, so they're protected against the newest threats - Use encryption, meaning bad actors can't just snoop on your data - Include a vulnerability management pathway, which makes reporting bugs easy and, well, possible - Require users to change the default password (if applicable), because that makes devices far harder to access - Privacy policies -- ones that relate to the product specifically, and aren't just generic Doesn't seem too much to ask right...? Well, of the 76 devices Mozilla selected, 60 of them passed this test... And what devices didn't meet the criteria? There were nine of them overall (including the Artie 3000 Coding Robot and the Wemo Wifi Smart Dimmer), but the real loser in this test is the Amazon-owned Ring. Three of the company's products (which is effectively all of their major devices) didn't meet Mozilla's criteria. Yes, that's right, the Ring Video Doorbell, Ring Indoor Cam, and Ring Security Cam all didn't meet minimum standards for security.... The main reasons for not meeting this criteria is due Ring's history with poor encryption policies, and vulnerability management. To be fair, Nest Cam's Indoor and Outdoor Security Cameras and Google Home also fell into the "Very Creepy" category -- and so did Amazon's Echo smart speakers. (The Amazon Echo Show even made it into Mozilla's highest "Super Creepy" category, where the only other product was Facebook Portal.) But at least the Nest Hello Video doorbell only appears in Mozilla's "Somewhat Creepy" category. "Just because something on your wishlist this year connects to the internet, doesn't mean you have to compromise on privacy and security..." warns the editor of Mozilla's Internet Health Report. And in addition, "Fitness trackers designed for kids as young as 4 years old, raise questions about what we are teaching our children about how much digital surveillance in their lives is normal." Going forward, they suggest that we push for better privacy regulations -- and that whenever we rate products on performance and price, we should also rate them on their privacy and security. But in the meantime, as Mozilla explained on Twitter, "Friends don't let friends buy creepy gifts."' -- source: https://yro.slashdot.org/story/19/11/25/0415202 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Web Creator Tim Berners-Lee Launches Plan To 'Fix' the Internet
by Peter Reutemann 26 Nov '19

26 Nov '19

'Tim Berners-Lee, the creator of the World Wide Web, is officially launching his plan to "fix" the internet. From a report: The World Wide Web Foundation, a non-profit campaign group set up by Berners-Lee, has secured the backing of tech giants Facebook, Google and Microsoft for the scheme, dubbed the "contract for the web." The British computer scientist first outlined his vision to overhaul organizations' approach to the internet at the Web Summit event last year. At the time, he said the web was "at a tipping point." The contract calls on companies to respect consumers' data privacy and urges governments to ensure everyone has access to the internet. "Never before has the web's power for good been more under threat," Adrian Lovett, CEO of the World Wide Web Foundation, told CNBC in an interview Friday. He added that the rise of hateful content and fake news being propagated online meant something had to change. "We're launching the contract for the web for the world's first-ever global action plan to protect the web as a force for good, bringing together companies, governments and citizens from around the world to say these are the things that need to be done to put things back on the right track." Other organizations backing the contract include DuckDuckGo, Reddit, GitHub and Reporters Without Borders. One major component of the pledge is the requirement that the web remains an accessible tool for all users. Lovett said that, "despite the progress we've seen in getting the world connected, half the world doesn't have access." He said the contract comes with nine core principles, while underneath them is a total of 76 clauses. "Not every organization has to abide by all of them," he insisted. "A good number of those 76 will be relevant." Berners-Lee will deliver a speech in Berlin, Germany, on Monday where he is due to say the contract will serve as a blueprint for governments, companies and citizens to safeguard the web as a force for good. The World Wide Web Foundation says it is working with partners to develop tools that can measure progress on the contract's various clauses' -- source: https://yro.slashdot.org/story/19/11/25/1347233 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Zorin OS 15 Lite Linux Distro Can Rejuvenate Your Aging Windows PC
by Peter Reutemann 26 Nov '19

'Called "Zorin OS 15 Lite," it is not only lightweight, but thanks to the Xfce desktop environment and integrated Flatpak support, it should be quite familiar to those switching from Windows. In fact, the developers are intentionally targeting existing Windows 7 users, as Microsoft's operating system will be unsupported beginning January 2020. Zorin OS 15 Lite, in comparison, is based on Ubuntu 18.04 LTS and supported until 2023! It even comes with the very modern Linux kernel 5.0. "With Zorin OS 15 Lite, weâ(TM)ve condensed the full Zorin OS experience into a streamlined operating system, designed to run fast on computers as old as 15 years. With version 15, we've gone the extra mile to make the XFCE 4.14-based desktop feel familiar and user-friendly to new users, especially those moving away from Windows 7 leading up to the end of its support in January 2020. By pairing the most advanced and efficient software with a user-friendly experience, we've made it possible for anyone to extend the lifespan of their computers for years to come," explains the Zorin OS developers.' -- source: https://linux.slashdot.org/story/19/11/25/179256 Maybe worth a demo next year?

The RIPE NCC Has Run Out of IPv4 Addresses
by Peter Reutemann 26 Nov '19

26 Nov '19

'The RIPE NCC, the regional internet registry for Europe, West Asia, and the former USSR, has allocated the final /22 remaining in their address pool, and has stated that they have now run out of IPv4 addresses. RIPE will continue to recover IPv4 addresses from organisations that go out of business, close, or that return them due to lack of need, but expects these small amounts of recovered IPv4 addresses to fall well short of demand: RIPE will now only assign IPv4 addresses to entities that have never received any IPv4 allocation in the past, and even then will assign no more than a /24. RIPE puts out a call to action for IPv6 migration: This event is another step on the path towards global exhaustion of the remaining IPv4 addressing space. In recent years, we have seen the emergence of an IPv4 transfer market and greater use of Carrier Grade Network Address Translation (CGNAT) in our region. There are costs and trade-offs with both approaches and neither one solves the underlying problem, which is that there are not enough IPv4 addresses for everyone. Without wide-scale IPv6 deployment, we risk heading into a future where the growth of our Internet is unnecessarily limited — not by a lack of skilled network engineers, technical equipment or investment -- but by a shortage of unique network identifiers. There is still a long way to go, and we call on all stakeholders to play their role in supporting the IPv6 roll-out.' -- source: https://tech.slashdot.org/story/19/11/25/1841256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

That browser, which is available for beta testing now on all supported versions of Windows and MacOS, includes a feature called Tracking Prevention. If that name sounds familiar, you're not imagining things. Microsoft added a Tracking Protection feature to Internet Explorer 9, back in 2011; it used simple text files called Tracking Protection Lists (TPLs) to allow or block third-party requests from specific domains. That's the same general principle behind Tracking Prevention in the new Edge, but the implementation is more usable and more sophisticated, with multiple Trust Protection Lists taking the place of a single TPL. I've spent the past week looking closely at this feature... [A]lthough it's aimed at the online advertising and tracking industries in general, my tests suggest that its effects are likely to be felt most directly by one company: Google. Using the default Balanced setting, Tracking Prevention blocked a total of 2,318 trackers, or an average of 35 on each page. Of that total, 552 were from Google domains. That's a mind-boggling 23.8% of the total. To put that into perspective, the second entry on the list of blocked trackers was Facebook, which represented 3.8% of the total. Rather than an anti-Google conspiracy, the article suggests this is instead just a reflection of both Google's ubiquity and its business model. "Google Analytics and Google AdSense are embedded on a staggering number of web pages."' -- source: https://tech.slashdot.org/story/19/11/24/2055219 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Mint 19.2
by tom butz 23 Nov '19

23 Nov '19

Re: Linux Mint 19.2 The latest update ('new' package-manager) seems to disable Bluetooth. That also happened to me when I updated from 19.1 to 19.2 WITHOUT a complete reinstall. There are two workarounds: EITHER: back-up the whole system every night, and restore it if Bluetooth disappears again (=no icon in the panel after an update) - skipping updates. OR: use another system such as SparkyLinux, e.g. on a bootable sdcard for Bluetooth-transfers and stick with Mint 19.2 for anything else. I use this 'veteran' Linux because it features OpenShot 1.4 - my (favourite) moviemaker. My Toshiba laptop has 128 GB of RAM-HD, so copying/restoring to/from an image-file doesn't take all that long.

