SoftBank and the 300-year plan
by Ian Young 17 May '19

17 May '19

Perhaps some may not have seen these recent articles about SoftBank which owns ARM. The most detailed I have come across so far. The SoftBank CEO has a 300-year plan it seems. Even the 2035 plan is spectacular. "By 2035 there will be a trillion connected devices, he [Son] said – a vast Internet of Things of autonomous vehicles, smart robots and artificially intelligent sensors, and Arm would be the company behind all these devices." https://www.wired.co.uk/article/softbank-vision-fund https://www.fastcompany.com/90285552/the-most-powerful-person-in-silicon-va…

Wi-Fi Transmission Overhead?
by Lawrence D'Oliveiro 16 May '19

16 May '19

I’m currently copying a few gigabytes of files from my main workstation onto my laptop via wi-fi. Looking at dstat, on the workstation, it is reading about 4MB/s from the disk, but the network data transmission rate is a bit over twice that, more like 9MB/s. At the laptop end, it is receiving about 4MB/s over the network, which more closely matches the data being read from disk on the transmit side, but not the transmission rate. Has anybody else seen something similar?

SSH Password-Guessing Attacks
by Lawrence D'Oliveiro 16 May '19

16 May '19

I suppose you know that if you put a machine on the Internet with an SSH server listening on port 22, you are going to get bombarded with password-guessing login attempts. Previously, I thought that moving the SSH server to a nonstandard port was sufficient to block these. But now I am seeing these attacks happening on my Rimu VPS anyway. Should I bother to change the port again?

Why Linux On Desktop 'Failed': A Discussion With Mark Shuttleworth
by Peter Reutemann 15 May '19

15 May '19

'Mark Shuttleworth, founder and CEO of Canonical, summed it in a few words: "I think the bigger challenge has been that we haven't invented anything in the Linux that was like deeply, powerfully ahead of its time." He also said that "if in the free software community we only allow ourselves to talk about things that look like something that already exists, then we're sort of defining ourselves as a series of forks and fragmentations." He added that it seems the desktop Linux people want to be angry at something. We wanted to do amazing things with Unity but the community won't let us do it, so here we are. He also commended Google folks for what they have built for Chrome OS.' -- source: https://linux.slashdot.org/story/19/05/15/1523252 Hmm... Multiple virtual desktops, natively supported Windows, finally available with Windows 10 (though terrible to use!). Even fvwm2 in 1998 or 1999 was better than Windows' current implementation...

Google Recalls Its Bluetooth Titan Security Keys Because of a Security Bug
by Peter Reutemann 15 May '19

15 May '19

'Google today disclosed a security bug in its Bluetooth Titan Security Key that could allow an attacker in close physical proximity to circumvent the security the key is supposed to provide. From a report: The company says that the bug is due to a "misconfiguration in the Titan Security Keys' Bluetooth pairing protocols" and that even the faulty keys still protect against phishing attacks. Still, the company is providing a free replacement key to all existing users. The bug affects all Titan Bluetooth keys, which sell for $50 in a package that also includes a standard USB/NFC key, that have a "T1" or "T2" on the back.' -- source: https://it.slashdot.org/story/19/05/15/1728202 Rather than "Titan", they should have called it "Achilles"... ;-) 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 Long Dual-Booting Windows on a Chromebook: Project Campfire is deprecated
by Peter Reutemann 15 May '19

15 May '19

'Project Campfire turned up in the Chromium world this past August. The intent was to let a Chromebook boot not just into Chrome OS but directly into another operating system such as Linux or Windows. I thought the latter was a positive outcome since it would allow Chromebooks to natively run Windows desktop apps on a Chromebook, and add value to devices. Unfortunately, the project is shutting down. Spotted in code, there are comments and code removals that make it clear Project Campfire is being deprecated.' -- source: https://linux.slashdot.org/story/19/05/15/1752208 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 Is About To Have a Lot More Ads On Phones
by Peter Reutemann 14 May '19

14 May '19

'The Verge reports on the new ad types Google announced today that will start showing up throughout its mobile products, including some that interrupt the core Google search and discovery experiences. From the report: Google searches on mobile will soon include "gallery" ads that allow advertisers to display multiple images for users to swipe through. You'll also begin to see ads in Google's discover feed -- the feed of news stories that you find built into many Android home screens, inside the Google app, and on Google's mobile homepage -- though they'll only appear in select locations for now. The new ad formats are meant to make ads a lot more noticeable. In a blog post, Google ad chief Prabhakar Raghavan says that, in tests, gallery ads resulted in "up to 25 percent more interactions" than traditional search ads. Gallery ads will only be launching on mobile, not the desktop. Discover ads will appear in Google's mobile app, as well as on the discover feed on Android phones. Google tells us those ads won't appear in the discover feed that's built into the google.com mobile homepage. [...] The discover feed -- a personalized feed of recommended news stories that Google displays on mobile -- will also be getting ads for the first time. They'll appear just like any other story, with an image on top, a headline, and a subject field with more information. But they'll have a small badge that says "ad" to let users know it's sponsored. Those ads will extend to YouTube as well, where they'll slot in alongside recommended videos. Discover ads will also roll out later this year.

Microsoft Patches 'Wormable' Flaw in Windows XP, 7 and Windows 2003
by Peter Reutemann 14 May '19

14 May '19

'Microsoft today is taking the unusual step of releasing security updates for unsupported but still widely-used Windows operating systems like XP and Windows 2003, citing the discovery of a "wormable" flaw that the company says could be used to fuel a fast-moving malware threat like the WannaCry ransomware attacks of 2017. From a report: The vulnerability (CVE-2019-0708) resides in the "remote desktop services" component built into supported versions of Windows, including Windows 7, Windows Server 2008 R2, and Windows Server 2008. It also is present in computers powered by Windows XP and Windows 2003, operating systems for which Microsoft long ago stopped shipping security updates. Microsoft said the company has not yet observed any evidence of attacks against the dangerous security flaw, but that it is trying to head off a serious and imminent threat.' -- source: https://tech.slashdot.org/story/19/05/14/1943243 A bit like "what is dead may never die"... ;-) Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Hard-To-Fix' Cisco Flaw Puts Work Email At Risk
by Peter Reutemann 14 May '19

14 May '19

'Security researchers have discovered serious vulnerabilities affecting dozens of Cisco devices. The flaws allow hackers to deceive the part of the product hardware that checks whether software updates come from legitimate sources. Experts believe this could put emails sent within an organization at risk as they may use compromised routers. Messages sent externally constitute less of a risk, however, as they tend to be encrypted. The California-based firm said it is working on "software fixes" for all affected hardware. "We've shown that we can quietly and persistently disable the Trust Anchor," Red Balloon chief executive Ang Cui, told Wired magazine. "That means we can make arbitrary changes to a Cisco router, and the Trust Anchor will still report that the device is trustworthy. Which is scary and bad, because this is in every important Cisco product. Everything." Security experts believe that the vulnerability could cause a major headache for Cisco, which has listed dozens of its products as vulnerable on its website. "We don't know how many devices could have been affected and it's unlikely Cisco can tell either," said Prof Alan Woodward, a computer security expert based at Surrey University. "It could cost Cisco a lot of money."' -- source: https://it.slashdot.org/story/19/05/14/1945212 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 Released in Last 8 Years Impacted by New Zombieload Side-Channel Attack
by Peter Reutemann 14 May '19

