Google Wants To Phase Out Browser User-Agent Strings
by Lawrence D'Oliveiro 21 Apr '20

21 Apr '20

Google wants to reduce the large amount of information browsers typically pack into the “User-Agent” header lines they send out, but this has been delayed for now <https://www.theregister.co.uk/2020/04/20/google_useragent_string_revision/>. This makes sense. Sites should not be changing their behaviour based on how browsers identify themselves, but on what functionality they actually support. But I wonder what this will mean for sites that routinely block the default user agents for scripting tools like wget and Python’s urllib ... But who is objecting to Google’s plan? Advertisers, who are apparently relying on user-agent checks as an important part of their mechanism for detecting ad fraud. Which is quite an incredible admission, really.

GhostBSD
by tom butz 21 Apr '20

21 Apr '20

There still are several BSDs around: OpenBSD, NetBSD, FreeBSD, TrueOS and GhostBSD. They usually lack desktops, but GhostBSD has got one, and it looks good. I started with the latest version, 20 something: that one didn't work properly for me Then I used 18.10 where there were issues with the LAN, and finally everything worked using 19.10 - both on my laptop and an old Macmini. BTW, I've also installed it on an external USB3-drive (500 GB) and it can boot from it. GhostBSD supports the ZFS-filesystem and will read/write from/to msdos and linux filesystems. I haven't tried writing to an ext4 system, only read from ext-sticks. You need to do some extra work to enable read/write to extfat. LAN and WiFi worked well and Firefox is very fast. My laptop has 6 GB of RAM and I ran everything in single-user mode, just to get some extra speed. Thanks go to Peter who found the older versions on a US-server - GhostBSD is made in Canada.

As Raspberry Pi Sales Skyrocket, Eben Upton Applauds Efforts of Open Hardware Community
by Peter Reutemann 20 Apr '20

20 Apr '20

'"Sales of Raspberry Pi's single-board computers hit 640,000 in March, the second-biggest month for sales since they started selling," reports TechRepublic, "as consumers flocked to inexpensive ways to work and learn from home." But that's not all, Eben Upton tells them: With the pandemic having highlighted shortages in personal protective equipment (PPE), 3D-printing manufacturers and hobbyists have been building face shields printed on plastic acetate that can be quickly assembled and delivered to hospitals, for free. "A lot of that is Pi-driven," Upton explained, noting that OctoPrint, which is the most popular platform for managing 3D printers, runs on Raspberry Pi... "[M]aking face shields seems to be a community effort. You have people with a home printer, printing these things once a week and then going to a post office and sending them," he said. "Then you'll have some people sat in a hack space receiving the parcels, cutting the acetate and the elastic, assembling them into face shields then sending them to the hospital. It's amazing." Upton suggested this effort could eventually be ramped up to a "massively distributed scale", with the benefit of open source being that, once you have a good design that works, it can be rapidly iterated. In the long term, this could even include the ventilators themselves, he said. "One thing we're seeing with this is people finding a niche within which open hardware really works," he said.

Will Companies Cut Open Source Investment Because of COVID-19?
by Peter Reutemann 20 Apr '20

20 Apr '20

'The editor of TFIR posed an interesting question to Rob Hirschfeld, the Founder/CEO of RackN (which automates and integrates bare-metal infrastructure). Will the financial impact of the COVID-19 pandemic affect the sustainability of open source software? Hirschfeld responded: "The idea that big companies are maintaining open-source projects for the community good is going to get tested, as companies look for places where they can conserve revenue. I think that's a really critical thing." "The same is going to be true with open-source startups that are hoping to monetize support or consulting but have no real gate across the front of their infrastructure... Companies might decide they can use the open-source project and not pay the sustaining engineers that are working in that project. "These are really serious concerns about the whole open-source model, which relies on goodwill and free money."' -- source: https://news.slashdot.org/story/20/04/19/0452247 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/

Supply-chain attack hits RubyGems repository with 725 malicious packages
by Peter Reutemann 20 Apr '20

20 Apr '20

'More than 725 malicious packages downloaded thousands of times were recently found populating RubyGems, the official channel for distributing programs and code libraries for the Ruby programming language. The malicious packages were downloaded almost 100,000 times, although a significant percentage of those are likely the result of scripts that automatically crawl all 158,000 packages available in the repository, Tomislav Pericin, the cofounder and chief software architect of security firm ReversingLabs, told Ars. All of them originated from just two user accounts: “JimCarrey” and “PeterGibbons.” The accounts, which ReversingLabs suspects may be the work of a single individual, used a variation of typosquatting—the technique of giving a malicious file or domain a name that's similar to a commonly recognizable name—to give the impression they were legitimate. For instance, “atlas-client,” a booby-trapped package with 2,100 downloads, was a stand-in for the authentic “atlas_client” package. More than 700 of the packages were uploaded from February 16 to 25.' -- source: https://arstechnica.com/information-technology/2020/04/725-bitcoin-stealing… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New Cloudflare tool can tell you if your ISP has deployed BGP fixes
by Peter Reutemann 20 Apr '20