The Ad Tracker Arms Race Continues
by Lawrence D'Oliveiro 22 Nov '19

22 Nov '19

Web advertisers are resorting to a new technique <https://www.theregister.co.uk/2019/11/21/ublock_origin_firefox_unblockable_…> to bypass restrictions on third-party cookies for tracking users’ browsing behaviour: use first-party cookies instead. A detailed example can be found in this GitHub issue <https://github.com/uBlockOrigin/uBlock-issues/issues/780>: the site www.liberation.fr includes links to f7ds.liberation.fr, which is notionally under the same domain. However, that is actually a CNAME (alias) for the third-party tracker site liberation.eulerian.net. So cookies that are supposed to be restricted to *.liberation.fr are passed to that site as well. Just to be clear, this is not a browser “bug” by any means; it’s just part of how the DNS is supposed to work. The good news is, Firefox offers an API that adblocker addons can use to detect this sort of thing going on and stop it.

System76 Will Start Designing and Building Its Own Linux Laptops Beginning January 2020
by Peter Reutemann 21 Nov '19

21 Nov '19

'Denver-based PC manufacturer and Pop!_OS Linux developer System76 plans to follow-up its custom Thelio desktop PC with an in-house laptop beginning next year, according to founder and CEO Carl Richell. During a recent interview, Richell was quick to emphasize that the entire process of designing, prototyping and iterating the final product could take two to three years. But the company is eager to break into this market and put the same signature "stamp" on its laptop hardware that graces its custom-built Thelio desktop. System76 sells an extensive lineup of laptops, but the machines are designed by the likes of Sager and Clevo. The company doesn't merely buy a chassis and slap Pop!_OS on it, but Richell tells me he's confident that with the experience gained from developing Thelio -- and the recent investment into a factory at the company's Denver headquarters -- System76 is capable of building a laptop from the ground up that meets market needs and carries a unique value proposition. Richell says the company's first priority is locking down the aesthetic of the laptop and how various materials look and feel. It will simultaneously begin working on the supply chain aspects and speaking with various display and component manufacturers. System76 will design and build a U-class laptop first (basically an Ultrabook form factor like the existing Darter and Galago) and then evaluate what it might do with higher-end gaming and workstation notebooks with dedicated graphics.' -- source: https://hardware.slashdot.org/story/19/11/20/2241223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

“Where the Wi-Fi sucks” is where a new wireless protocol does its magic
by Peter Reutemann 21 Nov '19

21 Nov '19

'Researchers at Brigham Young University have created a new RF protocol that runs on top of existing consumer Wi-Fi at significantly greater range. But before you get too excited, the protocol's bandwidth is extremely low—so much so that it makes LoRa look like an OC-24. The protocol, called ONPC—short for On-Off Noise Power Communication—currently only specifies a single bit per second. Although ONPC only conveys one bit per second of data, its range is 60m or more beyond Wi-Fi—and it runs in software alone, on unmodified Wi-Fi hardware. An ONPC device can connect to standard Wi-Fi when range permits, fall back to ONPC mode if the connection drops, and then re-connect to the Wi-Fi when it becomes available again.' -- source: https://arstechnica.com/gadgets/2019/11/where-the-wi-fi-sucks-is-where-a-ne… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google outlines plans for mainline Linux kernel support in Android
by Peter Reutemann 20 Nov '19

20 Nov '19

'It seems like Google is working hard to update and upstream the Linux kernel that sits at the heart of every Android phone. The company was a big participant in this year's Linux Plumbers Conference, a yearly meeting of the top Linux developers, and Google spent a lot of time talking about getting Android to work with a generic Linux kernel instead of the highly-customized version it uses now. It even showed an Android phone running a mainline Linux kernel. But first, some background on Android's current kernel mess.Currently, three major forks happen in between the "mainline" Linux kernel and a shipping Android device (note that "mainline" here has no relation to Google's own "Project Mainline"). First, Google takes the an LTS (Long Term Support) Linux kernel and turns it into the "Android Common kernel"—the Linux kernel with all the Android OS-specific patches applied. Android Common is shipped to the SoC vendor (usually Qualcomm) where it gets its first round of hardware-specific additions, first focusing on a particular model of SoC. This "SoC Kernel" then gets sent to a device manufacturer for even more hardware-specific code that supports every other piece of hardware, like the display, camera, speakers, usb ports, and any extra hardware. This is the "Device Kernel," and it's what actually ships on a device.' -- source: https://arstechnica.com/gadgets/2019/11/google-outlines-plans-for-mainline-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google and Samsung Fix Android Spying Flaw. Other Makers May Still Be Vulnerable
by Peter Reutemann 20 Nov '19

20 Nov '19

'Until recently, weaknesses in Android camera apps from Google and Samsung made it possible for rogue apps to record video and audio and take images and then upload them to an attacker-controlled server -- without any permissions to do so. Camera apps from other manufacturers may still be susceptible. From a report: The weakness, which was discovered by researchers from security firm Checkmarx, represented a potential privacy risk to high-value targets, such as those preyed upon by nation-sponsored spies. Google carefully designed its Android operating system to bar apps from accessing cameras and microphones without explicit permission from end users. An investigation published Tuesday showed it was trivial to bypass those restrictions. The investigation found that an app needed no permissions at all to cause the camera to shoot pictures and record video and audio. To upload the images and video -- or any other image and video stored on the phone -- to an attacker-controlled server, an app needed only permission to access storage, which is among one of the most commonly given usage rights. The weakness, which is tracked as CVE-2019-2234, also allowed would-be attackers to track the physical location of the device, assuming GPS data was embedded into images or videos. Google closed the eavesdropping hole in its Pixel line of devices with a camera update that became available in July. Checkmarx said Samsung has also fixed the vulnerability, although it wasn't clear when that happened. Checkmarx said Google has indicated that Android phones from other manufacturers may also be vulnerable. The specific makers and models haven't been disclosed.' -- source: https://tech.slashdot.org/story/19/11/19/1737219 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The World's Fastest Supercomputers Hit Higher Speeds Than Ever With Linux
by Peter Reutemann 19 Nov '19

