GNU is Not Unix Emacs Developers (Including Richard Stallman) Discuss How to Build a More 'Modern' Emacs
by Peter Reutemann 27 Sep '20

27 Sep '20

'LWN.net re-visits the emacs-devel mailing list, where the Emacs 28 development cycle has revived discussions about how to make the text editor more "modern" and attractive to new users: A default dark theme may not be in the future, leading one to think that there may yet be hope for the world in general. But there does seem to be general agreement that Emacs could benefit from a better, more centralized approach to color themes, rather than having color names hard-coded throughout various Elisp packages. From that, a proper theme engine could be supported, making dark themes and such easily available to those who want them... Another area where Emacs is insufficiently "modern", it seems, has to do with keyboard and mouse bindings. On the keyboard side, users have come to expect certain actions from certain keystrokes; ^X to cut a selection, ^V to paste it, etc. These bindings are easily had by turning on the Cua mode, but new users tend not to know about this mode or how to enable it. Many participants in the discussion said that this mode should be on by default. That, of course, would break the finger memory of large numbers of existing Emacs users, who would be unlikely to appreciate the disruption. Or, as Richard Stallman put it: It is not an option to change these basic key bindings to imitate other, newer editors. It would create a different editor that we Emacs users would never switch to. It is unfortunate that the people who implemented the newer editors chose incompatibility with Emacs.... The situation with mouse behavior is similar; as several participants in the discussion pointed out, users of graphical interfaces have come to expect that a right-button click will produce a menu of available actions. In Emacs, instead, that button marks a region ("selection"), with a second click in the same spot yanking ("cutting") the selected text. Many experienced Emacs users have come to like this behavior, but it is surprising to newcomers. The right mouse button with the control key held down does produce a menu defined by the current major mode, but that is evidently not what is being requested here; that menu, some say, should present global actions rather mode-specific ones. Stallman suggested offering a "reshuffled mode" that would bring the context menu to an unadorned right-button click, and which would add some of the expected basic editing commands there as well. This would be relatively easy to do, he said, since mouse bindings are separate from everything else. Besides, as he noted, the current mouse behavior was derived from "what was the standard in X Windows around 1990"; while one wouldn't want to act in haste, it might just be about time for an update. Other proposed changes involved "discoverability," including the default enabling of various modes, although to incorporate them into GNU Emacs "would often require the author to sign copyrights over to the Free Software Foundation, which is not something all authors are willing to do..."' -- source: https://news.slashdot.org/story/20/09/25/2213230 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/

Bored Developer Creates 'DOS Subsystem For Linux'
by Peter Reutemann 27 Sep '20

27 Sep '20

'iTnews: A software engineer in Melbourne is whiling away the city's lockdown by creating a tool that DOS users so far have lacked: an integrated Linux environment similar to what Windows 10 users enjoy... "I first started out just seeing if I could get Linux booting from the DOS command line, and that turned out to be straightforward enough so I thought it'd be fun to see if I could continue executing DOS once Linux was running," Charlie Somerville said. "I'm mostly surprised by how smoothly the whole thing works given how *dodgy* it all is haha," he added. DOS Subsystem for Linux runs a real copy of MS-DOS under the QEMU virtual machine, and starts up from that, Somerville said... "Helpfully Linux seems to leave the first megabyte of memory (where DOS lives) intact during its own boot process, so it's just a matter of jumping back to the right place to continue DOS execution," he added. Somerville had it pointed out to him that this approach of running DOS under vm8086 is actually how early Windows worked. "Kinda cool to rediscover the technique so many years later," Somerville said.' -- source: https://linux.slashdot.org/story/20/09/26/048223 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 81 Released, Can Now Be Your Default Browser in iOS
by Peter Reutemann 27 Sep '20

27 Sep '20

'Engadget reports: One big benefit of iOS 14 is that you can set non-Apple-made apps as your default, including for email and web browsing. Hot on the heels of you being able to set Chrome and Gmail as your clients of choice, Firefox is enabling you to make its browser the default on iPhones and iPads. Naturally, you'll need to have both the latest version of the operating system and the apps, and then just make the switch inside settings. Meanwhile, Bleeping Computer profiles some of the new features in this week's release of Firefox 81, including: The ability to control videos via your headset and keyboard even if you're not using Firefox at the time - A new credit card autofill feature for Firefox users in the U.S. and Canada - A new theme called AlpenGlow - Firefox can now be set as the default system PDF viewer' -- source: https://news.slashdot.org/story/20/09/26/0454229 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/

Bug Allowed Hijacking Other Firefox Mobile Browsers on the Same Wi-Fi Network
by Peter Reutemann 27 Sep '20

27 Sep '20

'"Mozilla has fixed a bug that can be abused to hijack all the Firefox for Android browsers on the same Wi-Fi network and force users to access malicious sites, such as phishing pages," reports ZDNet: The bug was discovered by Chris Moberly, an Australian security researcher working for GitLab. The actual vulnerability resides in the Firefox SSDP component. SSDP stands for Simple Service Discovery Protocol and is the mechanism through which Firefox finds other devices on the same network in order to share or receive content (i.e., such as sharing video streams with a Roku device). When devices are found, the Firefox SSDP component gets the location of an XML file where that device's configuration is stored. However, Moberly discovered that in older versions of Firefox, you could hide Android "intent" commands in this XML and have the Firefox browser execute the "intent," which could be a regular command like telling Firefox to access a link... The bug was fixed in Firefox 79; however, many users may not be running the latest release. Firefox for desktop versions were not impacted.

Facebook “Took A Page From Big Tobacco’s Playbook”
by Lawrence D'Oliveiro 26 Sep '20

26 Sep '20

Some former Facebook employees are testifying to the US Congress <https://arstechnica.com/tech-policy/2020/09/former-facebook-manager-we-took…> as part of a hearing into the role social media platforms play in spreading extremist and radical content. Tim Kendall, former director of monetization, says: “We took a page form Big Tobacco’s playbook, working to make our offering addictive at the outset.” After making some more direct comparisons with how tobacco companies made their product more addictive, he talked about “engagement”, which was the measure Facebook tried to maximize above all else: “We initially used engagement as sort of a proxy for user benefit,” Kendall explained. “But we also started to realize that engagement could also mean [users] were sufficiently sucked in that they couldn’t work in their own best long-term interest to get off the platform... We started to see real-life consequences, but they weren’t given much weight. Engagement always won, it always trumped.” If a company becomes large and powerful, and cannot be trusted to exercise that power responsibly, then it must be taken from them.

Researchers Found the Manual For the World's Oldest Surviving Computer
by Peter Reutemann 24 Sep '20

24 Sep '20

'Researchers will be able to gain a deeper understanding of what's considered the world's oldest surviving (digital) computer after its long-lost user manual was unearthed. Engadget reports: The Z4, which was built in 1945, runs on tape, takes up most of a room and needs several people to operate it. The machine now takes residence at the Deutsches Museum in Munich, but it hasn't been used in quite some time. An archivist at ETH Zurich, Evelyn Boesch, discovered the manual among her father's documents in March, according to retired lecturer Herbert Bruderer. Rene Boesch worked with the Swiss Aeronautical Engineering Association, which was based at the university's Institute for Aircraft Statics and Aircraft Construction. The Z4 was housed there in the early 1950s. Among Boesch's documents were notes on math problems the Z4 solved that were linked to the development of the P-16 jet fighter. "These included calculations on the trajectory of rockets, on aircraft wings, on flutter vibrations [and] on nosedive," Bruderer wrote in a Association of Computing Machinery blog post.' -- source: https://hardware.slashdot.org/story/20/09/23/2058222 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/

'Federal and state officials are seeing a big uptick in infections coming from LokiBot, an open source DIY malware package for Windows that’s openly sold or traded for free in underground forums.

Firefox usage is down 85% despite Mozilla's top exec pay going up 400%
by Peter Reutemann 24 Sep '20

24 Sep '20

'Mozilla recently announced that they would be dismissing 250 people. That's a quarter of their workforce so there are some deep cuts to their work too. The victims include: the MDN docs (those are the web standards docs everyone likes better than w3schools), the Rust compiler and even some cuts to Firefox development. Like most people I want to see Mozilla do well but those three projects comprise pretty much what I think of as the whole point of Mozilla, so this news is a a big let down. The stated reason for the cuts is falling income. Mozilla largely relies on "royalties" for funding. In return for payment, Mozilla allows big technology companies to choose the default search engine in Firefox - the technology companies are ultimately paying to increase the number of searches Firefox users make with them. Mozilla haven't been particularly transparent about why these royalties are being reduced, except to blame the coronavirus. I'm sure the coronavirus is not a great help but I suspect the bigger problem is that Firefox's market share is now a tiny fraction of its previous size and so the royalties will be smaller too - fewer users, so fewer searches and therefore less money for Mozilla. The real problem is not the royalty cuts, though. Mozilla has already received more than enough money to set themselves up for financial independence. Mozilla received up to half a billion dollars a year (each year!) for many years. The real problem is that Mozilla didn't use that money to achieve financial independence and instead just spent it each year, doing the organisational equivalent of living hand-to-mouth. Despite their slightly contrived legal structure as a non-profit that owns a for-profit, Mozilla are an NGO just like any other. In this article I want to apply the traditional measures that are applied to other NGOs to Mozilla in order to show what's wrong.' -- source: http://calpaterson.com/mozilla.html 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/

Russia Wants To Ban the Use of Secure Protocols Such As TLS 1.3, DoH, DoT, ESNI

Microsoft Is Bringing Edge To Linux

Microsoft will start with the Ubuntu and Debian distributions, with support for Fedora and openSUSE coming afterwards. "Linux stands out in that, while it has a relatively small desktop population in terms of what you might call typical consumer or end user, developers are often overrepresented in that population, and especially in areas like test automation, or CI/CD workloads for their web apps," Edge program manager Kyle Pflug told VentureBeat. "Edge on Linux is a natural part of our strategy to reduce fragmentation and test overhead for web developers. By providing the same rendering behavior and tools across platforms, developers can build and test sites and web apps in their preferred environment and be confident in the experience their customers will have."' -- source: https://linux.slashdot.org/story/20/09/22/1924237 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/

Automated Unit Testing: Quis Custodiet Ipsos Custodes?
by Lawrence D'Oliveiro 22 Sep '20

22 Sep '20

A company called Diffblue has a product that uses AI techniques to automatically generate unit tests for your code <https://www.theregister.com/2020/09/21/diffblue_let_ai_code_unit_tests/>. Only problem is, it doesn’t actually know what the intent of your code is, so it assumes it is correct to begin with, and generates tests on that basis. So who tests the test code? It falls back to a human to ensure the tests make sense. But doesn’t that defeat the point of having them done automatically? Unless you only use the system to catch regressions--things that were previously working, but get broken by newer changes to the code. Even then, it seems to me there is a likelihood of false positives, caused by refactoring of functionality between different modules; too many of these, and the humans are going to start ignoring the test results.

GNOME Gets New Versioning Scheme
by Peter Reutemann 22 Sep '20

22 Sep '20

'The GNOME 3 desktop environment was officially released in 2011, and in 2020 we are still on version 3.x. Yeah, despite many massive changes over the last (almost) decade, we have been stuck with point releases for GNOME 3. For instance, just last week, GNOME 3.38 was released. Historically, the stable releases all ended in even numbers, with pre-release versions ending in odd. For fans of the DE, such as yours truly, we have simply learned to live with this odd versioning scheme. Well, folks, with the next version of GNOME, the developers have finally decided to move on from version 3.x. You are probably thinking the new version will be 4.0, but you'd be very wrong. Actually, following GNOME3.38 will be GNOME 40. "After nearly 10 years of 3.x releases, the minor version number is getting unwieldy. It is also exceedingly clear that we're not going to bump the major version because of technological changes in the core platform, like we did for GNOME 2 and 3, and then piling on a major UX change on top of that. Radical technological and design changes are too disruptive for maintainers, users, and developers; we have become pretty good at iterating design and technologies, to the point that the current GNOME platform, UI, and UX are fairly different from what was released with GNOME 3.0, while still following the same design tenets," says Emmanuele Bassi, The GNOME Foundation.' -- source: https://linux.slashdot.org/story/20/09/21/1652221 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/

Could Open Source Licensing Stop Big Pharma Profiteering On Taxpayer-Funded Covid-19 Vaccines?
by Peter Reutemann 21 Sep '20

21 Sep '20

'Two professors at the University of Massachusetts have co-authored a new essay explaining how open source licensing "could keep Big Pharma from making huge profits off taxpayer-funded research" in the international, multi-billion-dollar race for a Covid-19 vaccine: The invention of the "General Public License," sometimes referred to as a viral or reciprocal license, meant that should an improvement be made, the new software version automatically inherits the same license as its parent. We believe that in a time of a global pandemic, a safe and effective COVID-19 vaccine should be licensed with General Public License-like properties... Fortunately, some pharmaceutical companies, national governments, nonprofits like the Bill & Melinda Gates Foundation and international organizations like the Coalition for Epidemic Preparedness Initiatives — which supports vaccine development — are putting policies in place that embrace openness and sharing rather than intellectual property protection. Coalition for Epidemic Preparedness Initiatives officials have stated that all of their funding agreements require that "appropriate vaccines are first available to populations when and where they are needed to end an outbreak or curtail an epidemic, regardless of ability to pay." That's an important start. However, when there is a safe, effective COVID-19 vaccine, the U.S. and other national governments need to create contractual agreements with firms that provide fair and reasonable funding to cover their costs or even some reasonable profit margin while still mandating the open sharing of the processes for vaccine production, quality assurance and rapid global distribution.' -- source: https://science.slashdot.org/story/20/09/20/2359229 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/

DuckDuckGo saw over 2 billion searches and 4 million app/extension installations, and the company also said that they have over 65 million active users. DuckDuckGo could shatter its old traffic record if the same growth trend continues.

From a report: Mozilla on Thursday announced a project that asks people to download a software tool that gives Mozilla's researchers information on what video recommendations people are receiving on the Google-owned platform. YouTube's algorithms recommend videos in the "What's next" column along the right side of the screen, inside the video player after the content has ended, or on the site's homepage. Each recommendation is tailored to the person watching, taking into account things like their watch history, list of channel subscriptions or location. The recommendations can be benign, like another live performance from the band you're watching. But critics say YouTube's recommendations can also lead viewers to fringe content, like medical misinformation or conspiracy theories.

Cloudflare and the Wayback Machine, Joining Forces For a More Reliable Web
by Peter Reutemann 18 Sep '20

18 Sep '20

'Cloudflare and the Internet Archive are now working together to help make the web more reliable. Websites that enable Cloudflare's Always Online service will now have their content automatically archived, and if by chance the original host is not available to Cloudflare, then the Internet Archive will step in to make sure the pages get through to users. From a report: Cloudflare has become core infrastructure for the Web, and we are glad we can be helpful in making a more reliable web for everyone."The Internet Archive's Wayback Machine has an impressive infrastructure that can archive the web at scale," said Matthew Prince, co-founder and CEO of Cloudflare. "By working together, we can take another step toward making the Internet more resilient by stopping server issues for our customers and in turn from interrupting businesses and users online." For more than 20 years the Internet Archive's Wayback Machine has been archiving much of the public Web, and making those archives available to journalists, researchers, activists, academics and the general public, in total to hundreds of thousands of people a day. To date more than 468 billion Web pages are available via the Wayback Machine and we are adding more than 1 billion new archived URLs/day. We archive URLs that are identified via a variety of different methods, such as "crawling" from lists of millions of sites, as submitted by users via the Wayback Machine's "Save Page Now" feature, added to Wikipedia articles, referenced in Tweets, and based on a number of other "signals" and sources, such multiple feeds of "news" stories. An additional source of URLs we will preserve now originates from customers of Cloudflare's Always Online service. As new URLs are added to sites that use that service they are submitted for archiving to the Wayback Machine. In some cases this will be the first time a URL will be seen by our system and result in a "First Archive" event.' -- source: https://tech.slashdot.org/story/20/09/17/1544222 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 Shuts Down Firefox Send and Firefox Notes Services
by Peter Reutemann 18 Sep '20

18 Sep '20

'Mozilla is shutting down two of its legacy products, Firefox Send and Firefox Notes, the company announced today. From a report: "Both services are being decommissioned and will no longer be a part of our product family," a Mozilla spokesperson told ZDNet this week. Of the two, the most beloved was Firefox Send, a free file-sharing service, and one of the few that supported sharing files in encrypted formats. Launched in March 2019, the service gained a dedicated fanbase but Send was taken offline earlier this summer after ZDNet reported on its constant abuse by malware groups. At the time, Mozilla said that Send's shutdown was temporary and promised to find a way to curb the service's abuse in malware operations. But weeks later, things changed after Mozilla leadership laid off more than 250 employees as part of an effort to re-focus its business on commercial products.' -- source: https://tech.slashdot.org/story/20/09/17/1923240 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/

Billions of Devices Vulnerable To New 'BLESA' Bluetooth Spoofing Attack
by Peter Reutemann 17 Sep '20

17 Sep '20

'"Billions of smartphones, tablets, laptops, and IoT devices are using Bluetooth software stacks that are vulnerable to a new security flaw disclosed over the summer," reports ZDNet. Named BLESA (Bluetooth Low Energy Spoofing Attack), the vulnerability impacts devices running the Bluetooth Low Energy (BLE) protocol, and affects the reconnection process that occurs when a device moves back into range after losing or dropping its pairing. A successful BLESA attack allows bad actors to connect with a device (by getting around reconnection authentication requirements) and send spoofed data to it. In the case of IoT devices, those malicious packets can convince machines to carry out different or new behavior. For humans, attackers could feed a device deceptive information. BLESA impacts billions of devices that run vulnerable BLE software stacks. Vulnerable are BLE software libraries like BlueZ (Linux-based IoT devices), Fluoride (Android), and the iOS BLE stack. Windows' BLE stack is not impacted.' -- source: https://it.slashdot.org/story/20/09/16/220211 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 Submits Linux Kernel Patches For a 'Complete Virtualization Stack' With Linux and Hyper-V
by Peter Reutemann 16 Sep '20

16 Sep '20

'Microsoft has submitted a series of patches to the Linux kernel with its aim being "to create a complete virtualization stack with Linux and Microsoft Hypervisor." The Register reports: The patches are designated "RFC" (Request for comments) and are a minimal implementation presented for discussion. The key change is that with the patched kernel, Linux will run as the Hyper-V root partition. In the Hyper-V architecture, the root partition has direct access to hardware and creates child partitions for the VMs it hosts. "Just think of it like Xen's Dom0," said Microsoft principal software engineer Wei Liu. Hyper-V's architecture is more similar to Xen than it is to KVM or to VMware's ESXi, and Liu acknowledged that "we drew inspiration from the Xen code in Linux," specifically for code handing interrupts. Until now, the Hyper-V root partition had to run Windows. Microsoft has also ported Intel's open-source Cloud Hypervisor, a Virtual Machine Monitor (VMM) written in Rust that normally runs on KVM, the hypervisor that is built into the Linux kernel. Cloud Hypervisor itself is currently in "very early pre-alpha stage." Even when Linux is the root partition, it will still run on top of Microsoft's hypervisor, a thin layer running with ring -1 privileges. It will no longer be necessary to run Windows on that hypervisor, though, enabling Microsoft to call the new arrangement "a complete virtualization stack with Linux."' -- source: https://linux.slashdot.org/story/20/09/15/207219 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 Police Malware Could Harvest GPS, Messages, Passwords, More
by Peter Reutemann 16 Sep '20

16 Sep '20

'The malware that French law enforcement deployed en masse onto Encrochat devices, a large encrypted phone network using Android phones, had the capability to harvest "all data stored within the device," and was expected to include chat messages, geolocation data, usernames, passwords, and more, according to a document obtained by Motherboard. From the report: The document adds more specifics around the law enforcement hack and subsequent takedown of Encrochat earlier this year. Organized crime groups across Europe and the rest of the world heavily used the network before its seizure, in many cases to facilitate large scale drug trafficking. The operation is one of, if not the, largest law enforcement mass hacking operation to date, with investigators obtaining more than a hundred million encrypted messages. "The NCA has been collaborating with the Gendarmerie on Encrochat for over 18 months, as the servers are hosted in France. The ultimate objective of this collaboration has been to identify and exploit any vulnerability in the service to obtain content," the document reads, referring to both the UK's National Crime Agency and one of the national police forces of France. As well as the geolocation, chat messages, and passwords, the law enforcement malware also told infected Encrochat devices to provide a list of WiFi access points near the device, the document reads.' -- source: https://yro.slashdot.org/story/20/09/15/1517203 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/

From <https://www.theregister.com/2020/09/12/follow_security_basics_and_you/>: Paying a ransom does not guarantee decryption of data. Open source reporting indicates several instances where an entity paid the ransom but the keys to decrypt the data were not provided. The ACSC has also seen cases where the ransom was paid, the decryption keys were provided, but the adversary came back a few months later and deployed ransomware again. The likelihood that an Australian [organisation] will be retargeted increases with every successful ransom payment. ...