14 May '19

'Academics have discovered a new class of vulnerabilities in Intel processors that can allow attackers to retrieve data being processed inside a CPU. From a report: The leading attack in this new vulnerability class is a security flaw named Zombieload, which is another side-channel attack in the same category as Meltdown, Spectre, and Foreshadow. Just like the first three, Zombieload is exploited by taking advantage of the speculative execution process, which is an optimization technique that Intel added to its CPUs to improve data processing speeds and performance. For more than a year, academics have been poking holes in various components of the speculative execution process, revealing ways to leak data from various CPU buffer zones and data processing operations. Meltdown, Spectre, and Foreshadow have shown how various CPU components leak data during the speculative execution process. Today, an international team of academics -- including some of the people involved in the original Meltdown and Spectre research -- along with security researchers from Bitdefender have disclosed a new attack impacting the speculative execution process. This one is what researchers have named a Microarchitectural Data Sampling (MDS) attack, and targets a CPU's microarchitectural data structures, such as the load, store, and line fill buffers, which the CPU uses for fast reads/writes of data being processed inside the CPU. [...] In a research paper published today, academics say that all Intel CPUs released since 2011 are most likely vulnerable. Processors for desktops, laptops, and (cloud) servers are all impacted, researchers said on a special website they've set up with information about the Zombieload flaws.' -- source: https://tech.slashdot.org/story/19/05/14/1721242 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Academics Improve SHA-1 Collision Attack, Make It Actually Dangerous
by Peter Reutemann 14 May '19

14 May '19

'"Attacks on the SHA-1 hashing algorithm just got a lot more dangerous last week with the discovery of the first-ever 'chosen-prefix collision attack,' a more practical version of the SHA-1 collision attack first carried out by Google two years ago," reports ZDNet. Google's original research allowed attackers to force duplicates for specific files, but this process was often at random. A new SHA-1 collision attack variation (a chosen-prefix attack) detailed last week allows attackers to choose what SHA-1-signed files or data streams they want to forge on demand, making SHA-1 an attack that is now practical in the real world, albeit at a price tag of $100,000 per collision.' -- source: https://it.slashdot.org/story/19/05/13/2255229 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/

Is It Finally the Year of 'Linux on the Desktop' ?
by Peter Reutemann 13 May '19

13 May '19

'"2019 is truly, finally shaping up to be the year of Linux on the desktop," writes PC World's senior editor, adding "Laptops, too!" But most people won't know it. That's because the bones of the open-source operating system kernel will soon be baked into Windows 10 and Chrome OS, as Microsoft and Google revealed at their respective developer conferences this week... Between lurking in Windows 10 and Chrome OS, and the tiny portion of actual Linux distro installs, pretty much any PC you pick up will run a Linux kernel and Linux software. Macs won't, but it's based on a Unix-like BSD system that already runs many Linux apps with relative ease (hence Apple's popularity with developers). You have to wonder where that leaves proper Linux distributions like Ubuntu and Linux Mint, though. They already suffer from a minuscule user share, and developers may shift toward Windows and Chrome if the Linux kernels in those operating systems get the same job done. Could this fruit wind up poisonous over the long term? We'll have to see. That said, Linux is healthier than ever. The major distros are far more polished than they used to be, with far fewer hardware woes than installs of yesteryear. You can even get your game on relatively well thanks to Valve's Proton technology, which gets many (but not all) Steam games working on Linux systems. And hey, Linux is free. Normal users may never be aware of it, but 2019 may finally be the year of Linux on the desktop -- just not Linux operating systems on the desktop.

Ubuntu 19.04: The Disco Dingo arrives and will really make your IT dept. happy
by Peter Reutemann 12 May '19

12 May '19

'Canonical recently released Ubuntu 19.04, the latest version of its flagship GNOME-based Linux desktop. But if you're a desktop user, you might be feeling a little left out. The big points of emphasis in this latest release are on Ubuntu as a tool for infrastructure development, server deployment, and the good old Internet of Things. For the server version of Ubuntu, the OS ships with all the latest cloud computing tools. In fact, that's already available in optimized builds on the major cloud services. Elsewhere, the latest version of the venerable Ubuntu desktop packs quite a few additional, tempting reasons to upgrade for Linux gamers. Ubuntu 19.04 makes the leap to the Linux kernel 5.x series, for instance, which offers much improved graphics support. Despite all the talk of developer tools and enterprise deployment stacks—Canonical has even taken to calling Ubuntu the "leading OS for cloud operations" lately—Ubuntu 19.04 is ultimately a worthwhile upgrade for all. After spending some time with it recently, we found some nice updates to the desktop, too. So no matter your Ubuntu use case, 19.04 seems to offer users a faster, more polished desktop than its predecessors.' -- source: https://arstechnica.com/gadgets/2019/05/ubuntu-19-04-review-the-disco-dingo… 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/

ImageMagick "not authorized" PDF errors
by Peter Reutemann 12 May '19

12 May '19

Hi there I was trying to convert some images into PDFs using ImageMagick's "convert" tool and encountered a "not authorized" error, something similar to the following: convert-im6.q16: not authorized `scan.pdf' @ error/constitute.c/WriteImage/1037. Took me a while figuring that one out. As it turns out, this is due to ImageMagick's security policy being tightened up (no default rights for PDF/PS): /etc/ImageMagick-6/policy.xml You can, of course, re-enable support for PDF/PS.

Firefox 66.0.3 disabled all your plugins?
by Peter Reutemann 11 May '19

11 May '19

Hi there I just updated my Firefox to 66.0.3 and all of a sudden, all my installed plugins were disabled (eg uBlock). Turns out that the release was buggy and they are working on a fix. In the meantime, you can get things going again through a trick: by enabling "participating in studies" you can get access to their hotfix to remedy this problem (though it can take some time before you get notified once you enabled this option - up to 6 hours; it only took a minute for me). For more information, see the official blog post: https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-fire… If you haven't updated to 66.0.3, then I'd strongly advice to wait for the next version to become available.

New Intel Firmware Boot Verification Bypass Enables Low-Level Backdoors
by Peter Reutemann 11 May '19

11 May '19

'At the Hack in the Box conference in Amsterdam this week, researchers Peter Bosch and Trammell Hudson presented a new attack against the Boot Guard feature of Intel's reference UEFI implementation, known as Tianocore. The attack, which can give an attacker full, persistent access, involves replacing a PC's SPI flash chip with one that contains rogue code, reports Lucian Constantin for CSO. "Even though such physical attacks require a targeted approach and will never be a widespread threat, they can pose a serious risk to businesses and users who have access to valuable information," writes Constantin. Intel has patches available for Tianocore, but as we all remember from the Meltdown and Spectre vulnerabilities, distributing UEFI patches isn't an easy process.' -- source: https://it.slashdot.org/story/19/05/10/2335225 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 Is Starting To Reveal the Secrets of Its Experimental Fuchsia OS
by Peter Reutemann 10 May '19

10 May '19

'At Google's I/O developer conference this past week, Android and Chrome chief Hiroshi Lockheimer offered some rare insight into Fuchsia, albeit at a very high level, in front of public audiences. The Verge reports: What we do know about Fuchsia is that it's an open source project, similar to AOSP, but could run all manner of devices, from smart home gadgets to laptops to phones. It's also known to be built on an all-new, Google-built kernel called "zircon," formerly known as "magenta," and not the Linux kernel that forms the foundation of Android and Chrome OS. "We're looking at what a new take on an operating system could be like. And so I know out there people are getting pretty excited saying, 'Oh this is the new Android,' or, 'This is the new Chrome OS,'" Lockheimer said. "Fuchsia is really not about that. Fuchsia is about just pushing the state of the art in terms of operating systems and things that we learn from Fuchsia we can incorporate into other products." He says the point of the experimental OS is to also experiment with different form factors, a hint toward the possibility that Fuchsia is designed to run on smart home devices, wearables, or possibly even augmented or virtual reality devices. "You know Android works really well on phones and and you know in the context of Chrome OS as a runtime for apps there. But Fuchsia may be optimized for certain other form factors as well. So we're experimenting." Lockheimer provided some additional details at a separate Android fireside chat held at Google I/O today. "It's not just phones and PCs. In the world of [the Internet of Things], there are increasing number of devices that require operating systems and new runtimes and so on. I think there's a lot of room for multiple operating systems with different strengths and specializations. Fuchsia is one of those things and so, stay tuned," he told the audience.' -- source: https://mobile.slashdot.org/story/19/05/10/0021243 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/

