Linux Kernel Developers and Commits Dropped in 2019
by Peter Reutemann 06 Jan '20

06 Jan '20

'Phoronix reports that on New Year's Day, the Linux kernel's Git source tree showed 27,852,148 lines of code, divided among 66,492 files (including docs, Kconfig files, user-space utilities in-tree, etc). Over its lifetime there's been 887,925 commits, and around 21,074 different authors: During 2019, the Linux kernel saw 74,754 commits, which is actually the lowest point since 2013. The 74k commits is compares to 80k commits seen in both 2017 and 2018, 77k commits in 2016, and 75k commits in both 2014 and 2015. Besides the commit count being lower, the author count for the year is also lower. 2019 saw around 4,189 different authors to the Linux kernel, which is lower than the 4,362 in 2018 and 4,402 in 2017. While the commit count is lower for the year, on a line count it's about average with 3,386,347 lines of new code added and 1,696,620 lines removed... Intel and Red Hat have remained the top companies contributing to the upstream Linux kernel.' -- source: https://linux.slashdot.org/story/20/01/04/2335200 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/

Employee error to blame for massive data leak, Wyze says
by Peter Reutemann 02 Jan '20

02 Jan '20

'Loads of folks found brand-new Wyze surveillance cameras under their trees or in their stockings this Christmas. And on Boxing Day, the company itself unwrapped a whole new world of trouble for everyone who uses its products, confirming a data leak that may have exposed personal data for millions of users over the course of a few weeks. Wyze first found out about the problem on the morning of December 26, company cofounder Dongsheng Song said in a corporate blog post. The company's investigation confirmed that user data was "not properly secured" and was exposed from December 4 onward. The database in question was basically a copy of the production database that Wyze created to work with, Song explained. Data points left exposed include user email addresses, camera nicknames, Wi-Fi network information, Wyze device information, some tokens associated with Alexa integrations, and "body metrics for a small number of product beta testers."' -- source: https://arstechnica.com/tech-policy/2019/12/surveillance-camera-company-wyz… 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 To Change User-Agent String To Chrome Due To Unfair Blocking
by Peter Reutemann 20 Dec '19

20 Dec '19

'Because some internet websites unfairly block browsers from accessing their services, starting with Vivaldi 2.10, released today, the Vivaldi browser plans to disguise itself as Chrome to allow users to access websites that unfairly block them. From a report: Vivaldi will do this by modifying its default user-agent (UA) string to the UA string used by Chrome. A UA string is a piece of text that browsers send to websites when they initiate a connection. The UA String contains data about the browser type, rendering engine, and operating system. For example, a UA string for Firefox on Windows looks like this: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:71.0) Gecko/20100101 Firefox/71.0. UA strings have been in use since the 90s. For decades, websites have used UA agent strings to fine-tune performance and features or block outdated browsers. However, many website owners these days use UA strings to block users from accessing their sites. Some do it because they're not willing to deal with browser-specific bugs, some do it because of pettiness, while big tech companies like Google and Microsoft have done it (and continue to do it) to sabotage competitors on the browser market.' -- source: https://tech.slashdot.org/story/19/12/19/2041250 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/

Nebula VPN routes between hosts privately, flexibly, and efficiently
by Peter Reutemann 20 Dec '19

20 Dec '19

'Last month, the engineering department at Slack—an instant messaging platform commonly used for community and small business organization—released a new distributed VPN mesh tool called Nebula. It's difficult to coherently explain Nebula in a nutshell. According to the people on Slack's engineering team, they asked themselves "what is the easiest way to securely connect tens of thousands of computers, hosted at multiple cloud service providers in dozens of locations around the globe?" And (developing) Nebula was the best answer they had. It's a portable, scalable overlay networking tool that runs on most major platforms, including Linux, MacOS, and Windows, with some mobile device support planned for the near future. Nebula-transmitted data is fully encrypted using the Noise protocol framework, which is also used in modern, highly security-focused projects such as Signal and WireGuard. Unlike more traditional VPN technologies—including WireGuard—Nebula automatically and dynamically discovers available routes between nodes and sends traffic down the most efficient path between any two nodes rather than forcing everything through a central distribution point.' -- source: https://arstechnica.com/gadgets/2019/12/nebula-vpn-routes-between-hosts-pri… 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/

Facebook is Building an Operating System So it Can Ditch Android
by Peter Reutemann 20 Dec '19

20 Dec '19

'Facebook doesn't want its hardware like Oculus and Portal to be at the mercy of Google because they rely on its Android operating system. >From a report: That's why Facebook has tasked a co-author of Microsoft's Windows NT named Mark Lucovsky with building the social network an operating system from scratch, according the The Information's Alex Heath. "We really want to make sure the next generation has space for us," says Facebook's VP of hardware Andrew 'Boz' Bosworth. "We don't think we can trust the marketplace or competitors to ensure that's the case. And so we're gonna do it ourselves." By moving to its own OS, Facebook could have more freedom to bake social interaction -- and hopefully privacy -- deeper into its devices. It could also prevent a disagreement between Google and Facebook from derailing the roadmaps of Oculus, Portal, or future gadgets. One added bonus of moving to a Facebook-owned operating system? It could make it tougher to force Facebook to spin out some of its acquisitions, especially if Facebook goes with Instagram branding for its future augmented reality glasses.' -- source: https://tech.slashdot.org/story/19/12/19/1747243 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/

Apple, Google, and Amazon team up to create “CHIP,” a new smart home standard
by Peter Reutemann 19 Dec '19

19 Dec '19

'Apple, Google, Amazon, and the Zigbee Alliance have all teamed up to make a new smart home standard. The new working group went live today under the name of "Project Connected Home over IP" with announcement blog posts from Google, Apple, Zigbee, and a new website, connectedhomeip.com. The name doesn't sound too catchy until you realize "Connected Home over IP" abbreviates to "CHIP" which, across all these blog posts, is quietly used only a single time in the official FAQ. According to the new website, "The goal of the Connected Home over IP project is to simplify development for manufacturers and increase compatibility for consumers." But thanks to XKCD, we all know that one new standard to "unite them all" often just results in making one additional standard available, but assuming the companies involved actually support their own standard, this could—maybe—make things easier for consumers.' -- source: https://arstechnica.com/gadgets/2019/12/apple-google-and-amazon-team-up-for… 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/

Hate Speech Row: Fine Or Jail Anyone Who Calls People Boffins, Geeks or Eggheads, Psychology Nerd Demands
by Lawrence D'Oliveiro 19 Dec '19

19 Dec '19

>From <https://www.theregister.co.uk/2019/12/18/nerds_hate_speech/>: Labeling super-smart people with terms like nerd, geek, or boffin is hate speech, and should be punishable as such, argues lecturer and Harley-Street psychotherapist Dr Sonja Falck. ... She then embarked on a “contextual analysis of literature” and decided that calling someone a boffin was equivalent to the worst racial slurs. A couple of points occur to me. One is, one should be careful of the logical pitfalls of arguing “A is no better than B”. Because the flip side of that is that you are also saying “B is no worse than A”. In the process of trying to demonize A, and in the absence of any additional evidence for your position, you could be seen to be trivializing B. The other point is that targeted groups seem to be granted a licence to own terms which are used as slurs against them. These terms become accepted as commonplace inside the group, that nobody outside is allowed to use.

IoT is becoming popular
by leoole123＠yandex.ru 19 Dec '19

19 Dec '19

Smart technologies are rapidly spreading among ordinary users. More and more intelligent and remotely controlled equipment appears in our lives. But let’s see not from the user’s side. Let’s mind like a creator’s. Where is it better to place a “control center”? More and more integrators are transferring their capacities to the public cloud; there is formed a system for management. Labels from all things come through the gateways and are processed directly in the cloud. If the Internet connection is interrupted, all modules continue to work, and immediately after the appearance of the connections are synchronized.

Open Source Gets No Respect, Episode #310
by Lawrence D'Oliveiro 18 Dec '19

18 Dec '19

The developer of FUSE for macOS <https://www.theregister.co.uk/2019/12/16/fuse_macos_closed_source/> found that, while many companies were including his software in their commercial products, they were curiously reluctant to offer him any actual monetary support for his work. So he took the drastic step of making the latest version closed-source. While it continues to be available for non-commercial use at no charge, commercial vendors will need to license it for inclusion in their products. The result? He has actually got a bunch of licensing deals signed now.

Mozilla To Add Second DNS-over-HTTPS (DoH) Provider in Firefox
by Peter Reutemann 18 Dec '19

18 Dec '19

'Mozilla has announced that NextDNS would be joining Cloudflare as the second DNS-over-HTTPS (DoH) provider inside Firefox. From a report: The browser maker says NextDNS passed the conditions imposed by its Trusted Recursive Resolver (TRR) program, and can now be added as a second option for DoH inside Firefox. These conditions include (1) limiting the data NextDNS collects from the DoH server used by Firefox users; (2) being transparent about the data they collect; and (3) promising not to censor, filter, or block DNS traffic unless specifically requested by law enforcement. DNS-over-HTTPS, or DoH, is a new feature that was added to Firefox last year. When enabled, it encrypts DNS traffic coming in and out of the browser. DNS traffic is not only encrypted but also moved from port 53 (for DNS traffic) to port 443 (for HTTPS traffic), effectively hiding DNS queries and replies inside the browser's normal stream of HTTPS content. This encrypted DNS traffic reaches a so-called DoH resolver. Here, the DoH traffic is decrypted and the DoH resolver makes the DNS query on the user's behalf, receives the result, encrypts it, and sends it back to the user's browser -- also disguised inside encrypted HTTPS content.' -- source: https://tech.slashdot.org/story/19/12/17/1922254 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/

Npm Team Warns of New 'Binary Planting' Bug
by Peter Reutemann 17 Dec '19

17 Dec '19

' The team behind npm, the biggest package manager for JavaScript libraries, issued a security alert yesterday, advising all users to update to the latest version (6.13.4) to prevent "binary planting" attacks. From a report: Npm (Node.js Package Manager) devs say the npm command-line interface (CLI) client is impacted by a security bug -- a combination between a file traversal and an arbitrary file (over)write issue. The bug can be exploited by attackers to plant malicious binaries or overwrite files on a user's computer. The vulnerability can be exploited only during the installation of a boobytrapped npm package via the npm CLI. "However, as we have seen in the past, this is not an insurmountable barrier," said the npm team, referring to past incidents where attackers planed backdoored or boobytrapped packages on the official npm repository. Npm devs say they've been scanning the npm portal for packages that may contain exploit code designed to exploit this bug, but have not seen any suspicious cases. "That does not guarantee that it hasn't been used, but it does mean that it isn't currently being used in published packages on the [official npm] registry," npm devs said.' -- source: https://it.slashdot.org/story/19/12/16/1513245 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 Halts Chrome 79 Rollout After It Breaks Some Android Apps
by Peter Reutemann 16 Dec '19

16 Dec '19

'Chrome 79 is creating an issue with WebView (the Android component that allows apps to display content from the web), reports 9to5Google: On Friday morning, Android developers reliant on WebView and local storage began encountering an issue where their apps lost data after users updated to version 79 of WebView. Those affected took to Chromium's bug tracker, and have described the incident as a "catastrophe" and "major issue." To end users, it's as if apps were entirely reset and just downloaded for the first time. This includes saved data disappearing or being logged out. Given the level of system opacity, most will blame developers for a problem that's out of their hands. By that afternoon, Google engineers responded and isolated the issue to "profile layout changes" where "local storage was missed off the list of files migrated." A member of the Chromium team apologized Saturday morning, with the Chrome/WebView rollout halted after 50% of devices already received the update. At the highest priority level (P0), Google is currently "working on a solution that minimizes the data loss, and that can be rolled out safely." The last guidance for a patch is 5-7 days.' -- source: https://tech.slashdot.org/story/19/12/15/181240 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/

'Link in Bio' is a Slow Knife
by Peter Reutemann 15 Dec '19

15 Dec '19

'Anil Dash: We don't even notice it anymore -- "link in bio." It's a pithy phrase, usually found on Instagram, which directs an audience to be aware that a pertinent web link can be found on that user's profile. Its presence is so subtle, and so pervasive, that we barely even noticed it was an attempt to kill the web. Links on the web are incredibly powerful. There are decades of theory behind the role of hyperlinks in hypertext -- did you know in most early versions, links were originally designed to be two-way? You'd be able to see every page on the web that links to this one. But even in the very simple form that we've ended up with on the World Wide Web for the last 30 years, links are incredibly powerful, opening up valuable connections between unexpected things. For a closed system, those kinds of open connections are deeply dangerous. If anyone on Instagram can just link to any old store on the web, how can Instagram -- meaning Facebook, Instagram's increasingly-overbearing owner -- tightly control commerce on its platform? If Instagram users could post links willy-nilly, they might even be able to connect directly to their users, getting their email addresses or finding other ways to communicate with them. Links represent a threat to closed systems. Here's the thing, though: people like links. So closed systems have to present a pressure release valve. Hashtags are a great way out. They use the semiotics of links (early versions of hashtags on social platforms were really barely more than automated links to a search for a particular term) but are also constrained by the platforms they live on. A hashtag is easier to gather into a database, to harvest, to monetize. It's much easier, sure, but it also doesn't have all the messiness of a real link. Instagram doesn't have to worry that clicking on its hashtags will accidentally lead people to Twitter, or vice versa.' -- source: https://tech.slashdot.org/story/19/12/12/1540216 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/

Building Your Own Open Source, Privacy-Protecting Voice Assistant With A Raspberry Pi
by Peter Reutemann 15 Dec '19

15 Dec '19

'PC Magazine's "tech nerd" Whitson Gordon writes that "Once you start using a smart speaker to set reminders, play the news, or turn the lights on, it's hard to go back." But if you want the convenience of voice control without the data-collecting tech giant behind the scenes, an open-source project called Mycroft is a great alternative. And you can run it right on a Raspberry Pi. Mycroft is a free, open-source voice assistant designed to run on Linux-based devices... Mycroft has been around for quite a few years, but it's recently gained a bit more notoriety thanks to privacy concerns surrounding data collection at Amazon and Google. Unlike those assistants, Mycroft only collects data if you opt in during setup. And for the users who do opt in, Mycroft promises never to sell your data to advertisers or third parties -- instead, it only uses it to help developers improve the product. Mycroft even uses the privacy-focused DuckDuckGo as its search engine instead of Google when you ask for information. Mycroft makes its own smart speaker called the Mark I, though it's currently sold out with a new Mark II (video here) on the way. However, since the project is open-source, you can install Mycroft on just about any Linux machine, including the Raspberry Pi (thanks to a pre-made build called Picroft). Using Mycroft on the Pi is free, but you can also subscribe to a $1.99-per-month plan to help support its development -- you'll even get a few goodies, like other voices that sound more lifelike than the default robotic voice.' -- source: https://hardware.slashdot.org/story/19/12/14/1954242 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/

Managing Spectre/Meltdown-Style Vulnerabilities At AWS
by Lawrence D'Oliveiro 15 Dec '19

15 Dec '19

Some insights <https://www.theregister.co.uk/2019/12/10/linux_kernel_aws/> into the different priorities often faced by different groups faced with the same problem. Linux kernel developer Greg Kroah-Hartman says to avoid most of these “MDS” (“Microarchitectural Data Sampling”) vulnerabilities, you must turn off Intel’s hyperthreading, full stop. Amazon, on the other hand, find that the resulting 30-40% performance loss is unacceptable for many of their customers. So they have come up with a tweaked scheduler algorithm for their Linux kernels that avoids running two different guests on the same physical core at the same time. With this and other careful management, they claim to be able to keep their customers safe from each other, with much less dramatic performance impact. But then you have the downside that the mainline kernel is not interested in accepting patches with such narrow applicability. Of course Amazon would like to come up with something they will accept, just to reduce their own maintenance burden.

Mozilla To Force All Add-on Devs To Use 2FA To Prevent Supply-Chain Attacks
by Peter Reutemann 14 Dec '19

14 Dec '19

'Mozilla announced this week that all developers of Firefox add-ons must enable a two-factor authentication (2FA) solution for their account. From a report: "Starting in early 2020, extension developers will be required to have 2FA enabled on AMO [the Mozilla Add-Ons portal]," said Caitlin Neiman, Add-ons Community Manager at Mozilla. "This is intended to help prevent malicious actors from taking control of legitimate add-ons and their users," Neiman added. When this happens, hackers can use the developers' compromised accounts to ship tainted add-on updates to Firefox users. Since Firefox add-ons have a pretty privileged position inside the browser, an attacker can use a compromised add-on to steal passwords, authentication/session cookies, spy on a user's browsing habits, or redirect users to phishing pages or malware download sites. These types of incidents are usually referred to as supply-chain attacks.' -- source: https://it.slashdot.org/story/19/12/13/152239 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/

Russian Police Raid NGINX Moscow Office

'Russian police have raided today the Moscow offices of NGINX, Inc., a subsidiary of F5 Networks and the company behind the internet's most popular web server technology. From a report: Equipment was seized and employees were detained for questioning. Moscow police executed the raid after last week the Rambler Group filed a copyright violation against NGINX Inc., claiming full ownership of the NGINX web server code. The Rambler Group is the parent company of rambler.ru, one of Russia's biggest search engines and internet portals. According to copies of the search warrant posted on Twitter today, Rambler claims that Igor Sysoev developed NGINX while he was working as a system administrator for the company, hence they are the rightful owner of the project. Sysoev created NGINX in the early 2000s and open-sourced the NGINX code in 2004. In 2009, he founded NGINX, Inc., a US company, to provide adjacent tools and support services for NGINX deployments. The company is based in San Francisco, but has offices all over the world, including Moscow. The NGINX server's source code is still free and managed through an open-source model, although a large chunk of the project's primary contributors are NGINX, Inc. employees, who have a firm grip on the project's stewardship.' -- source: https://news.slashdot.org/story/19/12/12/175245 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/

Inside the Podcast that Hacks Ring Camera Owners Live on Air
by Peter Reutemann 13 Dec '19

13 Dec '19

'In the NulledCast podcast hackers livestream the harassment of Ring camera owners after accessing their devices. Hundreds of people can listen. From a report: A blaring siren suddenly rips through the Ring camera, startling the Florida family inside their own home. "It's your boy Chance on Nulled," a voice says from the Ring camera, which a hacker has taken over. "How you doing? How you doing?" "Welcome to the NulledCast," the voice says. The NulledCast is a podcast livestreamed to Discord. It's a show in which hackers take over people's Ring and Nest smarthome cameras and use their speakers to talk to and harass their unsuspecting owners. In the example above, Chance blared noises and shouted racist comments at the Florida family. "Sit back and relax to over 45 minutes of entertainment," an advertisement for the podcast posted to a hacking forum called Nulled reads. "Join us as we go on completely random tangents such as; Ring & Nest Trolling, telling shelter owners we killed a kitten, Nulled drama, and more ridiculous topics. Be sure to join our Discord to watch the shows live." Software to hack Ring cameras has recently become popular on the forum. The software churns through previously compromised email addresses and passwords to break into Ring cameras at scale. This has led to a recent spate of hacks that have occurred both during the podcast and at other times, several of which have been covered by local media outlets. In Brookhaven a hacker shouted at a sleeping woman through her hacked Ring camera to wake-up. In Texas, a hacker demanded a couple pay a bitcoin ransom. Hackers targeted a family in DeSoto County, Mississippi, and spoke through the device to one of the young children.' -- source: https://yro.slashdot.org/story/19/12/12/204240 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/

Intel’s SGX coughs up crypto keys when scientists tweak CPU voltage
by Peter Reutemann 11 Dec '19

11 Dec '19

'To counter the growing sophistication of computer attacks, Intel and other chip makers have built digital vaults into CPUs to segregate sensitive computations and secrets from the main engine computers use. Now, scientists have devised an attack that causes the Software Guard Extensions—Intel's implementation of this secure CPU environment to divulge cryptographic keys and induce potentially dangerous memory errors. Plundervault, as the attack has been dubbed, starts with the assumption that an attacker is able to run privileged software on a targeted computer. While that's a lofty prerequisite, it's precisely the scenario Intel's SGX feature is designed to protect against. The chipmaker bills SGX as a private region that uses hardware-based memory encryption to isolate sensitive computations and data from malicious processes that run with high privilege levels. Intel goes as far as saying that "Only Intel SGX offers such a granular level of control and protection." But it turns out that subtle fluctuations in voltage powering the main CPU can corrupt the normal functioning inside the SGX. By subtly increasing or decreasing the current delivered to a CPU—operations known as "overvolting" and "undervolting"—a team of scientists has figured out how to induce SGX faults that leak cryptographic keys, break integrity assurances, and potentially induce memory errors that could be used in other types of attacks.' -- source: https://arstechnica.com/information-technology/2019/12/scientists-pluck-cry… 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/

Are You One Of Avast's 400 Million Users? This Is Why It Collects And Sells Your Web Habits.
by Peter Reutemann 11 Dec '19

11 Dec '19

'Avast, the multibillion-dollar Czech security company, doesn't just make money from protecting its 400 million users' information. It also profits in part because of sales of users' Web browsing habits and has been doing so since at least 2013. From a report: That's led to some labelling its tools "spyware," the very thing Avast is supposed to be protecting users from. Both Mozilla and Opera were concerned enough to remove some Avast tools from their add-on stores earlier this month, though the anti-virus provider says it's working with Mozilla to get its products back online. But recently appointed chief executive Ondrej Vlcek tells Forbes there's no privacy scandal here. All that user information that it sells cannot be traced back to individual users, he asserts. Here's how it works, according to Vlcek: Avast users have their Web activity harvested by the company's browser extensions. But before it lands on Avast servers, the data is stripped of anything that might expose an individual's identity, such as a name in the URL, as when a Facebook user is logged in. All that data is analysed by Jumpshot, a company that's 65%-owned by Avast, before being sold on as "insights" to customers. Those customers might be investors or brand managers. What do those customers get? Vlcek says Jumpshot, which was initially acquired in 2013, provides "insights on how cohorts of users on the internet use the web." For instance, it could show a percentage of visitors who went from one website to another. That could be useful to anyone monitoring an advertising campaign. "Typical customers would be, for example, investors, who would be interested in how online companies are doing in terms of their new campaigns," the new Avast chief explains. Say Amazon launches a new product -- Jumpshot could determine how much interest it's getting online.' -- source: https://it.slashdot.org/story/19/12/10/1922243 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/

Yahoo Groups Is Winding Down and All Content Will Be Permanently Removed
by Peter Reutemann 10 Dec '19

'Yahoo announced on Wednesday that it is winding down its long-running Yahoo Groups site. From a report: As of October 21, users will no longer be able to post new content to the site, and on December 14 Yahoo will permanently delete all previously posted content. "You'll have until that date to save anything you've uploaded," an announcement post reads. Yahoo Groups, launched in 2001, is a cross between a platform for mailing lists and internet forums. Groups can be interacted with on the Yahoo Groups site itself, or via email. In the 18 years that it existed, numerous niche communities made a home on the platform. Now, with the site's planned obsolescence, users are looking for ways to save their Groups history.' -- source: https://tech.slashdot.org/story/19/10/16/1928228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

WireGuard VPN is a step closer to mainstream adoption
by Peter Reutemann 10 Dec '19

