A German State is Switching Its 25,000 Computers From Windows to Linux
by Peter Reutemann 22 Nov '21

22 Nov '21

'The north-German state of Schleswig-Holstein plans to switch to open source software..." reports Mike Saunders from LibreOffice. "By the end of 2026, Microsoft Office is to be replaced by LibreOffice on all 25,000 computers used by civil servants and employees (including teachers), and the Windows operating system is to be replaced by GNU/Linux." The tech site Foss Force writes: This seems to be a done deal, as the steps for the transition from proprietary to open have already been codified by the Schleswig-Holstein state parliament, and explained in plain language in an interview with Jan Philipp Albrecht, the state's digital minister, that was published in c't, a German language computer magazine (Google Translate version here). In the interview, Albrecht said that part of the transition to open source is already in the works, and pointed out that 90% of state administration conferencing is conducted using the open source video conferencing platform Jitsi. "We have been testing LibreOffice in our IT department for two years, and our experience is clear: it works," he said. "This also applies, for example, when editing Microsoft Word documents with comments... No Linux distribution has been chosen yet to use as a standard, although Albrecht said they're currently looking at five distributions that suit their purposes.' -- source: https://linux.slashdot.org/story/21/11/21/0231218 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Thousands of Firefox Users Accidentally Commit Login Cookies On GitHub
by Peter Reutemann 19 Nov '21

19 Nov '21

'Thousands of Firefox cookie databases containing sensitive data are available on request from GitHub repositories, data potentially usable for hijacking authenticated sessions. The Register reports: These cookies.sqlite databases normally reside in the Firefox profiles folder. They're used to store cookies between browsing sessions. And they're findable by searching GitHub with specific query parameters, what's known as a search "dork." Aidan Marlin, a security engineer at London-based rail travel service Trainline, alerted The Register to the public availability of these files after reporting his findings through HackerOne and being told by a GitHub representative that "credentials exposed by our users are not in scope for our Bug Bounty program." Marlin then asked whether he could make his findings public and was told he's free to do so. "I'm frustrated that GitHub isn't taking its users' security and privacy seriously," Marlin told The Register in an email. "The least it could do is prevent results coming up for this GitHub dork. If the individuals who uploaded these cookie databases were made aware of what they'd done, they'd s*** their pants." Marlin acknowledges that affected GitHub users deserve some blame for failing to prevent their cookies.sqlite databases from being included when they committed code and pushed it to their public repositories. "But there are nearly 4.5k hits for this dork, so I think GitHub has a duty of care as well," he said, adding that he's alerted the UK Information Commissioner's Office because personal information is at stake. Marlin speculates that the oversight is a consequence of committing code from one's Linux home directory. "I imagine in most of the cases, the individuals aren't aware that they've uploaded their cookie databases," he explained. "A common reason users do this is for a common environment across multiple machines."' -- source: https://news.slashdot.org/story/21/11/18/2227206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Has a Serious Security Problem That Once Again Enables DNS Cache Poisoning
by Peter Reutemann 18 Nov '21

18 Nov '21

'As much as 38 percent of the Internet's domain name lookup servers are vulnerable to a new attack that allows hackers to send victims to maliciously spoofed addresses masquerading as legitimate domains, like bankofamerica.com or gmail.com. The exploit, unveiled in research presented today, revives the DNS cache-poisoning attack that researcher Dan Kaminsky disclosed in 2008. He showed that, by masquerading as an authoritative DNS server and using it to flood a DNS resolver with fake lookup results for a trusted domain, an attacker could poison the resolver cache with the spoofed IP address. >From then on, anyone relying on the same resolver would be diverted to the same imposter site. The sleight of hand worked because DNS at the time relied on a transaction ID to prove the IP number returned came from an authoritative server rather than an imposter server attempting to send people to a malicious site. The transaction number had only 16 bits, which meant that there were only 65,536 possible transaction IDs. Kaminsky realized that hackers could exploit the lack of entropy by bombarding a DNS resolver with off-path responses that included each possible ID. Once the resolver received a response with the correct ID, the server would accept the malicious IP and store the result in cache so that everyone else using the same resolver -- which typically belongs to a corporation, organization, or ISP -- would also be sent to the same malicious server.' -- source: https://linux.slashdot.org/story/21/11/17/1856235 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Latency Numbers Every Programmer Should Know
by Lawrence D'Oliveiro 17 Nov '21

17 Nov '21

Somebody did a nice chart a while back <https://gist.github.com/hellerbarde/2843375> of the time it takes to perform many common data transfer operations on contemporary hardware. And note the multi-part figure, where the basic unit in each block is a bit more than an order of magnitude greater than the one in the previous block. And if the figure isn’t dramatic enough, a commenter has said “let’s multiply all the numbers by a billion” (just to bring them into more human-comprehensible scales), and then liken them to common things that people do, from making a cup of coffee, all the way up to completing a bachelor’s degree.

Scientists Send Data Using Nuclear Radiation
by Lawrence D'Oliveiro 16 Nov '21

16 Nov '21

A research group has used fast neutrons <https://www.theregister.com/2021/11/15/wireless_information_transfer_with_f…> as a communication channel, to send legible data between a transmitter and a receiver. Their proof of concept is very low-bandwidth and requires a lot of complicated equipment, but at least it does show (safety issues aside) that it is theoretically possible. The issue with high-energy subatomic particles is, how do you turn them on and off at will -- i.e. modulate the intensity of the beam to convey information? This group used some kind of shutter system (“neutron chopper”) in conjunction with some quantity of radioactive californium-252 as their neutron source. But they mention that someone else has come up with a device that is basically a particle accelerator on a chip, able to produce a stream of neutrons from non-radioactive starting components on demand.

Microsoft Fixes An Issue
by Lawrence D'Oliveiro 16 Nov '21

16 Nov '21

The latest Windows 11 update <https://www.theregister.com/2021/11/15/windows_11_insiders_bug_fixes/> gets ever closer to perfection. I like this one: We fixed an issue that prevents your device from starting up, and it becomes unresponsive because of licensing API calls. Because what would that good old “enrichment of the user experience” be like without licensing API calls ... The writer’s verdict on the new OS sounds more like damning with faint praise: We have been running Windows 11 for daily work since official release and are happy to report that it is usable and stable in our experience so far, though useful improvements over its predecessor are hard to identify.