Open source bug poses threat to sites running multiple CMSes
by Peter Reutemann 09 May '19

09 May '19

'Websites running the Drupal, Joomla, or Typo3 content-management systems are vulnerable to attacks that could possibly execute malicious code until administrators install just-released patches, developers and security researchers warned. The vulnerability resides in the PharStreamWrapper, a PHP component developed and open-sourced by CMS maker Typo3. Indexed as CVE-2019-11831, the flaw stems from a path-traversal bug that allows hackers to swap a site's legitimate phar archive with a malicious one. A phar archive is used to distribute a complete PHP application or library in a single file, in much the way a Java archive file bundles many Java files into a single file.' -- source: https://arstechnica.com/information-technology/2019/05/open-source-bug-pose… 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/

WordPress Finally Gets the Security Features a Third of the Internet Deserves
by Peter Reutemann 08 May '19

08 May '19

' The WordPress content management system (CMS) is set to receive an assortment of new security features today that will finally add the protection level that many of its users have desired for years. From a report: These features are expected to land with the official release of WordPress 5.2, expected for later today. Included are support for cryptographically-signed updates, support for a modern cryptography library, a Site Health section in the admin panel backend, and a feature that will act as a White-Screen-of-Death (WSOD) protection -- letting site admins access their backend in the case of catastrophic PHP errors. With WordPress being installed on around 33.8 percent of all internet sites, these features are set to put some fears at ease in regards to some attack vectors. Probably the biggest and the most important of today's new security features is WordPress' offline digital signatures system. Starting with WordPress 5.2, the WordPress team will digitally sign its update packages with the Ed25519 public-key signature system so that a local installation will be able to verify the update package's authenticity before applying it to a local site.' -- source: https://it.slashdot.org/story/19/05/07/1930208 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 Q Gets Dark Mode, Live Video Captioning, Better Gestures and More
by Peter Reutemann 07 May '19

07 May '19

'At its annual I/O developer event, Google announced a bunch of new features available in the latest Android Q beta. Engadget reports: The most obvious new feature is dark mode, which will be released system-wide in Android Q. It's accessible via a toggle switch in the quick settings area and it'll also be activated when you turn on battery saver mode. We just saw a quick screenshot of it, but it looks like it'll apply to any apps you're using regardless of whether they're Google-made or from other developers. Another notable new feature is called Live Caption. If you're watching a video, Google's machine-learning algorithms can now add captions on the fly by just pressing the volume button and then a "live caption" button that'll show up on on the onscreen volume slider. From there, you can expand and contract the panel as you see fit, and move it up and down on the screen so it doesn't obscure your video. Google is also able to do all of this on-device, so it's more secure and also doesn't need a network connection. [T]he company says that there are 50 new privacy and security settings in Android Q. Perhaps most notable are new location services settings that let you limit location tracking to only when the app is running. It'll also give you notifications to let users see when apps are using your location in the background. New settings also let you keep apps from accessing media on your phone and collecting information about your device like its IMEI and serial number. [...] Google's adding a new "focus mode" to help shut down various distractions. It'll block most app alerts and notifications while allowing important contacts like your family members to reach you. There are also more tools for parents to manage their kids' phone time -- it'll let you review how they're using their phone from your own device, set daily time limits, review app requests and more. There are also tweaks to the gesture-based navigation bar to make it more closely resemble the navigation gestures first introduced in the iPhone X. Google's also adding a new chat-focused interface called "bubbles" that lets users keep messaging conversations accessible regardless of what they're doing with the phone. We can expect the final desert-themed name and release date later in the summer.

Cray, AMD to build 1.5 exaflops supercomputer for US government
by Peter Reutemann 07 May '19

07 May '19

'AMD and Cray have announced that they're building "Frontier," a new supercomputer for the Department of Energy at Oak Ridge National Laboratory. The goal is to deliver a system that can perform 1.5 exaflops: 1.5×1018 floating point operations per second. By way of comparison, a single Nvidia RTX 2080 GPU manages about 14 teraflops of compute performance with 32-bit numbers. Frontier will achieve 100,000 times more. The fastest supercomputer in the Top 500 list weighs in at 200 petaflops, or 0.2 exaflops. As things stand, it'd take the top 160 machines on the list to match Frontier's performance. Frontier will use custom versions of AMD's Epyc processors (likely Zen 3 or Zen 4), matched with 4 GPUs, all connected using AMD's Infinity Fabric. Between nodes, Cray's Slingshot interconnect will be used, which has transfer rates of up to 200Gb/s per port. The GPUs will have their own stacked HBM (High Bandwidth Memory). It'll be housed in 100 cabinets, taking about 7,300 square feet of floor space. Power consumption will be 30-40MW. The plan is for Frontier to be delivered in 2021, at a cost of about $500 million for the hardware and $100 million for research and development. It should be the fastest supercomputer in the world when it's delivered, and it will be the US government's second exaflops-capable system; the first will be the 1 exaflops Aurora, built using Intel Xeon SP processors and Intel Xe GPUs.' -- source: https://arstechnica.com/gadgets/2019/05/cray-amd-to-build-1-5-exaflops-supe… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Windows 10 will soon ship with a full, open source, GPLed Linux kernel
by Peter Reutemann 06 May '19

06 May '19

'Earlier today, we wrote that Microsoft was going to add some big new features to the Windows Subsystem for Linux, including native support for Docker containers. It turns out that that ain't the half of it. The current Windows Subsystem for Linux uses a Microsoft-authored kernel component that provided the same kernel API as the Linux kernel but written from scratch by Microsoft. Essentially, it translated from Linux APIs to Windows NT kernel APIs. That worked pretty well, but the current subsystem had a few shortcomings: there was no ability to use Linux drivers, in particular file system drivers. Its file system performance, layered on top of Windows' own NTFS, was often 20 times slower than a real Linux kernel. It was also a relatively old version of the kernel; it offered approximately the set of APIs that Linux 4.4 did, and that was released in 2016. Some APIs aren't implemented at all, and others are only partially implemented to meet the needs of specific applications. All is changing with Windows Subsystem for Linux 2. Instead of emulating the Linux kernel APIs on the NT kernel, WSL 2 is going to run a full Linux kernel in a lightweight virtual machine. This kernel will be trimmed down and tailored to this particular use case, with stripped-down hardware support (since it will defer to the host Windows OS for that) and faster booting.' -- source: https://arstechnica.com/gadgets/2019/05/windows-10-will-soon-ship-with-a-fu… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Does Open Source Have a 'Working For Free' Problem?
by Peter Reutemann 05 May '19

05 May '19

'"Let's abandon the notion that open source is exclusively charity," writes Havoc Pennington, a free software engineer (and former Red Hat engineer) who's now a co-founder of Tidelift: Look around. We do have a problem, and it's time we do something about it.... The lack of compensation isn't just bad for individual developers -- it also creates social problems, by amplifying existing privilege.... The narrative around open source is that it's completely OK -- even an expectation -- that we're all doing this for fun and exposure; and that giant companies should get huge publicity credit for throwing peanuts-to-them donations at a small subset of open source projects. There's nothing wrong with doing stuff for fun and exposure, or making donations, as an option. It becomes a problem when the free work is expected and the donations are seen as enough... What would open source be like if we had a professional class of independent maintainers, constantly improving the code we all rely on? The essay suggests some things consider, including asking people to pay for: * Support requests * Security audits/hardening and extremely good test coverage * Supporting old releases * License-metadata-annotation practices that are helpful for big companies trying to audit the code they use, but sort of a pain in the ass and nobody cares other than these big companies. "Right now many users expect, and demand, that all of this will be free. As an industry, perhaps we should push back harder on that expectation. It's OK to set some boundaries..." "Of course this relates to what we do at Tidelift -- the company came out of discussions about this problem, among others... In our day-to-day right now we're specifically striving to give subscribers a way to pay maintainers of their application dependencies for additional value, through the Tidelift Subscription. But we hope to see many more efforts and discussions in this area.... [I]n between a virtual tip jar and $100 million in funding, there's a vast solution space to explore."' -- source: https://news.slashdot.org/story/19/04/28/0459236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hard Drive Reliability At Backblaze
by Lawrence D'Oliveiro 05 May '19