DPL: Debian Project Has Plenty Of Money But Not Enough Developers
by Lawrence D'Oliveiro 11 Sep '20

11 Sep '20

A report <https://www.theregister.com/2020/09/10/debian_project_address/> by the current Debian Project Leader, Jonathan Carter, on the current state of the Mother Of All Linux Distros. They are not short of funds, but they have too few project contributors trying to do too much: The culture of the community is not to spend money unnecessarily. “Debianites don’t like spending money,” he said. “They feel guilty.” It’s probably also the largest Linux distro: In 2009, there were 22,000 binary packages for the i386 architecture in Lenny, the current release at the time. Today there are over 61,000 amd64 binary packages in Bullseye, the forthcoming release. After Bullseye, “100,000 packages is a serious reality on the horizon,” he said. I like this quote: “Debian is a bottomless pit of problems. It’s inherent in the work we do. We’re affected by nearly every problem that exists in the realm of computer science.” How about that for the ultimate geek brag? 🐧

Some Of Our Open-Access Journals Are Missing
by Lawrence D'Oliveiro 11 Sep '20

11 Sep '20

“Open-Access” scientific journals make research papers available online for free. They have become popular as awareness has spread of the practices of traditional publishers like Elsevier, which charge research groups to publish their papers in journals, and then charge hefty subscription fees to those same groups, and all the rest of their customers, for copies of those journals. And then claiming copyright on those papers, on top of it. (And what about the parties the providing the most expensive part of the publication service, namely the fellow researchers doing the peer review? Nope, they don’t get any payment for this at all.) However, this does make the financial model of these Open-Access journals a bit precarious. And perhaps it’s not too surprising that several of them have disappeared since their founding. Operations like the Internet Archive do have the resources to grab copies of their content before they do, but it helps to be aware that these sorts of sites are particularly vulnerable to vanishing. <https://www.theregister.com/2020/09/10/open_access_journal/>

System76’s Lemur Pro: A powerful, ultralight OEM Linux laptop
by Peter Reutemann 11 Sep '20

'System76's Lemur Pro is a 14.1-inch, lightweight powerhouse of an OEM Linux laptop, with an attractive black-finished magnesium-aluminum alloy chassis. If you're looking for a laptop that gets the occasional jealous look at coffee shops (or technical conferences), the Lemur Pro will not disappoint. As configured at $1,563, the Lemur Pro is not a cheap laptop—but it doesn't look, feel, or perform like one, either. The Intel Comet Lake CPU wouldn't be our first choice if we designed a laptop from scratch, but as an entire system, it's hard to find much fault with the Lemur Pro—particularly when limiting the field to OEM Linux laptops alone.' -- source: https://arstechnica.com/gadgets/2020/09/system76s-lemur-pro-a-powerful-ultr… 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/

Android 11 Go Could Make Cheap Phones Up To 20% Faster
by Peter Reutemann 11 Sep '20

11 Sep '20

'Following the official release of Android 11 earlier this week, Google also has some updates in store for the stripped-down version of Android designed for phones with lower specs. From a report: For Android 11 (Go Edition), the most important upgrade is just generally speedier performance, with Google claiming that apps will launch 20% faster in Android 11 Go compared to Android 10 Go. Meanwhile, when it comes to messaging, Android 11 Go is also getting a dedicated section for conversations in the notification tray, so you can see all your ongoing texts in one place, regardless of the specific app. On top of that, Android 11 Go is also getting Google's gesture-based navigation just like vanilla Android 11. Instead of a row of buttons along the bottom of the screen, you can swipe up to go home, swipe in from either side to go back, or swipe up and hold to see your recently used apps. Also, with digital privacy becoming increasingly important, Google is giving Android 11 Go more granular security settings including the ability to grant apps access to hardware like cameras, microphones, or GPS on a one-time basis. And when it comes to apps you haven't used in a long time, Android 11 Go will automatically reset app permissions to prevent old settings that you've probably forgotten about from comprising your security. But perhaps the biggest change for Android 11 Go is that previously, Go Editions of Android were limited to phones with 1GB of RAM. However, with smartphone memory becoming cheaper and more accessible, Android 11 Go has been updated to support phones with up to 2GB of RAM.

Ransomware Accounted For 41% of All Cyber Insurance Claims in H1 2020
by Peter Reutemann 11 Sep '20

11 Sep '20

'Ransomware incidents accounted for 41% of cyber insurance claims filed in the first half of 2020, according to a report published today by Coalition, one of the largest providers of cyber insurance services in North America. From a report: The high number of claims comes to confirm previous reports from multiple cyber-security firms that ransomware is one of today's most prevalent and destructive threats. "Ransomware doesn't discriminate by industry. We've seen an increase in ransom attacks across almost every industry we serve," Coalition added. "In the first half of 2020 alone, we observed a 260% increase in the frequency of ransomware attacks amongst our policyholders, with the average ransom demand increasing 47%," the company added. Among the most aggressive gangs, the cyber insurer listed Maze and DoppelPaymer, which have recently begun exfiltrating data from hacked networks, and threatening to release data on specialized leak sites, as part of double extortion schemes. Based on cyber insurance claims filed by customers who faced a ransomware attack in the first half of 2020, Coalition said the Maze ransomware gang was the most greedy, with the group requesting ransom demands six times larger than the overall average.' -- source: https://it.slashdot.org/story/20/09/10/1829253 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 Browser Adds a Pause Button For the Internet
by Peter Reutemann 10 Sep '20

10 Sep '20

'It can be hard to tear yourself away from the never-ending stream of content provided by the internet, so Vivaldi decided to make taking a break easier by introducing a pause button. PCMag reports: Version 3.3 of the Vivaldi browser introduces a new feature called "Break Mode." Rather than having to close your browser, Break Mode allows you to effectively pause your access to the internet with a button press. Once installed, Vivaldi 3.3 displays a pause button on the status bar. When pressed, Break Mode is engaged, which "mutes and stops HTML5 audio and videos, hides all tabs, panels, and other content leaving the screen clean." It's also possible to trigger Break Mode with the keyboard shortcut Ctrl + "." and to activate it via the browser's Quick Commands. The Vivaldi team sees it as a way of allowing you to "interact with the physical world" while at the same time not having to remember which tabs you had open or what you were viewing when you're ready to return. Pressing the pause button again resumes access just as you left it. Break Mode also acts as a very simple and quick way to hide what you were doing on the internet, which could come in very handy seeing as we're spending so much more time at home together. Other new features include more options for customizing themes as well as adding a new "Private" theme, highlighting base domains to help identify malicious web pages, easier cropping of URLs in the address bar making it easier to visit different parts of a website, and enhancements to the built-in tracker and ad blocker allowing whole pages to be easily blocked.' -- source: https://tech.slashdot.org/story/20/09/09/1933207 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 10 Themes Can Be Abused To Steal Windows Passwords
by Peter Reutemann 09 Sep '20

09 Sep '20

'Specially crafted Windows 10 themes and theme packs can be used in 'Pass-the-Hash' attacks to steal Windows account credentials from unsuspecting users. Windows allows users to create custom themes that contain customized colors, sounds, mouse cursors, and the wallpaper that the operating system will use. Windows users can then switch between different themes as desired to change the appearance of the operating system. A theme's settings are saved under the %AppData%\Microsoft\Windows\Themes folder as a file with a .theme extension, such as 'Custom Dark.theme.' Windows themes can then be shared with other users by right-clicking on an active theme and selecting 'Save theme for sharing,' which will package the theme into a '.deskthemepack' file. These desktop theme packs can then be shared via email or as downloads on websites, and installed by double-clicking them. This weekend security researcher Jimmy Bayne (@bohops) revealed that specially crafted Windows themes could be used to perform Pass-the-Hash attacks. Pass-the-Hash attacks are used to steal Windows login names and password hashes by tricking a user into accessing a remote SMB share that requires authentication. When trying to access the remote resource, Windows will automatically try to login to the remote system by sending the Windows user's login name and an NTLM hash of their password. In a Pass-the-Hash attack, the sent credentials are harvested by the attackers, who then attempt to dehash the password to access the visitors' login name and password.' -- source: https://tech.slashdot.org/story/20/09/08/2017228 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/

Amiga Fast File System Makes Minor Comeback In New Linux Kernel
by Peter Reutemann 09 Sep '20

09 Sep '20

'The Amiga Fast File System (AFFS) is making a minor comeback in the new version of the Linux kernel. The Register reports: As noted by chief penguin Linus Torvalds in his weekly state-of-the-kernel report, a change to AFFS popped up among what he described as a collection of "the usual suspects" in new submissions to the kernel over the last week. The Amiga was ahead of its time, but is now largely a curiosity. However Suse developer David Sterba has noticed that "The basic permission bits (protection bits in AmigaOS) have been broken in Linux' AFFS - it would only set bits, but never delete them. Also, contrary to the documentation, the Archived bit was not handled." "Let's fix this for good, and set the bits such that Linux and classic AmigaOS can coexist in the most peaceful manner," he added. Torvalds appears to have agreed inasmuch as Sterba's code has made it into rc4 of version 5.9 of the Linux kernel. Torvalds said that while rc4 is a big release -- he rated it as "larger than usual" -- it's still "well within the normal range, and not something I'll lose any sleep over."' -- source: https://linux.slashdot.org/story/20/09/08/203224 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 Begins Rolling Out Android 11
by Peter Reutemann 09 Sep '20

'Google today launched Android 11, the latest version of its mobile OS, and pushed the source code to the Android Open Source Project (AOSP). From a report: Unlike previous major versions, Android 11 is not only arriving as an over-the-air update to Pixel phones first, but also on OnePlus, Xiaomi, Oppo, and Realme phones "with more partners launching and upgrading devices over the coming months." That's a major departure for Android, updates for which take months to arrive thanks to carriers and device makers dragging their feet. It doesn't help that Android is the dominant mobile operating system available on thousands of different device configurations, powering over 2.5 billion monthly active devices. [...] Android 11 brings a long list of new features. Google originally split them into three themes: People, Controls, and Privacy. But there is also support for 5G, new screen types, and call screening. There's even a frame rate API for helping apps and games adopt variable refresh rates, which will be a big focus over the next few years as phones and TVs adopt the feature from computer monitors. Google also expanded the Neural Networks API for running computationally intensive machine learning operations.' -- source: https://tech.slashdot.org/story/20/09/08/1710224 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/

Western Digital is trying to redefine the word “RPM”
by Peter Reutemann 08 Sep '20

08 Sep '20

'Last week, the fine Redditors of /r/DataHoarder got upset with Western Digital again—this time, for misrepresenting the rotational speed of their WD Red Network Attached Storage hard drives. (Although the linked post brings things to a head, members of the German-language forum hardwareluxx.de began investigating the issue more than year ago.) We found this controversy reminiscent of earlier complaints that Western Digital was not properly disclosing use of Shingled Magnetic Recording technology in their NAS drives. But the new complaint is that Western Digital calls 7200RPM drives "5400 RPM Class"—and the drives' own firmware report 5400 RPM via the SMART interface. Recently, redditor /u/Amaroko set out to prove or disprove earlier netizens' findings. For each of several drive models, Amoroko placed a sample of that drive on an empty cardboard box, with a Blue Yeti mic held directly above it, then powered the drive on. Spectral analysis of the recorded audio using Adobe Audition showed a baseline frequency of 120Hz for two models of WD 8TB "5400 RPM class" drive. 120 cycles/sec multiplied to 60 secs/min comes to 7,200 cycles/min. So in other words, these "5400 RPM class" drives really were spinning at 7,200rpm.' -- source: https://arstechnica.com/gadgets/2020/09/western-digital-is-trying-to-redefi… 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/

Arm's New Linux-Capable Cortex-R82 Processor Will Enable Drives That Both Store and Process Data
by Peter Reutemann 07 Sep '20

07 Sep '20

'"Arm has announced its first 64 bit, Linux-capable Cortex-R processor, designed for computational storage solutions," reports Electronics Weekly. SiliconAngle calls it "a chip designed to enable a new generation of storage devices that will not only hold data but also help process it." Such devices are part of an emerging hardware category known as computational storage. The technology promises to provide a speed boost for latency-sensitive workloads such as machine learning and real-time analytics applications. Normally, the task of storing data and processing it is relegated to separate components inside a system. The disk or flash drive holds onto the information while a separate processor does the processing. Data has to travel from the storage drive to the processor and back every time an operation is carried out, which creates delays that can slow down performance. The emerging computational storage devices Arm targets attempt to do away with these delays to speed up applications. Instead of sending information to a separate chip for processing, the storage drive processes it locally using its built-in controller. A controller is a tiny computing module inside flash and disk drives that normally performs only low-level tasks such as writing and reading data. Arm's new Cortex-R82 is designed to serve as the controller for computational storage devices. It's available as a chip design that hardware makers can license and customize based on their needs. "The extra computing power allows the chip to run a full Linux distribution as well as applications, all directly inside a storage drive."' -- source: https://hardware.slashdot.org/story/20/09/06/0110227 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/

Is There A Google-Free Future For Firefox?
by Peter Reutemann 07 Sep '20

07 Sep '20

'Forbes reports: Firefox is exploring subscriptions and other "value exchange" services to ease its financial dependence on rival Google, according to the browser's lead developer. Firefox maker, Mozilla, is in the uneasy position of being financially dependent on its search deal with Google, which accounts for the majority of the organization's revenue. Although Mozilla only last month renewed the search deal, ensuring Google remains the default search engine for Firefox in the U.S. and other territories, the company is keen to explore other ways of raising revenue, including charging users for services. Mozilla's partnership with Google is an uncomfortable alliance, not only because the companies distribute rival browsers, but because their values are markedly different. While Google generates the vast bulk of its revenue from online advertising, Firefox's developers expend much of their effort creating tools that thwart advertisers, including the automatic blocking of third-party tracking tools and social-media trackers. "At Mozilla, we tend to believe things are at their best when users have this transparent value exchange," said Dave Camp, senior vice president of Firefox at Mozilla.

Do Developers Trust Each Other Too Much?
by Lawrence D'Oliveiro 06 Sep '20

06 Sep '20

From <https://www.theregister.com/2020/09/04/disclosure_developer_targeting/>: ... much of it is down to exploiting the trust developers put into shared code and software stacks. By selecting a developer and studying their projects, an attacker would be able to map out the software stack being used. From there, the attacker would pick out a weak spot in that stack – say, a dependency or GitHub project – and slip poisoned code in. This could be as simple as slipping attack code into StackOverflow. ... "Most developers consider themselves to be moderately intelligent but not stupid," mused Jones. "I have found most developers are highly intelligent, but also highly stupid."

'Linusgate': Debian Project Leaders Want To Ban Linus Torvalds For His Manners
by Peter Reutemann 06 Sep '20

06 Sep '20

'Artem S. Tashkinov writes: 253 emails have been leaked from private (high-level) mailing lists of Debian, in which its representatives vocally complain about the talk Linus Torvalds gave at the most recent DebConf conference. Some people insist that he should be permanently banned from future conferences because the language he uses is inappropriate and infringes on the project's Code of Conduct. This could set a very bad precedent for the open source community, which has recently seen an influx of various CoC policies applied to a number of high-profile projects mostly after very vocal concerns from the people who barely participate in the open source community. Some observers believe that it's a plot by Microsoft to destroy the open source movement from the inside.' -- source: https://linux.slashdot.org/story/20/09/04/2218239 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/

AWS Introduces a Rust Language-Oriented Linux for Containers
by Peter Reutemann 06 Sep '20

06 Sep '20

'ZDNet reports: An anonymous reader shares this enthusiastic report from ZDNet: Earlier this year, Linus Torvalds approved of adding drivers and other components in Rust to Linux.* Last week, at the virtual Linux Plumbers Conference, developers gave serious thought to using the Rust language for new Linux inline code. ["Nothing firm has been determined yet," reported Phoronix, "but it's a topic that is still being discussed."] And, now Amazon Web Services (AWS) has announced that its just-released Bottlerocket Linux for containers is largely written in Rust. Mozilla may have cut back on Rust's funding, but with Linux embracing Rust, after almost 30-years of nothing but C, Rust's future is assured. Rust was chosen because it lends itself more easily to writing secure software. Samartha Chandrashekar, an AWS Product Manager, said it "helps ensure thread safety and prevent memory-related errors, such as buffer overflows that can lead to security vulnerabilities." Many other developers agree with Chandrashekar. Bottlerocket also improved its security by using Device-mapper's verity target. This is a Linux kernel feature that provides integrity checking to help prevent attackers from overwriting core system software or other rootkit type attacks. It also includes the extended Berkeley Packet Filter (eBPF), In Linux, eBPF is used for safe and efficient kernel function monitoring. * Linus's exact words were "people are actively looking at, especially doing drivers and things that are not very central to the kernel itself, and having interfaces to do those, for example, in Rust. People have been looking at that for years now. I'm convinced it's going to happen one day." The article also reminds readers that AWS's Bottlerocket "is also designed to be quick and easy to maintain... by including the bare essentials needed to run containers..." "Besides its standard open-source elements, such as the Linux kernel and containerd container runtime, Bottlerocket's own code is licensed under your choice of either the Apache 2.0 or the MIT license."' -- source: https://linux.slashdot.org/story/20/09/04/2342226 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/

Spotting Security Vulns By Monitoring The Linux Kernel Mailing List
by Lawrence D'Oliveiro 05 Sep '20

05 Sep '20

This research <https://www.theregister.com/2020/09/04/linux_kernel_flaws/> shows that it is possible to get clues about security vulnerabilities in the Linux kernel simply by looking for patches published with lower than usual discussion about their purpose. In some cases they were able to spot these up to nearly 6 months in advance of their being publicly disclosed. Not all such patches are to address security issues. With itself raises other troubling questions. And of course, mailing lists for other open-source projects can be just as fruitful sources of similar information.

Is It Plugged In?
by Lawrence D'Oliveiro 05 Sep '20

A standard question with phone- or online-based troubleshooting is to ask the user if the misbehaving gear in question is actually plugged in. Sometimes they take the implication less than kindly. But here <https://forums.theregister.com/forum/all/2020/09/04/on_call/#c_4102668> is a wonderfully tactful way to phrase the question: If it was obvious from the phone call that the power wasn't on, she would tell the user that they'd had problems with a batch [of] power cables and ask them to check the serial number on the wall plug. After a minute she usually got a sheepish reply that the problem seemed to have gone away....

nload - network throughput monitor
by Peter Reutemann 05 Sep '20

05 Sep '20

Hi there When being logged into servers remotely, pulling large docker images can take quite a while. On my desktop, I find the network traffic monitor in my taskbar rather handy to check throughput and whether a large transfer across the network has finished. However, I've always wanted to have an alternative for the console. Well, the other week I came across one that suits me: nload - Real time network traffic monitor for the text console https://github.com/rolandriegel/nload Available from Arch/Debian/Ubuntu repos (package "nload").

