Facebook Fiercely Guards The Privacy Of Its Advertisers
by Lawrence D'Oliveiro 07 Aug '21

07 Aug '21

Facebook has shut down all accounts and access for New York University’s Ad Observatory project <https://www.theregister.com/2021/08/04/facebook_research_lockdown/>. This project was using a browser extension to garner information about ads shown to Facebook users without the cooperation of Facebook itself. However, the project <https://adobservatory.org/> tries to be fully transparent about what it is doing to volunteers who choose to install the extension, and as is common these days, the source code is available on GitHub. Part of Facebook’s excuse is that the extension is somehow scraping information from the website that is “not publicly viewable”. How such information is getting to the user’s browser is not explained. Facebook has its own alternative research platform, called “FORT”, that it makes available to selected researchers on a strictly controlled basis. One of the conditions is that Facebook is given pre-publication access to research papers in order to identify--and remove--information that it considers to be “confidential”. Naturally, this kind of thing rings alarm bells for researchers. Another group has published an open letter <https://freedom-to-tinker.com/2021/08/05/facebooks-illusory-promise-of-tran…> pointing out why this is not an acceptable alternative.

Firefox Lost Almost 50 Million Users In 3 Years
by Peter Reutemann 05 Aug '21

05 Aug '21

'A report from It's FOSS, written by Ankush Das: Mozilla's Firefox is the only popular alternative to Chromium-based browsers. It has been the default choice for Linux users and privacy-conscious users across every platform. However, even with all benefits as one of the best web browsers around, it is losing its grip for the past few years. I came across a Reddit thread by u/nixcraft, which highlighted more details on the decline in the userbase of Firefox since 2018. And surprisingly, the original source for this information is Firefox's Public Data Report. As per the official stats, the reported number of active (monthly) users was about 244 million at the end of 2018. And, it seems to have declined to 198 million at the end of Q2 2021. So, that makes it a whopping ~46 million decline in the userbase. Considering 2021 is the year when privacy-focused tools saw a big boost in their userbase, Mozilla's Firefox is looking at a constant decline. Especially when Firefox manages to introduce some industry-first privacy practices. Quite the irony, eh? Just for fun, here's a timeline of our stories reporting on Firefox's download milestones from the mid-2000s: September 19, 2004: 1 Million Firefoxes in 4 Days December 12, 2004: Firefox Reaches 10 Million Downloads February 17, 2005: Firefox Breaks 25 Million Downloads April 26, 2005: Firefox nears 50 Million Downloads July 29, 2005: Firefox Downloads Reach 75 Million October 19, 2005: Firefox Tops 100 Million Downloads September 11, 2007: Firefox Hits 400 Million Downloads July 3, 2008: Firefox Breaks 8 Million, Gets Into Guinness' -- source: https://news.slashdot.org/story/21/08/04/2137205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Chrome To No Longer Show Secure Website Indicators
by Peter Reutemann 04 Aug '21

04 Aug '21

'Google Chrome will no longer show whether a site you are visiting is secure and only show when you visit an insecure website. Bleeping Computer reports: To further push web developers into only using HTTPS on their sites, Google introduced the protocol as a ranking factor. Those not hosting a secure site got a potentially minor hit in their Google search results rankings. It has appeared to have worked as according to the 'HTTPS encryption on the web' of Google's Transparency Report, over 90% of all browser connections in Google Chrome currently use an HTTPS connection. Currently, when you visit a secure site, Google Chrome will display a little locked icon indicating that your communication with the site is encrypted, as shown below. As most website communication is now secure, Google is testing a new feature that removes the lock icon for secure sites. This feature is available to test in Chrome 93 Beta, and Chrome 94 Canary builds by enabling the 'Omnibox Updated connection security indicators' flag. With this feature enabled, Google Chrome will only display security indicators when the site is not secure. For businesses who wish to have continued HTTPS security indicators, Google has added an enterprise policy for Chrome 93 named 'LockIconInAddressBarEnabled' that can be used to enable the lock icon again on the address bar.

Google Will Kill Off Very Old Versions of Android Next Month
by Peter Reutemann 04 Aug '21

04 Aug '21

'Ars Technica: Google has started emailing users of very old Android devices to tell them it's time to say goodbye. Starting September 27, devices running Android 2.3.7 and lower will no longer be able to log in to Google services, effectively killing a big portion of the on-rails Android experience. As Google puts it in an official community post, "If you sign in to your device after September 27, you may get username or password errors when you try to use Google products and services like Gmail, YouTube, and Maps." Android is one of the most cloud-based operating systems ever. Especially in older versions, many included apps and services were tied to your Google login, and if that stops working, a large chunk of your phone is bricked. While Android can update many core components without shipping a full system update today, Android 2.3.7 Gingerbread, released around 10 years ago, was not so modular. The individual Google apps started to be updatable through the Android Market/Play Store, but signing in to Google was still a system-level service and is frozen in time. Any Google services wanting to allow sign-ins from those versions would have to conform to 2011-era security standards, which means turning off two-factor authentication and enabling a special "allow less-secure access" setting in your Google account. Really, these old Android versions have to die eventually because they're just too insecure. Google shows active user base breakdowns for Android versions in Android Studio, and Gingerbread has such a low device count that it doesn't even make the list. It's less than 0.2 percent of active devices, behind 14 other versions of Android. Users of these old devices could still sideload a third-party app store and find replacements for all the Google apps, but if you're a technical user and can't get a new device, there's a good chance you could load a whole new operating system with an aftermarket Android ROM. After September 27, the oldest version of Android you'll be able to sign in to is Android 3.0 Honeycomb, which is only for tablets.' -- source: https://tech.slashdot.org/story/21/08/03/207222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

AMD and Valve Working On New Linux CPU Performance Scaling Design
by Peter Reutemann 03 Aug '21

03 Aug '21

'Along with other optimizations to benefit the Steam Deck, AMD and Valve have been jointly working on CPU frequency/power scaling improvements to enhance the Steam Play gaming experience on modern AMD platforms running Linux. Phoronix reports: It's no secret that the ACPI CPUFreq driver code has at times been less than ideal on recent AMD processors with delivering less than expected performance/behavior with being slow to ramp up to a higher performance state or otherwise coming up short of disabling the power management functionality outright. AMD hasn't traditionally worked on the Linux CPU frequency scaling code as much as Intel does to their P-State scaling driver and other areas of power management at large. AMD is ramping up efforts in these areas including around the Linux scheduler given their recent hiring spree while it now looks like thanks to the Steam Deck there is renewed interest in better optimizing the CPU frequency scaling under Linux. AMD and Valve have been working to improve the performance/power efficiency for modern AMD platforms running on Steam Play (Proton / Wine) and have spearheaded "[The ACPI CPUFreq driver] was not very performance/power efficiency for modern AMD platforms...a new CPU performance scaling design for AMD platform which has better performance per watt scaling on such as 3D game like Horizon Zero Dawn with VKD3D-Proton on Steam." AMD will be presenting more about this effort next month at XDC. It's quite possible this new effort is focused on ACPI CPPC support with the previously proposed AMD_CPUFreq. Back when Zen 2 launched in 2019, AMD did post patches for their new CPUFreq driver that leveraged ACPI Collaborative Processor Performance Controls but the driver was never mainlined nor any further iterations of the patches posted. When inquiring about that work a few times since then, AMD has always said it's been basically due to resource constraints that it wasn't a focus at that time. Upstream kernel developers also voiced their preference to seeing AMD work to improve the generic ACPI CPPC CPUFreq driver code rather than having another vendor-specific solution. It's also possible AMD has been working on better improvements around the now-default Schedutil governor for scheduler utilization data in making CPU frequency scaling decisions.

Yet another incident <https://arstechnica.com/gadgets/2021/07/with-help-from-google-impersonated-…> of substituting characters with different diacritic marks in a domain name to fool people into visiting the wrong site. Seems this problem is fundamentally unfixable. We need the ability to represent words in non-English languages, simply because the world does not revolve around the English language. And differences in meanings of words just from mixing up those diacritics can sometimes be quite major.

New Android Malware Records Smartphones via VNC To Steal Passwords

'Security researchers have discovered a novel piece of Android malware that uses the VNC technology to record and broadcast a victim's smartphone activity, allowing threat actors to collect keyboard presses and app passwords. From a report: First spotted in March 2021 by Dutch security firm ThreatFabric, this new piece of malware, named Vultur, is a departure from other Android malware strains that usually rely on fake login screens floating on top of legitimate apps to collect a victim's credentials. Instead, Vultur opens a VNC server on the infected phone, and broadcasts screen captures to an attacker command and control server, where the Vultur operator extracts passwords for desired apps.' -- source: https://it.slashdot.org/story/21/07/29/1549220 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Warnings That Work: Combating Misinformation Without Deplatforming
by Lawrence D'Oliveiro 29 Jul '21

29 Jul '21

How do you flag misleading postings on Facebook and elsewhere about vaccination, Covid-19 and other issues? Currently these platforms add a little warning next to the posting. Evidence accumulated over many years has shown that such “contextual” warnings are mostly disregarded. What does work is “interstitial” warnings: something that interrupts the user, and forces them to make a choice to continue. This works for security issues on PCs and when browsing the Internet; it can work for postings on social media, too. This article <https://freedom-to-tinker.com/2021/07/26/warnings-that-work-combating-misin…> goes into more details.

The Debian usrmerge Package
by Lawrence D'Oliveiro 27 Jul '21

27 Jul '21

There is a package in Debian (and no doubt also in its derivatives) called “usrmerge” <https://wiki.debian.org/UsrMerge>. The mere act of installing this will perform a “usr merge” on your system, which means that the contents of /bin are merged with /usr/bin, with the former becoming just a symlink to the latter, and similarly /sbin merged into /usr/sbin, and /lib merged into /usr/lib. Back in the last century, when hard drives were smaller, it was standard practice to put only the minimum core of executables and libraries into /bin, /sbin and /lib that would allow the system to boot into a state where a sysadmin could perform some basic maintenance tasks. All the less crucial, but nice to have stuff, would be in /usr, which would be mounted as a separate disk or partition. This way, I suppose, problems with the /usr volume could be fixed without the entire system becoming unbootable. These days, such a division is considered an anachronism. Debian hasn’t supported booting without /usr available for a long while now. I think some other distros, like Fedora, made the move a long time ago. And if you have problems with your OS partition, it’s easier to boot and fix things with something like SystemRescueCD anyway. Note that the usr merge, once performed, is not (easily) reversible. Also note that new Debian installs have been creating a merged usr system since version 10.