05 May '19

This article <https://www.theregister.co.uk/2019/05/03/backblaze_drive_reliability_stats/> on the latest disk reliability report from backup business Backblaze led me to following up some interesting links. In this older item <https://www.theregister.co.uk/2014/02/17/backblaze_how_not_to_evaluate_disk…>, they were criticized for making misleading claims about consumer-grade drives being more reliable than enterprise-grade ones. But I do think it is clear that the difference between them is not worth the cost. One important point I got from the latter is “replacing one drive takes about 15 minutes of work”. That quote ends with “Moral of the story: design for failure and buy the cheapest components you can”. Which seems the logical thing to do anyway. That sentence is followed by a smiley, but as far as I’m concerned, who needs the smiley? I also like this article <https://www.backblaze.com/blog/hard-drive-smart-stats/> from their blog, where they go into which SMART statistics are worth looking at. The one that stands out is counter 187, uncorrectable read errors. If that goes above zero, then the disk is bad and should be replaced.

Security Lapse Exposed a Chinese Smart City Surveillance System
by Peter Reutemann 04 May '19

04 May '19

'Smart cities are designed to make life easier for their residents: better traffic management by clearing routes, making sure the public transport is running on time and having cameras keeping a watchful eye from above. But what happens when that data leaks? One such database was open for weeks for anyone to look inside. Security researcher John Wethington found a smart city database accessible from a web browser without a password. He passed details of the database to TechCrunch in an effort to get the data secured. The database was an Elasticsearch database, storing gigabytes of data -- including facial recognition scans on hundreds of people over several months. The data was hosted by Chinese tech giant Alibaba. The customer, which Alibaba did not name, tapped into the tech giant's artificial intelligence-powered cloud platform, known as City Brain. "This is a database project created by a customer and hosted on the Alibaba Cloud platform," said an Alibaba spokesperson. "Customers are always advised to protect their data by setting a secure password." "We have already informed the customer about this incident so they can immediately address the issue. As a public cloud provider, we do not have the right to access the content in the customer database," the spokesperson added. The database was pulled offline shortly after TechCrunch reached out to Alibaba. But while Alibaba may not have visibility into the system, we did.' -- source: https://yro.slashdot.org/story/19/05/04/0235239 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 Proposes 'Do-Not-Track Act of 2019'
by Peter Reutemann 04 May '19

04 May '19

'"When you turn on the setting in your browser that says 'Do Not Track', you probably expect to no longer be tracked on most websites you visit. Right? Well, you would be wrong," explains DuckDuckGo's blog. Their recent study found "a quarter of people have turned on this setting" -- representing hundreds of millions of web surfers -- and that most of them were unaware that in fact, "no law requires websites to respect your Do Not Track signals, and the vast majority of sites, including most all of the big tech companies, sadly choose to simply ignore them." Now they've written draft legislation -- "the Do-Not-Track Act of 2019" -- to "serve as a starting point" for legislators to close this loophole. SearchEngineLand reports: If the act picks up steam and passes into law, sites would be required to cease certain user tracking methods, which means less data available to inform marketing and advertising campaigns. The impact could also cascade into platforms that leverage consumer data, possibly making them less effective. For example, one of the advantages of advertising on a platform like Google or Facebook is the ability to target audiences. If a user enables DNT, the ads displayed to them when browsing those websites won't be informed by their external browsing history... This proposal is quite far from being signed into law, but the technology is already built into Chrome, Firefox, Opera, Edge and Internet Explorer. With the adoption of GDPR just a year behind us and presidential candidate Elizabeth Warren's proposed legislation to regulate "big tech companies" drawing more attention to digital privacy issues in Washington, the Do-Not-Track Act could be a realistic outcome. DuckDuckGo says they're announcing their draft legislation because "It is extremely rare to have such an exciting legislative opportunity like this, where the hardest work -- coordinated mainstream technical implementation and widespread consumer adoption -- is already done.... "We hope the Do-Not-Track Act of 2019 serves as a useful guide to start thinking seriously about this amazing legislative opportunity."' -- source: https://yro.slashdot.org/story/19/05/03/2316223 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/

Don’t Try To Claim That Public Wi-Fi Is “Inherently Insecure”

NordVPN has been told off by the UK Advertising Standards Authority about its misleading claims on the security of public wi-fi <https://www.theregister.co.uk/2019/05/01/nordvpn_tv_ad_rapped_advertising_s…>: Justifying its claims, NordVPN told the ASA that HTTPS encryption of webpages "did not mean the site was legitimate, nor was it any proof that the site had been security-hardened against intrusion from hackers". Yes, HTTPS encryption *is* supposed to mean that the site is legitimate. As for whether the site is security-hardened, it’s going to be just as insecure whether you access it via a VPN or not, isn’t it?

Putin Signs Law To Create an Independent Russian Internet
by Peter Reutemann 02 May '19

02 May '19

'Russia is one step closer to creating its own, independent internet -- at least legally speaking. Russian President Vladimir Putin has signed into law new measures that would enable the creation of a national network, able to operate separately from the rest of the world, according to documents posted on a government portal this week. >From a report: For now, the network remains largely theoretical though, with few practical details disclosed. In concept, the new law aims to protect Russia from foreign online restrictions by creating what the Kremlin calls a "sustainable, secure and fully functioning" local internet. The legislation takes effect in November, state news agency RIA-Novosti reported. According to a summary from RIA-Novosti, the law calls for the creation of a monitoring and a management center supervised by Roskomnadzor, Russia's telecoms agency. The state agency will be charged with ensuring the availability of communication services in Russia in extraordinary situations. During such situations, it would also be empowered to cut off external traffic exchange, creating a purely Russian web' -- source: https://tech.slashdot.org/story/19/05/02/1535237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Says It Will Ban Firefox Add-ons With Obfuscated Code
by Peter Reutemann 02 May '19

02 May '19

'As Mozilla continues to try to make it safer than ever to use Firefox, the organization has updated its Add-on Policy so that any updates that include obfuscated code are explicitly banned. Mozilla has also set out in plain terms its blocking process for add-ons and extensions. While there is nothing surprising here, the clarification should mean that there are fewer causes for disputes when an add-on is blocklisted. The updated Add-on policy comes into force on June 10, so add-on developers have a little more than a month to take note of the changes and comply. Mozilla says that the move is designed to help it better deal with malicious extensions. Mozilla also plans to be more aggressive towards taking down extensions that break its policies, with a heavy focus on security issues. ZDNet adds: [...] Starting with June 10, Mozilla's team will also be more aggressive in blocking and disabling Firefox add-ons in users' browsers that are found to be violating one of the company's policies."We will continue to block extensions for intentionally violating our policies, critical security vulnerabilities, and will also act on extensions compromising user privacy or circumventing user consent or control," Nieman said.' -- source: https://news.slashdot.org/story/19/05/02/1653228 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/