19 Nov '19

'In the latest Top 500 supercomputer ratings, the average speed of these Linux-powered racers is now an astonishing 1.14 petaflops. The fastest of the fast machines haven't changed since the June 2019 Top 500 supercomputer list. Leading the way is Oak Ridge National Laboratory's Summit system, which holds top honors with an HPL result of 148.6 petaflops. This is an IBM-built supercomputer using Power9 CPUs and NVIDIA Tesla V100 GPUs. In a rather distant second place is another IBM machine: Lawrence Livermore National Laboratory's Sierra system. It uses the same chips, but it "only" hit a speed of 94.6 petaflops. Close behind at No. 3 is the Sunway TaihuLight supercomputer, with an HPL mark of 93.0 petaflops. TaihuLight was developed by China's National Research Center of Parallel Computer Engineering and Technology (NRCPC) and is installed at the National Supercomputing Center in Wuxi. It is powered exclusively by Sunway's SW26010 processors. Sunway's followed by the Tianhe-2A (Milky Way-2A). This is a system developed by China's National University of Defense Technology (NUDT). It's deployed at the National Supercomputer Center in China. Powered by Intel Xeon CPUs and Matrix-2000 accelerators, it has a top speed of 61.4 petaflops. Coming at No. 5, the Dell-built, Frontera, a Dell C6420 system is powered by Intel Xeon Platinum processors. It speeds along at 23.5 petaflops. It lives at the Texas Advanced Computing Center of the University of Texas. The most powerful new supercomputer on the list is Rensselaer Polytechnic Institute Center for Computational Innovations (CCI)'s AiMOS. It made the list in the 25th position with 8.0 petaflops. The IBM-built system, like Summit and Sierra, is powered by Power9 CPUs and NVIDIA V100 GPUs. In closing, ZDNet's Steven J.

Intel To Remove Old Drivers and BIOS Updates From Its Site
by Peter Reutemann 19 Nov '19

19 Nov '19

'By Friday this week, Intel plans to remove old drivers and BIOS updates from its official website. From a report: "This download, BIOS Update [BLH6710H.86A] 0163, will no longer be available after November 22, 2019 and will not be supported with any additional functional, security, or other updates," reads a message posted to the download page of one of the impacted components. "Intel recommends that users of BIOS Update [BLH6710H.86A] 0163 uninstall and/or discontinue use as soon as possible," the message continues. The downloads are drivers and BIOS updates for Intel desktop components and motherboards the company released in the 90s and early-to-mid 2000s. Downloads for hundreds of components are believed to have been impacted, from motherboards to NIC cards and graphics cards. Most of the drivers are for Windows versions like 98, ME, XP, and older Windows Server editions -- old Windows OS versions that have themselves reached end-of-life (EOL) All components and motherboards reached (EOL) years ago, and Intel stopped delivering firmware updates as a result. Its website was merely hosting the older files for convenience.' -- source: https://it.slashdot.org/story/19/11/18/1646210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Announces Plan To Support DoH In Windows
by Peter Reutemann 19 Nov '19

19 Nov '19

'Microsoft's Core Network team just announced they plan on supporting DoH in the Windows resolver. In the blog post, the company writes: Providing encrypted DNS support without breaking existing Windows device admin configuration won't be easy. However, at Microsoft we believe that "we have to treat privacy as a human right. We have to have end-to-end cybersecurity built into technology." We also believe Windows adoption of encrypted DNS will help make the overall Internet ecosystem healthier. There is an assumption by many that DNS encryption requires DNS centralization. This is only true if encrypted DNS adoption isn't universal. To keep the DNS decentralized, it will be important for client operating systems (such as Windows) and Internet service providers alike to widely adopt encrypted DNS. With the decision made to build support for encrypted DNS, the next step is to figure out what kind of DNS encryption Windows will support and how it will be configured. Here are our team's guiding principles on making those decisions: Windows DNS needs to be as private and functional as possible by default without the need for user or admin configuration because Windows DNS traffic represents a snapshot of the user's browsing history. To Windows users, this means their experience will be made as private as possible by Windows out of the box. For Microsoft, this means we will look for opportunities to encrypt Windows DNS traffic without changing the configured DNS resolvers set by users and system administrators. Privacy-minded Windows users and administrators need to be guided to DNS settings even if they don't know what DNS is yet. Many users are interested in controlling their privacy and go looking for privacy-centric settings such as app permissions to camera and location but may not be aware of or know about DNS settings or understand why they matter and may not look for them in the device settings. Windows users and administrators need to be able to improve their DNS configuration with as few simple actions as possible. We must ensure we don't require specialized knowledge or effort on the part of Windows users to benefit from encrypted DNS. Enterprise policies and UI actions alike should be something you only have to do once rather than need to maintain. Windows users and administrators need to explicitly allow fallback from encrypted DNS once configured. Once Windows has been configured to use encrypted DNS, if it gets no other instructions from Windows users or administrators, it should assume falling back to unencrypted DNS is forbidden.' -- source: https://yro.slashdot.org/story/19/11/18/1929229 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Why Firefox Fights for the Future of the Web
by Peter Reutemann 18 Nov '19

18 Nov '19

'"Mozilla is no longer fighting for market share of its browser: it is fighting for the future of the web," writes the Guardian, citing Mozilla Project co-founder Mitchell Baker: Baker's pitch is that only Mozilla is motivated, first and foremost, to make using the web a pleasurable experience. Google's main priority is to funnel user data into the enormous advertising engine that accounts for most of its revenue. Apple's motivation is to ensure that customers continue to buy a new iPhone every couple of years and don't switch to Android...." Firefox now runs sites such as Facebook in "containers", effectively hiving the social network off into its own little sandboxed world, where it can't see what's happening on other sites. Baker says: "It reduces Facebook's ability to follow you around the web and track you when you're not on Facebook and just living your life...." Mozilla has launched Monitor, a data-breach reporting service; Lockwise, a password manager; and Send, a privacy-focused alternative to services such as WeSendit. It's also beta-testing a VPN (virtual private network) service, which it hopes to market to privacy-conscious users... Apple's iOS (mobile operating system) is an acknowledged disaster for Mozilla. Safari is the default and, while users can install other browsers, they come doubly hindered: they can never be set as the default, meaning any link clicked in other applications will open in Safari; and they must use Safari's "rendering engine", a technical limitation that means that even the browsers that Firefox does have on the platform are technically just fancy wrappers for Apple's own browser, rather than full versions of the service that Mozilla has built over the decades... "Even if you do download a replacement, iOS drops you back into the default. I don't know why that's acceptable. Every link you open on a phone is the choice of the phone maker, even if you, as a user, want something else." Summarizing Baker's concerns, the Guardian writes that "It is perfectly possible to build a browser that prevents advertising companies from aggregating user data. But it is unlikely that any browser made by an advertising company would offer such a feature..." And an activist for the Small Technology Foundation tells them that Google "wants the web to go through Google. It already mostly does: with eyes on 70% to 80% of the web."' -- source: https://news.slashdot.org/story/19/11/17/1614222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Wikipedia's Co-Founder Takes On Facebook With Ad-Free Social Network
by Peter Reutemann 15 Nov '19

