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/

Meet dark_nexus, quite possibly the most potent IoT botnet ever
by Peter Reutemann 10 Apr '20

10 Apr '20

'A newly discovered botnet that preys on home routers, video recorders, and other network-connected devices is one of the most advanced Internet-of-things platforms ever seen, researchers said on Wednesday. Its list of advanced features includes the ability to disguise malicious traffic as benign, maintain persistence, and infect devices that run on at least 12 different CPUs. Researchers from antivirus provider Bitdefender described the so-called dark_nexus as a “new IoT botnet packing new features and capabilities that put to shame most IoT botnets and malware that we’ve seen.” In the three months that Bitdefender has tracked it, dark_nexus has undergone 30 version updates, as its developer has steadily added more features and capabilities.' -- source: https://arstechnica.com/information-technology/2020/04/meet-dark_nexus-quit… 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

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. From a report: In "Decade of the RATs: Cross-Platform APT Espionage Attacks Targeting Linux, Windows and Android," security researchers found that these groups have attacked companies around the world and across all industries with goals ranging from simple cybercrime to full-blown economic espionage. 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. The BlackBerry researchers think all five groups are working together, given the distinct similarities in their preferred tools, tactics, and procedures.' -- source: https://linux.slashdot.org/story/20/04/09/1538218 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Windows 10 Is Getting Linux Files Integration In File Explorer
by Peter Reutemann 09 Apr '20

09 Apr '20

'Microsoft is planning to fully integrate Linux file access into the built-in File Explorer. The Verge reports: A new Linux icon will be available in the left-hand navigation pane in File Explorer, providing access to the root file system for any distros that are installed in Windows 10. The icon that will appear in File Explorer is the famous Tux, the penguin mascot for the Linux kernel. Microsoft is testing the Linux File Explorer integration in a new build of Windows 10 that's available for testers today. Previously, Windows 10 users would have to manually navigate to a UNC path to get access to Linux files from the Windows Subsystem for Linux (WSL). If you have WSL enabled, then the Tux will appear in File Explorer, and Microsoft is now seeking feedback on the integration before it's finalized as part of a future Windows 10 update. The software maker will ship this update to all Windows 10 users later this year.

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

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 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.

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/

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

'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.

Twitter Discloses Firefox Bug That Cached Private Files Sent or Received via DMs
by Peter Reutemann 03 Apr '20

03 Apr '20

'Social networking giant Twitter today disclosed a bug on its platform that impacted users who accessed their platform using Firefox browsers. >From a report: According to Twitter, its platform stored private files inside the Firefox browser's cache -- a folder where websites store information and files temporarily. Twitter said that once users left their platform or logged off, the files would remain in the browser cache, allowing anyone to retrieve it. The company is now warning users who share workstations or used a public computer that some of their private files may still be present in the Firefox cache. Malware present on a system could also scrape and steal this data, if ever configured to do so.' -- source: https://news.slashdot.org/story/20/04/02/2048216 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 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/

Linux Mint 20 is 64-bit Only, Based on Ubuntu 20.04, and Named 'Ulyana'
by Peter Reutemann 01 Apr '20

01 Apr '20

'Today, we learn some new details about the upcoming Linux Mint 20. While most of the newly revealed information is positive, there is one thing that is sure to upset many Linux Mint users. First things first, Linux Mint 20 will be based on the upcoming Ubuntu 20.04. This shouldn't come as a surprise, as Mint only uses Long Term Support versions of Ubuntu, and 20.04 will be an LTS. We also now know the name of Linux Mint 20. The Mint team always uses female names, and this time they chose "Ulyana." This is apparently a Russian name meaning "youthful." So far, all of the news is positive, so what exactly will upset some users? The Linux Mint developers are finally dropping 32-bit support and will only produce 64-bit ISOs.' -- source: https://linux.slashdot.org/story/20/03/31/1842216 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/

WireGuard VPN makes it to 1.0.0—and into the next Linux kernel
by Peter Reutemann 31 Mar '20

31 Mar '20

'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/

Public Crash Screens: Linux For A Change

The exFAT Filesystem Is Coming To Linux -- Paragon Software's Not Happy About It

'When software and operating system giant Microsoft announced its support for inclusion of the exFAT filesystem directly into the Linux kernel back in August, it didn't get a ton of press coverage.