In other words, this is a significant operating system upgrade that should delight both existing Fedora users and beginners alike. "Fedora 30 brings enhancements to all editions with updates to the common underlying packages, from bug fixes and performance tweaks to new versions. In Fedora 30, base updates include Bash shell 5.0, Fish 3.0, the GNU Compiler Collection (GCC) 9 and Ruby 2.6. Fedora 30 also now uses the zchunk format for data compression within the DNF repository. When metadata is compressed using zchunk DNF will only download the differences between earlier copies of metadata and the current versions, saving on resources and increasing efficiency," says The Fedora Project.' -- source: https://linux.slashdot.org/story/19/04/30/1742231 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 an Obsolete Medical Device With a Security Flaw Became a Must-Have For Some Patients With Type 1 Diabetes
by Peter Reutemann 30 Apr '19

30 Apr '19

'In 2014, a few hackers realized that the security flaw in certain Medtronic pumps could be exploited for a DIY revolution. Type 1 diabetes is a disease where the pancreas is unable to produce insulin to control blood sugar. For years, Boss (the anecdote in the story who purchased used insulin pumps from some dealer on Craiglist) had counted, down to the gram, the carbohydrates in every meal and told his pump how much insulin to dispense. [...] By 2014, the hardware components of a DIY artificial pancreas -- a small insulin pump that attaches via thin disposable tubing to the body and a continuous sensor for glucose, or sugar, that slips just under the skin -- were available, but it was impossible to connect the two. That's where the security flaw came in. The hackers realized they could use it to override old Medtronic pumps with their own algorithm that automatically calculates insulin doses based on real-time glucose data. It closed the feedback loop. They shared this code online as OpenAPS, and "looping," as it's called, began to catch on. Instead of micromanaging their blood sugar, people with diabetes could offload that work to an algorithm. In addition to OpenAPS, another system called Loop is now available. Dozens, then hundreds, and now thousands of people are experimenting with DIY artificial-pancreas systems -- none of which the Food and Drug Administration has officially approved. And they've had to track down discontinued Medtronic pumps. It can sometimes take months to find one. Obviously, you can't just call up Medtronic to order a discontinued pump with a security flaw. "It's eBay, Craigslist, Facebook. It's like this underground market for these pumps," says Aaron Kowalski, a DIY looper and also CEO of JDRF, a nonprofit that funds type 1 diabetes research. This is not exactly how a market for lifesaving medical devices is supposed to work. And yet, this is the only way it can work -- for now.' -- source: https://science.slashdot.org/story/19/04/29/2051257 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/

Finally ... The Vertical TV
by Lawrence D'Oliveiro 29 Apr '19

29 Apr '19

I’ve been wondering when this was going to happen. Just as widescreen TVs and computer monitors have become standard, more and more video footage is being shared, whether on broadcast TV, social media or whatever, that was captured on mobile phones in *portrait* mode. So you get the awkward problem of filling in the gaps on the sides of the screen with something useless but unobtrusive (heavily-blurred portions of the actual content seems popular right now), and wasting all that display resolution to boot. Seems like going back to 4:3 monitors, or even an orientation-neutral square 1:1 shape, is not an option. But Samsung has the solution: a TV that can rotate to portrait mode! <https://arstechnica.com/gadgets/2019/04/samsung-embraces-vertical-videos-wi…>

The Mysterious History of the MIT License
by Peter Reutemann 28 Apr '19

28 Apr '19

'Red Hat technology evangelist Gordon Haff explains why it's hard to say exactly when the MIT license created. Citing input from both Jim Gettys (author of the original X Window System) and Keith Packard (a senior member on the X Windows team), he writes that "The best single answer is probably 1987. But the complete story is more complicated and even a little mysterious."' -- source: https://news.slashdot.org/story/19/04/28/0326207 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 the Boeing 737 Max Disaster Looks to a Software Developer
by Lawrence D'Oliveiro 27 Apr '19

27 Apr '19

The author of this article <https://spectrum.ieee.org/aerospace/aviation/how-the-boeing-737-max-disaste…> (archive.org copy at <https://web.archive.org/web/20190418200057/https://spectrum.ieee.org/aerosp…>) is both a pilot and a software developer. He looks into the root causes of the Boeing 737 MAX crashes in Indonesia and Ethiopia. Basic points: * The new aircraft has sufficiently different airframe handling characteristics to be classified as a new model. * Boeing didn’t want it to be treated as a new model, because of the extra regulatory costs, pilot training etc this would entail. * So they implemented software (“MCAS”) that actively managed the handling characteristics to make it behave to pilots like previous 737 models. * They neglected to tell the pilots about the software. * It also turns out that correct operation of this software depends on a hardware component that is known to be unreliable.

Vodafone’s “Free E-Mail Forwarding For Life” Comes To End Of Life
by Lawrence D'Oliveiro 26 Apr '19

When Vodafone shut down its e-mail services in 2017, it promised to continue autoforwarding e-mail to customers’ new addresses indefinitely. Well, now that “indefinitely” is coming to a definite end. It is just becoming too hard to maintain the service, particularly when other e-mail services start treating such auto-forwarded messages as spam or blocking them altogether. <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=122233…>

When Is Hate Speech Not Hate Speech?

Is it “hate speech” to tell NRA supporters to “f*** off”? One high-profile user got banned (supposedly permanently) by Twitter for doing this sort of thing ... only to have the ban reversed, simply because there was so much support for his position. Seems like, when it comes to social media services clamping down on hate speech, they are simultaneously doing “not enough” and “too much”... <https://www.techdirt.com/articles/20190421/16313642055/twitter-permanently-…>

Copies Of Mueller Report Taken Down Because Of ... Copyright Infringement?
by Lawrence D'Oliveiro 23 Apr '19

23 Apr '19

For those pushing for mandatory copyright filtering, here’s yet another cautionary tale: copies of the (redacted) Mueller Report were taken down from PDF-hosting site Scribd, even though it is in the public domain. It seems clear this was an inadvertent result of automatic filtering policies; one of the many big-name publishers who had put out for-sale copies of the report had used automated processes to pass the information to Scribd, and these processes had blocked everybody’s attempts to upload copies of the report, even though it didn’t own the copyright. <https://www.techdirt.com/articles/20190420/23233942052/scribds-takedown-pub…>

Streaming TV Has Become An Expensive, Complicated Mess
by Lawrence D'Oliveiro 22 Apr '19

22 Apr '19

<https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=122224…>: But this entertainment nirvana never actually arrived. First came pricey broadband services required to stream Internet video, often delivered by the same cable wires consumers longed to cut. Then came a proliferation of services - offered by Netflix, Amazon, Hulu plus and more - each with a bill of its own. Then came more boxes, wires and remotes. And finally came the question: How exactly do I get my Star Wars fix? Maybe a bit US-centric, but I think that also reflects the situation for streaming here as well. The article talks about “cord-cutting” -- as you may know, most people in the US have been watching conventional TV stations through cable connections, not through broadcasts. “Cord-cutting” is the increasing tendency of customers to terminate their cable TV accounts. But those same cable companies are also ISPs, and given the limitations on competition between ISPs in the US (thanks to the current regime’s allergy to enforcing meaningful net-neutrality legislation), those same companies will get the money from customers wanting to watch streaming video.

DARPA Wants To Make a Better, More Secure Version of WhatsApp
by Peter Reutemann 15 Apr '19

15 Apr '19

'The Defense and Advanced Research Projects Agency (DARPA) appears to be in the process of developing its own ultra secure communication platform. The program is called "Resilient Anonymous Communication for Everyone," or RACE, and it will be similar to WhatsApp in that it will be for everyone to use. Trusted Reviews reports: The objectives of the program are to create a distributed messaging system that can do three things: Exist completely within a network; Provide confidentiality, integrity and availability of messaging; and Preserve privacy to any participant in the system. DARPA seem to be putting security front and center, and the description of the project claims that "compromised system data and associated networked communications should not be helpful for comprising any additional parts of the system," meaning that DARPA are keen that one breach shouldn't also give them a leg up on access to other parts of the system. So, will we soon be using a U.S government branded DARPA? Probably not, but the chances are that RACE will go some way to creating a messaging app that's resilient to attacks, with the protocol and security they find no doubt dripping through to consumer tech and features in the coming years.

