by Peter Reutemann 24 May '22

24 May '22

'This weekend, Miguel Ojeda, added support for a set of additional Rust patches in the kernel and separately a new version of Uutils which is the Rust version of GNU CoreUtils. These changes will go towards more inclusion of Rust into Linux. The v7 patches adds in abstractions used by Rust and the Uutils update contained fixes and addresses compatibility issues.' -- source: https://linux.slashdot.org/story/22/05/23/1836210 Anybody keen on demoing this Rust support or how to write a kernel module in general?

Microsoft's Windows Subsystem For Android Just Got a Big Update
by Peter Reutemann 24 May '22

24 May '22

'Microsoft has updated the Windows Subsystem for Android (WSA) to Android 12.1 and shipped improvements to Android integration with Windows, networking, the camera in apps, the Settings app, and more. ZDNet reports: Current limitations aside, Microsoft is continuing to invest in bringing Android to Windows 11, as seen in its update to the WSA on Windows 11 (version 2204.40000.15) to Android 12.1, which is available to Insiders on the Dev Channel, according to a Microsoft blogpost. WSA launched with Android 11. Microsoft has improved networking on the Windows Subsystem for Android, so that Android apps can connect to devices on the same network as a Windows PC. Advanced networking allows users to set up smart home devices such as speakers and security cameras with a compatible Android app. This feature is available in Windows 11 preview builds 22621 and higher, with advanced networking on by default for new x64 Windows builds. Android-Windows integration has also been improved. Windows taskbar icons now show which Android apps are currently using hardware features like the mic and location in the system tray. The taskbar now also correctly appears or disappears when apps are running or stopped. Android notifications also show as Windows notifications and the Windows title of an Android app now reflects the Android activity title. Android apps won't restart afresh after exiting connected standby mode, but instead will recommence where the app was paused. Of the "many camera updates" in this release, Microsoft highlights that camera orientation is fixed to natural orientation, and that it's fixed incorrect camera previews, letterboxing (where the app window is wider than it is high, or horizontally longer), and a "squishing of the camera feed." Mouse and keyboard inputs in Windows Subsystem for Android have been improved. Microsoft also improved scroll-wheel support, fixed the onscreen keyboard focus, and ensured the Android soft keyboard displays correctly. The updated Windows Subsystem for Android Settings app gained redesigned UX and diagnostics data viewer. As of this update, telemetry collection is off by default. However, Microsoft is encouraging users to enable the setting, so it can collect data about Android app usage. "Other important updates include reduced flicker when apps are restored from a minimized state, the addition of VP8 and VP9 video hardware decoding, and the addition of Chromium WebView 100 to the Windows Subsystem for Android," adds ZDNet.' -- source: https://tech.slashdot.org/story/22/05/23/2014243 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Researchers find backdoor lurking in WordPress plugin used by schools
by Peter Reutemann 23 May '22

23 May '22

'Researchers said on Friday that they found a malicious backdoor in a WordPress plugin that gave attackers full control of websites that used the package, which is marketed to schools. The premium version of School Management, a plugin schools use to operate and manage their websites, has contained the backdoor since at least version 8.9, researchers at website security service Jetpack said in a blog post without ruling out that it had been present in earlier versions. This page from a third-party site shows that version 8.9 was released last August.' -- source: https://arstechnica.com/information-technology/2022/05/researchers-find-bac… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Why Gov.UK Stopped Using jQuery
by Peter Reutemann 22 May '22

22 May '22

'The head of the UK government's digital transformation unit recently announced a change to the nation's government services site gov.uk: they've "removed jQuery as a dependency for all frontend apps, meaning 32 KB of minified and compressed JavaScript was removed" for everything from selecting elements to attaching event listeners.... Nearly 84% of mobile pages used jQuery in 2021, points out a new essay at Gov.UK — before explaining why they decided not to: jQuery was an instrumental tool in a time when we really needed a way to script interactivity in a way that smoothed over the differing implementations of stuff like event handling, selecting elements, animating elements, and so on. The web is better because of jQuery — not just because it has such incredible utility, but because its ubiquity led to making what it provided part of the web platform itself. Nowadays, we can do just about anything jQuery can do in vanilla JavaScript... It really begs the question: Do we really need jQuery today? That's a question that GOV.UK has answered with a resounding "no".... This is a big deal when it comes to the user experience, because GOV.UK provides services and information online for The United Kingdom at scale. Not everyone is tapping away on their 2022 MacBook Pro on a rip-roarin' broadband connection. GOV.UK has to be accessible to everyone, and that means keepin' it lean.... dependencies matter when it comes to performance. Don't shortchange your users if the web platform can easily do the job a framework can. This level of commitment to the user experience from a institution that works at the scale GOV.UK does is commendable. I can only hope others follow in their footsteps.' -- source: https://developers.slashdot.org/story/22/05/21/0214233 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