DDR4 memory protections are broken wide open by new Rowhammer technique
by Peter Reutemann 16 Nov '21

16 Nov '21

'Rowhammer exploits that allow unprivileged attackers to change or corrupt data stored in vulnerable memory chips are now possible on virtually all DDR4 modules due to a new approach that neuters defenses chip manufacturers added to make their wares more resistant to such attacks. Rowhammer attacks work by accessing—or hammering—physical rows inside vulnerable chips millions of times per second in ways that cause bits in neighboring rows to flip, meaning 1s turn to 0s and vice versa. Researchers have shown the attacks can be used to give untrusted applications nearly unfettered system privileges, bypass security sandboxes designed to keep malicious code from accessing sensitive operating system resources, and root or infect Android devices, among other things. All previous Rowhammer attacks have hammered rows with uniform patterns, such as single-sided, double-sided, or n-sided. In all three cases, these “aggressor” rows—meaning those that cause bitflips in nearby “victim” rows—are accessed the same number of times. Research published on Monday presented a new Rowhammer technique. It uses non-uniform patterns that access two or more aggressor rows with different frequencies. The result: all 40 of the randomly selected DIMMs in a test pool experienced bitflips, up from 13 out of 42 chips tested in previous work from the same researchers.' -- source: https://arstechnica.com/gadgets/2021/11/ddr4-memory-is-even-more-susceptibl… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Ask Slashdot: Why Is Firefox Losing Users?
by Peter Reutemann 05 Nov '21

05 Nov '21

'This weekend finds some long-time Slashdot readers debating why research shows Firefox losing market share. Long-time Slashdot reader chiguy shares one theory: "Firefox keeps losing users, according to this rant, because it arrogantly refuses to listen to its users." Slashdot reader BAReFO0t countered that that can't be the reason, "because Google does that too." (They blame Chrome's "feature" addition treadmill, where "they keep adding stupid kitchen sinks for the sole and only purpose to make others unable to keep up.") Long-time Slashdot reader Z00L00K thinks that "All those totally unnecessary UI changes are what REALLY annoys users. Not only the immediately visible things in the header but also the renaming of items in the menus just bugs people." But long-time Slashdot reader AmiMoJo argues that "the most popular browser, Chrome, has all those things. In fact all the browsers that are more popular than Firefox do, so the idea that those are unpopular and driving people away doesn't really hold up... Firefox's decline is mostly due to Chrome just being really good, and [Firefox] not having a decent mobile version." I'm still a loyal Firefox user. (Although the thing that annoyed me was when Firefox suddenly changed the keyboard shortcut for copying a link from CNTRL-A to CNTRL-L.) The "rant" at ItsFoss argues that Firefox's original sin was in 2009 when it decided to move tabs to the top of the browser, and when favorite features could no longer be re-enabled in Firefox's about:config file. But that's what I like about Firefox -- at it's best, it's ultimately customizable, with any feature you want easily enabled in what's essentially an incredibly detailed "preferences" menu. Maybe other browsers are just better at attracting new users through purely mechanical advantages like default placement on popular systems? Long-time Slashdot reader zenlessyank is also a long-time Firefox user -- "Been using it since Netscape" -- and countered all the doubters with a comment headlined "Firefox rocks!" "Doesn't matter to me how many other users there are or aren't I will still use it as long as it stays updated." But what are your thoughts? Feel free to share your own opinions and experiences with Firefox in the comments.' -- source: https://news.slashdot.org/story/21/09/12/181257 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Booming Underground Market for Bots That Steal Your 2FA Codes
by Peter Reutemann 04 Nov '21

04 Nov '21

'The bots convincingly and effortlessly help hackers break into Coinbase, Amazon, PayPal, and bank accounts. From a report: The call came from PayPal's fraud prevention system. Someone had tried to use my PayPal account to spend $58.82, according to the automated voice on the line. PayPal needed to verify my identity to block the transfer. "In order to secure your account, please enter the code we have sent your mobile device now," the voice said. PayPal sometimes texts users a code in order to protect their account. After entering a string of six digits, the voice said, "Thank you, your account has been secured and this request has been blocked. Don't worry if any payment has been charged to your account: we will refund it within 24 to 48 hours. Your reference ID is 1549926. You may now hang up," the voice said. But this call was actually from a hacker. The fraudster used a type of bot that drastically streamlines the process for hackers to trick victims into giving up their multi-factor authentication codes or one-time passwords (OTPs) for all sorts of services, letting them log in or authorize cash transfers. Various bots target Apple Pay, PayPal, Amazon, Coinbase, and a wide range of specific banks. Whereas fooling victims into handing over a login or verification code previously would often involve the hacker directly conversely with the victim, perhaps pretending to be the victim's bank in a phone call, these increasingly traded bots dramatically lower the barrier of entry for bypassing multi-factor authentication.' -- source: https://yro.slashdot.org/story/21/11/03/1842245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Trojan Source' Bug Threatens the Security of All Code
by Peter Reutemann 02 Nov '21

02 Nov '21

'"Virtually all compilers -- programs that transform human-readable source code into computer-executable machine code -- are vulnerable to an insidious attack in which an adversary can introduce targeted vulnerabilities into any software without being detected," warns cybersecurity expert Brian Krebs in a new report. An anonymous reader shares an excerpt: Researchers with the University of Cambridge discovered a bug that affects most computer code compilers and many software development environments. At issue is a component of the digital text encoding standard Unicode, which allows computers to exchange information regardless of the language used. Unicode currently defines more than 143,000 characters across 154 different language scripts (in addition to many non-script character sets, such as emojis). Specifically, the weakness involves Unicode's bi-directional or "Bidi" algorithm, which handles displaying text that includes mixed scripts with different display orders, such as Arabic -- which is read right to left -- and English (left to right). But computer systems need to have a deterministic way of resolving conflicting directionality in text. Enter the "Bidi override," which can be used to make left-to-right text read right-to-left, and vice versa. "In some scenarios, the default ordering set by the Bidi Algorithm may not be sufficient," the Cambridge researchers wrote. "For these cases, Bidi override control characters enable switching the display ordering of groups of characters." Bidi overrides enable even single-script characters to be displayed in an order different from their logical encoding. As the researchers point out, this fact has previously been exploited to disguise the file extensions of malware disseminated via email. Here's the problem: Most programming languages let you put these Bidi overrides in comments and strings. This is bad because most programming languages allow comments within which all text -- including control characters -- is ignored by compilers and interpreters. Also, it's bad because most programming languages allow string literals that may contain arbitrary characters, including control characters. "So you can use them in source code that appears innocuous to a human reviewer [that] can actually do something nasty," said Ross Anderson, a professor of computer security at Cambridge and co-author of the research. "That's bad news for projects like Linux and Webkit that accept contributions from random people, subject them to manual review, then incorporate them into critical code. This vulnerability is, as far as I know, the first one to affect almost everything." The research paper, which dubbed the vulnerability "Trojan Source," notes that while both comments and strings will have syntax-specific semantics indicating their start and end, these bounds are not respected by Bidi overrides. [...] Anderson said such an attack could be challenging for a human code reviewer to detect, as the rendered source code looks perfectly acceptable. "If the change in logic is subtle enough to go undetected in subsequent testing, an adversary could introduce targeted vulnerabilities without being detected," he said. Equally concerning is that Bidi override characters persist through the copy-and-paste functions on most modern browsers, editors, and operating systems.' -- source: https://it.slashdot.org/story/21/11/01/2147254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Raspberry Pi Zero 2 W: 5x faster than the original for $5 more
by Peter Reutemann 01 Nov '21

