Experts Find Serious Problems With Switzerland's Online Voting System
by Peter Reutemann 22 Feb '19

22 Feb '19

'Switzerland made headlines this month for the transparency of its internet voting system when it launched a public penetration test and bug bounty program to test the resiliency of the system to attack. But after source code for the software and technical documentation describing its architecture were leaked online last week, critics are already expressing concern about the system's design and about the transparency around the public test. Cryptography experts who spent just a few hours examining the leaked code say the system is a poorly constructed and convoluted maze that makes it difficult to follow what's going on and effectively evaluate whether the cryptography and other security measures deployed in the system are done properly. "Most of the system is split across hundreds of different files, each configured at various levels," Sarah Jamie Lewis, a former security engineer for Amazon as well as a former computer scientist for England's GCHQ intelligence agency, told Motherboard. "I'm used to dealing with Java code that runs across different packages and different teams, and this code somewhat defeats even my understanding." She said the system uses cryptographic solutions that are fairly new to the field and that have to be implemented in very specific ways to make the system auditable, but the design the programmers chose thwarts this. "It is simply not the standard we would expect," she told Motherboard. [...] It isn't just outside attackers that are a concern; the system raises the possibility for an insider to intentionally misconfigure the system to make it easier to manipulate, while maintaining plausible deniability that the misconfiguration was unintentional. "Someone could wire the thing in the wrong place and suddenly the system is compromised," said Lewis, who is currently executive director of the Open Privacy Research Society, a Canadian nonprofit that develops secure and privacy-enhancing software for marginalized communities. "And when you're talking about code that is supposed to be protecting a national election, that is not a statement someone should be able to make." "You expect secure code to be defensively written that would prevent the implementers of the code from wiring it up incorrectly," Lewis told Motherboard. But instead of building a system that doesn't allow for this, the programmers simply added a comment to their source code telling anyone who compiles and implements it to take care to configure it properly, she said. The online voting system was developed by Swiss Post, the country's national postal service, and the Barcelona-based company Scytl. "Scytl claims the system uses end-to-end encryption that only the Swiss Electoral Board would be able to decrypt," reports Motherboard. "But there are reasons to be concerned about such claims."' -- source: https://developers.slashdot.org/story/19/02/21/2227234 At least they had a public test to figure that out, rather than an actual election...

Millions of websites threatened by highly critical code-execution bug in Drupal
by Peter Reutemann 22 Feb '19

22 Feb '19

'Millions of sites that run the Drupal content management system run the risk of being hijacked until they're patched against a vulnerability that allows hackers to remotely execute malicious code, managers of the open source project warned Wednesday. CVE-2019-6340, as the flaw is tracked, stems from a failure to sufficiently validate user input, managers said in an advisory. Hackers who exploited the vulnerability could, in some cases, run code of their choice on vulnerable websites. The flaw is rated highly critical. "Some field types do not properly sanitize data from non-form sources," the advisory stated. "This can lead to arbitrary PHP code execution in some cases."' -- source: https://arstechnica.com/information-technology/2019/02/millions-of-websites… 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/

Severe Vulnerabilities Uncovered In Popular Password Managers
by Peter Reutemann 21 Feb '19

21 Feb '19

Not sure whether this also applies to the Linux/cross-platform versions... 'Independent Security Evaluators (ISE) published an assessment on Tuesday with the results of testing with several popular password managers, including LastPass and KeePass. The team said that each password management solution "failed to provide the security to safeguard a user's passwords as advertised" and "fundamental flaws" were found that "exposed the data they are designed to protect." The vulnerabilities were found in software operating on Windows 10 systems. In one example, the master password which users need to use to access their cache of credentials was stored in PC RAM in a plaintext, readable format. ISE was able to extract these passwords and other login credentials from memory while the password manager in question was locked. It may be possible that malicious programs downloaded to the same machine by threat actors could do the same. The report has summarized the main findings based on each password management solution. Here's what ISE had to say about LastPass and KeePass -- two of the most popular password managers available: "LastPass obfuscates the master password while users are typing in the entry, and when the password manager enters an unlocked state, database entries are only decrypted into memory when there is user interaction. However, ISE reported that these entries persist in memory after the software enters a locked state. It was also possible for the researchers to extract the master password and interacted-with password entries due to a memory leak." "KeePass scrubs the master password from memory and is not recoverable. However, errors in workflows permitted the researchers from extracting credential entries which have been interacted with. In the case of Windows APIs, sometimes, various memory buffers which contain decrypted entries may not be scrubbed correctly."' -- source: https://it.slashdot.org/story/19/02/21/070204 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/

Oracle Claims a Fighter of Pirated Apps is a Front For Ad Fraud
by Peter Reutemann 21 Feb '19

21 Feb '19

'A company that claims to combat app piracy is a pirate itself, according to a report Oracle released this week. From a report: Oracle claims the company, Tapcore, has been perpetrating a massive ad fraud on Android devices by infecting apps with software that ring up fake ad impressions and drain people's data. Based in The Netherlands, Tapcore works with developers to identify when apps are pirated and then enables developers to make money from those bootleg copies by serving ads. Oracle says that Tapcore's anti-piracy code was a Trojan horse that was generating fake mobile websites to trick ad serving platforms into paying them for non-existent ad inventory. "The code is delivering a steady stream of invisible video ads and spoofing domains," Dan Fichter, VP of software development at Oracle Data Cloud, tells Ad Age. "On all those impressions it looked like the advertiser was running ads on legitimate mobile websites. Not only were they not on a website, they were on an invisible web browser." On its website, Tapcore says it works with more than 3,000 apps, serving 150 million ad impressions a day. The apps whose pirated versions it has worked with include titles like "Perfect 365," "Draw Clash of Clans," "Vertex" and "Solitaire: Season 4," according to Oracle's report.' -- source: https://yro.slashdot.org/story/19/02/21/1238254 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 Researchers Say Software Alone Can't Mitigate Spectre Chip Flaws

'A group of researchers say that it will be difficult to avoid Spectre bugs in the future unless CPUs are dramatically overhauled.

The team of researchers -- including Ross McIlroy, Jaroslav Sevcik, Tobias Tebbi, Ben L Titzer and Toon Verwaest -- work on Chrome's V8 JavaScript engine.

A Psion Palmtop Successor Has Arrived and It Runs Android and Linux
by Peter Reutemann 21 Feb '19

21 Feb '19

'A lot of people probably remember the 1990s palmtop computers made by Psion fondly. The clamshell-design palmtops were pocketable, black and white, but had a working stylus and a fantastic tactile foldout QWERTY keyboard that you could type pretty substantial documents on or even write code with. A different company -- Planet Computers -- has now produced a spiritual successor to the old Psion palmtops called the Gemini PDA that is much like an old Psion but with the latest Android smartphone hardware in it and a virtually identical tactile keyboard. It can also dual boot to Linux (Debian, Ubuntu, Sailfish) alongside Android. The technical specs are a MediaTek deca-core processor, 4GB RAM, 64GB storage (plus microSD slot), 4G, 802.11c Wi-Fi, GPS, Bluetooth, eSIM support, and 4,220mAh battery. The screen measures in at 5.99-inches with a 2,160 x 1,080 (403ppi) resolution.

Samsung has given up developing new Blu-Ray players, and is going to stop selling them in the US altogether <https://arstechnica.com/gadgets/2019/02/samsung-says-it-will-stop-making-ne…>.

Linux Subsystem Files To Become Accessible via Windows File Explorer
by Peter Reutemann 19 Feb '19

19 Feb '19

'One of Windows Subsystem for Linux's more annoying tricks is it's hard to get at your Linux files from Windows. From a report: Oh, you can do it, but you take a real chance of ruining the files. To quote Microsoft, "DO NOT, under ANY circumstances, access, create, and/or modify files in your distro's filesystem using Windows apps, tools, scripts, consoles, etc." In the forthcoming Windows 10 April 2019 Update, aka Windows 10 19H1, this Linux file problem will finally be fixed. According to Craig Loewen, a Microsoft programming manger working on Windows Subsystem for Linux (WSL), "The next Windows update is coming soon and we're bringing exciting new updates to WSL with it!

How Not To Build A PC, And How Not To Respond To Those Criticizing You For It
by Lawrence D'Oliveiro 19 Feb '19

19 Feb '19

About four months ago, The Verge posted a video on its YouTube channel explaining the basics of building your own PC. Unfortunately, the video was full of mistakes, some small, some potentially more troublesome. Naturally this was pointed out in the comments. Also several other more techie-oriented channels responded with their own critique videos, some quite scathing. Rather than admit its mistake, the company decided to simply block comments for that video, and eventually take it down altogether. (Though not before it had accumulated a few thousand downvotes.) Now, within the last week or so, it has suddenly decided to go after those critique videos, and force them to be taken down on the basis of copyright infringement, because they contain extracts from the original item. Extracts which, under US fair use law, it was perfectly legal for them to include. Naturally, these heavy-handed attempts at censorship provoked a great deal of anger and protest, and the company has had to relent. If it was trying to downplay any lingering evidence of its previous embarrassment, this was absolutely not the way to do it. The phrase “Streisand Effect” immediately comes to mind, where an attempt by the eponymous celebrity to suppress pictures of the outside of her home, taken from public property, only caused them to be spread more widely. <https://www.youtube.com/results?search_query=the+verge+pc+build+takedown> Origin of the Streisand Effect: <https://www.techdirt.com/articles/20030624/1231228.shtml>

Inside the DNSpionage hacks that hijack domains at an unprecedented scale
by Peter Reutemann 18 Feb '19

18 Feb '19

'Since the beginning of the year, the US government and private security companies have been warning of a sophisticated wave of attacks that’s hijacking domains belonging to multiple governments and private companies at an unprecedented scale. On Monday, a detailed report provided new details that helped explain how and why the widespread DNS hijackings allowed the attackers to siphon huge numbers of email and other login credentials. The article, published by KrebsOnSecurity reporter Brian Krebs, said that, over the past few months, the attackers behind the so-called DNSpionage campaign have compromised key components of DNS infrastructure for more than 50 Middle Eastern companies and government agencies. Monday’s article goes on to report that the attackers, who are believed to be based in Iran, also took control of domains belonging to two highly influential Western services—the Netnod Internet Exchange in Sweden and the Packet Clearing House in Northern California. With control of the domains, the hackers were able to generate valid TLS certificates that allowed them to launch man-in-the-middle attacks that intercepted sensitive credentials and other data.' -- source: https://arstechnica.com/information-technology/2019/02/inside-the-dnspionag… 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/

RNZ Mediawatch--Geeks’ Gathering Goes Under The Radar
by Lawrence D'Oliveiro 15 Feb '19

15 Feb '19

Did you know that the annual linux.conf.au gathering was held in Christchurch last month? And that Linus Torvalds was there, wandering around the Canterbury University campus? Neither did I. Radio New Zealand’s Mediawatch program from a couple of weeks ago goes into the reasons why there was no media coverage of the event. Partly they might have been put off by some of the more esoteric and technical subjects being discussed. But in among them were some topics that should be considered more relevant to the “mainstream”, such as how automation could be doing away with many jobs being done by humans, leaving only the low-paying ones. The item includes an interview with NZOSS president Dave Lane, in which he incidentally mentions that Radio New Zealand’s online presence is built on Open Source, and that stuff.co.nz was, until recently, doing the same, and was also the one part of the Fairfax online media empire that was making money. Until that system was replaced with one based on expensive and proprietary Adobe products. And now they are not making nearly as much money. Coincidence? You be the judge. <https://www.radionz.co.nz/national/programmes/mediawatch/audio/2018680533/g…> By the way, it seems they have stopped making Ogg versions of items like these available for playback or download -- the links for the above one are only for an MP3 version. Also, I don’t agree that the distinction between “artificial intelligence” and “machine learning” is that clear-cut. I did a graduate course on AI back in the day, and it was already a pretty fuzzy concept back then. Except for one quite concise, mathematically-based definition I came across that appealed to me: “solving NP problems in polynomial time”.

The Second Navstar GPS Rollover Approaches

The US GPS* protocol represents times using a 10-bit field for the week number.

A second rollover is now approaching, as of April 6th (the first Saturday in April). Guess what’s going to happen this time ... <https://www.theregister.co.uk/2019/02/12/current_gps_epoch_ends/> *Seems the original official name “Navstar” has been dropped, and “GPS”, instead of being a generic term for such satellite-based navigation systems, is now the specific name of the US one.

Bruce Schneier: Blockchain And Trust
by Lawrence D'Oliveiro 12 Feb '19

12 Feb '19

Another thoughtful essay <https://www.schneier.com/blog/archives/2019/02/blockchain_and_.html> from the well-known computer-security guru: Trust is essential to society. As a species, humans are wired to trust one another. Society can't function without trust, and the fact that we mostly don't even think about it is a measure of how well trust works. .... Most blockchain enthusiasts have a unnaturally narrow definition of trust. They're fond of catchphrases like "in code we trust," "in math we trust," and "in crypto we trust." This is trust as verification. But verification isn't the same as trust. .... Any blockchain system will have to coexist with other, more conventional systems. Modern banking, for example, is designed to be reversible. Bitcoin is not. That makes it hard to make the two compatible, and the result is often an insecurity. Steve Wozniak was scammed out of $70K in bitcoin because he forgot this. .... Honestly, cryptocurrencies are useless. They're only used by speculators looking for quick riches, people who don't like government-backed currencies, and criminals who want a black-market way to exchange money.

Android Phones Can Be Hacked Remotely By Viewing Malicious PNG Image

'An innocent-looking image -- sent either via the internet or text -- could open your Android phone up to hacking. "While this certainly doesn't apply to all images, Google discovered that a maliciously crafted PNG image could be used to hijack a wide variety of Androids -- those running Android Nougat (7.0), Oreo (8.0), and even the latest Android OS Pie (9.0)," reports CSO Online. From the report: The latest bulletin lists 42 vulnerabilities in total -- 11 of which are rated as critical. The most severe critical flaw is in Framework; it "could enable a remote attacker using a specially crafted PNG file to execute arbitrary code within the context of a privileged process." Although Google had no report of the security flaws being actively exploited, it remains to be seen if and how long it will take before attackers use the flaw for real-world attacks. Android owners were urged to patch as soon as security updates becomes available. But let's get real: Even if your Android still receives security updates, there's no telling how long it will be (weeks or months) before manufacturers and carriers get it together to push out the patches.

LibreOffice 6.2 Brings New Interfaces, Performance Improvements To the Open Source Office Suite
by Peter Reutemann 08 Feb '19

08 Feb '19

'New interface styles and feature improvements are available in version 6.2 of LibreOffice -- the most popular open-source office suite -- released Thursday by The Document Foundation. As with any software update, bug fixes and feature enhancements are present, making this release a significant upgrade, particularly for users coming from Microsoft Office, or working with files created with those programs. LibreOffice now supports SVG-based icons for toolbars in the Breeze, Colibre, and Elementary icon sets as an experimental feature, to better support HiDPI displays increasingly found in notebook PCs. The Elementary icon set was also improved significantly, adding a 32px PNG version, and fixing inconsistencies between the 16, 24, and 32px versions, as well as adding more icons across the set to prevent reverting to defaults.

Blender Wins Annie Award
by Lawrence D'Oliveiro 06 Feb '19

06 Feb '19

The “Annies” are the annual awards given out by the International Animated Film Society, aka ASIFA-Hollywood. As part of these, there is a special prize known as the Ub Iwerks award for technical advancement in the art of animation, named for the Disney animator who so famously brought Mickey Mouse to life, back in the day. This is only given out in any particular year when the judges feel that somebody deserves it. Well, the latest winner is none other than Blender, the open-source CG software. Past winners have included software, companies and people, but this appears to be the first time that a piece of Free software has been so honoured. <http://www.cgchannel.com/2018/12/blender-creator-ton-roosendaal-wins-annie-…> <https://www.blender.org/news/ton-roosendaal-and-blender-to-receive-asifa-ho…>

Attackers Can Track Kids' Locations Via Connected Watches
by Peter Reutemann 31 Jan '19

31 Jan '19

'A gamut of kids' GPS-tracking watches are exposing sensitive data involving 35,000 children -- including their location, in real time. Researchers from Pen Test Partners specifically took a look at the Gator portfolio of watches from TechSixtyFour. The Gator line had been in the spotlight in 2017 for having a raft of vulnerabilities, called out by the Norwegian Consumers Council in its WatchOut research. "A year on, we decided to have a look at the Gator watch again to see how their security had improved," said Vangelis Stykas, in a Tuesday posting. "Guess what: a train wreck. Anyone could access the entire database, including real-time child location, name, parents' details etc. Not just Gator watches either -- the same back end covered multiple brands and tens of thousands of watches." "At issue was an easy-to-exploit, severe privilege-escalation vulnerability: The system failed to validate that the user had the appropriate permission to take admin control," reports Threatpost. "An attacker with access to the watch's credentials simply needed to change the user level parameter in the backend to an admin designation, which would provide access to all account information and all watch information."

Hackers Are Passing Around a Megaleak of 2.2 Billion Records
by Peter Reutemann 31 Jan '19

31 Jan '19

'When hackers breached companies like Dropbox and LinkedIn in recent years -- stealing 71 and 117 million passwords, respectively -- they at least had the decency to exploit those stolen credentials in secret, or sell them for thousands of dollars on the dark web. Now, it seems, someone has cobbled together those breached databases and many more into a gargantuan, unprecedented collection of 2.2 billion unique usernames and associated passwords, and is freely distributing them on hacker forums and torrents, throwing out the private data of a significant fraction of humanity like last year's phone book. Earlier this month, security researcher Troy Hunt identified the first tranche of that mega-dump, named Collection #1 by its anonymous creator, a set of cobbled-together breached databases Hunt said represented 773 million unique usernames and passwords. Now other researchers have obtained and analyzed an additional vast database called Collections #2-5, which amounts to 845 gigabytes of stolen data and 25 billion records in all. After accounting for duplicates, analysts at the Hasso Plattner Institute in Potsdam, Germany, found that the total haul represents close to three times the Collection #1 batch.' -- source: https://tech.slashdot.org/story/19/01/31/1452201 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 Security Flaw Impacts 5G, 4G, and 3G Telephony Protocols
by Peter Reutemann 31 Jan '19

31 Jan '19

'A new vulnerability has been discovered in the upcoming 5G cellular mobile communications protocol. Researchers have described this new flaw as more severe than any of the previous vulnerabilities that affected the 3G and 4G standards. From a report: Further, besides 5G, this new vulnerability also impacts the older 3G and 4G protocols, providing surveillance tech vendors with a new flaw they can abuse to create next-gen IMSI-catchers that work across all modern telephony protocols. This new vulnerability has been detailed in a research paper named "New Privacy Threat on 3G, 4G, and Upcoming5G AKA Protocols," published last year. According to researchers, the vulnerability impacts AKA, which stands for Authentication and Key Agreement, a protocol that provides authentication between a user's phone and the cellular networks. The AKA protocol works by negotiating and establishing keys for encrypting the communications between a phone and the cellular network.' -- source: https://it.slashdot.org/story/19/01/31/1913237 Yeah, don't think so that I'm gonna upgrade from my stone tablets any time soon...