HP Chooses Ubuntu-Based Pop!_OS Linux For Its Upcoming Dev One Laptop
by Peter Reutemann 22 May '22

22 May '22

'System76's CEO Carl Richell announced that HP has chosen the Ubuntu-based Pop!_OS operating system to run on its 14-inch developer-focused notebook called "Dev One." Brian Fagioli from BetaNews speculates that a HP acquisition of System76 "could be a possibility in the future -- if this new relationship pans out at least." He continues: HP could be testing the waters with the upcoming Dev One. Keep in mind, System76 does not even build its own laptops, so we could see the company leave the notebook business and focus on desktops only -- let HP handle the Pop!_OS laptops. "We've got you covered. Experience exceptional multi-core performance from the AMD Ryzen 7 PRO processor and multitask with ease. Compile code, run a build, and keep all your apps running with more speed from the 16GB memory. Plus, load and save files in a flash, thanks to 1TB fast PCIe NVMe M.2 storage. We've even added a Linux Super key so shortcuts are a click away. Simply put, HP Dev One is built to help you code better," explains HP. The company adds, "Pop!_OS is at your service. Create your ideal work experience with multiple tools to help you perform with peak efficiency. Use Stacking to organize and access multiple applications, browsers, and terminal windows. Move, resize, and arrange windows with ease or, let Pop!_OS keep you organized and efficient with Auto-tiling. And use Workspaces to reduce clutter by organizing windows across multiple desktops." Apparently, there will only be one configuration priced at $1,099. So far, no details about a release date have been announced other than "coming soon."' -- source: https://news.slashdot.org/story/22/05/21/0228258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How a Rust Supply-Chain Attack Infected Cloud CI Pipelines with Go Malware
by Peter Reutemann 22 May '22

22 May '22

'Sentinel Labs provides malware/threat intelligence analysis for the enterprise cybersecurity platform SentinelOne. Thursday they reported on "a supply-chain attack against the Rust development community that we refer to as 'CrateDepression'." On May 10th, 2022, the Rust Security Response Working Group released an advisory announcing the discovery of a malicious crate hosted on the Rust dependency community repository. The malicious dependency checks for environment variables that suggest a singular interest in GitLab Continuous Integration (CI) pipelines. Infected CI pipelines are served a second-stage payload. We have identified these payloads as Go binaries built on the red-teaming framework, Mythic. Given the nature of the victims targeted, this attack would serve as an enabler for subsequent supply-chain attacks at a larger-scale relative to the development pipelines infected. We suspect that the campaign includes the impersonation of a known Rust developer to poison the well with source code that relies on the typosquatted malicious dependency and sets off the infection chain.... In an attempt to fool rust developers, the malicious crate typosquats against the well known rust_decimal package used for fractional financial calculations.... The malicious package was initially spotted by an avid observer and reported to the legitimate rust_decimal github account.... Both [Linux and macOs] variants serve as an all-purpose backdoor, rife with functionality for an attacker to hijack an infected host, persist, log keystrokes, inject further stages, screencapture, or simply remotely administer in a variety of ways.... Software supply-chain attacks have gone from a rare occurrence to a highly desirable approach for attackers to 'fish with dynamite' in an attempt to infect entire user populations at once. In the case of CrateDepression, the targeting interest in cloud software build environments suggests that the attackers could attempt to leverage these infections for larger scale supply-chain attacks.' -- source: https://developers.slashdot.org/story/22/05/21/0520207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Modular, DIY-friendly Framework Laptop gets updated with 12th-gen Intel CPUs
by Peter Reutemann 20 May '22