01 Nov '21

'The diminutive Raspberry Pi Zero is getting its first upgrade in nearly five years. Today, Raspberry Pi founder Eben Upton announced the Raspberry Pi Zero 2 W, a new $15 product that puts the processor from the Raspberry Pi 3 into a board the exact same size as the original Zero. The new board swaps the old Zero's 1 GHz single-core ARM11 processor for a quad-core Cortex A53-based Broadcom BCM2710A1 processor, also clocked at 1 GHz—the same processor used in the original Raspberry Pi 3 released back in 2016, albeit clocked slightly lower. This is a substantial increase in power and capability for the Pi Zero, going from one core to four and from 32 bits to 64. Upton said that the performance increase over the original Zero "varies across workloads" but that for multithreaded tasks like those simulated by sysbench, "it is almost exactly five times faster." Heat dissipation is provided by "thick internal copper layers" in the board, which should help prevent thermal throttling without the use of additional fans or heatsinks.' -- source: https://arstechnica.com/gadgets/2021/10/raspberry-pi-zero-2-w-crams-pi-3-pa… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Newly-Discovered 'AbstractEmu' Malware Rooted Android Devices, Evaded Detection
by Peter Reutemann 01 Nov '21

01 Nov '21

'"New Android malware can root infected devices to take complete control and silently tweak system settings, as well as evade detection using code abstraction and anti-emulation checks," reports BleepingComputer. Cybersecurity company Lookout said on its blog that they'd spotted the malware on Google Play "and prominent third-party stores such as the Amazon Appstore and the Samsung Galaxy Store.... To protect Android users, Google promptly removed the app as soon as we notified them of the malware." We named the malware "AbstractEmu" after its use of code abstraction and anti-emulation checks to avoid running while under analysis. A total of 19 related applications were uncovered, seven of which contain rooting functionality, including one on Play that had more than 10,000 downloads... This is a significant discovery because widely-distributed malware with root capabilities have become rare over the past five years. As the Android ecosystem matures there are fewer exploits that affect a large number of devices, making them less useful for threat actors... By using the rooting process to gain privileged access to the Android operating system, the threat actor can silently grant themselves dangerous permissions or install additional malware — steps that would normally require user interaction. Elevated privileges also give the malware access to other apps' sensitive data, something not possible under normal circumstances... AbstractEmu does not have any sophisticated zero-click remote exploit functionality used in advanced APT-style threats, it is activated simply by the user having opened the app. As the malware is disguised as functional apps, most users will likely interact with them shortly after downloading... By rooting the device, the malware is able to silently modify the device in ways that would otherwise require user interaction and access data of other apps on the device. "Apps bundling the malware included password managers and tools like data savers and app launchers," reports BleepingComputer, "all of them providing the functionality they promised to avoid raising suspicions..." Lookout's blog post said they'd spotted people affected by the malware in 17 different countries.' -- source: https://it.slashdot.org/story/21/10/31/1253225 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Protonmail Celebrates Swiss Court Victory Exempting it From Telco Data Retention Laws
by Peter Reutemann 28 Oct '21

28 Oct '21

'Encrypted email provider Protonmail has hailed a recent Swiss legal ruling as a "victory for privacy," after winning a lawsuit that sees it exempted from data retention laws in the mountainous realm. From a report: Referring to a previous ruling that exempted instant messaging services from data capture and storage laws, the Protonmail team said this week: "Together, these two rulings are a victory for privacy in Switzerland as many Swiss companies are now exempted from handing over certain user information in response to Swiss legal orders." Switzerland's Federal Administrative Court ruled on October 22 that email providers in Switzerland are not considered telecommunications providers under Swiss law, thereby removing them from the scope of data retention requirements imposed on telcos. The victory comes after controversy over a previous (and not directly related) Swiss court order that forced the company to collect mobile device push notification identifiers from a specified user's account. That user was later arrested by French police, who had asked their Swiss counterparts to obtain the surveillance order. Protonmail chief exec Andy Yen told The Register his business doesn't routinely collect such data on its users.' -- source: https://yro.slashdot.org/story/21/10/27/147224 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Core i9 11900K: Five Linux Distros Show Sizable Lead Over Windows 11
by Peter Reutemann 28 Oct '21

28 Oct '21

'Phoronix: Now that Windows 11 has been out as stable and the initial round of updates coming out, I've been running fresh Windows 11 vs. Linux benchmarks for seeing how Microsoft's latest operating system release compares to the fresh batch of Linux distributions. First up is the fresh look at the Windows 11 vs. Linux performance on an Intel Core i9 11900K Rocket Lake system. Microsoft Windows 11 Pro with all stable updates as of 18 October was used for this round of benchmarking on Intel Rocket Lake. The Windows 11 performance was being compared to all of the latest prominent Linux distributions, including: Ubuntu 20.04.3 LTS, Ubuntu 21.10, Arch Linux (latest rolling), Fedora Workstation 35, Clear Linux 35150. All the testing was done on the same Intel Core i9 11900K test system at stock speeds (any frequency differences reported in the system table come down to how the information is exposed by the OS, i.e. base or turbo reporting) with 2 x 16GB DDR4-3200 memory, 2TB Corsair Force MP600 NVMe solid-state drive, and an AMD Radeon VII graphics card. Each operating system was cleanly installed and then run at its OS default settings for seeing how the out-of-the-box OS performance compares for these five Linux distributions to Microsoft Windows 11 Pro. But for the TLDR version... Out of 44 tests run across all six operating systems, Windows 11 had just three wins on this Core i9 11900K system. Meanwhile Intel's own Clear Linux platform easily dominated with coming in first place 75% of the time followed by Fedora Workstation 35 in second place with first place finishes 9% of the time. The geometric mean for all 44 tests showed Linux clearly in front of Windows 11 for this current-generation Intel platform. Ubuntu / Arch / Fedora were about 11% faster overall than Windows 11 Pro on this system. Meanwhile, Clear Linux was about 18% faster than Windows 11 and enjoyed about 5% better performance overall than the other Linux distributions.' -- source: https://linux.slashdot.org/story/21/10/27/1625217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Setback for Nvidia's $54 Billion ARM Bid as EU Regulators Open Probe
by Peter Reutemann 28 Oct '21

