Linksys Asks Users To Reset Passwords After Hackers Hijacked Home Routers Last Month
by Peter Reutemann 17 Apr '20

17 Apr '20

'Router vendor Linksys has locked user accounts on its Smart WiFi cloud service and is asking them to reset passwords after hackers have been observed hijacking accounts and changing router settings to redirect users to malware sites. From a report: Linksys' decision only impacts Smart WiFi accounts. Linksys Smart WiFi is a cloud-based account system that lets device owners connect to Linksys routers (and other equipment) over the internet to manage router settings. Smart WiFi is widely deployed across Linksys' router fleet, making it an ideal target for hackers who may want to hijack routers en-masse. According to a Bitdefender report published last month, this is exactly what's been recently happening. The cyber-security firm said it detected an organized campaign to break into D-Link and Linksys routers and change DNS settings.' -- source: https://it.slashdot.org/story/20/04/16/1727210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The secret behind “unkillable” Android backdoor called xHelper has been revealed
by Peter Reutemann 17 Apr '20

17 Apr '20

'In February, a researcher detailed a widely circulating Android backdoor that’s so pernicious that it survives factory resets, a trait that makes the malware impossible to remove without taking unusual measures. The analysis found that the unusual persistence was the result of rogue folders containing a trojan installer, neither of which was removed by a reset. The trojan dropper would then reinstall the backdoor in the event of a reset. Despite those insights, the researcher still didn’t know precisely how that happened. Now, a different researcher has filled in the missing pieces.' -- source: https://arstechnica.com/information-technology/2020/04/solved-how-android-b… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox To Remove Support For the FTP Protocol
by Peter Reutemann 16 Apr '20

16 Apr '20

'Mozilla has announced plans to remove support for the FTP protocol from Firefox. Going forward, users won't be able to download files via the FTP protocol and view the content of FTP links/folders inside the Firefox browser. From a report: "We're doing this for security reasons," said Michal Novotny, a software engineer at the Mozilla Corporation, the company behind the Firefox browser. "FTP is an insecure protocol and there are no reasons to prefer it over HTTPS for downloading resources," he said. "Also, a part of the FTP code is very old, unsafe and hard to maintain and we found a lot of security bugs in it in the past." Novotny says Mozilla plans to disable support for the FTP protocol with the release of Firefox 77, scheduled for release in June this year.' -- source: https://news.slashdot.org/story/20/03/19/169246 There's always FileZilla...

NASA Uses 3D Cardboard Glasses
by Lawrence D'Oliveiro 16 Apr '20

Here’s a fun one: normally, the drivers of the Curiosity Mars rover have active-shutter 3D glasses for viewing images of the Martian terrain on their office machines. But these don’t work on the hardware that these staffers are currently using from home.

A security researcher has been taking a look at a piece of “CPAP” (“Continuous Positive Airway Pressure”) equipment <https://arstechnica.com/information-technology/2020/04/firmware-jailbreak-l…>, normally used to treat sleep apnoea, just to see whether it can be adapted to function as a “BIPAP” (“Bi-Level Positive Airway Pressure”) device, i.e. a full-on ventilator. The manufacturer says no, but the researcher says yes, the device already has the essential functionality available in its firmware, just needing a patch to enable it.

A story with a happy ending
by Ian Stewart 15 Apr '20

15 Apr '20

Seven years ago, in March 2013, I discovered a bug in the BASIC programming language that is included with LibreOffice suite of applications. I found that if BASIC was requested to return a 1 to 4 x nibbles Hex string, it would return positive integers OK but it would have an error when attempting to return a negative integer. For examples: Cint(&H0) returned 0 OK Cint(&H7FFF) returned 32767 OK Cint(&HFFFF) should have returned -1, but returned an "overflow error" Cint(&H8000) should have returned -32768, but returned an "overflow error". On the 14th March 2013, I opened a case for this issue on Bugzilla and it was logged as Bug 62326 https://bugs.documentfoundation.org/show_bug.cgi?id=62326 === The most recent comment posted on this bug was two weeks ago: Comment 39 Commit Notification 2020-03-30 06:59:05 UTC Andreas Heinisch committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/core/commit/ffbcbbc8dcc946d4d91cc08a937c2067be5… Cleanup for tdf#130476, tdf#62323 and tdf#62326 It will be available in 7.0.0. === Version 7.0 of LibreOffice is scheduled for release in August 2020. === So.... Good things come to those who wait! cheers, Ian.

