Caddy offers TLS, HTTPS, and more in one dependency-free Go Web server
by Peter Reutemann 07 May '20

07 May '20

'Yesterday, the Caddy Web server reached an important milestone, with its 2.0.0 release. Caddy bills itself as "The Ultimate Server," with no dependencies, automatic TLS certificate obtainment and renewal, and much smaller configuration files than Apache or Nginx. Senior Technology Editor Lee Hutchinson expressed both curiosity about Caddy and his own personal inertia in the Ars slack: Caddy is an app where every time i see it or think of it i say “I should mess with it, it looks neat” and then I never do. I’ve gotten so enmeshed in my haproxy - varnish - nginx stack that breaking out feels like more trouble than it’s worth. I hadn't ever heard of Caddy until Lee mentioned it, but I know a call to action when I hear one.' -- source: https://arstechnica.com/gadgets/2020/05/caddy-offers-tls-https-and-more-in-… 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 76 Arrives With Password Management and Zoom Improvements
by Peter Reutemann 06 May '20

06 May '20

'Mozilla today launched Firefox 76 for Windows, Mac, and Linux. Firefox 76 includes new Firefox Lockwise password functionality, Zoom improvements, and a handful of developer features. From a report: Lockwise, the password management service formerly known as Firefox Lockbox, is getting smarter. The Firefox feature already lets you generate, manage, and protect all those passwords for streaming services, grocery deliveries, and anything else that helps during the pandemic. If you share your device with family or roommates, Lockwise in Firefox 76 can now protect your saved passwords. When you try to view or copy a password from your "Logins and Passwords" page, you will be prompted for your device's account password. [...] Firefox 76 adds support for Audio Worklets, which run custom JavaScript audio processing code for applications like VR and gaming on the web. Unlike their predecessor, ScriptProcessorNode, worklets run off the main thread in a similar way to web workers. Mozilla also notes Audio Worklets are "being adopted by some of your favorite software programs." The company specifically called out Zoom, which has become a phenomenon of its own during the pandemic. In short, you now join Zoom calls in Firefox without having to download or install the Zoom client.' -- source: https://news.slashdot.org/story/20/05/05/160252 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/

Xiaomi Releases Browser Update Amid Accusations It Collects Private Browsing Data
by Peter Reutemann 06 May '20

06 May '20

'Xiaomi released software updates for its browser apps on Monday amid fresh accusations it's been collecting private data from people who use its phones and browser apps. CNET reports: In a blog post, Xiaomi said the update will allow you to switch off aggregated data collection while on incognito mode in its three browser apps: Mi Browser, Mi Browser Pro, and Mint Browser. The software update was rolled out on Google Play. "We believe this functionality, in combination with our approach of maintaining aggregated data in non-identifiable form, goes beyond any legal requirements and demonstrates our company's commitment to user privacy," the company said in its post. The release of the software update comes after a Forbes report published last Thursday raised concerns about the Chinese phone-maker's use of private data. It suggested Xiaomi may be collecting data on the websites users visit as well as granular information about apps used and files opened on devices. In response to the report, Xiaomi defended its practices last week saying it's "fully compliant with user privacy protection laws and regulations in the countries and regions we operate in.' -- source: https://yro.slashdot.org/story/20/05/05/2013244 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/

Ubuntu 20.04: Welcome to the future, Linux LTS disciples
by Peter Reutemann 05 May '20

05 May '20

'This is most definitely the strangest spring in a very long time, with all sorts of event and hardware delays or outright cancellations. But one thing that has arrived right on schedule? The latest version of Ubuntu Linux. Ubuntu 20.04 (Focal Fossa, as this release is known) is a Long Term Support (LTS) release, which means Ubuntu's parent company, Canonical, will provide support through 2025. The LTS releases are what Canonical calls "enterprise grade," and these tend to be conservative when it comes to adopting new technologies. The interim releases, like last year's Ubuntu 19.10, are instead where the company tends to experiment. Perhaps not surprisingly, Canonical estimates that 95 percent of all Ubuntu installations are LTS releases. Which is to say, this is a big update that the bulk of Ubuntu's user base will be upgrading to eventually. The good news for Ubuntu fans is that 20.04 has been a fantastic release in our testing. This update has been very solid in day-to-day use, and it still manages to (optionally!) include support for some cutting-edge new features, like the beginnings of a tool to manage ZFS snapshots. There's also a major kernel bump, and considerable work has gone into improving and polishing the default Yaru theme. That's a running theme in Ubuntu, where much of what makes it great are small changes and new features that individually might not be remarkable but all together create a system that is fast, stable, and hard to beat. The security improvements offered this time around almost alone make Ubuntu 20.04 a must-have upgrade. But the Ubuntu 20.04 update has plenty of new stuff for all the various Ubuntu flavors as well. So even if the default GNOME desktop doesn't excite you, there's big news in Kubuntu, Lubuntu, Ubuntu Mate, and more. There's also some good news for Raspberry Pi users, who get first-class support for the Pi 4 platform out of the box (and when I say first class, I mean, frankly, better than the official Pi distro, Raspian).' -- source: https://arstechnica.com/information-technology/2020/05/ubuntu-20-04-welcome… 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/