Yesterday, Paragon issued a press release about European gateway-modem vendor Sagemcom adopting its version of exFAT into an upcoming series of Linux-based routers. Unfortunately, it chose to preface the announcement with a stream of FUD (Fear, Uncertainty, and Doubt) that wouldn't have looked out of place on Steve Ballmer's letterhead in the 1990s.' -- source: https://linux.slashdot.org/story/20/03/25/2136223 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 Play’s malicious app problem infects 1.7 million more devices
by Peter Reutemann 25 Mar '20

25 Mar '20

'Google Play, the company’s official repository for Android apps, has once again been caught hosting fraudulent and potentially malicious apps, with the discovery of more than 56 apps—many of them for children—that were installed on almost 1.7 million devices. Tekya is a family of malware that generates fraudulent clicks on ads and banners delivered by agencies including Google’s AdMob, AppLovin’, Facebook, and Unity. To give the clicks the air of authenticity, the well-obfuscated code causes infected devices to use Android’s “MotionEvent” mechanism to imitate legitimate user actions. At the time researchers from security firm Check Point discovered them, the apps went undetected by VirusTotal and Google Play Protect. Twenty-four of the apps that contained Tekya were marketed to children. Google removed all 56 of the apps after Check Point reported them. The discovery “highlights once again that the Google Play Store can still host malicious apps,” Check Point researchers Israel Wernik, Danil Golubenko, and Aviran Hazum wrote in a post published on Tuesday. “There are nearly 3 million apps available from the store, with hundreds of new apps being uploaded daily–making it difficult to check that every single app is safe. Thus, users cannot rely on Google Play’s security measures alone to ensure their devices are protected.”' -- source: https://arstechnica.com/information-technology/2020/03/found-malicious-goog… 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/

Meet the Chinese OS That's Trying To Shift the Country Off Windows
by Peter Reutemann 25 Mar '20

25 Mar '20

'China's homegrown operating systems haven't made much of a dent on the global stage. Now there's a Linux-based system that's aimed at weaning the country off Windows. From a report: UOS, or Unified Operating System, hit a new milestone after its first stable release in January: Union Tech's OS can now boot in 30 seconds on China-made chips. It's an important step as Chinese tech companies look to reduce their dependence on US-made software and hardware. The struggles of ZTE and Huawei illustrate this clearly: The former was reliant on chips made in the US to produce smartphones, while the latter has the difficult task of selling Android handsets outside China without Google apps or services. The "current international climate" has made it imperative for China to have its own foundational software to avoid being cut off by the US, said the general manager of Union Tech, Liu Wenhan. While Chinese operating systems currently account for less than 1% of the market, Liu said he expects them to grow to 20% to 30% in the future. Integrating homegrown Chinese chips could be the biggest accomplishment of UOS if it pans out. Although Chinese computer chips still don't approach the sophistication of those created by US-based companies, Union Tech said that it is actively working with Chinese chipmakers like Loongson and Sunway to facilitate the gradual replacement of American technology in the Chinese government and pillar industries. In December, Beijing ordered all government offices and public institutions to remove foreign computer equipment and software within three years.' -- source: https://tech.slashdot.org/story/20/03/24/1918223 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 Says Hackers Are Attacking Windows Users With a New Unpatched Bug

'Microsoft says attackers are exploiting a previously undisclosed security vulnerability found in all supported versions of Windows, including Windows 10. From a report: But the software giant said there is currently no patch for the vulnerability. The security flaw, which Microsoft deems "critical" -- its highest severity rating -- is found in how Windows handles and renders fonts, according to the advisory posted Monday. The bug can be exploited by tricking a victim into opening a malicious document. Once the document is opened -- or viewed in Windows Preview -- an attacker can remotely run malware, such as ransomware, on a vulnerable device. The advisory said that Microsoft was aware of hackers launching "limited, targeted attacks," but did not say who was launching the attacks or at what scale.' -- source: https://tech.slashdot.org/story/20/03/23/1846216 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/

WLUG meeting (virtual)
by Peter Reutemann 23 Mar '20

23 Mar '20

Hi everyone Thanks to Aarons tireless efforts, we can have our WLUG meeting despite COVID-19, though in virtual form via Youtube and Google Hangouts (see links below). As a refresher for the topic: The voice interface represents another big shift in user interfaces, and could be as big a shift as the shift from switches to terminals, the switch from terminals to windowed GUIs, or the switch from full computers to small touchscreen devices. Unfortunately, right now most of these devices are little more than a telephone for talking to a server in the cloud. That is a big problem for privacy, and presents the user with a false choice between access and privacy. Today's computers are capable of handling a verbal interface without requiring a cloud service to handle all of your requests. Aaron Chantrill is one of the developers on the Naomi Project, a free and open source voice assistant (https://projectnaomi.com) It is a plugin based system based on Jasper (http://jasperproject.github.io/) and depending on how the user chooses to configure it, can run totally offline. In this presentation, Aaron would like to introduce people to the Naomi Project, talk about the benefits of a verbal interface, talk about the current architectures of virtual assistants, and ways in which that architecture can be altered to provide better privacy, and also do a comparison of offline speech to text and text to speech solutions, including Pocketsphinx, Mozilla Deepspeech, Kaldi, and Julius. Finally, He will invite people to participate in building and improving Naomi. There is a lot to do and much of it is both engaging and cutting-edge. Aaron recorded a video of his presentation that you can watch here before the virtual meeting: https://youtu.be/8383A_t7iKQ The slides are available as well: https://github.com/aaronchantrill/NaomiPresentation/raw/master/Presentation… The Google Hangouts link for the Question & Answer session: https://hangouts.google.com/hangouts/_/calendar/ZHJhc2t5QGdtYWlsLmNvbQ.3j6l… Meetup link: https://www.meetup.com/WaikatoLinuxUsersGroup/events/269578787/ 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/