Microsoft Warns of 'Evolving' LemonDuck Mining Malware Targeting Linux and Windows Machines
by Peter Reutemann 26 Jul '21

26 Jul '21

'The threat intelligence team for Microsoft's 365 Defender security suite recently focused on an example of "modern mining malware infrastructure," describing how "Anything that can gain access to machines — even so-called commodity malware — can bring in more dangerous threats." Specifically, it offered a case study of LemonDuck. The blog post's title? "When coin miners evolve..." Today, beyond using resources for its traditional bot and mining activities, LemonDuck steals credentials, removes security controls, spreads via emails, moves laterally, and ultimately drops more tools for human-operated activity. LemonDuck's threat to enterprises is also in the fact that it's a cross-platform threat. It's one of a few documented bot malware families that targets Linux systems as well as Windows devices. It uses a wide range of spreading mechanisms — phishing emails, exploits, USB devices, brute force, among others — and it has shown that it can quickly take advantage of news, events, or the release of new exploits to run effective campaigns... Notably, LemonDuck removes other attackers from a compromised device by getting rid of competing malware and preventing any new infections by patching the same vulnerabilities it used to gain access... LemonDuck spreads in a variety of ways, but the two main methods are (1) compromises that are either edge-initiated or facilitated by bot implants moving laterally within an organization, or (2) bot-initiated email campaigns. LemonDuck acts as a loader for many other follow-on activities, but one if its main functions is to spread by compromising other systems. Since its first appearance, the LemonDuck operators have leveraged scans against both Windows and Linux devices for open or weakly authenticated SMB, Exchange, SQL, Hadoop, REDIS, RDP, or other edge devices that might be vulnerable to password spray or application vulnerabilities... Other common methods of infection include movement within the compromised environment, as well as through USB and connected drives. These processes are often kicked off automatically and have occurred consistently throughout the entirety of LemonDuck's operation.' -- source: https://linux.slashdot.org/story/21/07/25/2112228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Stops FTP Support in Firefox 90
by Peter Reutemann 25 Jul '21

25 Jul '21

'A post on Mozilla's security blog calls FTP "by now one of the oldest protocols still in use" — and it's suffering from "a number of serious security issues." The biggest security risk is that FTP transfers data in cleartext, allowing attackers to steal, spoof and even modify the data transmitted. To date, many malware distribution campaigns launch their attacks by compromising FTP servers and downloading malware on an end user's device using the FTP protocol. Aligning with our intent to deprecate non-secure HTTP and increase the percentage of secure connections, we, as well as other major web browsers, decided to discontinue support of the FTP protocol. Removing FTP brings us closer to a fully-secure web which is on a path to becoming HTTPS only and any modern automated upgrading mechanisms such as HSTS or also Firefox's HTTPS-Only Mode, which automatically upgrade any connection to become secure and encrypted do not apply to FTP. The FTP protocol itself has been disabled by default since version 88 and now the time has come to end an era and discontinue the support for this outdated and insecure protocol — Firefox 90 will no longer support the FTP protocol.' -- source: https://news.slashdot.org/story/21/07/24/0213220 There is always FileZilla: https://filezilla-project.org/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Researchers Found a Malicious NPM Package Using Chrome's Password-Recovery Tools
by Peter Reutemann 25 Jul '21

25 Jul '21

'Threatpost reports on "another vast software supply-chain attack" that was "found lurking in the npm open-source code repository...a credentials-stealing code bomb" that used the password-recovery tools in Google's Chrome web browser. Researchers caught the malware filching credentials from Chrome on Windows systems. The password-stealer is multifunctional: It also listens for incoming commands from the attacker's command-and-control (C2) server and can upload files, record from a victim's screen and camera, and execute shell commands... ReversingLabs researchers, who published their findings in a Wednesday post, said that during an analysis of the code repository, they found an interesting embedded Windows executable file: a credential-stealing threat. Labeled "Win32.Infostealer.Heuristics", it showed up in two packages: nodejs_net_server and temptesttempfile. At least for now, the first, main threat is nodejs_net_server. Some details: nodejs_net_server: A package with 12 published versions and a total of more than 1,300 downloads since it was first published in February 2019...finally upgrading it last December with a script to download the password-stealer, which the developer hosts on a personal website. It was subsequently tweaked to run TeamViewer.exe instead, "probably because the author didn't want to have such an obvious connection between the malware and their website," researchers theorized... ReversingLabs contacted the npm security team on July 2 to give them a heads-up about the nodejs_net_server and tempdownloadtempfile packages and circled back once again last week, on Thursday, since the team still hadn't removed the packages from the repository. When Threatpost reached out to npm Inc., which maintains the repository, a GitHub spokesperson sent this statement: "Both packages were removed following our investigation...."' -- source: https://developers.slashdot.org/story/21/07/24/0152218 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Reading about Firefox makes it seem a faster web browser than Chrome'

Spotted in New Scientist, who sadly paywall everything. 'Going into the test, people overall tended to view Chrome as faster than Firefox (~39 per cent to ~31 per cent). While the researchers noted that many participants brought their own strong brand preferences, priming participants had an effect that overcame the inertia of that affinity. "When respondents read one of the priming articles, we saw a prevalence of the priming effect over brand preferences, providing support for the hypothesis that Firefox is faster after reading about Firefox improvements," the researchers said.' https://www.theregister.com/2021/03/11/mozilla_google_speed/ https://arxiv.org/abs/2103.06181 <https://www.theregister.com/2021/03/11/mozilla_google_speed/> Cognitive psychology + UX/UI, nifty.

Do Software Bugs Really Cost 100× More To Fix In Production Than In Testing?
by Lawrence D'Oliveiro 23 Jul '21

23 Jul '21

There is an oft-cited claim that if you let a bug get into production code, the cost of fixing it increases a hundredfold, compared to if you had flushed it out during testing. This report <https://www.theregister.com/2021/07/22/bugs_expense_bs/> looks into the basis of that claim, and it seems to originate from a book published in 1987, which gave it a reference “[IBM81]”, which was “course notes at the IBM System Sciences Institute”. Only there was no such “Institute”, it seems it was really just the name for an internal training program for IBM employees. It also seems a related claim, that “defects cost more to fix the later you fix them”, also has weak, if any, empirical support. Nowhere in there is the issue of “technical debt” addressed, though. That is real, and can be very costly, and its costs do increase over time.

Google Pushed a One-Character Typo To Production, Bricking Chrome OS Devices
by Peter Reutemann 23 Jul '21

23 Jul '21

'Google says it has fixed a major Chrome OS bug that locked users out of their devices. Google's bulletin says that Chrome OS version 91.0.4472.165, which was briefly available this week, renders users unable to log in to their devices, essentially bricking them. From a report: Chrome OS automatically downloads updates and switches to the new version after a reboot, so users who reboot their devices are suddenly locked out them. The go-to advice while this broken update is out there is to not reboot. The bulletin says that a new build, version 91.0.4472.167, is rolling out now to fix the issue, but it could take a "few days" to hit everyone. Users affected by the bad update can either wait for the device to update again or "powerwash" their device -- meaning wipe all the local data -- to get logged in. Chrome OS is primarily cloud-based, so if you're not doing something advanced like running Linux apps, this solution presents less of an inconvenience than it would on other operating systems. Still, some users are complaining about lost data.' -- source: https://it.slashdot.org/story/21/07/22/1955245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

16-Year-Old HP Printer-Driver Bug Impacts Millions of Windows Machines
by Peter Reutemann 22 Jul '21

22 Jul '21

'Researchers have released technical details on a high-severity privilege-escalation flaw in HP printer drivers (also used by Samsung and Xerox), which impacts hundreds of millions of Windows machines. If exploited, cyberattackers could bypass security products; install programs; view, change, encrypt or delete data; or create new accounts with more extensive user rights. The bug (CVE-2021-3438) has lurked in systems for 16 years, researchers at SentinelOne said, but was only uncovered this year. It carries an 8.8 out of 10 rating on the CVSS scale, making it high-severity. According to researchers, the vulnerability exists in a function inside the driver that accepts data sent from User Mode via Input/Output Control (IOCTL); it does so without validating the size parameter. As the name suggests, IOCTL is a system call for device-specific input/output operations. "This function copies a string from the user input using 'strncpy' with a size parameter that is controlled by the user," according to SentinelOne's analysis, released on Tuesday. "Essentially, this allows attackers to overrun the buffer used by the driver." Thus, unprivileged users can elevate themselves into a SYSTEM account, allowing them to run code in kernel mode, since the vulnerable driver is locally available to anyone, according to the firm. The printer-based attack vector is perfect for cybercriminals, according to SentinelOne, since printer drivers are essentially ubiquitous on Windows machines and are automatically loaded on every startup. "Thus, in effect, this driver gets installed and loaded without even asking or notifying the user," explained the researchers. "Whether you are configuring the printer to work wirelessly or via a USB cable, this driver gets loaded. In addition, it will be loaded by Windows on every boot. This makes the driver a perfect candidate to target since it will always be loaded on the machine even if there is no printer connected." -- source: https://hardware.slashdot.org/story/21/07/21/2235207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Adding Custom Entries To A Create-New-Document Menu
by Lawrence D'Oliveiro 22 Jul '21

22 Jul '21

If you look at a file/folder view in various of the common GUI file managers, you should see a contextual menu item with a name like “Create New”, showing a submenu of different document types (e.g. “Text File...”, “Spread Sheet Document...”) that you can create in that location. Select an item, it asks you for a name for the new document, and it creates it under that name, as a copy of the template provided for that document type. You can then click to open the newly-created document in the corresponding app and continue working with it in the usual way. This is an alternative to launching the app, creating a new untitled document, then using its “Save-As” function to name the document file. Of course, you can easily create your own templates. On KDE, when I type kde4-config --path templates to find out where a KDE-based file manager like Dolphin finds these templates, it reports /home/ldo/.kde/share/templates/:/usr/share/templates/ The latter contains templates installed systemwide by repo packages, while the former can contain whatever I like. As to the format of these template files? They are just another variation on the ever-popular text-based .desktop file format, which is used for example to define entries in your application menu, and icons on the desktop (for those who like that sort of thing). Oddly, the official spec for this only briefly mentions <https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s06.ht…> “Type=Link”, without explaining this option further (that I can find). But some searching found this useful post <https://forum.kde.org/viewtopic.php?f=224&t=119342> on the KDE user forums. For example, if I look at /usr/share/templates/Illustration.desktop on my system, besides all the localized versions of the name to show for this option, there are the lines Type=Link URL=.source/Illustration.odg That “URL” is actually a file path relative to the .desktop file itself, referencing a document template to be copied as the initial state of the new document. Looking in the referenced directory, /usr/share/templates/.source/, I do indeed see the file Illustration.odg, along with many others. The association of the file extension with the app, in this case LibreOffice Draw, is handled through a separate spec, the shared MIME database <https://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec/>. This is also widely supported by GUI desktop environments.