Academics Turn PC Power Units Into Speakers To Leak Secrets From Air-Gapped Systems
by Peter Reutemann 05 May '20

05 May '20

'Academics from an Israeli university have published new research last week showing how an attacker could turn a computer's power supply unit into a rudimentary speaker that can secretly transmit data from an infected host using audio waves. From a report: The technique, named POWER-SUPPLaY, is the work of Mordechai Guri, the head of R&D at the Ben-Gurion University of the Negev, in Israel. Over the last half-decade, Guri has been pioneering research into new covert data exfiltration channels. The techniques Guri has been developing can be used for stealing data through unconventional means. Guri has been developing these techniques specifically for extracting data from air-gapped systems -- computers isolated on local networks with no internet access. Such computers are often used on government or corporate networks to store sensitive data, such as classified files or intellectual property. Air-gapped systems are protected by several layers of defenses, on top of the "air gap," and you need novel data transmission techniques to go around these defenses. For example, some air-gapped systems don't have speakers, because it's been proven in the past that speakers could be abused to leak information from a secure system using inaudible sound waves.' -- source: https://it.slashdot.org/story/20/05/04/176208 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 Purged Almost 1,000 Abusive 'Creeperware' Apps. Now Some Are Coming Back.
by Peter Reutemann 05 May '20

05 May '20

'In June 2019, a group of cybersecurity researchers notified Google of more than 1,000 potentially malicious apps on the company's Play Store that can be used to surveil, monitor, and harass users. Their findings, which have not previously been reported, eventually led to one of the largest ever mass removals of Android apps. Less than a year later, there are signs that the "creeperware," as the researchers called it, is returning. From a report: The label comprises a broad category of abusable apps, including tools for spying, spoofing phone numbers, and secretly recording video and audio. Some of those programs banned by Google have now rebranded or added disclaimers and returned to the Play Store. Meanwhile, new programs with overtly abusive purposes have slipped through the company's automated monitoring systems. The initial 1,095 apps flagged by researchers came in a variety of forms. Catch Cheating Spouse and its ilk offered stalkerware packages: Once installed on a victim's phone, the user could track the device's location, read messages, listen to calls, remotely record through the microphone, or log passwords. Many of the programs had innocuous names but hostile purposes. Spoof Text Message, for example, advertised itself with a video using the tagline "Don't like your buddy's girlfriend? Well, break them up!" Others, like GirlFriend Cell Tracker, were more explicit in their motivation. "When we reported these apps to Google initially, it felt like they didn't really know what to do with them," said Kevin Roundy, the technical director of NortonLifeLock's research group, and one of the lead members of the team that uncovered the malicious apps last June.' -- source: https://tech.slashdot.org/story/20/05/04/1528219 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/

Hackers Breach LineageOS Servers Via Unpatched Vulnerability
by Peter Reutemann 05 May '20

05 May '20

'Hackers have gained access to the core infrastructure of LineageOS, a mobile operating system based on Android, used for smartphones, tablets, and set-top boxes. The intrusion took place on Saturday night at around 8 pm (US Pacific coast), and was detected before the attackers could do any harm, the LineageOS team said in a statement published less than three hours after the incident. The LineageOS team said the operating system's source code was unaffected, and so were any operating system builds, which had been already paused since April 30, because of an unrelated issue. Signing keys, used to authenticate official OS distributions, were also unaffected, as these hosts were stored separately from the LineageOS main infrastructure. LineageOS developers said the hack took place after the attacker used an unpatched vulnerability to breach its Salt installation.' -- source: https://it.slashdot.org/story/20/05/04/0341202 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 Keeps Developers Happy? Contributing to Open Source
by Peter Reutemann 04 May '20