20 Apr '20

'For more than an hour at the beginning of April, major sites like Google and Facebook sputtered for large swaths of people. The culprit wasn't a hack or a bug. It was problems with the internet data routing standard known as the Border Gateway Protocol, which had allowed significant amounts of web traffic to take an unexpected detour through a Russian telecom. For Cloudflare CEO Matthew Prince, it was the last straw. BGP disruptions happen frequently, generally by accident. But BGP can also be hijacked for large-scale spying, data interception, or as a sort of denial of service attack. Just last week, United States Executive Branch agencies moved to block China Telecom from offering services in the US, because of allegedly malicious activity that includes BGP attacks. Companies like Cloudflare sit on the front lines of the BGP blowback. And while the company can't fix the problem directly, it can call out those that are slow to contribute defenses.' -- source: https://arstechnica.com/information-technology/2020/04/new-cloudflare-tool-… 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/

Growth In Surveillance May Be Hard To Scale Back After Pandemic, Experts Say
by Peter Reutemann 19 Apr '20

19 Apr '20

Long-time Slashdot reader AmiMoJo quotes the Guardian: 'The coronavirus pandemic has led to an unprecedented global surge in digital surveillance, researchers and privacy advocates around the world have said, with billions of people facing enhanced monitoring that may prove difficult to roll back. Governments in at least 25 countries are employing vast programmes for mobile data tracking, apps to record personal contact with others, CCTV networks equipped with facial recognition, permission schemes to go outside and drones to enforce social isolation regimes. The methods have been adopted by authoritarian states and democracies alike and have opened lucrative new markets for companies that extract, sell, and analyse private data. One of the world's foremost experts on mobile phone surveillance said the pandemic had created a '9/11 on steroids' that could lead to grave abuses of power. "Most of these measures don't have sunset clauses. They could establish what many people are describing as a new normal," Ron Deibert, who heads the Citizen Lab at the University of Toronto, said in an interview with the Guardian. The article provides examples from China, Russia, India, Europe, and the United States, and provides a link to an index of new coronavirus-related surveillance measures related to the coronavirus outbreak. The digital rights lead at the group behind the list says "This isn't just an issue with authoritarian governments. This is happening across the world."' -- source: https://yro.slashdot.org/story/20/04/18/0717228 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 Tor Project Lays Off 37% of Its Staff
by Peter Reutemann 19 Apr '20

19 Apr '20

'The Tor Project's executive director Isabela Bagueros writes: Tor, like much of the world, has been caught up in the COVID-19 crisis. Like many other nonprofits and small businesses, the crisis has hit us hard, and we have had to make some difficult decisions. We had to let go of 13 great people who helped make Tor available to millions of people around the world. We will move forward with a core team of 22 people, and remain dedicated to continuing our work on Tor Browser and the Tor software ecosystem. The world won't be the same after this crisis, and the need for privacy and secure access to information will become more urgent. In these times, being online is critical and many people face ongoing obstacles to getting and sharing needed information. We are taking today's difficult steps to ensure the Tor Project continues to exist and our technology stays available. We are terribly sad to lose such valuable teammates, and we want to let all our users and supporters know that Tor will continue to provide privacy, security, and censorship circumvention services to anyone who needs them. Mashable reminds its readers that "Those wishing to make sure the specifics of their online browsing remain their own personal business can donate to Tor's non-profit organization. "Because with more and more of our lives happening online for the foreseeable future, it's a good idea to have an organization working to protect what little digital privacy we have left."' -- source: https://yro.slashdot.org/story/20/04/18/1129249 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/

After 8 Years of Remote-Access Trojans Attacks, Can We Still Say Linux is Secure?
by Peter Reutemann 19 Apr '20

19 Apr '20

'Remember when BlackBerry reported Advanced Persistent Threat groups have been infiltrating critical Linux servers for at least eight years? What's the lesson to be learned? LinuxSecurity Founder Dave Wreski argues "Although it may be easy to blame the rise in attacks targeting Linux in recent years on security vulnerabilities in the operating system as a whole, this is simply not the truth. The majority of exploits on Linux systems can be attributed to misconfigured servers and poor administration." Writing for Linux Security, Slashdot reader b-dayyy gathered some additional responses: Some experts argue that it is the popularity of Linux that makes it a target. Joe McManus, Director of Security at Canonical, explains: "Linux and, particularly Ubuntu, are incredibly secure systems but, that being said, it is their popularity that makes them a target." Ian Thornton-Trump, a threat intelligence expert and the CISO at Cyjax, adds: "From an economic and mission perspective, it makes sense for a threat actor to invest in open-source skills for flexibility and the ability to target the systems where the good stuff is happening." Despite the increasing number of threats targeting Linux systems, there is still a sound argument for the inherent security of Linux, which can be attributed to the core fundamentals of Open Source. Due to the transparency of open-source code and the constant scrutiny that this code undergoes by a vibrant global community, vulnerabilities are identified and remedied quicker than flaws that exist in the opaque source code of proprietary software and operating systems. Threat actors recognize this, and are still directing the majority of their attacks at proprietary operating systems. These attacks do; however, serve as a much-needed wakeup call for the security community that more needs to be done to protect Linux servers. BlackBerry's report reveals that security solutions and defensive coverage available within Linux environments is "immature at best". Endpoint protection, detection and response products are inadequately utilized by too many Linux users, and endpoint solutions available for Linux systems are often insufficient in combating advanced exploits. Eric Cornelius, Chief Product Officer at BlackBerry, evaluates: "Security products and services that support Linux, offerings that might detect and give us insight into a threat like this, are relatively lacking compared to other operating systems, and security research about APT use of Linux malware is also relatively sparse."

Linksys Asks Users To Reset Passwords After Hackers Hijacked Home Routers Last Month

'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.

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/

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....

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

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/

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/

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/