PlasticArm is a 32-bit bendable processor
by Peter Reutemann 22 Jul '21

22 Jul '21

'Wearable electronics, like watches and fitness trackers, represent the next logical step in computing. They've sparked an interest in the development of flexible electronics, which could expand the category to include products like clothing and backpacks. Flexible electronics run into a problem, however: Our processing hardware is anything but flexible. Most efforts to deal with that limitation have involved splitting up processors into a collection of smaller units, linking them with flexible wiring, and then embedding all the components in a flexible polymer. To an extent, the process is a throwback to the early days of computing, when a floating-point unit might reside on a separate chip. But a group within the semiconductor company Arm has now managed to implement one of the company's smaller embedded designs using flexible silicon. The design works and executes all the instructions you'd expect from it, but it also illustrates the compromises we have to make to produce truly flexible electronics.' -- source: https://arstechnica.com/science/2021/07/researchers-build-a-bendable-arm-pr… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Audacity’s new owner is in another fight with the open source community
by Peter Reutemann 21 Jul '21

21 Jul '21

'Muse Group—owner of the popular audio-editing app Audacity—is in hot water with the open source community again. This time, the controversy isn't over Audacity—it's about MuseScore, an open source application which allows musicians to create, share, and download musical scores (especially, but not only, in the form of sheet music). The MuseScore app itself is licensed GPLv3, which gives developers the right to fork its source and modify it. One such developer, Wenzheng Tang ("Xmader" on GitHub) went considerably further than modifying the app—he also created separate apps designed to bypass MuseScore Pro subscription fees. After thoroughly reviewing the public comments made by both sides at GitHub, Ars spoke at length with Muse Group's Head of Strategy Daniel Ray—known on GitHub by the moniker "workedintheory"—to get to the bottom of the controversy.' -- source: https://arstechnica.com/gadgets/2021/07/audacitys-new-owner-is-in-another-f… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Nasty Linux Systemd Security Bug Revealed
by Peter Reutemann 21 Jul '21

21 Jul '21

'Qualys has discovered a new systemd security bug that enables any unprivileged user to cause a denial of service via a kernel panic. Slashdot reader inode_buddha shares the news via ZDNet's Steven J. Vaughan-Nichols: As Bharat Jogi, Qualys's senior manager of Vulnerabilities and Signatures, wrote, "Given the breadth of the attack surface for this vulnerability, Qualys recommends users apply patches for this vulnerability immediately." You can say that again. Systemd is used in almost all modern Linux distributions. This particular security hole arrived in the systemd code in April 2015. It works by enabling attackers to misuse the alloca() function in a way that would result in memory corruption. This, in turn, allows a hacker to crash systemd and hence the entire operating system. Practically speaking, this can be done by a local attacker mounting a filesystem on a very long path. This causes too much memory space to be used in the systemd stack, which results in a system crash. That's the bad news. The good news is that Red Hat Product Security and systemd's developers have immediately patched the hole.

Experimental Rust Support Patches Submitted to Linux Kernel Mailing List
by Peter Reutemann 21 Jul '21

21 Jul '21

'"The Rust for Linux project, sponsored by Google, has advanced..." reported the Register earlier this week: A new set of patches submitted to the Linux kernel mailing list summarizes the progress of the project to enable Rust to be used alongside C for implementing the Linux kernel. The progress is significant. - ARM and RISC-V architectures are now supported, thanks to work on rustc_codgen_gcc, which is a GCC codegen for rustc. This means that rustc does the initial compilation of Rust code but GCC (the GNU Compiler Collection) does the backend compilation, enabling support for the architectures that GCC supports... - Overall, "the Rust support is still to be considered experimental. However, as noted back in April, support is good enough that kernel developers can start working on the Rust abstractions for subsystems and write drivers and other modules," continued project leader Miguel Ojeda, a computer scientist at CERN in Geneva, Switzerland, now working full time on Rust for Linux... There is substantial support for the project across the industry. Google said in April "we feel that Rust is now ready to join C as a practical language for implementing the kernel" and that it would reduce the number of potential bugs and security vulnerabilities. Google is sponsoring Ojeda to work full time on the project for a year, via the ISRG (Internet Security Research Group), which said last month that it is part of "efforts to move the internet's critical software infrastructure to memory safe code," under the project name Prossimo. The ISRG is also the nonprofit organisation behind Let's Encrypt free security certificates. Ojeda also mentioned that Microsoft's Linux Systems Group is contributing and hopes to submit "select Hyper-V drivers written in Rust." Arm is promising assistance with Rust for Linux on ARM-based systems. IBM has contributed Rust kernel support for its PowerPC processor. More detail is promised at the forthcoming Linux Plumber's Conference in September. In the meantime, the project is on GitHub here. "In addition, we would like to announce that we are organizing a new conference that focuses on Rust and the Linux kernel..." Ojeda posted. "Details will be announced soon." And for context, the Register adds: Linus Torvalds has said on several occasions that he welcomes the possibility of using Rust alongside C for kernel development, and told IT Wire in April that it is "getting to the point where maybe it might be mergeable for 5.14 or something like that."' -- source: https://linux.slashdot.org/story/21/07/10/0447253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

DuckDuckGo Launches New Email Protection Service To Remove Trackers
by Peter Reutemann 21 Jul '21

21 Jul '21

'DuckDuckGo is launching a new email privacy service meant to stop ad companies from spying on your inbox. From a report: The company's new Email Protection feature gives users a free "@duck.com" email address, which will forward emails to your regular inbox after analyzing their contents for trackers and stripping any away. DuckDuckGo is also extending this feature with unique, disposable forwarding addresses, which can be generated easily in DuckDuckGo's mobile browser or through desktop browser extensions. The personal DuckDuckGo email is meant to be given out to friends and contacts you know, while the disposable addresses are better served when signing up for free trials, newsletters, or anywhere you suspect might sell your email address. If the email address is compromised, you can easily deactivate it. These tools are similar to anti-tracking features implemented by Apple in iOS 14 and iOS 15, but DuckDuckGo's approach integrates into iOS, Android, and all major web browsers. DuckDuckGo will also make it easier to spin up disposable email addresses on the fly, for newsletters or anywhere you might share your email.' -- source: https://yro.slashdot.org/story/21/07/20/1532258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

For years, a backdoor in popular KiwiSDR product gave root to project developer
by Peter Reutemann 20 Jul '21

20 Jul '21

'KiwiSDR is hardware that uses a software-defined radio to monitor transmissions in a local area and stream them over the Internet. A largely hobbyist base of users does all kinds of cool things with the playing-card-sized devices. For instance, a user in Manhattan could connect one to the Internet so that people in Madrid, Spain, or Sydney, Australia, could listen to AM radio broadcasts, CB radio conversations, or even watch lightning storms in Manhattan. On Wednesday, users learned that for years, their devices had been equipped with a backdoor that allowed the KiwiSDR creator—and possibly others—to log in to the devices with administrative system rights. The remote admin could then make configuration changes and access data not just for the KiwiSDR but in many cases to the Raspberry Pi, BeagleBone Black, or other computing devices the SDR hardware is connected to.' -- source: https://arstechnica.com/gadgets/2021/07/for-years-a-backdoor-in-popular-kiw… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hackers got past Windows Hello by tricking a webcam
by Peter Reutemann 20 Jul '21

20 Jul '21

'Biometric authentication is a key piece of the tech industry's plans to make the world password-less. But a new method for duping Microsoft's Windows Hello facial-recognition system shows that a little hardware fiddling can trick the system into unlocking when it shouldn't. Services like Apple's FaceID have made facial-recognition authentication more commonplace in recent years, with Windows Hello driving adoption even farther. Apple only lets you use FaceID with the cameras embedded in recent iPhones and iPads, and it's still not supported on Macs at all. But because Windows hardware is so diverse, Hello facial recognition works with an array of third-party webcams. Where some might see ease of adoption, though, researchers from the security firm CyberArk saw potential vulnerability. That's because you can't trust any old webcam to offer robust protections in how it collects and transmits data. Windows Hello facial recognition works only with webcams that have an infrared sensor in addition to the regular RGB sensor. But the system, it turns out, doesn't even look at RGB data. Which means that with one straight-on infrared image of a target's face and one black frame, the researchers found that they could unlock the victim's Windows Hello–protected device. By manipulating a USB webcam to deliver an attacker-chosen image, the researchers could trick Windows Hello into thinking the device owner’s face was present and unlocking.' -- source: https://arstechnica.com/information-technology/2021/07/hackers-got-past-win… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Case Against SQL
by Peter Reutemann 19 Jul '21

19 Jul '21

'Long-time Slashdot reader RoccamOccam shares "an interesting take on SQL and its issues from Jamie Brandon (who describes himself as an independent researcher who's built database engines, query planners, compilers, developer tools and interfaces). It's title? "Against SQL." The relational model is great... But SQL is the only widely-used implementation of the relational model, and it is: Inexpressive, Incompressible, Non-porous. This isn't just a matter of some constant programmer overhead, like SQL queries taking 20% longer to write. The fact that these issues exist in our dominant model for accessing data has dramatic downstream effects for the entire industry: - Complexity is a massive drag on quality and innovation in runtime and tooling - The need for an application layer with hand-written coordination between database and client renders useless most of the best features of relational databases The core message that I want people to take away is that there is potentially a huge amount of value to be unlocked by replacing SQL, and more generally in rethinking where and how we draw the lines between databases, query languages and programming languages... I'd like to finish with this quote from Michael Stonebraker, one of the most prominent figures in the history of relational databases: "My biggest complaint about System R is that the team never stopped to clean up SQL... All the annoying features of the language have endured to this day. SQL will be the COBOL of 2020..." It's been interesting to follow the discussion on Twitter, where the post's author tweeted screenshots of actual SQL code to illustrate various shortcomings. But he also notes that "The SQL spec (part 2 = 1732) pages is more than twice the length of the Javascript 2021 spec (879 pages), almost matches the C++ 2020 spec (1853) pages and contains 411 occurrences of 'implementation-defined', occurrences which include type inference and error propagation." His Twitter feed also includes a supportive retweet from Rust creator Graydon Hoare, and from a Tetrane developer who says "The Rust of SQL remains to be invented. I would like to see it come."' -- source: https://developers.slashdot.org/story/21/07/18/1844225 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

1.4 Million Cubans Bypass Censorship Using US Government-Funded Software Psiphon
by Peter Reutemann 19 Jul '21

19 Jul '21

'"Cuban officials rallied tens of thousands of supporters in the streets on Saturday — nearly a week after they were stunned by the most widespread protests in decades," the Associated Press reports. President Miguel Díaz-Canel — accompanied by 90-year-old former President Raul Castro — "made an impassioned speech blaming unrest on the U.S. and its economic embargo, 'the blockade, aggression and terror... The enemy has returned to throw all it has at destroying the sacred unity and tranquility of the citizens.'" "I think the government is just trying to signal to people that it understands their desperation and that it's going to try to alleviate some of the misery that they're experiencing. The problem is that the government just doesn't have much in the way of resources that it can devote to doing that," said William LeoGrande, an expert on Cuba at the American University in the United States. Meanwhile, Reuters reports: Psiphon Inc's freely available internet censorship circumvention tool has helped nearly 1.4 million Cubans this week gain access to websites, the company said on Friday, after Cuba's government curbed access to popular social media and messaging platforms... Thousands of Cubans joined nationwide protests over shortages of basic goods, limits on civil liberties and the government's handling of a surge in COVID-19 infections on Sunday, the most significant unrest in decades in the communist-run country. Psiphon said 1.389 million users accessed the open web from Cuba through its network on Thursday, as well as 1.238 million as noon EDT (1600 GMT) on Friday. "Internet is ON; circumvention tools ARE working," Psiphon said in a statement. Psiphon said the roughly 1.4 million represents about 20% of Cuban internet users. Its open source circumvention tool can be downloaded from app stores like Google Play or Apple to "maximize your chances of bypassing censorship," according to the company. Canadian university researchers developed the software in 2007 to let users evade governmental internet firewalls. The censorship-circumvention tool — which combines VPN, SSH, and HTTP Proxy tools — has also been used in Iran, China, Belarus, Myanmar, according to recent news reports. Bloomberg notes that the Toronto-based nonprofit Psiphon "has received funding from the Open Technology Fund, a U.S. government nonprofit that aims to support global internet freedom technologies... "On Thursday, President Biden said the U.S. is examining whether it's able to restore internet access shut down by the Cuban government."' -- source: https://yro.slashdot.org/story/21/07/18/009221 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Amazon's Elasticsearch Fork 'OpenSearch' Reaches General Availability 1.0 Milestone
by Peter Reutemann 19 Jul '21

19 Jul '21

'Mike Melanson's "This Week in Programming" column shares an update on Amazon's ongoing battle with scalable data search solution ElasticSearch: Earlier this year, AWS completed its fork of ElasticSearch with the first release of OpenSearch. If you haven't followed along, the whole affair was a bit of a tug of war between AWS and Elastic, with AWS eventually coming out seemingly on top. After Elastic changed the licensing on ElasticSearch in an attempt to prevent AWS from selling a service based on the then-open-source project, AWS forked the project to release OpenSearch under Apache 2.0, effectively preserving its open source status. Now, OpenSearch has reached 1.0, which AWS says not only "marks the first production-ready version of OpenSearch," but also introduces "multiple new enhancements," such as data streams, trace analytics span filtering, report scheduling and more. The 1.0 release also involved quite a bit of code cleanup, removing proprietary code and marks, and adds the ability to upgrade from ElasticSearch to OpenSearch as if you were performing a normal upgrade of ElasticSearch. If you're interested in learning where the project is going, head on over to the public roadmap to learn more.