04 May '20

'This week long-time open source advocate Matt Asay warned employers that the best way to keep their developers happy was to let them contribute to open source projects: SlashData recently surveyed over 16,000 developers to see what makes them tick... what they care about. The data is collected in SlashData's State of the Developer Nation, though let me give you the tl;dr: 59% of developers contribute to open source software today. Why do they contribute? The top two reasons are: To improve coding skills and because they believe in open source. Want to keep those developers happy and employed with you? Let them contribute... [Y]our employees want to contribute both code and knowledge — they want to be part of something. Talking to Bert Hubert, founder of PowerDNS, a supplier of open source DNS software, services, and support, he stressed that an open source project must be "a fun place where people feel that they are learning things, that they're contributing things, that they're being valued." Perhaps not surprisingly, these are the same elements developers expect from their employers. By making open source a valued part of workplace expectations, employers tick both boxes. Is it an absolute requirement that you encourage your developers to contribute to open source projects? No. But many of your best developers will chafe at keeping their talents locked up behind the firewall, and other developers simply won't apply if you have a reputation for being an open source scrooge. The article was written by Matt Asay, a former COO of Canonical now working at AWS. (Right before becoming Canonical's COO, Matt answered questions from Slashdot readers). The survey he cites also found that out of 17,000 developers they talked to, just 3% said they were paid to contribute to open source. The other 97% contributed for free.' -- source: https://news.slashdot.org/story/20/05/03/1746244 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/

Copyleft and the Cloud: Where Do We Go From Here?

'Free software evangelist Jeremy Allison - Sam (Slashdot reader #8,157) is a co-creator on the Samba project, a re-implementation of SMB/CIFS networking protocol, and he also works in Google's Open Source Programs Office. Now he shares his presentation at the Software Freedom Conservancy's "International Copyleft Conference." He writes: The Samba project has traditionally been one of the strongest proponents of Copyleft licensing and Free Software. However, in the Corporate Cloud-first world we find ourselves, traditional enforcement mechanisms have not been effective. How do we achieve the goals of the Free Software movement in this new world and how do we need to change what we're doing to be successful ? Traditional license enforcement doesn't seem to work well in the Cloud and for the modern software environment we find ourselves. In order to achieve the world of Free Software available for all I think we need to change our approach. Both GPLv3 and the AGPL have been rejected soundly by most developers. I would argue that we need a new way to inspire developers to adopt Free Software goals and principles, as depending on licensing has failed as licensing itself has fractured. Communication and collaboration are key to this. Stand-alone software is essentially useless. Software interoperability and published protocol and communication definitions are essential to build a freedom valuing software industry for the future The talk's title?

Google's reCAPTCHA Is Being Used To Hide Phishing Pages

'New research from Barracuda Networks has revealed that cyber-criminals are increasingly using official reCAPTCHA walls to disguise malicious content from email security systems and trick unsuspecting users... [S]ophisticated scammers are beginning to use the Google-owned service to prevent automated URL analysis systems from accessing the actual content of phishing pages, and to make phishing sites more believable in the eyes of the victim, Barracuda Networks warned. In fact, the security solutions provider observed a single phishing campaign that sent out 128,000 emails to a variety of organizations and employees using reCAPTCHA walls to conceal fake Microsoft log-in pages. This campaign used the lure of a voicemail receipt to fool users into solving the reCAPTCHA wall before being redirected to the malicious page, with any log-in info entered then sent straight to the scammers.' -- source: https://tech.slashdot.org/story/20/05/03/1613229 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/

Xiaomi Found Recording 'Private' Web and Phone Use, Researchers Claim
by Peter Reutemann 01 May '20