10 Dec '19

'As of this morning, Linux network stack maintainer David Miller has committed the WireGuard VPN project into the Linux "net-next" source tree. Miller maintains both net and net-next—the source trees governing the current implementation of the Linux kernel networking stack and the implementation of the next Linux kernel's networking stack, respectively. This is a major step forward for the WireGuard VPN project. Net-next gets pulled into the new Linux kernel during its two-week merge window, where it becomes net. With WireGuard already a part of net-next, this means that—barring unexpected issues—there should be a Linux kernel 5.6 release candidate with built-in WireGuard in early 2020. Mainline kernel inclusion of WireGuard should lead to significantly higher uptake in projects and organizations requiring virtual private network capability. Normal, day-to-day Linux users probably won't see in-kernel WireGuard until late 2020. Ubuntu is one of the faster-moving mainstream distributions, and its next Long Term Support (LTS) release is in April 2020. But the Linux 5.6 kernel and Ubuntu 20.04 will likely be in release candidate status at the same time, so its inclusion in 20.04 seems unlikely. The interim 20.10 Ubuntu release seems like a much safer bet for Canonical's first use of a 5.6 or later kernel. Red Hat Enterprise Linux (RHEL) inclusion will likely be a year or more beyond that; the current RHEL 8.1 shipped in May 2019 with the 4.18 kernel, which was already 9 months old. Although highly speculative, it's also possible that WireGuard could land in-kernel on Ubuntu 20.04 even without the 5.6 kernel—Donenfeld offered to do the work backporting WireGuard into earlier Ubuntu kernels directly. Donenfeld also stated today that a 1.0 WireGuard release is "on the horizon."' -- source: https://arstechnica.com/gadgets/2019/12/wireguard-vpn-is-a-step-closer-to-m… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Users Can Now Use Disney+ After DRM Fix
by Peter Reutemann 09 Dec '19

09 Dec '19

'"Linux users can now stream shows and movies from the Disney+ streaming service after Disney lowered the level of their DRM requirements," reports Bleeping Computer: When Disney+ was first launched, Linux users who attempted to watch shows and movies were shown an error stating "Something went wrong. Please try again. If the problem persists, visit the Disney+ Help Center (Error Code 83)." As explained by Hans de Goede, this error was being caused by the Disney+ service using the highest level of security for the Widevine Digital Rights Management (DRM) technology. As some Linux and Android devices did not support this higher DRM security level, they were unable to stream Disney+ shows in their browsers... Yesterday, Twitter users discovered that Disney+ had suddenly started working on Linux browsers after the streaming service tweaked their DRM security levels... Even with Disney+ lowering the DRM requirements, users must first make sure DRM is enabled in the browser. For example, Disney+ will not work with Firefox unless you enable the "Play DRM-controlled content" setting in the browser.' -- source: https://linux.slashdot.org/story/19/12/08/169213 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/

Qualcomm To Offer GPU Driver Updates On Google Play Store For Some Snapdragon Chips
by Peter Reutemann 08 Dec '19

08 Dec '19

'At its Snapdragon Summit in Maui, Hawaii this week, Qualcomm unveiled the new Snapdragon 865 Mobile Platform, which enable next year's flagship 5G Android phones with more performance, a stronger Tensor-based AI processor and a very interesting new forthcoming feature not yet offered for any smartphone platform to date. The company announced that it will eventually start delivering driver updates for its Adreno GPU engines on board the Snapdragon 865 as downloadable packages via the Google Play Store. This is big news for smartphones, as GPU drivers are rarely updated out of band, if ever, and typically have to wait for the next major Android release. And even then, many OEMs don't bother putting in the effort to ensure that mobile GPUs are running the most current graphics drivers from Qualcomm. The process, which would have to be pre-qualified by major OEMs as well, will be akin to what the PC GPU 3D graphics driver ecosystem has been benefiting from for a long time, for maximum performance and compatibility. Unfortunately, at least currently, GPU driver update support is limited to only the Adreno 650 core on board the new Snapdragon 865, which currently supports updating drivers in this fashion. Here's hoping this program is met with success and Qualcomm will begin to enable the feature for legacy and new midrange Snapdragon platforms as well.' -- source: https://tech.slashdot.org/story/19/12/06/2132212 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/

Keybase Moves To Stop Onslaught of Spammers on Encrypted Message Platform
by Peter Reutemann 07 Dec '19

07 Dec '19

'Keybase started off as co-founder and developer Max Krohn's "hobby project" -- a way for people to share PGP keys with a simple username-based lookup. Then Chris Coyne (who also was cofounder of OkCupid and SparkNotes) got involved and along came $10.8 million in funding from a group of investors led by Andreesen Horowitz. And then things got increasingly more complicated. Keybase aims to make public-key encryption accessible to everyone, for everything from messaging to file sharing to throwing a few crypto-coins someone's way. But because of that level of accessibility, Keybase faces a very OkCupid kind of problem: after drawing in people interested in easy public-key crypto-based communications and then drawing in blockchain lovers with its partnership with (and funding from) Stellar.org, Keybase has also drawn in spammers and scammers. And that has brought a host of alerts and messages that have made what was once a fairly clear communications channel into one clogged with unwanted alerts, messages, and other unpleasantry -- raising a chorus of complaints in Keybase's open chat channel. It turns out there's a reason spell check keeps wanting to tell me that Keybase should be spelled "debase." Keybase's leadership is promising to do something to fix the spam problem -- or at least make it easier to report and block abusers. In a blog post, Krohn and Coynes wrote, "To be clear, the current spam volume isn't dire, YET. Keybase still works great. But we should act quickly." But the measures promised by Keybase won't completely eliminate the issue. And Keybase execs have no interest in getting involved with additional steps that they see as censorship. "Keybase is a private company and we do retain our rights to kick people out," the co-founders said in the blog post. "That hammer will not be used because someone is mostly disliked, as long as they're playing nicely on Keybase."' -- source: https://it.slashdot.org/story/19/12/06/1610259 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 Linux Vulnerability Lets Attackers Hijack VPN Connections
by Peter Reutemann 06 Dec '19

06 Dec '19

'Security researchers found a new vulnerability allowing potential attackers to hijack VPN connections on affected *NIX devices and inject arbitrary data payloads into IPv4 and IPv6 TCP streams. They disclosed the security flaw tracked as CVE-2019-14899 to distros and the Linux kernel security team, as well as to others impacted such as Systemd, Google, Apple, OpenVPN, and WireGuard. The vulnerability is known to impact most Linux distributions and Unix-like operating systems including FreeBSD, OpenBSD, macOS, iOS, and Android. A currently incomplete list of vulnerable operating systems and the init systems they came with is available below, with more to be added once they are tested and found to be affected: Ubuntu 19.10 (systemd), Fedora (systemd), Debian 10.2 (systemd), Arch 2019.05 (systemd), Manjaro 18.1.1 (systemd), Devuan (sysV init), MX Linux 19 (Mepis+antiX), Void Linux (runit), Slackware 14.2 (rc.d), Deepin (rc.d), FreeBSD (rc.d), and OpenBSD (rc.d). This security flaw "allows a network adjacent attacker to determine if another user is connected to a VPN, the virtual IP address they have been assigned by the VPN server, and whether or not there is an active connection to a given website," according to William J. Tolley, Beau Kujath, and Jedidiah R. Crandall, Breakpointing Bad researchers at University of New Mexico. "Additionally, we are able to determine the exact seq and ack numbers by counting encrypted packets and/or examining their size. This allows us to inject data into the TCP stream and hijack connections," the researchers said.' -- source: https://linux.slashdot.org/story/19/12/05/2022205 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/

Brother of Drug Lord Pablo Escobar Launches 'Unbreakable' Foldable Smartphone
by Peter Reutemann 05 Dec '19

05 Dec '19

'Roberto Escobar, brother of the late drug lord Pablo Escobar, has announced a foldable smartphone that is "very difficult to break" thanks to the screen's "special type of plastic." The Escobar Fold 1, as it is called, significantly undercuts Samsung's Galaxy Fold and Huawei Mate X with a price of only $349. Neowin reports: While all the foldable phones announced so far have a price tag of at least $1,500+, the Escobar Fold 1 will be available from only $349 which includes free shipping and a case as well. It will be sold unlocked and work on all compatible networks worldwide. This makes it cheaper than other non-foldable flagship smartphones available in the market right now. The drug lord's brother has been able to price the phone so low by cutting out the middlemen like networks and retailers. He is also preparing to file a $30 billion class-action lawsuit against Apple for scamming people and wants the company to "give some of their illegal profits back to the people." Like the Huawei Mate X, the Escobar Fold can be unfolded to turn it into a tablet with a screen size of 7.8-inches. The expanded AMOLED display has a 4:3 aspect ratio and an FHD+ resolution. The design language is different from the Samsung Galaxy Fold which features two separate displays, one of which folds.

The Rise and Fall of the PlayStation Supercomputers
by Peter Reutemann 04 Dec '19

04 Dec '19

'"On the 25th anniversary of the original Sony PlayStation, The Verge shares the story of the PlayStation supercomputers," writes Slashdot reader jimminy_cricket. From the report: Dozens of PlayStation 3s sit in a refrigerated shipping container on the University of Massachusetts Dartmouth's campus, sucking up energy and investigating astrophysics. It's a popular stop for tours trying to sell the school to prospective first-year students and their parents, and it's one of the few living legacies of a weird science chapter in PlayStation's history. Those squat boxes, hulking on entertainment systems or dust-covered in the back of a closet, were once coveted by researchers who used the consoles to build supercomputers. With the racks of machines, the scientists were suddenly capable of contemplating the physics of black holes, processing drone footage, or winning cryptography contests. It only lasted a few years before tech moved on, becoming smaller and more efficient. But for that short moment, some of the most powerful computers in the world could be hacked together with code, wire, and gaming consoles. "The game consoles entered the supercomputing scene in 2002 when Sony released a kit called Linux for the PlayStation 2," reports The Verge. Craig Steffen, senior research scientist at the National Center for Supercomputing Applications, and his group hooked up between 60 and 70 PlayStation 2s, wrote some code, and built out a library. "The PS3 entered the scene in late 2006 with powerful hardware and an easier way to load Linux onto the devices," the report adds. "Researchers would still need to link the systems together, but suddenly, it was possible for them to imagine linking together all of those devices into something that was a game-changer instead of just a proof-of-concept prototype."' -- source: https://hardware.slashdot.org/story/19/12/03/2214249 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/

elementary OS 5.1 'Hera' Linux Distro is Here
by Peter Reutemann 04 Dec '19

04 Dec '19

'elementary OS has long been viewed by many as the future of Linux on the PC thanks to its beautiful desktop environment and overall polished experience. Development of the Ubuntu-based operating system has been frustratingly slow, however. This shouldn't be surprising, really, as the team of developers is rather small, and its resources are likely much less than those of larger distributions such as the IBM-backed Fedora or Canonical's Ubuntu. And that is what makes elementary OS so remarkable -- its developers can make magic on a smaller budget. Today, the latest version of the operating system is released. Code-named "Hera," elementary OS 5.1 is now available for download. Support for Flatpak is now baked in -- this is significant, as the developers explain it is "the first non-deb packaging format we've supported out of the box." The Linux kernel now sits at a very modern 5.0. One of the most important aspects of elementary OS, the AppCenter, is now an insane 10 times faster than its predecessor.' -- source: https://tech.slashdot.org/story/19/12/03/1538207 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/

Mozilla Removes Avast and AVG Extensions From Add-on Portal Over Snooping Claims
by Peter Reutemann 04 Dec '19

04 Dec '19

'Mozilla today removed four Firefox extensions made by Avast and its subsidiary AVG after receiving credible reports that the extensions were harvesting user data and browsing histories. From a report: The four extensions are Avast Online Security, AVG Online Security, Avast SafePrice, and AVG SafePrice. The first two are extensions that show warnings when navigating to known malicious or suspicious sites, while the last two are extensions for online shoppers, showing price comparisons, deals, and available coupons. Mozilla removed the four extensions from its add-ons portal after receiving a report from Wladimir Palant, the creator of the AdBlock Plus ad-blocking extension. Palant analyzed the Avast Online Security and AVG Online Security extensions in late October and found that the two were collecting much more data than they needed to work -- including detailed user browsing history, a practice prohibited by both Mozilla and Google.' -- source: https://yro.slashdot.org/story/19/12/03/1559248 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/

Vulnerability In Fully Patched Android Phones Under Active Attack By Bank Thieves
by Peter Reutemann 03 Dec '19

03 Dec '19

'A vulnerability in millions of fully patched Android phones is being actively exploited by malware that's designed to drain the bank accounts of infected users, researchers said on Monday. The vulnerability allows malicious apps to masquerade as legitimate apps that targets have already installed and come to trust, researchers from security firm Promon reported in a post. Running under the guise of trusted apps already installed, the malicious apps can then request permissions to carry out sensitive tasks, such as recording audio or video, taking photos, reading text messages or phishing login credentials. Targets who click yes to the request are then compromised. Researchers with Lookout, a mobile security provider and a Promon partner, reported last week that they found 36 apps exploiting the spoofing vulnerability. The malicious apps included variants of the BankBot banking trojan. BankBot has been active since 2017, and apps from the malware family have been caught repeatedly infiltrating the Google Play Market. The vulnerability is most serious in versions 6 through 10, which account for about 80% of Android phones worldwide. Attacks against those versions allow malicious apps to ask for permissions while posing as legitimate apps. There's no limit to the permissions these malicious apps can seek. Access to text messages, photos, the microphone, camera, and GPS are some of the permissions that are possible. A user's only defense is to click "no" to the requests. "The vulnerability is found in a function known as TaskAffinity, a multitasking feature that allows apps to assume the identity of other apps or tasks running in the multitasking environment," reports Ars Technica. While Google has removed the [unnamed] malicious apps from its Play Store, according to Promon, the vulnerability is still unfixed in all versions of Android. "Promon is calling the vulnerability 'StrandHogg,' an old Norse term for the Viking tactic of raiding coastal areas to plunder and hold people for ransom," the report adds. "Promon researchers said they identified StrandHogg after learning from an unnamed Eastern European security company for financial institutions that several banks in the Czech Republic reported money disappearing from customer accounts."' -- source: https://it.slashdot.org/story/19/12/02/230254 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/

Huawei Is Now Making Smartphones Without American Chips
by Peter Reutemann 03 Dec '19

03 Dec '19

'"American tech companies are getting the go-ahead to resume business with Chinese smartphone giant Huawei Technologies Co., but it may be too late," reports the Wall Street Journal. Huawei is just building its smartphones without U.S. chips. Huawei's latest phone, which it unveiled in September -- the Mate 30 with a curved display, telephone and wide-angle cameras that competes with Apple Inc.'s iPhone 11 -- contained no U.S. parts, according to an analysis by UBS and Fomalhaut Techno Solutions, a Japanese technology lab that took the device apart to inspect its insides... While Huawei hasn't stopped using American chips entirely, it has reduced its reliance on U.S. suppliers or eliminated U.S. chips in phones launched since May, including the company's Y9 Prime and Mate smartphones, according to Fomalhaut's teardown analysis. Similar inspections by iFixit and Tech Insights Inc., two other firms that take apart phones to inspect components, have come to similar conclusions.' -- source: https://mobile.slashdot.org/story/19/12/02/0146208 Looks like actual competition now...

Rust-Based Redox OS Is Nearly Self-Hosting After Four Years
by Peter Reutemann 02 Dec '19

02 Dec '19

'Redox OS, written in Rust and currently under development, is only "a few months of work away" from self-hosting, meaning that the Rustc compiler would run on Redox itself, according to its creator Jeremy Soller... Redox has a POSIX-compliant C library written in Rust, called relibc. It is Linux-compatible both at the syscall API level and at the syscall ABI (Application binary interface) level, subject to the same architecture. The article notes that the OS's latest release was version 0.5 last March, arguing that it's "best described as experimental..." "Still, if Rust continues to grow in popularity, its characteristics of safety and unimpeded performance seem ideal for creating a new operating system, so perhaps Redox will become more prominent."' -- source: https://linux.slashdot.org/story/19/11/30/2011231 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/

Kali Linux Adds 'Undercover' Mode to Impersonate Windows 10
by Peter Reutemann 02 Dec '19

02 Dec '19

'"Kali Linux 2019.4 was released last week and with it comes an 'Undercover' mode that can be used to quickly make the Kali desktop look like Windows 10," reports Bleeping Computer: Kali is a Linux distribution created for ethical hacking and penetration testing and is commonly used by researchers and red teamers to perform security tests against an organization. As most people are used to seeing Windows and macOS devices being used, it may look suspicious to see a user running Kali Linux with it's distinctive dragon logo and a Linux environment in an office lobby or other public setting. With this in mind, in Kali Linux 2019.4 the developers created a new 'Undercover' mode that will make the desktop look similar to Windows 10 in order to draw less suspicion. The script even hides Kali's dragon logo, explains a post on the Kali blog, so "you can work a bit more incognito. After you are done and in a more private place, run the script again and you switch back to your Kali theme. Like magic...!" "Thanks to Robert, who leads our penetration testing team, for suggesting a Kali theme that looks like Windows to the casual view..."' -- source: https://linux.slashdot.org/story/19/12/01/1825215 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 File /var/lib/dbus/machine-id Matters For Your Privacy (and Devuan Fixed It)

'A few days ago Devuan ASCII 2.1 was announced and one update has been overlooked by most media outlets: our dbus patch to re-generate machine-id at every boot. This patch matters for everyone's privacy and I hope more distributions will follow our example, let alone Debian. We are dealing with important privacy implications: non-consensual user tracking is illegal in many countries and is not even mentioned in the machine-id documentation so far.

Ubuntu 19.10: It’s fast, like “make old hardware feel new” fast
by Peter Reutemann 28 Nov '19

28 Nov '19

'Leaves are turning. Temperatures have dipped. These are sure signs—if you live in the Northern Hemisphere, at least—that Canonical's Autumn release is upon us. Things are a bit different in 2019, however. Not only is Ubuntu 19.10 nicknamed Eoan Ermine (no, I don't know how you pronounce it either), but it's the best non-LTS Ubuntu release Canonical has ever put out. I should qualify that statement somewhat, because really, as the newest version, it had damn well better be the best Ubuntu ever. But there's more than recency bias behind the sentiment. I've been reviewing Ubuntu for 10 years now, and I was using and interacting with this distro in some form or another for another three or four years before that. After spending recent weeks with Ubuntu 19.10, I can say confidently it is quite simply the best Ubuntu Canonical has ever released. The first reason I like 19.10 so much is that it feels insanely fast. Everyday tasks like opening applications, dragging windows, activating the search interface, and even just moving the cursor around are all noticeably faster than in 19.04. The speed boost is immediately noticeable from the minute you pop in the live CD, and it's even faster once you have 19.10 installed. I happened to be testing a top-of-the-line MacBook around the time I first installed the 19.10 beta on my aging Lenovo x240, and it instantly made the Mac feel like a sloth. Ubuntu 19.10 ran circles around the Mac even on much, much less powerful hardware, and nothing says success during testing like software that makes old hardware feel newer. Even if that were all you got out of Ubuntu 19.10, I'd call it a win.' -- source: https://arstechnica.com/gadgets/2019/11/ubuntu-19-10-quite-simply-the-best-… 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/

tagging arbitrary files (not just mp3s) under Linux
by Peter Reutemann 26 Nov '19

26 Nov '19

Hi everyone After last night's AGM, I had a conversation with Rod regarding any Linux applications that allow tagging of arbitrary files (not just mp3s) to improve organizing them, similar to what Gmail introduced all those years ago. In the following reddit discussion: https://www.reddit.com/r/linux/comments/3mjwn5/do_any_popular_linux_file_sy… I came across the "TagSpaces" application (open source, AGPL), which seems to fit that bill: https://www.tagspaces.org/ 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/

Passive-Cooling A Raspberry π 4
by Lawrence D'Oliveiro 26 Nov '19

26 Nov '19

Just came across this video <https://www.youtube.com/watch?v=VJC6OpGpq0Y>, latest in a series on cooling solutions for a Raspberry π 4. This instalment looks at a couple of purely passive, fanless products that use the case as a heat sink (or vice versa). But on top of that, a recent firmware update from Broadcom has made a massive difference to the running temperature in all the configurations. Summary: passive cooling worked quite well before the update, and now works even better.

The Librem 5 has been “shipping” for a month—but not to backers
by Peter Reutemann 26 Nov '19

26 Nov '19

'Purism announced that shipping of its Librem 5 open source smartphone began in late September. Two months later, nobody outside the company has a Librem 5, and people are getting restless. The Librem 5 is a crowdfunded project—and an ambitious one—so it wasn't much surprise or cause for concern when it missed its original January 2019 delivery target—or the April 2019 target set after January slipped. Both date changes were announced well ahead of time, and the company continued to post progress reports, commit code upstream, and assure backers of its commitment to transparency. (Full disclosure: I am a Librem 5 backer myself and am scheduled to receive a phone in the Evergreen batch.) The new delays are more troubling. On September 5, CEO Todd Weaver announced that the Librem 5 would ship in six iterative batches, codenamed Aspen, Birch, Chestnut, Dogwood, Evergreen, and Fir. The first three batches would effectively be usable prototypes of decreasing roughness; Evergreen would be the first entirely finished hardware production run, and Fir would be a relatively unspecified next-generation design.' -- source: https://arstechnica.com/gadgets/2019/11/the-librem-5-has-been-shipping-for-… 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/

Mozilla's Annual Buyer's Guide Rates Amazon and Google Security Cameras 'Very Creepy'
by Peter Reutemann 26 Nov '19

26 Nov '19

'"Be Smart. Shop Safe," warns Mozilla's annual buyer's guide for secure connected products. Based on their conversations with developers and dozens of privacy experts, they've awarded smiley faces with different expressions to rate products from "Not Creepy" up to "Super Creepy". "While the variety of smart devices on offer is rapidly increasing, so are the number of products that pay no heed to even basic security measures..." notes the editor of Mozilla's Internet Health Report. "Now that more and more companies collect personal data about you, including audio and video of your family, and sensitive biometric and health information, like your heart rate and sleeping habits, it's worrying that more are not upfront about the privacy and security of their products." Or, as The Next Web writes, "god bless Mozilla for having our lazy backs." And, well, if you're a user of any Ring camerasâ¦ we're sorry. Basically, there are five things that every product must do: - Have automatic security updates, so they're protected against the newest threats - Use encryption, meaning bad actors can't just snoop on your data - Include a vulnerability management pathway, which makes reporting bugs easy and, well, possible - Require users to change the default password (if applicable), because that makes devices far harder to access - Privacy policies -- ones that relate to the product specifically, and aren't just generic Doesn't seem too much to ask right...? Well, of the 76 devices Mozilla selected, 60 of them passed this test... And what devices didn't meet the criteria? There were nine of them overall (including the Artie 3000 Coding Robot and the Wemo Wifi Smart Dimmer), but the real loser in this test is the Amazon-owned Ring. Three of the company's products (which is effectively all of their major devices) didn't meet Mozilla's criteria. Yes, that's right, the Ring Video Doorbell, Ring Indoor Cam, and Ring Security Cam all didn't meet minimum standards for security.... The main reasons for not meeting this criteria is due Ring's history with poor encryption policies, and vulnerability management. To be fair, Nest Cam's Indoor and Outdoor Security Cameras and Google Home also fell into the "Very Creepy" category -- and so did Amazon's Echo smart speakers. (The Amazon Echo Show even made it into Mozilla's highest "Super Creepy" category, where the only other product was Facebook Portal.) But at least the Nest Hello Video doorbell only appears in Mozilla's "Somewhat Creepy" category. "Just because something on your wishlist this year connects to the internet, doesn't mean you have to compromise on privacy and security..." warns the editor of Mozilla's Internet Health Report. And in addition, "Fitness trackers designed for kids as young as 4 years old, raise questions about what we are teaching our children about how much digital surveillance in their lives is normal." Going forward, they suggest that we push for better privacy regulations -- and that whenever we rate products on performance and price, we should also rate them on their privacy and security. But in the meantime, as Mozilla explained on Twitter, "Friends don't let friends buy creepy gifts."' -- source: https://yro.slashdot.org/story/19/11/25/0415202 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/

Web Creator Tim Berners-Lee Launches Plan To 'Fix' the Internet
by Peter Reutemann 26 Nov '19

26 Nov '19

'Tim Berners-Lee, the creator of the World Wide Web, is officially launching his plan to "fix" the internet. From a report: The World Wide Web Foundation, a non-profit campaign group set up by Berners-Lee, has secured the backing of tech giants Facebook, Google and Microsoft for the scheme, dubbed the "contract for the web." The British computer scientist first outlined his vision to overhaul organizations' approach to the internet at the Web Summit event last year. At the time, he said the web was "at a tipping point." The contract calls on companies to respect consumers' data privacy and urges governments to ensure everyone has access to the internet. "Never before has the web's power for good been more under threat," Adrian Lovett, CEO of the World Wide Web Foundation, told CNBC in an interview Friday. He added that the rise of hateful content and fake news being propagated online meant something had to change. "We're launching the contract for the web for the world's first-ever global action plan to protect the web as a force for good, bringing together companies, governments and citizens from around the world to say these are the things that need to be done to put things back on the right track." Other organizations backing the contract include DuckDuckGo, Reddit, GitHub and Reporters Without Borders. One major component of the pledge is the requirement that the web remains an accessible tool for all users. Lovett said that, "despite the progress we've seen in getting the world connected, half the world doesn't have access." He said the contract comes with nine core principles, while underneath them is a total of 76 clauses. "Not every organization has to abide by all of them," he insisted. "A good number of those 76 will be relevant." Berners-Lee will deliver a speech in Berlin, Germany, on Monday where he is due to say the contract will serve as a blueprint for governments, companies and citizens to safeguard the web as a force for good. The World Wide Web Foundation says it is working with partners to develop tools that can measure progress on the contract's various clauses' -- source: https://yro.slashdot.org/story/19/11/25/1347233 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/

Zorin OS 15 Lite Linux Distro Can Rejuvenate Your Aging Windows PC
by Peter Reutemann 26 Nov '19

26 Nov '19

'Called "Zorin OS 15 Lite," it is not only lightweight, but thanks to the Xfce desktop environment and integrated Flatpak support, it should be quite familiar to those switching from Windows. In fact, the developers are intentionally targeting existing Windows 7 users, as Microsoft's operating system will be unsupported beginning January 2020. Zorin OS 15 Lite, in comparison, is based on Ubuntu 18.04 LTS and supported until 2023! It even comes with the very modern Linux kernel 5.0. "With Zorin OS 15 Lite, weâ(TM)ve condensed the full Zorin OS experience into a streamlined operating system, designed to run fast on computers as old as 15 years. With version 15, we've gone the extra mile to make the XFCE 4.14-based desktop feel familiar and user-friendly to new users, especially those moving away from Windows 7 leading up to the end of its support in January 2020. By pairing the most advanced and efficient software with a user-friendly experience, we've made it possible for anyone to extend the lifespan of their computers for years to come," explains the Zorin OS developers.' -- source: https://linux.slashdot.org/story/19/11/25/179256 Maybe worth a demo next year?