RIP John Conway
by Lawrence D'Oliveiro 15 Apr '20

One of the higher-profile victims† of Covid-19 has been mathematician John Conway, best known to most people for the invention of the cellular-automata game he called “Life”. This article <https://arstechnica.com/science/2020/04/john-conway-inventor-of-the-game-of…> has some details, including a link to a YouTube video showing a quite amazing configuration of 6 “engines” that generate an endless stream of “Corderships” that go sailing off in one direction. †Another victim I personally feel sad about is Tim Brooke-Taylor. But while I enjoyed his humour (for example in “The Goodies” and “At Last, The 1948 Show” on TV, and “I’m Sorry, I’ll Read That Again” on radio), I can’t think of anything appropriate to this group to say about him...

Samsung's S-Voice Is Shutting Down On June 1st
by Peter Reutemann 14 Apr '20

14 Apr '20

'Samsung is reportedly shutting off the servers for its S-Voice voice assistant on June 1, 2020, "at which point Samsung's original voice assistant will stop attempting to respond to your voice queries," reports Ars Technica. From the report: S-Voice arose in the early days of voice assistants, when Android OEMs were scrambling to photocopy Apple's Siri voice assistant, which launched in 2011. Samsung licensed the same underlying technology for S-Voice that Apple originally used for Siri -- Nuance Communication's voice recognition -- and set about building its Siri sibling. S-Voice was Samsung's chosen voice assistant for its smartphones until it rebooted its voice efforts with the launch of "Bixby" in 2017. Samsung's Bixby project initially grew out of an acquisition of Viv Labs, a voice-assistant company founded by members of the original Siri team (see a pattern here?). The Galaxy S8 and every device after it launched with Bixby and not S-Voice, so this shutdown should only effect older devices. SamMobile hunted down a list of applicable devices, saying "The affected models that have the S Voice icon on the app screen include the Galaxy A3, A5, A7, A8, A9, Galaxy Note FE, Galaxy Note 2, 3, 4, 5, Galaxy S3, 4, S5, S6, S6 edge in addition to the Galaxy Note Pro 12.2, Galaxy W, Galaxy Tab 4, Galaxy Tab 4 8.0/10.1, Galaxy Tab S8.4 and S10.5.

How Steak-umm Became The Tweeting Voice Of Reason In A Pandemic
by Lawrence D'Oliveiro 14 Apr '20

14 Apr '20

No, I had never heard of this US-based product before, either. But whoever is in charge of its Twitter account has decided to use their power for good, not for evil <https://www.techdirt.com/articles/20200410/17213944276/how-steak-umm-became…>. Consider comments like this: it can be difficult to know what to believe in a time when institutional trust is diminished and the gatekeepers of information have been dismantled, but it's more crucial now than ever before to follow a range of credentialed sources for both breaking news and data collection or this: you can maintain independent, critical thinking toward institutions without dipping into fringe conspiracies that get jumpstarted by individual anecdotes being virally spread as data. it's not easy, but it's necessary to keep any semblance of responsible online information flow or this: we're a frozen meat brand posting ads inevitably made to misdirect people and generate sales, so this is peak irony, but hey we live in a society so please make informed decisions to the best of your ability and don't let anecdotes dictate your worldview ok and this: people think it's bizarre, ironic, and funny when a frozen meat company points out the importance of critical thinking, but chances are the same message would never "go viral" if it was from a person. our society values entertainment over truth and that's a huge problem

Not actually Linux distro review deux: GhostBSD
by Peter Reutemann 14 Apr '20

14 Apr '20

'When I began work on the FreeBSD 12.1-RELEASE review last week, it didn't take long to figure out that the desktop portion wasn't going very smoothly. I think it's important for BSD-curious users to know of easier, gentler alternatives, so I did a little looking around and settled on GhostBSD for a follow-up review. GhostBSD is based on TrueOS, which itself derives from FreeBSD Stable. It was originally a Canadian distro, but—like most successful distributions—it has transcended its country of origin and can now be considered worldwide. Significant GhostBSD development takes place now in Canada, Italy, Germany, and the United States. The history of desktop-oriented BSD distros is a turbulent one. For several years, Kris Moore's PC-BSD was the go-to for "I want BSD, but I also want a ready-to-go desktop." Eventually, ixSystems—home of the FreeNAS storage distro, and the company Moore is vice president of engineering for—came to rely heavily on the server-side features developed into PC-BSD. The need at ixSystems for the foundation of PC-BSD without the associated desktop led to a rename and a fork. PC-BSD's underpinnings became TrueOS, and the desktop-friendly distribution—now based on TrueOS—became Project Trident. This state of affairs didn't last long. A year later, Project Trident declared unhappiness with TrueOS and BSD in general—mostly due to hardware support, or lack thereof. In January 2020, Trident rebased itself on Void Linux, which its developers found to be "the most BSD-like" of the potential Linux upstream distros they examined. Project Trident's departure for more Linux-y waters left several potential contenders for a desktop-focused BSD distribution. These include FuryBSD, MidnightBSD, DesktopBSD, and GhostBSD itself. I've tested PC-BSD fairly extensively in the past but have no history with any of the current desktop BSD choices. I chose GhostBSD for a first look, solely due to its prominence in Google search results for "desktop BSD distro."' -- source: https://arstechnica.com/gadgets/2020/04/not-actually-linux-distro-review-de… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux on Laptops: ASUS Zephyrus G14 with Ryzen 9 4900HS
by Peter Reutemann 14 Apr '20

'The Zephyrus G14 is a dual-GPU gaming laptop, and Linux tends not to fare well with that setup. But it's the only Ryzen 4000 equipped laptop I have available—so it was obviously going to get Linux on it, whether it liked it or not.