Criminals Are Tapping Into the Phone Network Backbone to Empty Bank Accounts
by Peter Reutemann 31 Jan '19

31 Jan '19

'Sophisticated hackers have long exploited flaws in SS7, a protocol used by telecom companies to coordinate how they route texts and calls around the world. Those who exploit SS7 can potentially track phones across the other side of the planet, and intercept text messages and phone calls without hacking the phone itself. From a report: This activity was typically only within reach of intelligence agencies or surveillance contractors, but now Motherboard has confirmed that this capability is much more widely available in the hands of financially-driven cybercriminal groups, who are using it to empty bank accounts. So-called SS7 attacks against banks are, although still relatively rare, much more prevalent than previously reported. Motherboard has identified a specific bank -- the UK's Metro Bank -- that fell victim to such an attack. The news highlights the gaping holes in the world's telecommunications infrastructure that the telco industry has known about for years despite ongoing attacks from criminals. The National Cyber Security Centre (NCSC), the defensive arm of the UK's signals intelligence agency GCHQ, confirmed that SS7 is being used to intercept codes used for banking. "We are aware of a known telecommunications vulnerability being exploited to target bank accounts by intercepting SMS text messages used as 2-Factor Authentication (2FA)," The NCSC told Motherboard in a statement. "Some of our clients in the banking industry or other financial services; they see more and more SS7- based [requests],â Karsten Nohl, a researcher from Security Research Labs who has worked on SS7 for years, told Motherboard in a phone call. "All of a sudden you have someone's text messages."' -- source: https://tech.slashdot.org/story/19/01/31/1925241 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 19.1: A sneaky popular distro skips upheaval, offers small upgrades
by Peter Reutemann 29 Jan '19

29 Jan '19

'While Ubuntu and Red Hat grabbed most of the Linux headlines last year, Linux Mint, once the darling of the tech press, had a relatively quiet year. Perhaps that's understandable with IBM buying Red Hat and Canonical moving back to the GNOME desktop. For the most part Linux Mint and its developers seemed to keep their heads down, working away while others enjoyed the limelight. Still, the Linux Mint team did churn out version 19, which brought the distro up to the Ubuntu 18.04 base. Mint 18.1 review: Forget about Wayland and get comfy with the command line While the new release may not have garnered mass attention, and probably isn't anyone's top pick for "the cloud," Linux Mint nevertheless remains the distro I see most frequently in the real world. When I watch a Linux tutorial or screen cast on YouTube, odds are I'll see the Linux Mint logo in the toolbar. When I see someone using Linux at the coffee shop, it usually turns out to be Linux Mint. When I ask fellow Linux users which distro they use, the main answers are Ubuntu... and Linux Mint. All of that is anecdotal, but it still points to a simple truth. For a distro that has seen little press lately, Linux Mint manages to remain popular with users. There's a good reason for that popularity: Linux Mint just works. It isn't "changing the desktop computer paradigm," or "innovating" in "groundbreaking" ways. The team behind Mint is just building a desktop operating system that looks and functions a lot like every other desktop operating system you've used, which is to say you'll be immediately comfortable and stop thinking about your desktop and start using it to do actual work. It's worth asking then, why switch from what I have now to Mint? Well, if you're happy with what you have now, stick with whatever it is. But if "it" happens to be Windows 10, well, hope you haven't tried to upgrade yet. Or if what you have now happens to be Ubuntu prior to 18.04 and you're dreading the upgrade to GNOME, suddenly Mint is worth a look. The project recently released version 19.1, which comes in three desktop flavors. There are two homegrown projects, Cinnamon (really Linux Mint's main desktop) and MATE, which started as a kind of Cinnamon light and has since become a very capable desktop in its own right. On top of those, there's also an XFCE version. Previously, there was also a KDE version of Linux Mint, but it was dropped last year because the KDE stack is different enough that all the bits that make Linux Mint, well, Minty, just didn't work with KDE. Diehard Mint and KDE fans can still get KDE working via a PPA, but it's not officially supported by Linux Mint.' -- source: https://arstechnica.com/gadgets/2019/01/linux-mint-19-1-a-sneaky-popular-di… 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 66 blocks auto-playing sound by default
by Peter Reutemann 29 Jan '19

'Few things are more annoying when browsing the internet than media that plays automatically, particularly if it makes noise. Mozilla is hip to this, and beginning in version 66, its Firefox browser will block automatically-playing audio by default. Websites won't be able to play audio without user interaction. On desktop, a notification pops up asking whether you want the website to play media automatically, while on mobile, media will play silently until you interact with the player. The beta version of Firefox 66 for Android is hitting the Play Store today. The APK of the beta isn't available just yet, but you can grab a nightly version of Firefox 66 on APK Mirror.

Microsoft Project Manager Says Mozilla Should Get Down From Its 'Philosophical Ivory Tower, ' Cease Firefox Development
by Peter Reutemann 29 Jan '19

29 Jan '19

'A Microsoft program manager has caused a stir on Twitter over the weekend by suggesting that Firefox-maker Mozilla should give up on its own rendering engine and move on with Chromium. "Thought: It's time for @mozilla to get down from their philosophical ivory tower. The web is dominated by Chromium, if they really 'cared' about the web, they would be contributing instead of building a parallel universe that's used by less than five percent?" wrote Kenneth Auchenberg, who builds web developer tools for Microsoft's Visual Studio Code. Auchenberg's post referred to Mozilla's response to Microsoft's announcement in December that it would scrap Edge's EdgeHTML rendering engine for Chromium's. The move will leave Firefox's Gecko engine as the only alternative to Chromium, which is used by Opera and dozens of other browsers. Few people agreed with Auchenberg, including engineers from both Mozilla and Chromium. Long-serving Mozillian Asa Dotzler was not impressed. "Just because your employer gave up on its own people and technology doesn't mean that others should follow," Dotzler replied to Auchenberg. Auchenberg clarified that he didn't want to see Mozilla vanish, but said it should reorganize into a research institution "instead of trying to to justify themselves with the 'protectors of the web' narrative."' -- source: https://news.slashdot.org/story/19/01/29/0016211 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 65 Arrives With Content Blocking Controls, and Support for WebP and AV1
by Peter Reutemann 29 Jan '19

29 Jan '19

'Firefox 65, the latest version of Mozilla's web browser, is now available for Windows, Mac, Linux, and Android platforms. The release brings simplified Content Blocking controls for Enhanced Tracking Protection, support for WebP image support with the Windows client getting an additional feature: support for AV1 format. From a report: Across all platforms, Firefox can now handle Google's WebP image format. WebP supports both lossy and lossless compression and promises the same image quality as existing formats at smaller file sizes. Firefox 65 for desktop brings redesigned controls for the Content Blocking section to let users choose their desired level of privacy protection. You can access it by either clicking on the small "i" icon in the address bar and clicking on the gear on the right side under Content Blocking or by going to Preferences, Privacy & Security, and then Content Blocking. Next, Firefox now supports AV1, the royalty-free video codec developed by the Alliance for Open Media. AV1 improves compression efficiency by more than 30 percent over the codec VP9, which it is meant to succeed. Lastly, Firefox's new Task Manager page (just navigate to about:performance or find it under "Other" in the main menu) is complete. Introduced in Firefox 64, Task Manager now reports memory usage for tabs and add-ons.' -- source: https://news.slashdot.org/story/19/01/29/1442237 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 Debian APT and PHP Pear Patches Highlight Vulnerability In Package Management Infrastructure?
by Peter Reutemann 27 Jan '19

27 Jan '19

'"Time and again, security experts and vendors alike will recommend to organizations and end users to keep software and systems updated with the latest patches," reports eWeek. "But what happens when the application infrastructure that is supposed to deliver those patches itself is at risk?" That's what open-source and Linux users were faced with this past week with a pair of projects reporting vulnerabilities. On January 22, the Debian Linux distribution reported a vulnerability in its APT package manager that is used by end users and organizations to get application updates. That disclosure was followed a day later, on January 23, with the PHP PEAR (PHP Extension and Application Repository) shutting down its primary website, warning that it was the victim of a data breach. PHP PEAR is a package manager that is included with many Linux distributions as part of the open-source PHP programming language binaries.... In the Debian APT case, a security researcher found a flaw, reported it, and the open-source project community responded rapidly, fixing the issue. With PHP PEAR issue, researchers with the Paranoids FIRE (Forensics, Incident Response and Engineering) Team reported that they discovered a tainted file on the primary PEAR website... Both PHP PEAR and Debian have issued updates fixing their respective issues. While both projects are undoubtably redoubling their efforts now with different security technologies and techniques, the simple fact is that the two issues highlight a risk with users trusting updating tools and package management systems.

Hope for Linux
by Ian Stewart 24 Jan '19

24 Jan '19

I am one of the volunteers that looks after the IT equipment at a community centre. The equipment includes 5 x PC's located in a room for the public to use. These PC's were originally donated with a single drive that has Windows 10. We add another drive which we make the Sata-0 drive, and move the cable for the Windows 10 drive so it is on the Sata-2 port. On the drive that we have added we install Ubuntu-Mate. By default, when the PC's power on, they boot up Ubuntu-Mate. Over the summer holidays the main users of these PC's are local children in the age range of 6 to 10 years old. I recently walked into the room which has the PC's and one of children recognised me as the IT repair man. The boy came over to me, and pointing at one of the PC's he said, "It's broken. It doesn't work." I looked across at the PC and saw that it was displaying a Windows 10 screen that appeared to be functioning OK, and noticed that there was nobody sitting using this computer. The other four PC's were running Ubuntu-Mate and children were busy using them. I said to the boy, "Yes it does look like its broken. I'll fix it." I proceeded to shutdown Windows 10, and found the Ubuntu-Mate drive had failed to the extent that it wasn't being recognised by the BIOS. I replaced the failed drive, installed Ubuntu-Mate from a USB stick, and told the boy it was fixed and he could use it again. I thought it was an encouraging sign that what these children perceive as a normal PC is one that is running Ubuntu-Mate and what they perceive as a broken PC is one that is running Windows 10. cheers, Ian

If you installed PEAR PHP in the last 6 months, you may be infected
by Peter Reutemann 24 Jan '19

24 Jan '19

'Officials with the widely used PHP Extension and Application Repository have temporarily shut down most of their website and are urging users to inspect their systems after discovering hackers replaced the main package manager with a malicious one. “If you have downloaded this go-pear.phar [package manager] in the past six months, you should get a new copy of the same release version from GitHub (pear/pearweb_phars) and compare file hashes,” officials wrote on the site’s blog. "If different, you may have the infected file.” The officials didn’t say when the hack of their Web server occurred or precisely what the malicious version of go-pear.phar did to infected systems. Initial indications, however, look serious. For starters, the advice applies to anyone who has downloaded the package manager in the past six months. That suggests the hack may have occurred in the timeframe of last July, and no one noticed either it or the tainted download until this week.' -- source: https://arstechnica.com/information-technology/2019/01/pear-php-site-breach… 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 Web Apps Can Turn Browser Extensions Into Backdoors
by Peter Reutemann 24 Jan '19

24 Jan '19

'"Threatpost has a link to some recent research about ways web pages can exploit browser extensions to steal information or write files," writes Slashdot reader jbmartin6. "Did we need another reason to be deeply suspicious of any browser extension? Not only do they spy on us for their makers, now other people can use them to spy on us as well. The academic paper is titled 'Empowering Web Applications with Browser Extensions' (PDF)." From the report: "An attacker [uses] a script that is present in a web application currently running in the user browser. The script either belongs to the web application or to a third party. The goal of the attacker is to interact with installed extensions, in order to access user sensitive information. It relies on extensions whose privileged capabilities can be exploited via an exchange of messages with scripts in the web application," researchers wrote. They added, "Even though content scripts, background pages and web applications run in separate execution contexts, they can establish communication channels to exchange messages with one another... APIs [are used] for sending and receiving (listening for) messages between the content scripts, background pages and web applications." The researcher behind the paper focused on a specific class of web extension called "WebExtensions API," a cross-browser extensions system compatible with major browsers including Chrome, Firefox, Opera and Microsoft Edge. After analyzing 78,315 extensions that used the specific WebExtension API, it found 3,996 that were suspicious. While it seems voluminous, they noted that research found a small number of vulnerable extensions overall, and that concern should be measured. However, "browser vendors need to review extensions more rigorously, in particular take into consideration the use of message passing interfaces in extensions."' -- source: https://it.slashdot.org/story/19/01/23/2256252 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 Free Software Evangelist Richard Stallman is Haunted by Stalin's Dream
by Peter Reutemann 23 Jan '19

23 Jan '19

'Richard Stallman recently visited Mandya, a small town about 60 miles from Bengaluru, India, to give a talk. On the sidelines, Indian news outlet FactorDaily caught up with Stallman for an interview. In the wide-ranging interview, Stallman talked about companies that spy on users, popular Android apps, media streaming and transportation apps, smart devices, DRM, software backdoors, subscription software, and Apple and censorship. An excerpt from the interview: If you are carrying a mobile phone, it is always tracking your movements and it could have been modified to listen to the conversations around you. I call this product Stalin's dream. What would Stalin have wanted to hand out to every inhabitant of the former Soviet Union? Something to track that person's movements and listen to the person's conservations. Fortunately, Stalin could not do it because the technology didn't exist. Unfortunately for us, now it does exist and most people have been pressured or lured into carrying around such a Stalin's dream device, but not me. I am suspicious of new digital technology. I expect it to have new malicious functionalities. It has happened so many times that I have learned to expect this, so I have always checked before I start using some new digital technology. I asked to find out what is nasty about it and I found out these two things. It was something like 20 years ago, and I decided it was my duty as a citizen to refuse, regardless of whatever convenience it might offer me. To surrender my freedom in this way was failing to defend a free society. This is why I do not have a portable phone. I refuse to carry a portable phone. I never have one and unless things change, I never will. I do use portable phones, lots of different ones. If I needed to call someone right now, I would ask one of you, "Could you please make a call for me?" If I am on a bus and it is late and I need to tell somebody that I am going to arrive late, there is always some other passenger in the bus who will make a call for me or send a text for me. Practically speaking, it is not that hard.' -- source: https://yro.slashdot.org/story/19/01/23/1759203 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 Proposes Changes To Chromium Browser That Will Break Content-Blocking Extensions, Including Various Ad Blockers
by Peter Reutemann 23 Jan '19

23 Jan '19

'"Google engineers have proposed changes to the open-source Chromium browser that will break content-blocking extensions, including various ad blockers," reports The Register. "The drafted changes will also limit the capabilities available to extension developers, ostensibly for the sake of speed and safety. Chromium forms the central core of Google Chrome, and, soon, Microsoft Edge." From the report: In a note posted Tuesday to the Chromium bug tracker, Raymond Hill, the developer behind uBlock Origin and uMatrix, said the changes contemplated by the Manifest v3 proposal will ruin his ad and content blocking extensions, and take control of content away from users. Manifest v3 refers to the specification for browser extension manifest files, which enumerate the resources and capabilities available to browser extensions. Google's stated rationale for making the proposed changes is to improve security, privacy and performance, and supposedly to enhance user control. But one way Google would like to achieve these goals involves replacing the webRequest API with a new one, declarativeNetRequest. The webRequest API allows extensions to intercept network requests, so they can be blocked, modified, or redirected. This can cause delays in web page loading because Chrome has to wait for the extension. In the future, webRequest will only be able to read network requests, not modify them. The declarativeNetRequest allows Chrome (rather than the extension itself) to decide how to handle network requests, thereby removing a possible source of bottlenecks and a potentially useful mechanism for changing browser behavior. The report notes that Adblock Plus "should still be available" since "Google and other internet advertising networks apparently pay Adblock Plus to whitelist their online adverts."

The most popular applications have amassed hundreds of millions of installs between them worldwide, yet there seems to be very little attention paid to the companies behind them, and very little scrutiny done on behalf of the marketplaces hosting them. We investigated the top free VPN apps in the App Store and Google Play Store. We found that very few of these hugely popular apps do anywhere near enough to deserve the trust of those looking to protect their privacy online. We recorded the top 20 free apps in the search results for "VPN" in the App and Play Store for UK and US locales. In total, these applications have been downloaded 80 million times from Google and 4 million times each month from Apple. Our investigation discovered that over half of the top free VPN apps either have Chinese ownership or are actually based in China, which has aggressively clamped down on VPN services in recent years and maintains an iron grip on the internet within its borders. Furthermore, we found the majority of these apps have insufficient formal privacy protections and non-existent user support.' -- source: https://yro.slashdot.org/story/19/01/21/1425201 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 WordPress Plugin WPML Hacked By Angry Former Employee
by Peter Reutemann 20 Jan '19

20 Jan '19

'A very popular WordPress plugin was hacked over the weekend after a hacker defaced its website and sent a mass message to all its customers revealing the existence of supposed unpatched security holes. From a report: In a follow-up mass email, the plugin's developers blamed the hack on a former employee, who also defaced their website. The plugin in question is WPML (or WP MultiLingual), the most popular WordPress plugin for translating and serving WordPress sites in multiple languages. According to its website, WPML has over 600,000 paying customers and is one of the very few WordPress plugins that is so reputable that it doesn't need to advertise itself with a free version on the official WordPress.org plugins repository. But on Saturday, ET timezone, the plugin faced its first major security incident since its launch in 2007. The attacker, which the WPML team claims is a former employee, sent out a mass email to all the plugin's customers.' -- source: https://tech.slashdot.org/story/19/01/20/2156231 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/

Collection 1 Data Breach Exposes More Than 772 Million Email Addresses
by Peter Reutemann 17 Jan '19

17 Jan '19

'A collection of almost 773 million unique email addresses and just under 22 million unique passwords were exposed on cloud service MEGA. Security researcher Troy Hunt said the collection of data, dubbed Collection #1, totaled over 12,000 separate files and more than 87GB of data. ZDNet reports: "What I can say is that my own personal data is in there and it's accurate; right email address and a password I used many years ago," Hunt wrote. "In short, if you're in this breach, one or more passwords you've previously used are floating around for others to see." Some passwords, including his own, have been "dehashed", that is converted back to plain text. Hunt said he gained the information after multiple people reached out to him with concerns over the data on MEGA, with the Collection #1 dump also being discussed on a hacking forum. "The post on the forum referenced 'a collection of 2000+ dehashed databases and Combos stored by topic' and provided a directory listing of 2,890 of the files," Hunt wrote. The collection has since been removed.