Will a New Law Help the Chinese Government Stockpile Zero-Days?
by Peter Reutemann 19 Jul '21

19 Jul '21

'"Starting September 1, 2021, the Chinese government will require that any Chinese citizen who finds a zero-day vulnerability must pass the details to the Chinese government," reports SecurityWeek, "and must not sell or give the knowledge to any third-party outside of China (apart from the vulnerable product's manufacturer)." Brief details are provided in a report by the Associated Press (AP) published Tuesday, July 13, 2021. No source is provided beyond the statement, "No one may 'collect, sell or publish information on network product security vulnerabilities,' say the rules issued by the Cyberspace Administration of China and the police and industry ministries...." AP describes this action as "further tightening the Communist Party's control over information". This is unlikely to be the primary motivation for the new rule since the government already has a vice-like grip on data. Companies may not store data on Chinese customers outside of China. Foreign companies selling routers and some other network devices in China must disclose to regulators how any encryption features work. "I would expect the Chinese Government to weaponize any discovered security vulnerabilities to enhance China's cybersecurity capabilities," Joseph Carson, chief security scientist and advisory CISO at ThycoticCentrify, tells SecurityWeek. And Jake Williams, co-founder and CTO at BreachQuest adds that "the defensive advantages of Chinese government organizations being able to mitigate vulnerabilities discovered may well outweigh any offensive gains...." But he also believes this could rebound against China. "One of the biggest likely issues is brain drain. If Chinese researchers can profit handsomely from their work anywhere else, but can't do so in China, why would they stay? This probably helps China in the short term but harms them in the long term." The new law does encourage network operators and product vendors to set up a reward mechanism for reported vulnerabilities, according to the Record. But Katie Moussouris, founder and CEO of Luta Security, also raises the issue of western-based bug bounty platforms that have been working with Chinese security researchers for the past years. "If Western-based bug bounty platforms comply with this requirement in order to continue to legally receive bug reports from Chinese researchers, we must assume they will be required to hand over vulnerability data to the Ministry within two days of receiving the reports," Moussouris said. "That requirement will effectively introduce a backdoor straight to the Chinese government in any VDP [vulnerability disclosure program] or bug bounty program where Chinese researchers submit bugs via platforms, even to non-Chinese companies."' -- source: https://it.slashdot.org/story/21/07/18/2143207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

"I have 10 such devices in the house which includes smart speakers, smart displays and Chromecast which all respond to the advert," they write. "This is not only highly annoying, but also a deliberate attempt to trigger these devices." Yes, it seems it really does happen ...

Libre-SOC's Open Hardware 180nm ASIC Submitted To IMEC for Fabrication

Oh and here, have the source code." And now there's big news, reports long-time Slashdot reader lkcl: Libre-SOC's entirely Libre 180nm ASIC, which can be replicated down to symbolic level GDS-II with no NDAs of any kind, has been submitted to IMEC for fabrication. It is the first wholly-independent Power ISA ASIC outside of IBM to go Silicon in 12 years. Microwatt went to Skywater 130nm in March; however, it is also developed by IBM, as an exceptionally well-made Reference Design, which Libre-SOC used for verification. Whilst it would seem that Libre-SOC is jumping on the chip-shortage era's innovation bandwagon, Libre-SOC has actually been in development for over three and a half years so far. It even pre-dates the OpenLane initiative, and has the same objectives: fully automated HDL to GDS-II, full transparency and auditability with Libre VLSI tools Coriolis2 and Libre Cell Libraries from Chips4Makers. With €400,000 in funding from the NLNet Foundation [a long-standing non-profit supporting privacy, security, and the "open internet"], plus an application to NGI Pointer under consideration, the next steps are to continue development of Draft Cray-style Vectors (SVP64) to the already supercomputer-level Power ISA, under the watchful eye of the upcoming OpenPOWER ISA Workgroup.' -- source: https://hardware.slashdot.org/story/21/07/10/0154220 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Edge Beats Firefox To Become the Third-Most Popular Browser
by Peter Reutemann 11 Jul '21

11 Jul '21

'"New data from Statcounter shows that Edge has now overtaken established rival Firefox in the rankings," reports TechRadar: In recent months, the pair have been neck-and-neck, but Microsoft's browser has now put daylight between itself and Firefox. Figures for June suggest Microsoft Edge now holds 3.4% of the browser market, while Firefox has slipped to 3.29%, continuing a downward trajectory that has seen the browser either lose or maintain market share in ten of the last twelve months. The change pushes Edge into third position in the browser rankings, behind only Chrome (65.27%) and Safari (18.34%). Launched in January 2020, the new Chromium-based Edge got off to a slow start, but began to gather momentum as the year progressed. Since last summer, the browser's market share has more than tripled. The increase in adoption can be attributed in part to renewed marketing efforts, but also to improvements that brought the experience in line with other modern web browsers. That may be true, but the article also acknowledges that it was just last month that Microsoft began rolling out Edge to all Windows PCs (via Windows 10 updates), "expanding the install base by millions almost overnight. "Now, Microsoft is doing everything in its power to encourage users to abandon Internet Explorer in favor of Edge, such as removing support for Microsoft 365 web apps and automatically launching certain web pages in the new browser."' -- source: https://news.slashdot.org/story/21/07/10/0353201 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google's Unfair Performance Advantage in Chrome
by Peter Reutemann 10 Jul '21

10 Jul '21

'Google Chrome for Android has a feature that gives Google Search an unfair advantage over its competition. Sure, it's the default search engine and that's a huge hurdle to overcome for any competitor. However, Chrome also reserves a performance-boosting feature for Google Search exclusively. I recently poked around in the Chromium project source code; the open-source foundation for Google's Chrome web browser. The Chromium project is co-developed by Google, and other corporate and individual contributors. The project is managed and controlled by Google, however. I was looking for something else when I stumbled upon a feature called PreconnectToSearch. When enabled, the feature preemptively opens and maintains a connection to the default search engine. The preconnection feature resolves the domain name, and negotiates and sets up a secure connection to the server. All these things take time and they must happen before the search engine can receive the users' search queries. Preempting these steps can save a dozen seconds on a slow network connection or half a second on a fast connection. This optimization can yield a nice performance boost for Google's customers. Assuming the connection only requires a trivial amount of processing power and network bandwidth, of course. Setting up the connection early can be wasteful or slow down the loading of other pages if the user isn't going to search the web. There's just one small catch: Chromium checks the default search engine setting, and only enables the feature when it's set to Google Search. This preferential treatment means no other search engine can compete with Google Search on the time it takes to load search results. Every competitor must wait until the user has started to type a search query before Chrome will establish a connection.' -- source: https://tech.slashdot.org/story/21/07/09/2056209 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox Extends Privacy and Security of Canadian Internet Users With By-default DNS-over-HTTPS Rollout in Canada
by Peter Reutemann 09 Jul '21

09 Jul '21

'In a few weeks, Firefox will start the by-default rollout of DNS over HTTPS (or DoH for short) to its Canadian users in partnership with local DoH provider CIRA, the Canadian Internet Registration Authority. >From a report: DoH will first become a default for 1% of Canadian Firefox users on July 20 and will gradually reach 100% of Canadian Firefox users in late September 2021 -- thereby further increasing their security and privacy online. This follows the by-default rollout of DoH to US users in February 2020. As part of the rollout, CIRA joins Mozilla's Trusted Recursive Resolver (TRR) Program and becomes the first internet registration authority and the first Canadian organization to provide Canadian Firefox users with private and secure encrypted Domain Name System (DNS) services.' -- source: https://news.slashdot.org/story/21/07/08/1732203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Kaspersky Password Manager Fixes Flaw That Generated Easily Bruteforced Passwords
by Peter Reutemann 09 Jul '21

09 Jul '21

'ZDNet reports: Suppose you are in the business of generating passwords, it would probably be a good idea to use an additional source of entropy other than the current time, but for a long time, that's all Kaspersky Password Manager (KPM) used. In a blog post to cap off an almost two year saga, Ledger Donjon head of security research Jean-Baptiste Bedrune showed KPM was doing just that. "Kaspersky Password Manager used a complex method to generate its passwords. This method aimed to create passwords hard to break for standard password crackers. However, such method lowers the strength of the generated passwords against dedicated tools," Bedrune wrote. One of the techniques used by KPM was to make letters that are not often used appear more frequently, which Bedrune said was probably an attempt to trick password cracking tools. "Their password cracking method relies on the fact that there are probably 'e' and 'a' in a password created by a human than 'x' or 'j', or that the bigrams 'th' and 'he' will appear much more often than 'qx' or 'zr'," he said. "Passwords generated by KPM will be, on average, far in the list of candidate passwords tested by these tools. If an attacker tries to crack a list of passwords generated by KPM, he will probably wait quite a long time until the first one is found. This is quite clever." The flip side was that if an attacker could deduce that KPM was used, then the bias in the password generator started to work against it. "If an attacker knows a person uses KPM, he will be able to break his password much more easily than a fully random password. Our recommendation is, however, to generate random passwords long enough to be too strong to be broken by a tool." The big mistake made by KPM though was using the current system time in seconds as the seed into a Mersenne Twister pseudorandom number generator. "It means every instance of Kaspersky Password Manager in the world will generate the exact same password at a given second," Bedrune said. Because the program has an animation that takes longer than a second when a password is created, Bedrune said it could be why this issue was not discovered. "The consequences are obviously bad: every password could be bruteforced," he said. Bedrune added due to sites often showing account creation time, that would leave KPM users vulnerable to a bruteforce attack of around 100 possible passwords. "Kaspersky was informed of the vulnerability in June 2019, and released the fix version in October that same year," adds ZDNet. "In October 2020, users were notified that some passwords would need to be generated, with Kaspersky publishing its security advisory on 27 April 2021." "All public versions of Kaspersky Password Manager liable to this issue now have a new logic of password generation and a passwords update alert for cases when a generated password is probably not strong enough," the security company said.' -- source: https://it.slashdot.org/story/21/07/08/2116252 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Endian Wars: Linus Has Spoken
by Lawrence D'Oliveiro 06 Jul '21

06 Jul '21

The Rust language continues to make progress for use in the Linux kernel <https://www.theregister.com/2021/07/05/rust_for_linux_kernel_project/>. The article ends with a comment from Linus Torvalds about the old “endian wars” which have been a feature of the computing landscape since byte addressability became common: should the bytes of a number be arranged in big-endian order (most significant end at the lowest address) or little-endian (least significant end at the lowest address)? In the latest patches, Ojeda proposed to use big-endian order for long symbols in the kernel symbol table, needed because Rust symbols "can become quite long due to namespacing introduced by modules, types, traits, generics." Torvalds responded: "Why is this in big-endian order? Let's just try to kill big-endian data, it's disgusting and should just die already... networking has legacy reasons from the bad old days when byte order wars were still a thing, but those days are gone." Having used both kinds of computer architectures over the years, I agree. Little-endian ordering is more mathematically consistent.