The RIPE NCC Has Run Out of IPv4 Addresses
by Peter Reutemann 26 Nov '19

26 Nov '19

'The RIPE NCC, the regional internet registry for Europe, West Asia, and the former USSR, has allocated the final /22 remaining in their address pool, and has stated that they have now run out of IPv4 addresses. RIPE will continue to recover IPv4 addresses from organisations that go out of business, close, or that return them due to lack of need, but expects these small amounts of recovered IPv4 addresses to fall well short of demand: RIPE will now only assign IPv4 addresses to entities that have never received any IPv4 allocation in the past, and even then will assign no more than a /24. RIPE puts out a call to action for IPv6 migration: This event is another step on the path towards global exhaustion of the remaining IPv4 addressing space. In recent years, we have seen the emergence of an IPv4 transfer market and greater use of Carrier Grade Network Address Translation (CGNAT) in our region. There are costs and trade-offs with both approaches and neither one solves the underlying problem, which is that there are not enough IPv4 addresses for everyone. Without wide-scale IPv6 deployment, we risk heading into a future where the growth of our Internet is unnecessarily limited — not by a lack of skilled network engineers, technical equipment or investment -- but by a shortage of unique network identifiers. There is still a long way to go, and we call on all stakeholders to play their role in supporting the IPv6 roll-out.' -- source: https://tech.slashdot.org/story/19/11/25/1841256 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/

NextCloud Linux Servers Targetted by NextCry Ransomware
by Peter Reutemann 25 Nov '19

25 Nov '19

'A new and particularly troublesome ransomware variant has been identified in the wild. Dubbed NextCry, this nasty strain of ransomware encrypts data on NextCloud Linux servers and has managed to evade the detection of public scanning platforms and antivirus engines. To make matters worse, there is currently no free decryption tool available for victims. Ransomware hunter and creator of ID Ransomware Michael Gillespie notes that the NextCry ransomware, which is a Python script compiled in a Linux ELF binary using pyInstaller, oddly uses Base64 to encode file names as well as the content of files which have already been encrypted. Gillespie has also confirmed that NextCry encrypts data using the AES algorithm with a 256-bit key. The ransom note that NextCry victims receive reads "READ_FOR_DECRYPT", and demands 0.025 BTC for a victim's files to be unlocked.' -- source: https://linux.slashdot.org/story/19/11/24/1845253 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 Tracking Prevention in Microsoft's Edge Will Hit Google the Hardest
by Peter Reutemann 25 Nov '19

25 Nov '19

'Microsoft's Edge browser is built on the same open source code as Google Chrome. But Ed Bott, writing for ZDNet, noticed something interesting: On January 15, 2020, Microsoft is scheduled to roll out a completely revamped Edge browser to the general public. That browser, which is available for beta testing now on all supported versions of Windows and MacOS, includes a feature called Tracking Prevention. If that name sounds familiar, you're not imagining things. Microsoft added a Tracking Protection feature to Internet Explorer 9, back in 2011; it used simple text files called Tracking Protection Lists (TPLs) to allow or block third-party requests from specific domains. That's the same general principle behind Tracking Prevention in the new Edge, but the implementation is more usable and more sophisticated, with multiple Trust Protection Lists taking the place of a single TPL. I've spent the past week looking closely at this feature... [A]lthough it's aimed at the online advertising and tracking industries in general, my tests suggest that its effects are likely to be felt most directly by one company: Google. Using the default Balanced setting, Tracking Prevention blocked a total of 2,318 trackers, or an average of 35 on each page. Of that total, 552 were from Google domains. That's a mind-boggling 23.8% of the total. To put that into perspective, the second entry on the list of blocked trackers was Facebook, which represented 3.8% of the total. Rather than an anti-Google conspiracy, the article suggests this is instead just a reflection of both Google's ubiquity and its business model. "Google Analytics and Google AdSense are embedded on a staggering number of web pages."' -- source: https://tech.slashdot.org/story/19/11/24/2055219 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Mint 19.2
by tom butz 23 Nov '19

23 Nov '19

Re: Linux Mint 19.2 The latest update ('new' package-manager) seems to disable Bluetooth. That also happened to me when I updated from 19.1 to 19.2 WITHOUT a complete reinstall. There are two workarounds: EITHER: back-up the whole system every night, and restore it if Bluetooth disappears again (=no icon in the panel after an update) - skipping updates. OR: use another system such as SparkyLinux, e.g. on a bootable sdcard for Bluetooth-transfers and stick with Mint 19.2 for anything else. I use this 'veteran' Linux because it features OpenShot 1.4 - my (favourite) moviemaker. My Toshiba laptop has 128 GB of RAM-HD, so copying/restoring to/from an image-file doesn't take all that long.

The Ad Tracker Arms Race Continues
by Lawrence D'Oliveiro 22 Nov '19

22 Nov '19

Web advertisers are resorting to a new technique <https://www.theregister.co.uk/2019/11/21/ublock_origin_firefox_unblockable_…> to bypass restrictions on third-party cookies for tracking users’ browsing behaviour: use first-party cookies instead. A detailed example can be found in this GitHub issue <https://github.com/uBlockOrigin/uBlock-issues/issues/780>: the site www.liberation.fr includes links to f7ds.liberation.fr, which is notionally under the same domain. However, that is actually a CNAME (alias) for the third-party tracker site liberation.eulerian.net. So cookies that are supposed to be restricted to *.liberation.fr are passed to that site as well. Just to be clear, this is not a browser “bug” by any means; it’s just part of how the DNS is supposed to work. The good news is, Firefox offers an API that adblocker addons can use to detect this sort of thing going on and stop it.

System76 Will Start Designing and Building Its Own Linux Laptops Beginning January 2020
by Peter Reutemann 21 Nov '19

21 Nov '19

'Denver-based PC manufacturer and Pop!_OS Linux developer System76 plans to follow-up its custom Thelio desktop PC with an in-house laptop beginning next year, according to founder and CEO Carl Richell. During a recent interview, Richell was quick to emphasize that the entire process of designing, prototyping and iterating the final product could take two to three years. But the company is eager to break into this market and put the same signature "stamp" on its laptop hardware that graces its custom-built Thelio desktop. System76 sells an extensive lineup of laptops, but the machines are designed by the likes of Sager and Clevo. The company doesn't merely buy a chassis and slap Pop!_OS on it, but Richell tells me he's confident that with the experience gained from developing Thelio -- and the recent investment into a factory at the company's Denver headquarters -- System76 is capable of building a laptop from the ground up that meets market needs and carries a unique value proposition. Richell says the company's first priority is locking down the aesthetic of the laptop and how various materials look and feel. It will simultaneously begin working on the supply chain aspects and speaking with various display and component manufacturers. System76 will design and build a U-class laptop first (basically an Ultrabook form factor like the existing Darter and Galago) and then evaluate what it might do with higher-end gaming and workstation notebooks with dedicated graphics.' -- source: https://hardware.slashdot.org/story/19/11/20/2241223 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/

“Where the Wi-Fi sucks” is where a new wireless protocol does its magic
by Peter Reutemann 21 Nov '19

21 Nov '19

'Researchers at Brigham Young University have created a new RF protocol that runs on top of existing consumer Wi-Fi at significantly greater range. But before you get too excited, the protocol's bandwidth is extremely low—so much so that it makes LoRa look like an OC-24. The protocol, called ONPC—short for On-Off Noise Power Communication—currently only specifies a single bit per second. Although ONPC only conveys one bit per second of data, its range is 60m or more beyond Wi-Fi—and it runs in software alone, on unmodified Wi-Fi hardware. An ONPC device can connect to standard Wi-Fi when range permits, fall back to ONPC mode if the connection drops, and then re-connect to the Wi-Fi when it becomes available again.' -- source: https://arstechnica.com/gadgets/2019/11/where-the-wi-fi-sucks-is-where-a-ne… 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 outlines plans for mainline Linux kernel support in Android
by Peter Reutemann 20 Nov '19

20 Nov '19

'It seems like Google is working hard to update and upstream the Linux kernel that sits at the heart of every Android phone. The company was a big participant in this year's Linux Plumbers Conference, a yearly meeting of the top Linux developers, and Google spent a lot of time talking about getting Android to work with a generic Linux kernel instead of the highly-customized version it uses now. It even showed an Android phone running a mainline Linux kernel. But first, some background on Android's current kernel mess.Currently, three major forks happen in between the "mainline" Linux kernel and a shipping Android device (note that "mainline" here has no relation to Google's own "Project Mainline"). First, Google takes the an LTS (Long Term Support) Linux kernel and turns it into the "Android Common kernel"—the Linux kernel with all the Android OS-specific patches applied. Android Common is shipped to the SoC vendor (usually Qualcomm) where it gets its first round of hardware-specific additions, first focusing on a particular model of SoC. This "SoC Kernel" then gets sent to a device manufacturer for even more hardware-specific code that supports every other piece of hardware, like the display, camera, speakers, usb ports, and any extra hardware. This is the "Device Kernel," and it's what actually ships on a device.' -- source: https://arstechnica.com/gadgets/2019/11/google-outlines-plans-for-mainline-… 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 and Samsung Fix Android Spying Flaw. Other Makers May Still Be Vulnerable
by Peter Reutemann 20 Nov '19

20 Nov '19

'Until recently, weaknesses in Android camera apps from Google and Samsung made it possible for rogue apps to record video and audio and take images and then upload them to an attacker-controlled server -- without any permissions to do so. Camera apps from other manufacturers may still be susceptible. From a report: The weakness, which was discovered by researchers from security firm Checkmarx, represented a potential privacy risk to high-value targets, such as those preyed upon by nation-sponsored spies. Google carefully designed its Android operating system to bar apps from accessing cameras and microphones without explicit permission from end users. An investigation published Tuesday showed it was trivial to bypass those restrictions. The investigation found that an app needed no permissions at all to cause the camera to shoot pictures and record video and audio. To upload the images and video -- or any other image and video stored on the phone -- to an attacker-controlled server, an app needed only permission to access storage, which is among one of the most commonly given usage rights. The weakness, which is tracked as CVE-2019-2234, also allowed would-be attackers to track the physical location of the device, assuming GPS data was embedded into images or videos. Google closed the eavesdropping hole in its Pixel line of devices with a camera update that became available in July. Checkmarx said Samsung has also fixed the vulnerability, although it wasn't clear when that happened. Checkmarx said Google has indicated that Android phones from other manufacturers may also be vulnerable. The specific makers and models haven't been disclosed.' -- source: https://tech.slashdot.org/story/19/11/19/1737219 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 World's Fastest Supercomputers Hit Higher Speeds Than Ever With Linux
by Peter Reutemann 19 Nov '19

19 Nov '19

'In the latest Top 500 supercomputer ratings, the average speed of these Linux-powered racers is now an astonishing 1.14 petaflops. The fastest of the fast machines haven't changed since the June 2019 Top 500 supercomputer list. Leading the way is Oak Ridge National Laboratory's Summit system, which holds top honors with an HPL result of 148.6 petaflops. This is an IBM-built supercomputer using Power9 CPUs and NVIDIA Tesla V100 GPUs. In a rather distant second place is another IBM machine: Lawrence Livermore National Laboratory's Sierra system. It uses the same chips, but it "only" hit a speed of 94.6 petaflops. Close behind at No. 3 is the Sunway TaihuLight supercomputer, with an HPL mark of 93.0 petaflops. TaihuLight was developed by China's National Research Center of Parallel Computer Engineering and Technology (NRCPC) and is installed at the National Supercomputing Center in Wuxi. It is powered exclusively by Sunway's SW26010 processors. Sunway's followed by the Tianhe-2A (Milky Way-2A). This is a system developed by China's National University of Defense Technology (NUDT). It's deployed at the National Supercomputer Center in China. Powered by Intel Xeon CPUs and Matrix-2000 accelerators, it has a top speed of 61.4 petaflops. Coming at No. 5, the Dell-built, Frontera, a Dell C6420 system is powered by Intel Xeon Platinum processors. It speeds along at 23.5 petaflops. It lives at the Texas Advanced Computing Center of the University of Texas. The most powerful new supercomputer on the list is Rensselaer Polytechnic Institute Center for Computational Innovations (CCI)'s AiMOS. It made the list in the 25th position with 8.0 petaflops.

Intel To Remove Old Drivers and BIOS Updates From Its Site
by Peter Reutemann 19 Nov '19

19 Nov '19

'By Friday this week, Intel plans to remove old drivers and BIOS updates from its official website. From a report: "This download, BIOS Update [BLH6710H.86A] 0163, will no longer be available after November 22, 2019 and will not be supported with any additional functional, security, or other updates," reads a message posted to the download page of one of the impacted components. "Intel recommends that users of BIOS Update [BLH6710H.86A] 0163 uninstall and/or discontinue use as soon as possible," the message continues. The downloads are drivers and BIOS updates for Intel desktop components and motherboards the company released in the 90s and early-to-mid 2000s.

Microsoft Announces Plan To Support DoH In Windows
by Peter Reutemann 19 Nov '19

19 Nov '19

'Microsoft's Core Network team just announced they plan on supporting DoH in the Windows resolver. In the blog post, the company writes: Providing encrypted DNS support without breaking existing Windows device admin configuration won't be easy. However, at Microsoft we believe that "we have to treat privacy as a human right. We have to have end-to-end cybersecurity built into technology." We also believe Windows adoption of encrypted DNS will help make the overall Internet ecosystem healthier. There is an assumption by many that DNS encryption requires DNS centralization. This is only true if encrypted DNS adoption isn't universal. To keep the DNS decentralized, it will be important for client operating systems (such as Windows) and Internet service providers alike to widely adopt encrypted DNS. With the decision made to build support for encrypted DNS, the next step is to figure out what kind of DNS encryption Windows will support and how it will be configured. Here are our team's guiding principles on making those decisions: Windows DNS needs to be as private and functional as possible by default without the need for user or admin configuration because Windows DNS traffic represents a snapshot of the user's browsing history. To Windows users, this means their experience will be made as private as possible by Windows out of the box. For Microsoft, this means we will look for opportunities to encrypt Windows DNS traffic without changing the configured DNS resolvers set by users and system administrators. Privacy-minded Windows users and administrators need to be guided to DNS settings even if they don't know what DNS is yet. Many users are interested in controlling their privacy and go looking for privacy-centric settings such as app permissions to camera and location but may not be aware of or know about DNS settings or understand why they matter and may not look for them in the device settings. Windows users and administrators need to be able to improve their DNS configuration with as few simple actions as possible. We must ensure we don't require specialized knowledge or effort on the part of Windows users to benefit from encrypted DNS. Enterprise policies and UI actions alike should be something you only have to do once rather than need to maintain. Windows users and administrators need to explicitly allow fallback from encrypted DNS once configured. Once Windows has been configured to use encrypted DNS, if it gets no other instructions from Windows users or administrators, it should assume falling back to unencrypted DNS is forbidden.' -- source: https://yro.slashdot.org/story/19/11/18/1929229 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/

Why Firefox Fights for the Future of the Web
by Peter Reutemann 18 Nov '19

18 Nov '19

'"Mozilla is no longer fighting for market share of its browser: it is fighting for the future of the web," writes the Guardian, citing Mozilla Project co-founder Mitchell Baker: Baker's pitch is that only Mozilla is motivated, first and foremost, to make using the web a pleasurable experience. Google's main priority is to funnel user data into the enormous advertising engine that accounts for most of its revenue. Apple's motivation is to ensure that customers continue to buy a new iPhone every couple of years and don't switch to Android...." Firefox now runs sites such as Facebook in "containers", effectively hiving the social network off into its own little sandboxed world, where it can't see what's happening on other sites. Baker says: "It reduces Facebook's ability to follow you around the web and track you when you're not on Facebook and just living your life...." Mozilla has launched Monitor, a data-breach reporting service; Lockwise, a password manager; and Send, a privacy-focused alternative to services such as WeSendit. It's also beta-testing a VPN (virtual private network) service, which it hopes to market to privacy-conscious users... Apple's iOS (mobile operating system) is an acknowledged disaster for Mozilla. Safari is the default and, while users can install other browsers, they come doubly hindered: they can never be set as the default, meaning any link clicked in other applications will open in Safari; and they must use Safari's "rendering engine", a technical limitation that means that even the browsers that Firefox does have on the platform are technically just fancy wrappers for Apple's own browser, rather than full versions of the service that Mozilla has built over the decades... "Even if you do download a replacement, iOS drops you back into the default. I don't know why that's acceptable. Every link you open on a phone is the choice of the phone maker, even if you, as a user, want something else." Summarizing Baker's concerns, the Guardian writes that "It is perfectly possible to build a browser that prevents advertising companies from aggregating user data. But it is unlikely that any browser made by an advertising company would offer such a feature..." And an activist for the Small Technology Foundation tells them that Google "wants the web to go through Google. It already mostly does: with eyes on 70% to 80% of the web."' -- source: https://news.slashdot.org/story/19/11/17/1614222 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/

Wikipedia's Co-Founder Takes On Facebook With Ad-Free Social Network
by Peter Reutemann 15 Nov '19

15 Nov '19

'Wikipedia co-founder Jimmy Wales has launched a social network called WT:Social. It has no financial association with Wikipedia and operates on donations, not advertising. The Next Web reports: WT:Social went live last month and is currently nearing 50,000 users. The company is rolling out access slowly; when I signed up, I was approximately number 28,000 on the waitlist. Alternatively, you can pay 13 bucks a month or 100 a year to get access right away. In comments to the Financial Times, Wales said "The business model of social media companies, of pure advertising, is problematic. It turns out the huge winner is low-quality content." You don't say. WT:Social's interface is rather sparse at the moment, featuring a simple feed comprised of news stories and comments below them. News is a big part of the network; it's a spinoff of Wales' previous project, WikiTribune, which sought to be a global news site comprised of professional journalists and citizen contributors. Both WikiTribune and WT:Social emphasize combatting fake news, highlighting evidence-based coverage over the focus on "engagement" seen on other networks. Each story posted to the network makes prominent where the article comes from, as well as sources and references. You can also join various "SubWikis" that are essentially like Facebook groups or subreddits, which filter content to stories of a given topic. You can also add hashtags to a post or follow hashtags for more specific interests that might span more than one SubWiki. Posts are currently sorted chronologically, but the site plans to add an upvote system for users to promote quality stories.' -- source: https://news.slashdot.org/story/19/11/14/223256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Windows and Linux Get Options To Disable Intel TSX To Prevent Zombieload v2 Attacks
by Peter Reutemann 15 Nov '19

15 Nov '19

'Both Microsoft and the Linux kernel teams have added ways to disable support for Intel Transactional Synchronization Extensions (TSX). From a report: TSX is the Intel technology that opens the company's CPUs to attacks via the Zombieload v2 vulnerability. Zombieload v2 is the codename of a vulnerability that allows malware or a malicious threat actor to extract information processed inside a CPU, information to which they normally shouldn't be able to access due to the security walls present inside modern-day CPUs. This new vulnerability was disclosed earlier this week. Intel said it would release microcode (CPU firmware) updates -- available on the company's Support & Downloads center. But, the reality of a real-world production environment is that performance matters. Past microcode updates for other attacks, such as Meltdown, Spectre, Foreshadow, Fallout, and Zombieload v1, have been known to introduce performance hits of up to 40%. Seeing that all the CPU attacks listed above are not only theoretical but also hard to pull off, some companies don't see this performance hit as an option.' -- source: https://tech.slashdot.org/story/19/11/14/1654247 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/

GitHub Places Open-Source Code In Arctic Cave For Safekeeping
by Peter Reutemann 14 Nov '19

14 Nov '19

'GitHub's CEO Nat Friedman traveled to Svalbard in October to stash Linux, Android, and 6,000 other open-source projects in a permafrost-filled, abandoned coal mine. It's part of a project to safeguard the world's software from existential threats and also just to archive the code for posterity. As Friedman says, "If you told someone 20 years ago that in 2020, all of human civilization will depend on and run on open-source code written for free by volunteers in countries all around the world who don't know each other, and it'll just be downloaded and put into almost every product, I think people would say, 'That's crazy, that's never going to happen. Software is written by big, professional companies.' It's sort of a magical moment. Having a historical record of this will, I think, be valuable to future generations." GitHub plans to open several more vaults in other places around the world and to store any code that people want included.' -- source: https://news.slashdot.org/story/19/11/13/2155230 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/

Mozilla, Intel, and More Form the Bytecode Alliance To Take WebAssembly Beyond Browsers
by Peter Reutemann 14 Nov '19

14 Nov '19

'Mozilla has been heavily invested in WebAssembly with Firefox, and today, the organization teamed up with a few others to form the new Bytecode Alliance, which aims to create "new software foundations, building on standards such as WebAssembly and WebAssembly System Interface (WASI)." Mozilla has teamed up with Intel, Red Hat, and Fastly to found the alliance, but more members are likely to join over time. The goal of the Bytecode Alliance is to create a new runtime environment and language toolchains which are secure, efficient, and modular, while also being available on as many platforms and devices as possible. The technologies being developed by the Bytecode Alliance are based on WebAssembly and WASI, which have been seen as a potential replacement for JavaScript due to more efficient code compiling, and the expanded capabilities of being able to port C and C++ code to the web. To kick things off, the founding members have already contributed a number of open-source technologies to the Bytecode Alliance, including Wasmtime, a lightweight WebAssembly runtime; Lucet, an ahead-of-time compiler; WebAssembly Micro Runtime; and Cranelift.' -- source: https://news.slashdot.org/story/19/11/13/1750234 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/