Mozilla Kills Its Experimental Firefox Test Pilot Program 3 Years After Launch
by Peter Reutemann 16 Jan '19

16 Jan '19

'Mozilla has announced that it is closing Firefox Test Pilot, an experimental program it launched three years ago. Firefox Test Pilot allowed users to try out potential new built-in Firefox features to understand if they are popular with users. The company says the program was used by an average of 100,000 daily users. A report adds: It's worth noting here that Test Pilot is separate from the various beta versions of Firefox, which are early iterations designed to fine-tune features intended for the prime-time Firefox. Test Pilot, on the other hand, is more about Mozilla dipping its toes in the water to see whether a new feature is worth pursuing at all in the main version of the app, or even as a standalone product. Ultimately, it allows Firefox developers to take bigger risks with their ideas.' -- source: https://news.slashdot.org/story/19/01/16/1752250 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/

From a report: As detailed in a video published on Sunday, the computer mouse computer consists of a 3d-printed mouse, a Raspberry Pi microcontroller, a small keyboard, and a handful of components that were taken from a normal computer mouse. "Even though the screen is attached to the mouse, the sensitivity of the mouse makes it not that hard to follow along with what is happening on the screen," Electronic Grenade said in the video.

Robocall -- New Kind Of Scammer?
by Lawrence D'Oliveiro 12 Jan '19

12 Jan '19

I just received an odd phone call which just played a (somewhat muffled and over-compressed) recorded message saying something like “This is Spark NZ informing you that your internet service is going to be terminated. For further information press 1, or press 2 for other queries.” After a few seconds, during which I did nothing, it hung up. I think I may have received a similar call maybe 2-3 weeks ago, because I heard a voice speaking on top of my recorded voice telling the caller to leave a message, but I was too far away at the time to make out what was being said.

Malware Found Preinstalled On Some Alcatel Smartphones
by Peter Reutemann 11 Jan '19

11 Jan '19

'A weather app that comes preinstalled on Alcatel smartphones contained malware that surreptitiously subscribed device owners to premium phone numbers behind their backs. The app, named "Weather Forecast-World Weather Accurate Radar," was developed by TCL Corporation, a Chinese electronics company that among other things owns the Alcatel, BlackBerry, and Palm brands. The app is one of the default apps that TCL installs on Alcatel smartphones, but it was also made available on the Play Store for all Android users --where it had been downloaded and installed more than ten million times. But at one point last year, both the app included on some Alcatel devices and the one that was available on the Play Store were compromised with malware. How the malware was added to the app is unclear. TCL has not responded to phone calls requesting comment made by ZDNet this week. The app reportedly harvested users' data and sent it to China. It collected geographic locations, email addresses, and IMEI codes, which it sent back to TCL. Upstream, a UK-based mobile security firm, also found that "the malicious code hidden inside the app would also attempt to subscribe users to premium phone numbers that incurred large charges on users' phone bills," reports ZDNet. "All in all, the company says it detected and blocked over 27 million transaction attempts across seven markets, which would have created losses of around $1.5 million to phone owners if they hadn't been blocked." Upstream notes that most of the behavior they've seen originated only from two types of smartphones: Pixi 4 and A3 Max models.' -- source: https://it.slashdot.org/story/19/01/10/2117234 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 systemd Affected by Memory Corruption Vulnerabilities, No Patches Yet
by Peter Reutemann 10 Jan '19

10 Jan '19

'Major Linux distributions are vulnerable to three bugs in systemd, a Linux initialization system and service manager in widespread use, California-based security company Qualys said late yesterday. From a report: The bugs exist in 'journald' service, tasked with collecting and storing log data, and they can be exploited to obtain root privileges on the target machine or to leak information. No patches exist at the moment. Discovered by researchers at Qualys, the flaws are two memory corruption vulnerabilities (stack buffer overflow - CVE-2018-16864, and allocation of memory without limits - CVE-2018-16865) and one out-of-bounds error (CVE-2018-16866). They were able to obtain local root shell on both x86 and x64 machines by exploiting CVE-2018-16865 and CVE-2018-16866. The exploit worked faster on the x86 platform, achieving its purpose in ten minutes; on x64, though, the exploit took 70 minutes to complete. Qualys is planning on publishing the proof-of-concept exploit code in the near future, but they did provide details on how they were able to take advantage of the flaws.' -- source: https://linux.slashdot.org/story/19/01/10/1759253 BTW This is an FYI, not a reason to start a flame war again...

New Tool Automates Phishing Attacks That Bypass 2FA
by Peter Reutemann 09 Jan '19

09 Jan '19

'A new penetration testing tool published at the start of the year by a security researcher can automate phishing attacks with an ease never seen before and can even blow through login operations for accounts protected by two-factor authentication (2FA). From a report: Named Modlishka --the English pronunciation of the Polish word for mantis -- this new tool was created by Polish researcher Piotr Duszynski. Modlishka is what IT professionals call a reverse proxy, but modified for handling traffic meant for login pages and phishing operations. It sits between a user and a target website -- like Gmail, Yahoo, or ProtonMail. Phishing victims connect to the Modlishka server (hosting a phishing domain), and the reverse proxy component behind it makes requests to the site it wants to impersonate. The victim receives authentic content from the legitimate site --let's say for example Google -- but all traffic and all the victim's interactions with the legitimate site passes through and is recorded on the Modlishka server.' -- source: https://it.slashdot.org/story/19/01/09/1817234 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/

Bash-5.0 release available
by Peter Reutemann 08 Jan '19

08 Jan '19

'This release fixes several outstanding bugs in bash-4.4 and introduces several new features. The most significant bug fixes are an overhaul of how nameref variables resolve and a number of potential out-of-bounds memory errors discovered via fuzzing. There are a number of changes to the expansion of $@ and $* in various contexts where word splitting is not performed to conform to a Posix standard interpretation, and additional changes to resolve corner cases for Posix conformance. The most notable new features are several new shell variables: BASH_ARGV0, EPOCHSECONDS, and EPOCHREALTIME. The `history' builtin can remove ranges of history entries and understands negative arguments as offsets from the end of the history list. There is an option to allow local variables to inherit the value of a variable with the same name at a preceding scope. There is a new shell option that, when enabled, causes the shell to attempt to expand associative array subscripts only once (this is an issue when they are used in arithmetic expressions). The `globasciiranges' shell option is now enabled by default; it can be set to off by default at configuration time. There are a few incompatible changes between bash-4.4 and bash-5.0. The changes to how nameref variables are resolved means that some uses of namerefs will behave differently, though I have tried to minimize the compatibility issues. By default, the shell only sets BASH_ARGC and BASH_ARGV at startup if extended debugging mode is enabled; it was an oversight that it was set unconditionally and caused performance issues when scripts were passed large numbers of arguments.' -- source: http://lists.gnu.org/archive/html/bug-bash/2019-01/msg00063.html 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/

DuckDuckGo Denies Using Fingerprinting To Track Its Users

Sony Appears To Be Blocking Kodi On Its Recent Android TVs
by Peter Reutemann 08 Jan '19

'Several reports indict that at least some of Sony's recent Android TVs are actively blocking Kodi, the open-source, cross-platform streaming and media player that allows you to access and play local, network, and remote content. Android Police reports: The official Kodi project Twitter account pointed out Sony's deficiency a couple of days ago, but reports on the Kodi forums of issues installing and running the app from the Play Store go even further back to last year. A handful of affected enthusiasts believe they have discovered the cause of the problem: Sony seems to be blocking the package ID for the app from being installed/run. Supporting this theory is the fact that recompiling the app from scratch with a different ID allows it to work.

Hi everyone I finally have all the room bookings for 2019 sorted (the guys doing the bookings are overworked and understaffed due to holidays). The university changed its policy around providing rooms on holiday from a "we'll coordinate with security" to a "should not be allowed".

Here's the complete list of meetings for 2019, for those that don't use meetup.com: Jan 21 -- 3rd Monday Feb 25 Mar 25 Apr 15 -- 3rd Monday May 27 Jun 24 Jul 22 Aug 26 Sep 23 Oct 21 -- 3rd Monday Nov 25 Here is the link to our meetup.com community page: https://www.meetup.com/WaikatoLinuxUsersGroup/ 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 For Cars: Tesla Isn't The Only Automaker Running Linux Under the Hood
by Peter Reutemann 06 Jan '19

06 Jan '19

'ZDNet reports that by 2020, "many, if not most, new cars will be running with Linux." While some companies, like Tesla, run their own homebrew Linux distros, most rely on Automotive Grade Linux (AGL). AGL is a collaborative cross-industry effort developing an open platform for connected cars with over 140 members... Its membership includes Audi, Ford, Honda, Mazda, Nissan, Mercedes, Suzuki, and the world's biggest automobile company: Toyota. Why? "Automakers are becoming software companies, and just like in the tech industry, they are realizing that open source is the way forward," said Dan Cauchy, AGL's executive director, in a statement. Car companies know that while horsepower sells, customers also want smart infotainment systems, automated safe drive features, and, eventually, self-driving cars. Linux and open-source company can give them all of that. The AGL's goal is to develop an open-source, common platform for infotainment systems: The Unified Code Base (UCB). This is a Linux distribution and open-source software platform for car infotainment, telematics, and instrument cluster applications... The AGL's hope is that this will serve as a de facto industry standard. It's well on its way. Yesterday Hyundai announced that they were also joining both the AGL effort and the Linux Foundation.' -- source: https://tech.slashdot.org/story/19/01/05/1928205 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/

Eben Upton Remembers The Years Before the First Raspberry Pi
by Peter Reutemann 06 Jan '19

06 Jan '19

'Tech Republic re-visits the story of the earliest attempts to build the Raspberry Pi, and the dramatic launch of a quest "to rekindle the curiosity about computing in a generation immersed in technology but indifferent to how it worked." [T]he dominant computers -- games consoles and later tablets and smartphones -- no longer offered an invitation to create, but rather to consume. Eben Upton recalls a bonfire party in 2007 where an 11-year-old boy told him he wanted to be an electrical engineer, and his disappointment at realizing the boy didn't have access to a computer he could program on. "I said, 'Oh, what computer have you got?'. He said, 'I've got a Nintendo Wii'. And there was just that awful feeling about there being a kid who was excited, a kid who was showing concrete interest in our profession, and who didn't have access to a programmable computer, a computer of any sort. He just had a games console." At this time Upton was working as a system-on-a-chip architect at chip designer Broadcom, and realized he had the skills to try to halt this drift away from computers that encouraged users to code. Upton describes the Raspberry Pi as "a very conscious attempt" to bring back the easily programmable home computers that he remembered as a child in the 1980s -- and he was gratified at its success. "Even early on you started to see those pictures of kids lying on the living room floor, looking up at the TV with Raspberry Pi plugged into it, the same way we used to." It was named "Pi" because it booted into a version of Python, and Raspberry because "There's a lot of fruit-named computer companies, and the 'blowing a raspberry' thing was also deliberate." It's gone on to become the world's third best-selling general-purpose computer.' -- source: https://developers.slashdot.org/story/19/01/05/2031219 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/

Mickey Mouse Will Be Public-Domain Soon; But What Will It Mean?
by Lawrence D'Oliveiro 03 Jan '19

03 Jan '19

Wonder of wonders, there has been no followup to the Sonny Bono Copyright Term Extension Act of 1998 <https://arstechnica.com/tech-policy/2019/01/a-whole-years-worth-of-works-ju…>. That means more and more interesting things are going to fall into the public domain from this year onwards. However, things are not going to be simple: the original incarnation of Walt Disney’s Mickey Mouse will be in the public domain after 2024, but later versions will still be under copyright, and the trademarks will also continue to be in effect. How will that work? Probably in the same way that “intellectual property” usually works: the one with the biggest legal budget wins.

Examples Of How Not To Code

Presenting the “Damn Vulnerable Serverless Application” <https://www.theregister.co.uk/2019/01/03/damn_vulnerable_serverless_applica…>, the latest in a line of “damn vulnerable” apps that are chock-full of deliberately-introduced security vulnerabilities. My worry about this sort of thing is the mindless-copy-and-paste crowd. We already see the effects of posting sample code with error-checking omitted “just to keep things simple”, along with exhortations to use it only as a guide, not to be slavishly copied; such exhortations are routinely ignored. From there, it seems only a small step to completely miss the context of such counterexample code, and actually use it as something to be followed.

Mozilla Thunderbird Outlines Plans For 2019: Addressing UI Lags, Performance Issues; Improved 3rd-Party Email Integration, Encryption Usability
by Peter Reutemann 02 Jan '19

02 Jan '19

'For years, Mozilla has largely neglected development of Thunderbird, an email client it owns. But the company, which grew its team to eight staff last year, says it plans to address most of the issues that users have complained about and add six more people to Thunderbird staff this year, it said in a blog post. In the blog post Wednesday, the company said: Our hires are already addressing technical debt and doing a fair bit of plumbing when it comes to Thunderbird's codebase. Our new hires will also be addressing UI-slowness and general performance issues across the application. This is an area where I think we will see some of the best improvements in Thunderbird for 2019, as we look into methods for testing and measuring slowness -- and then put our engineers on architecting solutions to these pain points. Beyond that, we will be looking into leveraging new, faster technologies in rewriting parts of Thunderbird as well as working toward a multi-process Thunderbird. [...] For instance, one area of usability that we are planning on addressing in 2019 is integration improvements in various areas. One of those in better Gmail support, as one of the biggest email providers it makes sense to focus some resources on this area. We are looking at addressing Gmail label support and ensuring that other features specific to the Gmail experience translate well into Thunderbird. We are looking at improving notifications in Thunderbird, by better integrating with each operating system's built-in notification system.

GIMP Developers Outline Plan For 2019
by Peter Reutemann 02 Jan '19

02 Jan '19

'The GIMP developers on Wednesday published a blog post in which they look back at the year 2018 (release of GIMP 2.10) and outline the things that they intend to get around this year. From the post: We expect to be shipping 2.10.x updates throughout 2019, starting with the version 2.10.10 currently expected in January/February. This version will feature faster layer groups rendering, smart colorization with the Bucket Fill tool, and various usability improvements. We are also planning the first unstable release of GIMP that will have version 2.99.2, eventually leading up to version 3.0. The prerequisite for releasing that version will be the completion of the space invasion. ZeMarmot project (which can be supported on Patreon or Tipeee) is also planning to focus a bit more on better canvas interactions, as well as animation support improvements, starting from merging existing work. On the GEGL and babl front, we expect to continue working towards better CMYK support and performance.' -- source: https://developers.slashdot.org/story/19/01/02/1655210 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/

USB Type-C Authentication Program Launched
by Peter Reutemann 02 Jan '19

02 Jan '19

'With the arrival of USB-C a few years back, plugging into laptops, tablets and smartphones became even easier than before. But there are potential security risks. The USB Type-C Authentication Program launched today aims to address such issues. From a report: The new protocol from the USB Implementers Forum (USB-IF) can be used to validate the authenticity of a cable, charger or hardware at the moment of connection, and stop attacks in their tracks. The USB-IF has chosen DigiCert to operate registrations and certificate authority services for the new specification, which makes use of 128-bit cryptographic-based authentication for certificate format, digital signing, hash and random number generation. "USB Type-C Authentication gives OEMs the opportunity to use certificates that enable host systems to confirm the authenticity of a USB device or USB charger, including such product aspects as the descriptors, capabilities and certification status," said DigiCert in a press release. "This protects against potential damage from non-compliant USB chargers and the risks from maliciously embedded hardware or software in devices attempting to exploit a USB connection."' -- source: https://it.slashdot.org/story/19/01/02/2025207 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/

wget Command Stores Extended Attributes
by Lawrence D'Oliveiro 02 Jan '19

02 Jan '19

Here’s something I didn’t know: the “wget” command saves the URL where it got a downloaded file as an extended attribute of the file. This behaviour isn’t mentioned anywhere in the man page or in the info file, that I can find. Unfortunately, this can lead to a security issue where the URL includes confidential password details. And it appears other apps, like Chrome, do a similar thing. <https://www.theregister.co.uk/2019/01/02/wget_bug_fix/>

Banana Pi 24-Core ARM Server Running Ubuntu Breaks Cover
by Peter Reutemann 27 Dec '18

27 Dec '18

'ARM-based server processors have threatened to take on Intel in the data center for some time but not much has materialized thus far in terms of significant deployments. However, a new breed of low cost ARM server implementations may be in the works with a many-core platform called Banana Pi. The latest Banana Pi device being teased is something very different in the form of a 24-core ARM server that speculation suggests might be sold as a Banana Pi server board or as a finished server product. A video has surfaced that reportedly shows a 24-core ARM Cortex-A53 processor with 32GB of RAM, though the OS only sees 29.4GB of that RAM. The OS is Ubuntu 18.04.1 LTS with MATE desktop. Unless the processor used in this device is something unannounced, and that seems unlikely, the chip itself would likely be a SocioNext SC2A11. The same processor is used in the Linaro Developer Box. The demo shows the server fully loaded at 100% CPU utilization building a Linux kernel and reportedly the system also supports NVMe storage as well as TensorFlow workloads for machine learning. Not much else is known about the system at this time but it's an interesting development in the Linux server space to be sure.' -- source: https://hardware.slashdot.org/story/18/12/27/0556243 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 Does Not “Sell” Your Data, But ...

Seems a bunch of companies have had extra-privileged access to user data on Facebook, and they in turn supplied information about those users back to Facebook. This is how the “People You May Know” feature is able to make links like between different patients of the same psychiatrist, and other things equally dodgy ethically, if not downright illegal (or at least they should be). And this may be how Amazon was able to make a (spurious) association between a book reviewer and the book author, and disallow the review on that basis, just because the reviewer had previously followed the author on Facebook.