15 Nov '19

'Wikipedia co-founder Jimmy Wales has launched a social network called WT:Social. It has no financial association with Wikipedia and operates on donations, not advertising. The Next Web reports: WT:Social went live last month and is currently nearing 50,000 users. The company is rolling out access slowly; when I signed up, I was approximately number 28,000 on the waitlist. Alternatively, you can pay 13 bucks a month or 100 a year to get access right away. In comments to the Financial Times, Wales said "The business model of social media companies, of pure advertising, is problematic. It turns out the huge winner is low-quality content." You don't say. WT:Social's interface is rather sparse at the moment, featuring a simple feed comprised of news stories and comments below them. News is a big part of the network; it's a spinoff of Wales' previous project, WikiTribune, which sought to be a global news site comprised of professional journalists and citizen contributors. Both WikiTribune and WT:Social emphasize combatting fake news, highlighting evidence-based coverage over the focus on "engagement" seen on other networks. Each story posted to the network makes prominent where the article comes from, as well as sources and references. You can also join various "SubWikis" that are essentially like Facebook groups or subreddits, which filter content to stories of a given topic. You can also add hashtags to a post or follow hashtags for more specific interests that might span more than one SubWiki. Posts are currently sorted chronologically, but the site plans to add an upvote system for users to promote quality stories.' -- source: https://news.slashdot.org/story/19/11/14/223256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Windows and Linux Get Options To Disable Intel TSX To Prevent Zombieload v2 Attacks
by Peter Reutemann 15 Nov '19

15 Nov '19

'Both Microsoft and the Linux kernel teams have added ways to disable support for Intel Transactional Synchronization Extensions (TSX). From a report: TSX is the Intel technology that opens the company's CPUs to attacks via the Zombieload v2 vulnerability. Zombieload v2 is the codename of a vulnerability that allows malware or a malicious threat actor to extract information processed inside a CPU, information to which they normally shouldn't be able to access due to the security walls present inside modern-day CPUs. This new vulnerability was disclosed earlier this week. Intel said it would release microcode (CPU firmware) updates -- available on the company's Support & Downloads center. But, the reality of a real-world production environment is that performance matters. Past microcode updates for other attacks, such as Meltdown, Spectre, Foreshadow, Fallout, and Zombieload v1, have been known to introduce performance hits of up to 40%. Seeing that all the CPU attacks listed above are not only theoretical but also hard to pull off, some companies don't see this performance hit as an option.' -- source: https://tech.slashdot.org/story/19/11/14/1654247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GitHub Places Open-Source Code In Arctic Cave For Safekeeping

'GitHub's CEO Nat Friedman traveled to Svalbard in October to stash Linux, Android, and 6,000 other open-source projects in a permafrost-filled, abandoned coal mine.

Mozilla, Intel, and More Form the Bytecode Alliance To Take WebAssembly Beyond Browsers
by Peter Reutemann 14 Nov '19

14 Nov '19

'Mozilla has been heavily invested in WebAssembly with Firefox, and today, the organization teamed up with a few others to form the new Bytecode Alliance, which aims to create "new software foundations, building on standards such as WebAssembly and WebAssembly System Interface (WASI)." Mozilla has teamed up with Intel, Red Hat, and Fastly to found the alliance, but more members are likely to join over time. The goal of the Bytecode Alliance is to create a new runtime environment and language toolchains which are secure, efficient, and modular, while also being available on as many platforms and devices as possible. The technologies being developed by the Bytecode Alliance are based on WebAssembly and WASI, which have been seen as a potential replacement for JavaScript due to more efficient code compiling, and the expanded capabilities of being able to port C and C++ code to the web. To kick things off, the founding members have already contributed a number of open-source technologies to the Bytecode Alliance, including Wasmtime, a lightweight WebAssembly runtime; Lucet, an ahead-of-time compiler; WebAssembly Micro Runtime; and Cranelift.' -- source: https://news.slashdot.org/story/19/11/13/1750234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

TPM-FAIL Vulnerabilities Impact TPM Chips In Desktops, Laptops, Servers
by Peter Reutemann 14 Nov '19

14 Nov '19

'A team of academics has disclosed today two vulnerabilities known collectively as TPM-FAIL that could allow an attacker to retrieve cryptographic keys stored inside TPMs. The first vulnerability is CVE-2019-11090 and impacts Intel's Platform Trust Technology (PTT). Intel PTT is Intel's fTPM software-based TPM solution and is widely used on servers, desktops, and laptops, being supported on all Intel CPUs released since 2013, starting with the Haswell generation. The second is CVE-2019-16863 and impacts the ST33 TPM chip made by STMicroelectronics. This chip is incredibly popular and is used on a wide array of devices ranging from networking equipment to cloud servers, being one of the few chips that received a CommonCriteria (CC) EAL 4+ classification — which implies it comes with built-in protection against side-channel attacks like the ones discovered by the research team. Unlike most TPM attacks, these ones were deemed practical. A local adversary can recover the ECDSA key from Intel fTPM in 4-20 minutes depending on the access level. We even show that these attacks can be performed remotely on fast networks, by recovering the authentication key of a virtual private network (VPN) server in 5 hou' -- source: https://it.slashdot.org/story/19/11/13/1837225 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'When you're scrolling through Facebook's app, the social network could be watching you back, in more ways than just your data, concerned users have found. Multiple people have found and reported that their iPhone cameras were turned on in the background while looking at their feed. From a report: The issue came to light with several posts on Twitter, showing that their cameras were activated behind Facebook's app as they were watching videos or looking at photos on the social network. After clicking on the video to full screen, returning it back to normal would create a bug where Facebook's mobile layout was slightly shifted to the right. With the open space on the left, you could now see the phone's camera activated in the background.

As 5G Rolls Out, Troubling New Security Flaws Emerge
by Peter Reutemann 13 Nov '19

13 Nov '19

'It's not yet prime time for 5G networks, which still face logistical and technical hurdles, but they're increasingly coming online in major cities worldwide. Which is why it's especially worrying that new 5G vulnerabilities are being discovered almost by the dozen. From a report: At the Association for Computing Machinery's Conference on Computer and Communications Security in London today researchers are presenting new findings that the 5G specification still has vulnerabilities. And with 5G increasingly becoming a reality, time is running out to catch these flaws. The researchers from Purdue University and the University of Iowa are detailing 11 new design issues in 5G protocols that could expose your location, downgrade your service to old mobile data networks, run up your wireless bills, or even track when you make calls, text, or browse the web. They also found five additional 5G vulnerabilities that carried over from 3G and 4G. They identified all of those flaws with a new custom tool called 5GReasoner. One purported benefit of 5G is that it protects phone identifiers, like your device's "international mobile subscriber identity," to help prevent tracking or targeted attacks. But downgrade attacks like the ones the researchers found can bump your device down to 4G, or put it into limited service mode, then force it to send its IMSI number unencrypted. Increasingly, networks use an alternative ID called a Temporary Mobile Subscriber Identity that refreshes periodically to stymie tracking. But the researchers also found flaws that could allow them to override TMSI resets, or correlate a device's old and new TMSI, to track devices. Mounting those attacks takes only software-defined radios that cost a few hundred dollars. The 5GReasoner tool also found issues with the part of the 5G standard that governs things like initial device registration, deregistration, and paging, which notifies your phone about incoming calls and texts. Depending on how a carrier implements the standard, attackers could mount "replay" attacks to run up a target's mobile bill by repeatedly sending the same message or command. It's an instance of vague wording in the 5G standard that could cause carriers to implement it weakly.' -- source: https://tech.slashdot.org/story/19/11/12/1845229 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel's Cascade Lake CPUs Impacted By New Zombieload v2 Attack
by Peter Reutemann 13 Nov '19