01 May '20

'According to an exclusive report from Forbes, cybersecurity researcher Gabi Cirlig discovered that his Xiaomi Redmi Note 8 smartphone was watching much of what he was doing and sending that data to remote servers hosted by Chinese tech giant Alibaba, which were ostensibly rented by Xiaomi. From the report: The seasoned cybersecurity researcher found a worrying amount of his behavior was being tracked, whilst various kinds of device data were also being harvested, leaving Cirlig spooked that his identity and his private life was being exposed to the Chinese company. When he looked around the Web on the device's default Xiaomi browser, it recorded all the websites he visited, including search engine queries whether with Google or the privacy-focused DuckDuckGo, and every item viewed on a news feed feature of the Xiaomi software. That tracking appeared to be happening even if he used the supposedly private "incognito" mode. The device was also recording what folders he opened and to which screens he swiped, including the status bar and the settings page. All of the data was being packaged up and sent to remote servers in Singapore and Russia, though the Web domains they hosted were registered in Beijing. Meanwhile, at Forbes' request, cybersecurity researcher Andrew Tierney investigated further. He also found browsers shipped by Xiaomi on Google Play -- Mi Browser Pro and the Mint Browser -- were collecting the same data. Together, they have more than 15 million downloads, according to Google Play statistics. Cirlig thinks that the problems affect many more models than the one he tested. In response to the findings, Xiaomi said, "The research claims are untrue," and "Privacy and security is of top concern," adding that it "strictly follows and is fully compliant with local laws and regulations on user data privacy matters." A spokesperson did however confirm it was collecting browsing data, claiming the info was anonymized and users had consented to it. Cirlig and Tierney pointed out that Xiaomi "was also collecting data about the phone, including unique numbers for identifying the specific device and Android version," reports Forbes. "Cirlig said such 'metadata' could 'easily be correlated with an actual human behind the screen.'" The researchers also say they found their Xiaomi apps to be sending data to domains that appeared to reference Sensor Analytics, which Xiaomi says "provides a data analysis solution for Xiaomi," adding that that the collected anonymous data "are stored on Xiaomi's own servers and will not be shared with Sensor Analytics, or any other third-party companies."' -- source: https://yro.slashdot.org/story/20/04/30/237249 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/

Distro Showdown May

01 May '20

I have just checked microphone/camera on my Toshiba laptop running Mint 19.3: they're both ok for a remote meeting. What I could do is talk about the various Linuxes I have used, starting witn Tiny Linux, then Arch-Linux, then OpenBSD, then FreeBSD and finally Mint as well as Ubuntu14 as well as Sparky Linux. Maybe also a bit about my trials with GhostBSD. Why am I using more than 1? Mint 19.3 is the workhorse, Sparky does movies using conventional openshot as well as avidemux and Ubuntu 14 supports USB-tethering out of the box. USB-tethering is way faster than the alternatives and also very secure (as long as no-one nicks your phone). Tom Butz.

Google Play has been spreading advanced Android malware for years
by Peter Reutemann 01 May '20

01 May '20

'Hackers have been using Google Play for years to distribute an unusually advanced backdoor capable of stealing a wide range of sensitive data, researchers said on Tuesday. Researchers from security firm Kaspersky Lab have recovered at least eight Google Play apps that date back to 2018, a Kaspersky Lab representative said, but based on archive searches and other methods, the researchers believe malicious apps from the same advanced group seeded Google’s official market since at least 2016. Google removed recent versions of the malware shortly after the researchers from Kaspersky, and earlier fellow security firm Dr. Web, reported them. Apps from earlier were already removed, and it’s not clear what prompted the move. Third-party markets have also hosted the backdoored apps, and many of them remain available. Command-and-control domains were registered as early as 2015, raising the possibility the operation goes back earlier than 2016. Code in the malware and command servers it connects to contain several overlaps with a known hacking group dubbed OceanLotus (aka APT32, APT-C-00, and SeaLotus), leading researchers to believe the apps are the work of that advanced group.' -- source: https://arstechnica.com/information-technology/2020/04/sophisticated-androi… 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/

'Fairphone, the European manufacturer of mobile phones with a reduced environmental impact, has announced a partnership to offer /e/OS, the most "de-Googled" and pro-privacy Android OS, on their latest model Fairphone 3. An interesting move that reminds me of the recent introduction of the Google-free Huawei Mate 30. A pithy explainer of its "privacy by design ecosystem" -- and the point of "Android without Google" -- further notes: "We have removed many pieces of code that send your personal data to remote servers without your consent. We don't scan your data in your phone or in your cloud space, and we don't track your location a hundred times a day or collect what you're doing with your apps." According to TechCrunch, the e/OS variant of the Firephone 3 ships from May 6, priced at just under 480 euros -- "a 30 euro premium on the Googley flavor of Android you get on the standard Fairphone 3." The report adds that existing owners of the Fairphone 3 can manually install /e/OS gratis via an installer on its website.' -- source: https://mobile.slashdot.org/story/20/04/29/2131230 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/