A key breakthrough came in 2012, when a team at the University of Toronto combined the “convolutional” neural network concept with a massive deployment of sheer computing power to leave its competitors in the dust in the “ImageNet” image-recognition competition that year. That team are now working at Google. Oh, and the recognition algorithms are now scoring better than many humans in some areas.

Well, now meet the, um, more “wild and woolly” side with the same mission: Archive Team <https://archiveteam.org/>. They describe themselves as ... a loose collective of rogue archivists, programmers, writers and loudmouths dedicated to saving our digital heritage. Since 2009 this variant force of nature has caught wind of shutdowns, shutoffs, mergers, and plain old deletions - and done our best to save the history before it's lost forever. Along the way, we've gotten attention, resistance, press and discussion, but most importantly, we've gotten the message out: IT DOESN'T HAVE TO BE THIS WAY. I just heard about them because they were trying to save all the X-rated blogs on tumblr.com before these disappeared, on orders of new owner Verizon.

MIPS Goes Open Source
by Peter Reutemann 18 Dec '18

18 Dec '18

'Junko Yoshida, writing for EETimes: Without question, 2018 was the year RISC-V genuinely began to build momentum among chip architects hungry for open-source instruction sets. That was then. By 2019, RISC-V won't be the only game in town. Wave Computing (Campbell, Calif.) announced Monday (Dec. 17) that it is putting MIPS on open source, with MIPS Instruction Set Architecture (ISA) and MIPS' latest core R6 available in the first quarter of 2019. Art Swift, hired by Wave this month as president of its MIPS licensing business, described the move as critical to accelerate the adoption of MIPS in an ecosystem. Going open source is "a big plan" that Wave CEO Derek Meyer, a MIPS veteran, has been quietly fostering since Wave acquired MIPS Technologies in June, explained Swift. Swift himself is a MIPS alumnus who worked at the company as a vice president of marketing and business development for four years. Wave, which styles itself as a tech startup poised to bring "AI and deep learning from the datacenter to the edge," sees MIPS as a key to advancing Wave's AI into a host of uses and applications. Included in MIPS instruction sets are extensions such as SIMD (single instruction, multiple data) and DSP. Swift promised that MIPS will bring to the open-source community "commercial-ready" instruction sets with "industrial-strength" architecture. "Chip designers will have opportunities to design their own cores based on proven and well tested instruction sets for any purposes," said Swift.' -- source: https://news.slashdot.org/story/18/12/17/1954247 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 isn’t the company that we should have handed the Web over to
by Peter Reutemann 17 Dec '18

17 Dec '18

'With Microsoft's decision to end development of its own Web rendering engine and switch to Chromium, control over the Web has functionally been ceded to Google. That's a worrying turn of events, given the company's past behavior. Chrome itself has about 72 percent of the desktop-browser market share. Edge has about 4 percent. Opera, based on Chromium, has another 2 percent. The abandoned, no-longer-updated Internet Explorer has 5 percent, and Safari—only available on macOS—about 5 percent. When Microsoft's transition is complete, we're looking at a world where Chrome and Chrome-derivatives take about 80 percent of the market, with only Firefox, at 9 percent, actively maintained and available cross-platform. The mobile story has stronger representation from Safari, thanks to the iPhone, but overall tells a similar story. Chrome has 53 percent directly, plus another 6 percent from Samsung Internet, another 5 percent from Opera, and another 2 percent from Android browser. Safari has about 22 percent, with the Chinese UC Browser sitting at about 9 percent. That's two-thirds of the mobile market going to Chrome and Chrome derivatives. In terms of raw percentages, Google won't have quite as big a lock on the browser space as Microsoft did with Internet Explorer—Internet Explorer 6 peaked at around 80 percent, and all versions of Internet Explorer together may have reached as high as 95 percent. But Google's reach is, in practice, much greater: not only is the Web a substantially more important place today than it was in the early 2000s, but also there's a whole new mobile Web that operates in addition to the desktop Web.' -- source: https://arstechnica.com/gadgets/2018/12/the-web-now-belongs-to-google-and-t… 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 Alternative Software Licenses Represent Open Source's 'Midlife Crisis'?
by Peter Reutemann 16 Dec '18

16 Dec '18

'"it is clear to me that open source -- now several decades old and fully adult -- is going through its own midlife crisis," writes Joyent CTO Bryan Cantrill. [O]pen source business models are really tough, selling software-as-a-service is one of the most natural of them, the cloud service providers are really good at it -- and their commercial appetites seem boundless. And, like a new cherry red two-seater sports car next to a minivan in a suburban driveway, some open source companies are dealing with this crisis exceptionally poorly: they are trying to restrict the way that their open source software can be used. These companies want it both ways: they want the advantages of open source -- the community, the positivity, the energy, the adoption, the downloads -- but they also want to enjoy the fruits of proprietary software companies in software lock-in and its concomitant monopolistic rents. If this were entirely transparent (that is, if some bits were merely being made explicitly proprietary), it would be fine: we could accept these companies as essentially proprietary software companies, albeit with an open source loss-leader. But instead, these companies are trying to license their way into this self-contradictory world: continuing to claim to be entirely open source, but perverting the license under which portions of that source are available. Most gallingly, they are doing this by hijacking open source nomenclature. Of these, the laughably named commons clause is the worst offender (it is plainly designed to be confused with the purely virtuous creative commons), but others...are little better... "[T]heir business model isn't their community's problem, and they should please stop trying to make it one," Cantrill writes, adding letter that "As we collectively internalize that open source is not a business model on its own, we will likely see fewer VC-funded open source companies (though I'm honestly not sure that that's a bad thing)..." He also points out that "Even though the VC that led the last round wants to puke into a trashcan whenever they hear it, business models like 'support', 'services' and 'training' are entirely viable!" Jay Kreps, Co-founder of @confluentinc, has posted a rebuttal on Medium. "How do you describe a license that lets you run, modify, fork, and redistribute the code and do virtually anything other than offer a competing SaaS offering of the product? I think Bryan's sentiment may be that it should be called the Evil Proprietary Corruption of Open Source License or something like that, but, well, we disagree."' -- source: https://news.slashdot.org/story/18/12/15/2221232 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 Last Independent Mobile OS
by Peter Reutemann 16 Dec '18

16 Dec '18

'The year was 2010 and the future of mobile computing was looking bright. The iPhone was barely three years old, Google's Android had yet to swallow the smartphone market whole, and half a dozen alternative mobile operating systems -- many of which were devoutly open source -- were preparing for launch. Eight years on, you probably haven't even heard of most of these alternative mobile operating systems, much less use them. Today, Android and iOS dominate the global smartphone market and account for 99.9 percent of mobile operating systems. Even Microsoft and Blackberry, longtime players in the mobile space with massive revenue streams, have all but left the space. Then there's Jolla, the small Finnish tech company behind Sailfish OS, which it bills as the "last independent alternative mobile operating system." Jolla has had to walk itself back from the edge of destruction several times over the course of its seven year existence, and each time it has emerged battered, but more determined than ever to carve out a spot in the world for a truly independent, open source mobile operating system. Jolla's Sailfish OS rose from the ashes of Nokia and Intel's ill-fated collaboration, MeeGo. The MeeGo project launched in 2010 in an attempt to merge Intel's Linux-based Moblin OS and Nokia's Maemo software platform into a single open-source mobile operating system that could take on Google. By 2011, Android had already surpassed Nokia in the smartphone market, a fact that wasn't lost on Nokia's CEO Stephen Elop, who in a memo described the company as standing on a "burning platform." Nokia only ever released one phone running MeeGo: the Nokia N9, which ended up being well received despite its limited release. But it was too little, too late. By 2011, Nokia was bleeding talent and it was clear that MeeGo wasn't going to keep the company competitive in the rapidly changing smartphone market. In a last-ditch effort, Nokia struck a partnership with Microsoft to provide the hardware for its next generation of Windows Phones, abandoning MeeGo entirely. The same couldn't be said for those developers who had worked on MeeGo and, before that, an open source mobile OS called Mer, based on Intel's Maemo system. In October 2011, three developers that had worked on Mer sent a message on a mailing list calling for the creation of a "MeeGo 2.0." At the same time, developer Sami Pienimaki and two others left Nokia to found their own company, which would use this new version of MeeGo as the basis for an open source mobile OS. And thus, Sailfish was born. In a cheeky homage to the "burning platform" memo, Pienimaki and his fellow defectors decided to name their company Jolla, a Finnish word connoting a small boat or life raft. Jolla has since turned to Russia and China, both of which were hungry for a secure alternative to Google-based systems. In late 2016, Sailfish OS achieved domestic certification in Russia for government and corporate us. Around the same time, Sailfish was also making moves in China. In early 2017, the Sailfish China Consortium gained the exclusive rights and license to develop a Chinese OS based on Sailfish.' -- source: https://hardware.slashdot.org/story/18/12/16/0758215 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/

Tesla Model 3 Modded To Run Ubuntu
by Peter Reutemann 16 Dec '18

'CleanTechnica is reporting that someone hacked the infotainment system of a Tesla Model 3 and got root access and installed Linux distribution Ubuntu. Redditor trsohmers is able to show an Ubuntu command shell running alongside the Tesla OS. Since Tesla supports a browser that allows you to visit any site, could this be leveraged into remote hacks? It could also mean that if Tesla sells a long-range version of the Model 3, but limits it via software, people might try to remove the block. One could potentially get a 15-day trial of full self-driving for free and extend that 15-day window forever. At least he had some guts messing with $50,000 hardware that phones home all the time.

In a Test, 3D Model of a Head Was Able To Fool Facial Recognition System of Several Popular Android Smartphones
by Peter Reutemann 13 Dec '18

13 Dec '18

'Forbes magazine tested four of the most popular handsets running Google's operating systems and Apple's iPhone to see how easy it'd be to break into them with a 3D-printed head. All of the Android handsets opened with the fake. Apple's phone, however, was impenetrable. From the report: For our tests, we used my own real-life head to register for facial recognition across five phones. An iPhone X and four Android devices: an LG G7 Linq, a Samsung S9, a Samsung Note 8 and a OnePlus 6. I then held up my fake head to the devices to see if the device would unlock. For all four Android phones, the spoof face was able to open the phone, though with differing degrees of ease. The iPhone X was the only one to never be fooled. There were some disparities between the Android devices' security against the hack. For instance, when first turning on a brand new G7 Linq, LG actually warns the user against turning facial recognition on at all. No surprise then that, on initial testing, the 3D-printed head opened it straightaway. [...] The OnePlus 6 came with neither the warnings of the other Android phones nor the choice of slower but more secure recognition.' -- source: https://apple.slashdot.org/story/18/12/13/1438218 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/

Unfortunately, the old adage “if you’re not paying for the product, then you are the product” applies yet again. Notwithstanding a personal reply from a high-up Facebook exec at the end of the above article, don’t expect these algorithms to be “smart enough” to do anything more than maximize advertising revenue. Anything more ends up counting as “unnecessary expenditure”.

Could NZ Get Its Own “Assistance and Access” Law?
by Lawrence D'Oliveiro 11 Dec '18

11 Dec '18

The ever-perceptive Juha Saarinen gives his commentary <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=121750…> on the law recently passed in Australia to compel access to decrypted forms of encrypted communications. Thanks to the new law requiring them to quietly add that backdoor that mustn't be called a backdoor into their code, Aussie developers can no longer be trusted by their international peers. You can't say no when government agencies issue a notice, saying absolutely do not tell your employer about it or you'll cop a hefty punishment. But the law is not supposed to achieve this by introducing “systemic weaknesses” into the encryption. Can you use that as a defence against having to weaken the encryption? Not a chance. The not-so-fine irony is that the Aussie Government is doing the same thing it alleges the Chinese spies would force Huawei to do, and which was considered dangerous enough to ban the telco equipment vendor from national communications networks. This gets pointed out repeatedly about similar discussions in the US, UK etc. But there seems to be a mentality among politicians, law enforcement, spies etc that “we’re the good guys, they’re the bad guys, therefore what we do cannot be classed in the same league as what they do”. Forgetting that what makes us good is that we don’t act like bad guys. And the kicker: The risk now is that other Five-Eyes countries, including New Zealand, follow Australia into making the same monumental mistake. What are the odds?

New Firefox Suggests Ways To Get More Out of the Web
by Peter Reutemann 11 Dec '18

11 Dec '18

'Starting Tuesday, Firefox will nudge you to try out options designed to make the web more interesting, more useful or more productive. From a report: Mozilla's new Firefox 64 keeps an eye on what you're up to and prompts you to try extensions and features that could help you with that activity, the browser maker said. For example, if you open the same tab lots of times, it could suggest you pin it to your tab strip for easier future access. Other suggestions include installing the Facebook Container extension to curtail the social network's snooping, a Google Translate extension to tap into Google's service, and the Enhancer for YouTube extension to do things like block ads and control playback on Google's video site. The feature could help you customize Firefox more to your liking -- something that could help you stick with the browser in the face of Google Chrome's dominance. And that, in turn, could help Mozilla pursue its push toward a privacy-respecting web that's not just effectively controlled by Chrome.' -- source: https://news.slashdot.org/story/18/12/11/1756217 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 Trojan Steals Money From PayPal Accounts Even With 2FA On
by Peter Reutemann 11 Dec '18

After being launched, the malicious app terminates without offering any functionality and hides its icon.

Microsoft Fixes Notepad

Windows Notepad has never been able to handle any newline convention other than the old DOS/Windows/CP/M one (CR-LF).

Presentations using the Waikato Uni video projector - Console windows font size.
by Ian Stewart 11 Dec '18

11 Dec '18

Hi, This is mostly a memo to myself as I have twice been caught out with Linux consoles being displayed with too small a font on the Uni video projector. However the following may also be useful to other presenters in the future. Most wlug presentations are done with a Linux laptop or PC running in a GUI Environment that is connected to the video projector. If you open a GUI console terminal window or web-browser window and the video projector display is difficult to read, then you can increase the size with the keystroke sequence Control + Shift + Plus, or decrease the size with Control + Minus. Linux also has 6 x console windows available. The keystroke sequence Ctrl + Alt + F1 opens tty1 console, through to Ctrl + Alt + F6 opening tty6 console. Note that Ctrl + Alt + F7 returns you to the laptops GUI environment. As your laptop/pc is likely to auto-size to the resolution of the video projector, then I think your laptop will opt to displaying the 1080p resolution of 1920 x 1080 pixels. By default your Linux consoles are likely to be configured to display a "Fixed" font of "8x16". When you display your console window with the video projector then one page of the display will be about 60 lines of text with 200 characters across the page. This is almost impossible to read on the projector screen. One way to overcome this problem this is to edit... /etc/default/console-setup You will see... FONTFACE="Fixed" FONTSIZE="8x16" At the bottom of the file add something like... # For Waikato University Video Projector # Choices of Fontsize with Terminus font: # 6x12, 8x14, 8x16, 10x20, 11x22, 12x24, 14x28, 16x32 FONTFACE="Terminus" FONTSIZE="14x28" ...save the changes to the console-setup file and execute... $ setupcon The console displayed should now be about 35 rows by 80 character cells, and should allow everyone to read what is displayed. cheers, Ian. PS: Another approach to making these changes is... $ dpkg-reconfigure console-setup ...this will step through 4 x graphical input screens. From these screens select "Terminus" as the Font and the "14x28" as the Font size. To restore to the original settings run dpkg-reconfigure console-setup again and select "Fixed" and "8x16".

Malicious Sites Abuse 11-Year-Old Firefox Bug That Mozilla Failed To Fix
by Peter Reutemann 11 Dec '18

11 Dec '18

'Malware authors, ad farmers, and scammers are abusing a Firefox bug to trap users on malicious sites. From a report: This wouldn't be a big deal, as the web is fraught with this kind of malicious sites, but these websites aren't abusing some new never-before-seen trick, but a Firefox bug that Mozilla engineers appear to have failed to fix in the 11 years ever since it was first reported back in April 2007. The bug narrows down to a malicious website embedding an iframe inside their source code. The iframe makes an HTTP authentication request on another domain. [...] For the past few years, malware authors, ad farmers, and scammers have been abusing this bug to lure users on sites where they show all sorts of nasties, such as tech support scams, ad farms that reload the page with new ads in a loop, pages that push users to buy fake gift cards, or sites that offer malware-laced software updates. Whenever users try to leave, the owners of these shady sites trigger the authentification modal in a loop.' -- source: https://news.slashdot.org/story/18/12/10/0220258 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/

Faxes To Be Banned At The NHS
by Lawrence D'Oliveiro 10 Dec '18

10 Dec '18

The UK’s National Health Service is being forced to phase out its heavy reliance on fax machines <https://www.theregister.co.uk/2018/12/10/hancock_fax_ban_nhs/> and resort to more, um, “digital” alternatives like e-mail instead: However, it's worth noting that just last week, up to 1.2 million staffers were locked out of their NHSmail accounts after Accenture reportedly botched a data centre upgrade. [Helen Stokes-Lampard, chair of the Royal College of General Practitioners] raised similar concerns about the resilience of the IT systems the NHS is racing to introduce. "What's shocking is how often digital innovations fall over," she said. "It doesn't mean we shouldn’t do it, but what it does mean is we have to be realistic about with the time scales for this."

National Oracle System Is A Write-Off

Looks like the nationwide attempt to streamline and update the IT systems of all the DHBs is now going to be written off <https://www.theregister.co.uk/2018/12/10/national_oracle_solution_write_dow…>. It hasn’t officially been abandoned, mind you, but because it’s been “on hold” for so long, the DHBs are now obliged to start recording “impairments” in their accounts over their investment in the system. By the way, the Waikato DHB was one of the four that managed a rollout of the system so far. Not sure whether that stays in place or gets rolled back...