28 Oct '21

'Nvidia suffered a setback on Wednesday as EU antitrust regulators opened a full-scale investigation into its $54 billion bid for British chip designer ARM on concerns the deal could lead to higher prices, less choice and reduced innovation. From a report: Britain's competition agency is also probing the deal for the country's most important technology company, warning that it could damage competition and weaken rivals. Reuters reported the European Commission viewed as insufficient concessions offered by the world's biggest maker of graphics and artificial intelligence (AI) chips during its preliminary review. Nvidia has not disclosed what these are but it has previously said it would maintain ARM as a neutral technology supplier to sooth concerns from customers such as Qualcomm, Samsung and Apple. The Commission said it would decide by March 15 whether to clear or block the deal. "Whilst Arm and Nvidia do not directly compete, Arm's IP is an important input in products competing with those of Nvidia, for example in datacentres, automotive and in Internet of Things," EU competition chief Margrethe Vestager said in a statement.' -- source: https://slashdot.org/story/21/10/27/1648229 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Android's 12L Feature Drop Aims To Be a Big Improvement for Folding Phones
by Peter Reutemann 28 Oct '21

28 Oct '21

'At this year's Android Dev Summit, Google announced an upcoming update for devices with larger screens, which includes tablets, foldables, and devices that run ChromeOS. From a report: Google is calling the update 12L, and it's supposed to make Android 12 run smoother on big screens. We first heard the possibility of a "12.1" update in late September, and it looks like many of the rumored features are true. 12L optimizes the layout of a device's UI, adjusting the placement of the home screen, lock screen, notifications, Quick Settings, and more. Google notes that any screen 600 density-independent pixels (dp) and above will display a two-column layout that makes use of the entire screen. In the example Google shows, the Quick Settings menu is pushed towards the left side of the screen, while the notifications panel is locked to the right, giving you the ability to access both simultaneously -- all without opening one app and closing another. 12L also introduces a new taskbar that makes it easier for users to quickly switch between different apps. Dragging and dropping an app from the taskbar opens it up in split-screen mode, which Google notes it has enabled for all apps, whether they're resizable or not.' -- source: https://tech.slashdot.org/story/21/10/27/1821200 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Trying To Cripple Its Own Open-Source Project
by Lawrence D'Oliveiro 23 Oct '21

23 Oct '21

Microsoft is trying to remove a feature called “Hot Reload” from Dotnet, saying it is something that should only be available through Visual Studio <https://www.theregister.com/2021/10/22/microsoft_net_hot_reload_visual_stud…>. Trouble is, this is the (supposedly) Open-Source version of Dotnet. And you do not take away useful features from Open-Source projects. You can do that to proprietary products, where the users have no choice but to put up with it. As of this writing, the commit that removes the feature has already been merged, but a follow up request to revert that change, while gathering a lot of support, has not been accepted into the official code base yet. As one of the commenters says: “This is the PR that is truly going to decide .NET is really an OSS or not!”. This is just one in a long line of incidents <https://www.theregister.com/2021/10/18/net_foundation_gnome/> casting doubt on the independence of Dotnet as an Open-Source project.

App Telemetry For Developers
by Lawrence D'Oliveiro 23 Oct '21

23 Oct '21

Here’s an interesting idea <https://www.theregister.com/2021/10/22/new_relic_codestream/>: if an app should crash during a production run, it can send telemetry data back to the developer providing some program state and pinpointing exact locations in the source code. This is done using eBPF (Extended Berkeley Packet Filter), which is able to collect information about running applications with minimal impact. You thought packet-filtering was only about managing network activity, but no, it is more useful than that. Yes, there is potential for this sort of thing to be misused, if it is not correctly managed. With great power comes great responsibility etc. By the way, while eBPF may have its roots in the older BPF as found in the BSDs, it is nevertheless a Linux-only technology <https://ebpf.io/>. Though Microsoft is trying to port some parts of it to Windows <https://cloudblogs.microsoft.com/opensource/2021/05/10/making-ebpf-work-on-…>.

GPSD Bug Will Switch Your Time-Keeping Systems To March 2002 This Weekend, Unless You Update
by Peter Reutemann 22 Oct '21

22 Oct '21

'"Apparently a bug in GPSD, the daemon responsible for deriving time from the GPS system, is going to trigger on October 24, 2021, jumping the time back to March of 2002," writes Slashdot reader suutar. "There's a fix that's been committed since August, but of course not everything is up to date." ZDNet's Steven J. Vaughan-Nichols writes: This will be ugly. Or, as Stephen Williams, who uncovered the bug put it, "I have a feeling that there will be some 'interesting moments' in the early morning when a bunch of the world's stratum 1 NTP servers using GPSD take the long strange trip back to 2002." GPSD maintainer Gary E. Miller has acknowledged the problem, and a fix has been made to the code. To be exact, the fix is in August 2021's GPSD 3.23 release. So, what's the problem if the fix is already in? Well, there are two problems. First, it won't be backported to previous releases. If you're still using an older version, you may be out of luck. Second, as Miller observed, not all distros "pick up GPSD updates or upstream their patches. [This] is a very sore spot with me." So, just because your operating system is up to date does not mean that it will have the necessary GPSD fix. Miller suggests that you check it and do it yourself: "I [am] gonna fall back on Greg K_H's dictum: All users must update." Oh, wondering what the mysterious root cause of all this commotion GPS Week Rollover? It's a legacy GPS problem. The GPS signal GPS week number uses a 10-bit code with a maximum value of 1,023. This means every 19.7 years; the GPS week number rolls over to zero. Or, as Miller noted, "This code is a 1024 week time warp waiting to happen." So, check your systems now for this problem. And, if, like most of us, you're relying on someone upstream from you for the correct time, check with them to make sure they've taken care of this forthcoming trouble.' -- source: https://it.slashdot.org/story/21/10/21/2053248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Versus The Chip Foundries
by Lawrence D'Oliveiro 21 Oct '21