Lenovo Releases First Fedora Linux ThinkPad Laptop
by Peter Reutemann 04 Sep '20

04 Sep '20

'Today, Lenovo has released a ThinkPad with Red Hat's community Linux, Fedora. ZDNet reports: First in this new Linux-friendly lineup is the X1 Carbon Gen 8. It will be followed by forthcoming versions of the ThinkPad P1 Gen2 and ThinkPad P53. While ThinkPads are usually meant for business users, Lenovo will be happy to sell the Fedora-powered X1 Carbon to home users as well. The new X1 Carbon runs Fedora Workstation 32. This cutting-edge Linux distribution uses the Linux Kernel 5.6. It includes WireGuard virtual private network (VPN) support and USB4 support. This Fedora version uses the new GNOME 3.36 for its default desktop. The system itself comes standard with a 10th Generation Intel Core 1.6Ghz i5-10210U CPU, with up to 4.20 GHz with Turbo Boost. This processor boasts 4 Cores, 8 Threads, and a 6 MB cache. It also comes with 8MBs of LPDDR3 RAM. Unfortunately, its memory is soldered in. While that reduces the manufacturing costs, Linux users tend to like to optimize their hardware and this restricts their ability to add RAM. You can upgrade it to 16MBs, of course, when you buy it for an additional $149. For storage, the X1 defaults to a 256GB SSD. You can push it up to a 1TB SSD. That upgrade will cost you $536. The X1 Carbon Gen 8 has a 14.0" Full High Definition (FHD) (1920 x 1080) screen. For practical purposes, this is as high-a-resolution as you want on a laptop. I've used laptops with Ultra High Definition (UHD), aka 4K, with 3840x2160 resolution, and I've found the text to be painfully small. This display is powered by an integrated Intel HD Graphics chipset. For networking, the X1 uses an Intel Wi-Fi 6 AX201 802.11AX with vPro (2 x 2) & Bluetooth 5.0 chipset. I've used other laptops with this wireless networking hardware and it tends to work extremely well. The entire default package has a base price of $2,145. For now, it's available for $1,287. If you want to order one, be ready for a wait. You can expect to wait three weeks before Lenovo ships it to you.' -- source: https://linux.slashdot.org/story/20/09/03/206205 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/

ARM Co-Founder Hermann Hauser: 'It's In Nvidia's Interests To Destroy Arm'
by Peter Reutemann 04 Sep '20

04 Sep '20

'SoftBank is in advanced talks with US chip company Nvidia to sell Arm -- with a price in the region of 32 billion euros reportedly being thrown around. But Nvidia's purchase of the Cambridge-based chip designer would not only strike a blow to the UK's technological sovereignty, but would result in the destruction of Arm itself, Arm co-founder Hermann Hauser has claimed. Nvidia recently overtook Intel as the most valuable microprocessor company in the world, and its great wealth right now provides it a unique opportunity, says Hauser. "They are the semiconductor company that can buy Arm to destroy it -- and it is very much in its interest to destroy Arm because they [would] gain a lot more than the 40 billion that they pay for it," he claims. Hauser says the acquisition would allow Nvidia to swipe "the microprocessor crown from Intel", and become the chip supplier for 95 per cent of mobile phones, 90 per cent of embedded controllers for the internet of things, as well as taking the PC and data centre markets. Hauser says that an Arm acquisition is a means for Nvidia to become the dominant microprocessor company in the world, "at the same time as they can prevent their main competitors" from making use of further Arm developments. Instead, competitors would need to "scramble" to create their own architecture, handing Nvidia the edge. Up until now, Arm's business model is acting as the "Switzerland of the semiconductor industry" -- maintaining relations with many customers around the world. "Most of them of course, are competitors of Nvidia," says Hauser. Japanese technology investment firm SoftBank acquired Arm in 2016, but ensured the company's continued neutrality.

Hackers are exploiting a critical flaw affecting >350,000 WordPress sites
by Peter Reutemann 03 Sep '20

03 Sep '20

'Hackers are actively exploiting a vulnerability that allows them to execute commands and malicious scripts on Websites running File Manager, a WordPress plugin with more than 700,000 active installations, researchers said on Tuesday. Word of the attacks came a few hours after the security flaw was patched. Attackers are using the exploit to upload files that contain webshells that are hidden in an image. From there, they have a convenient interface that allows them to run commands in plugins/wp-file-manager/lib/files/, the directory where the File Manager plugin resides. While that restriction prevents hackers from executing commands on files outside of the directory, hackers may be able to exact more damage by uploading scripts that can carry out actions on other parts of a vulnerable site. NinTechNet, a website security firm in Bangkok, Thailand, was among the first to report the in-the-wild attacks. The post said that a hacker was exploiting the vulnerability to upload a script titled hardfork.php and then using it to inject code into the WordPress scripts /wp-admin/admin-ajax.php and /wp-includes/user.php.' -- source: https://arstechnica.com/information-technology/2020/09/hackers-are-exploiti… 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 Developers Continue Evaluating The Path To Adding Rust Code To The Kernel
by Peter Reutemann 31 Aug '20

31 Aug '20

'Phoronix reports: As mentioned back in July, upstream Linux developers have been working to figure out a path for adding Rust code to the Linux kernel. That topic is now being further explored at this week's virtual Linux Plumbers Conference... To be clear though, these Rust Linux kernel plans do not involve rewriting large parts of the kernel in Rust (at least for the foreseeable future...), there would be caveats on the extent to which Rust code could be used and what functionality, and the Rust support would be optional when building the Linux kernel. C would remain the dominant language of the kernel and then it's just a matter of what new functionality gets added around Rust if concerned by memory safety, concurrency, and other areas where Rust is popular with developers. Various upstream developers have been interested in Rust for those language benefits around memory safety and security as well as its syntax being close to C. There would be a to-be-determined subset of Rust to be supported by the Linux kernel.... While the Rust code would be optional, the developers do acknowledge there are limitations on where Rust is supported due to the LLVM compiler back-ends. But at least for x86/x86_64, ARM/ARM64, POWER, and other prominent targets there is support along with the likes of RISC-V. Nothing firm has been determined yet but it's a topic that is still being discussed at the virtual LPC this week and surely over the weeks/months ahead on the kernel mailing list. There is Rust-For-Linux on GitHub with a prototype kernel module implementation. There is also the PDF slides from Thursday's talk on the matter. It's not clear to me that this is a done deal. But the article argues that "it's still looking like it will happen, it's just a matter of when the initial infrastructure will be in place and how slowly the rollout will be..."' -- source: https://linux.slashdot.org/story/20/08/29/2250237 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/

HBO Max Cranks Up the Widevine DRM, Leaves Linux Users in the Cold
by Peter Reutemann 27 Aug '20

27 Aug '20

'Jim Salter, reporting for ArsTechnica: A reader tipped us off today that HBO Max stopped working a couple of weeks ago for Linux users, under any Web browser. Any attempt to play back a video on the streaming service on a Linux system -- regardless of distribution or browser -- returns an error saying, "We're having trouble playing this video. Please try again later." Unfortunately, trying again later won't help -- the root cause of the problem is that the Widevine DRM attempting to protect HBO Max's content from pirates is refusing to recognize any Linux system as a known platform. We saw the same thing happen in January, when CBS All Access suddenly stopped working on Linux in the same way. When we asked CBS executives if they had enabled the Verified Media Path (VMP) requirement on their Widevine server, they suddenly clammed up -- but later that day, the service miraculously worked for Linux users again. We did verify that HBO Max will not work on Linux browsers and that the problem is -- once again -- Widevine DRM refusing to issue a license. Although HBO Max has not returned requests for comment at press time, it seems very likely that the cause here is the same as it was for CBS All Access back in January. It seems like somebody enabled Verified Media Path on the Widevine server, and since the Linux kernel is not a verified media path, Linux users can't get a license and can't watch the content.' -- source: https://slashdot.org/story/20/08/26/1923213 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 alpha release also includes new tools including Animations, Constraint Layouts, and performance optimizations. Android Jetpack, which Google launched at its I/O 2018 developer conference, is a set of components for speeding up app development. Think of it as the successor to Support Library, a set of components that makes it easier to leverage new Android features while maintaining backwards compatibility.

Requiring Plain-Text Email Is A “Barrier To Entry” For Linux Kernel Development, Says Somebody Or Other

As an example, my partner submitted a patch to OpenBSD a few weeks ago, and he had to set up an entirely new mail client which didn’t mangle his email message to HTML-ise or do other things to it, so he could even make that one patch. That’s a barrier to entry that’s pretty high for somebody who may want to be a first-time contributor.” ...

A New Botnet Is Covertly Targeting Millions of Servers
by Peter Reutemann 26 Aug '20

26 Aug '20

'Wired reports: FritzFrog has been used to try and infiltrate government agencies, banks, telecom companies, and universities across the US and Europe. Researchers have found what they believe is a previously undiscovered botnet that uses unusually advanced measures to covertly target millions of servers around the world. The botnet uses proprietary software written from scratch to infect servers and corral them into a peer-to-peer network, researchers from security firm Guardicore Labs reported on Wednesday. Peer-to-peer (P2P) botnets distribute their administration among many infected nodes rather than relying on a control server to send commands and receive pilfered data. With no centralized server, the botnets are generally harder to spot and more difficult to shut down. The botnet, which Guardicore Labs researchers have named FritzFrog, has a host of other advanced features, including: In-memory payloads that never touch the disks of infected servers; At least 20 versions of the software binary since January; A sole focus on infecting secure shell, or SSH, servers that network administrators use to manage machines; The ability to backdoor infected servers; and A list of login credential combinations used to suss out weak login passwords that's more "extensive" than those in previously seen botnets. Taken together, the attributes indicate an above-average operator who has invested considerable resources to build a botnet that's effective, difficult to detect, and resilient to takedowns. The new code base -- combined with rapidly evolving versions and payloads that run only in memory -- make it hard for antivirus and other end-point protection to detect the malware. The botnet has so far succeeded in infecting 500 servers belonging to "well-known universities in the US and Europe, and a railway company."Once installed, the malicious payload can execute 30 commands, including those that run scripts and download databases, logs, or files. To evade firewalls and endpoint protection, attackers pipe commands over SSH to a netcat client on the infected machine. Netcat then connects to a "malware server." (Mention of this server suggests that the FritzFrog peer-to-peer structure may not be absolute. Or it's possible that the "malware server" is hosted on one of the infected machines, and not on a dedicated server. Guardicore Labs researchers weren't immediately available to clarify.)' -- source: https://it.slashdot.org/story/20/08/25/1947246 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/

I got so sick of hearing it with all the pre-launch and post-launch hype, as the song was tied heavily to the Win 95 launch event. Microsoft paid the Stones a princely sum to use it. I still remember how exciting it was to see the full-length, full-screen video included on the installation CD-ROM, "Buddy Holly" by Weezer. Mind-blowing to watch a whole music video on your computer. Crappy resolution by our standards today, and a very limited palette to my memory. But as I said, amazing in the day. Windows 95 had many fans and many critics. At the time, I recall it as an exciting OS (or GUI on top of DOS, if you prefer). PC users were riveted to all the magazine and other media coverage pre-launch. I remember it fondly (with all the obligatory respect due Mac OS, the Amiga, and all the other early GUIs of course).' -- source: https://tech.slashdot.org/story/20/08/25/1936234 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/

Chinese-Made Smartphones Are Secretly Stealing Money From People Around the World
by Peter Reutemann 25 Aug '20

25 Aug '20

'When Mxolosi saw a Tecno W2 smartphone in a store in Johannesburg, South Africa, he was attracted to its looks and functionality. But what really drew him in was the price, roughly $30 -- far less than comparable models from Samsung, Nokia, or Huawei, Africa's other top brands. It was another sale for Transsion, the Chinese company that makes Tecno and other low-priced smartphones, as well as basic handsets, for the developing world. Since releasing its first smartphone in 2014, the upstart has grown to become Africa's top handset seller, beating out longtime market leaders Samsung and Nokia. But its success can come at a price. Mxolosi, an unemployed 41-year-old, became frustrated with his Tecno W2. Pop-up ads interrupted his calls and chats. He'd wake up to find his prepaid data mysteriously used up and messages about paid subscriptions to apps he'd never asked for. He thought it might be his fault, but according to an investigation by Secure-D, a mobile security service, and BuzzFeed News, software embedded in his phone right out of the box was draining his data while trying to steal his money. Mxolosi's Tecno W2 was infected with xHelper and Triada, malware that secretly downloaded apps and attempted to subscribe him to paid services without his knowledge. Secure-D's system, which mobile carriers use to protect their networks and customers against fraudulent transactions, blocked 844,000 transactions connected to preinstalled malware on Transsion phones between March and December 2019. Secure-D Managing Director Geoffrey Cleaves told BuzzFeed News that Mxolosi's data was used up by the malware as it attempted to subscribe him to paid services. Along with South Africa, Tecno W2 phones in Ethiopia, Cameroon, Egypt, Ghana, Indonesia, and Myanmar were infected.' -- source: https://it.slashdot.org/story/20/08/24/2139209 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/

Bridgefy, the Messenger Promoted For Mass Protests, Is a Privacy Disaster
by Peter Reutemann 25 Aug '20

25 Aug '20

'Bridgefy, a popular messaging app for conversing with one another when internet connections are heavily congested or completely shut down, is a privacy disaster that can allow moderately-skilled hackers to take a host of nefarious actions against users, according to a paper published on Monday. The findings come after the company has for months touted the app as a safe and reliable way for activists to communicate in large gatherings. Ars Technica reports: By using Bluetooth and mesh network routing, Bridgefy lets users within a few hundred meters -- and much further as long as there are intermediary nodes -- to send and receive both direct and group texts with no reliance on the Internet at all. Bridgefy cofounder and CEO Jorge Rios has said he originally envisioned the app as a way for people to communicate in rural areas or other places where Internet connections were scarce. And with the past year's upswell of large protests around the world -- often in places with hostile or authoritarian governments -- company representatives began telling journalists that the app's use of end-to-end encryption (reiterated here, here, and here) protected activists against governments and counter protesters trying to intercept texts or shut down communications. [R]esearchers said that the app's design for use at concerts, sports events, or during natural disasters makes it woefully unsuitable for more threatening settings such as mass protests. They wrote: "Though it is advertised as 'safe' and 'private' and its creators claimed it was secured by end-to-end encryption, none of aforementioned use cases can be considered as taking place in adversarial environments such as situations of civil unrest where attempts to subvert the application's security are not merely possible, but to be expected, and where such attacks can have harsh consequences for its users. Despite this, the Bridgefy developers advertise the app for such scenarios and media reports suggest the application is indeed relied upon." The researchers are: Martin R. Albrecht, Jorge Blasco, Rikke Bjerg Jensen, and Lenka Marekova from Royal Holloway, University of London. After reverse engineering the app, they devised a series of devastating attacks that allow hackers -- in many cases with only modest resources and moderate skill levels -- to take a host of nefarious actions against users. The attacks allow for: deanonymizing users; building social graphs of users' interactions, both in real time and after the fact; decrypting and reading direct messages; impersonating users to anyone else on the network; completely shutting down the network; and performing active man-in-the-middle attacks, which allow an adversary not only to read messages, but to tamper with them as well. "The key shortcoming that makes many of these attacks possible is that Bridgefy offers no means of cryptographic authentication, which one person uses to prove she's who she claims to be," the report adds. "Instead, the app relies on a user ID that's transmitted in plaintext to identify each person. Attackers can exploit this by sniffing the ID over the air and using it to spoof another user." The app also uses PKCS #1, an outdated way of encoding and formatting messages so that they can be encrypted with the RSA cryptographic algorithm. "This encoding method, which was deprecated in 1998, allows attackers to perform what's known as a padding oracle attack to derive contents of an encrypted message," reports Ars.' -- source: https://yro.slashdot.org/story/20/08/24/2228219 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 Apologizes To WordPress, Won't Force the Free App To Add Purchases After All
by Peter Reutemann 25 Aug '20

25 Aug '20

'On Friday, the internet erupted in a small way to learn that Apple had successfully forced WordPress to monetize its free app -- forcing it to sell premium plans and custom domain names seemingly just so that Apple could get its traditional 30 percent cut. But one afternoon and evening of surprise and outrage later, Apple is backing off. The company is issuing a rare on-the-record apology, and it says that WordPress will no longer have to add in-app purchases now that all is said and done. Here's Apple's full statement: "We believe the issue with the WordPress app has been resolved. Since the developer removed the display of their service payment options from the app, it is now a free stand-alone app and does not have to offer in-app purchases. We have informed the developer and apologize for any confusion that we have caused." You'll notice that Apple is positioning this as the developer -- WordPress -- having done the right thing and removed the "display of their service payment options from the app," and to my knowledge that is technically true. But as far as I'm aware, that didn't happen today: it happened weeks or months ago.' -- source: https://apple.slashdot.org/story/20/08/24/204211 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 Sustainability is Really a People Problem
by Peter Reutemann 24 Aug '20

24 Aug '20

'Matt Asay, a former COO of Canonical now working at AWS, argues that the question of open source sustainability "is really a people problem." But to make the case, he cites comments by Tobie Langel, formerly W3C's testing lead (and a former member of Facebook's Open Source and Web Standards Team) who's now founded an open-source strategies consulting firm whose clients include Mozilla, Intell, Google, and Microsoft. Much of the "open source sustainability" discussion has focused on the one thing that really needs no help being sustained: software. As Tobie Langel rightly points out, "Open source code isn't a scarce resource. It's the exact opposite, actually: It's infinitely reproducible at zero cost to the user and to the ecosystem." Nor is sustainability really a matter of funding, though this gets closer to the truth. No, open source sustainability is really a people problem. Or, as Langel highlights, "In open source, the maintainers working on the source code are the scarce resource that needs to be protected and nurtured." Over the past several weeks, I've interviewed a number of maintainers for popular open source projects. In every case, they talked about how they contribute because it's fun, but also acknowledged that some aspects of open source development can make it decidedly "un-fun" (e.g., demanding users who complain about missing features or existing bugs but don't contribute code or fixes). Most have found ways to turn their passion into financial independence, but Langel stresses that cash is critical to keeping open source humming along... "Without revenue, there is no maintenance, and without maintenance, the commons becomes toxic very quickly... As new security issues are discovered, open source code that isn't updated becomes a security risk..." Langel is absolutely correct to argue, "In an ecosystem with infinite resources, the attention needs to be on the people taking care of and maintaining that resource, because that's where the bottleneck is." Again, that's partly a question of money, but it's even more a question of treating people with dignity and respect, while making open source communities a fun, welcoming place.' -- source: https://news.slashdot.org/story/20/08/23/0447224 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/

Virtual Influencers: Who Needs Real People?
by Lawrence D'Oliveiro 23 Aug '20

23 Aug '20

You probably know that celebrities can earn a lot by promoting products to their followers on social media. Some of these don’t actually have a flesh-and-blood job: they are famous for nothing more than being such “influencers”. Some advertisers have now decided to shortcut the process by creating their own “virtual influencers”: essentially, animated CG characters that they can control totally and much more easily than managing real people <https://www.theregister.com/2020/08/21/virtual_instagram_influencers/>. If all their interactions happen online, why do they need to be real?

Chrome/Chromium Now Accounting For Half Of All DNS Root Server Traffic
by Lawrence D'Oliveiro 23 Aug '20

23 Aug '20

Google’s Chrome (and its Chromium-based offshoots) include some elaborate workarounds to detect ISPs hijacking “no such domain” responses to advertise their own DNS services. Unfortunately, these workarounds lead to the generation of a lot of traffic to the DNS root servers <https://www.theregister.com/2020/08/21/chromiums_dns_network/>. Firefox is able to implement something similar, but with less impact on the Internet at large.

Google Fixes Major Gmail Bug Seven Hours After Exploit Details Go Public
by Peter Reutemann 21 Aug '20

21 Aug '20

'Google has patched on Wednesday a major security bug impacting the Gmail and G Suite email servers. From a report: The bug could have allowed a threat actor to send spoofed emails mimicking any Gmail or G Suite customer. According to security researcher Allison Husain, who found and reported this issue to Google in April, the bug also allowed attachers to pass the spoofed emails as compliant with SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting, and Conformance), two of the most advanced email security standards. However, despite having 137 days to fix the reported issue, Google initially delayed patches past the disclosure deadline, planning to fix the bug somewhere in September. Google engineers changed their mind yesterday after Husain published details about the bug on her blog, including proof-of-concept exploit code.' -- source: https://it.slashdot.org/story/20/08/20/1522226 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/

Some Email Clients Are Vulnerable To Attacks Via 'mailto' Links
by Peter Reutemann 21 Aug '20

21 Aug '20

'A lesser-known technology known as "mailto" links can be abused to launch attacks on the users of email desktop clients. From a report: The new attacks can be used to secretly steal local files and have them emailed as attachments to attackers, according to a research paper published last week by academics from two German universities. The "vulnerability" at the heart of these attacks is how email clients implemented RFC6068 -- the technical standard that describes the 'mailto' URI scheme. Mailto refer to special types of links, usually supported by web browsers or email clients. These are links that, when clicked, they open a new email compose/reply window rather than a new web page (website). RFC6068 says that mailto links can support various parameters. When used with mailto links, these parameters will pre-fill the new email window with predefined content.' -- source: https://it.slashdot.org/story/20/08/20/177204 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 Legend Of The Melbourne Citadel
by Lawrence D'Oliveiro 21 Aug '20

21 Aug '20

It appears there is a 2300-foot tall building in Melbourne, at least according to the latest version of Microsoft Flight Simulator <https://www.theregister.com/2020/08/20/flight_simulator_bing_fawkner_tower/>. This would make it the second-tallest in the world. It originated from a mistaken entry into the OpenStreetMap database (since corrected), which Flight Simulator nevertheless managed to incorporate into its map data. There’s even a linked video of a player trying to land on it, before a future update deletes it from the game. Spoiler alert: yes, you can land, with the right sort of aircraft and a bit of effort. And you can even take off again. Another amusing item from the report comes from Microsoft’s use of AI to fill in road traffic flows. There is one case where the map data seems to omit the fact that there is a traffic tunnel through a building, with the result that the software has the cars going vertically up and down the sides of the building.