How to Auto Backup Files to USB Media When Connected
by Peter Reutemann 10 Dec '18

10 Dec '18

'A backup is the last defense against data loss, offering a means to restore original data. You can use either a removable media such as an external hard drive or USB flash disk or a shared network folder, or a remote host to back up your data. It’s very easy (and equally essential) to automatically backup your important files without you having to remember to do so. In this article, we will learn how to auto backup data to a removable media after connecting it to your Linux machine. We will test with an external disk. This is a basic guide to get you started with using udev for real-life solutions.' -- source: https://www.tecmint.com/auto-backup-files-to-usb-media-in-linux/ 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.org's DNS Got Hijacked
by Peter Reutemann 09 Dec '18

09 Dec '18

'Linux.org reports: Wednesday afternoon around 5pm EST someone was able to get into the registrar account for our domain and point DNS to another server -- as well as lock us out from changing it. They pointed the domain name to a pretty rude page for most of the evening until Cloudflare stepped in and blocked the domain for us. After a lot of back and forth with our registrar, we were able to get things back under our control. I'd like to point out that our server environment was not touched so there are no worries about your data. We've gone over security protocols and are tightening things up that may have slipped through in the past. Thanks for your support! Linux.org apparently pointed to a page exclaiming "G3T 0WNED L1NUX N3RDZ", which also included a NSFW picture, some abusive language, a shout-out to recently-deceased programmer Terry Davis, and a link to an article about Linus Torvalds' controversial apology for "his hostile behavior towards others in the community." Long-time Slashdot reader Grady Martin says he also saw the page pointing to "presumably doxed info" about the creator of Linux's code of conduct, a fact confirmed by a report in the Register. "As for how it was hacked, [Linux.org owner Mike] McLagan blames the public Whois displaying his partner's email address -- presumably the hacker worked their way into the Yahoo email account listed as the admin of the site and from there requested a password change in her Network Solutions account to gain access to the domain."' -- source: https://it.slashdot.org/story/18/12/08/0355227 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/

Running Linux Mint 19.1
by tom butz 07 Dec '18

07 Dec '18

Linux Mint 19.1 works well using my laptop (Toshiba Z930 6 GB RAM) and a USB3 connection to a 500G USB3-harddisk. I first tried a fast 10-speed 64GB SD-card, but that actually seemed to be slower - and the SD-card would have worn out in the end. For some reason Mint has got a swapFILE in the root directory - pretty hard on the SD-card. I haven't got USB3.1 (yet). 19.1 supports Bluetooth in both directions: under Mint 19, I couldn't send from Mint to my Android phone (Android 7.1) 19.1 also features snapshots. I didn't have to test them as I prefer to run Mint off my laptop (no power-cuts there). Occasionally I run it off my MacMini (8 GB of RAM, OS 10.7.5). The MacOS is too old for many things, and to avoid having to buy new Mac gear, I 'upgraded' by running Mint on it. Tom Butz.

Report: Microsoft is scrapping Edge, switching to just another Chrome clone
by Peter Reutemann 06 Dec '18

06 Dec '18

'Windows Central reports that Microsoft is planning to replace its Edge browser, which uses Microsoft's own EdgeHTML rendering engine and Chakra JavaScript engine, with a new browser built on Chromium, the open source counterpart to Google's Chrome. The new browser has the codename Anaheim. The report is short on details. The easiest thing for Microsoft to do would be to use Chromium's code wholesale—the Blink rendering engine, the V8 JavaScript engine, and the Chrome user interface with the Google Account parts omitted—to produce something that looks, works, and feels almost identical to Chrome. Alternatively, Redmond could use Blink and V8 but wrap them in Edge's user interface (or some derivative thereof), to retain its own appearance. It might even be possible to do something weird, such as use Blink with the Chakra JavaScript engine. We'll have to wait and see.' -- source: https://arstechnica.com/gadgets/2018/12/report-microsoft-is-scrapping-edge-… 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/

White House Cybersecurity Advisor Gets Hacked

In July...” Unfortunately he left out the space in “G-20. In”, turning it into “G-20.In”, which Twitter automatically formatted as a link. Someone noticed that the domain name in question was available, and promptly snapped it up and used it to post an anti-Trump message. This has made Mr Giuliani somewhat angry. He has tried to blame Twitter for the slipup, claiming the social media service “allowed someone to invade my text with a disgusting anti-President message”, as though he was not the one who created the link in the first place. Remember, this man has the job of advising the entire executive arm of the US government on keeping people’s computer usage secure. I wonder if he’s figured out how to delete a tweet yet?

Google Personalizes Search Results Even When You're Logged Out, a DuckDuckGo Study Finds
by Peter Reutemann 05 Dec '18

05 Dec '18

'According to a new study conducted by Google competitor DuckDuckGo, it does not seem possible to avoid personalization when using Google search, even by logging out of your Google account and using the private browsing "incognito" mode. From a report: DuckDuckGo conducted the study in June of this year, at the height of the US midterm election season. It did so with the ostensible goal of confirming whether Google's search results exacerbate ideological bubbles by feeding you only information you've signaled you want to consume via past behavior and the data collected about you. It's not clear whether that question can be reliably answered with these findings, and it's also obvious DuckDuckGo is a biased source with something to gain by pointing out how flawed Google's approach may be. But the study's findings are nonetheless interesting because they highlight just how much variance there are in Google search results, even when controlling for factors like location.' -- source: https://search.slashdot.org/story/18/12/04/1610237 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/

Kubernetes' First Major Security Hole Discovered

'Kubernetes has become the most popular cloud container orchestration system by far, so it was only a matter of time until its first major security hole was discovered. And the bug, CVE-2018-1002105, aka the Kubernetes privilege escalation flaw, is a doozy. It's a CVSS 9.8 critical security hole. From a report: With a specially crafted network request, any user can establish a connection through the Kubernetes application programming interface (API) server to a backend server. Once established, an attacker can send arbitrary requests over the network connection directly to that backend. Adding insult to injury, these requests are authenticated with the Kubernetes API server's Transport Layer Security (TLS) credentials. Can you say root? I knew you could. Worse still, "In default configurations, all users (authenticated and unauthenticated) are allowed to perform discovery API calls that allow this escalation." So, yes, anyone who knows about this hole can take command of your Kubernetes cluster.' -- source: https://it.slashdot.org/story/18/12/04/1958222 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/

Blockchain Study Finds 0% Success Rate and Vendors Don't Call Back When Asked For Evidence
by Peter Reutemann 04 Dec '18

04 Dec '18

'Though Blockchain has been touted as the answer to everything, a study of 43 solutions advanced in the international development sector has found exactly no evidence of success. From a report: Three practitioners including erstwhile blockchain enthusiast John Burg, a Fellow at the US Agency for International Development (USAID), looked at instances of the distributed crypto ledger being used in a wide range of situations by NGOs, contractors and agencies. But they drew a complete blank. "We found a proliferation of press releases, white papers, and persuasively written articles," Burg et al wrote. "However, we found no documentation or evidence of the results blockchain was purported to have achieved in these claims. We also did not find lessons learned or practical insights, as are available for other technologies in development." Blockchain vendors were keen to puff the merits of the technology, but when the three asked for proof of success in the field, it all went very quiet. "We fared no better when we reached out directly to several blockchain firms, via email, phone, and in person. Not one was willing to share data on program results, MERL [monitoring, evaluation, research and learning] processes, or adaptive management for potential scale-up. Despite all the hype about how blockchain will bring unheralded transparency to processes and operations in low-trust environments, the industry is itself opaque."

Is Linux Taking Over The World?
by Peter Reutemann 02 Dec '18

02 Dec '18

'"2019 just might be the Year of Linux -- the year in which Linux is fully recognized as the powerhouse it has become," writes Network World's "Unix dweeb." The fact is that most people today are using Linux without ever knowing it -- whether on their phones, online when using Google, Facebook, Twitter, GPS devices, and maybe even in their cars, or when using cloud storage for personal or business use. While the presence of Linux on all of these systems may go largely unnoticed by consumers, the role that Linux plays in this market is a sign of how critical it has become. Most IoT and embedded devices -- those small, limited functionality devices that require good security and a small footprint and fill so many niches in our technology-driven lives -- run some variety of Linux, and this isn't likely to change. Instead, we'll just be seeing more devices and a continued reliance on open source to drive them. According to the Cloud Industry Forum, for the first time, businesses are spending more on cloud than on internal infrastructure. The cloud is taking over the role that data centers used to play, and it's largely Linux that's making the transition so advantageous. Even on Microsoft's Azure, the most popular operating system is Linux. In its first Voice of the Enterprise survey, 451 Research predicted that 60 percent of nearly 1,000 IT leaders surveyed plan to run the majority of their IT off premises by 2019. That equates to a lot of IT efforts relying on Linux. Gartner states that 80 percent of internally developed software is now either cloud-enabled or cloud-native. The article also cites Linux's use in AI, data lakes, and in the Sierra supercomputer that monitors America's nuclear stockpile, concluding that "In its domination of IoT, cloud technology, supercomputing and AI, Linux is heading into 2019 with a lot of momentum." And there's even a long list of upcoming Linux conferences...' -- source: https://linux.slashdot.org/story/18/12/01/2018223 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/

Node.js Event-Stream Hack Reveals Open Source 'Developer Infrastructure' Exploit
by Peter Reutemann 02 Dec '18

02 Dec '18

'"[O]n Nov. 26 it was publicly revealed that a widely deployed open-source Node.js programming language module known as event-stream had been injected with malicious code that looked to steal cryptocurrency wallets," reports eWeek, adding "The event-stream library has over two million downloads." An anonymous reader quotes Ars Technica: The backdoor came to light [November 20th] with this report from Github user Ayrton Sparling. Officials with the NPM, the open source project manager that hosted event-stream, didn't issue an advisory until six days later.... "This compromise was not targeting module developers in general or really even developers," an NPM official told Ars in an email. "It targeted a select few developers at a company, Copay, that had a very specific development environment set up. Even then, the payload itself didn't run on those developers' computers; rather, it would be packaged into a consumer-facing app when the developers built a release. The goal was to steal Bitcoin from this application's end users...." According to the Github discussion that exposed the backdoor, the longtime event-stream developer no longer had time to provide updates. So several months ago, he accepted the help of an unknown developer. The new developer took care to keep the backdoor from being discovered. Besides being gradually implemented in stages, it also narrowly targeted only the Copay wallet app. The malicious code was also hard to spot because the flatmap-stream module was encrypted. The attack is the latest to exploit weaknesses in a widely used supply chain to target downstream end users... The supply-chain attacks show one of the weaknesses of open source code. Because of its openness and the lack of funds of many of its hobbyist developers and users, open source code can be subject to malicious modifications that often escape notice. "The time has come," concludes Ars Technica, "for maintainers and users of open source software to devise new measures to better police the millions of packages being used all around us." Sophos' security blog also asks why so many developers "immediately and blindly trusted the new maintainer," and shared a concerned comment from developer named Chris Northwood.' -- source: https://it.slashdot.org/story/18/12/01/2217231 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/

Australia Has Rushed Through Its Copyright Amendment Bill
by Lawrence D'Oliveiro 30 Nov '18

30 Nov '18

Seems like the Aussie government has disregarded <https://www.theregister.co.uk/2018/11/28/australia_to_build_a_pirateproof_f…> <https://www.techdirt.com/articles/20181127/13425541113/australian-parliamen…> most of the objections to its plan to impose more draconian copyright restrictions on Internet usage. Rightsholders will be able to get injunctions against sites whose “primary effect” (no longer just “primary purpose”) is to facilitate copyright infringement, and they will also have “adaptive injunctions”, meaning they can reinterpret an existing court order as circumstances change, instead of having to go back to court to get a new order. You’d think a statement like “The Government has zero tolerance for online piracy. It is theft...” should be an instant disqualification from making any kind of statement about copyright law...

Mass Router Hack Exposes Millions of Devices To Potent NSA Exploit
by Peter Reutemann 29 Nov '18

29 Nov '18

'More than 45,000 Internet routers have been compromised by a newly discovered campaign that's designed to open networks to attacks by EternalBlue, the potent exploit that was developed by, and then stolen from, the National Security Agency and leaked to the Internet at large, researchers say. From a report: The new attack exploits routers with vulnerable implementations of Universal Plug and Play to force connected devices to open ports 139 and 445, content delivery network Akamai said in a blog post. As a result, almost 2 million computers, phones, and other network devices connected to the routers are reachable to the Internet on those ports. While Internet scans don't reveal precisely what happens to the connected devices once they're exposed, Akamai said the ports --which are instrumental for the spread of EternalBlue and its Linux cousin EternalRed -- provide a strong hint of the attackers' intentions. The attacks are a new instance of a mass exploit the same researchers documented in April. They called it UPnProxy because it exploits Universal Plug and Play -- often abbreviated as UPnP -- to turn vulnerable routers into proxies that disguise the origins of spam, DDoSes, and botnets.' -- source: https://tech.slashdot.org/story/18/11/29/1849254 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/

Proprietary Software Subverts Security Of Your PC
by Lawrence D'Oliveiro 28 Nov '18

28 Nov '18

Audio company Sennheiser has just issued a fix <https://arstechnica.com/information-technology/2018/11/sennheiser-discloses…> for a really nasty vulnerability where their software for Windows and Mac would install a special fake browser certificate that the machine would continue to trust thereafter, even after the software was removed. Unfortunately, because the installation also included the private key for that certificate (which is never supposed to be distributed), it could then be exploited by arbitrary third parties to trick such machines into trusting random sites.

Half of all Phishing Sites Now Have the Padlock
by Peter Reutemann 27 Nov '18

27 Nov '18

'You may have heard you should look for the padlock symbol at the top of a website before entering your password or credit card information into an online form. It's well-meaning advice, but new data shows it isn't enough to keep your sensitive information secure. From a report: Recent data from anti-phishing company PhishLabs shows that 49 percent of all phishing sites in the third quarter of 2018 bore the padlock security icon next to the phishing site domain name as displayed in a browser address bar. That's up from 25 percent just one year ago, and from 35 percent in the second quarter of 2018. This alarming shift is notable because a majority of Internet users have taken the age-old "look for the lock" advice to heart, and still associate the lock icon with legitimate sites. A PhishLabs survey conducted last year found more than 80% of respondents believed the green lock indicated a website was either legitimate and/or safe. In reality, the https:// part of the address (also called "Secure Sockets Layer" or SSL) merely signifies the data being transmitted back and forth between your browser and the site is encrypted and can't be read by third parties. The presence of the padlock does not mean the site is legitimate, nor is it any proof the site has been security-hardened against intrusion from hackers.' -- source: https://it.slashdot.org/story/18/11/27/1521240 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/

Two Linux Kernels Revert Performance-Killing Spectre Patches
by Peter Reutemann 25 Nov '18

25 Nov '18

'Friday Greg Kroah-Hartman released stable point releases of Linux kernel 4.19.4, as well as 4.14.83 and 4.9.139. While they were basic maintenance updates, the 4.19.4 and 4.14.83 releases are significant because they also reverted the performance-killing Spectre patches (involving "Single Thread Indirect Branch Predictors", or STIBP) that had been back-ported from Linux 4.20, according to Phoronix: There is improved STIBP code on the way for Linux 4.20 that by default just applies STIBP to SECCOMP threads and processes requesting it via prctl() but otherwise is off by default (that behavior can also be changed via kernel parameters). Once that code is ready to go for Linux 4.20, we may see it then back-ported to these stable trees. Aside from reverting STIBP, these point releases just have various fixes in them as noted for 4.19.4, 4.14.83, and 4.9.139. Last Sunday Linus Torvalds complained that the performance impact of the STIPB code "was clearly way more expensive than people were told," according to ZDNet: "When performance goes down by 50 percent on some loads, people need to start asking themselves whether it was worth it. It's apparently better to just disable SMT entirely, which is what security-conscious people do anyway," wrote Torvalds. "So why do that STIBP slow-down by default when the people who *really* care already disabled SMT?"' -- source: https://linux.slashdot.org/story/18/11/24/2320228 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/

Alphabet's Cybersecurity Group Touts Its New Open Source Private VPN
by Peter Reutemann 25 Nov '18

25 Nov '18

'Alphabet's cybersecurity division Jigsaw has designed a new open source private VPN aimed at journalists and the people sending them data. "Their work makes them more vulnerable to attack," said Santiago Andrigo, Jigsaw's product manager. "It can get really scary when they're outed and you're passing over information." Unscrupulous VPN providers can steal your identity, peek in on your data, inject their own ads on non-secure pages, or analyze your browsing habits and sell that information to advertisers, says one Jigsaw official. And you can't know for sure whether you can trust them, no matter what they say in the app store. "Journalists should be aware that their online activities might be subject to surveillance either by government agencies, their internet service providers or a hacker with malicious intent," said Laura Tich, technical evangelist for Code for Africa, a resource for African journalists. "As surveillance becomes ubiquitous in today's world, journalists face an increasing challenge in establishing secure communication in the digital space." The new private VPN, dubbed "Outline", is specifically designed to be resistant to censorship — because it's harder to detect as a VPN (and therefore is less likely to be blocked). Outline uses an encrypted socks5 proxy that looks like normal internet traffic. Once the user chooses a server location, Outline spins up a DigitalOcean server on Ubuntu, installs Docker, and imports an image of the actual server. It's been named Outline because in places where internet use may be restricted — it gives you a line out.' -- source: https://yro.slashdot.org/story/18/11/25/0117226 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 Gmail Bug Allows Sending Messages Anonymously
by Peter Reutemann 25 Nov '18

25 Nov '18

'Earlier this week software developer Tim Cotten discovered a serious glitch in Gmail. An anonymous reader quotes BleepingComputer: Tampering with the 'From:' header by replacing some text with an <object>, <script> or <img> tag causes the interface to show a blank space instead of the sender's address.... Opening the email does not help, either, as the sender's address continues to remain hidden and shows no info even when hovering on it, an action that typically reveals the details.... Trying to reply to the message is also of no help. Cotten attempted this thinking that Gmail would read the original email headers and determine the destination. "Wrong again! Gmail is at a complete loss at what to do!" Cotten writes in a blog post that details his new finding.... Using the Show Original option, which allows users with more experience to trace an email, the desired detail is still unavailable in the user-friendly view. Looking at the raw info, however, shows the source address buried at the end of the <img> tag Cotten used in his experiment. He didn't even have to spell correctly the data type to trigger the bug. Unfortunately, it is highly unlikely that the average Gmail user will be able to navigate to this area and determine who the apparently anonymous message is coming from. Due to this, for these users the risk of phishing is high. Cotten's bug report "relies on his previous discovery that proved how a malformed 'From:' header allows placing an arbitrary email address in the sender field," the article points out, also noting a third recently-reported Gmail bug that "allows fraudsters to create a 'mailto:' link that populates the destination field in the app with whatever address they want; the latter was reported about 19 months ago to Google and is still present in the Gmail app for Android." "According to the developer, one solution Google could implement to avoid forging the From field is to properly check the email headers and deny communication with an anomalous structure in the sender or recipient fields. Another method proposed by Cotten is Joran Greef's project Ronomon, which can trigger errors when email specifications are not followed." Threatpost reported Tuesday that Google "did not respond to a request for comment."' -- source: https://it.slashdot.org/story/18/11/25/1731238 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/

Potentially disastrous Rowhammer bitflips can bypass ECC protections
by Peter Reutemann 22 Nov '18

22 Nov '18

'In early 2015, researchers unveiled Rowhammer, a cutting-edge hack that exploits unfixable physical weaknesses in the silicon of certain types of memory chips to transform data they stored. In the 42 months that have passed since then, an enhancement known as error-correcting code (or ECC) available in higher-end chips was believed to be an absolute defense against potentially disastrous bitflips that changed 0s to 1s and vice versa.