13 Nov '19

'The Zombieload vulnerability disclosed earlier this year in May has a second variant that also works against more recent Intel processors, not just older ones, including Cascade Lake, Intel's latest line of high-end CPUs -- initially thought to have been unaffected. From a report: Intel is releasing microcode (CPU firmware) updates today to address this new Zombieload attack variant, as part of its monthly Patch Tuesday -- known as the Intel Platform Update (IPU) process. Back in May, two teams of academics disclosed a new batch of vulnerabilities that impacted Intel CPUs. Collectively known as MDS attacks, these are security flaws in the same class as Meltdown, Spectre, and Foreshadow. The attacks rely on taking advantage of the speculative execution process, which is an optimization technique that Intel added to its CPUs to improve data processing speeds and performance. Vulnerabilities like Meltdown, Spectre, and Foreshadow, showed that the speculative execution process was riddled with security holes. Disclosed in May, MDS attacks were just the latest line of vulnerabilities impacting speculative execution. They were different from the original Meltdown, Spectre, and Foreshadow bugs disclosed in 2018 because they attacked different areas of a CPU's speculative execution process.' -- source: https://hardware.slashdot.org/story/19/11/12/1924232 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Reactions To the News That Microsoft's Edge Browser Is Coming to Linux
by Peter Reutemann 11 Nov '19

11 Nov '19

'"Microsoft is bringing Edge to Linux, for all the Microsoft fans running Linux," jokes the headline at the Inquirer. ("We can just imagine the amount of bunting and party poppers that the Linux community has just ordered. After all, why wouldn't you want a browser from the company that you joined Linux to get away from?") And the headline at Liliputting quips that the Edge browser "is coming to Linux (whether you want it or not)," calling the move "the latest evidence that Microsoft's relationship to Linux has changed a lot in recent years. But TechRadar had an even more sardonic headline. "Hell freezes over as Microsoft Edge comes to Linux." One other thing to consider is that the introduction of Edge to Linux is something of a thorny subject in that the folks who choose a Linux distro often do so to break away from the chains of Microsoft and Windows (or indeed Apple). So certainly some of the more fervent open source types out there may not welcome a Microsoft browser with open arms, and doubtless it will be regarded with suspicion in some quarters. No matter how much Microsoft has been banging the open source drum in many different ways in recent times. That said, there will doubtless be Linux users who are curious, and may want to pick up a mainstream alternative to Firefox on Linux which, when compared to Chrome -- with its famous memory hogging antics -- makes a far preferable choice in some respects. Edge will also do streaming better (by default Chrome limits you to 720p when you're trying to watch a spot of Netflix). All the testing feedback about Edge has been pretty positive in the main thus far, too, so maybe that will persuade even doubters to at least consider it. One thing's for sure: it will certainly be interesting to see the reaction Microsoft's browser gets when it is deployed to Linux. Edge may face a rocky reception. "I am not feeling a tingling all over at the thought of Edge coming to Linux," posted one commenter on Beta News. "It's not really necessary to bring Linux down to the level of Windows 10."' -- source: https://linux.slashdot.org/story/19/11/11/0249222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

uBlock on Firefox 70.0.1 - memory hungry?
by Peter Reutemann 11 Nov '19

11 Nov '19

Hi everyone Since the last Firefox update to 70.0.1, I noticed that my Firefox was getting sluggish, sometimes taking several seconds before finishing rendering a page and allowing me to click on links. After looking in the processes, turns out that WebExtensions was gobbling up nearly 21GB, not to mention several other processes for rendering the tabs! It was probably swapping memory all the time... After turning off my uBlock addon (and restarting the browser, of course), Firefox is now as responsive as I was used to and WebExtensions is now ~2.5GB. Not sure whether this is due to the newly introduced privacy protection facility within core Firefox, that uBlock ballooned/slowed down like that. Anyway, still got my NoScript and PrivacyBadger addons active.

Are Forced Subscriptions Driving 3D Users To Open Source Tools?
by Peter Reutemann 11 Nov '19

11 Nov '19

'Slashdot reader dryriver writes: More and more professional 3D software like 3DMax, Maya, AutoCAD (Autodesk) and Substance Painter (Adobe) is now only available on a monthly or yearly subscription basis — you cannot buy any kind of perpetual license for these industry standard 3D tools anymore, cannot offline install or activate the tools, and the tools also phone home every few days over the internet to see whether you have "paid your rent". Stop paying your rent, and the software shuts down, leaving you unable to even look at any 3D project files you may have created with software. This has caused so much frustration, concern and anxiety among 3D content creators that, increasingly, everybody is trying to replace their commercial 3D software with Open Source 3D tools. Thankfully, open source 3D tools have grown up nicely in recent years. Some of the most popular FOSS 3D tools are the complete 3D suite Blender, polygon modeling tool Wings 3D, polygon modeling tool Dust3D, CAD modeling tool FreeCAD, PBR texturing tool ArmorPaint, procedural materials generator Material Maker, image editing tool GIMP, painting tool Krita, vector illustration tool Inkscape and the 2D/3D game engine Godot Engine. Along with these tools comes a beguiling possibility — while working with commercial 3D tools pretty much forced you to use Windows X in terms of OS choice in the past, all of the FOSS 3D tool alternatives have Linux versions. This means that for the first time, professional 3D users can give Windows a miss and work with Linux as their OS instead. In a comment on the original submission, dryriver offers some anecdotal evidence: Go on any major 3D software forum on the Internet and it is filled with enraged 3D users revolting against forced software subscriptions and threatening to switch to FOSS Blender as soon as possible. Some major 3D animation studios are also working Blender into their CGI pipeline. Companies like EPIC and Nvidia have begun donating to the Blender foundation. Its happening. The move away from commercial closed source tools - which are expensive, stagnant and don't offer you permanent licenses anymore - is in full swing. The fact that Blender has an innovative GPU accelerated realtime render engine called EEVEE that none of the commercial software has has only accelerated this trend. Blender is widely believed to have 2 - 3 million active users already, and the fact that V 2.80 comes with a much more usable UI is only accelerating things.' -- source: https://news.slashdot.org/story/19/11/09/064248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

DNS-over-HTTPS Will Eventually Roll Out in All Major Browsers, Despite ISP Opposition
by Peter Reutemann 09 Nov '19

09 Nov '19

' All major browsers -- including Chrome, Firefox, Safari, Opera, Microsoft Edge, Vivaldi, Brave -- have plans to support DNS-over-HTTPS (or DoH), a protocol that encrypts DNS traffic and helps improve a user's privacy on the web. From a report: The DoH protocol has been one of the year's hot topics. It's a protocol that, when deployed inside a browser, it allows the browser to hide DNS requests and responses inside regular-looking HTTPS traffic. Doing this makes a user's DNS traffic invisible to third-party network observers, such as ISPs. But while users love DoH and have deemed it a privacy boon, ISPs, networking operators, and cyber-security vendors hate it. A UK ISP called Mozilla an "internet villain" for its plans to roll out DoH, and a Comcast-backed lobby group has been caught preparing a misleading document about DoH that they were planning to present to US lawmakers in the hopes of preventing DoH's broader rollout. However, this may be a little too late. ZDNet has spent the week reaching out to major web browser providers to gauge their future plans regarding DoH, and all vendors plan to ship it, in one form or another.' -- source: https://it.slashdot.org/story/19/11/08/189243 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GitLab Director Resigns, Says It's Engaging In 'Retaliatory Behavior'
by Peter Reutemann 09 Nov '19