Linux Is Taking Over
by Lawrence D'Oliveiro 21 Aug '20

Seems like The Register’s BorkBorkBork column, featuring public examples of embedded systems falling over, is including more and more Linux-based screwups, e.g. <https://www.theregister.com/2020/08/20/bork/>: RailPoint has form for bork. Its Windows-based signage has already featured in these pages and back then the company told us it was "about to upgrade all of our production machines to a custom Linux build to improve their stability and generally operate with more efficiency". Behold the stability and efficiency. *Sigh*

'Real' Programming Is an Elitist Myth
by Peter Reutemann 20 Aug '20

20 Aug '20

'When people build a database to manage reading lists or feed their neighbors, that's coding -- and culture. From an essay: We are past the New York City Covid-19 peak. Things have started to reopen, but our neighborhood is in trouble, and people are hungry. There's a church that's opened space for a food pantry, a restaurant owner who has given herself to feeding the neighborhood, and lots of volunteers. [...] It's a complex data model. It involves date fields, text fields, integers, notes. You need lots of people to log in, but you need to protect private data too. You'd think their planning conversations would be about making lots of rice. But that is just a data point. The tool the mutual aid group has settled on to track everything is Airtable, a database-as-a-service program. You log in and there's your database. There are a host of tools like this now, "low-code" or "no-code" software with names like Zapier or Coda or Appy Pie. At first glance these tools look like flowcharts married to spreadsheets, but they're powerful ways to build little data-management apps. Airtable in particular keeps showing up everywhere for managing office supplies or scheduling appointments or tracking who at WIRED has their fingers on this column. The more features you use, the more they charge for it, and it can add up quickly. I know because I see the invoices at my company; we use it to track projects. "Real" coders in my experience have often sneered at this kind of software, even back when it was just FileMaker and Microsoft Access managing the flower shop or tracking the cats at the animal shelter. It's not hard to see why. These tools are just databases with a form-making interface on top, and with no code in between. It reduces software development, in all its complexity and immense profitability, to a set of simple data types and form elements. You wouldn't build a banking system in it or a game. It lacks the features of big, grown-up databases like Oracle or IBM's Db2 or PostgreSQL. And since it is for amateurs, the end result ends up looking amateur. But it sure does work. I've noticed that when software lets nonprogrammers do programmer things, it makes the programmers nervous. Suddenly they stop smiling indulgently and start talking about what "real programming" is. This has been the history of the World Wide Web, for example. Go ahead and tweet "HTML is real programming," and watch programmers show up in your mentions to go, "As if." Except when you write a web page in HTML, you are creating a data model that will be interpreted by the browser. This is what programming is. Code culture can be solipsistic and exhausting. Programmers fight over semicolon placement and the right way to be object-oriented or functional or whatever else will let them feel in control and smarter and more economically safe, and always I want to shout back: Code isn't enough on its own. We throw code away when it runs out its clock; we migrate data to new databases, so as not to lose one precious bit. Code is a story we tell about data.' -- source: https://developers.slashdot.org/story/20/08/19/146204 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/

235 Million Instagram, TikTok and YouTube User Profiles Exposed In Massive Data Leak
by Peter Reutemann 20 Aug '20

20 Aug '20

'Forbes: The security research team at Comparitech today disclosed how an unsecured database left almost 235 million Instagram, TikTok and YouTube user profiles exposed online in what can only be described as a massive data leak. The data was spread across several datasets; the most significant being two coming in at just under 100 million each and containing profile records apparently scraped from Instagram. The third-largest was a dataset of some 42 million TikTok users, followed by just under 4 million YouTube user profiles. Comparitech says that, based on the samples it collected, one in five records contained either a telephone number or email address. Every record also included at least some, sometimes all, the following information: Profile name; Full real name; Profile photo; and Account description. Statistics about follower engagement, including: Number of followers; Engagement rate; Follower growth rate; Audience gender; Audience age; Audience location; Likes; Last post timestamp; Age; and Gender. "The information would probably be most valuable to spammers and cybercriminals running phishing campaigns," Paul Bischoff, Comparitech editor, says. "Even though the data is publicly accessible, the fact that it was leaked in aggregate as a well-structured database makes it much more valuable than each profile would be in isolation," Bischoff adds. Indeed, Bischoff told me that it would be easy for a bot to use the database to post targeted spam comments on any Instagram profile matching criteria such as gender, age or number of followers. The data appeared to have originated from a company called Deep Social, which was banned by both Facebook and Instagram in 2018 after scraping user profile data. The company was wound down sometime after this. The researchers reached out to Deep Social, which then forwarded the disclosure to a Hong Kong-registered social media influencer data-marketing company called Social Data. Social Data shut down the database about three hours after the researchers' initial email. "Social Data has denied any connection between itself and Deep Social," reports Forbes, citing Comparitech.' -- source: https://yro.slashdot.org/story/20/08/19/212230 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 86 Will Warn Users About Insecure Forms On HTTPS Pages
by Peter Reutemann 19 Aug '20

19 Aug '20

'While there's wide HTTPS adoption today, HTTP content on secure pages still persists. Google has been working to stamp that out, and Chrome is now turning its attention to and warning about insecure forms. "These 'mixed forms' (forms on HTTPS sites that do not submit on HTTPS) are a risk to users' security and privacy," says Google in a blog post. "Information submitted on these forms can be visible to eavesdroppers, allowing malicious parties to read or change sensitive form data." 9to5Google reports: The Google browser today removes the address bar's lock icon from sites with mixed forms. However, this proved to deliver an "unclear" experience that "did not effectively communicate the risks associated with submitting data in insecure forms." Starting in version 86, due to hit stable in October, Chrome will provide a more aggressive warning about insecure forms. Autofill will be disabled, but the built-in password manager will continue to offer "unique passwords." The company argues it's safer than reusing credentials. Next, the form will show red warning text underneath the field: "This form is not secure. Autofill has been turned off. The last measure will throw up a full-page warning communicating the potential risks. It gives users an option to cancel the action, but there will be a "Send anyway" button.

Linux Kernel NTFS Driver
by Lawrence D'Oliveiro 19 Aug '20

19 Aug '20

This article <https://www.theregister.com/2020/08/18/paragon_tries_to_contribute_ntfs/>, about the submission of a new Linux kernel driver for accessing Microsoft NTFS volumes (i.e. the kind of filesystems that are standard among Windows users), had me confused for a moment. It mentions limitations of the current kernel driver, like not being able to create or delete files or directories. I thought this kind of problem had been solved for Linux over a decade ago. And indeed it has, in the form of NTFS-3G, which is a userspace driver that connects via FUSE, and is available as a standard package for Debian and derivatives. I know this works, because just a few weeks ago, for example, I was at some friends’ place, and transferred several dozen gigabytes of files to an external hard drive of theirs from my Debian-Unstable-running laptop, without thinking twice about it, even though they are exclusively Windows users. I suppose a kernel driver offers higher performance, in principle, than one running in userspace. But I can’t imagine many Linux-based workloads that make heavy use of NTFS volumes.

Microsoft: Improving The “Outage Experience”
by Lawrence D'Oliveiro 19 Aug '20

19 Aug '20

Seems that, when something goes wrong with Microsoft’s cloud service, customers expect to find out what has happened by visiting the Azure Status page. How silly of them <https://www.theregister.com/2020/08/18/dont_use_azure_status_page/>: The place to look, Kubba said, is in the Azure Portal under Service Health. The public Azure status page is "only used to communicate widespread outages" so likely to be ineffective in discovering what may be wrong. "Despite this, we constantly find that customers visit the Azure Status page to determine the health of services on Azure," complained Kubba – though we presume that if an outage blocks access to the portal, the Status page would then be the right place to look. In other cases, it is not much use since "more than 95 per cent of our incidents" do not appear there, according to Kubba. A further complication is that Azure DevOps (which is where Pipelines live) is not integrated into the Azure portal, and many Azure DevOps users only hang around the DevOps portal. Therefore, there is a separate Azure DevOps status page, making this a third site that needs to be bookmarked for tracking outages.

An Alexa Bug Could Have Exposed Your Voice History To Hackers
by Peter Reutemann 18 Aug '20

18 Aug '20

'Findings published on Thursday by the security firm Check Point reveal that Alexa's Web services had bugs that a hacker could have exploited to grab a target's entire voice history, meaning their recorded audio interactions with Alexa. Amazon has patched the flaws, but the vulnerability could have also yielded profile information, including home address, as well as all of the "skills," or apps, the user had added for Alexa. An attacker could have even deleted an existing skill and installed a malicious one to grab more data after the initial attack. [...] For an attacker to exploit the vulnerabilities, they would need first to trick targets into clicking a malicious link, a common attack scenario. Underlying flaws in certain Amazon and Alexa subdomains, though, meant that an attacker could have crafted a genuine and normal-looking Amazon link to lure victims into exposed parts of Amazon's infrastructure. By strategically directing users to track.amazon.com -- a vulnerable page not related to Alexa, but used for tracking Amazon packages -- the attacker could have injected code that allowed them to pivot to Alexa infrastructure, sending a special request along with the target's cookies from the package-tracking page to skillsstore.amazon.com/app/secure/your-skills-page. At this point, the platform would mistake the attacker for the legitimate user, and the hacker could then access the victim's full audio history, list of installed skills, and other account details. The attacker could also uninstall a skill the user had set up and, if the hacker had planted a malicious skill in the Alexa Skills Store, could even install that interloping application on the victim's Alexa account. Both Check Point and Amazon note that all skills in Amazon's store are screened and monitored for potentially harmful behavior, so it's not a foregone conclusion that an attacker could have planted a malicious skill there in the first place. Check Point also suggests that a hacker might be able to access banking data history through the attack, but Amazon disputes this, saying that information is redacted in Alexa's responses. "The security of our devices is a top priority, and we appreciate the work of independent researchers like Check Point who bring potential issues to us," an Amazon spokesperson told WIRED in a statement. "We fixed this issue soon after it was brought to our attention, and we continue to further strengthen our systems. We are not aware of any cases of this vulnerability being used against our customers or of any customer information being exposed."' -- source: https://yro.slashdot.org/story/20/08/17/2129202 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 Notepad++ Banned In China After 'Stand With Hong Kong' Update
by Peter Reutemann 18 Aug '20

18 Aug '20

'The website of Notepad++ is banned in China as of Monday, "obviously due to" its release of editions named "Free Uyghur" and "Stand with Hong Kong," the source code and text editor announced on Twitter. TechCrunch reports: First released in 2003 by France-based developer Don Ho, free-to-use Notepad++ operates on Windows and supports some 90 languages. In his release notices for the two editions, Ho openly voiced his concerns over "human rights" conditions, respectively in the Xinjiang autonomous region and Hong Kong. Tests by TechCrunch found that the Notepad++ ban only applies to its Download page -- which showcases the special editions and thus politically sensitive language -- when one tries to reach it from Chinese browsers developed by Tencent (QQ Browser and WeChat's built-in browser), Alibaba (UC Browser), 360 and Sogou. These services flag the page as containing content "prohibited" by local regulators. Notepad++'s home page, on the other hand, remains unblocked through these local browsers. One can still access the full site from Chrome and DuckDuckGo in China. The ban began as early as August 12 when a user notified Ho of the ban, the developer told TechCrunch. He has never been contacted by any Chinese government authority and does not plan to take measures to cope with the website restriction.' -- source: https://yro.slashdot.org/story/20/08/17/2028235 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/

Reviewer Calls Linux-based PinePhone 'the Most Interesting Smartphone I've Tried in Years'
by Peter Reutemann 17 Aug '20

17 Aug '20

'A review at the Android Police site calls Pine64's new Linux-based PinePhone "the most interesting smartphone I've tried in years," with 17 different operating systems available (including Fedora, Ubuntu Touch, SailfishOS, openSUSE, and Arch Linux ARM): There's a replaceable battery, which is compatible with batteries designed for older Samsung Galaxy J7 phones. It's good to know that even if PinePhone vanished overnight, you could still purchase new batteries for around $10-15... There's a microSD card slot above the SIM tray, which supports cards up to 2TB in size. While it can be used as extra storage, just like the SD slots in Android phones and tablets, it can also function as a bootable drive. If you write an operating system image to the SD card and put it in the PinePhone, the phone will boot from the SD card. This means you can move between operating systems on the PinePhone by simply swapping microSD cards, which is amazing for trying out new Linux distributions without wiping data. How great would it be if Android phones could do that? Finally, the inside of the PinePhone has six hardware killswitches that can be manipulated with a screwdriver. You can use them to turn off the modem, Wi-Fi/Bluetooth, microphone, rear camera, front camera, and headphone jack. No need to put a sticker over the selfie camera if you're worried about malicious software — just flip the switch and never worry about it again.... For a $150 phone produced in limited batches by a company with no previous experience in the smartphone industry, I'm impressed it's built as well as it is... I look forward to seeing what the community around the PinePhone can accomplish. A Pine64 blog post this weekend touts "a boat-load of cool and innovative things" being attempted by the PinePhone community, including users working on things like a fingerprint scanner or a thermal camera, plus a community that's 3D-printing their own custom PinePhone cases. And Pine64 has now identified three candidates for a future keyboard option (each of which can be configured as either a slide-out or clamshell keyboard): I feel like we have finally gotten into a good production rhythm; it was only last month we announced the postmarketOS Community Edition of the PinePhone, and this month I am here to tell you that the factory will deliver the phones to us at the end of this month... I don't know about you, but I think that this is a rather good production pace. At the time of writing, and based on current sale rates, the postmarketOS production-run will sell out in a matter of days... While I have no further announcements at this time, what I will say is that we have no intention of slowing down the pace now until February 2021 (when Chinese New Year begins)...' -- source: https://mobile.slashdot.org/story/20/08/17/0115227 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/

Can Firefox Be Saved?
by Peter Reutemann 17 Aug '20

17 Aug '20

'"Even with another infusion of cash from Google, you have to wonder just how long Firefox will survive as a viable, mainstream web browser," argues ZDNet contributing editor Steven J. Vaughan-Nichols: I've been using Mozilla's Firefox browser since it was still in beta. In 2004, for a while, it was my favorite web browser. Not because it was open-source, but because it was so much better and more secure than Internet Explorer. That was then. This is now. Firefox is in real danger of dying off... Mozilla and Firefox still produced important work. You need to look no further than the JavaScript, Rust, and WebAssembly languages. They were also champions of security and privacy. Projects such as embracing DNS-over-HTTPS (DoH) and overall security improvements were great, but users didn't care. With the arrival of Google's Chrome browser, users turned from Firefox to Chrome as their favorite browser... Firefox is on its way to irrelevance. Making matters even worse, Mozilla's just had its second round of layoffs... As technology writer Matthew MacDonald put it, "Mozilla "." Firefox's security and development teams have also been hard hit. This is bad. In January. Mitchell Baker, Mozilla Corporation CEO and Mozilla Foundation chairperson, said it let people go because of declining interest in Firefox, and thus reduced earnings, and that Mozilla was looking for more revenue from "sources outside of search" but "this did not happen." It still isn't happening. According to Mozilla's latest annual report, the majority of its revenue is still generated from global browser search partnerships. This includes the deal negotiated with Google in 2017... Baker assured onlookers that Mozilla would "ship new products faster and develop new revenue streams." These include its bookmarking app Pocket; its virtual rooms Hubs; and its $4.99-a-month Firefox VPN. Excuse me if I don't buy any of these new revenue sources.... Firefox will live on in one way or the other. It's open source after all. But Firefox as an important browser, or Mozilla as a significant open-source developer hub? No. I can't see it. Those days are done. Firefox is officially on my endangered species list. Technology writer Matthew MacDonald ended his Medium essay on a more hopeful note. "If you have the skills and time, the best possible support is to join the Mozilla community and contribute to their code base."' -- source: https://news.slashdot.org/story/20/08/15/1955237 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/

Happy Birthday to Debian, CPAN, and Mutt
by Peter Reutemann 17 Aug '20

17 Aug '20

'27 years ago today, in 1993, Debian first appeared in the world. August 16th has since been recognized as "DebianDay," celebrated shortly before the annual Debian Conference — with lots of ways to get involved, according to Debian.org: Today is also an opportunity for you to start or resume your contributions to Debian. For example, you can scratch your creative itch and suggest a wallpaper to be part of the artwork for the next release, have a look at the DebConf20 schedule and register to participate online (August 23rd to 29th, 2020), or put a Debian live image in a DVD or USB and give it to some person near you, who still didn't discover Debian. Our favorite operating system is the result of all the work we do together. Thanks to everybody who has contributed in these 27 years, and happy birthday Debian! And the same day is also the 25th anniversary of CPAN, the Comprehensive Perl Archive Network: On the 16th August 1995, Andreas König uploaded Symdump 1.20 to CPAN. There were other things already on CPAN, but this was the first true upload, to be followed by more than 6,500 people who have released over 35,000 distributions in 230k releases. So it seems appropriate that 16th August be designated CPAN Day, to celebrate CPAN, and all the authors who've made it what it is. That blog post urges readers to celebrate the anniversary "by doing something related to CPAN: release something, blog about your favourite module, or email its author thanking her or him." Finally, Slashdot reader JobSnijders reminds us that Mutt is also enjoying a birthday: The email client that aims to suck a little bit less celebrates its 25th anniversary!' -- source: https://linux.slashdot.org/story/20/08/16/1652249 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 Qualcomm Shook Down The Cell Phone Industry For Almost 20 Years
by Lawrence D'Oliveiro 15 Aug '20

15 Aug '20

A pretty sobering read <https://arstechnica.com/tech-policy/2019/05/how-qualcomm-shook-down-the-cel…>: Qualcomm's first weapon against competitors: patent licensing terms requiring customers to pay a royalty on every phone sold—not just phones that contained Qualcomm's wireless chips. Sound familiar? Judge Koh draws a direct parallel to licensing behavior that got Microsoft in legal trouble in the 1990s. Microsoft would offer PC makers a discount if they agreed to pay Microsoft a licensing fee for every PC sold—whether or not the PC shipped with a copy of MS-DOS. This effectively meant that a PC maker had to pay twice if it shipped a PC running a non-Microsoft operating system. There’s a lot more--the article reads like a catalogue of gangster-like tactics. All of which is perfectly all right under the US interpretation of “Free Enterprise”, of course ... Also, reading the details of how Qualcomm managed to sabotage Intel’s efforts to develop 5G chips, it seems to me that Qualcomm is directly responsible for the situation today where US companies are lagging behind Chinese ones like Huawei in 5G capability.

GPT-3 Raises Complex Questions for Philosophy and Policy
by Lawrence D'Oliveiro 14 Aug '20

14 Aug '20

From <https://freedom-to-tinker.com/2020/08/13/gpt-3-raises-complex-questions-for…>: GPT-3, a powerful, 175 billion parameter language model developed recently by OpenAI, has been galvanizing public debate and controversy ... Why the hype? GPT-3 is unlike other natural language processing (NLP) systems, the latter of which often struggle with what comes comparatively easily to humans: performing entirely new language tasks based on a few simple instructions and examples. Instead, NLP systems usually have to be pre-trained on a large corpus of text, and then fine-tuned in order to successfully perform a specific task. GPT-3, by contrast, does not require fine tuning of this kind: it seems to be able to perform a whole range of tasks reasonably well, from producing fiction, poetry, and press releases to functioning code, and from music, jokes, and technical manuals, to “news articles which human evaluators have difficulty distinguishing from articles written by humans”. Also note this: ... GPT-3 has been trained on us—on a lot of things that we have said and written—and ends up reproducing just that, racial and gender bias included. OpenAI acknowledges this in their own paper on GPT-3,where they contrast the biased words GPT-3 used most frequently to describe men and women, following prompts like “He was very…” and “She would be described as…”. The results aren’t great. For men? Lazy. Large. Fantastic. Eccentric. Stable. Protect. Survive. For women? Bubbly, naughty, easy-going, petite, pregnant, gorgeous.