TPM-FAIL Vulnerabilities Impact TPM Chips In Desktops, Laptops, Servers
by Peter Reutemann 14 Nov '19

14 Nov '19

'A team of academics has disclosed today two vulnerabilities known collectively as TPM-FAIL that could allow an attacker to retrieve cryptographic keys stored inside TPMs. The first vulnerability is CVE-2019-11090 and impacts Intel's Platform Trust Technology (PTT). Intel PTT is Intel's fTPM software-based TPM solution and is widely used on servers, desktops, and laptops, being supported on all Intel CPUs released since 2013, starting with the Haswell generation. The second is CVE-2019-16863 and impacts the ST33 TPM chip made by STMicroelectronics. This chip is incredibly popular and is used on a wide array of devices ranging from networking equipment to cloud servers, being one of the few chips that received a CommonCriteria (CC) EAL 4+ classification — which implies it comes with built-in protection against side-channel attacks like the ones discovered by the research team. Unlike most TPM attacks, these ones were deemed practical. A local adversary can recover the ECDSA key from Intel fTPM in 4-20 minutes depending on the access level. We even show that these attacks can be performed remotely on fast networks, by recovering the authentication key of a virtual private network (VPN) server in 5 hou' -- source: https://it.slashdot.org/story/19/11/13/1837225 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/

'When you're scrolling through Facebook's app, the social network could be watching you back, in more ways than just your data, concerned users have found. Multiple people have found and reported that their iPhone cameras were turned on in the background while looking at their feed. From a report: The issue came to light with several posts on Twitter, showing that their cameras were activated behind Facebook's app as they were watching videos or looking at photos on the social network. After clicking on the video to full screen, returning it back to normal would create a bug where Facebook's mobile layout was slightly shifted to the right. With the open space on the left, you could now see the phone's camera activated in the background. This was documented in multiple cases, with the earliest incident on November 2.' -- source: https://tech.slashdot.org/story/19/11/12/1630204 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/

As 5G Rolls Out, Troubling New Security Flaws Emerge
by Peter Reutemann 13 Nov '19

13 Nov '19

'It's not yet prime time for 5G networks, which still face logistical and technical hurdles, but they're increasingly coming online in major cities worldwide. Which is why it's especially worrying that new 5G vulnerabilities are being discovered almost by the dozen. From a report: At the Association for Computing Machinery's Conference on Computer and Communications Security in London today researchers are presenting new findings that the 5G specification still has vulnerabilities. And with 5G increasingly becoming a reality, time is running out to catch these flaws. The researchers from Purdue University and the University of Iowa are detailing 11 new design issues in 5G protocols that could expose your location, downgrade your service to old mobile data networks, run up your wireless bills, or even track when you make calls, text, or browse the web. They also found five additional 5G vulnerabilities that carried over from 3G and 4G. They identified all of those flaws with a new custom tool called 5GReasoner. One purported benefit of 5G is that it protects phone identifiers, like your device's "international mobile subscriber identity," to help prevent tracking or targeted attacks. But downgrade attacks like the ones the researchers found can bump your device down to 4G, or put it into limited service mode, then force it to send its IMSI number unencrypted. Increasingly, networks use an alternative ID called a Temporary Mobile Subscriber Identity that refreshes periodically to stymie tracking. But the researchers also found flaws that could allow them to override TMSI resets, or correlate a device's old and new TMSI, to track devices. Mounting those attacks takes only software-defined radios that cost a few hundred dollars. The 5GReasoner tool also found issues with the part of the 5G standard that governs things like initial device registration, deregistration, and paging, which notifies your phone about incoming calls and texts. Depending on how a carrier implements the standard, attackers could mount "replay" attacks to run up a target's mobile bill by repeatedly sending the same message or command. It's an instance of vague wording in the 5G standard that could cause carriers to implement it weakly.' -- source: https://tech.slashdot.org/story/19/11/12/1845229 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/

Intel's Cascade Lake CPUs Impacted By New Zombieload v2 Attack

13 Nov '19

'The Zombieload vulnerability disclosed earlier this year in May has a second variant that also works against more recent Intel processors, not just older ones, including Cascade Lake, Intel's latest line of high-end CPUs -- initially thought to have been unaffected. From a report: Intel is releasing microcode (CPU firmware) updates today to address this new Zombieload attack variant, as part of its monthly Patch Tuesday -- known as the Intel Platform Update (IPU) process. Back in May, two teams of academics disclosed a new batch of vulnerabilities that impacted Intel CPUs. Collectively known as MDS attacks, these are security flaws in the same class as Meltdown, Spectre, and Foreshadow. The attacks rely on taking advantage of the speculative execution process, which is an optimization technique that Intel added to its CPUs to improve data processing speeds and performance. Vulnerabilities like Meltdown, Spectre, and Foreshadow, showed that the speculative execution process was riddled with security holes. Disclosed in May, MDS attacks were just the latest line of vulnerabilities impacting speculative execution. They were different from the original Meltdown, Spectre, and Foreshadow bugs disclosed in 2018 because they attacked different areas of a CPU's speculative execution process.' -- source: https://hardware.slashdot.org/story/19/11/12/1924232 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/

Reactions To the News That Microsoft's Edge Browser Is Coming to Linux
by Peter Reutemann 11 Nov '19

11 Nov '19

'"Microsoft is bringing Edge to Linux, for all the Microsoft fans running Linux," jokes the headline at the Inquirer. ("We can just imagine the amount of bunting and party poppers that the Linux community has just ordered. After all, why wouldn't you want a browser from the company that you joined Linux to get away from?") And the headline at Liliputting quips that the Edge browser "is coming to Linux (whether you want it or not)," calling the move "the latest evidence that Microsoft's relationship to Linux has changed a lot in recent years. But TechRadar had an even more sardonic headline. "Hell freezes over as Microsoft Edge comes to Linux." One other thing to consider is that the introduction of Edge to Linux is something of a thorny subject in that the folks who choose a Linux distro often do so to break away from the chains of Microsoft and Windows (or indeed Apple). So certainly some of the more fervent open source types out there may not welcome a Microsoft browser with open arms, and doubtless it will be regarded with suspicion in some quarters. No matter how much Microsoft has been banging the open source drum in many different ways in recent times. That said, there will doubtless be Linux users who are curious, and may want to pick up a mainstream alternative to Firefox on Linux which, when compared to Chrome -- with its famous memory hogging antics -- makes a far preferable choice in some respects. Edge will also do streaming better (by default Chrome limits you to 720p when you're trying to watch a spot of Netflix). All the testing feedback about Edge has been pretty positive in the main thus far, too, so maybe that will persuade even doubters to at least consider it. One thing's for sure: it will certainly be interesting to see the reaction Microsoft's browser gets when it is deployed to Linux. Edge may face a rocky reception. "I am not feeling a tingling all over at the thought of Edge coming to Linux," posted one commenter on Beta News. "It's not really necessary to bring Linux down to the level of Windows 10."' -- source: https://linux.slashdot.org/story/19/11/11/0249222 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/

uBlock on Firefox 70.0.1 - memory hungry?
by Peter Reutemann 11 Nov '19

11 Nov '19

Hi everyone Since the last Firefox update to 70.0.1, I noticed that my Firefox was getting sluggish, sometimes taking several seconds before finishing rendering a page and allowing me to click on links. After looking in the processes, turns out that WebExtensions was gobbling up nearly 21GB, not to mention several other processes for rendering the tabs! It was probably swapping memory all the time... After turning off my uBlock addon (and restarting the browser, of course), Firefox is now as responsive as I was used to and WebExtensions is now ~2.5GB. Not sure whether this is due to the newly introduced privacy protection facility within core Firefox, that uBlock ballooned/slowed down like that. Anyway, still got my NoScript and PrivacyBadger addons active.

Are Forced Subscriptions Driving 3D Users To Open Source Tools?
by Peter Reutemann 11 Nov '19

11 Nov '19

'Slashdot reader dryriver writes: More and more professional 3D software like 3DMax, Maya, AutoCAD (Autodesk) and Substance Painter (Adobe) is now only available on a monthly or yearly subscription basis — you cannot buy any kind of perpetual license for these industry standard 3D tools anymore, cannot offline install or activate the tools, and the tools also phone home every few days over the internet to see whether you have "paid your rent". Stop paying your rent, and the software shuts down, leaving you unable to even look at any 3D project files you may have created with software. This has caused so much frustration, concern and anxiety among 3D content creators that, increasingly, everybody is trying to replace their commercial 3D software with Open Source 3D tools. Thankfully, open source 3D tools have grown up nicely in recent years. Some of the most popular FOSS 3D tools are the complete 3D suite Blender, polygon modeling tool Wings 3D, polygon modeling tool Dust3D, CAD modeling tool FreeCAD, PBR texturing tool ArmorPaint, procedural materials generator Material Maker, image editing tool GIMP, painting tool Krita, vector illustration tool Inkscape and the 2D/3D game engine Godot Engine. Along with these tools comes a beguiling possibility — while working with commercial 3D tools pretty much forced you to use Windows X in terms of OS choice in the past, all of the FOSS 3D tool alternatives have Linux versions. This means that for the first time, professional 3D users can give Windows a miss and work with Linux as their OS instead. In a comment on the original submission, dryriver offers some anecdotal evidence: Go on any major 3D software forum on the Internet and it is filled with enraged 3D users revolting against forced software subscriptions and threatening to switch to FOSS Blender as soon as possible. Some major 3D animation studios are also working Blender into their CGI pipeline. Companies like EPIC and Nvidia have begun donating to the Blender foundation. Its happening. The move away from commercial closed source tools - which are expensive, stagnant and don't offer you permanent licenses anymore - is in full swing. The fact that Blender has an innovative GPU accelerated realtime render engine called EEVEE that none of the commercial software has has only accelerated this trend. Blender is widely believed to have 2 - 3 million active users already, and the fact that V 2.80 comes with a much more usable UI is only accelerating things.' -- source: https://news.slashdot.org/story/19/11/09/064248 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/

DNS-over-HTTPS Will Eventually Roll Out in All Major Browsers, Despite ISP Opposition
by Peter Reutemann 09 Nov '19

09 Nov '19

' All major browsers -- including Chrome, Firefox, Safari, Opera, Microsoft Edge, Vivaldi, Brave -- have plans to support DNS-over-HTTPS (or DoH), a protocol that encrypts DNS traffic and helps improve a user's privacy on the web. From a report: The DoH protocol has been one of the year's hot topics. It's a protocol that, when deployed inside a browser, it allows the browser to hide DNS requests and responses inside regular-looking HTTPS traffic. Doing this makes a user's DNS traffic invisible to third-party network observers, such as ISPs. But while users love DoH and have deemed it a privacy boon, ISPs, networking operators, and cyber-security vendors hate it. A UK ISP called Mozilla an "internet villain" for its plans to roll out DoH, and a Comcast-backed lobby group has been caught preparing a misleading document about DoH that they were planning to present to US lawmakers in the hopes of preventing DoH's broader rollout. However, this may be a little too late. ZDNet has spent the week reaching out to major web browser providers to gauge their future plans regarding DoH, and all vendors plan to ship it, in one form or another.' -- source: https://it.slashdot.org/story/19/11/08/189243 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 Turns 15
by Peter Reutemann 09 Nov '19

09 Nov '19

'On November 9 2004, a new version of Mozilla's browser called Firefox shipped. It was taking on one of the most daunting monopolies in tech: Microsoft's Internet Explorer, which had more than 90 percent market share. But Firefox was really good, and it became an instant hit, ending Microsoft's dominance of the web. Over at Fast Company, Sean Captain took a look at the browser's original rise, the challenges it faced after Google's Chrome arrived on the scene, and the moves it's currently making to put user privacy first.' -- source: https://news.slashdot.org/story/19/11/08/162243 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/

GitLab Director Resigns, Says It's Engaging In 'Retaliatory Behavior'
by Peter Reutemann 09 Nov '19

09 Nov '19

'Candice Ciresi, GitLab's director of risk and global compliance, has resigned after less than six months on the job, apparently saying that the $2.75 billion startup is "engaging in discriminatory and retaliatory behavior." Business Insider reports: Notably, Ciresi resigned in public: GitLab espouses a culture of transparency, whereby all major product and corporate policy decisions are announced and discussed where anybody can see. She posted her resignation in response to one such discussion -- an active debate over a proposed GitLab policy, in which it would ban the hiring of people who live in China or Russia for any role that would require access to customer data. At the time of writing, Ciresi's post announcing her resignation had been reviewed and then "redacted" by GitLab, citing concerns that it would "further inflame this situation." However, Ciresi's comment went out via email to GitLab users who had subscribed to this particular discussion. Per a screenshot posted to Reddit, Ciresi wrote: "As I believe GitLab is engaging in discriminatory and retaliatory behavior, I have tendered my resignation." "We did decide to moderate this post for review, as there have already been credible personal and physical threats against GitLab employees in this issue thread," GitLab says, in part, in place of Ciresi's comment. "While this particular post did not contain a personal threat to anyone, we were concerned it would further inflame this situation." GitLab confirmed Ciresi's departure but didn't comment any further' -- source: https://developers.slashdot.org/story/19/11/08/2216219 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/

Chrome OS 78 Rolling Out With Picture-In-Picture Support For YouTube, Split Browser/Device Settings, More
by Peter Reutemann 08 Nov '19

08 Nov '19

'The latest version of Chrome OS, version 78, adds separate browser and device settings, click-to-call, and picture-in-picture support for YouTube. It also introduces virtual desktop support for the operating system with a feature called Virtual Desks. 9to5Google reports: Chrome is getting another cross-device sharing feature after "Send this page" widely rolled in September. With "click-to-call," you can right-click on phone number links -- like tel:800-800-8000 -- to have them sent to your Android device. It's quicker than manually entering those digits or transferring via email. Chrome OS 78 will separate browser and device settings. The former is accessible directly at chrome://settings and what opens when clicking "Settings" at the bottom of the Overflow menu in the top-right corner of any browser window. It opens as a tab and provides web-related preferences. Meanwhile, chrome://os-settings opens as its own window, and can be accessed from the quick settings sheet. It provides device options like Wi-Fi, Bluetooth, and Assistant in a white Material Theme UI with an icon in the launcher/app shelf. YouTube for Android now supports picture-in-picture with Chrome OS 78. After starting a video in the mobile client, switching to another window, covering, or minimizing the app will automatically open a PiP in the bottom-right corner. Available controls include switching to audio, play/pause, and skipping to the next track. In the top-left, you can expand the window and a settings gear on the other side allows you to open system settings. Tapping in the center expands and returns you to the YouTube Android app. Chrome OS 78 simplifies the printing experience by automatically listing compatible printers without any prior setup required. There are also a number of Linux on Chrome OS enhancements in this version: - Backups of Linux apps and files can now be saved to local storage, external drive, or Google Drive. That copy can be then restored when setting up a new computer. - Crostini GPU support will be enabled by default for a "crisp, lower-latency experience." - You'll be warned when using a Linux app that does not support virtual keyboard in tablet mode.' -- source: https://linux.slashdot.org/story/19/11/07/2341228 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/

Amazon Ring Doorbells Exposed Home Wi-Fi Passwords To Hackers
by Peter Reutemann 08 Nov '19

08 Nov '19

'Security researchers have discovered a vulnerability in Ring doorbells that exposed the passwords for the Wi-Fi networks to which they were connected. Bitdefender said the Amazon-owned doorbell was sending owners' Wi-Fi passwords in cleartext as the doorbell joins the local network, allowing nearby hackers to intercept the Wi-Fi password and gain access to the network to launch larger attacks or conduct surveillance. "When first configuring the device, the smartphone app must send the wireless network credentials. This takes place in an unsecure manner, through an unprotected access point," said Bitdefender. "Once this network is up, the app connects to it automatically, queries the device, then sends the credentials to the local network." But all of this is carried out over an unencrypted connection, exposing the Wi-Fi password that is sent over the air. Amazon fixed the vulnerability in all Ring devices in September, but the vulnerability was only disclosed today.' -- source: https://mobile.slashdot.org/story/19/11/07/2125208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft’s Project Silica offers robust thousand-year storage
by Peter Reutemann 08 Nov '19

08 Nov '19

Not strictly Linux or open source related, but I wouldn't mind having a backup that lasts longer than just a few years! 'Ars spoke Tuesday with Dr. Ant Rowstron, a principal researcher at Microsoft Research in Cambridge, UK, about an innovative cold storage project called Silica. Silica aims to replace both tape and optical archival discs as the media of choice for large-scale, (very) long duration cold storage. Microsoft Research is partnering with film giant Warner Bros., which is directly interested in reducing costs and increasing reliability in its own cold storage programs. The medium in question is a block of high-purity glass, which has voxels etched into it with femtosecond lasers. Each voxel stores multiple bits in two properties, retardance and angle, which may in turn be read using microscope imaging and polarized light. Voxels may be written 100 or more layers deep in a 2mm-deep piece of glass, by focusing the laser to the desired depth within the block itself. The speed of both reads and writes to Silica currently leave something to be desired—it took approximately a week to etch Superman's roughly 76GB of data last year, and Rowstron estimates it would take about three days to re-read the data, with advances made since. The technology is still in its infancy, of course, and large decreases in time required for both writing and reading are expected moving forward. Rowstron says he still doesn't expect anyone is likely to try to actually play Superman directly from its Silica record—but that's not what it's intended for.' -- source: https://arstechnica.com/gadgets/2019/11/microsofts-project-silica-offers-ro… 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 Original Google Pixel Will Get One Final Update In December
by Peter Reutemann 06 Nov '19

06 Nov '19

'Google has confirmed to The Verge that it will release "one final software update" next month for the original Google Pixel and Pixel XL. From the report: As of yesterday, it looked like the original Pixel was done getting updates, as Google released its November security update for most Pixel phones, but nothing for the Pixel or Pixel XL. Google tells The Verge that the Pixels won't get that November update, but it says December's "encapsulates a variety of updates" from the November and December updates that were issued for other Pixels. It wasn't too surprising to see that Google's original Pixels didn't get yesterday's update. When Google announced the phones in 2016, the company said they would get two years of guaranteed Android version updates and three years of security updates, which is also reflected on Google's support page. That said, Google surprised Pixel owners earlier this year by letting them run Android 10, which is one more year of Android than Google originally promised, and now, they have one final update to look forward to as well.

Android Bug Lets Hackers Plant Malware Via NFC Beaming
by Peter Reutemann 05 Nov '19

05 Nov '19

'Google patched last month an Android bug that can let hackers spread malware to a nearby phone via a little-known Android OS feature called NFC beaming. NFC beaming works via an internal Android OS service known as Android Beam. This service allows an Android device to send data such as images, files, videos, or even apps, to another nearby device using NFC (Near-Field Communication) radio waves, as an alternative to WiFi or Bluetooth. Typically, apps (APK files) sent via NFC beaming are stored on disk and a notification is shown on screen. The notification asks the device owner if he wants to allow the NFC service to install an app from an unknown source. But, in January this year, a security researcher named Y. Shafranovich discovered that apps sent via NFC beaming on Android 8 (Oreo) or later versions would not show this prompt. Instead, the notification would allow the user to install the app with one tap, without any security warning. The CVE-2019-2114 bug resided in the fact that the Android Beam app was also whitelisted, receiving the same level of trust as the official Play Store app. Google said this wasn't meant to happen, as the Android Beam service was never meant as a way to install applications, but merely as a way to transfer data from device to device. The October 2019 Android patches removed the Android Beam service from the OS whitelist of trusted sources. However, many millions of users remain at risk. If users have the NFC service and the Android Beam service enabled, a nearby attacker could plant malware (malicious apps) on their phones. Since most newly-sold devices have the NFC feature enabled by default, you'll have to disable Android Beam and NFC or update your phone to receive the October 2019 security updates if you want to protect yourself from this bug.' -- source: https://it.slashdot.org/story/19/11/04/216228 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/

Researchers hack Siri, Alexa, and Google Home by shining lasers at them
by Peter Reutemann 05 Nov '19

05 Nov '19

'Siri, Alexa, and Google Assistant are vulnerable to attacks that use lasers to inject inaudible—and sometimes invisible—commands into the devices and surreptitiously cause them to unlock doors, visit websites, and locate, unlock, and start vehicles, researchers report in a research paper published on Monday. Dubbed Light Commands, the attack works against Facebook Portal and a variety of phones. Shining a low-powered laser into these voice-activated systems allows attackers to inject commands of their choice from as far away as 360 feet (110m). Because voice-controlled systems often don’t require users to authenticate themselves, the attack can frequently be carried out without the need of a password or PIN. Even when the systems require authentication for certain actions, it may be feasible to brute force the PIN, since many devices don’t limit the number of guesses a user can make. Among other things, light-based commands can be sent from one building to another and penetrate glass when a vulnerable device is kept near a closed window. The attack exploits a vulnerability in microphones that use micro-electro-mechanical systems, or MEMS. The microscopic MEMS components of these microphones unintentionally respond to light as if it were sound. While the researchers tested only Siri, Alexa, Google Assistant, Facebook Portal, and a small number of tablets and phones, the researchers believe all devices that use MEMS microphones are susceptible to Light Commands attacks.' -- source: https://arstechnica.com/information-technology/2019/11/researchers-hack-sir… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Linus Torvalds: 'I'm Not a Programmer Anymore'

'Linus Torvalds, Linux's creator, doesn't make speeches anymore. But, what he does do, and he did again at Open Source Summit Europe in Lyon France is have public conversations with his friend Dirk Hohndel, VMware's Chief Open Source Officer. In this keynote discussion, Torvalds revealed that he doesn't think he's a programmer anymore. So what does the person everyone thinks of as a programmer's programmer do instead? Torvalds explained: "I don't know coding at all anymore. Most of the code I write is in my e-mails. So somebody sends me a patch ... I [reply with] pseudo code. I'm so used to editing patches now I sometimes edit patches and send out the patch without having ever tested it. I literally wrote it in the mail and say, 'I think this is how it should be done,' but this is what I do, I am not a programmer." So, Hohndel asked, "What is your job?" Torvalds replied, "I read and write a lot of email. My job really is, in the end, is to say 'no.' Somebody has to say 'no' to [this patch or that pull request]. And because developers know that if they do something that I'll say 'no' to, they do a better job of writing the code."' -- source: https://linux.slashdot.org/story/19/11/03/2230223 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 To Hide Notification Popups By Default Starting Next Year
by Peter Reutemann 04 Nov '19

04 Nov '19

'In a move to fight spam and improve the health of the web, Firefox will hide those annoying notification popups by default starting next year, with the release of Firefox 72, in January 2020, ZDNet has learned from a Mozilla engineer. The move comes after Mozilla ran an experiment back in April this year to see how users interacted with notifications, and also looked at different ways of blocking notifications from being too intrusive. Usage stats showed that the vast majority (97%) of Firefox users dismissed notifications, or chose to block a website from showing notifications at all... As a result, Mozilla engineers have decided to hide the notification popup that drops down from Firefox's URL bar, starting with Firefox 72. If a website shows a notification, the popup will be hidden by default, and an icon added to the URL bar instead. Firefox will then animate the icon using a wiggle effect to let the user know there's a notification subscription popup available, but the popup won't be displayed until the user clicks the icon. Mozilla is the first browser vendor to block notification popups by default, according to the article. It's already available in Firefox Nightly versions, but will be added to the stable branch in January. "I think Mozilla's decision is good for the health of the web," Jérôme Segura, malware analyst at Malwarebytes tells ZDNet.' -- source: https://news.slashdot.org/story/19/11/03/1646236 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/

Does Linux Have a Marketing Problem?
by Peter Reutemann 04 Nov '19

04 Nov '19

'On Hackaday's hosting site Hackaday.io, an electrical engineer with a background in semiconductor physics argues that Linux's small market share is due to a lack of marketing: Not only does [Linux] have dominance when raw computing ability is needed, either in a supercomputer or a webserver, but it must have some ability to effectively work as a personal computer as well, otherwise Android wouldn't be so popular on smartphones and tablets. >From there it follows that the only reason that Microsoft and Apple dominate the desktop world is because they have a marketing group behind their products, which provides customers with a comfortable customer service layer between themselves and the engineers and programmers at those companies, and also drowns out the message that Linux even exists in the personal computing realm... Part of the problem too is that Linux and most of its associated software is free and open source. What is often a strength when it comes to the quality of software and its flexibility and customizablity becomes a weakness when there's no revenue coming in to actually fund a marketing group that would be able to address this core communications issue between potential future users and the creators of the software. Canonical, Red Hat, SUSE and others all had varying successes, but this illistrates another problem: the splintered nature of open-source software causes a fragmenting not just in the software itself but the resources. Imagine if there were hundreds of different versions of macOS that all Apple users had to learn about and then decide which one was the best for their needs... I have been using Linux exclusively since I ditched XP for 5.10 Breezy Badger and would love to live in a world where I'm not forced into the corporate hellscape of a Windows environment every day for no other reason than most people already know how to use Windows. With a cohesive marketing strategy, I think this could become a reality, but it won't happen through passionate essays on "free as in freedom" or the proper way to pronounce "GNU" or the benefits of using Gentoo instead of Arch. It'll only come if someone can unify all the splintered groups around a cohesive, simple message and market it to the public.' -- source: https://linux.slashdot.org/story/19/11/03/2012226 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/

Incognito Mode For Google Maps Arrives On Android
by Peter Reutemann 01 Nov '19

01 Nov '19

'Incognito Mode for Google Maps is rolling out to Android users to prevent your search queries and real-time tracked location from being recorded onto your Google account. Engadget reports: It's not something you'll want to use all the time as some features will be disabled, and it's important to note that it doesn't turn off all tracking. The places you go won't be saved to your Location History (if you have that enabled), your searches won't be saved to your account and it won't use your information to personalize the experience. Still, you could be tracked by internet service providers, other apps, or if you're using Assistant and other Google services. Similar to incognito on Chrome, it's more useful as a depersonalized look at recommendations than as a full-fledged privacy protector, and a way to make sure that whatever you're searching for in this instance doesn't affect your recommendations later -- don't worry, we're not judging.