21 Oct '21

Nice backgrounder <https://arstechnica.com/tech-policy/2021/10/intel-slipped-and-its-future-no…> on how Intel (and American chipmakers generally) slipped from their leadership position by overlooking an important new business: manufacturing chips according to other people’s designs. We’ve all heard of Taiwan-based TSMC, which is the world leader in this area; when it was founded way back in 1987 (with help from the Taiwanese Government and from Philips), none of the US companies would take such an idea seriously. They didn’t think it would amount to a very profitable business, and anyway they wanted to control their own Intellectual Property. Plus, a company that made chips both for its own internal businesses and for others could never be seen to be entirely above accusations of conflict of interest. Note also the role played by Carver Mead, basically the father of the whole concept of RISC. He wanted a place to go to, where his students (and those of other teachers) could get their designs turned into actual working chips. He had special personal connections with Intel to get access to their fabs, but he knew others were not so lucky. So he played an influential part in getting TSMC started.

Brave Removes Google as its Default Search Engine
by Peter Reutemann 20 Oct '21

20 Oct '21

'As Paul Thurrott reports, Brave is removing Google Search as its default search engine. From the report: Going forward, the Brave web browser will default to Brave Search. "Brave Search has grown significantly since its release last June, with nearly 80 million queries per month," Brave CEO and co-founder Brendan Eich says. "Our users are pleased with the comprehensive privacy solution that Brave Search provides against Big Tech by being integrated into our browser. As we know from experience in many browsers, the default setting is crucial for adoption, and Brave Search has reached the quality and critical mass needed to become our default search option, and to offer our users a seamless privacy-by-default online experience." Brave Search is built on top of an independent index, and doesn't track users, their searches, or their clicks, the firm says. And starting with Brave 1.3 on desktop and Android, and Brave 1.32 on iOS, it will be the default search engine in the browser, instead of Google, in the United States, Canada, and the United Kingdom. It is also replacing Qwant in France and DuckDuckGo in Germany, and Brave says that more locales will be added in the next several months. Existing users can keep their chosen search engine default, of course, and new users who prefer other search engines can configure as needed. Brave Search doesn't display ads today, but the free version of the service will soon be ad-supported. An ad-free Premium version is coming "in the near future," Brave says. Along with this search engine news, Brave announced the Web Discovery Project (WDP), "which it describes as a privacy-preserving system for users to anonymously contribute data to improve Brave Search results," writes Thurrott. "The WDP is an opt-in feature that protects user privacy and anonymity by ensuring that contributed data is not linked to individuals, their devices, or any set of users." It has a GitHub repo available to help you learn more about this system.' -- source: https://tech.slashdot.org/story/21/10/19/2121251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

PowerPC Fork of Firefox Reaches End of the Road
by Peter Reutemann 15 Oct '21

15 Oct '21

'Ars Technica: It has been well over a decade since PowerPC Macs roamed the earth -- so long that the Intel Macs that replaced them are themselves being replaced by something else. But to this day, there's a small community of people still developing software for PowerPC Macs and Mac OS 9. One of those projects was TenFourFox, a fork of the Firefox browser for G3, G4, and G5-based PowerPC Macs running Mac OS X 10.4 or 10.5. Maintained primarily by Cameron Kaiser, the TenFourFox project sprang up in late 2010 after Mozilla pulled PowerPC support from Firefox 4 during its development. And amazingly, the browser has continued to trundle on ever since. But continuing to backport Firefox features to aging, stuck-in-time PowerPC processors only got more difficult as time went on. And in March of this year, Kaiser announced that TenFourFox updates would be ending after over a decade of development. The final planned release of TenFourFox was earlier this month. Kaiser's full post is long, but it's worth a read for vintage-computer enthusiasts or anyone who works on software -- Kaiser expresses frustration with the realities of developing and supporting a niche app, but he also highlights TenFourFox's impressive technical achievements and ruminates on the nature of the modern Internet and open source software development [...]. Kaiser doesn't intend to fully halt work on the browser, but he is downshifting it into what he calls "hobby mode." He will continue to backport security patches from newer ESR releases of Firefox and post them to the TenFourFox Github page, but anyone who wants to use these will need to build the app themselves. Kaiser also won't commit to providing support for these additions or providing them on any kind of schedule. Other developers are also welcome to continue to release TenFourFox builds on their own.

'Framework, makers of the modular 13.5-inch Framework laptop that's designed to be easily repaired and upgraded, has launched a dedicated marketplace filled with replacement parts and upgrades for its portable computer. The Verge reports: Writing in a blog post, the company said the marketplace is currently focused on replacement parts and expansion cards, but that it hopes to add more customization modules like additional language keyboards later this year, as well as third-party and community developed modules in 2022. The marketplace already includes a range of expansion cards for the laptop, which are designed to slot into its four modular compartments to add everything from extra storage to features like MicroSD card slots or more USB ports. There's also user upgradeable RAM and storage for sale. But the store is clearly a work in progress, and lists a host of other items like replacement CPU-equipped mainboards, keyboards, and spare parts like batteries and displays as "coming soon."

LibreOffice, OpenOffice Bug Allows Hackers To Spoof Signed Docs
by Peter Reutemann 12 Oct '21

12 Oct '21

'LibreOffice and OpenOffice have pushed updates to address a vulnerability that makes it possible for an attacker to manipulate documents to appear as signed by a trusted source. Although the severity of the flaw is classified as moderate, the implications could be dire. BleepingComputer reports: The discovery of the flaw, which is tracked as CVE-2021-41832 for OpenOffice, was the work of four researchers at the Ruhr University Bochum. The same flaw impacts LibreOffice, which is a fork of OpenOffice spawned from the main project over a decade ago, and for their project is tracked as CVE-2021-25635. If you're using either of the open-source office suites, you're advised to upgrade to the latest available version immediately. For OpenOffice, that would be 4.1.10 and later, and for LibreOffice, 7.0.5 or 7.1.1 and later. Since neither of these two applications offer auto-updating, you should do it manually by downloading the latest version from the respective download centers -- LibreOffice, OpenOffice. If you're using Linux and the aforementioned versions aren't available on your distribution's package manager yet, you are advised to download the "deb", or "rpm" package from the Download center or build LibreOffice from source. If updating to the latest version is not possible for any reason, you can always opt to completely disable the macro features on your office suite, or avoid trusting any documents containing macros.