Mozilla Extends its Google Search Deal
by Peter Reutemann 13 Aug '20

13 Aug '20

'Mozilla and Google have extended their search deal for another three years, news outlet ZDNet reported Wednesday, citing sources familiar with thee matter. Mozilla confirmed the news. From a report: The new search deal will ensure Google remains the default search engine provider inside the Firefox browser until 2023 at an estimated price tag of around $400 million to $450 million per year. Mozilla officials are expected to announce the search deal's extension later this fall, in November, when the organization is scheduled to disclose its 2019 financial figures. Terms of the new deal were leaked to this reporter after Mozilla announced plans to lay off more than 250 employees on Wednesday in a move that had many users fearing for the browser maker's future, as Mozilla's current Google search deal was scheduled to expire at the end of the year. However, several sources have confirmed that the organization is sound financially, and the layoffs were part of a restructuring of its core business, with Mozilla moving away from its current role of internet standards steward and experimental approach to its product catalog to more commercially-viable offerings that generate revenues on their own.' -- source: https://tech.slashdot.org/story/20/08/13/0012243 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 today launched ChromeOS.dev, a new site that aims to help developers get started with building Android apps for the company's Linux-based operating system. With today's update, Google is also making it easier to build and test Android applications on Chromebooks. From a report: The new ChromeOS.dev site, which is available in English and Spanish for now, is meant to "help developers maximize their capabilities on the platform through technical resources/tutorials, product announcements, code samples and more," a Google spokesperson told us. As Google notes in today's announcement, in the last quarter, Chromebook unit sales were up 127% year-over-year in the last quarter, compared to 40% for notebook sales in general. To help Android developers do all of their work on a Chromebook if they so desire, Google now offers the full Android Emulator on Chrome OS to test apps right on their Chromebooks. The team also made deploying apps on Chrome OS (M81 and newer) much easier. Developers can now deploy and test apps directly without having to use developer mode or connect devices via USB.' -- source: https://developers.slashdot.org/story/20/08/12/193214 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/

TikTok Tracked User Data Using Tactic Banned By Google
by Peter Reutemann 12 Aug '20

12 Aug '20

'TikTok skirted a privacy safeguard in Google's Android operating system to collect unique identifiers from millions of mobile devices, data that allows the app to track users online without allowing them to opt out, a Wall Street Journal analysis has found. The tactic, which experts in mobile-phone security said was concealed through an unusual added layer of encryption, appears to have violated Google policies limiting how apps track people and wasn't disclosed to TikTok users. TikTok ended the practice in November, the Journal's testing showed. The identifiers collected by TikTok, called MAC addresses, are most commonly used for advertising purposes. The White House has said it is worried that users' data could be obtained by the Chinese government and used to build detailed dossiers on individuals for blackmail or espionage. In a statement, a spokesperson said the company is "committed to protecting the privacy and safety of the TikTok community. Like our peers, we constantly update our app to keep up with evolving security challenges." The company said "the current version of TikTok does not collect MAC addresses."' -- source: https://yro.slashdot.org/story/20/08/11/2120246 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/

Android is Becoming a Worldwide Earthquake Detection Network
by Peter Reutemann 12 Aug '20

12 Aug '20

'Google is creating a worldwide, Android phone-powered earthquake alert system. The first part of that system is rolling out today. If you opt in, the accelerometer in your Android phone will become one data point for an algorithm designed to detect earthquakes. Eventually, that system will automatically send warnings to people who could be impacted. From a report: It's a feature made possible through Google's strengths: the staggering numbers of Android phones around the world and clever use of algorithms on big data. As with its collaboration with Apple on exposure tracing and other Android features like car crash detection and emergency location services, it shows that there are untapped ways that smartphones could be used for something more important than doomscrolling. Google is rolling out the system in small stages. First, Google is partnering with the United States Geological Survey and the California Office of Emergency Services to send the agencies' earthquake alerts to Android users in that state. Those alerts are generated by the already-existing ShakeAlert system, which uses data generated by traditional seismometer' -- source: https://tech.slashdot.org/story/20/08/11/1440235 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/

China Blocking ESNI Connections
by Lawrence D'Oliveiro 11 Aug '20

11 Aug '20

TLS 1.3 (the latest version of the protocol used for “HTTPS” connections) adds a feature called “Encrypted Server Name Indication” (ESNI). This removes a loophole where the initial exchange, in which the browser indicates to the server which (of possibly many) virtual host names it is trying to connect to, is sent unencrypted. Reports <https://www.theregister.com/2020/08/11/china_blocking_tls_1_3_esni/> are saying that the Great Firewall of China is trying to block all such connection attempts, just in case any of them happen to be to “banned” sites. However, it is (currently) possible to manipulate the packet stream in such a way as to fool this filtering, so the connection can go through.

Snapdragon chip flaws put >1 billion Android phones at risk of data theft
by Peter Reutemann 10 Aug '20

10 Aug '20

'A billion or more Android devices are vulnerable to hacks that can turn them into spying tools by exploiting more than 400 vulnerabilities in Qualcomm’s Snapdragon chip, researchers reported this week. The vulnerabilities can be exploited when a target downloads a video or other content that’s rendered by the chip. Targets can also be attacked by installing malicious apps that require no permissions at all. >From there, attackers can monitor locations and listen to nearby audio in real time and exfiltrate photos and videos. Exploits also make it possible to render the phone completely unresponsive. Infections can be hidden from the operating system in a way that makes disinfecting difficult. Snapdragon is what’s known as a system on a chip that provides a host of components, such as a CPU and a graphics processor. One of the functions, known as digital signal processing, or DSP, tackles a variety of tasks, including charging abilities and video, audio, augmented reality, and other multimedia functions. Phone makers can also use DSPs to run dedicated apps that enable custom features.' -- source: https://arstechnica.com/information-technology/2020/08/snapdragon-chip-flaw… 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/

Researcher Discovers New 'HTTP Request Smuggling Attack' Variants
by Peter Reutemann 10 Aug '20

10 Aug '20

'Some scary new variants of "HTTP request smuggling" have been discovered by Amit Klein, VP of security research at SafeBreach, reports Security Week: Specifically, an HTTP request smuggling attack, which can be launched remotely over the internet, can allow a hacker to bypass security controls, gain access to sensitive data, and compromise other users of the targeted app. While the attack method has been known for more than a decade, it still hasn't been fully mitigated. Klein has managed to identify five new attack variants and he has released proof-of-concept (PoC) exploits. He demonstrated his findings using the Abyss X1 web server from Aprelium and the Squid caching and forwarding HTTP web proxy. The developers of Abyss and Squid have been notified of the vulnerabilities exploited by Klein during his research, and they have released patches and mitigations. One of the attacks bypasses the OWASP ModSecurity Core Rule Set (CRS), which provides generic attack detection rules for ModSecurity or other web application firewalls. OWASP has also released fixes after being notified. Klein told SecurityWeek ahead of his talk on HTTP request smuggling at the Black Hat conference that an attacker needs to find combinations of web servers and proxy servers with "matching" vulnerabilities in order to launch an attack, which makes it difficult to determine exactly how many servers are impacted. However, an attacker can simply try to launch an attack to determine if a system is vulnerable. "The attack is not demanding resource-wise, so there's no downside to simply trying it," Klein said. In his research, he demonstrated a web cache poisoning attack, in which the attacker forces the proxy server to cache the content of one URL for a request of a different URL. He says attacks can be launched en-masse through a proxy server against multiple different web servers or against multiple proxy servers... While there haven't been any reports of HTTP request smuggling being used in the wild, Klein has pointed out that attacks may have been launched but were not detected by the target.' -- source: https://it.slashdot.org/story/20/08/09/0047219 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: Linux 5.8 "One of our Biggest Releases of All Time"
by Peter Reutemann 10 Aug '20

'This week saw the release Linux 5.8, which Linus Torvalds called "one of our biggest releases of all time," reports TechRepublic: The new version of the Linux kernel brings a number of updates to Linux 5.7 spanning security, core components, drivers, memory management, networking and improvements to the kernel's design, amongst others. This includes updates for Microsoft's Hyper-V virtualization platform, Intel Tiger Lake Thunderbolt support, improvements to Microsoft's exFAT file system, and support for newer Intel and ARM chips. Torvalds said the kernel had received over 15,000 merge requests and that around 20% of all the files in the kernel source repository had been modified. "That's really a fairly big percentage, and while some of it is scripted, on the whole it's really just the same pattern: 5.8 has simply seen a lot of development," Torvalds said. Translated into numbers, Linux 5.8 includes over 800,000 new lines and over 14,000 changed files. It also received one of the biggest number of merge requests during its merge window — over 14,000 non-merge commits and more than 15,000 including merges, according to Torvalds. "5.8 looks big.

Scientists Rename Human Genes To Stop Microsoft Excel From Misreading Them as Dates
by Peter Reutemann 08 Aug '20

08 Aug '20

'There are tens of thousands of genes in the human genome: minuscule twists of DNA and RNA that combine to express all of the traits and characteristics that make each of us unique. Each gene is given a name and alphanumeric code, known as a symbol, which scientists use to coordinate research. But over the past year or so, some 27 human genes have been renamed, all because Microsoft Excel kept misreading their symbols as dates. From a report: The problem isn't as unexpected as it first sounds. Excel is a behemoth in the spreadsheet world and is regularly used by scientists to track their work and even conduct clinical trials. But its default settings were designed with more mundane applications in mind, so when a user inputs a gene's alphanumeric symbol into a spreadsheet, like MARCH1 -- short for "Membrane Associated Ring-CH-Type Finger 1" -- Excel converts that into a date: 1-Mar. This is extremely frustrating, even dangerous, corrupting data that scientists have to sort through by hand to restore. It's also surprisingly widespread and affects even peer-reviewed scientific work. One study from 2016 examined genetic data shared alongside 3,597 published papers and found that roughly one-fifth had been affected by Excel errors.' -- source: https://science.slashdot.org/story/20/08/06/147226 This auto-interpreting and getting things wrong has always annoyed me about Excel and other spreadsheet applications.

The Next Step In SSD Evolution: NVMe Zoned Namespaces Explained
by Peter Reutemann 07 Aug '20

07 Aug '20

'In June we saw an update to the NVMe standard. The update defines a software interface to assist in actually reading and writing to the drives in a way to which SSDs and NAND flash actually works. Instead of emulating the traditional block device model that SSDs inherited from hard drives and earlier storage technologies, the new NVMe Zoned Namespaces optional feature allows SSDs to implement a different storage abstraction over flash memory. This is quite similar to the extensions SAS and SATA have added to accommodate Shingled Magnetic Recording (SMR) hard drives, with a few extras for SSDs. 'Zoned' SSDs with this new feature can offer better performance than regular SSDs, with less overprovisioning and less DRAM. The downside is that applications and operating systems have to be updated to support zoned storage, but that work is well underway. The NVMe Zoned Namespaces (ZNS) specification has been ratified and published as a Technical Proposal. It builds on top of the current NVMe 1.4a specification, in preparation for NVMe 2.0. The upcoming NVMe 2.0 specification will incorporate all the approved Technical Proposals, but also reorganize that same functionality into multiple smaller component documents: a base specification (one for each command set of block, zoned, key-value, and potentially more in the future), and separate specifications for each transport protocol (PCIe, RDMA, TCP). The standardization of Zoned Namespaces clears the way for broader commercialization and adoption of this technology, which so far has been held back by vendor-specific zoned storage interfaces and very limited hardware choices.

Can Killing Cookies Save Journalism?
by Peter Reutemann 07 Aug '20

07 Aug '20

'In May 2018, as the European Union’s landmark privacy law, the General Data Protection Regulation, went into effect, the main Dutch public broadcaster set in motion a grand experiment. The leadership at Nederlandse Publieke Omroep—essentially the BBC of the Netherlands—interpreted the law strictly, deciding that visitors to any of its websites would now be prompted to opt in or out of cookies, the tracking technology that enables personalized ads based on someone’s browsing history. And, unlike with most companies, who assume that anyone who skips past a privacy notice is OK with tracking, any NPO visitor who clicked past the obtrusive consent screen without making a choice would be opted out by default. The results weren’t terribly surprising: 90 percent of users opted out. Here is where the ad tech industry would have predicted calamity. A study performed by Google last year, for example, concluded that disabling cookies reduced publisher revenue by more than 50 percent. (Research by an independent team of economists, however, pegged the cookie premium at only 4 percent. Needless to say, there were methodological differences.) If the Google study was right, then NPO should have been heading for financial disaster. The opposite turned out to be true. Instead, the company found that ads served to users who opted out of cookies were bringing in as much or more money as ads served to users who opted in. The results were so strong that as of January 2020, NPO simply got rid of advertising cookies altogether. And rather than decline, its digital revenue is dramatically up, even after the economic shock of the coronavirus pandemic.' -- source: https://www.wired.com/story/can-killing-cookies-save-journalism/ 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 for Android May Soon Send Notifications Reminding You To Use Chrome
by Peter Reutemann 06 Aug '20

06 Aug '20

'For years now, Google Chrome has been an absolute dominant force in the world of web browsers, but since the relaunch of Microsoft Edge based on Google's Chromium, that position has been challenged. Now, Google is preparing to drive more Android owners back to using Chrome through targeted notifications. Over the admittedly brief history of the Internet, there have been a number of fierce competitions, commonly called "browser wars," between companies, in an effort to get more people to use their particular web browser. Mozilla and Netscape waged war against Internet Explorer, and Chrome fought and won against Firefox. Most recently, Microsoft Edge and Samsung Internet have begun to wage war against Chrome on desktop and Android respectively. Now, we've found that Google is preparing to try and win back some of those who have left Chrome for other browsers, starting on Android. Based on our reading of a series of code changes, we believe Google Chrome for Android will send you a notification if you haven't used Chrome in a while.' -- source: https://it.slashdot.org/story/20/08/05/2022204 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/

Hackers Could Use IoT Botnets To Manipulate Energy Markets
by Peter Reutemann 06 Aug '20

06 Aug '20

'Wired: At the Black Hat security conference on Wednesday, [researchers at the Georgia Institute of Technology] will present their findings, which suggest that high-wattage IoT botnets -- made up of power-guzzling devices like air conditioners, car chargers, and smart thermostats -- could be deployed strategically to increase demand at certain times in any of the nine private energy markets around the US. A savvy attacker, they say, would be able to stealthily force price fluctuations in the service of profit, chaos, or both. The researchers used real, publicly available data from the New York and California markets between May 2018 and May 2019 to study fluctuations in both the "day-ahead market" that forecasts demand and the "real-time market," in which buyers and sellers correct for forecasting errors and unpredictable events like natural disasters. By modeling how much power various hypothetical high-wattage IoT botnets could draw, and crunching the market data, the researchers devised two types of potential attacks that would alter energy pricing. They also figured out how far hackers would be able to push their attacks without the malicious activity raising red flags. "Our basic assumption is that we have access to a high-wattage IoT botnet," says Tohid Shekari, a PhD candidate at the Georgia Institute of Technology who contributed to the research, along with fellow PhD candidate Celine Irvine and professor Raheem Beyah. "In our scenarios, attacker one is a market player; he's basically trying to maximize his own profit. Attacker two is a nation-state actor who can cause financial damage to market players as part of a trade war or cold war. The basic part of either attack is to look at price-load sensitivity. If we change demand by 1 percent, how much is the price going to change as a result of that? You want to optimize the attack to maximize the gain or damage." An attacker could use their botnet's power to increase demand, for instance, when other entities are betting it will be low. Or they could bet that demand will go up at a certain time with certainty that they can make that happen. "The researchers caution that, based on their analysis, much smaller demand fluctuations than you might expect could affect pricing, and that it would take as few as 50,000 infected devices to pull off an impactful attack," the report adds. "Consumers whose devices are unwittingly conscripted into a high-wattage botnet would also be unlikely to notice anything amiss; attackers could intentionally turn on devices to pull power late at night or while people are likely to be out of the house. [...] The researchers calculated that market manipulation campaigns would cause, at most, a 7 percent increase in consumers' home electric bills, likely low enough to go unnoticed." The researchers say market manipulators could take home as much as $245 million a year, and cause as much as $350 million per year in economic damage.' -- source: https://hardware.slashdot.org/story/20/08/04/2213253 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/

LastPass Will Warn You If Your Passwords Show Up On the Dark Web
by Peter Reutemann 06 Aug '20

06 Aug '20

'LastPass is updating its Security Dashboard with a feature that provides an overview of all your accounts, highlighting any passwords that could pose a security risk. The password manager is also introducing dark web monitoring, although it will require you to be a paid LastPass subscriber. Engadget reports: If you already use LastPass and the Security Dashboard sounds familiar, it's because it builds on the Security Challenge functionality LastPass developer LogMeIn added in 2010. As before, grading is a major aspect of the interface. When you first navigate to the Security Dashboard, you'll see a score of all your logins, followed by a breakdown of passwords that are either old, inactive, weak or reused. You can click or tap on a problematic password to change it, and LastPass will automatically take you to the webpage where you can update your login information. LogMeIn hasn't changed how the app calculates the overall score it gives to each user. But one significant improvement the Security Dashboard brings over the Security Challenge is that you don't need to manually run it each time you want to see the security of your online accounts. The score and steps you can take to improve your online security are there each time you visit that part of the software's interface. With today's update, LogMeIn is also introducing dark web monitoring. When you enable the feature, LastPass will proactively check your online accounts against Enzoic's compromised credentials database. If it detects an issue, it will notify you through both email and the app. Dark web monitoring is available to LastPass Premium, Family and Business subscribers. The dashboard, by contrast, is available to all LastPass users.

Hacker Leaks Passwords For 900+ Enterprise VPN Servers
by Peter Reutemann 06 Aug '20

06 Aug '20

'A hacker has published today a list of plaintext usernames and passwords, along with IP addresses for more than 900 Pulse Secure VPN enterprise servers. ZDNet reports: According to a review, the list includes: IP addresses of Pulse Secure VPN servers, Pulse Secure VPN server firmware version, SSH keys for each server, a list of all local users and their password hashes, admin account details, last VPN logins (including usernames and cleartext passwords), and VPN session cookies. Bank Security, a threat intelligence analyst specialized in financial crime [...] noted that all the Pulse Secure VPN servers included in the list were running a firmware version vulnerable to the CVE-2019-11510 vulnerability. Bank Security believes that the hacker who compiled this list scanned the entire internet IPv4 address space for Pulse Secure VPN servers, used an exploit for the CVE-2019-11510 vulnerability to gain access to systems, dump server details (including usernames and passwords), and then collected all the information in one central repository. Making matters worse, the list has been shared on a hacker forum that is frequented by multiple ransomware gangs. For example, the REvil (Sodinokibi), NetWalker, Lockbit, Avaddonm, Makop, and Exorcist ransomware gangs have threads on the same forum, and use it to recruit members (developers) and affiliates (customers). Many of these gangs perform intrusions into corporate networks by leveraging network edge devices like Pulse Secure VPN servers, and then deploy their ransomware payload and demand huge ransom demands. As Bank Security told ZDNet, companies have to patch their Pulse Secure VPNs and change passwords with the utmost urgency.

Twitter Says Android Security Bug Gave Access To Direct Messages
by Peter Reutemann 06 Aug '20

06 Aug '20

'Twitter says a security bug may have exposed the private direct messages of its Android app users, but said that there was no evidence that the vulnerability was ever exploited. From a report: The bug could have allowed a malicious Android app running on the same device to siphon off a user's direct messages stored in the Twitter app by bypassing Android's in-built data permissions. But, Twitter said that the bug only worked on Android 8 (Oreo) and Android 9 (Pie), and has since been fixed. A Twitter spokesperson told TechCrunch that the bug was reported by a security researcher "a few weeks ago" through HackerOne, which Twitter uses for its bug bounty program. "Since then, we have been working to keep accounts secure," said the spokesperson. "Now that the issue has been fixed, we're letting people know." Twitter said it waited to let its users know in order to prevent someone from learning about the issue and taking advantage of it before it was fixed.' -- source: https://yro.slashdot.org/story/20/08/05/1728253 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/

Cambridge University Goes Microsoft
by Lawrence D'Oliveiro 05 Aug '20

05 Aug '20

Cambridge University, one of the pioneering centres of computer science research (since 1937), is retiring its in-house Hermes e-mail system in favour of moving completely to Microsoft Exchange Online <https://www.theregister.com/2020/08/04/cambridge_uni_decommissioning_hermes…>. Admin David McBride argues that Microsoft “does not implement IETF standards – at least not competently". In particular, he said: "Its IMAP service implementation is sufficiently poor as to lose data in practice, its mail handling has been seen to violate RFC MUST assertions that causes cryptographic email signatures to be rendered invalid, and it has even sometimes generated outbound email that contains invalid MIME data." He added: "Email services that do not competently support IETF standards, such as SMTP, IMAP, MIME and the like, present significant interoperability challenges and will risk leaving us locked in to using a single vendor." According to the info here <https://fanf2.user.srcf.net/photos.html> (linked from a reader comment), Hermes is not some kind of homebrew proprietary system; it is built on well-known open-source components such as Exim and Cyrus.