[OT] The Doctor Who Helped Defeat Smallpox Explains What’s Coming

I realize this isn’t part of the topic of this group, but this article <https://arstechnica.com/science/2020/03/the-doctor-who-helped-defeat-smallp…> seems to me important enough that everyone should read it. It’s an interview with epidemiologist Larry Brilliant, who was part of the group that helped eradicate smallpox, and who gave a TED talk 14 years ago about what the next epidemic would look like, that is proving rather prescient right now. He gives an overview of where we are at in the knowledge of the SARS-Cov-2† virus that is causing the current COVID-19‡ pandemic. In short, as new as this virus is, it’s going to follow a lot of the same sort of behaviour as every past infectious viral disease. On facemasks: The N95 mask itself is extremely wonderful. The pores in the mask are three microns wide. The virus is one micron wide. So you get people who say, well, it's not going to work. But you try having three big, huge football players who are rushing for lunch through a door at lunchtime—they're not going to get through. In the latest data I saw, the mask provided 5x protection. That's really good. But we have to keep the hospitals going and we have to keep the health professionals able to come to work and be safe. So masks should go where they’re needed the most: in taking care of patients. †Official name of the virus ‡Official name of the disease caused by the virus

Critical bugs in dozens of Zyxel and Lilin IoT models under active exploit
by Peter Reutemann 22 Mar '20

22 Mar '20

'Criminals are exploiting critical flaws to corral Internet-of-things devices from two different manufacturers into botnets that wage distributed denial-of-service attacks, researchers said this week. Both DVRs from Lilin and storage devices from Zyxel are affected, and users should install updates as soon as possible. Multiple attack groups are exploiting the Lilin DVR vulnerability to conscript them into DDoS botnets known as FBot, Chalubo, and Moobot, researchers from security firm Qihoo 360 said on Friday. The latter two botnets are spinoffs of Mirai, the botnet that used hundreds of thousand of IoT devices to bombard sites with record-setting amounts of junk traffic. The DVR vulnerability stems from three flaws that allow attackers to remotely inject malicious commands into the device. The bugs are: (1) hard-coded login credentials present in the device, (2) command-injection flaws, and (3) arbitrary file reading weaknesses. The injected parameters affect the device capabilities for file transfer protocol, network time protocol, and the update mechanism for network time protocol.' -- source: https://arstechnica.com/information-technology/2020/03/lilin-dvrs-and-zyxel… 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/

Using Employer’s Proprietary Software From Home? It’ll Cost You

Never mind the security pitfalls of employees working from home, now there are additional licensing headaches to worry about as well, with proprietary software <https://www.theregister.co.uk/2020/03/20/surge_in_home_working/>: ... some vendors have curious rules about remote access to their applications that incur additional fees. Rich Gibbons, a licensing trainer at IT Asset Management (ITAM), noted that Citrix and/or Remote Desktop Services are "the easiest way to quickly become non-compliant with a LOT of vendors." ... Security is one thing, but in the midst of a global pandemic, does anyone care about licensing? "You're not going to get audited right now," Gibbons told The Reg. "But in six months or whenever this is over, you need to know what you've done."

'In a great example of what can happen when smart, technically-oriented people come together in a time of need, an open-source hardware project started by a group including Irish entrepreneur Colin Keogh and Breeze Automation CEO and co-founder Gui Calavanti has produced a prototype ventilator using 3D-printed parts and readily available, inexpensive material. The ventilator prototype was designed and produced in just seven days, after the project spun up on Facebook and attracted participation from over 300 engineers, medical professionals and researchers. The prototype will now enter into a validation process by the Irish Health Services Executive (HSE), the country's health regulatory body. This will technically only validate it for use in Ireland, which ironically looks relatively well-stocked for ventilator hardware, but it will be a key stamp of approval that could pave the way for its deployment across countries where there are shortages, including low-income nations. The group behind the ventilator also recently changed the focus of their Facebook community, renaming the group from the Open Source Ventilator Project to the Open Source COVID19 Medical Supplies community. They're looking at expanding their focus to finding ways to cheaply and effectively build and validate other needed equipment, including protective gear like masks, sanitizer and protective face guards for front-line healthcare workers.' -- source: https://science.slashdot.org/story/20/03/19/2047232 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/