Google's Network Congestion Algorithm Isn't Fair, Researchers Say
by Peter Reutemann 01 Nov '19

01 Nov '19

'Researchers at Carnegie Mellon University say a Google algorithm designed help reduce internet congestion is mathematically unfair, resulting in network management systems that may disadvantage some traffic over others. From a report: Several years back, Google began work on a new open source congestion control algorithm (CCA) designed to improve the way the internet functions. The result was BBR, short for Bottleneck Bandwidth and RTT (Round-Trip Time). The goal of the project: to improve how network packets travel between servers to mitigate congestion on the internet. CCAs have long been used to help manage congestion -- ideally while treating all traffic equally. But in a study unveiled last week at the Internet Measurement Conference in Amsterdam, researchers revealed that BBR doesn't actually do a very good job of that last part. In fact, they found that during periods of congestion, BBR connections would take up 40 percent of the available bandwidth, leaving the remaining 60 percent to be fought over by the remaining users on the network.' -- source: https://tech.slashdot.org/story/19/10/31/204226 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/

Text Editor Releases 'Free Uyghur' Edition, Gets Swamped With Chinese Spam
by Peter Reutemann 01 Nov '19

01 Nov '19

Something from the Windows open-source camp rather than Linux: 'This week, the developer of the popular text- and code-editing software Notepad++ released a new version update. Nothing seemed particularly strange about it, except maybe the name: Notepad++ v7.8.1 is the "Free Uyghur" edition. In a blog post announcing the updated version, developer Don Ho writes about the plight of the Uyghur people, an ethnic minority in China that's faced persecution from the country's authoritarian government. China operates internment camps that are used to detain Uyghur people throughout the country's Xinjiang region. Since the announcement, the software's GitHub "issues" page has been bombarded with spam, much of it in the Chinese language. "Stop sending meaningless political-related issues, it just makes you look like an idiot," reads one comment. Another one simply reads, "Bye ! Uninstall." There's a litany of curses, and one asks, "What do you know about China?" Others have moved in to criticize the Chinese government in response. Ho told The Verge that the software's dedicated site was also under a distributed-denial-of-service attack, but that it has been stopped by an anti-DDoS service provided by the site's host. Ho writes in the announcement that he anticipated potential pushback, saying "talking about politics is exactly what software and commercial companies generally try to avoid," but decided to take the step anyway. "The problem is," Ho writes in the announcement of the Free Uyghur edition, "if we don't deal with politics, politics will deal with us.' -- source: https://tech.slashdot.org/story/19/10/31/0037247 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 'Unremovable' XHelper Malware Has Infected 45,000 Android Devices
by Peter Reutemann 30 Oct '19

30 Oct '19

'Over the past six months, a new Android malware strain has made a name for itself after popping up on the radar of several antivirus companies, and annoying users thanks to a self-reinstall mechanism that has made it near impossible to remove. Named xHelper, this malware was first spotted back in March but slowly expanded to infect more than 32,000 devices by August (per Malwarebytes), eventually reaching a total of 45,000 infections this month (per Symantec). The malware is on a clear upward trajectory. Symantec says the xHelper crew is making on average 131 new victims per day and around 2,400 new victims per month. Most of these infections have been spotted in India, the U.S., and Russia. According to Malwarebytes, the source of these infections is "web redirects" that send users to web pages hosting Android apps. These sites instruct users on how to side-load unofficial Android apps from outside the Play Store. Code hidden in these apps downloads the xHelper trojan. The good news is that the trojan doesn't carry out destructive operations. According to both Malwarebytes and Symantec, for most of its operational lifespan, the trojan has shown intrusive popup ads and notification spam. The ads and notifications redirect users to the Play Store, where victims are asked to install other apps -- a means through which the xHelper gang is making money from pay-per-install commissions. What's interesting about xHelper is that it gains access to an Android device via an initial app and installs itself as a separate self-standing service. Furthermore, you can't remove the app, as the trojan reinstalls itself every time, even after users perform a factory reset.' -- source: https://tech.slashdot.org/story/19/10/29/2121244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How a months-old AMD microcode bug destroyed my weekend [UPDATED]
by Peter Reutemann 30 Oct '19

30 Oct '19

'This weekend, I was excited to deploy my first Ryzen 3000-powered workstation in my home office. Unfortunately, a microcode bug—originally discovered in July but still floating around in large numbers in the wild—wrecked my good time. I eventually got my Ryzen 3700X system working, and it's definitely fast. But unfortunately, it's still bugged, and there's no easy way to fix it. Not long after the product launch, AMD Ryzen 3000 customers started noticing problems with their shiny new CPUs. Windows users couldn't successfully launch Destiny 2 (due to a power-management bug, unrelated to the one sidelining my system), and Linux users in many cases couldn't even get their system to boot. Jason Evangelho covered the initial discovery and report of the bug at Forbes back in July, and an AMD representative provided him with a statement by email: "AMD has identified the root cause and implemented a BIOS fix for an issue impacting the ability to run certain Linux distributions and Destiny 2 on Ryzen 3000 processors. We have distributed an updated BIOS to our motherboard partners, and we expect consumers to have access to the new BIOS over the coming days." This sounds happy and upbeat, but the reality isn't quite so simple. When there's a bug in the CPU microcode, you're at the mercy of your motherboard vendor to release a new system BIOS that will update it for you—you can't just go to some download link at AMD and apply a fix yourself. AMD responded to the bug in July. As far as I can tell, AMD did so only by direct email response; there's no press release about it—and the company's response made it sound like everything would be fixed in a week or two. I have the unfortunate duty of reporting to you, three months later, that it is not.' -- source: https://arstechnica.com/gadgets/2019/10/how-a-months-old-amd-microcode-bug-… 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/

50 Years Ago, the Internet Was Born In Room 3420

'The BBC has made its international news website available via the Tor network, in a bid to thwart censorship attempts.

Chrome 78 Arrives With New APIs, Dark Mode Improvements On Android and iOS
by Peter Reutemann 23 Oct '19

23 Oct '19

'Google today launched Chrome 78 for Windows, Mac, Linux, Android, and iOS. The release includes the CSS Properties and Values API, Native File System API, new Origin Trials, and dark mode improvements on Android and iOS. You can update to the latest version now using Chrome's built-in updater or download it directly from google.com/chrome. With over 1 billion users, Chrome is both a browser and a major platform that web developers must consider. In fact, with Chrome's regular additions and changes, developers often have to stay on top of everything available -- as well as what has been deprecated or removed. Chrome 78, for example, removes the XSS Auditor due to privacy concerns. Chrome 78 implements the CSS Properties and Values API to let developers register variables as full custom properties. There's a new Native File System API that lets developers build web apps that interact with files on the user's local device. Chrome 78 adds to the Original Trials introduced in Chrome 77, such as Signed Exchanges and SMS Receiver API. "The former allow a distributor to provide content signed by a publisher," reports VentureBeat. "The latter allows websites to access SMS messages that are delivered to the user's phone." Other features that are rolling out gradually include the ability to be able to highlight and right-click a phone number link in Chrome and forward the call to their Android device. "Some users might also see an option to share their clipboard content between their computers and Android devices," adds VentureBeat. "Chrome is also getting Google Drive integration. From Chrome's address bar, you will be able to search for Google Drive files that you have access to."

An Interview With Former Purism CTO Zlatan Todoric Hints At Chaos At Purism
by Peter Reutemann 23 Oct '19

'Phoronix published an interview with former Purism CTO Zlatan Todoric who left Purism in September 2018. The story hints quite strongly at chaotic situations over at Purism. He started at the company in 2015, when it was a small outfit, and steered it into the bigger company that it is now. To him the smartphone development for the Librem 5 was a mistake and way too early. He has high hopes for the Pinephone, who according to him are doing things right.

Disney+ Does Not Work On Linux Devices
by Peter Reutemann 22 Oct '19

22 Oct '19

'If you plan on streaming content from the new Disney+ streaming service on Linux devices, you'll likely be greeted with Error Code 83. Fedora Linux package maintainer Hans De Goede from the Netherlands first made the unpleasant discovery. gHacks reports: De Goede noticed that Disney+ would not work in any of the web browsers that he tried on systems running Fedora Linux. He tried Firefox and Chrome, and both times Disney+ threw the error "error code 83." Disney+ Support was not able to assist de Goede. It replied with a generic message stating that the error was known and that it happened often when customers tried to play Disney+ in web browsers or using certain devices. Support recommended to use the official applications on phones or tablets to watch the shows or movies. Other streaming services, e.g. Netflix, work fine on Linux. A user on the Dutch site Tweakers dug deeper and uncovered the response code that the site returned when a device or browser was used that could not be used to play streams. According to the information, error code 83 means that the platform verification status is incompatible with the security level. Disney uses the DRM solution Widevine to protect its streams from unauthorized activity. Widevine supports three different security levels, called 1, 2 and 3, which have certain requirements. The supported level determines the maximum stream quality and may even prevent access to a stream if the requirements are not met. It appears that Disney set Widevine to a more restrictive level than its competitors. The decision affects Disney+ on Linux devices and on other devices that don't support the selected Widevine security standard.

Remember Sure-Fi? Lostik is open standards Lora you can play with
by Peter Reutemann 22 Oct '19

22 Oct '19

'A lot of readers commented on our earlier report on Sure-Fi long-range, low-bandwidth RF chirp communicators that we should test generic Lora gear. Lora is the open standard that Sure-Fi began with and built on top of, and it's available in a variety of inexpensive kits. Most of those kits are aimed at low-level maker-style integration with IoT gear like Arduino, but I found a couple of preassembled kits with generic USB interfaces suitable for use with regular x86 computers. One of those, Lostik, had consistently better user reviews and glowingly boasted of its "extensive documentation," so we picked a pair up for $46 apiece and got to testing. We should be clear about one thing up front—nobody should claim that any Lora device has "extensive documentation" with a straight face. Lostik seems to have more documentation than any of its competitors, but figuring out exactly what it would do felt like learning to play pirated video games in the 1980s. What we eventually discovered was that Lora devices are sort of like dial-up modems all connected to a single party line—they run on serial interfaces over which they can be issued commands and can send or receive data. It's possible to use a generic terminal emulator (at 57,600bps, 8 data bits, 1 stop bit, and no parity) to communicate directly with Lostik, but you'll need to understand its commands—analogous to the Hayes AT modem commands of yore—if you do. That was a bridge too far for us, so we said the heck with it and just lightly modified the ./sender.py and ./receiver.py sample scripts from Lostik's Github repository and used them for some simple range testing. These scripts don't require (or offer) any kind of authentication or pairing; any Lora device running receiver.py will successfully receive data from any Lora device running sender.py within its effective range.' -- source: https://arstechnica.com/gadgets/2019/10/lostik-usb-lora-radios/ 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/

Popular VPN Service NordVPN Says it Was Hacked
by Peter Reutemann 22 Oct '19

22 Oct '19

'NordVPN, a virtual private network provider that promises to "protect your privacy online," has confirmed it was hacked. From a report: The admission comes following rumors that the company had been breached. It first emerged that NordVPN had an expired internal private keys exposed, potentially allowing anyone to spin out their own servers imitating NordVPN. For its part, NordVPN has claimed a "zero logs" policy. "We don't track, collect, or share your private data," the company says. But the breach is likely to cause alarm that hackers may have been in a position to access some user data. NordVPN told TechCrunch that one of its datacenters was accessed in March 2018. "One of the datacenters in Finland we are renting our servers from was accessed with no authorization," said NordVPN spokesperson Laura Tyrell. The attacker gained access to the server -- which had been active for about a month -- by exploiting an insecure remote management system left by the datacenter provider, which NordVPN said it was unaware that such a system existed.' -- source: https://it.slashdot.org/story/19/10/21/1447208 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/

Visiting New Zealand
by Aaron 21 Oct '19

21 Oct '19

I am a longtime Linux developer and will be staying with friends in Rotarua from Feb 2 through April 21. I'd love to both attend and present at a Linux User Group while I'm there. Presentation idea description: The voice interface represents another big shift in user interfaces, and could be as big a shift as the shift from switches to terminals, the switch from terminals to windowed GUIs, or the switch from full computers to small touchscreen devices. Unfortunately, right now most of these devices are little more than a telephone for talking to a server in the cloud. That is a big problem for privacy, and presents the user with a false choice between access and privacy. Today's computers are capable of handling a verbal interface without requiring a cloud service to handle all of your requests. I am one of the developers on the Naomi Project, a free and open source voice assistant (https://projectnaomi.com) It is a plugin based system based on Jasper (http://jasperproject.github.io/) and depending on how the user chooses to configure it, can run totally offline. In this presentation, I'd like to introduce people to the Naomi Project, talk about the benefits of a verbal interface, talk about the current architectures of virtual assistants, and ways in which that architecture can be altered to provide better privacy, and also do a comparison of offline speech to text and text to speech solutions, including Pocketsphinx, Mozilla Deepspeech, Kaldi, and Julius. Finally, I will invite people to participate in building and improving Naomi. There is a lot to do and much of it is both engaging and cutting-edge. Please let me know if you are interested, or if you know of other active groups I should contact. Thanks, Aaron

Researchers abuse Alexa and Google Home to eavesdrop and phish passwords
by Peter Reutemann 21 Oct '19

21 Oct '19

'By now, the privacy threats posed by Amazon Alexa and Google Home are common knowledge. Workers for both companies routinely listen to audio of users—recordings of which can be kept forever—and the sounds the devices capture can be used in criminal trials. Now, there's a new concern: malicious apps developed by third parties and hosted by Amazon or Google. The threat isn't just theoretical. Whitehat hackers at Germany's Security Research Labs developed eight apps—four Alexa "skills" and four Google Home "actions"—that all passed Amazon or Google security-vetting processes. The skills or actions posed as simple apps for checking horoscopes, with the exception of one, which masqueraded as a random-number generator. Behind the scenes, these "smart spies," as the researchers call them, surreptitiously eavesdropped on users and phished for their passwords.' -- source: https://arstechnica.com/information-technology/2019/10/alexa-and-google-hom… 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/

Project Trident Ditches BSD For Linux
by Peter Reutemann 21 Oct '19

21 Oct '19

'Project Trident is moving from FreeBSD to Void Linux, reports Its FOSS: According to a later post, the move was motivated by long-standing issues with FreeBSD. These issues include "hardware compatibility, communications standards, or package availability continue to limit Project Trident users". According to a conversation on Telegram, FreeBSD has just updated its build of the Telegram client and it was nine releases behind everyone else. The lead dev of Project Trident, Ken Moore, is also the main developer of the Lumina Desktop. The Lumina Desktop has been on hold for a while because the Project Trident team had to do so much work just to keep their packages updated. (Once they complete the transition to Void Linux, Ken will start working on Lumina again.) After much searching and testing, the Project Trident team decided to use Void Linux as their new base. More from the Project Trident site: It's important to reiterate that Project Trident is a distribution of an existing operating system. Project Trident has never been a stand-alone operating system. The goal of Project Trident is enhancing the usability of an operating system as a graphical workstation through all sorts of means: custom installers, automatic setup routines, graphical utilities, and more... The more we've tested Void Linux, the more impressed we have been. We look forward to working with an operating system that helps Project Trident continue to provide a stable, high-quality graphical desktop experience.' -- source: https://linux.slashdot.org/story/19/10/20/2227228 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/

Mozilla is Sharing YouTube Horror Stories To Prod Google For More Transparency
by Peter Reutemann 21 Oct '19

21 Oct '19

'CNET reports on a new crowdsourced public awareness campaign: Mozilla is publishing anecdotes of YouTube viewing gone awry -- anonymous stories from people who say they innocently searched for one thing but eventually ended up in a dark rabbit hole of videos. It's a campaign aimed at pressuring Google's massive video site to make itself more accessible to independent researchers trying to study its algorithms. "The big problem is we have no idea what is happening on YouTube," said Guillaume Chaslot, who is a fellow at Mozilla, a nonprofit best known for its unit that makes and operates the Firefox web browser. Chaslot is an ex-Google engineer who has investigated YouTube's recommendations from the outside after he left the company in 2013. (YouTube says he was fired for performance issues.) "We can see that there are problems, but we have no idea if the problem is from people being people or from algorithms," he said.... Mozilla is publishing 28 stories it's terming #YouTubeRegrets; they include, for example, an anecdote from someone who who said a search for German folk songs ended up returning neo-Nazi clips, and a testimonial from a mother who said her 10-year-old daughter searched for tap-dancing videos and ended up watching extreme contortionist clips that affected her body image.

WAV Audio Files Are Now Being Used To Hide Malicious Code

'Two reports published in the last few months show that malware operators are experimenting with using WAV audio files to hide malicious code.

The second malware campaign was spotted this month by BlackBerry Cylance. In a report published today and shared with ZDNet last week, Cylance said it saw something similar to what Symantec saw a few months before. But while the Symantec report described a nation-state cyber-espionage operation, Cylance said they saw the WAV steganography technique being abused in a run-of-the-mill crypto-mining malware operation.' -- source: https://it.slashdot.org/story/19/10/20/200249 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/

Privacy-Respecting Smart Home System Can Work Offline and Sends Fake Data
by Peter Reutemann 21 Oct '19

21 Oct '19

'A publicly-funded group of designers, artists and privacy experts from Amsterdam have designed a smart home system prototype to "prove it's technically possible to build a privacy respecting smart home while maintaining convenience." Its controller uses an Arduino Nano to disconnect the system from the internet during times when it's not in use. They're building everything on Mozilla's open smart home gateway software. The system's microphone is a separate USB device that can be easily unplugged. For extra security, the devices don't even use wifi to communicate. "The Candle devices offer the advantages of a smart home system -- such as voice control, handy automations and useful insights -- without the downsides of sending your data to the cloud and feeling watched in your own home," explains their blurb for Dutch Design Week, where they're launching their prototypes of trust-worthy smart locks, thermostats, and other Internet of Things devices: Most smart devices promises us an easier life, but they increasingly disappoint; they eavesdrop, share our data with countless third parties, and offer attractive targets to hackers. Candle is different. Your data never leaves your home, all devices work fine without an internet connection, and everything is open source and transparent. One of the group's members is long-time Slashdot reader mrwireless, who shares an interesting observation: Smart homes track everything that happens inside them. For developing teenagers, this makes it more difficult to sneak in a date or break the rules in other subtle ways, which is a normal, healthy part of growing up. Candle is a prototype smart home that tries to mitigate these issue. It has given its sensors the ability to generate fake data for a while. In the future, children could get a monthly fake data allowance. Some of the devices have "skirts", simple fabric covers that can be draped over the devices to hide their screen. If you own a dust sensor, this can be useful if your mother in law comes over and you haven't vacuumed in a while.' -- source: https://yro.slashdot.org/story/19/10/20/216238 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/

Unpatched Linux bug may open devices to serious attacks over Wi-Fi
by Peter Reutemann 18 Oct '19

18 Oct '19

'A potentially serious vulnerability in Linux may make it possible for nearby devices to use Wi-Fi signals to crash or fully compromise vulnerable machines, a security researcher said. The flaw is located in the RTLWIFI driver, which is used to support Realtek Wi-Fi chips in Linux devices. The vulnerability triggers a buffer overflow in the Linux kernel when a machine with a Realtek Wi-Fi chip is within radio range of a malicious device. At a minimum, exploits would cause an operating-system crash and could possibly allow a hacker to gain complete control of the computer. The flaw dates back to version 3.10.1 of the Linux kernel released in 2013. "The bug is serious," Nico Waisman, who is a principal security engineer at Github, told Ars. "It's a vulnerability that triggers an overflow remotely through Wi-Fi on the Linux kernel, as long as you're using the Realtek (RTLWIFI) driver." The vulnerability is tracked as CVE-2019-17666. Linux developers proposed a fix on Wednesday that will likely be incorporated into the OS kernel in the coming days or weeks. Only after that will the fix make its way into various Linux distributions.' -- source: https://arstechnica.com/information-technology/2019/10/unpatched-linux-flaw… 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/

IBM+Red Hat: A Successful Acquisition For A Change?
by Lawrence D'Oliveiro 18 Oct '19

18 Oct '19

IBM reports <https://www.theregister.co.uk/2019/10/17/ibm_q3_2019_financials/> that its Red Hat division has been doing quite nicely since it was acquired. This is in contrast to the rest of the company, which seems to be continuing its long, slow downward slide. I have seen mention elsewhere of economic studies that show that, on average, corporate mergers and acquisitions tend to destroy value rather than create it (e.g. the all-too-common scenario of “big company buys small company and then drives away its customers and shuts it down”). The realization of actual “synergies” seems to be the exception rather than the rule. Maybe IBM will continue jettisoning its other parts, and end up being just Red Hat in all but name...