But the issue is much worse than previously reported, with the hackers able to access email content from a large number of Outlook, MSN, and Hotmail email accounts, according to a source who witnessed the attack in action and described it before Microsoft's statement, as well as screenshots provided to Motherboard.

Former Firefox VP on What It's Like To Be Both a Partner of Google and a Competitor via Google Chrome
by Peter Reutemann 15 Apr '19

15 Apr '19

'Sidewalk Labs, the urban innovation arm of Google's parent company Alphabet, plans to build a $1 billion high-tech neighborhood in Toronto. The problem? It is facing an opposition from residents who have called for its demise. As the backlash gains momentum, it could force Sidewalk Labs to abandon or alter its vision. On paper, Sidewalk Labs' idea arguably has some merits: It wishes to "set new standards" for how cities are designed and built. But some are apprehensive of Google's plans, because the company has a knack for assuming more control over things and killing local competition. Johnathan Nightingale, a former VP of Firefox, has seen such behavior first hand. He draws some parallels: I spent 8 years at Mozilla working on Firefox and for almost all of that time Google was our biggest partner. Our revenue share deal on search drove 90% of Mozilla's income. When I started at Mozilla in 2007, there was no Google Chrome and most folks we spoke with inside were Firefox fans. They were building an empire on the web, we were building the web itself. I think our friends inside Google genuinely believed that. At the individual level, their engineers cared about most of the same things we did. Their product and design folks made many decisions very similarly and we learned from watching each other. But Google as a whole is very different than individual Googlers. Google Chrome ads started appearing next to Firefox search terms. Gmail and Google Docs started to experience selective performance issues and bugs on Firefox. Demo sites would falsely block Firefox as "incompatible." All of this is stuff you're allowed to do to compete, of course. But we were still a search partner, so we'd say "hey what gives?" And every time, they'd say, "oops. That was accidental. We'll fix it in the next push in 2 weeks." Over and over. Oops. Another accident. We'll fix it soon. We want the same things. We're on the same team. There were dozens of oopses. Hundreds maybe? I'm all for "don't attribute to malice what can be explained by incompetence" but I don't believe Google is that incompetent. This is not a thread about blaming Google for Firefox troubles though. We at Mozilla wear that ourselves, me more than anyone for my time as Firefox VP. But I see the same play happening here in my city and I don't like it. And for me it means two things: 1. The question is not whether individual Sidewalk Labs people have pure motives. I know some of them, just like I know plenty on the Chrome team. They're great people. But focus on the behavior of the organism as a whole. At the macro level, Google/Alphabet is very intentional. When Google wants to get a thing done, it is very effective. Mistakes happen, but when you see a sustained pattern of "oops" and delays from this organization -- you're being outfoxed. Get there faster than I did.' -- source: https://tech.slashdot.org/story/19/04/15/0326208 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/

Is The Linux Desktop In Trouble?
by Peter Reutemann 14 Apr '19

14 Apr '19

'"I believe that, as Microsoft keeps moving Windows to a Desktop-as-a-Service model, Linux will be the last traditional PC desktop operating system standing," writes ZDNet contributing editor Steven J. Vaughan-Nichols. "But that doesn't mean I'm blind to its problems." First, even Linus Torvalds is tired of the fragmentation in the Linux desktop. In a recent [December 2018] TFiR interview with Swapnil Bhartiya, Torvalds said, "Chromebooks and Android are the path toward the desktop." Why? Because we don't have a standardized Linux desktop. For example, better Linux desktops, such as Linux Mint, provide an easy way to install applications, but under the surface, there are half-a-dozen different ways to install programs. That makes life harder for developers. Torvalds wishes "we were better at having a standardized desktop that goes across the distributions." Torvalds thinks there's been some progress. For software installation, he likes Flatpak. This software program, like its rival Snap, lets you install and maintain programs across different Linux distros. At the same time, this rivalry between Red Hat (which supports Flatpak) and Canonical (which backs Snap) bugs Torvalds. He's annoyed at how the "fragmentation of the different vendors have held the desktop back." None of the major Linux distributors -- Canonical, Red Hat, SUSE -- are really all that interested in supporting the Linux desktop. They all have them, but they're focused on servers, containers, the cloud, and the Internet of Things (IoT). That's, after all, is where the money is. Linux desktop distros "tend to last for five or six years and then real life gets in the way of what's almost always a volunteer effort..." the article argues. "It is not easy building and supporting a Linux desktop. It comes with a lot of wear and tear on its developers with far too little reward." His solution? Having a foundation create a common desktop for all Linux distros, so the Linux world could finally reap the benefits of standardization. "This would mean that many more Linux desktop developers could make a living from their work. That would improve the Linux desktop overall quality. "It's a virtuous cycle, which would help everyone."' -- source: https://linux.slashdot.org/story/19/04/13/0151256 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/

Internet Explorer Exploit Steals Data From Windows Users-- Even If They Never Use Internet Explorer
by Peter Reutemann 14 Apr '19

14 Apr '19

'Security researcher John Page has revealed a new zero-day exploit that allows remote attackers to exfiltrate Local files using Internet Explorer. "The craziest part: Windows users don't ever even have to open the now-obsolete web browser for malicious actors to use the exploit," reports Mashable. "It just needs to exist on their computer..." [H]ackers are taking advantage of a vulnerability using .MHT files, which is the file format used by Internet Explorer for its web archives. Current web browsers do not use the .MHT format, so when a PC user attempts to access this file Windows opens IE by default. To initiate the exploit, a user simply needs to open an attachment received by email, messenger, or other file transfer service... Most worrisome, according to Page, is that Microsoft told him that it would just "consider" a fix in a future update. The security researcher says he contacted Microsoft in March before now going public with the issue. As ZDNet points out, while Internet Explorer usage makes up less than 10 percent of the web browser market, it doesn't particularly matter in this case as the exploit just requires a user to have the browser on their PC.' -- source: https://it.slashdot.org/story/19/04/14/2232252 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Does Wi-Fi Security Really Matter?
by Lawrence D'Oliveiro 11 Apr '19

11 Apr '19

Seems the Wi-Fi Alliance is having yet another crack at coming up with a really secure protocol, this time to be called WPA3 <http://www.theregister.co.uk/2018/01/09/wi_fi_wpa3/>. Does anybody care? Remember that on the Internet, security is implemented between the endpoints, the protocols are designed not to care that everything in-between might be pawed through by eavesdroppers, or even active attackers trying to inject fake data.