From <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=121638…>: ... global smartphone sales saw their first year-on-year fall in history at the end of 2017. Apple seemed unaffected at the time, but its latest quarterly results now show falls in unit sales, as a result of which it will stop reporting them in future. >From beginnings that we might date to around the mid-1970s, PC sales (and development) went on an uninterrupted upward curve right through the 1990s, only starting to stutter around about the 2000s. The smartphone revolution, even if it includes the Symbian era and not just Android and Apple, has not lasted quite as long. So what new information-processing technology will ignite the mass market next? If any?

Microsoft Disputing Its NZ Tax Payments
by Lawrence D'Oliveiro 19 Nov '18

19 Nov '18

The IRD is demanding that Microsoft NZ pay more tax <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=121627…>. This is over the whole notorious business of “transfer pricing”, where sales by multinational corporations are recorded in jurisdictions where they attract less tax, rather than where the customers are located. Looks like there have already been some changes to this, though obviously the dispute would be over whether those changes are enough: From February 2018, the local unit's accounts were extended to include the distribution of computer software and hardware, having previously covered marketing. The change effectively means local product sales are being captured. Concomitant with this: The changes to Microsoft's revenue recognition also seem to route GST through the local unit, with GST payments of $8.1 million in the year ended June 30, compared to just $13,441 a year earlier. Man, that’s quite a jump. All of Microsoft’s NZ customers incurring just $13,441 in GST over an entire year ...

Mark Shuttleworth Reveals Ubuntu 18.04 Will Get a 10-Year Support Lifespan
by Peter Reutemann 18 Nov '18

18 Nov '18

'At the OpenStack Summit in Berlin last week, Ubuntu Linux founder Mark Shuttleworth said in a keynote that Ubuntu 18.04 Long Term Support (LTS) support lifespan would be extended from five years to 10 years. "I'm delighted to announce that Ubuntu 18.04 will be supported for a full 10 years," said Shuttleworth, "In part because of the very long time horizons in some of industries like financial services and telecommunications but also from IoT where manufacturing lines for example are being deployed that will be in production for at least a decade." ZDNet reports: Ubuntu 18.04 released in April 2018. While the Ubuntu desktop gets most of the ink, most of Canonical's dollars comes from server and cloud customers. It's for these corporate users Canonical first extended Ubuntu 12.04 security support, then Ubuntu 14.04's support, and now, preemptively, Ubuntu 18.04. In an interview after the keynote, Shuttleworth said Ubuntu 16.04, which is scheduled to reach its end of life in April 2021, will also be given a longer support life span. When it comes to OpenStack, Shuttleworth promised again to support versions of OpenStack dating back to 2014's IceHouse. Shuttleworth said, "What matters isn't day two, what matters is day 1,500." He also doubled-down on Canonical's promise to easily enable OpenStack customers to migrate from one version of OpenStack to another. Generally speaking, upgrading from one version of OpenStack is like a root canal: Long and painful but necessary. With Canonical OpenStack, you can step up all the way from the oldest supported version to the newest one with no more than a second of downtime.

Mozilla's 'Privacy Not Included' Gift Report Highlights Security Concerns
by Peter Reutemann 15 Nov '18

15 Nov '18

'Mozilla has released its second annual "Privacy Not Included" guide that rates 70 products to help give you an idea as to how secure or insecure they are. "We want to provide people information about how to make informed decisions when shopping for gifts that are connected to the internet," says Ashley Boyd, vice president of advocacy at Mozilla. "These products are becoming really popular. And in some cases, it's easy to forget that they're even connected to the internet." Wired reports: Among the important signifiers of a trustworthy stocking stuffer, according to Mozilla's rubric: the use of encryption, pushing automatic software security updates, strong password hygiene, a way to deal with vulnerabilities should they arise, and a privacy policy that doesn't take a PhD to parse. The most surprising result of Mozilla's testing may be how many products actually earned its seal of approval. Thirty-three of the 70 items in the "Privacy Not Included" guide passed muster; fans of the Nintendo Switch, Google Home, and Harry Potter Kano Coding Kit can sleep a little easier. On the other end of the scale, Mozilla highlighted seven products that may not hit the mark -- yes, including the sous vide wand, the Anova Precision Cooker. Also scoring low marks in Mozilla's accounting: the DJI Spark Selfie Drone (no encryption, does not require users to change the default password), the Parrot Bebop 2 drone (no encryption, complex privacy policy), and unsurprisingly, at least one baby monitor. The remaining 30 items on the list all exist somewhere in the murky middle, usually because Mozilla was unable to confirm at least one attribute. Which may be the real takeaway from the report: Typically, you have no reasonable way to find out if a given internet-connected device is secure. "If you can't tell, that says that there's a problem of communication between manufacturers and consumers," says Boyd. "We would love for makers of these products to be more clear and more transparent about what they're doing and not doing. That's a big place we think change is needed."

A New Raspberry Pi 3 Model A+ Has Arrived With Bluetooth 4.2 and Dual-Band Wi-Fi For $25
by Peter Reutemann 15 Nov '18

15 Nov '18

'Raspberry Pi has introduced a new version of one of its most popular models just in time to stuff your stocking: the Model A+. And this time around, it's even more attractive. From a report: The Raspberry Pi 3 Model A+ costs $25, $5 more than the previous generation, but has a lot more going for it. Just like the top-of-the-line Model B+, the new Model A+ has a 1.4GHz 64-bit quad-core processor, and you'll also get dual-band Wi-Fi (2.4GHz + 5 GHz), a feature that was missing from the previous A+. And you'll have to use it, since the A+ doesn't have an Ethernet port. It does, however, have Bluetooth 4.2 on board. For $10 less than the $35 Model B+, you'll also only get a single USB port (versus four on the B+) as well as 512MB of RAM (versus 1GB on the B+). But otherwise, the devices are identical, with a full-size HDMI port, CSI camera port, DSI display port, stereo output and composite video port, and a micro SD port. The Raspberry Pi 3 Model A+ isn't the cheapest Pi model available -- the Zero costs $5 and the Zero W costs just $10 -- but it rounds out the options nicely. The new model is available now through Raspberry Pi retailers.' -- source: https://hardware.slashdot.org/story/18/11/15/1846205 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/

ProtonVPN Passes 1 Million Users and Launches on iOS
by Peter Reutemann 14 Nov '18

14 Nov '18

'Encrypted email service provider ProtonMail has launched its standalone VPN app for iOS devices. From a report: The announcement comes more than a year after ProtonVPN launched globally for desktop users and 10 months after it landed on Android, so the iOS launch has been a long time coming. There is, of course, no shortage of VPN apps out there already, but ProtonMail has built a solid reputation in the encrypted communications realm since it was founded out of CERN in 2013. Following the launch of its privacy-focused email service nearly three years ago, the company subsequently added two-factor authentication (2FA), Tor support, an encrypted contacts manager, and of course a VPN service. ProtonMail offers various pricing tiers for ProtonVPN, ranging from free to $24 per month. Those who choose not to pay can access three countries' servers, with access on one device, but will have slower speeds, while the top $24/month tier offers access on 10 devices with server access in all available countries. In related news, ProtonMail said that ProtonVPN now has 1 million users globally.' -- source: https://yro.slashdot.org/story/18/11/14/1646222 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 Discover Seven New Meltdown and Spectre Attacks

'A team of nine academics has revealed today seven new CPU attacks. The seven impact AMD, ARM, and Intel CPUs to various degrees.

Researchers say they've discovered the seven new CPU attacks while performing "a sound and extensible systematization of transient execution attacks" -- a catch-all term the research team used to describe attacks on the various internal mechanisms that a CPU uses to process data, such as the speculative execution process, the CPU's internal caches, and other internal execution stages. The research team says they've successfully demonstrated all seven attacks with proof-of-concept code. Experiments to confirm six other Meltdown-attacks did not succeed, according to a graph published by researchers.' -- source: https://it.slashdot.org/story/18/11/14/181225 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/

USB Hardware Firewall
by Lawrence D'Oliveiro 14 Nov '18

14 Nov '18

You may know that it is possible for USB devices to be created that do malicious things to your PC by committing deceptions right at the USB protocol level. This kind of thing cannot be defeated by antivirus software or erased by, for example, reformatting a USB stick. For example, a device that is labelled as a USB storage stick could actually identify to the PC as two devices, one the actual storage device and the other a keyboard, that feeds malicious keystrokes at carefully-chosen times. Alternatively, it can detect when the PC is booting, and activate a separate partition containing a virus, which is otherwise invisible to antivirus software, at only that point. More details about such possibilities are available here <https://opensource.srlabs.de/projects/badusb>. Here <https://github.com/robertfisk/USG/wiki> is an interesting project to create a hardware device that will act as a “firewall” for untrusted USB devices, to prevent malicious protocol exchanges from occurring between them and your PC. If you don’t want to build your own, there’s a link in the readme to buy NZ-made ones.

Seems some Microsoft support staff have confirmed that there is a “temporary issue” with the licence servers, which may take 1-2 days to fix.

WLinux, the First Paid-for Linux Distro for Windows 10, Goes On Sale on Microsoft Store
by Peter Reutemann 07 Nov '18

07 Nov '18

'WLinux is a $20 open-source, Debian-based distribution, designed to run on Windows 10's Windows Subsystem for Linux (WSL). The WSL allows Windows 10 to run various GNU/Linux distros inside Windows as Microsoft Store apps, providing access to Ubuntu, openSUSE, Debian, Fedora, Kali Linux, and others. The WSL has disadvantages over a running a dedicated GNU/Linux system. For example, there's no official support for desktop environments or graphical applications, and I/O performance bottlenecks, but it is being improved over time. The developers of WLinux describe it as a "fast Linux terminal environment for developers", saying it is the first distribution to be "pre-configured and optimized to run specifically on Windows Subsystem for Linux". Announcing WLinux's availability, Microsoft program manager Tara Raj, called out the wlinux-setup tool, "which allows users to easily set up common developer toolchains, and removes unsupported features like systemd."' -- source: https://linux.slashdot.org/story/18/11/07/1510223 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 New, Polite Linus Torvalds Points Out Bad Kernel Code
by Peter Reutemann 06 Nov '18

06 Nov '18

'Linus Torvalds "has shown already for the new Linux 4.20~5.0 cycle he isn't relaxing his standards but is communicating better when it comes to bringing up coding," reports Phoronix, adding "So far it looks like Linus' brief retreat is paying off with still addressing code quality issues -- and not blatantly accepting new code into the kernel as some feared -- but in doing so in a professional manner compared to his past manner of exclaiming himself over capitalized sentences and profanity that at time put him at odds with some in the Linux kernel community." AmiMoJo quotes their report: Last Saturday he took issue with the HID pull request and its introduction of the BigBen game controller driver that was introduced: the developer enabled this new driver by default. Linus Torvalds has always frowned upon random new drivers being enabled by default in the kernel configuration driver. [H]e still voiced his opinion over this driver's default "Y" build configuration, but did so in a more professional manner than he has done in the past: We do *not* enable new random drivers by default. And we most *definitely* don't do it when they are odd-ball ones that most people have never heard of. Yet the new "BigBen Interactive" driver that was added this merge window did exactly that. Just don't do it. Yes, yes, every developer always thinks that _their_ driver is so special and so magically important that it should be enabled by default. But no. When we have thousands of drivers, we don't randomly pick one new driver to be enabled by default just because some developer thinks it is special. It's not.... Please don't do things like this. Phoronix also describes another "kernel oops" testing Torvalds' patience, in which Linus responded tactfully that "What makes me *very* unhappy about this is that if I'm right, I think it means that code was literally not tested at all by anybody who didn't have one of the entries in that list."' -- source: https://linux.slashdot.org/story/18/11/03/1833213 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/

Explicating Neural Networks
by Lawrence D'Oliveiro 06 Nov '18

06 Nov '18

The usual problem with neural nets is, once you have trained them, you have no actual idea why they come to the decisions that they do. One classic example was a net that was being trained to distinguish between pictures of huskies and wolves, where it turned out it was actually assigning the highest weight to the area of snow in the background of the pictures. Enter LIME, which is a Python-based toolkit that tries to analyze the trained net to show you how each part of the dataset is being interpreted <https://www.theregister.co.uk/2018/11/05/hands_on_with_lime/>. The article shows example pictures where areas are colour-coded green or red to indicate whether they make a positive or negative contribution to a particular classification decision. This way, you can spot if any parts that should be ignored are being given an anomalously high weight. Or vice versa.

Microsoft Microsoft Working on Porting Sysinternals To Linux
by Peter Reutemann 05 Nov '18

05 Nov '18

'A Microsoft exec has confirmed yesterday that the company's engineers are working on porting the highly popular Sysinternals software package to Linux. Microsoft engineers have already ported the ProcDump utility and are currently working on porting ProcMon as well. More tools to follow. Microsoft's decision to port this highly popular debugging utility to Linux comes after two months ago, in September, Scott Guthrie, Microsoft's executive vice president of the cloud and enterprise group, revealed that "sometimes slightly over half of Azure VMs are Linux." With Linux's growing adoption as the preferred OS for running Azure VMs, it's only natural that Azure engineers are now looking into porting their favorite debugging utilities to Linux, for both themselves but also for the company's customers.' -- source: https://linux.slashdot.org/story/18/11/05/157226 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/

Flaws in Self-Encrypting SSDs Let Attackers Bypass Disk Encryption
by Peter Reutemann 05 Nov '18

05 Nov '18

'Researchers have found flaws that can be exploited to bypass hardware encryption in well known and popular SSD drives. Master passwords and faulty standards implementations allow attackers access to encrypted data without needing to know the user-chosen password. SSDs from Micron (Crucial) and Samsung are affected. These are SSDs that support hardware-level encryption via a local built-in chip, separate from the main CPU. Some of these devices have a factory-set master password that bypasses the user-set password, while other SSDs store the encryption key on the hard drive, from where it can be retrieved. The issue is worse on Windows, where BitLocker defers software-level encryption to hardware encryption-capable SSDs, meaning user data is vulnerable to attacks without the user's knowledge. More in the research paper.' -- source: https://it.slashdot.org/story/18/11/05/213255 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/

Old School 'Sniffing' Attacks Can Still Reveal Your Browsing History
by Peter Reutemann 04 Nov '18

04 Nov '18

'Most modern browsers -- such as Chrome, Firefox, and Edge, and even browsers such as FuzzyFox and DeterFox (different, security-focused versions of Firefox) -- have vulnerabilities that allow hosts of malicious websites to extract hundreds to thousands of URLs in a user's web history, per new research from the University of California San Diego. What's worse, the vulnerabilities are built into the way they structure links, meaning that major structural changes will have to take place in these browsers in order to protect user privacy. The only browser that was immune to the attacks was Tor Browser, as the browser does not keep track of a user's internet history. The vulnerabilities have to do with why, for instance, unclicked links appear blue while visited links appear violet: there's a different set of rules and style that apply to links depending on whether they've been visited or not. However, a bad actor building a web page can manipulate this faster loading time for visited links by "sniffing," or inferting your browsing history. In essence, sniffing is finding and exploiting proxies that reveal your web history. As outlined in the UC San Diego report, this sniffing could happen in a couple of ways: they could force the browser to reload multiple complex images or image transformations that differ based on whether you've visited a link or not, which would create drastic differences in the loading time for each. With this strategy, actors can test 60 sensitive URLs per second. Bad actors could exploit a "bytecode cache," which speeds up the loading time for revisiting a link that you've already visited. "By embedding a special script in a web page, the actor can test how long it takes for a web page to load and infer whether you've visited it or not," reports Motherboard. "Actors can probe 3,000 URLs per second with this method. When the vulnerability was reported to Google, the company marked the issue as "security-sensitive" but "low-priority."' -- source: https://it.slashdot.org/story/18/11/04/0426252 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 CPUs fall to new hyperthreading exploit that pilfers crypto keys
by Peter Reutemann 04 Nov '18

04 Nov '18

'Over the past 11 months, the processors running our computers, and in some cases phones, have succumbed to a host of attacks. Bearing names such as Meltdown and Spectre, BranchScope, TLBleed, and Foreshadow, the exploits threaten to siphon some of our most sensitive secrets—say passwords or cryptographic keys—out of the silicon microarchitecture in ways that can’t be detected or stopped by traditional security defenses. On Friday, researchers disclosed yet another leak that has already been shown to exist on a wide range of Intel chips and may also affect other makers, too. PortSmash, as the new attack is being called, exploits a largely overlooked side-channel in Intel’s hyperthreading technology. A proprietary implementation of simultaneous multithreading, hyperthreading reduces the amount of time needed to carry out parallel computing tasks, in which large numbers of calculations or executions are carried out simultaneously. The performance boost is the result of two logical processor cores sharing the hardware of a single physical processor. The added logical cores make it easier to divide large tasks into smaller ones that can be completed more quickly.' -- source: https://arstechnica.com/information-technology/2018/11/intel-cpus-fall-to-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/

Booting a Raspberry-Pi 3B without using a SD-Card
by Ian Stewart 02 Nov '18

02 Nov '18

Hi, If you have a Raspberry Pi Model 3B, then you may be able use it with no micro SD-Card and have it boot Raspbian off a USB flash drive stick. I have found this possible with an Apacer AH356 64GB USB 3.1 Flash Drive<https://www.pbtech.co.nz/product/MEMAPC11464/Apacer-AH356-64GB-USB-31-Flash…> stick that I bought from PB-Tech a couple of weeks ago for $21.85. Admittedly you can buy a micro SD-card like the Apacer 64GB microSDXC UHS-I Class10<https://www.pbtech.co.nz/product/MEMAPC81064/Apacer-64GB-microSDXC-UHS-I-Cl…> from PB-Tech for $28.75 and put Raspbian onto it. So using the USB flash drive stick only saves a few dollars. However, there may be other advantages over using a USB flash drive vs. a micro SD-Card for the Raspbian OS. For example, you can shutdown the Raspberry Pi and remove the USB stick, take it to another computer, and backup your data. I also installed the Raspbian distro onto WD Elements Portable 2TB 2.5" USB 3.0 External HDD<https://www.pbtech.co.nz/product/HDDWDX2621/WD-Elements-Portable-2TB-25-USB…> which PB-Tech sell for $129. The R-Pi (with no SD-Card) would not boot this drive. Possibly because the USB drive is too slow to initialize after power on??? I also found that the R-Pi would not boot up Raspbian on an old 8GB Kingston USB flash drive. Maybe its too slow to initialize??? All the above tests were done using the current latest Raspbian release which is dated 2018_10_09. FYI: Below are details on how to install the Raspbian distro image onto a USB flash drive stick. cheers, Ian. Installing the Raspbian distro onto USB flash drive... Download the latest 1.4GB Raspbian distribution file: 2018-10-09-raspbian-stretch.zip Unzip the file to create a 4.1GB image file: 2018-10-09-raspbian-stretch.img Copy the 4.1GB image to a USB flash drive stick... $ sudo dd bs=4M if=2018-10-09-raspbian-stretch.img of=/dev/sdX status=progress conv=fsync Note: For the device /dev/sdX replace the X with the drive letter of your USB flash drive stick. e.g. /dev/sdc Insert the USB flash drive stick into the R-Pi model 3B. Remove any SD-Card that may be installed in the Raspberry Pi. Power on the R-Pi. After about 10 seconds the colourful POST display will appear, and the USB stick will commence its first boot. It will detect that it is a 4.1GB partition, expand to being a partition that fills the whole of the USB flash drive stick and reboot. The second reboot will be slow and takes about one minute. I assume it is expanding the squashed file system??? Subsequent reboots are faster.