Bug In Python Script May Have Affected Hundreds Of Studies
by Lawrence D'Oliveiro 18 Oct '19

18 Oct '19

A set of Python scripts popularly used to analyze chemistry data has had a long-standing bug in that it had assumptions about the order in which filenames in a directory would be returned <https://arstechnica.com/information-technology/2019/10/chemists-discover-cr…>. The code worked correctly on Windows and an older version of macOS, but discrepancies crept in on Linux and on newer macOS. The fix was to sort the returned names into a consistent order before processing. I just note this Twitter comment from one of the original authors: When I wrote the scripts 6 years ago, the OS was able to handle the sorting. That would never have been true on Linux. There have never been any guarantees about ordering of directory entries on POSIX-compliant systems. Note the docs <https://docs.python.org/3/library/glob.html#glob.glob> clearly say: Whether or not the results are sorted depends on the file system. One of the researchers who found (and fixed) the bug says ... he hopes the paper will get scientists to pay more attention to the computational side of experiments in the future.

The audit was carried out using rules detailed in a guideline for "modern secure browsers" that the BSI published last month, in September 2019. The BSI normally uses this guide to advise government agencies and companies from the private sector on what browsers are safe to use. The article includes a list of all the minimum requirements required for the BSI to consider a browser "secure."

Google Ejects Open-Source WireGuard From Play Store Over Donation Links
by Peter Reutemann 17 Oct '19

'Google appears to be removing apps that have donation links, including open-source apps where donations are one of the main sources of revenue. WireGuard, a free and open-source VPN, has been reportedly dropped over this according to WireGuard lead developer Jason Donenfeld. Phoronix reports: After waiting days for Google to review the latest version of their secure VPN tunnel application, it was approved and then removed and delisted -- including older versions of WireGuard. The reversal comes on the basis of violating their "payments policy." The only bit of possible "payments" within the WireGuard app is a donation link within the program taking the user to the WireGuard website should anyone want to donate to support this promising open-source secure networking tech. An appeal to the situation was also rejected by Google, Donenfeld has confirmed this morning on their mailing list. In trying to make it back into Android's Play Store, Jason has dropped the donation link from the Android app version while it's still awaiting review from Google.

Calibre Replacement Considerations
by Lawrence D'Oliveiro 17 Oct '19

17 Oct '19

This blog post <https://anarc.at/software/desktop/calibre/> popped up in my screensaver display a few minutes ago, and was interesting enough for me to find the original. Calibre is the well-known software package for viewing and managing ebooks and converting between formats. As the blog writer says: It's used by Linux geeks as well as Windows power-users and vastly surpasses any native app shipped by ebook manufacturers. I know almost exactly zero people that have an ebook reader that do *not* use Calibre. However, there seem to be quite a few problems with it, not the least of which is that the principal developer seems to have trouble appreciating security vulnerabilities. Another issue is that it is written in Python 2 (though an in-progress port to Python 3 seems to be mostly “going well”). At one point the developer claimed that wasn’t a big deal, as he could continue to maintain Python 2 himself after it became obsolete upstream, but he seems to have backtracked from that position. One pressing problem is that newer versions of Calibre depend on Python 2 libraries that are no longer available in Debian (and therefore would also disappear from all the usual Debian derivatives, like Ubuntu and Linux Mint). However, the list of useful functions that Calibre performs is remarkably long, so finding substitutes for them all is going to be rather daunting.

In 2019, multiple open source companies changed course—is it the right move?
by Peter Reutemann 17 Oct '19

17 Oct '19

'Free and open source software enables the world as we know it in 2019. From Web servers to kiosks to the big data algorithms mining your Facebook feed, nearly every computer system you interact with runs, at least in part, on free software. And in the larger tech industry, free software has given rise to a galaxy of startups and enabled the largest software acquisition in the history of the world. Free software is a gift, a gift that made the world as we know it possible. And from the start, it seemed like an astounding gift to give. So astounding in fact that it initially made businesses unaccustomed to this kind of generosity uncomfortable. These companies weren't unwilling to use free software, it was simply too radical and by extension too political. It had to be renamed: "open source." Once that happened, open source software took over the world. Recently, though, there's been a disturbance in the open source force. Within the last year, companies like Redis Labs, MongoDB, and Confluent all changed their software licenses, moving away from open source licenses to more restrictive terms that limit what can be done with the software, making it no longer open source software. The problem, argue Redis Labs, MongoDB and others, is a more modern tech trend: hosted software services. Also known as, "the cloud." Also known as Amazon AWS. Amazon, for its part, came out swinging, releasing its own version of the code behind Elastic Search this spring in response to licensing changes at Elastic (the company behind Elastic Search). And besides a new trademark dispute over Amazon's naming convention, Elastic has a very different response from that of MongoDB and Redis—it hasn't said a word in protest.' -- source: https://arstechnica.com/information-technology/2019/10/is-the-software-worl… 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/

Hard drives
by john 17 Oct '19

17 Oct '19

I sent this yesterday with four screenshots not aware that I may incur the wrath of the moderator. Here is a copy of the e-mail minus the pretty pictures. My neighbor just gave me a couple of failed Sea-gate hard drives to test I put them (one at a time) into my Linux mint machine. They showed up in my computer but would not mount.(see attachments) I ran the "Disks" utility which reported exactly the same problem (one incident of over temperature) for both disks However it stated that the disks were OK. One disk has 500GB of movies and TV series The other 375GB Operas and areas. The disks were used by a Mother and Son on two laptops and were cross pollinated between the two. I doubt that forcing a mount would reap a reward in this case. If any one can help with this it would be neat. Cheers John..

Interview With Fedora Project Leader Matthew Miller On 15 Years of Fedora
by Peter Reutemann 17 Oct '19

17 Oct '19

'Fedora -- as a Linux distribution -- will celebrate the 15th anniversary of its first release in November, though its technical lineage is much older, as Fedora Core 1 was created following the discontinuation of Red Hat Linux 9 in favor of Red Hat Enterprise Linux (RHEL). Five years after the start of Fedora.next, the distribution is on the right track -- stability has improved, and work on minimizing hard dependencies in packages and containers, including more audio/video codecs by default, flicker-free boot, and lowering power consumption for notebooks, among other changes, have greatly improved the Fedora experience, while improvements in upstream projects such as GNOME and KDE have likewise improved the desktop experience. In a wide-ranging interview with TechRepublic, Fedora project leader Matthew Miller discussed lessons learned from the past, popular adoption and competing standards for software containers, potential changes coming to Fedora, as well as hot-button topics, including systemd.' -- source: https://linux.slashdot.org/story/19/10/16/1712207 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/

Hi everyone Came across this news item from meetup.com: https://www.meetup.com/lp/paymentchanges Members will soon get charged USD 2 per month for using meetup.com. So far, it was only the organizers that had to cough up money. The idea is to lower costs for organizers and ensure that people RSVPing actually show up. I'll put this as topic for the upcoming AGM. In the meantime, we should start looking for alternatives. E.g.: https://alternativeto.net/software/meetup/ Personally, I like GetTogether (https://gettogether.community/) 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's Auto-Delete Tools Are Practically Worthless For Privacy
by Peter Reutemann 15 Oct '19

15 Oct '19

'By default, Google collects a vast amount of data on users' behavior, including a lifelong record of web searches, locations, and YouTube views. But amid a privacy backlash and ongoing regulatory threats, the company has started to hype its recently released privacy tools, like the ability to automatically delete some of the data it collects about you -- data that helps power its $116 billion ad business. [...] In reality, these auto-delete tools accomplish little for users, even as they generate positive PR for Google. Experts say that by the time three months rolls around, Google has already extracted nearly all the potential value from users' data, and from an advertising standpoint, data becomes practically worthless when it's more than a few months old. "Anything up to one month is extremely valuable," says David Dweck, the head of paid search at digital ad firm WPromote. "Anything beyond one month, we probably weren't going to target you anyway." Dweck says that in the digital ad industry, recent activity is essential. If you start searching on Google for real estate or looking up housing values, for instance, Google might lump you into a "prospective home buyers" category for advertisers. That information becomes instantly valuable to realtors, appraisers, and lenders for ad targeting, and it could remain valuable for a while as other companies, such as painters or appliance brands, try to follow up on your home buying. Still, it's unusual for advertisers to target users based on their activity from months earlier, Dweck says.' -- source: https://yro.slashdot.org/story/19/10/15/1933230 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/

Flaw In Sudo Enables Non-Privileged Users To Run Commands As Root
by Peter Reutemann 15 Oct '19

15 Oct '19

'A vulnerability has been discovered in Sudo -- one of the most important, powerful, and commonly used utilities that comes as a core command installed on almost every UNIX and Linux-based operating system. The vulnerability in question is a sudo security policy bypass issue that could allow a malicious user or a program to execute arbitrary commands as root on a targeted Linux system even when the "sudoers configuration" explicitly disallows the root access. Sudo, stands for "superuser do," is a system command that allows a user to run applications or commands with the privileges of a different user without switching environments -- most often, for running commands as the root user. The vulnerability, tracked as CVE-2019-14287 and discovered by Joe Vennix of Apple Information Security, is more concerning because the sudo utility has been designed to let users use their own login password to execute commands as a different user without requiring their password. What's more interesting is that this flaw can be exploited by an attacker to run commands as root just by specifying the user ID "-1" or "4294967295." That's because the function which converts user id into its username incorrectly treats -1, or its unsigned equivalent 4294967295, as 0, which is always the user ID of root user. The vulnerability affects all Sudo versions prior to the latest released version 1.8.28, which has been released today.' -- source: https://linux.slashdot.org/story/19/10/14/2231235 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/

Apple's Safari Browser Is Sending Some Users' IP Addresses To China's Tencent
by Peter Reutemann 14 Oct '19

14 Oct '19

'"Apple, which often positions itself as a champion of privacy and human rights, is sending some IP addresses from users of its Safari browser on iOS to Chinese conglomerate Tencent -- a company with close ties to the Chinese Communist Party," reports the Reclaim the Net blog: Apple admits that it sends some user IP addresses to Tencent in the "About Safari & Privacy" section of its Safari settings.... The "Fraudulent Website Warning" setting is toggled on by default which means that unless iPhone or iPad users dive two levels deep into their settings and toggle it off, their IP addresses may be logged by Tencent or Google when they use the Safari browser. However, doing this makes browsing sessions less secure and leaves users vulnerable to accessing fraudulent websites... Even if people install a third-party browser on their iOS device, viewing web pages inside apps still opens them in an integrated form of Safari called Safari View Controller instead of the third-party browser. Tapping links inside apps also opens them in Safari rather than a third-party browser. These behaviors that force people back into Safari make it difficult for people to avoid the Safari browser completely when using an iPhone or iPad. Engadget adds that it's "not clear" whether or not Tencent is actually collecting IP addresses from users outside of China. ("You'll see mention of the collection in the U.S. disclaimer, but that doesn't mean it's scooping up info from American web surfers.") But Reclaim the Net points out that the possibility is troubling, in part because Safari is the #1 most popular mobile internet browser in America, with a market share of over 50%.' -- source: https://apple.slashdot.org/story/19/10/14/033225 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/

Bell Labs Plans Big 50th Anniversary Event For Unix
by Peter Reutemann 14 Oct '19

14 Oct '19

'Photographer Peter Adams launched a "Faces of Open Source" portrait project in 2014. This week he posted a special announcement on the web site of Bell Labs: Later this month, Bell Labs will celebrate the 50th anniversary of Unix with a special two day "Unix 50" event at their historic Murray Hill headquarters. This event should be one for the history books with many notable Unix and computer pioneers in attendance...! As I was making those photographs (which will be on display at the event), I gained much insight into Bell Labs and the development of Unix. However, it was some of the more personal stories and anecdotes that brought Bell Labs to life and gave me a feel for the people behind the code. One such time was when Ken Thompson (who is an accomplished pilot) told me how he traveled to Russia after the fall of the Soviet Union in order to fly in a MiG-29 fighter jet... Brian Kernighan told me about how a certain portrait of Peter Weinberger found its way into some very interesting places. These included the concrete foundation of a building on Bell Labs campus, the cover images printed onto Unix CD-ROMs, and most notably, painted on the top of a nearby water tower. Which brings us to another important piece of Unix mythology that I learned about: the fictitious Bell Labs employee G.R. Emlin (a.k.a. "the gremlin").... A lot of this folklore (including the gremlin) is going to be on display at the Unix 50 event. The archivists at Bell Labs have outdone themselves by pulling together a massive collection of artifacts taken from the labs where Unix was developed for over 30 years. I was able to photograph a few of these artifacts last year, but so much more will be exhibited at this event -- including several items from the personal archives of some attendees. As if that wasn't enough, the event will also showcase a number of vintage computers and a look into Bell Labs future with a tour of their Future X Labs. The article includes some more quick stories about the Unix pioneers at Bell Labs (including "the gremlin") and argues that "the decision to freely distribute Unix's source code (to anyone who asked for it) inadvertently set the stage for the free and open source software movements that dominate the technology industry today... "In hindsight, maybe 1969 should be called the 'summer of code.'"' -- source: https://tech.slashdot.org/story/19/10/12/1625237 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/

Planting tiny spy chips in hardware can cost as little as $200
by Peter Reutemann 14 Oct '19

14 Oct '19

'More than a year has passed since Bloomberg Businessweek grabbed the lapels of the cybersecurity world with a bombshell claim: that Supermicro motherboards in servers used by major tech firms, including Apple and Amazon, had been stealthily implanted with a chip the size of a rice grain that allowed Chinese hackers to spy deep into those networks. Apple, Amazon, and Supermicro all vehemently denied the report. The National Security Agency dismissed it as a false alarm. The Defcon hacker conference awarded it two Pwnie Awards, for "most overhyped bug" and "most epic fail." And no follow-up reporting has yet affirmed its central premise. But even as the facts of that story remain unconfirmed, the security community has warned that the possibility of the supply chain attacks it describes is all too real. The NSA, after all, has been doing something like it for years, according to the leaks of whistle-blower Edward Snowden. Now researchers have gone further, showing just how easily and cheaply a tiny, tough-to-detect spy chip could be planted in a company's hardware supply chain. And one of them has demonstrated that it doesn't even require a state-sponsored spy agency to pull it off—just a motivated hardware hacker with the right access and as little as $200 worth of equipment.' -- source: https://arstechnica.com/information-technology/2019/10/planting-tiny-spy-ch… 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/

System76 Will Begin Shipping 2 Linux Laptops With Coreboot-Based Open Source Firmware
by Peter Reutemann 10 Oct '19

'System76, the Denver-based Linux PC manufacturer and developer of Pop OS, has some stellar news for those who prefer their laptops a little more open. Later this month the company will begin shipping two of their laptop models with its Coreboot-powered open source firmware. >From a report: Beginning today, System76 will start taking pre-orders for both the Galago Pro and Darter Pro laptops. The systems will ship out later in October, and include the company's Coreboot-based open source firmware which was previously teased at the 2019 Open Source Firmware Conference. (Coreboot, formerly known as LinuxBIOS, is a software project aimed at replacing proprietary firmware found in most computers with a lightweight firmware designed to perform only the minimum number of tasks necessary to load and run a modern 32-bit or 64-bit operating system.) What's so great about ripping out the proprietary firmware included in machines like this and replacing it with an open alternative? To begin with, it's leaner. System76 claims that users can boot from power off to the desktop 29% faster with its Coreboot-based firmware. [...] Both of these laptops can be kitted out with 10th-Generation Intel CPUs (specifically the i5-10210U and the i7-10510U), and both have glare-resistant matte 1080p IPS displays. Beginning at $949, the Galago Pro features an all-aluminum chassis, a wealth of connectivity options including HDMI, DisplayPort to USB-C and Thunderbolt, and can be configured with up to 32GB of RAM and up to 6TB of storage space. The Darter Pro, meanwhile, can be built out with 32GB of RAM and up to 2TB of storage, and features up to 10 hours of battery life.' -- source: https://hardware.slashdot.org/story/19/10/10/1847228 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/

Forum cracks the vintage passwords of Ken Thompson and other Unix pioneers
by Peter Reutemann 10 Oct '19

10 Oct '19

'As one of the original versions of Unix, BSD is an ancient operating system. So it shouldn’t come as a surprise that it used what are, by today’s standards, strange, even ridiculous security. For one, the hashing function protecting passwords, though state of the art 40 years ago, is now trivial to crack. Stranger still, the password hashes of some BSD creators were included in publicly available source code. And then, there are the passwords people chose. Last week, technologist Leah Neukirchen reported finding a source tree for BSD version 3, circa 1980, and successfully cracking passwords of many of computing’s early pioneers. In most of the cases the success was the result of the users choosing easy-to-guess passwords. BSD co-inventor Dennis Ritchie, for instance, used “dmac” (his middle name was MacAlistair); Stephen R. Bourne, creator of the Bourne shell command line interpreter, chose “bourne”; Eric Schmidt, an early developer of Unix software and now the executive chairman of Google parent company Alphabet, relied on “wendy!!!” (the name of his wife); and Stuart Feldman, author of Unix automation tool make and the first Fortran compiler, used “axolotl” (the name of a Mexican salamander). Weakest of all was the password for Unix contributor Brian W. Kernighan: “/.,/.,”—representing a three-character string repeated twice using adjacent keys on a QWERTY keyboard. (None of the passwords included the quotation marks.) But there were at least five plaintext passwords that remained out of reach. They included those belonging to Turkish computer scientist Özalp Babaoğlu, Unix software developer Howard Katseff, and crucial Unix contributors Tom London and Bob Fabry. But the uncracked hash that seemed to occupy Neukirchen the longest was the password used by Ken Thompson, another Unix co-inventor. “I never managed to crack ken's password with the hash ZghOT0eRm4U9s, and I think I enumerated the whole 8 letter lowercase + special symbols key space,” Neukirchen reported in the above-linked thread, posted to the Unix Heritage Society mailing list. “Any help is welcome.' -- source: https://arstechnica.com/information-technology/2019/10/forum-cracks-the-vin… 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/

Schneier Slams Australia's Encryption Laws and CyberCon Speaker Bans
by Peter Reutemann 09 Oct '19

09 Oct '19

'Governments breaking encryption is bad, and "will get worse once breaking encryption means people can die," says one of the world's leading security experts. From a report: "Australia has some pretty draconian laws about forcing tech companies to break security," says cryptographer and computer security professional Bruce Schneier. He's referring to the controversial Telecommunications and Other Legislation Amendment (Assistance and Access) Act 2018, which came into force in December. "I actually don't like that, because stuff that you do flows downhill to the US. So stop doing that," he told the Australian Cybersecurity Conference, or CyberCon, in Melbourne on Wednesday. Schneier's argument against breaking encrypted communications is simple. "You have to make a choice. Either everyone gets to spy, or no one gets to spy. You can't have 'We get to spy, you don't.' That's not the way the tech works," he said. "As this tech becomes more critical to life, we simply have to believe, accept, that securing it is more important than leaving it insecure so you can eavesdrop on the bad guys."' -- source: https://it.slashdot.org/story/19/10/09/1855255 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/

Tor Project Removes 13.5% of Current Servers For Running EOL Versions
by Peter Reutemann 09 Oct '19

09 Oct '19

'The Tor Project has removed from its network this week more than 800 servers that were running outdated and end-of-life (EOL) versions of the Tor software. The removed servers represent roughly 13.5% of the 6,000+ servers that currently comprise the Tor network and help anonymize traffic for users across the world. Roughly 750 of the removed servers represent Tor middle relays, and 62 are exit relays -- where users exit the Tor network onto the world wide web after having their true location hidden through the Tor network. The organization said it plans to release a Tor software update in November that will natively reject connections with EOL Tor server versions by default, without any intervention from the Tor Project staff. "Until then, we will reject around 800 obsolete relays using their fingerprints," the Tor Project said in a statement this week.' -- source: https://tech.slashdot.org/story/19/10/09/1853238 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/

Critical Remote Code Execution Flaw Fixed In Popular Terminal App For MacOS
by Peter Reutemann 09 Oct '19

09 Oct '19

'iTerm2 users: It's time to upgrade. A security audit sponsored by the Mozilla Open Source Support Program uncovered a critical remote code execution (RCE) vulnerability in the popular open-source terminal app for macOS. ITerm2 is an open-source alternative to the built-in macOS Terminal app, which allows users to interact with the command-line shell. Terminal apps are commonly used by system administrators, developers and IT staff in general, including security teams, for a variety of tasks and day-to-day operations. The iTerm2 app is a popular choice on macOS because it has features and allows customizations that the built-in Terminal doesn't, which is why the Mozilla Open Source Support Program (MOSS) decided to sponsor a code audit for it. The MOSS was created in the wake of the critical and wide-impact Heartbleed vulnerability in OpenSSL with the goal of sponsoring security audits for widely used open-source technologies. The flaw, which is now tracked as CVE-2019-9535, has existed in iTerm2 for the past seven years and is located in the tmux integration. Tmux is a terminal multiplexer that allows running multiple sessions in the same terminal window by splitting the terminal screen. The flaw was fixed in iTerm2 version 3.3.6, which was released today.' -- source: https://apple.slashdot.org/story/19/10/09/2048214 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/

Essential Reveals Project Gem Smartphone With Very Long, Unusual Design
by Peter Reutemann 09 Oct '19

09 Oct '19

'Andy Rubin, the controversial mobile industry executive who co-founded Android, left Google amid allegations of sexual misconduct while retaining a huge severance package, and went on to create the Essential Phone, has tweeted photos teasing an upcoming device with an elongated design and very tall UI composed of card-like apps. The Verge reports: It look extremely small in his hands, too. The device has a large button and volume rocker on the right edge and a fingerprint divot around back, below what appears to be a single main camera. And as you can see, these devices have some decidedly flashy finishes that change color when you view them at different angles -- a sea green that shifts to yellow and blue, for example. An Essential spokesperson confirmed to the The Verge that this is the company's new phone, adding: "We've been working on a new device that's now in early testing with our team outside the lab. We look forward to sharing more in the near future." A couple hours later, Essential tweeted some slightly more official images of the new phone, which it's calling Project Gem. XDA-Developers also spotted some leaked code that mentions the divot on the rear of the device may activate its voice assistant when you tap your finger to it. They also suggest it runs Android and packs a Qualcomm Snapdragon 730 processor.