Infinidash: The Most Amazing Amazon Web Services Product ... That Never Was
by Lawrence D'Oliveiro 05 Jul '21

05 Jul '21

It all started with one person wondering how long it would take after merely mentioning the name of some hypothetical new AWS-based product before it started appearing in job ads. So he made up a product name, put out a tweet, and waited. It took just three days <https://www.theregister.com/2021/07/05/infinidash/>. I had a look at the linked job ad, and it still contains the sentence “Infinidash is at the core of everything we do”, with absolutely no hint that it might be tongue-in-cheek. This is just a continuation of the long-standing phenomenon among HR departments and employment agencies putting out job ads requiring something like “5+ years experience in Technology X”, when Technology X has only been around for a few months.

Word Of The Week: “Footgun”
by Lawrence D'Oliveiro 30 Jun '21

30 Jun '21

You know the phrase “shooting yourself in the foot” -- wielding a tool or capability with great power that, if not used carefully, has great capacity to cause harm, to the wielder and others. A “footgun” is a (mis)feature of some system that makes it more likely that this will happen. You thought security was an intrinsic feature of the container concept? Well, it seems <https://www.theregister.com/2021/06/29/newsblur_docker_ransomware/> Docker has long had an oddly insecure default setting, where network ports on a container are automatically punched through your kernel’s firewall settings, allowing access from the entire Internet. This is often not what you want.

Python Implementation Pyston Aims To Speed Up the Programming Language's Code for Web Applications
by Peter Reutemann 30 Jun '21

30 Jun '21

'When Kevin Modzelewski and his colleagues at Dropbox set out to create Pyston in 2014, they had a very simple objective: to lower the costs of running Python code on Dropbox's servers, by making the code itself faster. "We were growing exponentially, so our server cost was growing exponentially," Modzelewski tells TechRepublic. "If we could get Python running faster, we would spend less money running Python." The original cost reduction initiative at Dropbox snowballed into a bigger project for Modzelewski when the company moved away from Python in 2017 and cancelled the Pyston project. He had realized while working on the language that there was a strong demand for faster Python among the developer community, and while there were plenty of tools around for improving the performance in smaller applications, there were none designed for big, business logic-type applications such as Dropbox. "There's a lot of tools out there for helping you run Python faster, but there weren't any that were a good fit for Dropbox's use case," says Modzelewski. "This was an area of the Python market where a lot of money was being spent, but not very many tools were being developed for helping. It was under served." Fast forward to today and Pyston is now in version 2.2, and has been open-sourced, with Modzelewski and fellow developer Marius Wachtler now leading the project as co-founders. The latest implementation promises a 30% performance improvement over Python 3.8.8, with a key benefit being that developers can simply drop their Python applications into Pyston and get going, without having to rewrite their code. It's also a "completely separate thing" to what Modzelewski and fellow developers built for Dropbox some seven years ago.' -- source: https://developers.slashdot.org/story/21/06/29/195244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Inside Neeva, the Ad-Free, Privacy-First Search Engine From ex-Googlers
by Peter Reutemann 30 Jun '21

30 Jun '21

'Sridhar Ramaswamy and Vivek Raghunathan helped turn Google into an ad giant. Now they're starting over with a service whose only customers are its users. From a report: A new search engine? One that people have to pay to use? At first blush, it may seem like a textbook example of a startup idea destined never to get anywhere. By definition, any new search engine competes with Google, whose 90 percent-plus market share leaves little oxygen for other players. And we've been accustomed to getting our search for free since well before there was a Google -- which might make paying for it sound like being expected to purchase a phone book. But Neeva is indeed a new search engine, officially launching today, that carries a subscription fee. Though it's extremely similar to Google in many respects -- with a few twists of its own -- it dumps the web giant's venerable ad-based business model in the interest of avoiding distractions, privacy quandaries, and other compromises. It's free for three months -- long enough for users to grow accustomed to it without obligation -- and $4.95 a month thereafter. Apps for iPhones and iPads, and browser extensions for Chrome, Firefox, Safari, Edge, and Brave, are part of the deal. Neeva may have a certain whiff of improbability about it, but its cofounders, Sridhar Ramaswamy and Vivek Raghunathan, are the furthest thing from naifs. Two long-time Google executives with more than a quarter-century of experience at the web giant between them, they have an insider's understanding of how it operates. Moreover, about 30 percent of the roughly 60-person staff they've assembled at Neeva consists of ex-Googlers, including Hall-of-Famers such as Udi Manber (a former head of Google search) and Darin Fisher (one of the inventors of Chrome). They've also secured $77.5 million in funding, including investments from venture-capital titans Greylock and Sequoia.' -- source: https://yro.slashdot.org/story/21/06/29/2017205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hubble Computer Trouble
by Lawrence D'Oliveiro 29 Jun '21

29 Jun '21

The Hubble Space Telescope is currently out of action, seemingly from a computer-related fault, though booting up the backup computer hasn’t made a difference (so far). In the meantime, here <https://www.theregister.com/2021/06/28/hubbles_cosmic_science_is_mindblowin…> is a retrospective on how that outermost of our sky-seeing eyes came to be, and what it has achieved. Born out of repurposed parts from an unneeded spy satellite? You might think that; those who know couldn’t possibly comment ... By the way, this description of the fault with the mirror And oh yes, that mirror. Younger readers won’t recall the shock at first light when a tiny mistake in its shape made the star of the show useless. Nobody’s saying how many spybirds were similarly afflicted, but where it mattered the most, Hubble was blind. is wrong. Hubble wasn’t blind, it was merely short-sighted. Those pictures that were supposed to have more detail than anything achievable from ground level were only fair-to-middling. I remember a visit to Waikato University in the early 1990s from a researcher in the US who was part of a team that was modelling the blurring effect of the mirror aberration, and applying it in reverse to sharpen up the images to something resembling the quality they were supposed to have. I think they were achieving some useful results. Eventually, of course, their work became unnecessary, as that wonder of eyeglass contraptions called COSTAR was installed.

Intel To Disable TSX By Default On More CPUs With New Microcode
by Peter Reutemann 29 Jun '21

29 Jun '21

'Intel is going to be disabling Transactional Synchronization Extensions (TSX) by default for various Skylake through Coffee Lake processors with forthcoming microcode updates. Phoronix reports: Transactional Synchronization Extensions (TSX) have been around since Haswell for hardware transactional memory support and going off Intel's own past numbers can be around 40% faster in specific workloads or as much 4~5 times faster in database transaction benchmarks. TSX issues have been found in the past such as a possible side channel timing attack that could lead to KASLR being defeated and CVE-2019-11135 (TSX Async Abort) for an MDS-style flaw. Now in 2021 Intel is disabling TSX by default across multiple families of Intel CPUs from Skylake through Coffee Lake. [...] The Linux kernel is preparing for this microcode change as seen in the flow of new patches this morning for the 5.14 merge window. A memory ordering issue is what is reportedly leading Intel to now deprecate TSX on various processors. There is this Intel whitepaper (PDF) updated this month that outlines the problem at length. As noted in the revision history, the memory ordering issue has been known to Intel since at least before October 2018 but only now in June 2021 are they pushing out microcode updates to disable TSX by default. With forthcoming microcode updates will effectively deprecate TSX for all Skylake Xeon CPUs prior to Stepping 5 (including Xeon D and 1st Gen Xeon Scalable), all 6th Gen Xeon E3-1500m v5 / E3-1200 v5 Skylake processors, all 7th/8th Gen Core and Pentium Kaby/Coffee/Whiskey CPUs prior to 0x8 stepping, and all 8th/9th Gen Core/Pentium Coffee Lake CPUs prior to 0xC stepping will be affected. That ultimately spans from various Skylake steppings through Coffee Lake; it was with 10th Gen Comet Lake and Ice Lake where TSX/TSX-NI was subsequently removed. In addition to disabling TSX by default and force-aborting all RTM transactions by default, a new CPUID bit is being enumerated with the new microcode to indicate that the force aborting of RTM transactions. It's due to that new CPUID bit that the Linux kernel is seeing patches. Previously Linux and other operating systems applied a workaround for the TSX memory ordering issue but now when this feature is disabled, the kernel can drop said workaround. These patches are coming with the Linux 5.14 cycle and will likely be back-ported to stable too.' -- source: https://hardware.slashdot.org/story/21/06/28/205240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Foundation's New 'OVN Network' Pushes Open Standards for AI-Powered Voice Apps
by Peter Reutemann 29 Jun '21

29 Jun '21

'"Organizations are beginning to develop, design, and manage their own AI-powered voice assistant systems independent of platforms such as Siri and Alexa," reports VentureBeat: The transition is being driven by the desire to manage the entirety of the user experience and integrate voice assistance into multiple business processes and brand environments, from call centers to stores. In a recent survey of 500 IT and business decision-makers in the U.S., France, Germany, and the U.K., 28% of respondents said they were using voice technologies and 84% expect to be using them in the next year. To support the evolution, the Linux Foundation launched the Open Voice Network (OVN), an alliance advocating for the adoption of open standards across voice assistant apps in automobiles, smartphones, smart home devices, and more. With founding members Target, Schwarz Gruppe, Wegmans Food Markets, Microsoft, Veritone, Deutsche Telekom, and others, the OVN's goal — much like Amazon's Voice Interoperability Initiative — is to standardize the development and use of voice assistant systems and conversational agents that use technologies including automatic speech recognition, natural language processing, advanced dialog management, and machine learning... It was first announced as the Open Voice Initiative in 2019, but expanded significantly as the COVID-19 pandemic spurred enterprises to embrace digital transformation. "Voice is expected to be a primary interface to the digital world, connecting users to billions of sites, smart environments and AI bots ... Key to enabling enterprise adoption of these capabilities and consumer comfort and familiarity is the implementation of open standards," Mike Dolan, SVP and general manager of projects at the Linux Foundation, said in a statement. "The potential impact of voice on industries including commerce, transportation, healthcare, and entertainment is staggering and we're excited to bring it under the open governance model of the Linux foundation to grow the community and pave a way forward." Besides a focus on standards and technology-sharing, the group plans to collaborate with existing industry associations on regulatory/legislative issues — including data privacy."' -- source: https://news.slashdot.org/story/21/06/28/0051204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Using VMs To Hide Ransomware Attacks is Becoming More Popular
by Peter Reutemann 29 Jun '21

29 Jun '21

'In early 2020, security researchers were baffled to discover that a ransomware gang had come up with an innovative trick that allowed it to run its payload inside virtual machines on infected hosts as a technical solution that bypassed security software. One year later, that technique has spread among the cybercrime underground and is now used by multiple ransomware operators. Initially seen with the Ragnar Locker gang in May 2020, the technique was also adopted by a Maze ransomware subgroup later in the year and has been recently spotted in attacks where the Conti and MountLocker ransomware strains were deployed. In hindsight, it should be no surprise that this technique is becoming more popular, as it has tangible benefits for any threat actor. The general idea behind such an attack is that a ransomware gang that has a small foothold on an infected host can download and install VM software. The ransomware gang will then start a VM instance, share the host computer's storage space with the VM, and then proceed to encrypt the victim's files from within the VM, where the host's antivirus software cannot reach and detect the ransomware during execution.' -- source: https://it.slashdot.org/story/21/06/28/1521220 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Engineer Confirms You Can Sideload Android APKs On Windows 11
by Peter Reutemann 27 Jun '21

27 Jun '21

'Famed software engineer Miguel de Icaza confirmed on Twitter that you will be able to sideload Android APKs in Windows 11. Android Authority reports: Yesterday, Microsoft surprised us all by announcing that Windows 11 will support native Android app installation. Using the Microsoft Store, you'll be able to search for, install, and use Android apps right on your PC. This is possible through an integration of the Amazon App Store. However, a big question loomed over the announcement: would you be able to sideload Android APKs on Windows 11? Sideloading apps would allow you to install Android programs from outside the Microsoft Store, which would give you a much larger potential library. It seems the answer to that question is "yes," at least according to famed engineer Miguel de Icaza.