20 May '22

'We were fans of the Framework Laptop when we reviewed it last year. This was partly because its modular design prioritizes repairability and upgradeability when most other laptops don't. But we also liked it because you didn't need to make huge tradeoffs to get that repairability—the Framework Laptop is lightweight and has a high-quality screen, keyboard, and touchpad, helping it stay competitive with big-box thin-and-light laptops like Dell's XPS 13 and the Lenovo ThinkPad X1 Carbon. An upgradeable laptop is only worthwhile if you can actually upgrade it, though, and Framework is making that possible starting today: The company is introducing a new iteration of the Framework Laptop's motherboard that uses 12th-gen Intel CPUs. A brand-new 12th-gen Framework Laptop starts at $1,049 for a Core i5-equipped base model, or $819 for a build-it-yourself kit with no memory or storage. These products will be available for preorder starting today, and shipping will start in July. [...] While many of Framework's PCs will run Windows, the company boasts that the 12th-gen version of its laptop "continue[s] to focus on solid Linux support." Framework recommends Fedora 36 because it "works fantastically well out of the box" and fully supports the Framework Laptop's new CPUs, its Wi-Fi card, and its fingerprint reader. For now, though, you'll need to be careful about installing other Linux distributions—you need Linux kernel version 5.17.6 or newer to fully support Alder Lake's hybrid CPU architecture, and prominent, actively maintained distributions like Ubuntu 22.04 don't include that kernel version out of the box. This problem will disappear for most Linux distros within the next few months, but for now you may need to upgrade the kernel manually to get the best-possible Linux experience on the Framework Laptop. -- source: https://arstechnica.com/gadgets/2022/05/modular-diy-friendly-framework-lapt… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New Bluetooth hack can unlock your Tesla—and all kinds of other devices
by Peter Reutemann 19 May '22

19 May '22

'When you use your phone to unlock a Tesla, the device and the car use Bluetooth signals to measure their proximity to each other. Move close to the car with the phone in hand, and the door automatically unlocks. Move away, and it locks. This proximity authentication works on the assumption that the key stored on the phone can only be transmitted when the locked device is within Bluetooth range. Now, a researcher has devised a hack that allows him to unlock millions of Teslas—and countless other devices—even when the authenticating phone or key fob is hundreds of yards or miles away. The hack, which exploits weaknesses in the Bluetooth Low Energy standard adhered to by thousands of device makers, can be used to unlock doors, open and operate vehicles, and gain unauthorized access to a host of laptops and other security-sensitive devices.' -- source: https://arstechnica.com/information-technology/2022/05/new-bluetooth-hack-c… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Blocks File Manager Total Commander From Allowing Users To Sideload Apps
by Peter Reutemann 19 May '22

19 May '22

'Total Commander has been around since the 90s, eventually expanding into Android after the platform launched over a decade ago. The app has more than 10 million downloads on the Play Store, still supporting OS versions as far back as Android 2.2. With a new update, developer Christian Ghisler has removed the ability to install APK files on Android, blaming Google Play policies in the patch notes for the app. It's a shocking twist for the service and, seemingly, a bad omen of things to come for other mobile file managers. A forum post from Ghisler sheds some more light on what's going on here, as Google sent him a notice warning of his app's removal from the Play Store within a week if the app went unmodified. The company's automated response pointed the developer to the "Device and Network Abuse" policy.' -- source: https://tech.slashdot.org/story/22/05/18/1843221 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Will Start Distributing a Security-Vetted Collection of Open-Source Software Libraries
by Peter Reutemann 18 May '22

18 May '22

'Google announced a new initiative Tuesday aimed at securing the open-source software supply chain by curating and distributing a security-vetted collection of open-source packages to Google Cloud customers. From a report: The new service, branded Assured Open Source Software, was introduced in a blog post from the company. In the post, Andy Chang, group product manager for security and privacy at Google Cloud, pointed to some of the challenges of securing open-source software and stressed Google's commitment to open source. "There has been an increasing awareness in the developer community, enterprises, and governments of software supply chain risks," Chang wrote, citing last year's major log4j vulnerability as an example. "Google continues to be one of the largest maintainers, contributors, and users of open source and is deeply involved in helping make the open source software ecosystem more secure." Per Google's announcement, the Assured Open Source Software service will extend the benefits of Google's own extensive software auditing experience to Cloud customers. All open-source packages made available through the service are also used internally by Google, the company said, and are regularly scanned and analyzed for vulnerabilities.' -- source: https://tech.slashdot.org/story/22/05/17/1726201 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