Blockchain For International Trade
by Lawrence D'Oliveiro 01 Nov '18

ASB is close to offering a general blockchain-based service for international trading payments, starting with this <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=121526…>: ... the transaction was a landmark because the blockchain-based service meant digital payment and paperwork for the deal were wrapped up in an hour - compared to the two to four days it would take to process using more traditional means. Also: Trade is currently paperwork-heavy, Beehre says, making it susceptible to fraud or human error. Which is odd, because isn’t it precisely the point of all that paperwork to reduce the chance of fraud or human error? However: ... blockchain also appealed because of[sic] the technology was created to be unhackable. Every time I hear the word “unhackable”, I reach for my ... never mind.

IBM To Buy Red Hat, the Top Linux Distributor, For $34 Billion
by Peter Reutemann 01 Nov '18

01 Nov '18

'International Business Machines (IBM) is acquiring software maker Red Hat in a deal valued at $34 billion, the companies said Sunday. From a report: The purchase, announced on Sunday afternoon, is the latest competitive step among large business software companies to gain an edge in the fast-growing market for Internet-style cloud computing. In June, Microsoft acquired GitHub, a major code-sharing platform for software developers, for $7.5 billion. IBM said its acquisition of Red Hat was a move to open up software development on computer clouds, in which software developers write applications that run on remote data centers. >From a press release: This acquisition brings together the best-in-class hybrid cloud providers and will enable companies to securely move all business applications to the cloud. Companies today are already using multiple clouds. However, research shows that 80 percent of business workloads have yet to move to the cloud, held back by the proprietary nature of today's cloud market. This prevents portability of data and applications across multiple clouds, data security in a multi-cloud environment and consistent cloud management. IBM and Red Hat will be strongly positioned to address this issue and accelerate hybrid multi-cloud adoption. Together, they will help clients create cloud-native business applications faster, drive greater portability and security of data and applications across multiple public and private clouds, all with consistent cloud management. In doing so, they will draw on their shared leadership in key technologies, such as Linux, containers, Kubernetes, multi-cloud management, and cloud management and automation. IBM's and Red Hat's partnership has spanned 20 years, with IBM serving as an early supporter of Linux, collaborating with Red Hat to help develop and grow enterprise-grade Linux and more recently to bring enterprise Kubernetes and hybrid cloud solutions to customers. These innovations have become core technologies within IBM's $19 billion hybrid cloud business. Between them, IBM and Red Hat have contributed more to the open source community than any other organization.' -- source: https://linux.slashdot.org/story/18/10/28/1859245 That completely flew under the radar! I still remember from my Unix sysadmin course at uni back in the days (using IBM's AIX), when an IBM guy came in for some guest lectures and mentioned that they are ramping up their investment in Linux and also offer Linux next to their own AIX Unix systems. Well, Linux has definitely come a long way!

'Open Source Creators: Red Hat Got $34 Billion and You Got $0. Here's Why.'
by Peter Reutemann 31 Oct '18

31 Oct '18

'Donald Fischer, who served as a product manager for Red Hat Enterprise Linux during its creation and early years of growth, writes: Red Hat saw, earlier than most, that the ascendance of open source made the need to pay for code go away, but the need for support and maintenance grew larger than ever. Thus Red Hat was never in the business of selling software, rather it was in the business of addressing the practical challenges that have always come along for the ride with software. [...] As an open source developer, you created that software. You can keep your package secure, legally documented, and maintained; who could possibly do it better? So why does Red Hat make the fat profits, and not you? Unfortunately, doing business with large companies requires a lot of bureaucratic toil. That's doubly true for organizations that require security, legal, and operational standards for every product they bring in the door. Working with these organizations requires a sales and marketing team, a customer support organization, a finance back-office, and lots of other "business stuff" in addition to technology. Red Hat has had that stuff, but you haven't. And just like you don't have time to sell to large companies, they don't have time to buy from you alongside a thousand other open source creators, one at a time. Sure, big companies know how to install and use your software. (And good news! They already do.) But they can't afford to put each of 1100 npm packages through a procurement process that costs $20k per iteration. Red Hat solved this problem for one corner of open source by collecting 2,000+ open source projects together, adding assurances on top, and selling it as one subscription product. That worked for them, to the tune of billions. But did you get paid for your contributions?' -- source: https://linux.slashdot.org/story/18/10/31/1520256 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 CAP Theorem Strikes Again
by Lawrence D'Oliveiro 31 Oct '18

31 Oct '18

There is a fundamental rule with distributed databases: you can pick any two of: * Maintaining data Consistency across the entire network * Maintaining data Availability across the entire network * Being able to deal with a Partitioning of the network into two or more disconnected pieces but you can never have all three. An example of this is the outage at GitHub earlier this month <https://www.theregister.co.uk/2018/10/31/github_lost_a_network_link_for_43_…>. A link broke between the east-coast and west-coast halves of their network, and in an effort to maintain ongoing service availability on both sides of the partition, they ended up sacrificing consistency of the data. Which came back to bite them when the link was re-established, and the inconsistency could not easily be resolved.

The DNS Encryption Controversy
by Lawrence D'Oliveiro 31 Oct '18

31 Oct '18

There is a rather acrimonious argument currently going on among the Internet technorati over two different competing protocols for implementing encryption of domain name (DNS) queries <https://www.theregister.co.uk/2018/10/30/doh-contorversy/>. One of them is called “DNS-over-TLS” and the other is “DNS-over-HTTPS”. The former passes the DNS queries over its own TLS-encrypted connection, while the latter piggybacks on good old HTTP, using the latter’s TLS capability instead. The former is clearly simpler, and one might say “purer”, but the latter is deliberately designed to make it hard to tell what DNS queries a user might be making, since they become indistinguishable from regular HTTPS connections. So the question becomes, do you see this obfuscation as a good thing or a bad thing? It is intended to prevent snoops (both Governmental and non-Governmental) from invading the privacy of users, but it also blocks “legitimate” analysis of traffic by network admins trying to manage their systems as well. Clearly, you can’t do one without the other. So is the price worth paying?

Easy-to-exploit privilege escalation bug bites OpenBSD and other big name OSes
by Peter Reutemann 29 Oct '18

29 Oct '18

'Several big-name Linux and BSD operating systems are vulnerable to an exploit that gives untrusted users powerful root privileges. The critical flaw in the X.org server—the open-source implementation of the X11 system that helps manage graphics displays—affects OpenBSD, widely considered to be among the most secure OSes. It also impacts some versions of the Red Hat, Ubuntu, Debian, and CentOS distributions of Linux. An advisory X.org developers published Thursday disclosed the 23-month-old bug that, depending on how OS developers configure it, lets hackers or untrusted users elevate very limited system rights to unfettered root. The vulnerability, which is active when OSes run X.org in privileged (setuid) mode, allows files to be overwritten using the -logfile and -modulepath parameters. It also makes it trivial for low-privilege users to escalate system rights. A variety of nuances are leading to widely divergent assessments of the bug's severity. “Depending on whom you talk to, the reported severity will vary greatly,” Louis Dion-Marcil, a security researcher at GoSecure, told Ars. “I think most people will tell you it is very severe, and I would agree with them. The bug allows you to write arbitrary data to arbitrary files, which might seem trivial and not that dangerous, but it effectively allows regular, unprivileged users to elevate their privileges to the one of complete administrator of the system.”' -- source: https://arstechnica.com/information-technology/2018/10/x-org-bug-that-gives… 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 SystemD Vulnerability Discovered
by Peter Reutemann 28 Oct '18

28 Oct '18

'The Register reports that a new security bug in systemd "can be exploited over the network to, at best, potentially crash a vulnerable Linux machine, or, at worst, execute malicious code on the box" by a malicious host on the same network segment as the victim. According to one Red Hat security engineer, "An attacker could exploit this via malicious DHCP server to corrupt heap memory on client machines, resulting in a denial of service or potential code execution." According to the bug description, systemd-networkd "contains a DHCPv6 client which is written from scratch and can be spawned automatically on managed interfaces when IPv6 router advertisements are received." OneHundredAndTen shared this article from the Register: In addition to Ubuntu and Red Hat Enterprise Linux, systemd has been adopted as a service manager for Debian, Fedora, CoreOS, Mint, and SUSE Linux Enterprise Server. We're told RHEL 7, at least, does not use the vulnerable component by default. Systemd creator Leonard Poettering has already published a security fix for the vulnerable component -- this should be weaving its way into distros as we type. If you run a systemd-based Linux system, and rely on systemd-networkd, update your operating system as soon as you can to pick up the fix when available and as necessary.' -- source: https://news.slashdot.org/story/18/10/27/196227 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 and Google Drive: random download locations?
by Peter Reutemann 25 Oct '18

Hi everyone In case you're using Google Drive frequently in conjunction with Firefox and always wondered about the random download locations (when "always ask" is enabled), I just found the reason for this... Firefox has a boolean setting "browser.download.lastDir.savePerSite" (not defined by default) that defines whether to remember the download location per site. However, with Google Drive, you will get a random URL serving the file, turning the last known download directory into a useless feature unfortunately. So, just go into "about:config", and create the above mentioned boolean setting and use "false" as the value. Now you have a "global" last known download location. -- source: https://support.mozilla.org/en-US/questions/925960 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 Study Claims Data Harvesting Among Android Apps Is 'Out of Control'
by Peter Reutemann 25 Oct '18

25 Oct '18

'A new study from Oxford University revealed that almost 90 percent of free apps on the Google Play store share data with Alphabet. "The researchers, who analyzed 959,000 apps from the U.S. and UK Google Play stores, said data harvesting and sharing by mobile apps was now 'out of control,'" reports TechSpot. "'We find that most apps contain third party tracking, and the distribution of trackers is long-tailed with several highly dominant trackers accounting for a large portion of the coverage,' reads the report." From the report: It's revealed that most of the apps, 88.4 percent, could share data with companies owned by Google parent Alphabet. Next came a firm that's no stranger to data sharing controversies, Facebook (42.5 percent), followed by Twitter (33.8 percent), Verizon (26.27 percent), Microsoft (22.75 percent), and Amazon (17.91 percent). [I]nformation shared by these third-party apps can include age, gender, location, and information about a user's other installed apps. The data "enables construction of detailed profiles about individuals, which could include inferences about shopping habits, socio-economic class or likely political opinions." Big firms then use the data for a variety of purposes, such as credit scoring and for targeting political messages, but its main use is often ad targeting. Not surprising, given that revenue from online advertising is now over $59 billion per year. According to the research, the average app transfers data to five tracker companies, which pass the data on to larger firms. The biggest culprits are news apps and those aimed at children, both of which tend to have the most third-party trackers associated with them.' -- source: https://yro.slashdot.org/story/18/10/24/2340207 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 News App Bug Is Using Up Gigabytes of Background Data Without Users' Knowledge
by Peter Reutemann 23 Oct '18

23 Oct '18

'A bug in the Google News app for Android is reportedly causing the app to use up excessive amounts of background data, leading to overage charges. "According to dozens of posts on the Google News Help Forum, users have been experiencing this issue as early as June," reports The Verge. "The issue was verified and addressed by a Google News community manager in September, stating that the company was investigating and working toward a fix, but the issue is still ongoing." From the report: Verge reader Zach Dowdle emailed in with his experience, and screenshots of his app and Wi-Fi data usage: "The Google News app is randomly using a ridiculous amount of background data without users' knowledge. The app burned through over 12 gigs of data on my phone while I slept and my Wi-Fi had disconnected. It lead to $75 in overage charges." According to several users, the app burned through mobile data despite having "Download via Wi-Fi" turned on in the settings. In some extreme cases, the Google News app used up to 24GB of data, leading to overage charges of up to $385, users reported. So far, the only solutions seem to be disabling background data, and deleting the app altogether.

Mozilla Is Reportedly Going To Sell VPN Subscriptions Within Firefox
by Peter Reutemann 23 Oct '18

23 Oct '18

'Mozilla is reportedly preparing to offer a VPN service for Firefox users to help protect them when surfing the web. According to Trusted Reviews, Mozilla has partnered with the ProtonVPN service, "with a new notification piping-up when the browser detects an unsecured connection, or in a scenario when VPN might be preferable to users." >From the report: However, it appears Firefox users will have to pay for the privilege. Austrian site Soeren-hentzschel reports the premium VPN service will be $10 a month, which is what ProtonVPN charges its users. Users will receive a "Firefox Recommends" pop-up when browsing an unsecured wireless network. The pop-up says the VPN service will provide a "private and secure' internet connection. According to the reports, a subset of Firefox 62 users in the United States will begin receiving the pop-up from today. Mozilla will reportedly get a cut of any subscription fee handed over by users to access the VPN service. MSPowerUser points out that this will be the first advertised service that costs money for Firefox users.' -- source: https://tech.slashdot.org/story/18/10/23/0351220 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 63 Arrives With Enhanced Tracking Protection, Search Shortcuts, and Picture-in-Picture on Android
by Peter Reutemann 23 Oct '18

23 Oct '18

'Mozilla today launched Firefox 63 for Windows, Mac, Linux, and Android. The release brings Enhanced Tracking Protection, performance improvements on Windows and macOS, search shortcuts, and Picture-In-Picture on Android. From a report: Firefox 63 for the desktop is available for download now on Firefox.com, and all existing users should be able to upgrade to it automatically. As always, the Android version is trickling out slowly on Google Play. According to Mozilla, Firefox has about 300 million active users. In other words, it's a major platform that web developers must consider. Firefox 63 for desktop brings support for Enhanced Tracking Protection. [...] Firefox 63's Enhanced Tracking Protection blocks cookies and storage access from third-party trackers, which Mozilla says targets the problem of cross-site tracking without breaking sites and impacting revenue streams like the original Tracking Protection. It does this by preventing known trackers from setting third-party cookies -- the primary method of tracking across sites -- but still gives you the option to block all known trackers (under Firefox Options/Preferences). [...] Search shortcuts essentially pins sites like Google and Amazon on the new tab page. When you click or tap them, you're redirected to Firefox's awesome bar, which automatically fills the corresponding keyword (@google or @amazon in this case) for the search engine. This way, you can type your query, hit enter, and get your search results without having to first load the Google or Amazon homepage. [...] The only major new feature for this Firefox for Android release is a picture-in-picture mode (Android Oreo and up). This means that if you're watching a video in full-screen, when you switch away from Firefox it will move the video into a small floating window, which you can tap to return to the full video player.' -- source: https://news.slashdot.org/story/18/10/23/149223 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 Announces GNU Kind Communication Guidelines
by Peter Reutemann 23 Oct '18

23 Oct '18

'Richard Stallman has announced the GNU Kind Communication Guidelines, an effort "to start guiding people towards kinder communication." The Guidelines differ from a Code of Conduct in that it's trying to be proactive about kindness around free software development over being rules with possible actions when breaking them. These new GNU communication guidelines can be found at GNU.org along with Stallman's commentary. >From the guidelines: A code of conduct states rules, with punishments for anyone that violates them. It is the heavy-handed way of teaching people to behave differently, and since it only comes into action when people do something against the rules, it doesn't try to teach people to do better than what the rules require. To be sure, the appointed maintainer(s) of a GNU package can, if necessary, tell a contributor to go away; but we do not want to need to have recourse to that. The idea of the GNU Kind Communication Guidelines is to start guiding people towards kinder communication at a point well before one would even think of saying, "You are breaking the rules." The way we do this, rather than ordering people to be kind or else, is try to help people learn to make their communication more kind. I hope that kind communication guidelines will provide a kinder and less strict way of leading a project's discussions to be calmer, more welcoming to all participants of good will, and more effective.' -- source: https://news.slashdot.org/story/18/10/23/1418225 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/

Now Apps Can Track You Even After You Uninstall Them
by Peter Reutemann 22 Oct '18