Dell SupportAssist Bugs Put Over 30 Million PCs At Risk
by Peter Reutemann 27 Jun '21

27 Jun '21

'Security researchers have found four major security vulnerabilities in the BIOSConnect feature of Dell SupportAssist, allowing attackers to remotely execute code within the BIOS of impacted devices. According to Dell's website, the SupportAssist software is 'preinstalled on most Dell devices running Windows operating system,' while BIOSConnect provides remote firmware update and OS recovery features. The chain of flaws discovered by Eclypsium researchers comes with a CVSS base score of 8.3/10 and enables privileged remote attackers to impersonate Dell.com and take control of the target device's boot process to break OS-level security controls. "Such an attack would enable adversaries to control the device's boot process and subvert the operating system and higher-layer security controls," Eclypsium researchers explain in a report shared in advance with BleepingComputer. "The issue affects 129 Dell models of consumer and business laptops, desktops, and tablets, including devices protected by Secure Boot and Dell Secured-core PCs," with roughly 30 million individual devices exposed to attacks.' -- source: https://it.slashdot.org/story/21/06/25/176208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

NFC Flaws Let Researchers Hack an ATM By Waving a Phone
by Peter Reutemann 27 Jun '21

27 Jun '21

'Ars Technica reports: For years, security researchers and cybercriminals have hacked ATMs by using all possible avenues to their innards, from opening a front panel and sticking a thumb drive into a USB port to drilling a hole that exposes internal wiring. Now, one researcher has found a collection of bugs that allow him to hack ATMs -- along with a wide variety of point-of-sale terminals -- in a new way: with a wave of his phone over a contactless credit card reader. Josep Rodriguez, a researcher and consultant at security firm IOActive, has spent the last year digging up and reporting vulnerabilities in the so-called near-field communications reader chips used in millions of ATMs and point-of-sale systems worldwide. NFC systems are what let you wave a credit card over a reader -- rather than swipe or insert it -- to make a payment or extract money from a cash machine. You can find them on countless retail store and restaurant counters, vending machines, taxis, and parking meters around the globe. Now Rodriguez has built an Android app that allows his smartphone to mimic those credit card radio communications and exploit flaws in the NFC systems' firmware. With a wave of his phone, he can exploit a variety of bugs to crash point-of-sale devices, hack them to collect and transmit credit card data, invisibly change the value of transactions, and even lock the devices while displaying a ransomware message. Rodriguez says he can even force at least one brand of ATMs to dispense cash -- though that "jackpotting" hack only works in combination with additional bugs he says he has found in the ATMs' software. He declined to specify or disclose those flaws publicly due to nondisclosure agreements with the ATM vendors. "You can modify the firmware and change the price to one dollar, for instance, even when the screen shows that you're paying 50 dollars. You can make the device useless, or install a kind of ransomware. There are a lot of possibilities here," says Rodriguez of the point-of-sale attacks he discovered. "If you chain the attack and also send a special payload to an ATM's computer, you can jackpot the ATM -- like cash out, just by tapping your phone." Rodriguez says he alerted the affected vendors -- which include ID Tech, Ingenico, Verifone, Crane Payment Innovations, BBPOS, Nexgo, and the unnamed ATM vendor -- to his findings between seven months and a year ago. Even so, he warns that the sheer number of affected systems and the fact that many point-of-sale terminals and ATMs don't regularly receive software updates -- and in many cases require physical access to update -- mean that many of those devices likely remain vulnerable. "Patching so many hundreds of thousands of ATMs physically, it's something that would require a lot of time," Rodriguez says.' -- source: https://it.slashdot.org/story/21/06/25/2049217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Admits to Mistakenly Signing a Malicious Malware Rootkit
by Peter Reutemann 27 Jun '21

27 Jun '21

'Bleeping Computer reports: Microsoft has now confirmed signing a malicious driver being distributed within gaming environments. This driver, called "Netfilter," is in fact a rootkit that was observed communicating with Chinese command-and-control IPs. G Data malware analyst Karsten Hahn first took notice of this event last week and was joined by the wider infosec community in tracing and analyzing the malicious drivers bearing the seal of Microsoft... This incident has once again exposed threats to software supply-chain security, except this time it stemmed from a weakness in Microsoft's code-signing process. G Data writes: We forwarded our findings to Microsoft who promptly added malware signatures to Windows Defender and are now conducting an internal investigation. At the time of writing it is still unknown how the driver could pass the signing process. In a Friday blog post, Microsoft said it was contacting other antivirus software vendors "so they can proactively deploy detections," but also emphasized the attack's limited scope: The actor's activity is limited to the gaming sector specifically in China and does not appear to target enterprise environments. We are not attributing this to a nation-state actor at this time. The actor's goal is to use the driver to spoof their geo-location to cheat the system and play from anywhere. The malware enables them to gain an advantage in games and possibly exploit other players by compromising their accounts through common tools like keyloggers. It's important to understand that the techniques used in this attack occur post exploitation, meaning an attacker must either have already gained administrative privileges in order to be able to run the installer to update the registry and install the malicious driver the next time the system boots or convince the user to do it on their behalf. We will be sharing an update on how we are refining our partner access policies, validation and the signing process to further enhance our protections. There are no actions customers should take other than follow security best practices and deploy Antivirus software such as Windows Defender for Endpoint.' -- source: https://it.slashdot.org/story/21/06/26/1918225 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Open Source AMD FidelityFX Super Resolution Impresses In PC Game Tests
by Peter Reutemann 24 Jun '21

24 Jun '21

'AMD's FidelityFX Super Resolution (FSR) PC graphics up-scaling technology is ready for prime-time and the company has allowed members of the press to showcase performance and visuals of the tech in action with a number of game engines. AMD FidelityFX Super Resolution is vendor-agnostic and doesn't require specialized hardware to function like NVIDIA DLSS, which relies on Tensor cores on-board NVIDIA Turing or Ampere GPUs to accelerate neural network models that have been specifically trained on game engines. In contrast, AMD FSR utilizes more traditional spatial upscaling to create a super resolution image from a single input frame, not multiple frames. AMD FSR then employs a library of open-source algorithms that work on sharpening both image edge and texture detail. In game testing at HotHardware, frame rates can jump dramatically with little to no perceptible reduction in image quality, and the technology even works on many NVIDIA GPUs as well. There are currently 19 titles that are available or planned with support for AMD FSR, but with the open nature of the technology and cross-GPU compatibility, game developers theoretically should have significant incentive for adoption to breath new performance into their game titles.' -- source: https://tech.slashdot.org/story/21/06/22/217251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox Begins Testing Sponsors on Some Users' Default Home Page/New Tab Pages
by Peter Reutemann 21 Jun '21

21 Jun '21

'Earlier this year a new support page appeared at support.Mozilla.org describing sponsored shortcuts (or sponsored tiles), "an experimental feature currently being tested by a small percentage of Firefox users in a limited number of markets." Mozilla works with advertising partners to place sponsored tiles on the Firefox default home page (or New Tab page) that would be useful to Firefox users. Mozilla is paid when users click on sponsored tiles.... [W]e only work with advertising partners that meet our privacy standards for Firefox. When you click on a sponsored tile, Firefox sends anonymized technical data to our partner through a Mozilla-owned proxy service. The code for this proxy service is available on GitHub for interested technical audiences. This data does not include any personally identifying information and is only shared when you click on a Sponsored shortcut.... You can disable a specific Sponsored tile... You can also disable Sponsored shortcuts altogether. Describing the as-yet-experimental feature, Engadget wrote a story headlined "Don't freak out: Firefox is testing advertisements in new tabs." These are just the tests, still mainly aimed at fresh installs of the Firefox web browser and always to beta users, before the rollout of sponsored tiles. It does sound like adverts are in the pipe, but it depends on the reaction to Mozilla's initial tests. Mozilla's Jonathan Nightingale says that, last time around, the reaction wasn't as positive as his company hoped. "It didn't go over well," he states. Further, he insists that Firefox won't become "a mess of logos sold to the highest bidder; without user control, without user benefit." Long-time Slashdot reader angryargus says they spotted the feature when they noticed an Ebay advertisement, but appreciated the ability to opt out, and suggested the feature is "an annoying tradeoff off using a browser that's not as directly funded by a search engine."' -- source: https://news.slashdot.org/story/21/06/20/0153218 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Open Standard But Not Open Access: Schematron Author Complains About ISO Paywall
by Lawrence D'Oliveiro 19 Jun '21

19 Jun '21

Not the first time this has happened <https://www.theregister.com/2021/06/18/schematron_standard_paywall/>: a group volunteers to create an open standard, giving freely of their time, get it widely adopted, hand it over to a standards body like ISO to make it “official”, and the latter starts charging for copies of the spec. Note this response from ISO: "Unfortunately, the ISO Central Secretariat does not provide free copies of standards. All ISO Publications derive from the work and contributions of ISO and ISO Members that contain intellectual property of demonstrable economic value.” And how much did ISO pay those contributors for that “intellectual property”? Not a penny.