Coronavirus: Raspberry Pi-powered ventilator to be tested in Colombia
by Peter Reutemann 14 Apr '20

14 Apr '20

'A team in Colombia is to test a ventilator made with a Raspberry Pi computer and easy-to-source parts. The design and computer code were posted online in March by a man in California, who had no prior experience at creating medical equipment. Marco Mascorro, a robotics engineer, said he built the ventilator because knew the machines were in high demand to treat Covid-19. His post prompted a flood of feedback from healthcare workers. He has used the advice to make improvements. "I am a true believer that technology can solve a lot of the problems we have right now specifically in this pandemic," he told the BBC. The Colombian team said the design was important for their South American country because parts for traditional models could be hard to obtain. By contrast, Mr Mascorro's design uses only easy-to-find parts - for example, the valves it employs can commonly be found at car and plumbing supply stores. The machine is set to be put through a fast-tracked round of tests at two institutions in Bogota - the University Hospital of the Pontifical Xavierian University and Los Andes University.' -- source: https://www.bbc.com/news/technology-52251286 -- github: https://github.com/Mascobot/pandemic-ventilator-2.0 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Not-actually Linux distro review: FreeBSD 12.1-RELEASE
by Peter Reutemann 10 Apr '20

10 Apr '20

'This month's Linux distro review isn't of a Linux distribution at all—instead, we're taking a look at FreeBSD, the original gangster of free Unix-like operating systems. The first FreeBSD release was in 1993, but the operating system's roots go further back—considerably further back. FreeBSD started out in 1992 as a patch-release of Bill and Lynne Jolitz's 386BSD—but 386BSD itself came from the original Berkeley Software Distribution (BSD). BSD itself goes back to 1977—for reference, Linus Torvalds was only seven years old then. Before we get started, I'd like to acknowledge something up front—our distro reviews include the desktop experience, and that is very much not FreeBSD's strength. FreeBSD is far, far better suited to running as a headless server than as a desktop! We're going to get a full desktop running on it anyway, because according to Lee Hutchinson, I hate myself—and also because we can't imagine readers wouldn't care about it. FreeBSD does not provide a good desktop experience, to say the least. But if you're hankering for a BSD-based desktop, don't worry—we're already planning a followup review of GhostBSD, a desktop-focused BSD distribution.' -- source: https://arstechnica.com/gadgets/2020/04/not-actually-linux-distro-review-fr… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Signal Threatens To Dump US Market If EARN IT Act Passes
by Peter Reutemann 10 Apr '20

10 Apr '20

'Signal is warning that an anti-encryption bill circulating in Congress could force the private messaging app to pull out of the U.S. market. PC Magazine reports: Since the start of the coronavirus pandemic, the free app, which offers end-to-end encryption, has seen a surge in traffic. But on Wednesday, the nonprofit behind the app published a blog post, raising the alarm around the EARN IT Act. "At a time when more people than ever are benefiting from these (encryption) protections, the EARN IT bill proposed by the Senate Judiciary Committee threatens to put them at risk," Signal developer Joshua Lund wrote in the post. Although the goal of the legislation, which has bipartisan support, is to stamp out online child exploitation, it does so by letting the U..S government regulate how internet companies should combat the problem -- even if it means undermining the end-to-end encryption protecting your messages from snoops. If the companies fail to do so, they risk losing legal immunity under Section 230 of the Communications Decency Act, which can shield them from lawsuits concerning objectionable or illegal content posted on their websites or apps. "Some large tech behemoths could hypothetically shoulder the enormous financial burden of handling hundreds of new lawsuits if they suddenly became responsible for the random things their users say, but it would not be possible for a small nonprofit like Signal to continue to operate within the United States," Lund wrote in the blog post.' -- source: https://it.slashdot.org/story/20/04/09/2014207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Chinese Cybercriminals Target High-Value Linux Servers With Weak Defenses: BlackBerry
by Peter Reutemann 10 Apr '20

'Linux malware is real and Advanced Persistent Threat (APT) groups have been infiltrating critical servers with these tools for at least eight years, according to a new report from BlackBerry.