22 Oct '18

'If it seems as though the app you deleted last week is suddenly popping up everywhere, it may not be mere coincidence. From a report: Companies that cater to app makers have found ways to game both iOS and Android, enabling them to figure out which users have uninstalled a given piece of software lately -- and making it easy to pelt the departed with ads aimed at winning them back. Adjust, AppsFlyer, MoEngage, Localytics, and CleverTap are among the companies that offer uninstall trackers, usually as part of a broader set of developer tools. Their customers include T-Mobile US, Spotify Technology, and Yelp. Critics say they're a fresh reason to reassess online privacy rights and limit what companies can do with user data. "Most tech companies are not giving people nuanced privacy choices, if they give them choices at all," says Jeremy Gillula, tech policy director at the Electronic Frontier Foundation, a privacy advocate. Some providers say these tracking tools are meant to measure user reaction to app updates and other changes. Jude McColgan, chief executive officer of Boston's Localytics, says he hasn't seen clients use the technology to target former users with ads. Ehren Maedge, vice president for marketing and sales at MoEngage Inc. in San Francisco, says it's up to the app makers not to do so. "The dialogue is between our customers and their end users," he says. "If they violate users' trust, it's not going to go well for them." Adjust, AppsFlyer, and CleverTap didn't respond to requests for comment, nor did T-Mobile, Spotify, or Yelp. Uninstall tracking exploits a core element of Apple's and Google's mobile operating systems: push notifications. Developers have always been able to use so-called silent push notifications to ping installed apps at regular intervals without alerting the user -- to refresh an inbox or social media feed while the app is running in the background, for example. But if the app doesn't ping the developer back, the app is logged as uninstalled, and the uninstall tracking tools add those changes to the file associated with the given mobile device's unique advertising ID, details that make it easy to identify just who's holding the phone and advertise the app to them wherever they go.' -- source: https://yro.slashdot.org/story/18/10/22/1956257 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/

Linus Torvalds is Back in Charge of Linux
by Peter Reutemann 22 Oct '18

22 Oct '18

'At Open Source Summit Europe in Edinburgh, Scotland, Linus Torvalds is meeting with Linux's top 40 or so developers at the Maintainers' Summit. This is his first step back in taking over Linux's reins. From a report: A little over a month ago, Torvalds has stepped back from running the Linux development community. Then, in a note to the Linux Kernel Mailing List (LKML), Torvalds has said, "I need to change some of my behavior, and I want to apologize to the people that my personal behavior hurt and possibly drove away from kernel development entirely." To do, this he took time off "to change some of my behavior, and I want to apologize to the people that my personal behavior hurt and possibly drove away from kernel development entirely. I am going to take time off and get some assistance on how to understand people's emotions and respond appropriately." That time is over. Torvalds is back. Whether he'll be a kinder and gentler Torvalds remains to be seen. In the Linux 4.19 announcement, Greg Kroah-Hartman, Linux's temporary leader and maintainer of the stable branch, wrote: "Linus, I'm handing the kernel tree back to you. You can have the joy of dealing with the merge window :)"' -- source: https://linux.slashdot.org/story/18/10/22/1145234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

After $5 billion EU antitrust fine, Google will start charging for Android apps
by Peter Reutemann 17 Oct '18

17 Oct '18

'Google is adjusting to life in the EU after the $5.05 billion (€4.34 billion) antitrust fine levied against it by the European Commission earlier this year. Google is still appealing the initial ruling, which found that Google used Android to illegally dominate the search market, but for now Google will comply with the ruling and offer looser licensing agreements to Android device makers. In a post on the official Google Blog titled "Complying with the EC’s Android decision," Google outlined a few changes coming to the Google app licensing agreements that it offers to Android OEMs. As you might recall from the numerous times we've written about it, this announcement is a change to the secretive "Mobile Application Distribution Agreement" (MADA) document that is a requirement for getting access to the Play Store and other Google apps. What we think of as a commercial "Android" device comes in two parts. The core Android OS is free and open source—anyone can take it and do whatever they want with it without Google's involvement. If you want the Play Store, Google Maps, Gmail, and all the other Google apps you need to make a viable commercial smartphone, though, you need to talk to Google and sign a MADA, which comes with a ton of restrictions. Google's new MADA makes three big changes. First, Google's blog states "Android partners wishing to distribute Google apps may also build non-compatible, or forked, smartphones and tablets for the European Economic Area (EEA)." [...] Google says it will also unbundle Search and Chrome from the rest of the Google apps. [...] The last change is definitely a shocker. Breaking up Google's licensing agreement is going to have a financial impact on OEMs. As Google puts it, "Since the pre-installation of Google Search and Chrome together with our other apps helped us fund the development and free distribution of Android, we will introduce a new paid licensing agreement for smartphones and tablets shipped into the EEA." That's right, OEMs now have to pay to access the Google apps, but Google doesn't say how much. The core Android OS, Google says "will remain free and open source."

Researcher Finds Simple Way of Backdooring Windows PCs and Nobody Notices for Ten Months
by Peter Reutemann 17 Oct '18

17 Oct '18

' A security researcher from Colombia has found a way of gaining admin rights and boot persistence on Windows PCs that's simple to execute and hard to stop -- all the features that hackers and malware authors are looking for from an exploitation technique. From a report: What's more surprising, is that the technique was first detailed way back in December 2017, but despite its numerous benefits and ease of exploitation, it has not received either media coverage nor has it been seen employed in malware campaigns. Discovered by Sebastian Castro, a security researcher for CSL, the technique targets one of the parameters of Windows user accounts known as the Relative Identifier (RID). The RID is a code added at the end of account security identifiers (SIDs) that describes that user's permissions group. There are several RIDs available, but the most common ones are 501 for the standard guest account, and 500 for admin accounts. Castro, with help from CSL CEO Pedro Garcia, discovered that by tinkering with registry keys that store information about each Windows account, he could modify the RID associated with a specific account and grant it a different RID, for another account group. The technique does not allow a hacker to remotely infect a computer unless that computer has been foolishly left exposed on the Internet without a password. But in cases where a hacker has a foothold on a system -- via either malware or by brute-forcing an account with a weak password -- the hacker can give admin permissions to a compromised low-level account, and gain a permanent backdoor with full SYSTEM access on a Windows PC.' -- source: https://it.slashdot.org/story/18/10/17/1849255 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/

Former Top Waymo Engineer Altered Code To Go on 'Forbidden Routes', Report Says
by Peter Reutemann 17 Oct '18

17 Oct '18

'In the early days of what ultimately became Waymo, Google's self-driving car division (known at the time as "Project Chauffeur"), there were "more than a dozen accidents, at least three of which were serious," according to a new article in The New Yorker . From a report: The magazine profiled Anthony Levandowski, the former Google engineer who was at the center of the Waymo v. Uber trade secrets lawsuit. According to the article, back in 2011, Levandowski also modified the autonomous software to take the prototype Priuses on "otherwise forbidden routes." Citing an anonymous source, The New Yorker reports that Levandowski sat behind the wheel as the safety driver, along with Isaac Taylor, a Google executive. But while they were in the car, the Prius "accidentally boxed in another vehicle," a Camry. As The New Yorker wrote: "A human driver could easily have handled the situation by slowing down and letting the Camry merge into traffic, but Google's software wasn't prepared for this scenario. The cars continued speeding down the freeway side by side. The Camry's driver jerked his car onto the right shoulder. Then, apparently trying to avoid a guard rail, he veered to the left; the Camry pinwheeled across the freeway and into the median. Levandowski, who was acting as the safety driver, swerved hard to avoid colliding with the Camry, causing Taylor to injure his spine so severely that he eventually required multiple surgeries." This was apparently just one of several accidents in Project Chauffeur's early days.' -- source: https://tech.slashdot.org/story/18/10/17/204215 Just another reason why self-driving cars should be open-sourced...

MongoDB Switches Up Its Open-Source License
by Peter Reutemann 17 Oct '18

17 Oct '18

'MongoDB is taking action against cloud giants who are taking its open-source code and offering a hosted commercial version of its database to their users without playing by the open-source rules. The company announced today that it has issued a new software license, the Server Side Public License (SSPL), "that will apply to all new releases of its MongoDB Community Server, as well as all patch fixes for prior versions," reports TechCrunch. From the report: For virtually all regular users who are currently using the community server, nothing changes because the changes to the license don't apply to them. Instead, this is about what MongoDB sees as the misuse of the AGPLv3 license. "MongoDB was previously licensed under the GNU AGPLv3, which meant companies who wanted to run MongoDB as a publicly available service had to open source their software or obtain a commercial license from MongoDB," the company explains. "However, MongoDB's popularity has led some organizations to test the boundaries of the GNU AGPLv3." So while the SSPL isn't all that different from the GNU GPLv3, with all the usual freedoms to use, modify and redistribute the code (and virtually the same language), the SSPL explicitly states that anybody who wants to offer MongoDB as a service -- or really any other software that uses this license -- needs to either get a commercial license or open source the service to give back the community. "The market is increasingly consuming software as a service, creating an incredible opportunity to foster a new wave of great open source server-side software. Unfortunately, once an open source project becomes interesting, it is too easy for cloud vendors who have not developed the software to capture all of the value but contribute nothing back to the community," said Eliot Horowitz, the CTO and co-founder of MongoDB, in a statement. "We have greatly contributed to -- and benefited from -- open source and we are in a unique position to lead on an issue impacting many organizations. We hope this will help inspire more projects and protect open source innovation."' -- source: https://developers.slashdot.org/story/18/10/16/2039253 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/

So It’s Not Just Me

Given the number of tech-support scam calls I’ve been getting, I was starting to feel picked on. But it turns out it’s New Zealand as a whole that’s being picked on, with “more than three-quarters” of Kiwis sampled in a Microsoft study reporting that they had been targeted by these scammers <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=121434…>. We are also more likely than any other nation (out of the 16 that took part in the survey) to experience fake popup browser notifications. But then, thinking about it, the “global average” of 62% of respondents getting the scam attempts smells rather strongly of sampling bias to me. It’s hard to believe that nearly two-thirds of the entire world population has been getting these calls ...

Rivals ARM and Intel Make Peace To Secure Internet of Things
by Peter Reutemann 15 Oct '18

15 Oct '18

'Rival semiconductor giants ARM and Intel have agreed to work together to manage networks of connected devices from both firms, clearing a major stumbling block to market growth of the so-called Internet of Things (IoT). From a report: Britain's ARM, a unit of Japan's Softbank, said on Monday it had struck a strategic partnership with Intel to use common standards developed by Intel for managing IoT devices, connections and data. The IoT involves connecting simple chips that detect distance, motion, temperature, pressure and images to be used in an ever wider range of electronics such as lights, parking meters or refrigerators. Some of the world's dumbest electronics devices get smarter by becoming connected into cloud networks, but also harder to protect. ARM's agreement to adopt Intel standards for securely managing such networks marks a breakthrough that promises to drive the spread of IoT across many industries, the two companies said.' -- source: https://it.slashdot.org/story/18/10/15/1338259 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/

Software Freedom Conservancy Shares Thoughts on Microsoft Joining Open Invention Network's Patent Non-Aggression Pact
by Peter Reutemann 14 Oct '18

14 Oct '18

'Earlier this week, Microsoft announced that it was joining the open-source patent consortium Open Invention Network (OIN). The press release the two shared this week was short on details on how the two organizations intend to work together and what does the move mean to, for instance, the billions of dollars Microsoft earns each year from its Android patents (since Google is a member of OIN, too.) Software Freedom Conservancy (SFC), a non-profit organization that promotes open-source software, has weighed in on the subject: While [this week's] announcement is a step forward, we call on Microsoft to make this just the beginning of their efforts to stop their patent aggression efforts against the software freedom community. The OIN patent non-aggression pact is governed by something called the Linux System Definition. This is the most important component of the OIN non-aggression pact, because it's often surprising what is not included in that Definition especially when compared with Microsoft's patent aggression activities. Most importantly, the non-aggression pact only applies to the upstream versions of software, including Linux itself. We know that Microsoft has done patent troll shakedowns in the past on Linux products related to the exfat filesystem. While we at Conservancy were successful in getting the code that implements exfat for Linux released under GPL (by Samsung), that code has not been upstreamed into Linux. So, Microsoft has not included any patents they might hold on exfat into the patent non-aggression pact. We now ask Microsoft, as a sign of good faith and to confirm its intention to end all patent aggression against Linux and its users, to now submit to upstream the exfat code themselves under GPLv2-or-later. This would provide two important protections to Linux users regarding exfat: (a) it would include any patents that read on exfat as part of OIN's non-aggression pact while Microsoft participates in OIN, and (b) it would provide the various benefits that GPLv2-or-later provides regarding patents, including an implied patent license and those protections provided by GPLv2 (and possibly other GPL protections and assurances as well).' -- source: https://yro.slashdot.org/story/18/10/14/2140221 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 OS That Did Too Much
by Lawrence D'Oliveiro 13 Oct '18

13 Oct '18

You may have heard of the recent Windows 10 update (now withdrawn) that was causing some users to lose their files. There is an analysis of the problem, reported here <https://www.theregister.co.uk/2018/10/10/microsoft_windows_deletion_bug/>. It was a consequence of a feature known as “Known Folder Redirection”, which it seems only exists because of the drive-letter limitations of Windows. The closest analogue might be Linux mount points or symlinks, only the Windows version is more complicated, in usual Microsoft fashion. One mystery is that the bug was reported by multiple testers months before release, yet it seems their reports were ignored.

Facebook Offers Update On Recent Hack — And It's Bad. Here's How To Find Out If You Were Affected And What It Means
by Peter Reutemann 13 Oct '18

13 Oct '18

'Late last month Facebook announced the service had been hacked, resulting in the theft of data from 50 million users. Today Facebook finally issued an update on what the company's continuing investigation has found regarding the scale and scope of the attack. While the official press release presents the findings in a matter-of-fact manner, tech reporters have been quick to point out that the actual risks posed by what the attackers possess are alarming. The hackers used an exploit particular to the "View As" feature that allowed them to steal access tokens, letting the hackers take over accounts they did not already possess the passwords to. Facebook's press release notes that "the attackers already controlled a set of accounts, which were connected to Facebook friends." Starting by taking over friends of those initial accounts, the hackers stole tokens for "about 400,000" accounts. From there, the hackers used a portion of those accounts' friend lists to take over 30 million accounts. The press release is quick to note that this is less than Facebook's initial assessment that 50 million accounts had been compromised ("about 30 million actually had their tokens stolen," emphasis Facebook's).' -- source: http://digg.com/2018/facebook-hack-30-million-users-contact-info-2fa 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 Rebukes Australia's 'Dangerously Ambiguous' Anti-Encryption Bill
by Peter Reutemann 13 Oct '18

13 Oct '18

'Apple has strongly criticized Australia's anti-encryption bill, calling it "dangerously ambiguous" and "alarming to every Australian." >From a report: The Australian government's draft law -- known as the Access and Assistance Bill -- would compel tech companies operating in the country, like Apple, to provide "assistance" to law enforcement and intelligence agencies in accessing electronic data. The government claims that encrypted communications are "increasingly being used by terrorist groups and organized criminals to avoid detection and disruption," without citing evidence. But critics say that the bill's "broad authorities that would undermine cybersecurity and human rights, including the right to privacy" by forcing companies to build backdoors and hand over user data -- even when it's encrypted. Now, Apple is the latest company after Google and Facebook joined civil and digital rights groups -- including Amnesty International -- to oppose the bill, amid fears that the government will rush through the bill before the end of the year. In a seven-page letter to the Australian parliament, Apple said that it "would be wrong to weaken security for millions of law-abiding customers in order to investigate the very few who pose a threat." The company adds, "We appreciate the government's outreach to Apple and other companies during the drafting of this bill. While we are pleased that some of the suggestions incorporated improve the legislation, the unfortunate fact is that the draft legislation remains dangerously ambiguous with respect to encryption and security. This is no time to weaken encryption. Rather than serving the interests of Australian law enforcement, it will just weaken the security and privacy of regular customers while pushing criminals further off the grid."' -- source: https://apple.slashdot.org/story/18/10/12/1856202 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A Mysterious Grey-Hat Is Patching People's Outdated MikroTik Routers
by Peter Reutemann 13 Oct '18

13 Oct '18

'A Russian-speaking grey-hat hacker is breaking into people's MikroTik routers and patching devices so they can't be abused by cryptojackers, botnet herders, or other cyber-criminals, ZDNet has learned. The hacker, who goes by the name of Alexey and says he works as a server administrator, claims to have disinfected over 100,000 MikroTik routers already. "I added firewall rules that blocked access to the router from outside the local network," Alexey said. "In the comments, I wrote information about the vulnerability and left the address of the @router_os Telegram channel, where it was possible for them to ask questions." But despite adjusting firewall settings for over 100,000 users, Alexey says that only 50 users reached out via Telegram. A few said "thanks," but most were outraged. The vigilante server administrator says he's been only fixing routers that have not been patched by their owners against a MikroTik vulnerability that came to light in late April.' -- source: https://mobile.slashdot.org/story/18/10/12/2052202 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/

Over Nine Million Cameras and DVRs Open To APTs, Botnet Herders, and Voyeurs
by Peter Reutemann 11 Oct '18

11 Oct '18

'Millions of security cameras, DVRs, and NVRs contain vulnerabilities that can allow a remote attacker to take over devices with little effort, security researchers have revealed today. From a report: All vulnerable devices have been manufactured by Hangzhou Xiongmai Technology Co., Ltd. (Xiongmai hereinafter), a Chinese company based in the city of Hangzhou. But end users won't be able to tell that they're using a hackable device because the company doesn't sell any products with its name on them, but ships all equipment as white label products on which other companies put their logo on top. Security researchers from EU-based SEC Consult say they've identified over 100 companies that buy and re-brand Xiongmai devices as their own. All of these devices are vulnerable to easy hacks, researchers say. The source of all vulnerabilities is a feature found in all devices named the "XMEye P2P Cloud." The XMEye P2P Cloud works by creating a tunnel between a customer's device and an XMEye cloud account. Device owners can access this account via their browser or via a mobile app to view device video feeds in real time. SEC Consult researchers say that these XMEye cloud accounts have not been sufficiently protected. For starters, an attacker can guess account IDs because they've been based on devices' sequential physical addresses (MACs). Second, all new XMEye accounts use a default admin username of "admin" with no password.' -- source: https://yro.slashdot.org/story/18/10/11/1925256 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/

Plex for Linux Now Available as a Snap
by Peter Reutemann 11 Oct '18

11 Oct '18

'Today, a very popular app, Plex Media Server, gets the Snap treatment. In other words, you can install the media server program without any headaches -- right from the Snap store. "In adopting the universal Linux app packaging format, Plex will make its multimedia platform available to an ever-growing community of Linux users, including those on KDE Neon, Debian, Fedora, Manjaro, OpenSUSE, Zorin and Ubuntu. Automatic updates and rollback capabilities are staples of Snap software, meaning Plex users will always have the best and latest version running," says Canonical.' -- source: https://linux.slashdot.org/story/18/10/11/193246 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/