Someone told me that I just needed to change the startup and it will fix the problem! All I need is for you to tell me the command. Tech support:: 10 minutes later, the User is still adamant that he is right. The tech is frustrated and fed up. Tech support:: (hush hush) Tech: Sorry, Sir. We don’t normally tell our customers this, but there is an undocumented DOS command that will fix the problem. User: I knew it! Tech : Just add the line LOAD NOSMOKE.COM at the end of the CONFIG.SYS. Let me know how it goes. 10 minutes later. User : It didn’t work. The power supply is still smoking. Tech : Well, what version of DOS are you using? User : MS-DOS 6.22 . Tech : That’s your problem there. That version of DOS didn’t come with NOSMOKE. Contact Microsoft and ask them for a patch that will give you the file. Let me know how it goes. 1 hour later. User : I need a new power supply. Tech support : How did you come to that conclusion? Tech support : (hush hush) User : Well, I rang Microsoft and told him about what you said, and he started asking questions about the make of power supply. Tech: Then what did he say? User: He told me that my power supply isn’t compatible with NOSMOKE. Cheers John..

OS Vulnerabilities
by Lawrence D'Oliveiro 29 Apr '20

29 Apr '20

While fixes for security bugs on the Linux platform usually come out quickly, there do seem to be a lot of laggards in deploying them <https://www.theregister.co.uk/2020/04/28/vulnerabilities_report_9_million/>. Why is this? The researchers speculate that "Windows admins are more accustomed to regular reboots after decades of conditioning," while "tooling for managing Linux fleets at scale generally lags behind that of Windows." Also perhaps the Linux installations include a lot of embedded/IoT devices that never get manufacturer updates.

Alternatives To The OOM Killer
by Lawrence D'Oliveiro 29 Apr '20

29 Apr '20

By default, if a process asks for more (virtual) memory, the Linux kernel never says no. (It can be easily configured to do so, if you want.) Therefore, it is possible for a process to try to access more memory than the system has available. This situation triggers the dreaded “OOM Killer” <https://lwn.net/Articles/317814/>, which hunts around for resource-hogging processes and kills them according to a priority scheme that nobody quite understands. To avoid things getting this bad, various people have come up with alternatives in the form of userspace daemons that monitor system resource usage, and implement their own (configurable) rules for killing processes before things get dire enough to wake up the OOM Killer. The announcement of Fedora 32 mentions <https://www.theregister.co.uk/2020/04/28/red_hat_summit/> the inclusion of one of these solutions, “EarlyOOM”. Looking at the project’s <https://github.com/rfjakob/earlyoom> readme page shows mention of two others: “nohang” (written in Python) and “oomd” (from Facebook). I see all three available as standard Debian packages, at least as of Debian Unstable.

Two spaces after a full stop was long-standing practice for typewritten text, and carried over to some extent to computer users. But with the advent of WYSIWYG word processing and proportional fonts, it became more common to adopt the practice of typeset text, and only put one space after a full stop, before the next sentence. Where do you stand? Microsoft ran a poll on the question, and it seems the majority favoured a single space.

Lenovo is joining Dell in the “OEM Linux Laptop” club
by Peter Reutemann 28 Apr '20

28 Apr '20

'It looks like Lenovo may upstage Dell as the big name in OEM Linux laptops—not counting specialty retailers like System76, of course. Red Hat and Lenovo are announcing pre-installed and factory-supported Fedora Workstation on several models of ThinkPad laptops at Red Hat Summit this week. Dell's Linux support has generally been limited to one or two very specific laptops—first, the old Atom-powered netbooks and, more recently, the XPS 13 Developer Edition line. Lenovo is planning a significantly broader Linux footprint in its lineup. Fedora Workstation will be a selectable option during purchase for the Thinkpad P1 Gen2, Thinkpad P53, and Thinkpad X1 Gen8 laptops—and Lenovo may offer even broader model support in the future. Lenovo Senior Linux Developer Mark Pearson, who will be the featured guest in the May 2020 Fedora Council Video Meeting, expresses the company's stance on forthcoming integration: "Lenovo is excited to become a part of the Fedora community. We want to ensure an optimal Linux experience on our products. We are committed to working with and learning from the open source community."' -- source: https://arstechnica.com/gadgets/2020/04/lenovo-is-joining-dell-in-the-oem-l… 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/