The RATs report describes how five APT groups are working with the Chinese government and the remote access trojans (RATs) the cybercriminals are using to get and maintain access to Linux servers. According to the report, the groups appeared to be using WINNTI-style tooling to take aim at Linux servers and remain relatively undetected for almost a decade. These groups are targeting Red Hat Enterprise, CentOS, and Ubuntu Linux environments for espionage and intellectual property theft. The APT groups examined include the original WINNTI GROUP, PASSCV, BRONZE UNION, CASPER (LEAD), and a newly identified group BlackBerry researchers are tracking as WLNXSPLINTER.

corp.com Saved From Falling Into The Wrong Hands
by Lawrence D'Oliveiro 09 Apr '20

09 Apr '20

Seems that early versions of Windows Active Directory would offer a default path name of “corp” during setup. Back in the days before the Internet became a part of everyday life, many admins accepted this without thinking too much about it. But once you start connecting servers to the Internet, they are liable to do DNS lookups on names like this, and accidentally connecting to something like “corp.com”. So to avoid such a name from coming under the control of less-than-savoury elements, Microsoft has bought it over <https://www.theregister.co.uk/2020/04/08/microsoft_active_directory/>. One of the reader comments links to this old Microsoft blog post <https://devblogs.microsoft.com/oldnewthing/20061013-05/?p=29393>, which explains that example/default names like “Contoso” and “Fabrikam” used in Microsoft’s documentation and products were actually created by their legal department, after a careful vetting process to ensure that they are indeed entirely fictitious.

Tails, the Security-Focused OS, Adds Support For Secure Boot
by Peter Reutemann 09 Apr '20

'Tail OS, an operating system optimized for privacy and anonymity, has released version 4.5 this week, the first version that supports a crucial security feature named UEFI Secure Boot. From a report: Secure Boot works by using cryptographic signatures to verify that firmware files loaded during a computer's boot-up process are authentic and have not been tampered. If any of the firmware checks fail, Secure Boot has the authority to stop the boot process, preventing the operating system from launching. The feature has been available as part of the UEFI specification for almost two decades but is rarely used. The reason is because not all firmware vendors cryptographically sign their files, leaving the door open to verification errors that -- when Secure Boot is enabled -- block many operation systems from launching.' -- source: https://it.slashdot.org/story/20/04/08/1712239 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google makes seamless update support mandatory in Android 11
by Peter Reutemann 09 Apr '20

09 Apr '20

'Google is putting new rules in place for Android 11: it's going to make support for Android's "seamless update" feature mandatory for devices launching with the new OS. The news comes to us via an Android source code commit first spotted by XDA Developers, which reads, "Require Virtual A/B on R launches." In English, this means the seamless update system, which requires two partitions (labeled "A" and "B"), will be required on Android R, aka Android 11. Android's seamless update system was introduced in Android 7.0 Nougat (it was actually borrowed from Chrome OS) as a way to reduce the downtime caused by OS updates and to offer a recovery mechanism in case an update applies incorrectly. Applying an update to an operating system usually means taking the OS offline for an extended period of downtime. On Android, before seamless updates, the phone would boot into recovery and could be stuck on the "Installing System Update" screen for as much as 25 minutes. That's a lot of downtime, and during this time you can't run any apps, see any text messages, or get any phone calls. The downtime happens because updating the system files requires taking the system partition offline, but the seamless update system fixes this by just having a second copy of the system partition.' -- source: https://arstechnica.com/gadgets/2020/04/google-makes-seamless-update-suppor… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox 75 Arrives With Revamped Address Bar; Mozilla To Stick With 2020 Schedule
by Peter Reutemann 08 Apr '20

08 Apr '20

'Mozilla today launched Firefox 75 for Windows, Mac, and Linux. Firefox 75 includes a revamped address bar with significant search improvements, a few performance tweaks, and a handful of developer features. You can download Firefox 75 for desktop now from Firefox.com, and all existing users should be able to upgrade to it automatically. According to Mozilla, Firefox has about 250 million active users, making it a major platform for web developers to consider. When the coronavirus crisis took hold, millions found themselves spending more time in their browsers as they learn and work from home. But the crisis is also impacting software developers. Google was forced to pause its Chrome releases, which typically arrive every six weeks. Ultimately, Chrome 81 was delayed, Chrome 82 is being skipped altogether, and Chrome 83 has been moved up a few weeks. Microsoft has followed suit with Edge's release schedule, consistent with Google's open source Chromium project, which both Chrome and Edge are based on. Mozilla wants to make clear it is not in the same boat. The company took an indirect jab at Google and Microsoft today, saying: "We've built empathy into our systems for handling difficult or unexpected circumstances. These strengths are what allow us to continue to make progress where some of our competitors have had to slow down or stop work."' -- source: https://news.slashdot.org/story/20/04/07/162246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Announces IPE, a New Code Integrity Feature for Linux
by Peter Reutemann 08 Apr '20