Windows 10: HOSTS File Blocking Telemetry Is Now Flagged As a Risk

'Starting at the end of July, Microsoft has begun detecting HOSTS files that block Windows 10 telemetry servers as a 'Severe' security risk. Windows 10 users are reporting that Windows Defender had started detectingmodified HOSTS files as a 'SettingsModifier:Win32/HostsFileHijack' threat. So it seems that Microsoft had recently updated their Microsoft Defender definitions to detect when their servers were added to the HOSTS file. Users who utilize HOSTS files to block Windows 10 telemetry suddenly caused them to see the HOSTS file hijack detection. Users who intentionally modify their HOSTS file can allow this 'threat,' but it may enable all HOSTS modifications, even malicious ones, going forward.' -- source: https://tech.slashdot.org/story/20/08/04/143248 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/

Android's Nearby Share' File Sharing Feature is Finally Launching
by Peter Reutemann 05 Aug '20

05 Aug '20

'It will finally be slightly easier to share files, images, links, and other content between Android devices. Google is launching a new Android feature called "Nearby Share" that enables direct sharing between any device running Android 6 and up. Nearby Share is already available on some Pixel and Samsung phones, and Google says it'll arrive on other devices "over the next few weeks." From a report: Nearby Share works very much like Apple's AirDrop feature for the iPhone: you simply select the Nearby Share button on the share menu and then wait for a nearby phone to appear. Then whatever thing you're sharing is sent directly over your transfer method of choice to the other phone. As with AirDrop, you can set your preferred visibility for Nearby Share to different levels of contacts: all, some, or stay hidden. Google says it's even possible to "send and receive files anonymously." (Welcome to AirSlothing, Android users.) Nearby Share also shares files directly via whatever method your two phones deem is fastest: "Bluetooth, Bluetooth Low Energy, WebRTC or peer-to-peer Wi-Fi," which Google says should allow it to work offline.' -- source: https://tech.slashdot.org/story/20/08/04/1935221 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/

Decades-Old Email Flaws Could Let Attackers Mask Their Identities
by Peter Reutemann 05 Aug '20

05 Aug '20

'At the Black Hat security conference on Thursday, researchers will present "darn subtle" flaws in industry-wide protections used to ensure that emails come from the address they claim to. From a report: The study looked at the big three protocols used in email sender authentication -- Sender Policy Framework (SPF), Domain Keys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting and Conformance (DMARC) -- and found 18 instances of what the researchers call "evasion exploits." The vulnerabilities don't stem from the protocols themselves, but from how different email services and client applications implement them. Attackers could use these loopholes to make spearphishing attacks even harder to detect. "I think I'm a savvy, educated user and the reality is, no, that's actually not enough," says Vern Paxson, cofounder of the network traffic analysis firm Corelight and a researcher at the University of California, Berkeley, who worked on the study along with Jianjun Chen, a postdoctoral researcher at the International Computer Science Institute, and Jian Jiang, senior director of engineering at Shape Security. "Even users who are pretty savvy are going to look at the indicators that Gmail or Hotmail or others provide and be fooled," Paxson says. Think about when you hand a friend a birthday card at their party. You probably only write their first name on the outside of the envelope, and maybe underline it or draw a heart. If you mail that letter instead, though, you need the recipient's full name and detailed address, a stamp, and ultimately a postmark with a date on it. Sending email across the internet works similarly. Though email services only require you to fill out the "To" and "Subject" fields, there's a whole list of more detailed information getting filled out behind the scenes. Those industry-standard "headers," as they're known, include date and time sent and received, language, a unique identifier called a Message-ID, and routing information.' -- source: https://it.slashdot.org/story/20/08/04/2037238 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 and Edge Rise In Popularity. Firefox, Opera, and Safari Drop.
by Peter Reutemann 04 Aug '20

04 Aug '20

'July's statistics from web analytics firm Net Applications showed continuing changes in the most frequently-used web browsers. Softpedia reports: Last month, Google Chrome increased its market share from 70.19% to 71.00%, while Microsoft Edge jumped from 8.07% to 8.46%... The migration to the Chromium engine allowed Microsoft to turn Edge into a cross-platform browser, and this is one of the reasons that contributed to the growth of the new app. Edge is now available not only on Windows 10, but also on Windows 7, Windows 8, Windows 8.1, and even macOS. At the same time, Microsoft is also working on a Linux version of the browser, and a preview build is expected by the end of the year. But what made Microsoft Edge the second most-used desktop browser out there so fast after the switch to Chromium is definitely Microsoft offering it as the default browser in Windows 10. But what about Firefox? And Opera, and Apple's Safari? Computerworld reports: A decade ago, Mozilla's browser may have dreamed of upsetting the then-order of things, taking its April 2010 share of 25.1% and parlaying it into victory over IE — down to 61.2% by then... But that was Firefox's peak. At the end of July, Firefox stood at 7.3%, down three-tenths of a percentage point from the previous month... Firefox let its second-place spot (far, far behind Chrome) slip away in March, when Edge snatched it. That did not change in July. The gap between the two more than doubled, in fact, to 1.2 points. On almost every browser share metric, Firefox is in trouble... Since the end of January, Firefox has been stuck in the 7s; for the eight months before that, it was mired in the 8s; and between May 2018 and March 2019, Firefox floundered in the 9s. The trend is crystal clear... Elsewhere in Net Applications' numbers, Apple's Safari plunged to 3%, a loss of six-tenths of a point, its lowest mark since late 2008. Opera software's Opera also took a dive, ending July at 0.8%, a decline of three-tenths of a point. Those numbers have to be frightening to both those browsers' makers.' -- source: https://news.slashdot.org/story/20/08/03/028217 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/

Package management mistake borking some Ubuntu machines running WireGuard
by Eric Light 04 Aug '20

04 Aug '20

Morning folks! For those who watch WireGuard, Jason Donenfeld is giving the Canonical kernel team a damn roasting after they bungled a Provides statement in about half of their Linux kernel manifests... which borks certain systems running WireGuard. For example, systems with the linux-image-oem kernel will try to install the linux-image-gke kernel (meant for the Google Kubernetes Engine), in order to receive the wireguard-modules package, leading to Proper Breakage. Donenfeld: "I'll note that this is at least the third time Canonical has forgotten the "Provides:" line for kernel packages. I'd highly recommend they put some time into double checking their procedures. [...] Usually things go quite a bit better with the WireGuard side of things, but this seems pretty par for the course with _Ubuntu_ and Canonical's kernel team. We've had perpetual issues over the last 6 months with getting Canonical to release high quality packages in a timely manner. A pretty large portion of my time is spent dealing with these bugs and Ubuntu in general." Looks like Canonical's kernel packaging team are already working on it, after Jason Donenfeld escalated a bug report earlier this morning.

Hi all, Apologies for being slightly off-topic. Does anyone know of a computer repairer in/around Hamilton, who can do board-level troubleshooting and repair on laptops, without having to "send it to Auckland"? I've got a Gigabyte i7 laptop which became unable to charge its battery a couple of years ago. I was able to run it plugged into the mains since then. But just now, it won't even start up at all. I'd like someone to do some quick tests to determine if it's a feasible repair and, if so, give a cost estimate. Oh, but it was running Ubuntu, so not completely off-topic ;) All suggestions appreciated Cheers David

Bug In Grub2 Breaks Secure Boot (Yawn)
by Lawrence D'Oliveiro 30 Jul '20

30 Jul '20

Seems a vulnerability has been found in everyone’s favourite bootloader <https://arstechnica.com/information-technology/2020/07/new-flaw-neuters-sec…> which allows a bypass of the “Secure Boot” mechanism in modern UEFI-based machines. But given that so many other bypasses already exist, nobody seems especially worried about this. For example, the article references an attempt by Microsoft to revoke the certification of (an obsolete version of) a secure bootloader from Kaspersky Lab with a vulnerability in it; the revocation caused so many headaches for users that it had to be rolled back.

Hackers Stole GitHub and GitLab OAuth Tokens From Git Analytics Firm Waydev
by Peter Reutemann 28 Jul '20

'Waydev, an analytics platform used by software companies, has disclosed a security breach that occurred earlier this month. From a report: The company says that hackers broke into its platform and stole GitHub and GitLab OAuth tokens from its internal database. Waydev, a San Francisco-based company, runs a platform that can be used to track software engineers' work output by analyzing Git-based codebases. To do this, Waydev runs a special app listed on the GitHub and GitLab app stores. When users install the app, Waydev receives an OAuth token that it can use to access its customers' GitHub or GitLab projects. Waydev stores this token in its database and uses it on a daily basis to generate analytical reports for its customers. Waydev CEO and co-founder Alex Circei told ZDNet today in a phone call that hackers used a blind SQL injection vulnerability to gain access to its database, from where they stole GitHub and GitLab OAuth tokens. The hackers then used some of these tokens to pivot to other companies' codebases and gain access to their source code projects.' -- source: https://tech.slashdot.org/story/20/07/27/1918237 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/

Popular Chinese-Made Drone Is Found To Have Security Weakness
by Peter Reutemann 24 Jul '20

24 Jul '20

'Cybersecurity researchers revealed on Thursday a newfound vulnerability in an app that controls the world's most popular consumer drones, threatening to intensify the growing tensions between China and the United States. From a report: In two reports, the researchers contended that an app on Google's Android operating system that powers drones made by China-based Da Jiang Innovations, or DJI, collects large amounts of personal information that could be exploited by the Beijing government. Hundreds of thousands of customers across the world use the app to pilot their rotor-powered, camera-mounted aircraft. The world's largest maker of commercial drones, DJI has found itself increasingly in the cross hairs of the United States government, as have other successful Chinese companies. The Pentagon has banned the use of its drones, and in January the Interior Department decided to continue grounding its fleet of the company's drones over security fears. DJI said the decision was about politics, not software vulnerabilities. For months, U.S. government officials have stepped up warnings about the Chinese government's potentially exploiting weaknesses in tech products to force companies there to give up information about American users. Chinese companies must comply with any government request to turn over data, according to American officials. "Every Chinese technology company is required by Chinese law to provide information they obtain, or information stored on their networks, to Chinese authorities if requested to do so," said William R. Evanina, director of the National Counterintelligence and Security Center. "All Americans should be concerned that their images, biometrics, locational and other data stored on Chinese apps must be turned over to China's state security apparatus." The drone vulnerability, said American officials, is the kind of security hole that worries Washington.' -- source: https://it.slashdot.org/story/20/07/23/1437214 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/

Fawkes: Protecting Privacy against Unauthorized Deep Learning Models
by Lawrence D'Oliveiro 23 Jul '20

23 Jul '20

This paper <http://people.cs.uchicago.edu/%7Eravenben/publications/abstracts/fawkes-use…>, presented at USENIX Security 2020, discusses techniques for allowing you to continue to share images of yourself online while making them resistant to automated exploitation by “deep-learning” facial-recognition software. The researchers found that they could make subtle distortions to facial images, imperceptible to the human eye, that would severely confuse recognition services from major providers like Microsoft and Amazon.

We test Mozilla’s new Wireguard-based $5/mo VPN service
by Peter Reutemann 23 Jul '20

23 Jul '20

'Mozilla, the open source company best known for the Firefox Web browser, made its VPN service generally available in the United States this month. The cross-platform VPN is based on Wireguard and delivered in partnership with well-known and especially techie-friendly VPN provider Mullvad. Mullvad itself was, to the best of our knowledge, the first publicly available VPN provider to offer Wireguard support back in 2017. The Mozilla VPN service costs $4.95 per month and offers server endpoints in 30-plus countries. It currently has VPN clients available for Windows 10, Android, and iOS—but users of other operating systems, such as MacOS and Linux, are going to have to wait. Mozilla says that support for MacOS and Linux is coming soon—but unfortunately, even if you're an advanced user who understands Wireguard configs, you can't just roll your own connection now. The service authenticates via Firefox cloud account. When you sign up for a Mozilla VPN subscription, you'll be asked to create a Firefox account if you don't already have one. The Firefox account is an SSO (Single Sign On) service which uses oauth2, much like a Google account—but it's not tied to a Google account, so even if you sign up using a Gmail address tied to an Android device, that device won't be automatically logged in. Aside from the Firefox-based oauth2 integration, Mozilla's VPN appears to effectively be a Mullvad VPN, with a different client application and different billing entity. It is a bit less expensive through Mozilla, though—Mullvad costs €5 per month. This makes Mozilla's offering about $0.80 per month cheaper, at current exchange rates.' -- source: https://arstechnica.com/gadgets/2020/07/we-test-mozillas-new-wireguard-base… 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 Detection Still Works in Chrome Despite Promise To Fix
by Peter Reutemann 22 Jul '20

22 Jul '20

'Websites are still capable of detecting when a visitor is using Chrome's incognito (private browsing) mode, despite Google's efforts last year to disrupt the practice. From a report: It is still possible to detect incognito mode in Chrome, and all the other Chromium-based browsers, such as Edge, Opera, Vivaldi, and Brave, all of which share the core of Chrome's codebase. Furthermore, developers have taken the scripts shared last year and have expanded support to non-Chrome browsers, such as Firefox and Safari, allowing sites to block users in incognito mode across the board. Currently, there is no deadline for a new Chrome update to block incognito mode detections, however, today, Google might be interested more than ever in fixing this issue' -- source: https://yro.slashdot.org/story/20/06/04/1857211 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/

SUSE Releases Major Linux Update
by Peter Reutemann 22 Jul '20

22 Jul '20

'SUSE has released the next versions of its flagship operating system, SUSE Linux Enterprise (SLE) 15 Service Pack 2 and its latest infrastructure management program, SUSE Manager 4.1. ZDNet reports: SLE 15 SP2 is available on the x86-64, Arm, IBM POWER, IBM Z, and LinuxONE hardware architectures. This new Linux server edition is based on the Linux 5.3 kernel. This new kernel release includes upstream features such as utilization clamping support in the task scheduler, and power-efficient userspace waiting. Other new and noteworthy features include: - Support for migration from openSUSE Leap to SUSE Linux Enterprise Server (SLES). With this, you can try the free, community openSUSE Linux distro, and then, if you find it's a good choice for your business, upgrade to SLES. - Extended Package Search. By using the new Zypper, SUSE's command line package manager, command option -- zypper search-packages -- sysadmins can now search across all SUSE repositories, even unenabled ones. This makes it easier for administrators to find required software packages. - SLE Software Development Kit (SDK) is now integrated into SLE. Development packages are packaged alongside regular packages. - Python 3: SLE 15 offers full support for Python 3 development. SLE still supports Python 2 for the time being. - 389 Directory Server replaces OpenLDAP as the LDAP directory service. - Repository Mirroring Tool (RMT) replaces Subscription Management Tool (SMT). RMT allows mirroring SUSE repositories and custom repositories. You can then register systems directly with RMT. In environments with tightened security, RMT can also proxy other RMT servers. - Better business continuity with improved SLE Live Patching. SUSE claims Live Patching increases system uptime by up to 12 months. SLE Live Patching is also now available for IBM Z and LinuxONE mainframe architectures. As for SUSE Manager 4.1, this is an improved open-source infrastructure management and automation solution that lowers costs, identifies risk, enhances availability, and reduces complexity in edge, cloud, and data center environments. With SUSE Manager you can keep servers, VMs, containers, and clusters secure, healthy, compliant, and low maintenance whether in private, public, or hybrid cloud. That's especially important these days thanks to coronavirus pandemic IT staff disruptions. SUSE Manager 4.1 can also be used with the Salt DevOps program. Its vertical-market brother, SUSE Manager for Retail 4.1, is optimized and tailored specifically for retail. This release comes with enhancements for small store operations, enhanced offline capabilities and image management over Wi-Fi, and enhanced virtual machine management and monitoring capabilities. Simultaneously it can scale retail environments to tens of thousands of end-point devices and help modernize point-of-service rollouts.' -- source: https://linux.slashdot.org/story/20/07/21/2152237 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/

BadPower Attack Corrupts Fast Chargers To Melt or Set Your Device on Fire
by Peter Reutemann 21 Jul '20

21 Jul '20

'Chinese security researchers said they can alter the firmware of fast chargers to cause damage to connected (charging) systems, such as melt the components, or even set devices on fire. Iwastheone shares a report: The technique, named BadPower, was detailed last week in a report published by Xuanwu Lab, a research unit of Chinese tech giant Tencent. According to researchers, BadPower works by corrupting the firmware of fast chargers -- a new type of charger that was developed in the past few years to speed up charging times. A fast charger looks like any typical charger but works using special firmware. This firmware "talks" to a connected device and negotiates a charging speed, based on the device's capabilities. If a fast-charging feature is not supported, the fast charger delivers the standard 5V, but if the device can handle bigger inputs, the fast charger can deliver up to 12V, 20V, or even more, for faster charging speeds. The BadPower technique works by altering the default charging parameters to deliver more voltage than the receiving device can handle, which degrades and damages the receiver's components, as they heat up, bend, melt, or even burn.' -- source: https://tech.slashdot.org/story/20/07/20/1624200 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/

Could Pine64's Cheap Linux Smartphone Replace Your PC?
by Peter Reutemann 20 Jul '20

20 Jul '20

'TechRadar reports on Pine64's new "PinePhone Convergence Package" handset, calling it "a Linux desktop you can keep in your pocket" that can be used as a PC when plugged into an external display and a keyboard. The device costs just $199 and is aimed primarily at Linux enthusiasts. The PinePhone Linux smartphone is based on the Alpine Linux-based PostmarketOS that can be used both in smartphone and desktop modes... The main component that transforms the PinePhone into a PC-like device is its USB-C docking bar that features an HDMI display output, two USB Type-A connectors, and a 10/100Mb Ethernet port. The idea of using a smartphone with an external display and keyboard to run certain applications has not gained much traction neither with HP's Elite x3 Windows Phone 10 handset nor with Samsung's smartphones with its DeX software. Perhaps, since Linux community is generally more inclined to experiment with their gadgets (and their time), Pine64's PinePhone Convergence has a better chance to be actually used as a desktop by its owners.

'Mozilla VPN' Launches in Six Countries
by Peter Reutemann 20 Jul '20

20 Jul '20

'"Starting today, there's a VPN on the market from a company you trust," Mozilla announced Wednesday. Mozilla VPN is now officially available for Windows and Android in six countries: the U.S., Canada, the U.K., Singapore, Malaysia, and New Zealand, and it'll be coming to even more countries later this year, reports the Verge: The service is available for $4.99 a month, and, like other VPNs, it's designed to make your web-browsing more private and secure. As part of the move, the service is being rebranded from Firefox Private Network to Mozilla VPN, a change that was announced last month. Mozilla argues that its VPN service has a couple of advantages over its many competitors. It says it should offer a faster browsing experience in many cases because it's based on a protocol with less than a third of the lines of code of an average VPN service provider. The company is also banking on the reputation it's built up with its privacy-focused browser, and it adds that it only collects the information it needs to run a service and doesn't keep user data logs. The VPN's launch follows beta trials in the US, which also included tests of a VPN built directly into the Firefox browser. Last month, Mozilla announced that it would be testing asking users to pay $2.99 a month for unlimited usage of the extension, which is designed to mask your traffic within the browser rather than at a system-wide level.' -- source: https://tech.slashdot.org/story/20/07/19/0437230 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/

VPN With 'Strict No-Logs Policy' Exposed Millions of User Log Files

User of both UFO VPN free and paid services are affected by the data breach which was discovered by the security research team at Comparitech. Despite the Hong Kong-based VPN provider claiming to have a "strict no-logs policy" and that any data collected is anonymized, Comparitech says that "based on the contents of the database, users' information does not appear to be anonymous at all." A total of 894GB of data was exposed, and the API access records and user logs included: Account passwords in plain text; VPN session secrets and tokens; IP addresses of both user devices and the VPN servers they connected to; Connection timestamps; Geo-tags; Device and OS characteristics; and URLs that appear to be domains from which advertisements are injected into free users' web browsers.