Dragonblood Vulnerabilities Disclosed in Wi-Fi WPA3 Standard
by Peter Reutemann 11 Apr '19

11 Apr '19

'Two security researchers disclosed details this week about a group of vulnerabilities collectively referred to as Dragonblood that impact the Wi-Fi Alliance's recently launched WPA3 Wi-Fi security and authentication standard. From a report: If ever exploited, the vulnerabilities would allow an attacker within the range of a victim's network to recover the Wi-Fi password and infiltrate the target's network. In total, five vulnerabilities are part of the Dragonblood ensemble -- a denial of service attack, two downgrade attacks, and two side-channel information leaks. While the denial of service attack is somewhat unimportant as it only leads to crashing WPA3-compatible access points, the other four are the ones that can be used to recover user passwords. Both the two downgrade attacks and two side-channel leaks exploit design flaws in the WPA3 standard's Dragonfly key exchange -- the mechanism through which clients authenticate on a WPA3 router or access point. In a downgrade attack, Wi-Fi WPA3-capable networks can be coerced in using an older and more insecure password exchange systems, which can allow attackers to retrieve the network passwords using older flaws.' -- source: https://mobile.slashdot.org/story/19/04/11/1431219 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/

Gmail Becomes First Major Email Provider To Support MTA-STS and TLS Reporting
by Peter Reutemann 11 Apr '19

11 Apr '19

'Google announced this week that Gmail has become the first major email provider to support two new security standards, namely MTA-STS and TLS Reporting. From a report: Both are extensions to the Simple Mail Transfer Protocol (SMTP), the protocol through which all emails are sent today. The purpose of MTA-STS and TLS Reporting is to help email providers establish cryptographically secure connections between each other, with the main goal of twarthing SMTP man-in-the-middle attacks. SMTP man-in-the-middle attacks are a major problem for today's email landscape, where rogue email server operators can intercept, read, and modify the contents of people's emails. The two new standards will prevent this by allowing legitimate email providers to create a secure channel for exchanging emails.' -- source: https://tech.slashdot.org/story/19/04/11/1822228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Amazon Workers Are Listening To What You Tell Alexa
by Peter Reutemann 11 Apr '19

11 Apr '19

'Amazon reportedly employs thousands of people around the world to help improve its Alexa digital assistant. "The team listens to voice recordings captured in Echo owners' homes and offices," reports Bloomberg. "The recordings are transcribed, annotated and then fed back into the software as part of an effort to eliminate gaps in Alexa's understanding of human speech and help it better respond to commands." From the report: The team comprises a mix of contractors and full-time Amazon employees who work in outposts from Boston to Costa Rica, India and Romania, according to the people, who signed nondisclosure agreements barring them from speaking publicly about the program. They work nine hours a day, with each reviewer parsing as many as 1,000 audio clips per shift, according to two workers based at Amazon's Bucharest office, which takes up the top three floors of the Globalworth building in the Romanian capital's up-and-coming Pipera district. The modern facility stands out amid the crumbling infrastructure and bears no exterior sign advertising Amazon's presence. The work is mostly mundane. One worker in Boston said he mined accumulated voice data for specific utterances such as "Taylor Swift" and annotated them to indicate the searcher meant the musical artist. Occasionally the listeners pick up things Echo owners likely would rather stay private: a woman singing badly off key in the shower, say, or a child screaming for help. The teams use internal chat rooms to share files when they need help parsing a muddled word -- or come across an amusing recording. Sometimes they hear recordings they find upsetting, or possibly criminal. Two of the workers said they picked up what they believe was a sexual assault. When something like that happens, they may share the experience in the internal chat room as a way of relieving stress. Amazon says it has procedures in place for workers to follow when they hear something distressing, but two Romania-based employees said that, after requesting guidance for such cases, they were told it wasn't Amazon's job to interfere. [...] Amazon, in its marketing and privacy policy materials, doesn't explicitly say humans are listening to recordings of some conversations picked up by Alexa. "We use your requests to Alexa to train our speech recognition and natural language understanding systems," the company says in a list of frequently asked questions. In Alexa's privacy settings, the company gives users the option of disabling the use of their voice recordings for the development of new features. A screenshot reviewed by Bloomberg shows that the recordings sent to the Alexa auditors don't provide a user's full name and address but are associated with an account number, as well as the user's first name and the device's serial number. An Amazon spokesperson said in a statement to Bloomberg: "We take the security and privacy of our customers' personal information seriously. We only annotate an extremely small sample of Alexa voice recordings in order [to] improve the customer experience. For example, this information helps us train our speech recognition and natural language understanding systems, so Alexa can better understand your requests, and ensure the service works well for everyone." They added: "We have strict technical and operational safeguards, and have a zero tolerance policy for the abuse of our system. Employees do not have direct access to information that can identify the person or account as part of this workflow. All information is treated with high confidentiality and we use multi-factor authentication to restrict access, service encryption and audits of our control environment to protect it."' -- source: https://yro.slashdot.org/story/19/04/10/2340251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

You Can Now Use Your Android Phone as a 2FA Security Key for Google Accounts
by Peter Reutemann 10 Apr '19

10 Apr '19

'Google said today it will now enable Android users to use their smartphones as a Fast Identity Online (FIDO) security key (for two-step authentication) for their Google accounts, thereby addressing one of the biggest challenges that has slowed the adoption of this security measure: convenience. A report adds: You can thus use your Android phone to protect your personal Google account, and your G Suite, Cloud Identity, and Google Cloud Platform work accounts. (Android tablets aren't supported -- Google specifically limited the functionality since users are more likely to have phones with them.) This means Android phones can move from two-step verification (2SV) to two-factor authentication (2FA). 2SV is a method of confirming a user's identity using something they know (password) and a second thing they know (a code sent via text message). 2FA is a method of confirming a user's identity by using a combination of two different factors: something they know (password), something they have (security key), or something they are (fingerprint). The feature is coming only to Android devices versions 7 and up.' -- source: https://tech.slashdot.org/story/19/04/10/1621253 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 Chrome Wants To Block Some HTTP File Downloads

The plan is to block EXE, DMG, CRX, ZIP, GZIP, BZIP, TAR, RAR, and 7Z file downloads when the download is initiated via HTTP but the website URL shows HTTPS. Google said it's currently not thinking of blocking all downloads started from HTTP sites, since the browser already warns users about a site's poor security via the "Not Secure" indicator in the URL bar.

Mysterious safety-tampering malware infects a second critical infrastructure site
by Peter Reutemann 10 Apr '19

10 Apr '19

'Sixteen months ago, researchers reported an unsettling escalation in hacks targeting power plants, gas refineries, and other types of critical infrastructure. Attackers who may have been working on behalf of a nation caused an operational outage at a critical-infrastructure site after deliberately targeting a system that prevented health- and life-threatening accidents. Game-changing attack on critical infrastructure site causes outage There had been compromises of critical infrastructure sites before. What was unprecedented in this attack—and of considerable concern to some researchers and critical infrastructure operators—was the use of an advanced piece of malware that targeted the unidentified site’s safety processes. Such safety instrumented systems (SIS) are a combination of hardware and software that many critical infrastructure sites use to prevent unsafe conditions from arising. When gas fuel pressures or reactor temperatures rise to potentially unsafe thresholds, for instance, a SIS will automatically close valves or initiate cooling processes to prevent health- or life-threatening accidents. Russia was likely behind dangerous critical infrastructure attack, report says By focusing on the site’s SIS, the malware carried the threat of physical destruction that depending on the site and the type of accident had the potential to be serious if not catastrophic. The malware was alternately named Triton and Trisis, because it targeted the Triconex product line made by Schneider Electric. It’s development was ultimately linked to a Russian government-backed research institute.' -- source: https://arstechnica.com/information-technology/2019/04/mysterious-safety-ta… 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/

Despite the nominal end of support for Windows XP five years ago, the existence of POSReady 2009 allowed users to receive security updates on Windows XP Home and Professional SP3 through the use of a registry hack. Microsoft dissuaded users from doing this, stating that they "do not fully protect Windows XP customers," though no attempt was apparently made to prevent users from using this hack. With POSReady reaching the end of support, the flow of these security updates will likewise come to an end.' -- source: https://tech.slashdot.org/story/19/04/10/0017208 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 Most Public Windows Error-Message Screen Ever?
by Lawrence D'Oliveiro 09 Apr '19

09 Apr '19

There has long been a history of Windows error messages popping up in the most embarrassing public places, like on status displays in train stations, shopping malls and the like. Could this example be some kind of record for being the most public? Being wrapped right round the top of one of the tallest buildings in London, after all. <https://www.theregister.co.uk/2019/04/08/bt_tower_broadcasts_error_message_…>