08 Apr '20

'Microsoft has revealed details about a new project it has been working on for Linux kernel. From a report: Named Integrity Policy Enforcement -- or IPE -- the project is a Linux security module (LSM). LSMs are optional add-ons for the Linux kernel that enable additional security features. According to a documentation page published on Monday, IPE is Microsoft's attempt to solve the code integrity problem for Linux -- an operating system the company broadly uses in its Azure cloud service. On Linux systems where IPE is enabled, system administrators can create a list of binaries that are allowed to execute and then add the verification attributes the kernel needs to check for each binary before allowing it to run. If binaries have been altered by an attacker, IPE can block the execution of the malicious code.' -- source: https://linux.slashdot.org/story/20/04/07/1615232 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Backs Apple's SMS OTP Standard Proposal
by Peter Reutemann 08 Apr '20

'Google is now backing a standard proposed by Apple engineers in January to create a default format for one-time passcodes (OTP) sent via SMS to users during the two-factor authentication (2FA) process. >From a report: The standard, proposed by Apple engineers working on the Safari WebKit project, has now reached the status of official Web Platform Incubator Community Group (WICG) specification draft. "We've moved 'Origin-bound one-time codes delivered via SMS' to @wicg_, where we're working on a shared spec with our collaborators at Google. Please take a look!

Edge Overtakes Firefox To Become the Second-Most Popular Browser
by Peter Reutemann 06 Apr '20

06 Apr '20

'It was probably just a matter of time, but the thing so many people, including everyone at Microsoft, expected finally happened: Microsoft Edge surpassed Mozilla Firefox to become the world's second most-used desktop browser. Data provided by market analysis firm NetMarketShare reveals that the whole thing happened in March, when the adoption of the Chromium-powered Microsoft Edge improved to a level that allowed it to overtake Mozilla's own browser. So right now, Microsoft Edge is the second most-used desktop browser on the planet with a share of 7.59%, while Mozilla Firefox is now third with 7.19%. As for who's leading the pack, Google Chrome continues to be number one with a share of 68.50%' -- source: https://news.slashdot.org/story/20/04/05/1727217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Eclipse Foundation Unveils Open Source Alternative to Microsoft's 'Visual Studio Code' IDE
by Peter Reutemann 05 Apr '20

05 Apr '20

'"The Eclipse Foundation just released version 1.0 of an open-source alternative to Visual Studio Code called Eclipse Theia," reports SD Times: Theia is an extensible platform that allows developers to create multi-language cloud and desktop IDEs, allowing them to create entirely new developer experiences. According to the Eclipse Foundation, the differences between Theia and Visual Studio Code are that Theia has a more modular architecture, Theia was designed from the ground to run on desktop and cloud, and Theia was developed under community-driven and vendor-neutral governance of the Eclipse Foundation. The Theia project was started by Ericsson and TypeFox in 2016, and since then it has become an integral part of cloud solutions globally. The project approached the Eclipse Foundation about becoming a potential host in 2019. Early contributors to the project include ARM, Arduino, EclipseSource, Ericsson, Google Cloud, IBM, Red Hat, SAP, and TypeFox. "We are thrilled to see Eclipse Theia deliver on its promise of providing a production-ready, vendor-neutral, and open source framework for creating custom and white-labeled developer products," announced Mike Milinkovich, the Eclipse Foundation's executive director. "Visual Studio Code is one of the world's most popular development environments. Not only does Theia allow developers to install and reuse VS Code extensions, it provides an extensible and adaptable platform that can be tailored to specific use cases, which is a huge benefit for any organization that wants to deliver a modern and professional development experience. Congratulations to all the Theia committers and contributors on achieving this milestone." InfoWorld points out that "thus far Theia is intended to be fitted into third-party products. An end-user version is on the roadmap for release later this year." But programming columnist Mike Melanson notes that "Chances are, you've already run into Theia without even realizing it, as it already serves as the basis for Red Hat's CodeReady Workspaces, the Eclipse Foundation's own Eclipse Che, and Google Cloud Shell."' -- source: https://developers.slashdot.org/story/20/04/04/1819251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