Microsoft’s Linux repositories were down for 18+ hours
by Peter Reutemann 19 Jun '21

19 Jun '21

'Yesterday, packages.microsoft.com—the repository from which Microsoft serves software installers for Linux distributions including CentOS, Debian, Fedora, OpenSUSE, and more—went down hard, and it stayed down for around 18 hours. The outage impacted users trying to install .NET Core, Microsoft Teams, Microsoft SQL Server for Linux (yes, that's a thing) and more—as well as Azure's own devops pipelines. We first became aware of the problem Wednesday evening when we saw 404 errors in the output of apt update on an Ubuntu workstation with Microsoft Teams installed. The outage is somewhat better-documented at this .NET Core issue report on Github, with many users from all around the world sharing their experiences and theories. The short version is that the entire repository cluster that serves all Linux packages for Microsoft was completely down—issuing a range of HTTP 404 (content not found) and 500 (Internal Server Error) messages for any URL—for roughly 18 hours. Microsoft engineer Rahul Bhandari confirmed the outage roughly five hours after it was initially reported, with a cryptic comment about the infrastructure team "running into some space issues." Eighteen hours after the issue was detailed, Bhandari said that the mirrors were once again available—although with temporarily degraded performance, likely due to cold caches. In this update, Bhandari said that the original cause of the outage was "a regression in [apt repositories] during some feature migration work that resulted in those packages becoming unavailable on the mirrors." We're still waiting for a comprehensive incident report, since Bhandari's status updates provide clues but no real explanations. The good news: We can confirm that packages.microsoft.com is indeed up once again, and it is serving packages as it should.' -- source: https://arstechnica.com/gadgets/2021/06/microsofts-linux-repositories-were-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Smart Contract: Computer Says No
by Lawrence D'Oliveiro 18 Jun '21

18 Jun '21

Another day, another tale of cryptocurrency failure <https://www.theregister.com/2021/06/17/iron_cryptocoin_titan/>. What’s different about this one is that it involved a “stablecoin”, which is some kind of attempt to reduce the volatility of a cryptocurrency by tying it in part to an actual currency. Note this linkage was only partial, and also involved a “smart contract”. This is a piece of autonomous code that, once let loose, makes its own decisions on what actions are and aren’t allowed. There is a suspicion that the smart contract involved had this line in it: require(_share_price > 0, "Invalid share price"); when it should have been require(_share_price >= 0, "Invalid share price"); and, depending on rounding errors, this could have caused all attempts at redemption to fail if the price fell too low to be distinguished from zero. And unlike regular legal contracts between carbon-based life forms, no court can overrule the operation of a smart contract†. Once it is put into effect, there is no reining it in. If the code is bug-free, you are fine (Do I hear sardonic laughter?). How many dozens of sci-fi stories and movies (both good and bad) have gone over this basic scenario? Do people learn nothing from pulp fiction!? But then again, the company did say "We already queued the fix for this, so people can redeem again at 5pm UTC." so maybe this wasn’t the issue at all. †Probably. None has yet tried.

Newly discovered Vigilante malware outs software pirates and blocks them

Vigilante, as SophosLabs Principal Researcher Andrew Brandt is calling the malware, gets installed when victims download and execute what they think is pirated software or games. Behind the scenes, the malware reports the file name that was executed to an attacker-controlled server, along with the IP address of the victims’ computers.

Google Backs Linux Project To Make Android, Chrome OS Harder To Hack
by Peter Reutemann 18 Jun '21

18 Jun '21

'Google said Thursday it's funding a project to increase Linux security by writing parts of the operating system's core in the Rust programming language, a modernization effort that could bolster the security of the internet and smartphones. From a report: If the project succeeds, it'll be possible to add new elements written in Rust into the heart of Linux, called the kernel. Such a change would mark a major technological and cultural shift for an open-source software project that's become foundational to Google's Android and Chrome operating systems as well as vast swaths of the internet. Miguel Ojeda, who's written software used by the Large Hadron Collider particle accelerator and worked on programming language security, is being contracted to write software in Rust for the Linux kernel. Google is paying for the contract, which is being extended through the Internet Security Research Group, a nonprofit that's also made it easier to secure website communications through the Let's Encrypt effort. Adding Rust modules to the Linux kernel would improve security by closing some avenues for hackers can use to attack phones, computers or servers. Since it was launched in 1991, Linux has been written solely in the powerful but old C programming language. The language was developed in 1972 and is more vulnerable to hacks than contemporary programming languages.' -- source: https://linux.slashdot.org/story/21/06/17/185239 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Report Finds Phone Network Encryption Was Deliberately Weakened
by Peter Reutemann 18 Jun '21

18 Jun '21

'A weakness in the algorithm used to encrypt cellphone data in the 1990s and 2000s allowed hackers to spy on some internet traffic, according to a new research paper. Motherboard: The paper has sent shockwaves through the encryption community because of what it implies: The researchers believe that the mathematical probability of the weakness being introduced on accident is extremely low. Thus, they speculate that a weakness was intentionally put into the algorithm. After the paper was published, the group that designed the algorithm confirmed this was the case. Researchers from several universities in Europe found that the encryption algorithm GEA-1, which was used in cellphones when the industry adopted GPRS standards in 2G networks, was intentionally designed to include a weakness that at least one cryptography expert sees as a backdoor. The researchers said they obtained two encryption algorithms, GEA-1 and GEA-2, which are proprietary and thus not public, "from a source." They then analyzed them and realized they were vulnerable to attacks that allowed for decryption of all traffic. When trying to reverse-engineer the algorithm, the researchers wrote that (to simplify), they tried to design a similar encryption algorithm using a random number generator often used in cryptography and never came close to creating an encryption scheme as weak as the one actually used: "In a million tries we never even got close to such a weak instance," they wrote. "This implies that the weakness in GEA-1 is unlikely to occur by chance, indicating that the security level of 40 bits is due to export regulations." Researchers dubbed the attack "divide-and-conquer," and said it was "rather straightforward." In short, the attack allows someone who can intercept cellphone data traffic to recover the key used to encrypt the data and then decrypt all traffic. The weakness in GEA-1, the oldest algorithm developed in 1998, is that it provides only 40-bit security. That's what allows an attacker to get the key and decrypt all traffic, according to the researchers.' -- source: https://it.slashdot.org/story/21/06/17/206213 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

14 Jun '21

'In a blog post on Thursday, GitHub security researcher Kevin Backhouse announced that Polkit, a Linux system service included in several modern Linux distros that provides an organized way for non-privileged processes to communicate with privileged ones, has been harbouring a major security bug for seven years. The bug, assigned (CVE-2021-3560) allows a non-privileged user to gain administrative shell access with a handful of standard command line tools. The bug was fixed on June 3, 2021 in a coordinated disclosure. "It's used by systemd," GitHub's blog post points out, "so any Linux distribution that uses systemd also uses polkit..." "It's very simple and quick to exploit, so it's important that you update your Linux installations as soon as possible. Any system that has polkit version 0.113 (or later) installed is vulnerable. That includes popular distributions such as RHEL 8 and Ubuntu 20.04."' -- source: https://linux.slashdot.org/story/21/06/12/174231 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linus Torvalds Tells Anti-Vaxxer To Shut Up On Linux Mailing List
by Peter Reutemann 14 Jun '21

14 Jun '21

'Linus Torvalds was "clearly unamused" by a "humanoid conspiracy theory, and also on its discussion in a Linux kernel topic thread," reports Neowin. They add that Torvalds "weighed in quite heavily with some very strong language, mixed with some biology lessons..." Here's an excerpt from Torvalds' response (as shared by Slashdot reader Hmmmmmm): Please keep your insane and technically incorrect anti-vax comments to yourself. You don't know what you are talking about, you don't know what mRNA is, and you're spreading idiotic lies. Maybe you do so unwittingly, because of bad education. Maybe you do so because you've talked to "experts" or watched youtube videos by charlatans that don't know what they are talking about. But dammit, regardless of where you have gotten your mis-information from, any Linux kernel discussion list isn't going to have your idiotic drivel pass uncontested from me. Vaccines have saved the lives of literally tens of millions of people. Just for your edification in case you are actually willing to be educated: mRNA doesn't change your genetic sequence in any way. It is the exact same intermediate - and temporary - kind of material that your cells generate internally all the time as part of your normal cell processes, and all that the mRNA vaccines do is to add a dose their own specialized sequence that then makes your normal cell machinery generate that spike protein so that your body learns how to recognize it. The half-life of mRNA is a few hours. Any injected mRNA will be all gone from your body in a day or two. It doesn't change anything long-term, except for that natural "your body now knows how to recognize and fight off a new foreign protein" (which then tends to fade over time too, but lasts a lot longer than a few days). And yes, while your body learns to fight off that foreign material, you may feel like shit for a while. That's normal, and it's your natural response to your cells spending resources on learning how to deal with the new threat. And of the vaccines, the mRNA ones are the most modern, and the most targeted - exactly because they do *not* need to have any of the other genetic material that you traditionally have in a vaccine (ie no need for basically the whole - if weakened - bacterial or virus genetic material). So the mRNA vaccines actually have *less* of that foreign material in them than traditional vaccines do. And a *lot* less than the very real and actual COVID-19 virus that is spreading in your neighborhood. Honestly, anybody who has told you differently, and who has told you that it changes your genetic material, is simply uneducated. You need to stop believing the anti-vax lies, and you need to start protecting your family and the people around you. Get vaccinated... Get vaccinated. Stop believing the anti-vax lies. And if you insist on believing in the crazy conspiracy theories, at least SHUT THE HELL UP about it on Linux kernel discussion lists.

Also Leaving Freenode: FSF, GNU, plus Linux and Python support channels
by Peter Reutemann 14 Jun '21

14 Jun '21

'Freenode's Linux support channel has an official web page at freenode.linux.community, which now bears this announcement: 22+ year old ##linux on freenode has been seized by freenode staff The community's (multi-platform) site reminds visitors of the alternative channels #linux on Libera and Linux.Chat on Discord. But they're not the only ones making changes. "[T]he FSF and GNU have decided to relocate our IRC channels to Libera.Chat," reads an official announcement on the FSF blog. "Effective immediately, Libera is the official home of our channels, which include but are not limited to all those in the #fsf, #gnu, and #libreplanet namespaces." As we have had nearly twenty years of positive experiences with the Freenode staff, most of whom now comprise the staff of the Libera network, we are confident in their technical and interpersonal expertise, as well as their ability to make the network as long-lasting and integral to the free software community as they made Freenode. We look forward to joining the large number of free software and free culture projects who have already made Libera.Chat their home, and hope to stay there for many years to come. Also making a move: freenode's #Python channel. Software developer Ned Batchelder, one of the channel's operators (and also an architect at edX), shared a recent experience in a new blog post this morning. When they'd decided to move #python to the new Libera.chat network (run by former Freenode staffers), they also stayed in Freenode's channel "to let people know where everyone had gone." Yesterday, after a heated debate in the Freenode channel where I was accused of splitting the community, I got k-lined (banned entirely from Freenode). The reason given was "spamming", because of my recurring message about the move to Libera. Then the entire Freenode #python channel was closed... Was it malice or was it mistake? Does it matter? It's not a good way to run a network. After the channel was closed, people asking staff about what happened were banned from asking. That wasn't a mistake... [T]he new staff seems to be using force to silence people asking questions. It's clear that transparency is not a strong value for them. Setting aside network drama, the big picture here is that the Freenode #python community isn't split: it's alive and well. It's just not on Freenode anymore, it's on Libera. Freenode was a good thing. But the domain name of the server was the least important part of it, just a piece of technical trivia. There's no reason to stick with Freenode just because it is called Freenode. As with any way of bringing people together, the important part is the people. If all of the people go someplace else, follow them there, and continue. See you on Libera.' -- source: https://tech.slashdot.org/story/21/06/13/184251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Vivaldi Browser Now Has Mail, Calendar, and An RSS Reader Built-In
by Peter Reutemann 10 Jun '21

10 Jun '21

'The Vivaldi 4.0 release is launching today, and includes a built-in email, calendar, and RSS reader. The Verge reports: The email client supports IMAP and POP accounts, so you can connect the vast majority of email services to it, and you can easily have messages open up in tabs rather than taking over the current window -- handy if you're the type who often needs to bounce between emails. The search is also, in my experience, very quick. The calendar and RSS reader also include most of the features I'd expect, along with a few really cool bonuses. For example, the RSS reader also supports YouTube channels, which could be handy for those who are worried about an algorithm deciding not to show a creator's videos. The other headline feature of this Vivaldi update is built-in translation. The browser will be able to translate entire webpages (automatically, if you want) in 50 languages as of today, but the company says it'll be expanding to support 109 languages soon. While the Mail tools are desktop only, the translation is also available on Vivaldi for Android. Vivaldi has also come up with a solution for those who don't want these features taking up room in their browser: you'll be able to choose between three layouts, which will give you a basic web browser, one with a few power-user features, or the all-in-one experience with email, calendars, and RSS. All the features will still be available, even in the "Essentials" layout, but they won't be taking up space in the interface.

