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/

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/

Google Launches Braille Keyboard for Android Devices
by Peter Reutemann 10 Apr '20

10 Apr '20

'Google today announced the launch of a virtual braille keyboard for Android that's designed to enable those with low vision or blindness to type on their phones without additional hardware. From a report: The tech giant says it collaborated with braille developers and users to create it, and to ensure it can be used anywhere a user would normally type -- including social media, text messaging, and email apps. According to the World Health Organization, at least 2.2 billion people globally have a vision impairment or blindness. To address their needs, Google previously developed and released BrailleBack, an accessibility service for Android that helps users make use of braille devices, but BrailleBack didn't offer on-screen typing.' -- source: https://tech.slashdot.org/story/20/04/09/1831238 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.

Longtime Mozilla Leader Mitchell Baker is Now CEO
by Peter Reutemann 09 Apr '20

09 Apr '20

'On Wednesday, Mozilla chair and longtime leader Mitchell Baker was named permanent CEO of the company that makes the Firefox web browser. >From a report: Mitchell became interim CEO of Mozilla in December 2019, after former CEO Chris Beard resigned. The company conducted an external candidate search over the last eight months, and concluded the Mitchell is the right leader for Mozilla at this time, according to a company blog post published Wednesday. "Increasingly, numbers of people recognize that the internet needs attention," Baker said in another Mozilla blog post Wednesday. "Mozilla has a special, if not unique role to play here. It's time to tune our existing assets to meet the challenge. It's time to make use of Mozilla's ingenuity and unbelievable technical depth and understanding of the "web" platform to make new products and experiences. It's time to gather with others who want these things and work together to make them real."' -- source: https://tech.slashdot.org/story/20/04/08/1720218 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/