Intel Kills Kaby Lake G, Vows To Offer Drivers For Five Years
by Peter Reutemann 09 Oct '19

09 Oct '19

'When Kaby Lake G debuted at CES 2018, it made a big bang. No one expected sworn rivals Intel and AMD to collaborate on a CPU package, marrying a 7th-gen Kaby Lake CPU with a unique AMD Radeon RX Vega GPU. But what began with a bang ended Monday with an unceremonious memo. >From a report: The Product Change Notification published by Intel on Monday confirmed that pretty much every single Kaby Lake G, including the Core i7-8706G, the Core i7-8705G, and the Core i5-8305G, would be discontinued. Last call for orders will be on January 17, 2020, and the final shipments are scheduled for July 31, 2020. While the end of life of a processor isn't typically a big deal to consumers who own them, one sticking point could have been driver support. Specifically, Kaby Lake G drivers for the custom AMD Radeon RX Vega M graphics come only from Intel. With a normal discrete GPU, the consumer would download drivers from the original company, such as Nvidia or AMD. With Kaby Lake G kaput, where does that leave Kaby Lake G-owners? Intel said the company will follow its standard policy and provide driver support for Kaby Lake G for five years from the launch of the product. All told, that probably means another 3.5 years of driver updates.' -- source: https://slashdot.org/story/19/10/09/142229 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/

Fedora Drops 32-Bit Linux
by Peter Reutemann 09 Oct '19

09 Oct '19

'Brian Fagioli, writing for BetaNews: Beginning with the upcoming version 31 of the operating system, i686 32-bit processor support is being dropped by the Fedora Project. "The i686 architecture essentially entered community support with the Fedora 27 release. Unfortunately, there are not enough members of the community willing to do the work to maintain the architecture. Don't worry, though -- Fedora is not dropping all 32-bit packages. Many i686 packages are still being built to ensure things like multilib, wine, and Steam will continue to work," says Justin Forbes of Fedora Project. Forbes further explains, "While the repositories are no longer being composed and mirrored out, there is a koji i686 repository which works with mock for building 32-bit packages, and in a pinch to install 32-bit versions which are not part of the x86_64 multilib repository. Of course, maintainers expect this will see limited use. Users who simply need to run a 32-bit application should be able to do so with multilib on a 64-bit system."' -- source: https://tech.slashdot.org/story/19/10/09/154256 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/

Internal Email Shows GitHub Plans To Renew ICE Contract
by Peter Reutemann 09 Oct '19

09 Oct '19

'GitHub CEO Nat Friedman explained why the company plans to renew a contract with U.S. Immigration and Customs Enforcement (ICE), even though he and others at GitHub oppose ICE's policy of separating children from parents at the border, Motherboard reported on Wednesday, citing an internal GitHub email. From a report: The email shows the continuing debate within the tech industry about whether companies should work specifically with ICE, and comes as a host of other companies have dealt with employee protests over corporate involvement with ICE. "In August, the GitHub leadership team learned about a pending renewal of our product by the U.S. Immigration & Customs Enforcement (ICE) agency. Since then, we have been talking with people throughout the company, based on our own personal concerns and those raised by Hubbers," Friedman's email reads, referring to GitHub employees. Evan Greer, deputy director at activism group Fight for the Future tweeted a copy of the email on Tuesday. Motherboard also separately obtained a copy of the email from a source inside GitHub. The product up for renewal is a license of GitHub Enterprise Server, an on-premises deployment of GitHub that customers can run on their own server, according to the email. ICE originally bought a license in April, 2016.' -- source: https://developers.slashdot.org/story/19/10/09/1557245 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/

Twitter transgression proves why its flawed 2FA system is such a privacy trap
by Peter Reutemann 09 Oct '19

'If ever there was a surefire way to sour users against a two-factor authentication system that was already highly flawed, Twitter has found it. On Tuesday, the social media site said that it used phone numbers and email addresses provided for 2FA protection to tailor ads to users. Twitter requires users to provide a valid phone number to be eligible for 2FA protection. A working cell phone number is mandatory even when users' 2FA protection is based solely on security keys or authenticator apps, which don't rely on phone numbers to work. Deleting a phone number from a user's Twitter settings immediately withdraws account from Twitter 2FA, as I confirmed just prior to publishing this post.' -- sources: https://arstechnica.com/information-technology/2019/10/twitter-used-phone-n… 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/

'Collapse OS' Is An Open-Source Operating System For the Post-Apocalypse
by Peter Reutemann 09 Oct '19

09 Oct '19

'Collapse OS is a new open-source operating system built specifically for use during humanity's darkest days. According to its creator, software developer Virgil Dupras, Collapse OS is what the people of the future will need to reconfigure their scavenged iPhones. For now, though, he's hosting the project on GitHub and looking for contributors. Motherboard reports: According to the Collapse OS site, Dupras envisions a world where the global supply chain collapses by 2030. In this possible future -- kind of a medium-apocalypse -- populations won't be able to mass produce electronics anymore, but they'll still be an enormous source of political and social power. Anyone who can scavenge electronics and reprogram them will gain a huge advantage over those who don't. Dupras believes that the biggest problem for tech savvy post-apocalyptic people will be microcontrollers -- tiny computers embedded in circuit boards that control the functions of computer systems. Collapse OS will work with Z80 8-bit microprocessors. Though less common today than 16- and 32-bit components, the 8-bit Z80 can be found in desktop computers, cash registers, musical instruments, graphing calculators, and everything in between. In a Reddit Q&A, Dupras explained that the Z80 was chosen "because it's been in production for so long and because it's been used in so many machines, scavenger have good chances of getting their hands on it." According to the product page, Collapse OS currently can run on a homebrew Z80-based computer called the RC2014, and on Reddit Dupras said it could theoretically run on a Sega Genesis console.' -- source: https://news.slashdot.org/story/19/10/08/2036204 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/

You Can Now Overclock a Raspberry Pi 4 For Some Nice Performance Gains
by Peter Reutemann 08 Oct '19

08 Oct '19

'The Raspberry Pi 4 is one of the cheapest single-board computers around. The new 4th generation is a solid performance lift over its predecessor and good bang for the buck if you're interested in learning Linux, working with embedded computing, or just want to kick back and play some retro games on an emulator. In addition, the latest version of the Raspberry Pi Foundation's Linux distribution, Raspbian Buster, comes with a new firmware revision for the tiny DIY PC that removes its 2GHz clock speed limit and allows voltage adjustments to wring out additional performance, with proper cooling of course. In testing, while there are no guarantees in overclocking, HotHardware was able to realize more than a 40% lift in their Raspberry Pi 4's processor clock speed, and a 50% boost to the GPU with an air-cooled mini case kit. Combined, they're not enough to turn the Pi 4 into your every day PC, but the performance gains are measurable and valuable. All it takes is a quick firmware update and a couple of Linux commands to dial things in.' -- source: https://hardware.slashdot.org/story/19/10/08/0312213 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/

D-Link Home Routers Open To Remote Takeover Will Remain Unpatched

'D-Link won't patch a critical unauthenticated command-injection vulnerability in its routers that could allow an attacker to remotely take over the devices and execute code. Threatpost reports: The vulnerability (CVE-2019-16920) exists in the latest firmware for the DIR-655, DIR-866L, DIR-652 and DHP-1565 products, which are Wi-Fi routers for the home market. D-Link last week told Fortinet's FortiGuard Labs, which first discovered the issue in September, that all four of them are end-of-life and no longer sold or supported by the vendor (however, the models are still available as new via third-party sellers). The root cause of the vulnerability, according to Fortinet, is a lack of a sanity check for arbitrary commands that are executed by the native command-execution function. Fortinet describes this as a "typical security pitfall suffered by many firmware manufacturers." With no patch available, affected users should upgrade their devices as soon as possible.

Attackers exploit 0-day vulnerability that gives full control of Android phones
by Peter Reutemann 06 Oct '19

06 Oct '19

'Attackers are exploiting a zero-day vulnerability in Google’s Android mobile operating system that can give them full control of at least 18 different phone models, including four different Pixel models, a member of Google’s Project Zero research group said on Thursday night. There’s evidence the vulnerability is being actively exploited, either by exploit developer NSO Group or one of its customers, Project Zero member Maddie Stone said in a post. NSO representatives, meanwhile, said the "exploit has nothing to do with NSO." Exploits require little or no customization to fully root vulnerable phones. The vulnerability can be exploited two ways: (1) when a target installs an untrusted app or (2) for online attacks, by combining the exploit with a second exploit targeting a vulnerability in code the Chrome browser uses to render content. “The bug is a local privilege escalation vulnerability that allows for a full compromise of a vulnerable device,” Stone wrote. “If the exploit is delivered via the Web, it only needs to be paired with a renderer exploit, as this vulnerability is accessible through the sandbox.”' -- source: https://arstechnica.com/information-technology/2019/10/attackers-exploit-0d… 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/

Russian Malware 'Patches' Chrome and Firefox To Fingerprint TLS Traffic
by Peter Reutemann 06 Oct '19

06 Oct '19

'A Russian cyber-espionage hacker group has been spotted using a novel technique that involves patching locally installed browsers like Chrome and Firefox in order to modify the browsers' internal components. The end goal of these modifications is to alter the way the two browsers set up HTTPS connections, and add a per-victim fingerprint for the TLS-encrypted web traffic that originates from the infected computers... According to a Kaspersky report published this week, hackers are infecting victims with a remote access trojan named Reductor, through which they are modifying the two browsers. This process involves two steps. They first install their own digital certificates to each infected host. This would allow hackers to intercept any TLS traffic originating from the host. Second, they modify the Chrome and Firefox installation to patch their pseudo-random number generation (PRNG) functions. These functions are used when generating random numbers needed for the process of negotiating and establishing new TLS handshakes for HTTPS connections. Turla hackers are using these tainted PRNG functions to add a small fingerprint at the start of every new TLS connection. The attack is being attributed to Turla, "a well-known hacker group believed to operate under the protection of the Russian government," ZDNet reports. And though the remote-access trojan already grants full control over a victim's device, one theory is the modified browsers offer "a secondary surveillance mechanism" if that trojan was discovered and removed. Researchers believe the malware is installed during file transfers over HTTP connections, suggesting an ISP had been compromised, according to the article. "A January 2018 report from fellow cyber-security firm ESET revealed that Turla had compromised at least four ISPs before, in Eastern Europe and the former Soviet space, also with the purpose of tainting downloads and adding malware to legitimate fil' -- source: https://news.slashdot.org/story/19/10/06/2242221 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Might Bring Its Edge Browser To Linux

To Fight Spectre-Like Attacks, Intel Suggests a New Kind of Memory
by Peter Reutemann 06 Oct '19

06 Oct '19

'Intel researchers published a paper last week suggesting a new kind of CPU memory to block side-channel attacks like Meltdown and Spectre, according to ZDNet: SAPM -- or Speculative-Access Protected Memory -- is the work of Intel STORM (STrategic Offensive Research & Mitigations), a team of elite security researchers that Intel assembled since 2017 to work on creating mitigations for all the speculative-execution attacks that have impacted the CPU maker's products. SAPM is only an idea for the moment, and there are no silicon prototypes. Intel STORM engineers only released "the theory and possible implementation options," to provide "a ground base for other researchers to improve upon and also for the industry to consider...." Intel STORM researchers say SAPM will implement protections at the hardware level and will work with both physical and virtual memory addresses. "SAPM can be applied to specific memory ranges, with the attribute that any memory access to such memory type will be instruction-level serialized, meaning that any speculative execution beyond the SAPM-accessing instruction will be stopped pending the successful retirement of this SAPM-accessing instruction," Intel STORM developers said in their short description of SAPM's basic principles... Intel STORM researchers say the second part (backend) of most speculative execution attacks performs the same actions. SAPM was designed to introduce hardware-based protections against the backend part of most attacks. It's because of this concept that Intel's research team believes that SAPM will also future-proof the next generations of Intel CPUs against other -- currently undiscovered -- speculative execution attacks. "Intel STORM researchers don't deny that there's a performance hit," the article adds. "However, this impact is low and could be mitigated further by dropping other existing protections."' -- source: https://hardware.slashdot.org/story/19/10/05/0315201 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/

COSMO and Psions
by tom butz 06 Oct '19

06 Oct '19

The Psions were good as long as there was still a dial-up Internet around: they could even generate the DTMF-tones out of telephone-numbers and use them to dial using your phone's microphone. I've kept a 3c-model because of its database program. None of the Psions actually were phones. As they only supported dial-up Internet, I had a look for ISP's that still supported that, and found one (serving the Australian Outback). Unfortunately they didn't accept new customers. As far as second screens are concerned, a while ago there was a Finnish/Russian phone/PDA that had a black and white additional screen on its back. That one drew very little power and could be used for notes and - checking who called. Typing, however, was as clumsy as on any phone. The COSMO features a colour-screen on its back - coloured LEDs instead obviously would've been as user-friendly as Morse-code (for telling you who was calling, if you didn't want to open your phone). In a perfect world, developers would have come up with a Psion keyboard, Internet/WiFi/Bluetooth capability and a black and white screen at the back. Today's cameras are good at taking/watching photos/videos, and they are a lot less chunky.

The Cosmo Communicator should be shipping to its backers next week <https://www.theregister.co.uk/2019/10/04/planet_launches_cosmo_communicator…>. It has more than a passing resemblance to the Psion clamshell pocket PCs of the 1990s, except this one has an open design, intended to allow it to run a choice of open-source operating systems. This looks to be a niche market, compared to the millions of units shipped by all the usual big-name vendors. But if they can make enough money--and keep enough customers happy--to stay in business, why not?

Attorney General Bill Barr Will Ask Zuckerberg To Halt Plans For End-To-End Encryption Across Facebook's Apps
by Peter Reutemann 03 Oct '19

03 Oct '19

'Attorney General Bill Barr, along with officials from the United Kingdom and Australia, is set to publish an open letter to Facebook CEO Mark Zuckerberg asking the company to delay plans for end-to-end encryption across its messaging services until it can guarantee the added privacy does not reduce public safety. From a report: A draft of the letter, dated Oct. 4, is set to be released alongside the announcement of a new data-sharing agreement between law enforcement in the US and the UK; it was obtained by BuzzFeed News ahead of its publication. Signed by Barr, UK Home Secretary Priti Patel, acting US Homeland Security Secretary Kevin McAleenan, and Australian Minister for Home Affairs Peter Dutton, the letter raises concerns that Facebook's plan to build end-to-end encryption into its messaging apps will prevent law enforcement agencies from finding illegal activity conducted through Facebook, including child sexual exploitation, terrorism, and election meddling. "Security enhancements to the virtual world should not make us more vulnerable in the physical world," the letter reads. "Companies should not deliberately design their systems to preclude any form of access to content, even for preventing or investigating the most serious crimes." The letter calls on Facebook to prioritize public safety in designing its encryption by enabling law enforcement to gain access to illegal content in a manageable format and by consulting with governments ahead of time to ensure the changes will allow this access. While the letter acknowledges that Facebook, which owns Facebook Messenger, WhatsApp, and Instagram, captures 99% of child exploitation and terrorism-related content through its own systems, it also notes that "mere numbers cannot capture the significance of the harm to children."' -- source: https://it.slashdot.org/story/19/10/03/1847213 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/

AMD Ryzen Pro 3000 series desktop CPUs will offer full RAM encryption
by Peter Reutemann 02 Oct '19

02 Oct '19

'Monday, AMD announced Ryzen Pro 3000 desktop CPUs would be available in Q4 2019. This of course raises the question, "What's a Ryzen Pro?" The business answer: Ryzen Pro 3000 is a line of CPUs specifically intended to power business-class desktop machines. The Pro line ranges from the humble dual-core Athlon Pro 300GE all the way through to Ryzen 9 Pro 3900, a 12-core/24-thread monster. The new parts will not be available for end-user retail purchase and are only available to OEMs seeking to build systems around them. >From a more technical perspective, the answer is that the Ryzen Pro line includes AMD Memory Guard, a transparent system memory encryption feature that appears to be equivalent to the AMD SME (Secure Memory Encryption) in Epyc server CPUs. Although AMD's own press materials don't directly relate the two technologies, their description of Memory Guard—"a transparent memory encryption (OS and application independent DRAM encryption) providing a cryptographic AES encryption of system memory"—matches Epyc's SME exactly. AMD Memory Guard is not, unfortunately, available in standard Ryzen 3000 desktop CPUs. If you want to build your own Ryzen PC with full memory encryption from scratch, you're out of luck for now.' -- source: https://arstechnica.com/gadgets/2019/10/amd-ryzen-pro-3000-series-desktop-c… 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/

Most mobile browsers display the Web, that’s it—Vivaldi Mobile can change that
by Peter Reutemann 01 Oct '19

01 Oct '19

'Vivaldi—makers of the power user's favorite Web browser—has finally released a mobile version. Vivaldi for Android (sorry iOS users, it's Android-only for now) brings most of what's great about Vivaldi to your phone, and thanks to Vivaldi's sync service, you can even have all your desktop data on your mobile device. Web browsers are perhaps the most important piece of software we use in 2019. Our devices are often little more than small windows onto the Web, and the browser is what we use to see and explore what's in that window. For all its importance though, the modern browser, especially the mobile Web browser, offers precious little in the way of features. It displays the Web and... that's about it. Want to interact with what you see? You're mostly out of luck. Most people probably like their browser this way. Google, maker of the most widely used mobile browser, rarely does anything without extensive user testing. If Chrome is minimalist, it's safe to assume it's that way because Google has determined that's what its users want. And since most other browsers copy whatever Google Chrome does, most mobile Web browsers end up as minimalistic pieces of software. On the desktop, of course, there has long been an exception to the uniformly dumbed-down offerings of Chrome, Firefox, and Safari—Vivaldi. Led by CEO Jon S. von Tetzchner, co-founder and former CEO of Opera, Vivaldi's primary goal is to build a useful browser, a tool you can bend to your will rather than the other way around. You can customize Vivaldi the way you like. Its preferences may be overwhelming at first glance, but if you dig in, you can make Vivaldi do just about whatever you want it to do. For this reason, Vivaldi is often called a "power user's browser" (as opposed to, I guess, the powerless user's browser). For all that, there was always one big problem with Vivaldi: it was desktop only. The company said it was working on a mobile version from the beginning, and von Tetzchner told me several times he was already using it. But there was nothing for the rest of us. Now Vivaldi Mobile is here (again, for Android users at least). Technically, it's a beta release and all the common cautions regarding beta software apply, but I've been using it for over a month now and have had no problems. Or, I should say, I have had problems, but updates prior to the public release eliminated all of them. And even if there were still bugs, Vivaldi would still be more useful than any other browser on my phone based on this recent testing—and yes, I've tried nearly all of today's mobile browsers, even the small, cottage efforts.' -- source: https://arstechnica.com/information-technology/2019/10/vivaldi-mobile-revie… 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's DNS-Over-TLS Plans Scrutinized By US Congress
by Peter Reutemann 01 Oct '19

01 Oct '19

'Google's plans to implement DNS over TLS in Chrome are being investigated by a committee in the U.S. House of Representatives, while the Justice Department has "recently received complaints" about the practice, according to the Wall Street Journal. An anonymous reader quotes Engadget: While Google says it's pushing for adoption of the technology to prevent spying and spoofing, House investigators are worried this would give the internet giant an unfair advantage by denying access to users' data. The House sent a letter on September 13th asking if Google would use data handled through the process for commercial purposes... Internet service providers are worried that they may be shut out of the data and won't know as much about their customers' traffic patterns. This could "foreclose competition in advertising and other industries," an alliance of ISPs told Congress in a September 19th letter... Mozilla also wants to use the format to secure DNS in Firefox, and the company's Marshall Erwin told the WSJ that the antitrust gripes are "fundamentally misleading." ISPs are trying to undermine the standard simply because they want continued access to users' data, Erwin said. Unencrypted DNS helps them target ads by tracking your web habits, and it's harder to thwart DNS tracking than cookies and other typical approaches.

Linus Torvalds Approves New Kernel 'Lockdown' Feature
by Peter Reutemann 30 Sep '19

30 Sep '19

'"After years of countless reviews, discussions, and code rewrites, Linus Torvalds approved on Saturday a new security feature for the Linux kernel, named 'lockdown'," reports ZDNet: The new feature will ship as a LSM (Linux Security Module) in the soon-to-be-released Linux kernel 5.4 branch, where it will be turned off by default; usage being optional due to the risk of breaking existing systems. The new feature's primary function will be to strengthen the divide between userland processes and kernel code by preventing even the root account from interacting with kernel code -- something that it's been able to do, by design, until now. When enabled, the new "lockdown" feature will restrict some kernel functionality, even for the root user, making it harder for compromised root accounts to compromise the rest of the OS... "When enabled, various pieces of kernel functionality are restricted," said Linus Torvalds, Linux kernel creator, and the one who put the final stamp of approval on the module yesterday. This includes restricting access to kernel features that may allow arbitrary code execution via code supplied by userland processes; blocking processes from writing or reading /dev/mem and /dev/kmem memory; block access to opening /dev/port to prevent raw port access; enforcing kernel module signatures; and many more others, detailed here.' -- source: https://linux.slashdot.org/story/19/09/30/0312211 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 Promises UK Government DNS-Over-HTTPS Won't Be Default in UK
by Peter Reutemann 30 Sep '19

30 Sep '19

'"Despite looking to make DNS-over-HTTPS the default for its American users, Mozilla has assured culture secretary Nicky Morgan that this won't be the case in the UK," reports Gizmodo: DNS-over-HTTPS has been fairly controversial, with the Internet Services Providers Association nominating Mozilla for an 'Internet Villain' over the whole thing, saying it will "bypass UK filtering obligations and parental controls, undermining internet safety standards in the UK." In his letter to Morgan, Mozilla vice president of global policy, trust and security, Alan Davidson, stressed that the company "has no plans to turn on our DNS-over-HTTPS feature by default in the United Kingdom and will not do so without further engagement with public and private stakeholders". He did add that Mozilla does "strongly believe that DNS-over-HTTPS would offer real security benefits to UK citizens. The DNS is one of the oldest parts of the internet's architecture, and remains largely untouched by efforts to make the web more secure. "Because current DNS requests are unencrypted, the road that connects your citizens to their online destination is still open and used by bad actors looking to violate user privacy, attack communications, and spy on browsing activity. People's most personal information, such as their health-related data, can be tracked, collected, leaked and used against people's best interest. Your citizens deserve to be protected from that threat."' -- source: https://news.slashdot.org/story/19/09/29/0434233 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/

Do We Need To Rethink What Free Software Is?
by Peter Reutemann 30 Sep '19

30 Sep '19

'Matthew Garrett is a security developer at Google and a Linux contributor who in 2014 won the Free Software Foundation's annual "Advancement of Free Software" award. But now he's asking if we need to re-think what free software is: If users can pay Amazon to provide a hosted version of a piece of software, there's little incentive for them to pay the authors of that software. This has led to various projects adopting license terms such as the Commons Clause that effectively make it nonviable to provide such a service, forcing providers to pay for a commercial use license instead. In general the entities pushing for these licenses are VC backed companies who are themselves benefiting from free software written by volunteers that they give nothing back to, so I have very little sympathy. But it does raise a larger issue -- how do we ensure that production of free software isn't just a mechanism for the transformation of unpaid labour into corporate profit...? At the same time, people are spending more time considering some of the other ethical outcomes of free software. Copyleft ensures that you can share your code with your neighbour without your neighbour being able to deny the same freedom to others, but it does nothing to prevent your neighbour using your code to deny other fundamental, non-software, freedoms. As governments make more and more use of technology to perform acts of mass surveillance, detention, and even genocide, software authors may feel legitimately appalled at the idea that they are helping enable this by allowing their software to be used for any purpose. The JSON license includes a requirement that "The Software shall be used for Good, not Evil", but the lack of any meaningful clarity around what "Good" and "Evil" actually mean makes it hard to determine whether it achieved its aims. As stewards of the free software definition, the Free Software Foundation should be taking the lead in ensuring that these issues are discussed. The priority of the board right now should be to restructure itself to ensure that it can legitimately claim to represent the community and play the leadership role it's been failing to in recent years, otherwise the opportunity will be lost and much of the activist energy that underpins free software will be spent elsewhere. If free software is going to maintain relevance, it needs to continue to explain how it interacts with contemporary social issues. If any organisation is going to claim to lead the community, it needs to be doing that.' -- source: https://news.slashdot.org/story/19/09/28/1741229 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/

Purism's Librem 5 Phone Starts Shipping. It Can Run Linux Desktop Apps
by Peter Reutemann 30 Sep '19

30 Sep '19

'On Tuesday Purism announced their first Librem 5 smartphones were rolling off the assembly line and heading to customers. "Seeing the amazing effort of the Purism team, and holding the first fully functioning Librem 5, has been the most inspirational moment of Purism's five year history," said their founder and CEO Todd Weaver. On Wednesday they posted a video announcing that the phones were now shipping, and Friday they posted a short walk-through video. "The crowdsourced $700 Linux phone is actually becoming a real product," reports Ars Technica: Purism's demand that everything be open means most of the major component manufacturers were out of the question. Perhaps because of the limited hardware options, the internal construction of the Librem 5 is absolutely wild. While smartphones today are mostly a single mainboard with every component integrated into it, the Librem 5 actually has a pair of M.2 slots that house full-size, off-the-shelf LTE and Wi-Fi cards for connectivity, just like what you would find in an old laptop. The M.2 sockets look massive on top of the tiny phone motherboard, but you could probably replace or upgrade the cards if you wanted... [Y]ou're not going to get cutting-edge hardware at a great price with the Librem 5. That's not the point, though. The point is that you are buying a Linux phone, with privacy and open source at the forefront of the design. There are hardware kill switches for the camera, microphone, WiFi/Bluetooth, and baseband on the side of the phone, ensuring none of the I/O turns on unless you want it to. The OS is the Free Software Foundation-endorsed PureOS, a Linux distribution that, in this case, has been reworked with a mobile UI. Purism says it will provide updates for the "lifetime" of the device, which would be a stark contrast to the two years of updates you get with an Android phone. PureOS is a Debian-based Linux distro, and on the Librem 5, you'll get to switch between mobile versions of the Gnome and KDE environments. If you're at all interested in PureOS, Purism's YouTube page is worth picking through. Dozens of short videos show that, yes, this phone really runs full desktop-class Linux. Those same videos show the dev kit running things like the APT package manager through a terminal, a desktop version of Solitaire, Emacs, the Gnome disk utility, DOSBox, Apache Web Server, and more. If it runs on your desktop Linux computer, it will probably run on the Librem 5, albeit with a possibly not-touch-friendly UI. The Librem 5 can even be hooked up to a monitor, keyboard, and mouse, and you can run all these Linux apps with the normal input tools... Selling a smartphone is a cutthroat business, and we've seen dozens of companies try and fail over the years. Purism didn't just survive long enough to ship a product -- it survived in what is probably the hardest way possible, by building a non-Android phone with demands that all the hardware components use open code. Making it this far is an amazing accomplishment.