What's New in Linux 5.6? WireGuard VPN and USB4
by Peter Reutemann 05 Apr '20

05 Apr '20

'Linux 5.6 "has a bit more changes than I'd like," Linus Torvalds posted on the kernel mailing list, "but they are mostly from davem's networking fixes pulls, and David feels comfy with them. And I looked over the diff, and none of it looks scary..." TechRadar reports that the new changes include support for USB4 and GeForce RTX 2000 series graphics cards with the Nouveau driver: Yes, Turing GPU support has arrived with the open source Nouveau driver, along with the proprietary firmware images, as Phoronix.com reports. However, don't get too excited, as re-clocking doesn't work yet (getting the GPU to operate at stock clocks), and other important pieces of the puzzle are missing (like no Vulkan support with Nouveau). For the unfamiliar, Nouveau is an alternative to Nvidia's proprietary drivers on Linux, and although it remains in a relatively rough state in comparison, it's still good to see things progressing for Linux gamers with one of Nvidia's latest cards in their PC. Linux 5.6 also introduces fresh elements on the AMD front, with better reset support for Navi and Renoir graphics cards (which helps the GPU recover if it hits a problem)... Another notable move is the introduction of WireGuard support, a newcomer VPN protocol which makes a potentially nifty alternative to OpenVPN. Linux 5.6 also supports the Amazon Echo speaker, and naturally comes with a raft of other minor improvements... Linus's post also notes that for the next release's timing they'll "play it by ear... It's not like the merge window is more important than your health, or the health of people around you." But he says he hasn't seen signs that the pandemic could affect its development (other than the possibility of distraction by the news). "I suspect a lot of us work from home even normally, and my daughter laughed at me and called me a 'social distancing champ' the other day..."' -- source: https://linux.slashdot.org/story/20/04/04/2128207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

U.S. Government: Update Chrome 80 Now, Multiple Security Concerns Confirmed
by Peter Reutemann 05 Apr '20

05 Apr '20

'Part of America's Department of Homeland Security, the Cybersecurity and Infrastructure Security Agency (CISA) "has advised users to update Google Chrome as new high-rated security vulnerabilities have been found," reports Forbes: In an April 1 posting, CISA confirmed that Google Chrome version 80.0.3987.162 "addresses vulnerabilities that an attacker could exploit to take control of an affected system," be that Windows, Mac or Linux. It went on to state that it "encourages" users and administrators to apply the update. It's not just CISA that is warning about the need to update Google Chrome. The Center for Internet Security (CIS) is a non-profit entity that works to safeguard both private and public organizations against cyber threats. In a multi-state information sharing and analysis center (MS-ISAC) advisory, it has also warned of multiple vulnerabilities in Google Chrome. The most severe of these could allow an attacker to achieve arbitrary code execution within the context of the browser... All it would take for an attacker to exploit the vulnerabilities is to get the user to visit, by way of a phishing attack or even redirection from a compromised site, a maliciously crafted web page. Beside three high-rated vulnerabilities, Forbes reports that "a further five security vulnerabilities were discovered by the Google internal security team using a combination of internal audits and fuzzing."' -- source: https://it.slashdot.org/story/20/04/04/2020211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Cheap 3D Printer Review
by Lawrence D'Oliveiro 05 Apr '20

05 Apr '20

Here’s a review <https://www.youtube.com/watch?v=M3SMUpNH_6I> of a sub-USD100 3D printer from China. Has some good discussion of quality issues in 3D printing generally, and how this relates to the printer versus the filament you use. And I learned about the “3DBenchy” benchmark reference model. Judging from the gear they have access to, LTT seems to have quite a high budget for a YouTube channel. Also some useful notes from knowledgeable users among the comments ... if you can be bothered to dig for them ...

Yet Another Processor Architecture
by Lawrence D'Oliveiro 05 Apr '20

05 Apr '20

Here’s a report <https://www.nextplatform.com/2020/04/02/tachyum-starts-from-scratch-to-etch…> on a startup creating another new, proprietary processor architecture. Proprietary or not, the standard thing to do to get software running on things like this seems to be to port the GNU toolchain. Kernel? OS? No mention of that at this stage. I don’t claim to understand all the details, but it seems to be taking ideas from lots of sources, including Intel’s Itanium (which failed to become a successor to x86). One thing I was surprised to learn is that, as the wires connecting the transistors on a chip get thinner, this also makes them slower. So you don’t get all the gain you were expecting from making them shorter and bringing things closer together. One thing is clear: the Great Wheel Of Reincarnation <https://www.deviantart.com/default-cube/art/Computer-Graphics-And-The-Wheel…> (which in this case would apply to computing generally, not just graphics) has yet to stop spinning ...