LibreOffice Ructions
by Lawrence D'Oliveiro 17 Jul '20

From <https://www.theregister.com/2020/07/16/libreoffice_ecosystem_beyond_utterly…>: Michael Meeks: “Words fail me to express how beyond-utterly-broken the existing TDF / desktop model is for the ecosystem around selling desktop LibreOffice.” As you may know, LibreOffice is overseen by The Document Foundation, which is a charity registered in Germany. And it currently has about €1.5 million in the bank. However, owing to peculiarities of German law (or maybe just the way they are interpreting it), none of that money is actually allowed to be spent on software development.

The Pros & Cons Of Virtual Meetings
by Lawrence D'Oliveiro 17 Jul '20

17 Jul '20

<https://www.theregister.com/2020/07/16/virtual_internet_governance_meeting_…>: The move to virtual meetings among internet governance bodies has had mixed results ... “Previously, physical intergovernmental meetings were represented by a select few per economy that could afford to travel to these closed-door meetings. Economies with smaller travel budgets and small delegations tend to be at a disadvantage in terms of getting their views adequately represented.” But smaller nations may have another problem: unreliable internet access. ... “In addition, virtual meetings do not lend themselves well to effective ‘corridor chats’, where many private conversations and negotiations take place at the sidelines of the meeting. ...” “Remote participants in a virtual meeting generally come with pre-baked positions that sometimes become intractable due to the lack of opportunities for proper engagement ... [resulting in] the inability to reach a compromise in an effective and efficient manner.”

New Pine64 phones with upgraded hardware begin shipping in August
by Peter Reutemann 17 Jul '20

'Yesterday, Pine64 announced the end of the PinePhone UBPorts Community Edition campaign—but more importantly, the company declared the beginning of the postmarketOS Community Edition campaign.

Before anyone gets too excited, we need to make something clear—these devices, while attractively priced, should be considered beta gadgets for tinkerers to experiment and play with. They are not yet fully functional phones, and in their current development status, they are unlikely to be anyone's full-time daily-usage smartphone. The apps don't all work yet—including making calls—and battery life still leaves a lot to be desired.' -- source: https://arstechnica.com/gadgets/2020/07/pine64-launches-postmarketos-editio… 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/

NSA On Securing VPNs
by Lawrence D'Oliveiro 16 Jul '20

16 Jul '20

Bruce Schneier reports <https://www.schneier.com/blog/archives/2020/07/nsa_on_securing.html> on an advisory from the US National Security Agency on how to secure your VPN setup. The document is available in a 10-page or 2-page version. The tips can be summarized as * Reduce the VPN gateway attack surface * Verify on CNSSP-15-compliant algorithms are in use * Avoid using default settings * Remove unused or non-compliant cryptography suites * Apply vendor-provided updates The one about not using default settings I found interesting, the explanation given being that “many vendors provide default configurations, automated configuration scripts, or graphical user interface wizards to aid in the deployment of VPNs”, but that these tools/defaults may prioritize ease of setup over security, and therefore enable extra options that should not be enabled. The longer version gives detailed configuration examples.

Microsoft urges patching severe-impact, wormable server vulnerability
by Peter Reutemann 16 Jul '20

16 Jul '20

'Microsoft is urgently advising Windows server customers to patch a vulnerability that allows attackers to take control of entire networks with no user interaction and, from there, rapidly spread from computer to computer. The vulnerability, dubbed SigRed by the researchers who discovered it, resides in Windows DNS, a component that automatically responds to requests to translate a domain into the IP address computers need to locate it on the Internet. By sending maliciously formed queries, attackers can execute code that gains domain administrator rights and, from there, take control of an entire network. The vulnerability, which doesn’t apply to client versions of Windows, is present in server versions from 2003 to 2019. SigRed is formally tracked as CVE-2020-1350. Microsoft issued a fix as part of this month's Update Tuesday.' -- source: https://arstechnica.com/information-technology/2020/07/microsoft-urges-patc… 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/

But if it does that, it just makes alternatives like RISC-V look more competitive.

Rust Code In The Linux Kernel?
by Lawrence D'Oliveiro 14 Jul '20

14 Jul '20

Looks like several kernel developers, up to and including Linus Torvalds himself, are receptive <https://www.theregister.com/2020/07/13/rust_code_in_linux_kernel/> towards including code written in Mozilla’s Rust language in the Linux kernel. Albeit Torvalds sees it being used, initially at least, in parts “not very central to the kernel itself”, like drivers. A principal feature of Rust is the strict way it manages memory pointers, to limit the scope for common mistakes like memory leaks and double-frees. But unlike other languages like Java, Go or Kotlin, it does not bake the overhead of garbage collection into the language itself. This makes it more suitable for high-performance and lower-level tasks than those languages. More info here: <https://www.rust-lang.org/>.

Linus Torvalds Hopes Intel's AVX-512 'Dies A Painful Death'
by Peter Reutemann 13 Jul '20

13 Jul '20

'"Linux creator Linus Torvalds had some choice words today on Advanced Vector Extensions 512 (AVX-512) found on select Intel processors," reports Phoronix: In a mailing list discussion stemming from the Phoronix article this week on the compiler instructions Intel is enabling for Alder Lake (and Sapphire Rapids), Linus Torvalds chimed in. The Alder Lake instructions being flipped on in GCC right now make no mention of AVX-512 but only AVX2 and others, likely due to Intel pursuing the subset supported by both the small and large cores in this new hybrid design being pursued. The lack of seeing AVX512 for Alder Lake led Torvalds to comment: I hope AVX512 dies a painful death, and that Intel starts fixing real problems instead of trying to create magic instructions to then create benchmarks that they can look good on. I hope Intel gets back to basics: gets their process working again, and concentrate more on regular code that isn't HPC or some other pointless special case. I've said this before, and I'll say it again: in the heyday of x86, when Intel was laughing all the way to the bank and killing all their competition, absolutely everybody else did better than Intel on FP loads. Intel's FP performance sucked (relatively speaking), and it matter not one iota. Because absolutely nobody cares outside of benchmarks. The same is largely true of AVX512 now - and in the future... After several more paragraphs, Torvalds reaches his conclusion. "Stop with the special-case garbage, and make all the core common stuff that everybody cares about run as well as you humanly can." Phoronix notes that Torvalds' comments came "just weeks after he switched to AMD Ryzen Threadripper for his primary development rig."' -- source: https://linux.slashdot.org/story/20/07/12/1729255 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/

From a report: The new image format is considered one of the lightest and most optimized image compression formats, and has already gained praise from companies such as Netflix, which considers it superior to existing image formats such as JPEG, PNG, and even the newer WebP. The acronym of AVIF stands for AV1 Image File Format. As its name hints, AVIF is based on AV1, which is a video codec that was developed in 2015, following a collaboration between Google, Cisco, and Xiph.org (who also worked with Mozilla). At the time, the three decided to pool their respective in-house video codecs (VPX, Thor, and Daala) to create a new one (AV1) that they planned to offer as an open-source and royalty-free alternative to all the commercial video codecs that had fragmented and clogged the video streaming market in the late 2000s and early 2010s.' -- source: https://news.slashdot.org/story/20/07/09/202235 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 Creates “Open Usage Commons”
by Lawrence D'Oliveiro 09 Jul '20

09 Jul '20

From <https://www.theregister.com/2020/07/08/google_trademarks_open_usage_commons/>, Google is creating an organization specifically to deal with trademark issues, entirely separate from code. FSF Europe’s Alexander Sander says: “Trademarks issues are becoming more and more relevant for Free Software. This development is mainly due to the fact that Free Software is increasingly and successfully used in the commercial sector.” True, that. Consider the stoush between Debian and Mozilla over the “Firefox” trademark and branding, and the consequent creation of the “Iceweasel” fork. (Looks like that was eventually resolved amicably.) However, note this counterpoint from the Linux Foundation: "Under US trademark law you are not able to effectively separate ownership of a project mark from control of the underlying open source project."

Over 100 Wi-Fi Routers Fail Major Security Test -- Protect Yourself Now
by Peter Reutemann 09 Jul '20

09 Jul '20

'Tom's Guide: Using its own analytical software, the [Fraunhofer Institute] tested the most recently available firmware for 117 home Wi-Fi models currently sold in Europe, including routers from ASUS, D-Link, Linksys, Netgear, TP-Link, Zyxel and the small German brand AVM. The models themselves were not physically tested. A full list of the tested models and firmware is on GitHub. The institute was not able to examine the firmware of 10 more models, mostly from Linksys. The report notes (PDF) that many firmware updates are issued without fixing known flaws. So what can you do? You can make sure that the next router you buy automatically installs firmware updates. You can check to see whether your current router does so, or makes it fairly easy to install firmware updates manually. You should also make sure that the administrative password for your router has been changed from the factory default password. (Check the list of default passwords at https://www.routerpasswords.com.) You should also check its administrative interface to make sure that UPnP and remote access are disabled. And if your router was first released more than 5 years ago, consider buying a newer model unless it meets all of the above criteria. Alternatively, you could try to "flash" your older router to run more secure open-source router firmware such as OpenWrt, DD-WRT or Tomato. "The worst case regarding high severity CVEs [widely known flaws] is the Linksys WRT54GL powered by the oldest kernel found in our study," the report said, noting that this model uses the 2.4.20 kernel from 2002. "There are 579 high severity CVEs affecting this product." "That particular model last had its firmware updated in January 2016, one of the oldest firmwares in the study," adds Tom's Guide. "The Linksys WRT54GL was first released in 2005 and is still sold today, even though it handles Wi-Fi protocols only up to 802.11g. However, the WRT54G series is possibly the best-selling family of Wi-Fi routers ever..."' -- source: https://mobile.slashdot.org/story/20/07/08/2058240 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 Canonical Bring Flutter Apps To Linux and the Snap Store
by Peter Reutemann 09 Jul '20

09 Jul '20

'Google is partnering with the Ubuntu Desktop team at Canonical to bring Linux support to its open source UI framework Flutter. Today's Linux alpha announcement also means Flutter developers can now deploy their apps to the Snap Store. Flutter group product manager Tim Sneath argues this is a big milestone because UI frameworks rarely become versatile and powerful enough for an operating system to depend on. He pointed to Windows being written in C++ rather than .NET, even for applets like the Calculator. Sneath also believes this shows Canonical is willing to invest in a first-class way to build apps for Linux, making Flutter on Linux an official part of Ubuntu. Additionally, enterprises can feel confident about picking Flutter -- it's more evidence of its longevity and technical excellence, Sneath said.' -- source: https://linux.slashdot.org/story/20/07/08/1722203 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 Company SUSE Outbids Competitors for Fast-growing Startup Rancher Labs
by Peter Reutemann 09 Jul '20

09 Jul '20

'SUSE, a Linux distribution company controlled by private equity firm EQT, has agreed to acquire Rancher Labs, a start-up with technology that helps organizations run software in virtual containers across many servers. From a report: The companies announced the deal Wednesday but didn't disclose the terms. Two people familiar with the deal said SUSE is paying $600 million to $700 million. The transaction suggests that even during a recession, demand remains high for technology that can enable companies to operate more efficiently. Talks between the companies began in the spring, and the process became competitive with additional bids, Ursheet Parikh, a partner at Rancher backer Mayfield Fund, told CNBC on Tuesday. There were "lots of Zoom calls," Parikh said. In the past few years, with the rise of start-ups such as Docker, containers became a trendy alternative to more traditional virtualization technology for running applications on each computer server in a company data center. Amazon, Microsoft and other cloud providers came out with services that developers can use to place code in containers, and in 2017 SUSE introduced its own service for managing containers. The companies haven't finalized integration plans as the deal still faces regulatory approval.' -- source: https://linux.slashdot.org/story/20/07/08/147202 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 Suspends Firefox Send Service While It Addresses Malware Abuse
by Peter Reutemann 09 Jul '20

09 Jul '20

'Mozilla has temporarily suspended the Firefox Send file-sharing service as the organization investigates reports of abuse from malware operators and while it adds a "Report abuse" button. The browser maker took down the service today after ZDNet reached out to inquire about Firefox Send's increasing prevalence in current malware operations. Since last year, several malware operations have hosted payloads on the service. This includes ransomware gangs like REvil/Sodinokibi, financial crime crews like FIN7, the Zloader and Ursnif banking trojans operations, and government surveillance groups targeting human rights defenders. Reasons include the fact that Firefox Send doesn't have an Report Abuse mechanism, all file uploads are encrypted (useful to dodge malware scanners), and the Firefox URL is whitelisted in most orgs (useful for bypassing email filters).' -- source: https://news.slashdot.org/story/20/07/08/1811228 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 H.266 VCC Codec Up To 50% More Efficient Than Previous Standard
by Peter Reutemann 07 Jul '20

07 Jul '20

'The Fraunhofer Heinrich Hertz Institute on Tuesday announced the H.266 Versatile Video Coding codec, which will power more data-efficient video capture and transmission on future iPhones. AppleInsider reports: Apple adopted the predecessor to the new codec, H.265/HEVC, in iOS 11. The updated video codec, which was developed after years of research and standardization, will bring a number of tangible benefits to future iPhone users. In its announcement, the Fraunhofer HHI said that H.266 will reduce data requirements by around 50% thanks to improved compression. With the previous HEVC codec, it took about 10GB of data to transmit a 90-minute ultra-high definition (UHD) video. H.266 can do that with 5GB. The codec, as detailed in a 500-page specification, was designed from the ground up for use with 4K and 8K streaming. It'll allow users to store more high-definition video and reduce the amount of data on cellular networks.' -- source: https://apple.slashdot.org/story/20/07/06/219225 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 Likes His New AMD Threadripper System
by Peter Reutemann 06 Jul '20

06 Jul '20

'This week Linus Torvalds and Dirk Hohndel re-created their keynote conversation for a special all-virtual edition of the Open Source Summit and Embedded Linux Conference North America. ZDNet reports: While COVID-19 has slowed down many technologies, while speeding up other tech developments, it hasn't affected Linux development much at all. "None of my co-developers have been hugely impacted either. I was worried for a while because one of our developers was offline for a month or two.... [But,] it turned out that it was just RSI [repetitive strain injury], and RSI is kind of an occupational hazard to deal with." He added. "One of the things that is so interesting about the Linux community is how much it has always been email-based and remote, how rarely we get together in person...." Torvalds trusts this new build. Indeed, he ran his end of the videoconference from his new developer machine running the first release candidate of 5.8. Thinking of his new AMD Threadripper 3970x-based processor-powered developer desktop, Torvalds later added that, although he had been concerned about its fan noise it actually works well for him. Torvalds moved to this new homebrew computer because he needed the speed. "My 'allmodconfig' test builds are now three times faster than they used to be." That's important because Torvalds "strives to do about 20 to 30 [pull requests] a day, which is above my limit, ... [but] in order to do that, [he needs] a lot of computing power.

Ads Are Taking Over Samsung's Galaxy Smartphones
by Peter Reutemann 02 Jul '20

02 Jul '20

'Max Weinbach, writing for Android Police: I have been using Samsung phones every day for almost 4 years. It was because Samsung had fantastic hardware paired with --depending on the year -- good software. 2020 is the first year in a while I'm not using a Samsung phone as my daily driver. The reason? Ads. Ads in Samsung phones never really bothered me, at least not until the past few months. It started with the Galaxy Z Flip. A tweet from Todd Haselton of CNBC is what really caught my eye. Samsung had put an ad from DirectTV in the stock dialer app. This is really something I never would have expected from any smartphone company, let alone Samsung. It showed up in the "Places" tab in the dialer app, which is in partnership with Yelp and lets you search for different businesses directly from the dialer app so you don't need to Google somewhere to find the address or phone number. I looked into it, to see if this was maybe a mistake on Yelp's part, accidentally displaying an ad where it shouldn't have, but nope. The ad was placed by Samsung, in an area where it could blend in so they could make money. Similar ads exist throughout a bunch of Samsung apps. Samsung Music has ads that look like another track in your library. Samsung Health and Samsung Pay have banners for promotional ads. The stock weather app has ads that look like they could be news. There is also more often very blatant advertising in most of these apps as well. Samsung Music will give you a popup ad for Sirius XM, even though Spotify is built into the Samsung Music app. You can hide the SiriusXM popup, but only for 7 days at a time. A week later, it will be right back there waiting for you. Samsung will also give you push notification ads for new products from Bixby, Samsung Pay, and Samsung Push Service.

Google Removes 25 Android Apps Caught Stealing Facebook Credentials
by Peter Reutemann 01 Jul '20

01 Jul '20

'Google has removed this month 25 Android apps from the Google Play Store that were caught stealing Facebook credentials. From a report: Before being taken down, the 25 apps were collectively downloaded more than 2.34 million times. The malicious apps were developed by the same threat group and despite offering different features, under the hood, all the apps worked the same. According to a report from French cyber-security firm Evina shared with ZDNet today, the apps posed as step counters, image editors, video editors, wallpaper apps, flashlight applications, file managers, and mobile games. The apps offered a legitimate functionality, but they also contained malicious code. Evina researchers say the apps contained code that detected what app a user recently opened and had in the phone's foreground. If the app was Facebook, the malicious app would overlay a web browser window on top of the official Facebook app and load a fake Facebook login page (see image below: blue bar = actual Facebook app, black bar = phishing page).' -- source: https://tech.slashdot.org/story/20/06/30/1411202 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/

Android's AirDrop Competitor Is Coming Soon
by Peter Reutemann 01 Jul '20

01 Jul '20

'Android's long-awaited "Nearby Sharing" feature, which allows you to share files between Android devices wirelessly, is rolling out to beta testers. Android Police reports: Nearby Sharing may appear slightly differently depending on the type of content you try to share. In all cases, it shows up as an app in the apps list on the share sheet, but you may also get a smaller prompt just under the content preview, more like it did in the previous Android 11 video leak. We tested it on a Pixel 4 XL and Pixel 3a running Android 10, but the appearance may also vary on other versions of Android. Note that Nearby Share works for both files like photos or videos, as well as other shareable content like Tweets and URLs. It probably works with a lot of things. Select Nearby Share in the share sheet as the target, and you're prompted to turn on the feature, if it's the first time you've used it. The quick setup process lets you configure your default device name and device visibility settings, though those can also be changed later. Once you have it enabled, Nearby Sharing starts looking for other nearby devices. The interface is pretty simple: A big X in the top left corner backs you out, your avatar on the right takes you to a settings pane that lets you configure things like your device name, visibility, and which mechanism to use to make the transfer (i.e., whether to use your internet connection for small files, to stick to Wi-Fi, or to always share offline). Google says Nearby Share is currently in limited testing via the Play Services beta: "We're currently conducting a beta test of a new Nearby Share feature that we plan to share more information on in the future. Our goal is to launch the feature with support for Android 6+ devices as well as other platforms."' -- source: https://mobile.slashdot.org/story/20/06/30/2014259 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 Declined To Implement 16 Web APIs in Safari Due To Privacy Concerns
by Peter Reutemann 30 Jun '20

30 Jun '20

'Apple said last week that it declined to implement 16 new web technologies (Web APIs) in Safari because they posed a threat to user privacy by opening new avenues for user fingerprinting. Technologies that Apple declined to include in Safari because of user fingerprinting concerns include: Web Bluetooth - Allows websites to connect to nearby Bluetooth LE devices. Web MIDI API - Allows websites to enumerate, manipulate and access MIDI devices. Magnetometer API - Allows websites to access data about the local magnetic field around a user, as detected by the device's primary magnetometer sensor. Web NFC API - Allows websites to communicate with NFC tags through a device's NFC reader. Device Memory API - Allows websites to receive the approximate amount of device memory in gigabytes. Network Information API - Provides information about the connection a device is using to communicate with the network and provides a means for scripts to be notified if the connection type changes. Battery Status API - Allows websites to receive information about the battery status of the hosting device. Web Bluetooth Scanning - Allows websites to scan for nearby Bluetooth LE devices. Ambient Light Sensor - Lets websites get the current light level or illuminance of the ambient light around the hosting device via the device's native sensors. [...] The vast majority of these APIs are only implemented in Chromium-based browsers, and very few on Mozilla's platform. Apple claims that the 16 Web APIs above would allow online advertisers and data analytics firms to create scripts that fingerprint users and their devices.