Hackers Are Exploiting a Sophos Firewall Zero-day
by Peter Reutemann 28 Apr '20

28 Apr '20

'Cyber-security firm Sophos has published an emergency security update to patch a zero-day vulnerability in its XG enterprise firewall product that was being abused in the wild by hackers. From a report: Sophos said it first learned of the zero-day on late Wednesday, April 22, after it received a report from one of its customers. The customer reported seeing "a suspicious field value visible in the management interface." After investigating the report, Sophos determined this was an active attack and not an error in its product. "The attack used a previously unknown SQL injection vulnerability to gain access to exposed XG devices," Sophos said in a security advisory today. Hackers targeted Sophos XG Firewall devices that had their administration (HTTPS service) or the User Portal control panel exposed on the internet. Sophos said the hackers used the SQL injection vulnerability to download a payload on the device. This payload then stole files from the XG Firewall.' -- source: https://tech.slashdot.org/story/20/04/27/162211 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 CPU Performance Testing Concludes AMD Beats Intel
by Peter Reutemann 27 Apr '20

27 Apr '20

'If you're looking for the best gaming CPU or the best CPU for desktop applications, there are only two choices to pick from: AMD and Intel. That fact has spawned an almost religious following for both camps, and the resulting flamewars, that make it tricky to get unbiased advice about the best choice for your next processor. But in many cases, the answer is actually very clear. In fact, for most users, it's a blowout win in AMD's favor. That's an amazing reversal of fortunes for the chipmaker after it teetered on the edge of bankruptcy a mere three years ago, making its turnaround all the more impressive as it continues to upset the entrenched Intel that enjoyed a decade of dominance... Pricing is the most important consideration for almost everyone, and AMD is hard to beat in the value department. The company offers a plethora of advantages, like bundled coolers and full overclockability on all models, not to mention complimentary software that includes the innovative Precision Boost Overdrive auto-overclocking feature. You also benefit from the broad compatibility of Socket AM4 motherboards that support both forward and backward compatibility, ensuring that not only do you get the most bang for your processor buck, but also your motherboard investment. AMD also allows overclocking on all but its A-Series motherboards (see our article on how to overclock AMD Ryzen), which is another boon for users. And, in this battle of AMD vs Intel CPUs, we haven't even discussed the actual silicon yet. AMD's modern processors tend to offer either more cores or threads and faster PCIe 4.0 connectivity at every single price point. "We're not covering laptop or server chips," the article notes, adding "There's a clear winner overall, but which brand of CPU you should buy depends most on what kind of features, price and performance are important to you." Still, it's noteworthy that AMD beats Intel in 7 out of 10 comparisons. The three in which Intel won were gaming performance ("only because we measure strictly by the absolute top performance possible"), drivers and software ("the company has an army of software developers [and] a decade of dominance also finds most software developers optimizing almost exclusively for Intel architectures"), and overclocking, where Intel "has far more headroom and much higher attainable frequencies. "Just be prepared to pay for the privilege."' -- source: https://slashdot.org/story/20/04/26/1622236 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/

Virtual meetings?
by Peter Reutemann 24 Apr '20

24 Apr '20

Hi everyone Our last meeting moved to virtual Google Hangout on short notice, which probably explained the low turnout. My question is, whether speakers and attendees would be willing to move to virtual ones, to keep our little community together and going? The last meeting was done with Google Hangouts, as it allows sharing the screen as well. Doesn't have to be Hangouts, it was simply convenient as a lot of people have gmail accounts. Open to viable alternatives. Stay safe!