Linux X86/x86_64 Will Now Always Reserve the First 1MB of RAM
by Peter Reutemann 10 Jun '21

10 Jun '21

'Phoronix reports: The Linux x86/x86_64 kernel code already had logic in place for reserving portions of the first 1MB of RAM to avoid the BIOS or kernel potentially clobbering that space among other reasons while now Linux 5.13 is doing away with that 'wankery' and will just unconditionally always reserve the first 1MB of RAM. The Linux kernel was already catering to Intel Sandy Bridge graphics accessing memory below the 1MB mark, the first 64K of memory are known to be corrupted by some BIOSes, and similar problems coming up in that low area of memory. But rather than dealing with all that logic and other possible niche cases besides the EGA/VGA frame-buffer and BIOS, the kernel is playing it safe and just always reserving the first 1MB of RAM so it will not get clobbered by the kernel.' -- source: https://linux.slashdot.org/story/21/06/09/2122210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Space: (Not) The Final Frontier ...
by Lawrence D'Oliveiro 09 Jun '21

09 Jun '21

You may know that a cryptocurrency like Bitcoin gets its value from a concept known as “proof of work” -- namely that in order to “mine” (create new units of) the currency, you performed a computation with a commonly-accepted minimum complexity (with no known shortcuts). Now there is another kind of cryptocurrency, based on “proof of space”, where the (agreed) value comes from permanently setting aside some amount of storage space. Instead of consuming some increasing percentage of the world’s electricity (and GPU) supply, this one is going to consume some increasing percentage of the world’s hard drive supply. <https://www.theregister.com/2021/06/08/chia_cryptocurrency_creates_euro_hdd…>

KDE Plasma 5.22 Released
by Peter Reutemann 09 Jun '21

09 Jun '21

'KDE Plasma 5.22 is now available, bringing "hugely improved" Wayland support, better performance for gaming, adaptive panel transparency for the panel and widgets, and more. Phoronix reports: There is now support for variable rate refresh (VRR) / Adaptive-Sync on Wayland, vertical/horizontal maximization now working with KWin Wayland, global menu applet support under Wayland, support for activities, and a lot of other general improvements and fixes so the overall Wayland support is much more polished and nearly at par to the X.Org Server support. The performance for gaming with KDE Plasma on Wayland should also be better with now having direct scan-out support for full-screen windows. Rounding out the graphics fun with this release is also GPU hot-plugging support on Wayland for KWin, such as if using an external GPU or USB display adapter. KDE Plasma 5.22 also delivers on adaptive panel transparency for the panel and widgets, desktop notification improvements, Plasma System Monitor has replaced KSysGuard as the default system monitoring application, and a variety of other improvements. You can view the full changelog for Plasma 5.22 here.' -- source: https://tech.slashdot.org/story/21/06/08/1938202 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

ESA’s Mars Express Orbiter Is 18 Years Old
by Lawrence D'Oliveiro 04 Jun '21

04 Jun '21

<https://www.theregister.com/2021/06/02/mars_express/> In some industries, you really have to take the long view about your computing infrastructure: Wood recently shared a Twitter thread that began, much to the delight of retro-computing fans, with the recovery of data from two IDE drives from a long-dead PC and (spoiler alert) ended with the 25-year-old emulator for the Star Tracker software firing up on a 486-based machine running Windows for Workgroups 3.11 (after more modern Microsoft operating systems rejected it.) ... Alternatively, hardware on Earth could give up the ghost. The mission control systems for Mars Express originally ran on Solaris 8 machines (and some tools ran on Solaris 6.) A migration to Solaris 10 occurred in 2013 although, with a hat-tip to the Unix team working around failing ancient hardware, Wood observed: "We have Solaris 10, running a Solaris 8 zone and that zone is configured in Solaris 6 compatibility mode. (it really is turtles all the way down!)" Virtualization efforts have played their part in reducing the reliance on hard-to-obtain components. Should ESA keep the funding tap turned on and extend the mission past the end of 2022, an upgrade to Solaris 11 servers is also on the cards (a joint activity with other ESA missions XMM and Integral) that should last until the end of Mars Express.

How Facebook Architects Around Silent Data Corruption
by Lawrence D'Oliveiro 04 Jun '21

04 Jun '21

Seems like Facebook’s computation facilities have become so massive that it is starting to see intermittent errors in places you wouldn’t expect <https://www.nextplatform.com/2021/03/01/facebook-architects-around-silent-d…>: Engineers found that many of the cascading errors are the result of CPUs in production but not always due to the “soft errors” of radiation or synthetic fault injection. Rather, they find these can happen randomly on CPUs in repeatable ways. Although ECC is useful, this is focused on problems in SRAM but other elements are susceptible. The Facebook engineering team that reported on these problems finds that CPU silent data corruptions are actually orders of magnitude higher than soft-errors due to a lack of error correction in other blocks. The article mentions examples like a computation of 2×3 sometimes returning an answer other than 6, or a file size intermittently (and incorrectly) being computed as zero, leading to the file data not being copied. Such occurrences may be extremely rare, but when you are doing things on the scale that Facebook does, they start to become all too common. Facebook has published a paper (linked in the report) on their research into the problem. They have worked out some techniques to try to mitigate these issues, but of course they come at a cost.

The Collective Code Construction Contract
by Lawrence D'Oliveiro 04 Jun '21

04 Jun '21

Came across this interesting document <https://rfc.zeromq.org/spec/42/> referenced from another project I was browsing. It is a set of guidelines for how Free Software projects should be managed. Some choice extracts: The project SHALL use the git distributed revision control system. The project SHALL use a share-alike license such as the MPLv2, or a GPLv3 variant thereof (GPL, LGPL, AGPL). All contributions to the project source code (“patches”) SHALL use the same license as the project. All patches are owned by their authors. There SHALL NOT be any copyright assignment process. Some specifics of how to use, and not to use, Git: The project SHALL have one branch (“master”) that always holds the latest in-progress version and SHOULD always build. The project SHALL NOT use topic branches for any reason. Personal forks MAY use topic branches. To make a stable release a Maintainer shall tag the repository. Stable releases SHALL always be released from the repository master. Actually that last one seems a bit questionable. For example, Blender does not structure its repos that way. Each stable release has its own branch, which may continue to accumulate bug fixes for as long as it is under support, while main development of the next version continues on the master branch. Plus there guidelines for handling people-management issues, of course: Administrators SHOULD block or ban “bad actors” who cause stress and pain to others in the project. This should be done after public discussion, with a chance for all parties to speak. A bad actor is someone who repeatedly ignores the rules and culture of the project, who is needlessly argumentative or hostile, or who is offensive, and who is unable to self-correct their behavior when asked to do so by others.

Google is Making it Harder for Android Apps To Track You Once You've Opted Out
by Peter Reutemann 04 Jun '21

04 Jun '21

'It's going to get harder for Android apps to track users who've opted out of receiving personalized ads, the Financial Times reports, after Google announced changes to how it'll handle the unique device identifiers that allow marketers to track them between apps. From a report: Starting later this year, Google is cutting off access to these "Advertising IDs" after a user opts out, and will show developers a "string of zeros" in its place. The news was announced in an email to Play Store developers, and Google has also updated its support page for Advertising IDs with the announcement. Google told developers the changes will "provide users with more control over their data, and help bolster security and privacy," the Financial Times reports. The change comes a few short months after Apple overhauled how advertising IDs work on iOS in an apparent attempt to compete with the new policy.

Microsoft’s Package Manager Quality Issue
by Lawrence D'Oliveiro 03 Jun '21

03 Jun '21

Microsoft has officially launched “Winget”, aka the Windows Package Manager <https://www.theregister.com/2021/06/02/microsoft_introduces_moderation_for_…>. Unfortunately, it’s run into a bit of a snag: anybody can submit packages to be included in the repo willy-nilly, leading to problems like duplicates, bad links and other misbehaviour. “What is wrong with this picture?” as they say: Look at any of the common Linux distros, and you will see that every package has an official maintainer who will take responsibility for its quality, handling of bug reports, updating from upstream and so on. Nobody can simply submit a package to be included and then forget about it. There is a proper QA system.

No More CLA For GCC
by Lawrence D'Oliveiro 03 Jun '21

03 Jun '21

The Free Software Foundation has long been one of those outfits that has refused to accept (significant) source contributions without the author signing a “Contributor Licence Agreement”. It’s not enough to release the code under the same licence as the project, you must also hand over the entire copyright to them. This is supposedly because they have received legal advice that it makes it easier to defend against copyright infringements if they own all the code. Quite a few other projects don’t agree <https://lwn.net/Articles/592503/>. For example, the Linux kernel project does not demand CLAs, only a “Certificate of Origin” (affirming that you have the right to contribute the code). And now the GNU Compiler Collection is joining them. <https://www.theregister.com/2021/06/02/gcc_fsf_code_copyright/>

Alibaba's Huge Browser Business Is Harvesting The 'Private' Web Activity Of Millions Of Android And iPhone Users
by Peter Reutemann 03 Jun '21

03 Jun '21

'Security researcher Gabi Cirlig's findings, verified for Forbes by two other independent researchers, reveal that on both Android and iOS versions of UC Browser, every website a user visits, regardless of whether they're in incognito mode or not, is sent to servers owned by UCWeb. From a report: Cirlig said IP addresses -- which could be used to get a user's rough location down to the town or neighborhood of the user -- were also being sent to Alibaba-controlled servers. Those servers were registered in China and carried the .cn Chinese domain name extension, but were hosted in the U.S. An ID number is also assigned to each user, meaning their activity across different websites could effectively be monitored by the Chinese company, though it's not currently clear just what Alibaba and its subsidiary are doing with the data. "This could easily fingerprint users and tie them back to their real personas," Cirlig wrote in a blog post handed to Forbes ahead of publication on Tuesday. Cirlig was able to uncover the problem by reverse engineering some encrypted data he spotted being sent back to Beijing. Once the key had been cracked, he was able to see that every time he visited a website, it was being encrypted and transmitted back to the Alibaba company. On Apple's iOS, he didn't even need to reverse engineer the encryption because there effectively was none on the device (though it was encrypted when in transit). "This kind of tracking is done on purpose without any regard for user privacy," Cirlig told Forbes. When compared to Google's own Chrome browser, for instance, it does not transfer user web browsing habits when in incognito. Cirlig said he'd looked at other major browsers and found none did the same as UC Browser.