Vint Cerf 'No Longer Contagious' With Covid-19
by Peter Reutemann 05 Apr '20

05 Apr '20

'Good news — VA Public Health has certified my wife and me as no longer contagious with COVID19," tweeted 76-year-old Vint Cerf, one of the creators of the modern internet. He added one word. "Recovering!" It seemed especially appropriate that Cerf shared his news online — and that it drew positive responses from grateful people around the world, including several who use the internet in their daily lives. Cerf's tweet immediately drew positive responses from the Internet Society, as well as the chief operating officer of the Cloud Native Computing Foundation, YouTube's director of public policy, and a senior director of communications and public affairs at Google. There were also congratulatory posts from a Georgetown professor of technology and law, from Associated Press reporter Frank Bajak, and the executive director of the Global Privacy and Security by Design Centre. Cerf followed up his news with a re-tweet of Google's "Community Mobility Reports" charting our aggregate movement trends over time, and a tweet of a University of Pittsburgh press release about progress on a COVID-19 vaccine candidate. Earlier in the week Cerf also re-tweeted a humorous compilation of clips from the TV show M*A*S*H that illustrated safe practices while social distancing.' -- source: https://news.slashdot.org/story/20/04/04/0615234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Will Google Allow An Independent Peek At Its Crown Jewels?
by Lawrence D'Oliveiro 04 Apr '20

04 Apr '20

An advertising company called Foundem is suing Google <https://www.theregister.co.uk/2020/04/03/google_foundem_high_court_seo_expe…> over a drastic demotion in its search rankings and consequent damage to its business, claiming this was an anticompetitive act. Google denies this, and as part of its defence has filed documents with the court giving confidential details of how its search-ranking algorithms work. But of course the lawyers and judge don’t have the background to understand these documents. So the plaintiff wants an independent SEO expert to be able to go over them and make sense of them to the lawyers. Google is vehemently opposed to this. So now the judge has given the company a stark choice: either allow the expert access to those documents, or withdraw them from the evidence (and thereby, by Google’s own admission as to the “vital” nature of these documents for its defence, likely lose the case). Which way do you think Google will decide?

Phone-tracking of self-isolationists
by tom butz 04 Apr '20

04 Apr '20

When we had to track teenagers' nightclubbing whereabouts (they're adults now), we did the following: 1) made sure we'd written down their mobile phone-numbers (obviously) 2) remembered their names/addresses (obviously) 3) told them to leave their mobiles switched ON all the time (they'd have done that anyway to keep up with Social Media) 4) Sent them a text every hour on the hour and they'd have to reply 'OK'. We'd reimburse them the money for the texts (nice little earner if you're on a plan...). Side-effect: it boosted their self-esteem (wow, getting messages all the time - she must be popular). Was that asking too much? Fast forward to our current lockdown and the way to handle self-quarantine: 1) as above 2) as above 3) as above 4) get info from cellphone-towers to check which one they're logged in. If, for example, someone is in self-quarantine at an Auckland campground and all of a sudden's logged into the Gisborne cell-tower, that would be an indication that they're elsewhere - or that the phone had been stolen. Note that in the case of traffic accidents police already get the info from cell-towers, so they can determine if the driver - according to their phone - was in the area, logged on and texting. Piece of cake for them, according to TVNZ. BTW, there is no need for name-matching: the rental-car companies do that anyway, so the user's name could stay anonymous - until police very kindly ask/beg cap in hand for it to be released.

The Internet is Now Rife With Places Where You Can Organize Zoom-bombing Raids
by Peter Reutemann 03 Apr '20

03 Apr '20

'The internet is rife with online communities where users can go and share Zoom conference codes and request that pranksters connect and hurl insults, play pornographic material, or make death threats against other participants -- in a practice called Zoom-bombing or a Zoom raid. From a report: ZDNet began tracking the tactic since mid-March when the term was first coined following a TechCrunch article. Ever since then, Zoom-bombing incidents have increased, as articles in major news outlets like the New York Times and the BBC have made the practice a favorite pastime for all the teenagers stuck in their homes during the current coronavirus (COVID-19) quarantines. From a niche prank that started on a derelict Discord channel, Zoom-bombing has now spread to enormous proportions -- being so rampant these days that the FBI sent a nationwide alert last week, urging companies, schools, and universities to take steps to secure their Zoom channels. But as Zoom-bombing became more popular, more pranksters wanted to join on the fun, and more users wanted their friends' Zoom meetings disrupted. And as the old saying goes; where there's a demand, there's always a supply. Over the course of the past week, the number of places on the public internet where you can request a zoom raid from a gang of bored teenagers has exploded.' -- source: https://yro.slashdot.org/story/20/04/02/1937229 How to secure Zoom: https://www.netsafe.org.nz/get-into-zoom/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

OpenWRT code-execution bug puts millions of devices at risk
by Peter Reutemann 01 Apr '20