New 'FontOnLake' Malware Family Can Target Linux Systems
by Peter Reutemann 11 Oct '21

11 Oct '21

'Security Week reports: A previously unknown, modular malware family that targets Linux systems has been used in targeted attacks to collect credentials and gain access to victim systems, ESET reported on Thursday. Dubbed FontOnLake, the malware family employs a rootkit to conceal its presence and uses different command and control servers for each sample, which shows how careful its operators are to maintain a low profile. What's more, the malware developers are constantly modifying the FontOnLake modules, and use three categories of components that have been designed to work together, namely trojanized applications, backdoors, and rootkits. Evidence suggests that FontOnLake has been used in attacks aimed at organizations in Southeast Asia. The first malware samples related to this family emerged last May. The malware was previously described by Avast and Lacework as the HCRootkit / Sutersu Linux rootkit, as well as by Tencent Security Response Center in a February report. The various trojanized applications that ESET's researchers have identified during their investigation are used to load custom backdoor or rootkit modules, but also to collect sensitive data when needed. Posing as standard Linux utilities, these files were also designed to achieve persistence on the compromised systems. What the researchers haven't figured out yet is the manner in which the trojanized applications are delivered to the victims. ESET's analysis of FontOnLake has revealed the use of three different backdoors, all written in C++, all using the same Asio library from Boost, and all capable of exfiltrating sshd credentials and bash command history. The simplest of the three was designed to launch and mediate access to a local SSH server, update itself, and transmit collected credentials. The malware appears to be under development. The second backdoor was also capable of file manipulation, updating itself, and uploading and downloading files, according to the article, while the third backdoor "accepts remote connections, serves as a proxy and can download and run Python scripts, in addition to exfiltrating credentials."' -- source: https://linux.slashdot.org/story/21/10/10/000240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

All Linux and Mac Computers Get Their Time Zones From the Same Database
by Peter Reutemann 11 Oct '21

11 Oct '21

'"All Linux and Mac-based computers pull their time zones from a massively important database — the time zone database," explains Medium's tech site OneZero. And this vastly crucial project is ultimately overseen by one man who Medium calls "The Time Zone King." The process of defining time zones is centralized. This is actually quite a big deal in its own right because people tend to grossly underestimate how pivotal Linux is to ... the entire internet and technology as we know it... The time zone database — which is sometimes called the Olson data or zoneinfo database — has a fascinating history... Not only are time zones apparently a longstanding menace for computer developers, but the time zone maintenance community is currently, it seems, mired among some procedural dispute regarding how this essential database should best be maintained. Of course that's an interesting fact in its own right: there is a world time zone data community. In fact, The Register recently described them as being no less than " up in arms " about the direction the project was proceeding down... A difference of vision among time zone enthusiasts might be the neatest summary anybody can advance.... Not only can't the time zone titans currently agree on the best way to carry the timezone database forward, it seems. But the entire process of codifying and standardizing time zones is also decidedly contentious political business with a long and tumultuous history to go with it. Those who enter the fray need to be therefore not only technical heavyweights but also prepared to have the occasional audacity to stand up to countries like the Hashemite Republic of Jordan and tell them that their attempt to prematurely end DST is unacceptable and will not be promulgated in the database... Weary time zone mavericks are bursting to the seams with horror stories of African states who made rash time zone decisions on only four days' notice... Time zone data insiders say that every single one of these high stakes deliberations represents a near Y2K disaster that must be averted... At the helm of this project is one individual. One guy. Paul Eggert, a computer scientist who teaches at the Department of Computer Science at the University of California's LA Campus... This is a man, after all, whose codebase helps hundreds of millions of users know what time zone they're in and who — for the past ten years — has gone to bed knowing that hundreds of millions of computers are using his code to know what time zone they're in. He's lived under that pressure for over a decade. And by all accounts thrived... Untold millions have been made by startups announcing dubious advents upon existing technologies heralded with the breathless fanaticism of companies announcing that they have found a way to turn air water into oil. Many of these will vanish into oblivion within a few short years. The time zone database won't. Because it can't. And those at the very bottom of the tech stack — those tirelessly and thanklessly maintaining open source projects upon which so much of the world's computing derives — languish in comparable obscurity... In recent years, the project has fallen under the purview of ICANN [through its Internet Assigned Numbers Authority]. Its code reads like a cross between a JSON file and a historical novel. And while I'm sure the project has many noteworthy contributors, there's ultimately one guy who's responsible for maintaining it. The Time Zone King. His name is Paul Eggert. And he's a computer scientist based out of UCLA. We probably all owe him a 'thank you'.' -- source: https://tech.slashdot.org/story/21/10/10/1950239 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

I can't log into trademe and entering an URL dosen't work
by Michelle 10 Oct '21

10 Oct '21

Hi, I bought on disc the new version of Manjaro Plasma 64 bit KDE because the old Manjaro Illyria 18.0 64 bit I was using stopped working with various things. The new one won't allow me to log into tradme. I enter my email and password and it won't work just like the old one wouldn't. Plasma allows me to see pictures on tumblr whereas the old one stopped allowing that about 2 months ago. And youtube still works. But the new one has another big problem. For security issues I run a computer off a DVD and have no hard drive. When I want to go into any site that requires a password like email or trademe, this is what I do. I boot up, I pull up firefox, I type in the URL for trademe or what have you, and press enter, then and only then do I connect to the internet and click to 'retry' that site and then once at the site the first thing I do is log in. But this new Plasma won't allow me to do that. So could I please have some suggestions for two things: How to make this new one work in those two circumstances AND/OR Some specific names of Operating Systems that will actually allow logging into trademe and will allow URL's to be typed in. Thanks for any help.