When in Doubt: Hang Up, Look Up, and Call Back
by Peter Reutemann 24 Apr '20

24 Apr '20

'Many security-conscious people probably think they'd never fall for a phone-based phishing scam. But if your response to such a scam involves anything other than hanging up and calling back the entity that claims to be calling, you may be in for a rude awakening. Brian Krebs: Here's how one security and tech-savvy reader got taken for more than $10,000 in an elaborate, weeks-long ruse. Today's lesson in how not to get scammed comes from "Mitch," the pseudonym I picked for a reader in California who shared his harrowing tale on condition of anonymity. Mitch is a veteran of the tech industry -- having worked in security for several years at a fairly major cloud-based service -- so he's understandably embarrassed that he got taken in by this confidence scheme. On Friday, April 17, Mitch received a call from what he thought was his financial institution, warning him that fraud had been detected on his account. Mitch said the caller ID for that incoming call displayed the same phone number that was printed on the back of his debit card. But Mitch knew enough of scams to understand that fraudsters can and often do spoof phone numbers. So while still on the phone with the caller, he quickly logged into his account and saw that there were indeed multiple unauthorized transactions going back several weeks. Most were relatively small charges -- under $100 apiece -- but there were also two very recent $800 ATM withdrawals from cash machines in Florida. If the caller had been a fraudster, he reasoned at the time, they would have asked for personal information. But the nice lady on the phone didn't ask Mitch for any personal details. Instead, she calmly assured him the bank would reverse the fraudulent charges and said they'd be sending him a new debit card via express mail. After making sure the representative knew which transactions were not his, Mitch thanked the woman for notifying him, and hung up. The following day, Mitch received another call about suspected fraud on his bank account. Something about that conversation didn't seem right, and so Mitch decided to use another phone to place a call to his bank's customer service department -- while keeping the first caller on hold. "When the representative finally answered my call, I asked them to confirm that I was on the phone with them on the other line in the call they initiated toward me, and so the rep somehow checked and saw that there was another active call with Mitch," he said. "But as it turned out, that other call was the attackers also talking to my bank pretending to be me."' -- source: https://it.slashdot.org/story/20/04/23/1933254 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/

NordVPN Unveils First Mainstream WireGuard Virtual Private Network
by Peter Reutemann 23 Apr '20

23 Apr '20

'One of the largest VPN companies, NordVPN, is rolling out NordLynx -- it's first mainstream WireGuard virtual private network for its Windows, Mac, Android and iOS client-software applications. ZDNet reports: NordVPN's own tests have shown NordLynx easily outperforms the other protocols, IKEv2/IPsec and OpenVPN. How much faster? According to NordVPN's 256,886 speed tests, "When a user connects to a nearby VPN server and downloads content that's served from a content delivery network (CDN) within a few thousand miles/kilometers, they can expect up to twice higher download and upload speed." While speed is what customers will notice, security experts like WireGuard for its code's simplicity. With only about 4,000 lines of code, WireGuard's code can be comprehensively reviewed by a single individual. Besides WireGuard, NordVPN adds in its double Network Address Translation (NAT) system to protect users' privacy. This enables users to establish a secure VPN connection while storing no identifiable user data on a server. You're assigned a dynamic local IP address that remains assigned only while the session is active. User authentication is done with the help of a secure external database. To switch to NordLynx, users need to update their NordVPN app to the latest version. The NordLynx protocol can be chosen manually from the Settings menu.

Stripe Is Silently Recording Your Movements On Its Customers' Websites
by Peter Reutemann 23 Apr '20

23 Apr '20

'Michael Lynch, blogger and former software engineer at Microsoft and Google, discovered that the payment processing platform Stripe and its official JavaScript library records all browsing activity on its customers' websites and reports it back to the company. Lynch says this data includes the following: 1. Every URL the user visits on my site, including pages that never display Stripe payment forms 2. Telemetry about how the user moves their mouse cursor while browsing my site 3. Unique identifiers that allow Stripe to correlate visitors to my site against other sites that accept payment via Stripe In his blog post, Lynch shares what he found, who else it affects, and how you can limit Stripe's data collection in your web applications. Here's how he says he made the discovery: I discovered this by accident while adding paid plans to my portfolio rebalancer. As part of development, I was using an HTTP proxy that allows me to inspect HTTP traffic from my browser. After successfully implementing my app's payment flow with Stripe, I noticed that every page navigation generated a new HTTP POST request to a Stripe URL. This was strange because none of the pages I visited contained any calls to Stripe's library. In fact, my app doesn't collect payment information from users until they create an account, but Stripe was making HTTP requests when I landed on my app's homepage as a brand new user with no cookies or stored credentials. "I looked around for an official disclosure from Stripe about this behavior, but I couldn't find anything," adds Lynch. "The closest I found is this vague paragraph on their npm package description, which the Stripe support rep quoted to me: 'To best leverage Stripe's advanced fraud functionality, ensure that Stripe.js is loaded on every page, not just your checkout page. This allows Stripe to detect anomalous behavior that may be indicative of fraud as customers browse your website.'" "The privacy policy is a bit more specific about the data they collect, but it implies that they're collecting this data on stripe.com rather than on customer sites," writes Lynch. "Worryingly, the privacy policy also includes loose wording that allows Stripe to sell this data to advertisers: 'When you visit our Sites or online services, both we and certain third parties collect information about your online activities over time and across different sites to provide you with advertising about products and services tailored to your individual interests.'"' -- source: https://yro.slashdot.org/story/20/04/22/0023222 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/