09 Nov '19

'Candice Ciresi, GitLab's director of risk and global compliance, has resigned after less than six months on the job, apparently saying that the $2.75 billion startup is "engaging in discriminatory and retaliatory behavior." Business Insider reports: Notably, Ciresi resigned in public: GitLab espouses a culture of transparency, whereby all major product and corporate policy decisions are announced and discussed where anybody can see. She posted her resignation in response to one such discussion -- an active debate over a proposed GitLab policy, in which it would ban the hiring of people who live in China or Russia for any role that would require access to customer data. At the time of writing, Ciresi's post announcing her resignation had been reviewed and then "redacted" by GitLab, citing concerns that it would "further inflame this situation." However, Ciresi's comment went out via email to GitLab users who had subscribed to this particular discussion. Per a screenshot posted to Reddit, Ciresi wrote: "As I believe GitLab is engaging in discriminatory and retaliatory behavior, I have tendered my resignation." "We did decide to moderate this post for review, as there have already been credible personal and physical threats against GitLab employees in this issue thread," GitLab says, in part, in place of Ciresi's comment. "While this particular post did not contain a personal threat to anyone, we were concerned it would further inflame this situation."

Chrome OS 78 Rolling Out With Picture-In-Picture Support For YouTube, Split Browser/Device Settings, More
by Peter Reutemann 08 Nov '19

08 Nov '19

'The latest version of Chrome OS, version 78, adds separate browser and device settings, click-to-call, and picture-in-picture support for YouTube. It also introduces virtual desktop support for the operating system with a feature called Virtual Desks. 9to5Google reports: Chrome is getting another cross-device sharing feature after "Send this page" widely rolled in September. With "click-to-call," you can right-click on phone number links -- like tel:800-800-8000 -- to have them sent to your Android device. It's quicker than manually entering those digits or transferring via email. Chrome OS 78 will separate browser and device settings. The former is accessible directly at chrome://settings and what opens when clicking "Settings" at the bottom of the Overflow menu in the top-right corner of any browser window. It opens as a tab and provides web-related preferences. Meanwhile, chrome://os-settings opens as its own window, and can be accessed from the quick settings sheet. It provides device options like Wi-Fi, Bluetooth, and Assistant in a white Material Theme UI with an icon in the launcher/app shelf. YouTube for Android now supports picture-in-picture with Chrome OS 78. After starting a video in the mobile client, switching to another window, covering, or minimizing the app will automatically open a PiP in the bottom-right corner. Available controls include switching to audio, play/pause, and skipping to the next track. In the top-left, you can expand the window and a settings gear on the other side allows you to open system settings. Tapping in the center expands and returns you to the YouTube Android app. Chrome OS 78 simplifies the printing experience by automatically listing compatible printers without any prior setup required. There are also a number of Linux on Chrome OS enhancements in this version: - Backups of Linux apps and files can now be saved to local storage, external drive, or Google Drive. That copy can be then restored when setting up a new computer. - Crostini GPU support will be enabled by default for a "crisp, lower-latency experience." - You'll be warned when using a Linux app that does not support virtual keyboard in tablet mode.' -- source: https://linux.slashdot.org/story/19/11/07/2341228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Amazon Ring Doorbells Exposed Home Wi-Fi Passwords To Hackers
by Peter Reutemann 08 Nov '19

'Security researchers have discovered a vulnerability in Ring doorbells that exposed the passwords for the Wi-Fi networks to which they were connected. Bitdefender said the Amazon-owned doorbell was sending owners' Wi-Fi passwords in cleartext as the doorbell joins the local network, allowing nearby hackers to intercept the Wi-Fi password and gain access to the network to launch larger attacks or conduct surveillance. "When first configuring the device, the smartphone app must send the wireless network credentials. This takes place in an unsecure manner, through an unprotected access point," said Bitdefender. "Once this network is up, the app connects to it automatically, queries the device, then sends the credentials to the local network." But all of this is carried out over an unencrypted connection, exposing the Wi-Fi password that is sent over the air. Amazon fixed the vulnerability in all Ring devices in September, but the vulnerability was only disclosed today.' -- source: https://mobile.slashdot.org/story/19/11/07/2125208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft’s Project Silica offers robust thousand-year storage
by Peter Reutemann 08 Nov '19

08 Nov '19

Not strictly Linux or open source related, but I wouldn't mind having a backup that lasts longer than just a few years! 'Ars spoke Tuesday with Dr. Ant Rowstron, a principal researcher at Microsoft Research in Cambridge, UK, about an innovative cold storage project called Silica. Silica aims to replace both tape and optical archival discs as the media of choice for large-scale, (very) long duration cold storage. Microsoft Research is partnering with film giant Warner Bros., which is directly interested in reducing costs and increasing reliability in its own cold storage programs. The medium in question is a block of high-purity glass, which has voxels etched into it with femtosecond lasers. Each voxel stores multiple bits in two properties, retardance and angle, which may in turn be read using microscope imaging and polarized light. Voxels may be written 100 or more layers deep in a 2mm-deep piece of glass, by focusing the laser to the desired depth within the block itself. The speed of both reads and writes to Silica currently leave something to be desired—it took approximately a week to etch Superman's roughly 76GB of data last year, and Rowstron estimates it would take about three days to re-read the data, with advances made since. The technology is still in its infancy, of course, and large decreases in time required for both writing and reading are expected moving forward. Rowstron says he still doesn't expect anyone is likely to try to actually play Superman directly from its Silica record—but that's not what it's intended for.' -- source: https://arstechnica.com/gadgets/2019/11/microsofts-project-silica-offers-ro… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Original Google Pixel Will Get One Final Update In December
by Peter Reutemann 06 Nov '19

'Google has confirmed to The Verge that it will release "one final software update" next month for the original Google Pixel and Pixel XL. From the report: As of yesterday, it looked like the original Pixel was done getting updates, as Google released its November security update for most Pixel phones, but nothing for the Pixel or Pixel XL. Google tells The Verge that the Pixels won't get that November update, but it says December's "encapsulates a variety of updates" from the November and December updates that were issued for other Pixels. It wasn't too surprising to see that Google's original Pixels didn't get yesterday's update. When Google announced the phones in 2016, the company said they would get two years of guaranteed Android version updates and three years of security updates, which is also reflected on Google's support page. That said, Google surprised Pixel owners earlier this year by letting them run Android 10, which is one more year of Android than Google originally promised, and now, they have one final update to look forward to as well.