A decidedly non-Linux distro walkthrough: Haiku R1/beta2
by Peter Reutemann 30 Jun '20

'Earlier this month, the Haiku project released the second beta of its namesake operating system, Haiku. Haiku is the reimagining of a particularly ambitious, forward-looking operating system from 1995—Be, Inc.'s BeOS. BeOS was developed to take advantage of Symmetrical Multi-Processing (SMP) hardware using techniques we take for granted today—kernel-scheduled pre-emptive multitasking, ubiquitous multithreading, and BFS—a 64-bit journaling filesystem of its very own. [...] In June 2020—nineteen years after OpenBeOS was born, and sixteen after its rename to Haiku—the project released its second beta distribution. The project still adheres to backward application compatibility with 1990s BeOS—although only in its 32-bit version, which I did not test.' -- source: https://arstechnica.com/gadgets/2020/06/a-decidedly-non-linux-distro-walkth… 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 option will allow users to enable/disable experimental features under Preferences... [In Firefox 79] Navigate to Preferences by entering about:preferences in the browser's address bar or click the gear icon and got to "Preferences." Discover and set browser.preferences.experimental to True.

Journalist's Phone Hacked: All He Had To Do Was Visit a Website. Any Website.
by Peter Reutemann 28 Jun '20

28 Jun '20

'The iPhone that Moroccan journalist Omar Radi used to contact his sources also allowed his government to spy on him (and at least two other journalists), reports the Toronto Star, citing new research from Amnesty International. Slashdot reader Iwastheone shares their report: Their government could read every email, text and website visited; listen to every phone call and watch every video conference; download calendar entries, monitor GPS coordinates, and even turn on the camera and microphone to see and hear where the phone was at any moment. Yet Radi was trained in encryption and cyber security. He hadn't clicked on any suspicious links and didn't have any missed calls on WhatsApp — both well-documented ways a cell phone can be hacked. Instead, a report published Monday by Amnesty International shows Radi was targeted by a new and frighteningly stealthy technique. All he had to do was visit one website. Any website. Forensic evidence gathered by Amnesty International on Radi's phone shows that it was infected by "network injection," a fully automated method where an attacker intercepts a cellular signal when it makes a request to visit a website. In milliseconds, the web browser is diverted to a malicious site and spyware code is downloaded that allows remote access to everything on the phone. The browser then redirects to the intended website and the user is none the wiser. Two more human rights advocates in Morocco have been targeted by the same malware, the article reports.' -- source: https://yro.slashdot.org/story/20/06/27/029222 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/

Comcast Becomes the First ISP To Join Mozilla's TRR Program
by Peter Reutemann 26 Jun '20

26 Jun '20

'Comcast has joined Cloudflare and NextDNS in partnering with Mozilla's Trusted Recursive Resolver program, which aims to make DNS more trusted and secure. Neowin reports: Commenting on the move, Firefox CTO Eric Rescorla, said: "Comcast has moved quickly to adopt DNS encryption technology and we're excited to have them join the TRR program. Bringing ISPs into the TRR program helps us protect user privacy online without disrupting existing user experiences. We hope this sets a precedent for further cooperation between browsers and ISPs." With its TRR program, Mozilla said that encrypting DNS data with DoH is just the first step in securing DNS. It said that the second step requires companies handling the data to have appropriate rules in place for handling it. Mozilla believes these rules include limiting data collection and retention, ensuring transparency about any retained data, and limiting the use of the resolver to block access or modify content. Ars Technica notes that joining Mozilla's program means that Comcast agreed that it won't "retain, sell, or transfer to any third party (except as may be required by law) any personal information, IP addresses, or other user identifiers, or user query patterns from the DNS queries sent from the Firefox browser," along with other requirements. When the change happens, it'll be automatic for users unless they've chosen a different DoH provider or disabled DoH altogether. Comcast told Ars yesterday that "Firefox users on Xfinity should automatically default to Xfinity resolvers under Mozilla's Trusted Recursive Resolver program, unless they have manually chosen a different resolver, or if DoH is disabled. The precise mechanism is still being tested and the companies plan to document it soon in an IETF [Internet Engineering Task Force] Draft."' -- source: https://tech.slashdot.org/story/20/06/25/1953252 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/

Safari 14 Removes Flash, Gets Support for Breach Alerts, HTTP/3, and WebP
by Peter Reutemann 25 Jun '20

25 Jun '20

'Safari 14, scheduled to be released later this fall with iOS 14 and macOS 11, is a release that is packed choke-full with features. From a report: The biggest and most important of the new additions is support for WebExtensions, a technology for creating browser extensions. What this means for Safari users is that starting this fall, they'll see a huge influx of new Safari extensions as add-on developers are expected to port their existing Chrome and Firefox extensions to work on Apple's browser as well. Apple said that, for now, WebExtensions will only be available for Safari on macOS. Safari 14 is also an end of an era, as this will be the first version of Safari that won't support Adobe Flash Player content. But while old stuff is being removed, new stuff is also being added. One of the new technologies added to Safari is support for HTTP/3, a new web standard that will make loading websites faster and safer. Another important addition in Safari is support for WebP, a lightweight image format that has been gaining widespread adoption across the internet. The format, created by Google, serves as an alternative to the older JPEG format, and Safari has been the last browser to add support for it. [...] But Safari hasn't been lagging behind other browsers just in terms of HTTP/3 and WebP support. Apple has also added support for another cool feature, namely breach alerts, already present in both Chrome and Firefox. Starting this fall, Apple says that Safari 14 will scan a user's locally-stored passwords and show a prompt if one or more of the user's credentials are present in publicly available lists of breached accounts.' -- source: https://yro.slashdot.org/story/20/06/24/1753236 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 Says It Will Keep Less Browser History and Location Data By Default

Activity from the web and from apps would also default to 18 months for new accounts, he said. "This means your activity data will be automatically and continuously deleted after 18 months, rather than kept until you choose to delete it," Pichai said. There will be no automatic change for existing accounts and people who already have location history turned on in their Google settings, but the company plans to inform existing users of the option to set up auto-delete after three to 18 months, he said. People also have the option to turn the setting off.' -- source: https://tech.slashdot.org/story/20/06/24/2030254 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 Edge Accused of Sneakily Importing Firefox Data In Windows 10
by Peter Reutemann 24 Jun '20

24 Jun '20

'Some Firefox users have discovered that the new default Windows 10 browser, which is shipped to their devices via Windows Update, sometimes imports the data from Mozilla's application even if they don't give their permission.

Several users confirmed on reddit that this behavior happened on their computers too. Microsoft has remained tight-lipped on this, so for the time being, it's still not known why Edge imports Firefox data despite the initial wizard actually killed off manually by the user.

80,000 Printers Are Exposing Their IPP Port Online
by Peter Reutemann 24 Jun '20

24 Jun '20

'In a report published earlier this month, security researchers from the Shadowserver Foundation, a non-profit organization focused on improving cyber-security practices across the world, have published a warning about companies that are leaving printers exposed online. More specifically, Shadowserver experts scanned all the four billion routable IPv4 addresses for printers that are exposing their IPP port. IPP stands for "Internet Printing Protocol" and, as the name suggests, is a protocol that allows users to manage internet-connected printers and send printing jobs to printers hosted online. The difference between IPP and the multiple other printer management protocols is that IPP is a secure protocol that supports advanced features such as access control lists, authentication, and encrypted communications. However, this doesn't mean that device owners are making use of any of these features. Shadowserver experts said they specifically scanned the internet for IPP-capable printers that were left exposed without being protected by a firewall and allowed attackers to query for local details via the "Get-Printer-Attributes" function. In total, experts said they usually found an average of around 80,000 printers exposing themselves online via the IPP port on a daily basis. The number is about an eighth of all IPP-capable printers currently connected online. A normal scan with the BinaryEdge search engine reveals a daily count of between 650,000 and 700,000 devices with their IPP port (TCP/631) reachable via the internet. What are the issues with not securing the IPP port? Shadowserver experts say this port can be used for intelligence gathering, since many of the printers scanned returned additional info about themselves, such as printer names, locations, models, firmware, organization names, and even Wi-Fi network names. "To configure IPP access control and IPP authentication features, users are advised to check their printers' manuals," adds ZDNet. "Most printers have an IPP configuration section in their administration panel from where users can enable authentication, encryption, and limit access to the device via access lists."' -- source: https://hardware.slashdot.org/story/20/06/23/2049236 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/

ARM-Based Japanese Supercomputer is Now the Fastest in the World
by Peter Reutemann 24 Jun '20

24 Jun '20

'A Japanese supercomputer has taken the top spot in the biannual Top500 supercomputer speed ranking. Fugaku, a computer in Kobe co-developed by Riken and Fujitsu, makes use of Fujitsu's 48-core A64FX system-on-chip. It's the first time a computer based on ARM processors has topped the list. From a report: Fugaku turned in a Top500 HPL result of 415.5 petaflops, 2.8 times as fast as IBM's Summit, the nearest competitor. Fugaku also attained top spots in other rankings that test computers on different workloads, including Graph 500, HPL-AI, and HPCG. No previous supercomputer has ever led all four rankings at once. While fastest supercomputer rankings normally bounce between American- and Chinese-made systems, this is Japan's first system to rank first on the Top500 in nine years since Fugaku's predecessor, Riken's K computer. Overall there are 226 Chinese supercomputers on the list, 114 from America, and 30 from Japan. US-based systems contribute the most aggregate performance with 644 petaflops' -- source: https://tech.slashdot.org/story/20/06/23/1614232 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 10 Linux Subsystem: You Get GPU Acceleration -- With Intel, AMD, Nvidia Drivers
by Peter Reutemann 23 Jun '20

23 Jun '20

'Nvidia, Intel and AMD have announced their support for Microsoft's new effort to bring graphics processor support to the Windows 10 Windows Subsystem for Linux to enhance machine-learning training. From a report: GPU support for WSL arrived on Wednesday in the Dev Channel preview of Windows 10 build 20150 under Microsoft's reorganized testing structure, which lets it test Windows 10 builds that aren't tied to a specific future feature release. Microsoft announced upcoming GPU support for WSL a few weeks ago at Build 2020, along with support for running Linux GUI apps. The move on GPU access for WSL is intended to bring the performance of applications running in WSL2 up to par with those running on Windows. GPU compute support is the feature most requested by WSL users, according to Microsoft. The 20150 update includes support for Nvidia's CUDA parallel computing platform and GPUs, as well as GPUs from AMD and Intel. It also supports DirectML (Direct Machine Learning), Microsoft's Windows 10 API for hardware-accelerated machine learning.

'In an effort to curb the spread of misinformation on its platform, Google said Monday it would begin to fact-check Google Images search results. From a report: The danger of text-based misinformation could be dwarfed by that posed by misleading, manipulated and outright fake photos and videos, including convincing "deepfakes" generated with the aid of artificial intelligence. The move, a first among major search engines, comes as tech firms continue to wrestle with how to address the misinformation that continue to run rampant on their platforms. Beginning Monday, Google will surface fact-check information in Google Images around the world, a similar effort to what is does in its regular search and news results.' -- source: https://tech.slashdot.org/story/20/06/22/1634217 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/

Nvidia Engineer Releases Open-Sourced Vulkan Graphics Driver for the Raspberry Pi
by Peter Reutemann 22 Jun '20

22 Jun '20

'Earlier this year, the Raspberry Pi Foundation hooked up with Igalia to start development on an open-sourced Vulkan graphics driver for the Raspberry Pi. However, Martin Thomas, an engineer at Nvidia, beat them to the punch. Thomas announced yesterday via his personal Twitter that his RPi-VK-Driver is ready for primetime. The talented engineer had been working on the Vulkan driver in his spare time for more than two years. Technically, Thomas' iteration isn't a Vulkan driver per se because it doesn't comply with the official standards established by The Khronos Group. Nonetheless, the resourceful developer produced a driver that adheres to the Vulkan parameters as much as possible, and as close as the hardware would permit it. There's just one limitation with the RPi-VK-Driver though. Unlike the official Vulkan driver that's still in the works, Thomas' version is only compatible with the Broadcom VideoCore IV GPU that's found inside the Raspberry Pi 1, 2, 3 and Zero devices.' -- source: https://tech.slashdot.org/story/20/06/21/185227 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/

Anyone Can Build This Open Source, DRM-Free Kindle Alternative
by Peter Reutemann 21 Jun '20

21 Jun '20

'It’s harder to get an open source e-reader than you might think. Kindles are popular, but they lock you into Amazon’s ecosystem. Amazon’s books come with digital rights protection and the company can remove them from your device whenever it wants. Those problems exist on tablets from Barnes and Nobles, Google, and Apple, too. When it comes to open source reading, there’s just no good options. The Open Book Project wants to change that. As first spotted by Hackster.io, “the Open Book aims to be a simple device that anyone with a soldering iron can build for themselves,” designer Joey Castillo said on the GitHub repository for the project. Castillo is still prototyping the device, and his goal is to build an e-reader that anyone can redesign, recode, or accessorize as they see fit. Of course, it should be able to read books in any format, from ePub to MOBI and everything in between. Castillo’s prototype is built from a circuit board of his own design. The design works in the Adafruit Feather ecosystem, a user friendly set of development boards and electronics. Castillo has listed all the parts you’ll need to build your own open source e-reader and tweak the design on his GitHub. (Castillo is still working on the device’s firmware, so you’ll have to write it yourself or wait for a release.)' -- source: https://www.vice.com/en_us/article/7x5kpb/anyone-can-build-this-open-source… 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/

AI Magic Comes At A Price

Interview with a software developer <https://www.theregister.com/2020/06/19/generative_adversarial_networks_are_…> about the pitfalls of using Generative Adversarial Networks (GANs) for the specific task of adding colour to old monochrome images. You can get them to produce good results most of the time, then every now and then they will go wrong in some weird and unsettling way: "GANs would spit out very weird specific glitches like odd splashes of colour on someone's hand and it made them look creepy," he told us. In some examples, people have turned an eerie alien green. And trying to tweak things manually can just as easily make things worse as better.

Lawsuit vs. Western Digital wants to end any use of SMR in NAS drives
by Peter Reutemann 19 Jun '20

19 Jun '20

'Law firm Hattis & Lukacs has filed an amendment to its class-action lawsuit against Western Digital for including SMR technology in its WD Red line of NAS drives. The amendment adds five more named plaintiffs from five new states, and it includes significant additional technical detail. If you aren't up to date on the SMR saga, this is one article in an ongoing series. The short version: SMR—Shingled Magnetic Recording—is a relatively new hard drive recording technology that allows higher data densities. It does so by laying down overlapping tracks—like shingles on a roof—with a write head that's wider than the read head. Unfortunately, this technology makes rewriting existing disk sectors agonizingly slow in many cases—rewriting a single 4KiB sector will generally mean needing to both read and rewrite an entire 256MiB zone. The original American class-action suit (there's a Canadian one as well) had a single named plaintiff, Wisconsin's Nicholas Malone. The amendment features five new plaintiffs, each from a different state, and tells each plaintiff's story in detail. New York plaintiff Steve Gravel's story is particularly wince-inducing—he wasn't just using the drives for photo and movie storage; he had an iSCSI target on his QNAP NAS, and the performance decrease when he replaced CMR drives with SMR was, as you might expect, terrible.' -- source: https://arstechnica.com/information-technology/2020/06/lawsuit-vs-western-d… 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 pushes “text fragment links” with new Chrome extension
by Peter Reutemann 19 Jun '20

19 Jun '20

'Google has been cooking up an extension to the URL standard called "Text Fragments." The new link style will allow you to link not just to a page but to specific text on a page, which will get scrolled to and highlighted automatically once the page loads. It's like an anchor link, but with highlighting and creatable by anyone. The feature has actually been supported in Chrome since version 80, which hit the stable channel in February. Now a new extension from Google makes it easy to create this new link type, which will work for anyone else using Chrome on desktop OSes and Android. Google has proposed the idea to the W3C and hopes other browsers will adopt it, but even if they don't, the links are backward-compatible.' -- source: https://arstechnica.com/gadgets/2020/06/google-pushes-text-fragment-links-w… 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/

Massive Spying on Users of Google's Chrome Shows New Security Weakness
by Peter Reutemann 19 Jun '20

19 Jun '20

'A newly discovered spyware effort attacked users through 32 million downloads of extensions to Google's market-leading Chrome web browser, researchers at Awake Security told Reuters, highlighting the tech industry's failure to protect browsers as they are used more for email, payroll and other sensitive functions. From a report: Google said it removed more than 70 of the malicious add-ons from its official Chrome Web Store after being alerted by the researchers last month. "When we are alerted of extensions in the Web Store that violate our policies, we take action and use those incidents as training material to improve our automated and manual analyses," Google spokesman Scott Westover told Reuters. Most of the free extensions purported to warn users about questionable websites or convert files from one format to another. Instead, they siphoned off browsing history and data that provided credentials for access to internal business tools. Based on the number of downloads, it was the most far-reaching malicious Chrome store campaign to date, according to Awake co-founder and chief scientist Gary Golomb.' -- source: https://yro.slashdot.org/story/20/06/18/1341219 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/

A Medical Device Maker Threatens iFixit Over Ventilator Repair Project
by Peter Reutemann 18 Jun '20

18 Jun '20

'STERIS Corporation, a company that makes sterilization and other medical equipment, sent a letter to iFixit claiming their online database of repair manuals for ventilators and medical equipment violates their copyrights. Motherboard reports: "It has come to my attention that you have been reproducing certain installation and maintenance manuals relating to our products, documentation which is protected by copyright law," the letter said. The letter then went on to tell [Kyle Wiens, CEO of iFixit] to remove all Steris copyrighted material from the iFixit website within 10 days of the letter. As Motherboard reported in March, major manufacturers of medical devices have long made it difficult for their devices to be repaired through third party repair professionals. Manufacturers have often lobbied against right to repair legislation and many medical devices are controlled by artificial "software locks" that allow only those with authorization to make modifications. "I'm disappointed that Steris is resorting to legal threats to stop hospitals from having access to information about how to maintain critical sterilization equipment during a pandemic," Wiens told Motherboard in an email. "No manufacturer should be stopping hospitals from repairing their equipment," Wiens said. "The best way to ensure patient safety is to make sure that equipment is being maintained regularly using the manufacturer's recommended procedures. The only way to do that is if hospitals have up to date manuals." With regards to the letter sent by Steris, Wiens said iFixit has not removed any material from its website. "We explained to Steris that what we did is a lawful and protected fair use under the U.S. Copyright act," Wiens said. "iFixit is protected by Section 512 of the Digital Millennium Copyright Act, which allows online platforms to host content contributed by users provided they comply with the Act's requirements, which iFixit does," a letter to Steris from the Electronic Frontier Foundation on behalf of iFixit said.' -- source: https://science.slashdot.org/story/20/06/17/2013232 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 Will Soon Bake Anti-malware Defenses Directly Into its CPUs
by Peter Reutemann 16 Jun '20

16 Jun '20

'The history of hacking has largely been a back-and-forth game, with attackers devising a technique to breach a system, defenders constructing a countermeasure that prevents the technique, and hackers devising a new way to bypass system security. On Monday, Intel is announcing its plans to bake a new parry directly into its CPUs that's designed to thwart software exploits that execute malicious code on vulnerable computers. From a report: Control-Flow Enforcement Technology, or CET, represents a fundamental change in the way processors execute instructions from applications such as Web browsers, email clients, or PDF readers. Jointly developed by Intel and Microsoft, CET is designed to thwart a technique known as return-oriented programming, which hackers use to bypass anti-exploit measures software developers introduced about a decade ago. While Intel first published its implementation of CET in 2016, the company on Monday is saying that its Tiger Lake CPU microarchitecture will be the first to include it. ROP, as return-oriented programming is usually called, was software exploiters' response to protections such as Executable Space Protection and address space layout randomization, which made their way into Windows, macOS, and Linux a little less than two decades ago. These defenses were designed to significantly lessen the damage software exploits could inflict by introducing changes to system memory that prevented the execution of malicious code. Even when successfully targeting a buffer overflow or other vulnerability, the exploit resulted only in a system or application crash, rather than a fatal system compromise.' -- source: https://it.slashdot.org/story/20/06/15/1453215 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/