Vivaldi Browser Gets Built-in Tracking Blocker, Goes GA on Android
by Peter Reutemann 23 Apr '20

23 Apr '20

'Vivaldi, the browser launched by former Opera CEO Jon von Tetzchner, has long positioned itself as a highly customizable alternative to Chrome and Firefox for power users. Today, the team is launching version 3.0 of its desktop browser, with built-in tracker and ad blockers, and it's bringing its Android browser out of beta. From a report: I've long been a fan of Vivaldi, but the company was relatively late to the tracking protection game. Now it's doubling down by integrating a blocklist powered by DuckDuckGo's Tracker Radar. Like competing browsers, Vivaldi offers three blocking levels that users can easily toggle on and off for individual websites. Those blocking levels are relatively blunt, though, with the options to either block trackers, block trackers and ads, or disable blocking. Competitors like Edge offer slightly more nuanced options for blocking trackers, though I would expect Vivaldi to adopt a similar scheme over time.' -- source: https://slashdot.org/story/20/04/22/1550251 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/

Edge TV Now Online-Only
by Lawrence D'Oliveiro 22 Apr '20

22 Apr '20

If there is anybody else besides me who wondered what happened to Edge TV, as of the beginning of this month it is no longer on Freeview, it can now only be viewed as an online stream <https://www.stuff.co.nz/entertainment/tv-radio/113928839/the-edge-tv-remove…>. In the last few days of June, there was a promo announcing that it was going HD, but I don’t recall it mentioning that it was leaving the broadcast airwaves. Quote: MediaWorks chief executive Michael Anderson says the move is in line with audience trends, which show people primarily consume music videos online. While that may be mostly true, personally I would go look for videos on YouTube after seeing them first on Edge TV.

Discord Switching From Go To Rust
by Lawrence D'Oliveiro 22 Apr '20

22 Apr '20

Came across this blog post <https://blog.discordapp.com/why-discord-is-switching-from-go-to-rust-a190bb…> explaining why Discord, which has been using Google’s Go language to implement its services, has now decided to rewrite them in Mozilla’s Rust. The problem was garbage collection. Go has a similar memory-allocation model to Java or LISP, where you can create objects and simply forget about them when you don’t need them any more, and a background process will automatically reclaim the storage at some point. The trouble is, that reclamation process (the “garbage collector”) tends to be the source of performance bottlenecks in the system. Not to mention that the memory usage of your program can grow to fill all available space, unless you impose arbitrary limits on it. Languages like Perl and Python use a hybrid model, where objects have reference counts attached to them, keeping track of how many other objects or variables still point to them, so they can be automatically freed when the count goes to zero. There are cases where this isn’t enough, and in those cases a full garbage-collection process kicks in. One benefit that I certainly observe with this is that memory usage for a program can remain reasonable, even after it has been running for a long time. Rust avoids the whole issue in a clever way, by having the compiler enforce memory-ownership restrictions in the language itself, so memory can be correctly allocated and freed without resorting to a garbage collector. The result is that Rust can achieve significantly higher performance than Go, while avoiding most of the attendant risks of dumping the whole responsibility for memory management on the programmer, as is done in languages like C++ and C.

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

'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.

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."

Guess how much it costs to get the castor wheel kit for your new Apple Mac Pro <https://www.theregister.co.uk/2020/04/16/apple_mac_pro_699_dollar_wheels/>. I wonder what other furnishing-related items Apple could sell. How about a nice doily to go on top?

New Jersey Needs COBOL Programmers!
by Lawrence D'Oliveiro 17 Apr '20

17 Apr '20

The Governor of the US state of New Jersey is appealing for help in maintaining their elderly COBOL-based mainframe systems <https://www.theregister.co.uk/2020/04/05/new_jersey_seeks_cobol_volunteers/> that process welfare benefit requests. The volume of requests has gone up a lot lately, and the systems are having trouble coping. By the way, I don’t understand this “ugly side of technical debt” phrase. Does technical debt have a pretty side?

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/