Libre-RISC-V 3D CPU/GPU Seeks Grants For Ambitious Expansion
by Peter Reutemann 30 Sep '19

30 Sep '19

'The NLNet Foundation is a non-profit supporting privacy, security, and the "open internet". Now the open source Libre RISC-V hybrid CPU/GPU is applying for eight additional grants from the NLNet Foundation, according to this update from the project's Luke Kenneth Casson Leighton (Slashdot reader #517,947): Details on each Grant Application are on the newly-opened RISC-V Community Forum. The general idea is to kick RISC-V into a commercially-viable mass-volume high gear by putting forward funding proposals for NEON/SSE-style Video Acceleration to be upstreamed for use by ffmpeg, vlc, mplayer and gstreamer; hardware-assisted Mesa 3D (a port of the RADV Vulkan Driver to RISC-V), and a hardware-accelerated OpenCL port to RISC-V. This all in a "Hybrid" fashion (a la NEON/SSE) as opposed to the "usual" way that 3D and Video is done, which hugely complicate both software drivers and applications debugging. In addition, the Libre RISC-V SoC itself is applying for grants to do a gcc port supporting its Vectorisation Engine including auto-vectorisation, and, crucially, to do an entirely Libre-licensed ASIC Layout using LIP6.fr coriolis2, working in tandem with Chips4Makers to create a 180nm commercially-viable single-core dual-issue test ASIC. The process takes approximately 2-3 months for approval. Once accepted, anyone may be the direct (tax-deductible) recipient of NLNet donations, for sub-tasks completed. Worth noting: Puri.sm is sponsoring the project, and, given NLNet's Charitable Status, donations from Corporations (or individuals) are 100% tax-deductible.' -- source: https://hardware.slashdot.org/story/19/09/29/1845252 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/

Richard Stallman Is Still Head of the GNU Project
by Peter Reutemann 30 Sep '19

30 Sep '19

'On Thursday, Richard Stallman reminded the GNU Project mailing list that "On September 16 I resigned as president of the Free Software Foundation, but the GNU Project and the FSF are not the same. I am still the head of the GNU Project (the Chief GNUisance), and I intend to continue as such." The next day, with no explanation, a one-sentence update appeared on his personal blog at Stallman.org announcing that "I hereby step down as head of the GNU Project, effective immediately." But a few commenters on social media speculated that the post could have come from someone who'd hijacked Stallman's site -- and sure enough, that sentence had been removed by Sunday morning. In addition, for what it's worth Techrights.org posted an unconfirmed claim Sunday from "a generally reliable source" that "Stallman.org was defaced by an FSF employee. The deface has been reverted, and the domain appears to now be operating on non-FSF infrastructure..." But whatever's happening, Richard Stallman is still living the life of Richard Stallman. Friday he also posted that he's looking for a room in a shared house or apartment for at least two months. "There should not be a cat (unless hypoallergenic), or a dog that jumps up excitedly on people (unless quite small), or a digital listening device such as Echo, Siri or 'Hello Google', or a card lock that records who opens the door. I will ask about cameras."' -- source: https://news.slashdot.org/story/19/09/29/054211 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/

Roll On The Paperless Office?
by Lawrence D'Oliveiro 30 Sep '19

30 Sep '19

The “Paperless Office” was a prediction from back in the 1970s or so that, with the increasing use of electronic automation for business data processing, the need for paper documents would diminish over time and eventually go away. Then with the increasing popularity of PCs came the demand for printers to print the documents created with them, and it seemed the trend was the opposite--electronic automation was producing even more paper documents than ever, rather than less. Well, maybe we have seen “peak paper”, according to <https://www.theregister.co.uk/2019/09/13/wall_street_analyst_slashes_hp_inc…>: The company is currently trying to dig itself out a hole of its own making: it mis-forecast toner cartridge revenues in EMEA for FY'19 that started in October last year, not factoring in the burgeoning demand for cloned or remanufactured alternatives or - seemingly - that businesses are printing less than they used to.

4K / Ultra High Definition Monitors
by Ian Stewart 27 Sep '19

27 Sep '19

Hi Folks, For those of you at last nights meeting you'll recollect there was some discussion on Ultra High Definition<https://en.wikipedia.org/wiki/4K_resolution> computer monitors (i.e. "4K" monitors). With such a large resolution monitor there were jokes made about sitting on the other side of the room in order to use your computer. Today I found links to a Canadian web-site that seems to have created a science out of how far to sit in front of a TV monitor... https://www.rtings.com/tv/reviews/by-size/size-to-distance-relationship ...and... https://www.rtings.com/tv/learn/4k-ultra-hd-uhd-vs-1080p-full-hd-tvs-and-up… ...apparently you sit closer to a 4K/UHD TV monitor than a 1080/HD TV monitor. In fact, if you sit too far away from a 4K/UHD monitor then there is no point in having one and you should have stuck with a 1080/HD monitor! I notice that PB-Tech for the category of 4K Monitors<https://www.pbtech.co.nz/category/peripherals/monitors/4k-monitors>, the sizes are mostly in the range 24 inch to 32 inch, while 4K TVs<https://www.pbtech.co.nz/category/tv-av/tvs/4k-televisions> have screens in the range 43 inch to 86 inch. The cheapest 32 inch 4K monitor I found was a Kogan 32" Ultra HD 4K FreeSync IPS Monitor (3840 x 2160) that is available by purchasing on-line at NZ$370 plus shipping from kogan<https://www.kogan.com/nz/buy/kogan-32-ultra-hd-4k-freesync-ips-monitor-3840…>. Getting a 4K monitor is one thing, being able to feed it with true 4K created video is the next challenge. I don't think it will be coming out of a Freeview box in NZ for a while ;-) However, with the adoption and take-up of the AV1<https://en.wikipedia.org/wiki/AV1> standard, then more 4K video content should become available to stream from the internet. If your Desktop PC doesn't have a 4K (3980 x 1920 pixel) graphics capability, then don't forget that for a starting price of around $150 will be required for a PCI-e 4K graphics adapter<https://www.pbtech.co.nz/product/VGAGBV11032/Gigabyte-GeForce-GT1030-2GB-GD…>. cheers, Ian.

Cloudflare, Google Chrome, and Firefox Add HTTP/3 Support
by Peter Reutemann 27 Sep '19

27 Sep '19

'HTTP/3, the next major iteration of the HTTP protocol, is getting a big boost today with support added in Cloudflare, Google Chrome, and Mozilla Firefox. From a report: Starting today, Cloudflare announced that customers will be able to enable an option in their dashboards and turn on HTTP/3 support for their domains. That means that whenever users visit a Cloudflare-hosted website from an HTTP/3-capable client, the connection will automatically upgrade to the new protocol, rather than being handled via older versions. On the browser side, Chrome Canary added support for HTTP/3 earlier this month. Users can enable it by using the Chrome command-line flags of "--enable-quic --quic-version=h3-23". In addition, Mozilla too announced it would roll out support for HTTP/3. The browser maker is scheduled to ship HTTP/3 in an upcoming Firefox Nightly version later this fall.' -- source: https://news.slashdot.org/story/19/09/26/1710239 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/

Why So Many Apps Are Asking To Use Bluetooth on iOS 13
by Peter Reutemann 26 Sep '19

26 Sep '19

'Apple's new iOS 13 update adds a new privacy measure that requires apps to get your consent in order to use your device's Bluetooth. From a report: After installing the latest version of iOS, trust me when I say you'll be surprised by the number of apps asking for Bluetooth permission the next time you open them. Some might seem very strange (like Dunkin' Donuts in my case), but others probably won't make you think twice about giving the thumbs-up. The reason Apple implemented this is because Bluetooth has enabled companies to sneakily track your location over Bluetooth by using beacons in stores, shopping malls, and even on popular city streets if they're placed within range of a place you'd walk by. This is entirely separate from your iPhone's location privacy settings, which makes it seem all the more underhanded. A beacon is very easily able to detect your device's Bluetooth chip and log that with a retailer or some other app on your phone. So getting more strict about Bluetooth is a good move by Apple to prevent unwanted tracking of its customers. Similarly, the company is also getting even more transparent about location, showing you on a map how often and where apps have recorded your position. This prompt is much easier to understand, and will probably startle people into slimming down the list of apps that can monitor where they are. As it should!' -- source: https://apple.slashdot.org/story/19/09/26/1928204 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/

High-severity vulnerability in vBulletin is being actively exploited

The /e/ Google-Free, Pro-Privacy Android Clone Is Now Available
by Peter Reutemann 26 Sep '19

26 Sep '19

'Gael Duval, creator of the popular early Linux distribution, Mandrake Linux, wanted a smartphone, which was open source, would run a wide variety of popular software, and protect your privacy. His answer was the Android-based /e/ operating system and smartphones. While it's still in beta, both its code and refurbished Samsung phones running it are now available. Duval's approach hasn't been to reinvent the mobile operating system wheel, but instead to clean up Android of its Google privacy-invading features and replace them with privacy-respecting one, in which, as Duval said in an interview, "Your data is your data." To do this, he's started with LineageOS. This is an Android-based operating system, which is descended from the failed CyanogenMod Android fork. According to Duval, the /e/ operating system is a Lineage OS fork. It also blends in features from the Android Open Source Project (AOSP) 7, 8, and 9 source-code trees. In the /e/ OS all Google services have been removed and replaced with MicroG services. MicroG replaces Google's libraries with purely open-source implementations without hooks to Google's services. This includes libraries and apps which provide Google Play, Maps, Geolocation, and Messaging services for the Android applications when they need them. What this means is that you can run some Android apps, which normally only work on a fully Google-enabled Android phone on an /e/ phone. These compatible apps are available via the /e/ app store. The /e/ platform also comes with its own services, the report notes. For example, its search program uses Qwant, a popular, privacy-first European-based search engine, and for cloud storage, you get /e/'s own cloud, which is based on the open-source NextCloud. You can download and install /e/ on 85 different smartphone models. You can also buy an /e/ phone today if you're in the EU.' -- source: https://linux.slashdot.org/story/19/09/25/2129247 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/

Developer Made an Ad Blocker That Works On Podcasts and Radio
by Peter Reutemann 25 Sep '19

25 Sep '19

'Meet AdBlock Radio, an adblocker for live radio streams and podcasts. Its creator, Alexandre Storelli, told Motherboard he hopes to help companies "develop alternative business models for radio and podcast lovers that do not want ads." "Ads exploit the weaknesses of many defenseless souls," Storelli told Motherboard. "Ads dishonestly tempt people, steal their time and promise them a higher social status. Blocking them will be a relieving experience for many." Most audio ads exploit "auditory artifacts" to produce an ad that can't be ignored or tuned out because it feels louder than it actually is -- this has gotten so bad that there has actually been a "sonic arms race" where ads have been made increasingly louder over the years. "Adblock Radio detects audio ads with machine-learning and Shazam-like techniques," Storelli wrote about the project. He said he's been working on it for more than three years and that it uses techniques such as speech recognition, acoustic fingerprinting, and machine learning to detect known ad formats. It uses a crowdsourced database of ads and "acoustic fingerprinting," which converts audio features into a series of numbers that can be combed by an algorithm. Storelli has made Adblock Radio open-source and given detailed instructions on how to build on it, integrate it into user devices, and deploy it in a way that pressures radio stations (and podcasts) to self-regulate the quality of their ads.' -- source: https://entertainment.slashdot.org/story/19/09/25/2056215 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/

Android 10 Go Edition Improves Speed and Security For Low-cost Phones
by Peter Reutemann 25 Sep '19

'Android Go has made smartphones more accessible by focusing on lower-cost devices, but it's frequently pokey and sometimes insecure -- not a great introduction to modern mobile tech.

From a report: The scaled-back version of Android 10 puts a strong focus on speed, with faster and more memory-efficient app switching as well as launching that's 10 percent faster than in Android 9 Go. It should be more reliable, too. For some, data protection may be the real star of the show. Android 10 Go edition includes a new Adiantum encryption system that should secure data without affecting performance or requiring special hardware. You won't have to worry that your sensitive info is vulnerable simply because you bought an entry-level device.' -- source: https://mobile.slashdot.org/story/19/09/25/1648239 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/

Quantum Computers Are Analog Computers
by Lawrence D'Oliveiro 25 Sep '19

25 Sep '19

Google continues to experiment with quantum computing <https://arstechnica.com/science/2019/09/paper-leaks-showing-a-quantum-compu…>. This latest result (albeit preliminary) sounds impressive: But that seriously understates what's going on here. Every calculation that's done on a quantum computer will end up being a measurement of a quantum system. And in this case, there is simply no way to get that probability distribution using a classical computer. With this system, we can get it in under 10 minutes, and most of that time is spent in processing that doesn't involve the qubits. As the researchers put it, "To our knowledge, this experiment marks the first computation that can only be performed on a quantum processor." but it is still just reinforcing the point I made earlier <https://list.waikato.ac.nz/hyperkitty/list/wlug(a)list.waikato.ac.nz/thread…>, that quantum computers are just a reboot of the old idea of “analog” computers. These are able to do fast simulations of physical systems (in this case, a quantum probability distribution), to limited precision. But they continue to be useless for number-theoretic calculations, such as factoring large integers. Or code cracking.

Linux Foundation Exec Believes Edge Computing Will Be More Important Than Cloud Computing
by Peter Reutemann 23 Sep '19

23 Sep '19

'Once upon a time, back when we all had mainframes and then servers in our offices, we had edge computing. Our compute power was literally down the hall. Then, along came the cloud, and all that changed. Computers were hundreds of miles but milliseconds away. Now, with the rise of IoT, 5G, and our never-satisfied need for speed, edge computing is coming back with a vengeance. Indeed, at his keynote at Open Networking Summit in Belgium, Arpit Joshipura, The Linux Foundation's general manager of networking, said "edge computing will overtake cloud computing" by 2025. When Joshipura is talking about edge computing, he means compute and storage resources that are five to 20 milliseconds away. He also means edge computing should be an open, interoperable framework. This framework should be independent of hardware, silicon, cloud, or operating system. Open-edge computing should also work with any edge-computing use case: Internet of Things (IoT) edge, a telecom edge, cloud edge, or enterprise edge, whatever, "Our goal here is to unify all of these."

GNU's Former Kernel Maintainer Shares 'A Reflection on the Departure of Richard Stallman'
by Peter Reutemann 22 Sep '19

22 Sep '19

'Thomas Bushnell, BSG, founded GNU's official kernel project, GNU Hurd, and maintained it from 1990 through 2003. This week on Medium he posted "a reflection on the departure of RMS." There has been some bad reporting, and that's a problem. While I have not waded through the entire email thread Selam G. has posted, my reaction was that RMS did not defend Epstein, and did not say that the victim in this case was acting voluntarily. But it's not the most important problem. It's not remotely close to being the most important problem. This was an own-goal for RMS. He has had plenty of opportunities to learn how to stfu when that's necessary. He's responsible for relying too much on people's careful reading of his note, but even that's not the problem. He thought that Marvin Minsky was being unfairly accused. Minsky was his friend for many many years, and I think he carries a lot of affection and loyalty for his memory. But Minsky is also dead, and there's plenty of time to discuss at leisure whatever questions there may be about his culpability. RMS treated the problem as being "let's make sure we don't criticize Minsky unfairly", when the problem was actually, "how can we come to terms with a history of MIT's institutional neglect of its responsibilities toward women and its apparent complicity with Epstein's crimes". While it is true we should not treat Minsky unfairly, it was not -- and is not -- a pressing concern, and by making it his concern, RMS signaled clearly that it was much more important to him than the question of the institution's patterns of problematic coddling of bad behavior. And, I think, some of those focusing themselves on careful parsing of RMS's words are falling into the same pitfall as he.... Minsky was RMS's protector for a long long time. He created the AI Lab, where I think RMS found the only happy home he ever knew. He kept the rest of the Institute at bay and insulated RMS from attack (as did other faculty that also had befriended RMS). I was around for most of the 90s, and I can confirm the unfortunate reality that RMS's behavior was a concern at the time, and that this protection was itself part of the problem... Bushnell also calls Stallman "a tragic figure. He is one of the most brilliant people I've met, who I have always thought desperately craved friendship and camaraderie, and seems to have less and less of it all the time. This is all his doing; nobody does it to him. But it's still very sad. As far as I can tell, he believes his entire life's work is a failure..." But Bushnell concludes that "It is time for the free software community to leave adolescence and move to adulthood, and this requires leaving childish tantrums, abusive language, and toxic environments behind."' -- source: https://news.slashdot.org/story/19/09/21/0253227 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/

Debian May Need To Re-Evaluate Its Interest In 'Init System Diversity'
by Peter Reutemann 22 Sep '19

22 Sep '19

'"Debian Project Leader Sam Hartman has shared his August 2019 notes where he outlines the frustrations and issues that have come up as a result of init system diversity with some developers still aiming to viably support systemd alternatives within Debian," reports Phoronix: Stemming from elogind being blocked from transitioning to testing and the lack of clarity into that, Hartman was pulled in to try to help mediate the matter and get to the bottom of the situation with a lack of cooperation between the elogind and systemd maintainers for Debian as well as the release team. Elogind is used by some distributions as an implementation of systemd's logind, well, outside of systemd as a standalone daemon. Elogind is one of the pieces to the puzzle for trying to maintain a modern, systemd-free Linux distribution. Various issues were raised that are trying to be worked through albeit many Debian developers face time limitations and other factors like emotional exhaustion. Hartman noted in his August notes, "I think we may be approaching a point where we need to poll the project -- to have a GR and ask ourselves how committed we are to the different parts of this init diversity discussion. Reaffirming our support for sysvinit and elogind would be one of the options in any such GR. If that option passed, we'd expect all the maintainers involved to work together or to appoint and empower people who could work on this issue. It would be fine for maintainers not to be involved so long as they did not block progress. And of course we would hold the discussions to the highest standards of respect."' -- source: https://linux.slashdot.org/story/19/09/21/042213 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/

Phrase Of The Week: “Tab Bankruptcy”
by Lawrence D'Oliveiro 22 Sep '19

22 Sep '19

What happens when you accumulate a growing bunch of open pages in your browser, meaning to look at them in the next few days, but never get around to it? Until you have so many tabs open, you realize you will never have time to check them out, so you abandon them all and start again? That’s called “declaring tab bankruptcy”. And here <https://github.com/jsvine/tab-bankrupter> is a Chrome extension that lets you do that, while preserving pinned tabs, but saves a record of all the tabs you’ve abandoned. So, you know, you can change your mind and come back to them later ... Then you’ll probably want another extension to let you declare saved-bankruptcy bankruptcy, where you wipe all your bankruptcy saves and start again ...

A Novel Use For GitHub

Came across this GitHub repo <https://github.com/tewhalen/bmw_e30>, which doesn’t actually contain any code. Instead, the owner is using the issues feature to keep track of servicing items for his car. Why do it on a public server? Well, the guy is a BMW owner ...

At The Open-Core Summit
by Lawrence D'Oliveiro 20 Sep '19

20 Sep '19

A bunch of companies <https://www.theregister.co.uk/2019/09/20/open_source_companies_cloud/> have met to share a common annoyance: that big corporations like Amazon, Google and Microsoft are able to profit from their open-source software without giving anything back. I’m not sure what you can do about it, though. Attempts to impose more restrictive conditions on licences seem to have backfired. The AGPL seems to have been the only one of these efforts to have any legs, and I’m doubtful it has really achieved much.

German Interior Ministry Wants To Ensure “Digital Sovereignty”
by Lawrence D'Oliveiro 20 Sep '19

20 Sep '19

Germany wants to avoid having too much reliance on specific software/service vendors, like Microsoft and cloud suppliers <https://www.theregister.co.uk/2019/09/19/german_government_report_digital_s…>. How to deal with this? Answers suggested were * Negotiate new contracts with those same suppliers that get rid of the objectionable things, like telemetry * Diversify: stick with proprietary software, just get it from more suppliers * Use Open Source. Real-world results seem mixed? (Munich was cited as a “failure”). Also, Open Source software can end up acquired by proprietary vendors anyway. But then again, why should such acquisitions be such a big deal? Have they not heard of “forks”? Word I learned today: “Schmerzpunkt”.

How the Internet Archive is Waging War on Misinformation
by Peter Reutemann 19 Sep '19

19 Sep '19

'San Francisco-based non-profit is archiving billions of web pages in a bid to preserve web history. From a report: Since the 2016 US election, as fears about the power of fake news have intensified, the archive has stepped up its efforts to combat misinformation. At a time when false and ultra-partisan content is rapidly created and spread, and social media pages are constantly updated, the importance of having an unalterable record of who said what, when has been magnified. "We're trying to put in a layer of accountability," said founder Brewster Kahle. Mr Kahle founded the archive, which now employs more than 100 staff and costs $18m a year to run, because he feared that what was appearing on the internet was not being saved and catalogued in the same way as newspapers and books. The organisation is funded through donations, grants and the fees it charges third parties that request specific digitisation services. So far, the archive has catalogued 330bn web pages, 20m books and texts, 8.5m audio and video recordings, 3m images and 200,000 software programs. The most popular, public websites are prioritised, as are those that are commonly linked to. Some information is free to access, some is loaned out (if copyright laws apply) and some is only available to researchers. Curled up in a chair in his office after lunch, Mr Kahle lamented the combined impact of misinformation and how difficult it can be for ordinary people to access reliable sources of facts. "We're bringing up a generation that turns to their screens, without a library of information accessible via screens," said Mr Kahle. Some have taken advantage of this "new information system", he argued -- and the result is "Trump and Brexit." Having a free online library is crucial, said Mr Kahle, since "[the public is] just learning from whateverâ...âis easily available."' -- source: https://tech.slashdot.org/story/19/09/19/1858249 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/

Protocol found in webcams and DVRs is fueling a new round of big DDoSes
by Peter Reutemann 19 Sep '19

19 Sep '19

'Hackers have found a new way to amplify the crippling effects of denial-of-service techniques by abusing an improperly implemented tool found in almost 1 million network-connected cameras, DVRs, and other Internet-of-things devices. The technique abuses WS-Discovery, a protocol that a wide array of network devices use to automatically connect to one another. Often abbreviated as WSD, the protocol lets devices send user datagram protocol packets that describe the device capabilities and requirements over port 3702. Devices that receive the probes can respond with replies that can be tens to hundreds of times bigger. WSD has shipped with Windows since Vista and is one of the ways the operating system automatically finds network-based printers.' -- source: https://arstechnica.com/information-technology/2019/09/in-the-wild-ddoses-a… 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/