01 Apr '20

'For almost three years, OpenWRT—the open source operating system that powers home routers and other types of embedded systems—has been vulnerable to remote code-execution attacks because updates were delivered over an unencrypted channel and digital signature verifications are easy to bypass, a researcher said. OpenWRT has a loyal base of users who use the freely available package as an alternative to the firmware that comes installed on their devices. Besides routers, OpenWRT runs on smartphones, pocket computers and even laptops and desktop PCs. Users generally find OpenWRT to be a more secure choice because it offers advanced functions and its source code is easy to audit. Security researcher Guido Vranken, however, recently found that updates and installation files were delivered over unencrypted HTTPs connections, which are open to attacks that allow adversaries to completely replace legitimate updates with malicious ones. The researcher also found that it was trivial for attackers with moderate experience to bypass digital-signature checks that verify a downloaded update as the legitimate one offered by OpenWTR maintainers. The combination of those two lapses makes it possible to send a malicious update that vulnerable devices will automatically install.' -- source: https://arstechnica.com/information-technology/2020/03/openwrt-is-vulnerabl… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How The ESA Has Kept The Mars Express Probe Doing Useful Science For 16 Years
by Lawrence D'Oliveiro 01 Apr '20

01 Apr '20

Originally designed for a mission lasting one Martian year (about two Earth years), MEX <https://www.theregister.co.uk/2020/03/31/mars_express/> continues to operate even today, and looks likely to manage to stay in action for a few more years. Working around a wiring error that meant it only had 70% of the designed operating power, then dealing with unreliabilities cropping up in the Solid-State Mass Memory system, figuring out how to prolong the life of the maneouvring reaction wheels, actually having to write and upload new software written in Ada-83, where the original contractor was helpful, rather than obstructive for a change: While support had officially ended, ESA did set up a small contract with Airbus (who had acquired the original spacecraft manufacturer) in a role reversal that saw Airbus review the MEX team's work rather than the other way around. As it transpired, Airbus turned out to be hugely helpful, blowing dust off some testing tools, making suggestions and, effectively, "putting the band back together" as those who originally designed and built MEX (and had not yet shuffled off into retirement) were hauled back to offer assistance. All in all, the team operating MEX has done some amazing work so far. Bear in mind that launching probes into space is still a dicey business, prone to embarrassing failures. This is why they have to be over-engineered, then backed up with alternate recovery plans on top of alternate recovery plans.

Zoom Meetings Aren't End-to-End Encrypted, Despite Misleading Marketing
by Peter Reutemann 01 Apr '20

01 Apr '20

'Zoom, the video conferencing service whose use has spiked amid the Covid-19 pandemic, claims to implement end-to-end encryption, widely understood as the most private form of internet communication, protecting conversations from all outside parties. In fact, Zoom is using its own definition of the term, one that lets Zoom itself access unencrypted video and audio from meetings. With millions of people around the world working from home in order to slow the spread of the coronavirus, business is booming for Zoom, bringing more attention on the company and its privacy practices, including a policy, later updated, that seemed to give the company permission to mine messages and files shared during meetings for the purpose of ad targeting. Still, Zoom offers reliability, ease of use, and at least one very important security assurance: As long as you make sure everyone in a Zoom meeting connects using "computer audio" instead of calling in on a phone, the meeting is secured with end-to-end encryption, at least according to Zoom's website, its security white paper, and the user interface within the app. But despite this misleading marketing, the service actually does not support end-to-end encryption for video and audio content, at least as the term is commonly understood. Instead it offers what is usually called transport encryption.' -- source: https://it.slashdot.org/story/20/03/31/1526250 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Zoom is Leaking Peoples' Email Addresses and Photos To Strangers
by Peter Reutemann 01 Apr '20

01 Apr '20

'Popular video-conferencing Zoom is leaking personal information of at least thousands of users, including their email address and photo, and giving strangers the ability to attempt to start a video call with them through Zoom. From a report: The issue lies in Zoom's "Company Directory" setting, which automatically adds other people to a user's lists of contacts if they signed up with an email address that shares the same domain. This can make it easier to find a specific colleague to call when the domain belongs to an individual company. But multiple Zoom users say they signed up with personal email addresses, and Zoom pooled them together with thousands of other people as if they all worked for the same company, exposing their personal information to one another.' -- source: https://yro.slashdot.org/story/20/03/31/201237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'We've been anticipating WireGuard's inclusion into the mainline Linux kernel for quite some time—but as of Sunday afternoon, it's official. Linus Torvalds released the Linux 5.6 kernel, which includes (among other things) an in-tree WireGuard. Phoronix has a great short list of the most interesting new features in the 5.6 kernel, as well as a longer "everything list" for those who want to make sure they don't miss anything. If this is the first time you're hearing about WireGuard, the TL;DR is that it's a relatively new VPN (Virtual Private Network) application that offers a leaner codebase, easier configuration, faster connect times, and the latest and most thoroughly peer-reviewed and approved encryption algorithms. You can find a more detailed introduction in our initial August 2018 coverage.' -- source: https://arstechnica.com/gadgets/2020/03/wireguard-vpn-makes-it-to-1-0-0-and… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Parts of it, anyway. Currently having trouble accessing github.com and anz.co.nz. Well, what else is there to do? ;)