Firefox Now Sends Your Address Bar Keystrokes To Mozilla
by Peter Reutemann 10 Oct '21

10 Oct '21

'How-To Geek reports: Firefox now sends more data than you might think to Mozilla. To power Firefox Suggest, Firefox sends the keystrokes you type into your address bar, your location information, and more to Mozilla's servers. Here's exactly what Firefox is sharing and how to control it. This change was made as part of the introduction of Firefox Suggest in Firefox 93, released on October 5, 2021. As part of Firefox Suggest, Firefox is getting ads in your search bar -- but that's not the only thing that will be news to longtime Firefox users. According to Mozilla, "Firefox Suggest acts as a trustworthy guide to the better web, surfacing relevant information and sites to help people accomplish their goals." In reality, what that means is, when you start typing in your address bar, you won't just see the standard search suggestions from Google or your current search default engine. You'll also see "Firefox Suggest" results pointing to web pages. Some of them are sponsored ads, but you can disable the ads. Firefox Suggest is on by default. Mozilla's blog post on the subject says Firefox Suggest is an "opt-in experience," which was the case in September 2021 -- but it's now enabled by default in Firefox 93. However, as of Firefox 93's release in October 2021, Firefox Suggest is only enabled in the USA -- for now. It's worth noting that, for many years, Firefox and other web browsers have had search suggestions in their address bar. So, when you start typing "win" in your address bar, you may see suggestions for "Windows 11" and "Window repair." This is accomplished by sending keystrokes to your default search engine as you type in the search bar, as Mozilla's support site explains. Mozilla is also providing contextual suggestions, for which it needs more data, including the city you're located in and whether you're clicking its suggestions. You can disable Firefox's suggested results, if you like. This will stop Mozilla from collecting the data you type in your search bar, and it will also disable the suggested results and ads. To do so, open Firefox and click menu [and then] Settings. Select "Privacy [and] Security" in the left pane, and scroll down to "Address Bar -- Firefox Suggest." Disable "Contextual suggestions" and "Include occasional sponsored suggestions" to stop Firefox from sending data to Mozilla.' -- source: https://news.slashdot.org/story/21/10/08/2225217 I saw that "Firefox suggest" popping up with the latest 93 as well and, when I tried to turn it off, didn't find the "Firefox suggest" option in the settings dialog that got mentioned in various articles. Something that p...ed me off somewhat... However, looking through the slashdot comments, I came across this github gist called "Silent Firefox": https://gist.github.com/AetherEternity/5a6bb6e493a3d34988fc7342013f2ea6 The top of the file lists where to place this "user.js" file. NB: You might already have such a file, so check before you overwrite it... Personally, I like suggestions from my history (which is turned off in this gist, key: "browser.urlbar.suggest.history"), so I forked the gist and enabled it: https://gist.github.com/fracpete/408ce83d3ce48f9f95b2fea30ddf5403 I'm not particularly fond of this move by Mozilla, but at least you can still tweak its browser (though it's become harder for non-technical people).

Firefox Now Shows Ads As Sponsored Address Bar Suggestions
by Peter Reutemann 08 Oct '21

08 Oct '21

'Mozilla is now showing ads in the form of sponsored Firefox contextual suggestions when U.S. users type in the URL address bar. Mozilla says the feature was introduced with Firefox 92 in September to fund development and optimization. Mozilla describes Firefox Suggest contextual suggestions as opt-in, in BleepingComputer's tests and from what users have reported, the feature is on by default. Furthermore, Firefox doesn't tag the ads displayed via Firefox Suggest. There is no clear way to identify what a sponsored suggestion and what a regular unsponsored suggestion should look like. The only way Firefox users will know whether a sponsored suggestion is an ad would be by looking at the URL, but, in many cases, the URL is not clearly visible.' -- source: https://news.slashdot.org/story/21/10/07/1844254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Apache Fixes Actively Exploited Web Server Zero-day
by Peter Reutemann 06 Oct '21

06 Oct '21

'The Apache Software Foundation has released a security patch to address a vulnerability in its HTTP Web Server project that has been actively exploited in the wild. From a report: Tracked as CVE-2021-41773, the vulnerability affects only Apache web servers running version 2.4.49 and occurs because of a bug in how the Apache server converts between different URL path schemes (a process called path or URI normalization). "An attacker could use a path traversal attack to map URLs to files outside the expected document root," the ASF team said in the Apache HTTP Server 2.4.50 changelog. "If files outside of the document root are not protected by 'require all denied' these requests can succeed. Additionally this flaw could leak the source of interpreted files like CGI scripts," Apache engineers added. More than 120,000 servers currently exposed online to attacks.' -- source: https://apache.slashdot.org/story/21/10/05/1538213 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Company That Routes Billions of Text Messages Quietly Discloses It Was Hacked
by Peter Reutemann 05 Oct '21

'A company that is a critical part of the global telecommunications infrastructure used by AT&T, T-Mobile, Verizon and several others around the world such as Vodafone and China Mobile, quietly disclosed that hackers were inside its systems for years, impacting more than 200 of its clients and potentially millions of cellphone users worldwide. From a report: The company, Syniverse, revealed in a filing dated September 27 with the U.S. Security and Exchange Commission that an unknown "individual or organization gained unauthorized access to databases within its network on several occasions, and that login information allowing access to or from its Electronic Data Transfer (EDT) environment was compromised for approximately 235 of its customers." A former Syniverse employee who worked on the EDT systems told Motherboard that those systems have information on all types of call records. [...] The company wrote that it discovered the breach in May 2021, but that the hack began in May of 2016.' -- source: https://tech.slashdot.org/story/21/10/04/1827246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linus Torvalds On Community, Rust and Linux's Longevity
by Peter Reutemann 04 Oct '21

04 Oct '21

'This week saw the annual check-in with Linux creator Linus Torvalds at the Open Source Summit North America, this year held in Seattle (as well as virtually). Torvalds took the stage for the event's traditional half-hour of questions from Dirk Hohndel, an early Linux contributor (now also the chief open source officer and vice president at VMware) in an afternoon keynote session.... And the theme of community seemed to keep coming up — notably about what that community has ultimately taught Linus Torvalds. (For example, while Torvalds said he'd originally planned on naming the operating system Freax, "I am eternally grateful for two other people for having more taste than I did.") But even then Linux was a project that "I probably would've left behind," Torvalds remembered, "if it was only up to me." Torvalds credits the larger community for its interest (and patches) "that just kept the motivation going. And here we are 30 years later, and it's still what keeps the motivation going. Because as far as I'm concerned, it's been done for 29 of those 30 years, and every single feature ever since has been about things that other people needed or wanted or were interested in." Torvalds also says "I'm very proud of the fact that there's actually a fair number of people still involved with the kernel that came in in 1991 — I mean, literally 30 years ago.... I think that's a testament to how good the community, on the whole, has been, and how much fun it's been." And Torvalds says you can see that sense of fun in discussions about writing some Linux kernel modules using Rust. "From a technical angle, does that make sense?" Torvalds asked. "Who knows. That's not the point. The point is for a project to stay interesting — and to stay fun — you have to play with it.... "Probably next year, we'll start seeing some first intrepid modules being written in Rust, and maybe being integrated in the mainline kernel." "I really love C," Torvalds said at one point. "I think C is a great language, and C is, to me, is really a way to control the hardware at a fairly low level..." Yet Torvalds also saw Hohndel's analogy that it can be like juggling chainsaws. As a long-time watcher of C, Torvalds knows that C's subtle type interactions "are not always logical" and "are pitfalls for pretty much anybody. And they're easy to overlook, and in the kernel that's not always a good thing." Torvalds called Rust "the first language I saw which looked like this might actually be a solution"' -- source: https://linux.slashdot.org/story/21/10/02/004213 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Millions Experience Browser Problems After Long-Anticipated Expiration of 'Let's Encrypt' Certificate
by Peter Reutemann 04 Oct '21