Android Bug Lets Hackers Plant Malware Via NFC Beaming
by Peter Reutemann 05 Nov '19

05 Nov '19

'Google patched last month an Android bug that can let hackers spread malware to a nearby phone via a little-known Android OS feature called NFC beaming. NFC beaming works via an internal Android OS service known as Android Beam. This service allows an Android device to send data such as images, files, videos, or even apps, to another nearby device using NFC (Near-Field Communication) radio waves, as an alternative to WiFi or Bluetooth. Typically, apps (APK files) sent via NFC beaming are stored on disk and a notification is shown on screen. The notification asks the device owner if he wants to allow the NFC service to install an app from an unknown source. But, in January this year, a security researcher named Y. Shafranovich discovered that apps sent via NFC beaming on Android 8 (Oreo) or later versions would not show this prompt. Instead, the notification would allow the user to install the app with one tap, without any security warning. The CVE-2019-2114 bug resided in the fact that the Android Beam app was also whitelisted, receiving the same level of trust as the official Play Store app. Google said this wasn't meant to happen, as the Android Beam service was never meant as a way to install applications, but merely as a way to transfer data from device to device. The October 2019 Android patches removed the Android Beam service from the OS whitelist of trusted sources. However, many millions of users remain at risk. If users have the NFC service and the Android Beam service enabled, a nearby attacker could plant malware (malicious apps) on their phones. Since most newly-sold devices have the NFC feature enabled by default, you'll have to disable Android Beam and NFC or update your phone to receive the October 2019 security updates if you want to protect yourself from this bug.' -- source: https://it.slashdot.org/story/19/11/04/216228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Researchers hack Siri, Alexa, and Google Home by shining lasers at them
by Peter Reutemann 05 Nov '19

05 Nov '19

'Siri, Alexa, and Google Assistant are vulnerable to attacks that use lasers to inject inaudible—and sometimes invisible—commands into the devices and surreptitiously cause them to unlock doors, visit websites, and locate, unlock, and start vehicles, researchers report in a research paper published on Monday. Dubbed Light Commands, the attack works against Facebook Portal and a variety of phones. Shining a low-powered laser into these voice-activated systems allows attackers to inject commands of their choice from as far away as 360 feet (110m). Because voice-controlled systems often don’t require users to authenticate themselves, the attack can frequently be carried out without the need of a password or PIN. Even when the systems require authentication for certain actions, it may be feasible to brute force the PIN, since many devices don’t limit the number of guesses a user can make. Among other things, light-based commands can be sent from one building to another and penetrate glass when a vulnerable device is kept near a closed window. The attack exploits a vulnerability in microphones that use micro-electro-mechanical systems, or MEMS. The microscopic MEMS components of these microphones unintentionally respond to light as if it were sound. While the researchers tested only Siri, Alexa, Google Assistant, Facebook Portal, and a small number of tablets and phones, the researchers believe all devices that use MEMS microphones are susceptible to Light Commands attacks.' -- source: https://arstechnica.com/information-technology/2019/11/researchers-hack-sir… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Linus Torvalds: 'I'm Not a Programmer Anymore'

'Linus Torvalds, Linux's creator, doesn't make speeches anymore. But, what he does do, and he did again at Open Source Summit Europe in Lyon France is have public conversations with his friend Dirk Hohndel, VMware's Chief Open Source Officer. In this keynote discussion, Torvalds revealed that he doesn't think he's a programmer anymore. So what does the person everyone thinks of as a programmer's programmer do instead? Torvalds explained: "I don't know coding at all anymore. Most of the code I write is in my e-mails. So somebody sends me a patch ... I [reply with] pseudo code. I'm so used to editing patches now I sometimes edit patches and send out the patch without having ever tested it. I literally wrote it in the mail and say, 'I think this is how it should be done,' but this is what I do, I am not a programmer." So, Hohndel asked, "What is your job?" Torvalds replied, "I read and write a lot of email. My job really is, in the end, is to say 'no.' Somebody has to say 'no' to [this patch or that pull request]. And because developers know that if they do something that I'll say 'no' to, they do a better job of writing the code."' -- source: https://linux.slashdot.org/story/19/11/03/2230223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'In a move to fight spam and improve the health of the web, Firefox will hide those annoying notification popups by default starting next year, with the release of Firefox 72, in January 2020, ZDNet has learned from a Mozilla engineer. The move comes after Mozilla ran an experiment back in April this year to see how users interacted with notifications, and also looked at different ways of blocking notifications from being too intrusive. Usage stats showed that the vast majority (97%) of Firefox users dismissed notifications, or chose to block a website from showing notifications at all... As a result, Mozilla engineers have decided to hide the notification popup that drops down from Firefox's URL bar, starting with Firefox 72. If a website shows a notification, the popup will be hidden by default, and an icon added to the URL bar instead. Firefox will then animate the icon using a wiggle effect to let the user know there's a notification subscription popup available, but the popup won't be displayed until the user clicks the icon. Mozilla is the first browser vendor to block notification popups by default, according to the article. It's already available in Firefox Nightly versions, but will be added to the stable branch in January. "I think Mozilla's decision is good for the health of the web," Jérôme Segura, malware analyst at Malwarebytes tells ZDNet.' -- source: https://news.slashdot.org/story/19/11/03/1646236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Does Linux Have a Marketing Problem?
by Peter Reutemann 04 Nov '19

04 Nov '19

'On Hackaday's hosting site Hackaday.io, an electrical engineer with a background in semiconductor physics argues that Linux's small market share is due to a lack of marketing: Not only does [Linux] have dominance when raw computing ability is needed, either in a supercomputer or a webserver, but it must have some ability to effectively work as a personal computer as well, otherwise Android wouldn't be so popular on smartphones and tablets. >From there it follows that the only reason that Microsoft and Apple dominate the desktop world is because they have a marketing group behind their products, which provides customers with a comfortable customer service layer between themselves and the engineers and programmers at those companies, and also drowns out the message that Linux even exists in the personal computing realm... Part of the problem too is that Linux and most of its associated software is free and open source. What is often a strength when it comes to the quality of software and its flexibility and customizablity becomes a weakness when there's no revenue coming in to actually fund a marketing group that would be able to address this core communications issue between potential future users and the creators of the software. Canonical, Red Hat, SUSE and others all had varying successes, but this illistrates another problem: the splintered nature of open-source software causes a fragmenting not just in the software itself but the resources. Imagine if there were hundreds of different versions of macOS that all Apple users had to learn about and then decide which one was the best for their needs... I have been using Linux exclusively since I ditched XP for 5.10 Breezy Badger and would love to live in a world where I'm not forced into the corporate hellscape of a Windows environment every day for no other reason than most people already know how to use Windows. With a cohesive marketing strategy, I think this could become a reality, but it won't happen through passionate essays on "free as in freedom" or the proper way to pronounce "GNU" or the benefits of using Gentoo instead of Arch. It'll only come if someone can unify all the splintered groups around a cohesive, simple message and market it to the public.' -- source: https://linux.slashdot.org/story/19/11/03/2012226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Incognito Mode For Google Maps Arrives On Android
by Peter Reutemann 01 Nov '19

01 Nov '19

'Incognito Mode for Google Maps is rolling out to Android users to prevent your search queries and real-time tracked location from being recorded onto your Google account. Engadget reports: It's not something you'll want to use all the time as some features will be disabled, and it's important to note that it doesn't turn off all tracking. The places you go won't be saved to your Location History (if you have that enabled), your searches won't be saved to your account and it won't use your information to personalize the experience. Still, you could be tracked by internet service providers, other apps, or if you're using Assistant and other Google services. Similar to incognito on Chrome, it's more useful as a depersonalized look at recommendations than as a full-fledged privacy protector, and a way to make sure that whatever you're searching for in this instance doesn't affect your recommendations later -- don't worry, we're not judging.