04 Oct '21

'"The expiration of a key digital encryption service on Thursday sent major tech companies nationwide scrambling to deal with internet outages that affected millions of online users," reports the Washington Examiner. The expiring certificate was issued by Let's Encrypt — though ZDNet notes there's been lots of warnings about its pending expiration: Digital Shadows senior cyber threat analyst Sean Nikkel told ZDNet that Let's Encrypt put everyone on notice back in May about the expiration of the Root CA Thursday and offered alternatives and workarounds to ensure that devices would not be affected during the changeover. They have also kept a running forum thread open on this issue with fairly quick responses, Nikkel added. Thursday night the Washington Examiner describes what happened when the big day arrived: Tech giants — such as Amazon, Google, Microsoft, and Cisco, as well as many smaller tech companies — were still battling with an endless array of issues by the end of the night... At least 2 million people have seen an error message on their phones, computers, or smart gadgets in the past 24 hours detailing some internet connectivity problems due to the certificate issue, according to Scott Helme, an internet security researcher and well-known cybersecurity expert. "So many people have been affected, even if it's only the inconvenience of not being able to visit certain websites or some of their apps not working," Helme said. "This issue has been going on for many hours, and some companies are only just getting around to fixing it, even big companies with a lot of resources. It's clearly not going smoothly," he added. There was an expectation before the certificate expired, Helme said, that the problem would be limited to gadgets and devices bought before 2017 that use the Let's Encrypt digital certificate and haven't updated their software. However, many users faced issues on Thursday despite having the most cutting-edge devices and software on hand. Dozens of major tech products and services have been significantly affected by the certificate expiration, such as cloud computing services for Amazon, Google, and Microsoft; IT and cloud security services for Cisco; sellers unable to log in on Shopify; games on RocketLeague; and workflows on Monday.com. Security researcher Scott Helme also told ZDNet he'd also confirmed issues at many other companies, including Guardian Firewall, Auth0, QuickBooks, and Heroku — but there might be many more beyond that: "For the affected companies, it's not like everything is down, but they're certainly having service issues and have incidents open with staff working to resolve. In many ways, I've been talking about this for over a year since it last happened, but it's a difficult problem to identify. it's like looking for something that could cause a fire: it's really obvious when you can see the smoke...!" Digital certificates expert Tim Callan added that the popularity of DevOps-friendly architectures like containerization, virtualization and cloud has greatly increased the number of certificates the enterprise needs while radically decreasing their average lifespan. "That means many more expiration events, much more administration time required, and greatly increased risk of a failed renewal," he said.

FSF Announces 'JShelter' Browser Privacy Extension to Block Fingerprinting, Tracking, and Malware
by Peter Reutemann 04 Oct '21

04 Oct '21

'This week the Free Software Foundation (FSF) announced JShelter, "an anti-malware Web browser extension to mitigate potential threats from JavaScript, including fingerprinting, tracking, and data collection." The browser add-on — supported by NLnet Foundation's Next Generation Internet (NGI) Zero Privacy & Trust Enhancing Technologies fund — is currently "in development and the first release is available." This browser add-on will limit the potential for JavaScript programs to do harmful actions by restricting default behavior and adding a layer of control... Accessing cookies, performing fingerprinting to track users across multiple sites, revealing the local network address, or capturing the user's input before they submit a form are some examples of JavaScript's capabilities that can be used in harmful ways. JShelter adds a safety layer that allows the user to choose if a certain action should be forbidden on a site, or if it should be allowed with restrictions, such as reducing the accuracy of geolocation to the city area. This layer can also aid as a countermeasure against attacks targeting the browser, operating system, or hardware levels... [The extension] will ask — globally or per site — if specific native functions provided by the JavaScript engine and the Document Object Model (DOM) are allowed by the user. It will also link to an explanatory page for each function, to raise awareness of related threats. Depending on the function being addressed, the user will have the option to allow it, block it, or have it return a custom value... "Our browsers have become perhaps the most critical of tools we depend on, and yet the browser environment is far from healthy," says Michiel Leenaars, director of strategy at NLnet Foundation and coordinator of NGI Zero. "Dominant corporate behavior from a small amount of actors has been aggressively reshaping the evolution of the Web, and that is starting to wreak havoc. Despite an enormous systemic dependency, we as users have very little control over what browsers allow and share — leading to significant risk as the most powerful tools in the shed are essentially left unprotected for every casual Web site to abuse. JShelter is a great initiative to help empower us all, to help us gain better understanding and to better safeguard ourselves from obvious and otherwise unavoidable harm." The effort is part of a larger, multi-year campaign from FSF on JavaScript on the Web started in 2013, which among others includes the development of GNU LibreJS and outreach to users and developers about nonfree software inside the browser. The GNU LibreJS extension detects JavaScript web labels and assists users with running only JavaScript distributed under a free software license, according to their ethical convictions and individual preferences. "JShelter will help protect users from critical threats now, and contribute significantly to progress on the necessary longer-term cultural shift of moving away from nonfree JavaScript," said Ruben Rodriguez, former FSF chief technology officer. "This is a project I've been looking forward to for years, tired of dealing with all kinds of potential antifeatures in the browsers I use and distribute, and having to figure out some countermeasure for them with configuration changes, patches or extensions. Being able to wrap the JavaScript engine in a layer of protection is a game changer."' -- source: https://news.slashdot.org/story/21/10/03/0150251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

People Will Pay For Privacy, And Take Rewards To Give It Up
by Lawrence D'Oliveiro 01 Oct '21

01 Oct '21

British consumer magazine “Which?” has published the results of a survey <https://www.theregister.com/2021/09/30/which_data_survey/> which found that people would pay companies like Google and Facebook an average of £1.09 a month to avoid collection of their personal data and its use for targeted advertising. On the other hand, while a quarter of people were happy to receive targeted advertising to begin with, that proportion went up quite substantially if a basic reward like an Amazon voucher were offered.