Google's Network Congestion Algorithm Isn't Fair, Researchers Say
by Peter Reutemann 01 Nov '19

01 Nov '19

'Researchers at Carnegie Mellon University say a Google algorithm designed help reduce internet congestion is mathematically unfair, resulting in network management systems that may disadvantage some traffic over others. From a report: Several years back, Google began work on a new open source congestion control algorithm (CCA) designed to improve the way the internet functions. The result was BBR, short for Bottleneck Bandwidth and RTT (Round-Trip Time). The goal of the project: to improve how network packets travel between servers to mitigate congestion on the internet. CCAs have long been used to help manage congestion -- ideally while treating all traffic equally. But in a study unveiled last week at the Internet Measurement Conference in Amsterdam, researchers revealed that BBR doesn't actually do a very good job of that last part. In fact, they found that during periods of congestion, BBR connections would take up 40 percent of the available bandwidth, leaving the remaining 60 percent to be fought over by the remaining users on the network.' -- source: https://tech.slashdot.org/story/19/10/31/204226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Text Editor Releases 'Free Uyghur' Edition, Gets Swamped With Chinese Spam
by Peter Reutemann 01 Nov '19

01 Nov '19

Something from the Windows open-source camp rather than Linux: 'This week, the developer of the popular text- and code-editing software Notepad++ released a new version update. Nothing seemed particularly strange about it, except maybe the name: Notepad++ v7.8.1 is the "Free Uyghur" edition. In a blog post announcing the updated version, developer Don Ho writes about the plight of the Uyghur people, an ethnic minority in China that's faced persecution from the country's authoritarian government. China operates internment camps that are used to detain Uyghur people throughout the country's Xinjiang region. Since the announcement, the software's GitHub "issues" page has been bombarded with spam, much of it in the Chinese language. "Stop sending meaningless political-related issues, it just makes you look like an idiot," reads one comment. Another one simply reads, "Bye ! Uninstall." There's a litany of curses, and one asks, "What do you know about China?" Others have moved in to criticize the Chinese government in response. Ho told The Verge that the software's dedicated site was also under a distributed-denial-of-service attack, but that it has been stopped by an anti-DDoS service provided by the site's host. Ho writes in the announcement that he anticipated potential pushback, saying "talking about politics is exactly what software and commercial companies generally try to avoid," but decided to take the step anyway. "The problem is," Ho writes in the announcement of the Free Uyghur edition, "if we don't deal with politics, politics will deal with us.' -- source: https://tech.slashdot.org/story/19/10/31/0037247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Fedora 31 Released
by Peter Reutemann 01 Nov '19

01 Nov '19

'Fedora 31 has just rolled out the door. From a report: Is it an exciting release? No, not really. Sure, enthusiasts will find themselves thrilled withe inclusion of the GNOME 3.34 desktop environment (with Qt Wayland by default), Linux 5.3 kernel, and Mesa 9.2, but otherwise, it is fairly boring. You know what? That's not a bad thing. In 2019, Fedora is simply a mature and stable operating system that only needs to follow an evolutionary path at this time -- not revolutionary. It stands alone as the world's best desktop Linux distribution. "Fedora 31 Workstation provides new tools and features for general users as well as developers with the inclusion of GNOME 3.34. GNOME 3.34 brings significant performance enhancements which will be especially noticeable on lower-powered hardware. Fedora 31 Workstation also expands the default uses of Wayland, including allowing Firefox to run natively on Wayland under GNOME instead of the XWayland backend as with prior releases," says The Fedora Project.' -- sources: https://linux.slashdot.org/story/19/10/31/168259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New 'Unremovable' XHelper Malware Has Infected 45,000 Android Devices
by Peter Reutemann 30 Oct '19

30 Oct '19

'Over the past six months, a new Android malware strain has made a name for itself after popping up on the radar of several antivirus companies, and annoying users thanks to a self-reinstall mechanism that has made it near impossible to remove. Named xHelper, this malware was first spotted back in March but slowly expanded to infect more than 32,000 devices by August (per Malwarebytes), eventually reaching a total of 45,000 infections this month (per Symantec). The malware is on a clear upward trajectory. Symantec says the xHelper crew is making on average 131 new victims per day and around 2,400 new victims per month. Most of these infections have been spotted in India, the U.S., and Russia. According to Malwarebytes, the source of these infections is "web redirects" that send users to web pages hosting Android apps. These sites instruct users on how to side-load unofficial Android apps from outside the Play Store. Code hidden in these apps downloads the xHelper trojan. The good news is that the trojan doesn't carry out destructive operations. According to both Malwarebytes and Symantec, for most of its operational lifespan, the trojan has shown intrusive popup ads and notification spam. The ads and notifications redirect users to the Play Store, where victims are asked to install other apps -- a means through which the xHelper gang is making money from pay-per-install commissions. What's interesting about xHelper is that it gains access to an Android device via an initial app and installs itself as a separate self-standing service. Furthermore, you can't remove the app, as the trojan reinstalls itself every time, even after users perform a factory reset.' -- source: https://tech.slashdot.org/story/19/10/29/2121244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How a months-old AMD microcode bug destroyed my weekend [UPDATED]
by Peter Reutemann 30 Oct '19

30 Oct '19

'This weekend, I was excited to deploy my first Ryzen 3000-powered workstation in my home office. Unfortunately, a microcode bug—originally discovered in July but still floating around in large numbers in the wild—wrecked my good time. I eventually got my Ryzen 3700X system working, and it's definitely fast. But unfortunately, it's still bugged, and there's no easy way to fix it. Not long after the product launch, AMD Ryzen 3000 customers started noticing problems with their shiny new CPUs. Windows users couldn't successfully launch Destiny 2 (due to a power-management bug, unrelated to the one sidelining my system), and Linux users in many cases couldn't even get their system to boot. Jason Evangelho covered the initial discovery and report of the bug at Forbes back in July, and an AMD representative provided him with a statement by email: "AMD has identified the root cause and implemented a BIOS fix for an issue impacting the ability to run certain Linux distributions and Destiny 2 on Ryzen 3000 processors. We have distributed an updated BIOS to our motherboard partners, and we expect consumers to have access to the new BIOS over the coming days." This sounds happy and upbeat, but the reality isn't quite so simple. When there's a bug in the CPU microcode, you're at the mercy of your motherboard vendor to release a new system BIOS that will update it for you—you can't just go to some download link at AMD and apply a fix yourself. AMD responded to the bug in July. As far as I can tell, AMD did so only by direct email response; there's no press release about it—and the company's response made it sound like everything would be fixed in a week or two. I have the unfortunate duty of reporting to you, three months later, that it is not.' -- source: https://arstechnica.com/gadgets/2019/10/how-a-months-old-amd-microcode-bug-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

50 Years Ago, the Internet Was Born In Room 3420
by Peter Reutemann 30 Oct '19

30 Oct '19

'On October 29, 1969, a graduate student in a UCLA computer science lab logged into a computer hundreds of miles away at the Stanford Research Institute. It was the first connection via ARPANET, which -- after 20 years as a government and academic network -- evolved into the modern internet. Over at Fast Company, Mark Sullivan marked the anniversary by visiting the room where the historic login took place and talking to three of the people who made it happen.' -- source: https://tech.slashdot.org/story/19/10/29/1557212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'The BBC has made its international news website available via the Tor network, in a bid to thwart censorship attempts. The browser can obscure who is using it and what data is being accessed, which can help people avoid government surveillance and censorship. Countries including China, Iran and Vietnam are among those who have tried to block access to the BBC News website or programs. Instead of visiting bbc.co.uk/news or bbc.com/news, users of the Tor browser can visit the new bbcnewsv2vjtpsuy.onion web address.