Hi everyone Due to Easter falling on our usual WLUG meeting slot on the 22nd and the university no longer allowing rooms to be used on public holidays, this month's meeting will happen next Monday, a week earlier. At this stage, I'm still looking for a speaker. A talk on Wayland was suggested, but I never received a confirmation/blurb, unfortunately. https://www.meetup.com/WaikatoLinuxUsersGroup/events/257884273/ 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/

Opera Adds Crypto Wallet To Its Desktop Browser, Launches Anti-Chrome Campaign in Europe
by Peter Reutemann 09 Apr '19

09 Apr '19

'Opera has updated its eponymous web browser for the desktop with a crypto-makeover and a number of additional features. From a report: The Norway-headquartered browser maker has also launched a marketing campaign to cash in on the EU regulatory order that requires Google to give Android users in Europe more options to choose their preferred browser. Dubbed 'Reborn 3,' the latest version of Opera for Windows, macOS, and Linux includes a native cryptocurrency wallet, which follows Opera's Android app getting this feature in December. The wallet keys and transactions are synced between the desktop and mobile browsers with the latter also serving as a way for the user to authenticate their identity, the company said. [...] Additionally, Opera is speeding up the free VPN feature, after adding this feature to its Android app last month.' -- source: https://tech.slashdot.org/story/19/04/09/1356246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla is Launching Curated Recommended Extensions Program This Summer
by Peter Reutemann 09 Apr '19

'However much you love your chosen web browser, you have probably enhanced its capabilities through the use of add-ons. Finding decent, reliable add-ons can be tricky, and this is why Mozilla is launching the Recommended Extensions program. This editor-curated program will surface the very best vetted extensions for Firefox, and it is due to roll out in stages later this summer. Mozilla says that any extensions it recommends through the program will be highlighted across its portfolio of websites and products, including addons.mozilla.org (AMO) and on Firefox's Get Add-Ons page. The company is already identifying extensions it likes the look of, and will soon be reaching out to developers. Changes should be seen on AMO around June.' -- source: https://tech.slashdot.org/story/19/04/09/1444248 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/

Several Major Browsers to Prevent Disabling of Click-Tracking 'Hyperlink Auditing'
by Peter Reutemann 08 Apr '19

08 Apr '19

'A HTML standard called hyperlink auditing that allows sites to track link clicks is enabled by default on Safari, Chrome, Opera, and Microsoft Edge, but will soon have no way to disable it. As it is considered a privacy risk, browsers previously allowed you to disable this feature. Now they are going in the opposite direction. Hyperlink auditing is an HTML standard that allows the creation of special links that ping back to a specified URL when they are clicked on. These pings are done in the form of a POST request to the specified web page that can then examine the request headers to see what page the link was clicked on. The article concludes that "Firefox and Brave win the award" for people who want this click-tracking capability disabled -- since "only Brave and Firefox currently disable it by default, and do not appear to have any plans on enabling it in the future."' -- source: https://news.slashdot.org/story/19/04/07/2338244 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 Aren't People Abandoning Windows For Linux?
by Peter Reutemann 08 Apr '19

08 Apr '19

'This weekend SlashGear published "Reasons to Abandon Windows For Linux," making their case to "Windows users who are curious about the state of Linux for mainstream computing." It tries to enumerate specific reasons why Linux might be the better choice, arguing among other things that: * Updates on Linux are fast and "rarely call for a restart" -- and are also more complete. "Updates are typically downloaded through a 'Software Updater' application that not only checks for operating system patches, but also includes updates for the programs that you've installed from the repository." * Windows "tries to serve a variety of markets...cramming in a scattered array of features" -- and along those lines, that Microsoft "has gradually implemented monetization schemes and methods for extracting user data." And yet you're still paying for that operating system, while Linux is less bloated and "free forever." * "Because less people use Linux, the platform is less targeted by malware and tends to be more secure than Windows" The article also touches on a few other points (including battery life), and predicts that problems with Windows are "bound to get worse over time and will only present more of a case for making the switch to Linux." Long-time Slashdot reader shanen shared the article, along with some new thoughts on why people really stay with Windows: I think the main "excuse" is the perception of reliability, which is really laughable if you've actually read the EULA. Microsoft certainly doesn't have to help anyone at all. I would argue that Windows support is neither a bug nor a feature, but just a marketing ploy. Their original submission suggests that maybe Linux needs to buttress the perception of its reliability with a better financial model -- possibly through a new kind of crowd funding which could also be extended to all open source software, or even to journalism).' -- source: https://linux.slashdot.org/story/19/04/07/2111218 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/

Ongoing DNS hijackings target unpatched consumer routers
by Peter Reutemann 05 Apr '19

05 Apr '19

'A wave of DNS hijacking attacks that abuse Google's cloud computing service is causing consumer routers to connect to fraudulent and potentially malicious websites and addresses, a security researcher has warned. By now, most people know that Domain Name System servers translate human-friendly domain names into the numeric IP addresses that computers need to find other computers on the Internet. Over the past four months, a blog post published Thursday said, attackers have been using Google cloud service to scan the Internet for routers that are vulnerable to remote exploits. When they find susceptible routers, the attackers then use the Google platform to send malicious code that configures the routers to use malicious DNS servers.' -- source: https://arstechnica.com/information-technology/2019/04/ongoing-dns-hijackin… 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 End of the Desktop?
by Peter Reutemann 04 Apr '19

04 Apr '19

'Steven J. Vaughan-Nichols, writing for ComputerWorld : Of course, at one time, to get any work done with a computer, you first had to learn a lot, about computers, operating systems, commands and more. Eventually, "friendly" became the most important adverb in computing circles, and we've reached the point in user-friendliness that people don't even talk about it anymore. Today, Google has shown with its Chrome OS that most of us can pretty much do anything we need to do on a computer with just a web browser. But Google's path is not Microsoft's path. Instead, it's moving us first to Windows as desktop as a service (DaaS) via Microsoft Managed Desktop (MMD). This bundles Windows 10 Enterprise, Office 365 and Enterprise Mobility + Security and cloud-based system management into Microsoft 365 Enterprise. The next step, Windows Virtual Desktop, enables companies to virtualize Windows 7 and 10, Office 365 ProPlus apps and other third-party applications on Azure-based virtual machines. If all goes well, you'll be able to subscribe to Windows Virtual Desktop this fall. Of course, Virtual Desktop is a play for business users -- for now. I expect Virtual Desktop to be offered to consumers in 2020. By 2025, Windows as an actual desktop operating system will be a niche product. Sound crazy? Uh, you do know that Microsoft already really, really wants you to "rent" Office 365 rather than buy Office 2019, don't you? But what about games, you say? We'll always have Windows for games! Will we? Google, with its Google Stadia gaming cloud service, is betting we're ready to move our games to the cloud as well. It's no pipe dream. Valve has been doing pretty well for years now with its Steam variation on this theme. So where is all this taking us? I see a world where the PC desktop disappears for all but a few. Most of us will be writing our documents, filling out our spreadsheets and doing whatever else we now do on our PCs via cloud-based applications on smart terminals running Chrome OS or Windows Lite. If you want a "real" PC, your choices are going to be Linux or macOS.' -- source: https://tech.slashdot.org/story/19/04/04/1724248 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/

'SPURV' Project Brings Windowed Android Apps To Desktop Linux
by Peter Reutemann 04 Apr '19

04 Apr '19

'A new "experimental containerized Android environment" from a company called Collabora allows Android apps to run in floating windows alongside native applications on desktop Linux. You can read all the technical details at the source link, but put simply, 'SPURV' creates a virtual Android device on your Linux computer, much like Bluestacks and other similar tools. There are various components of SPURV that allow the Android environment to play audio, connect to networks, and display hardware-accelerated graphics through the underlying Linux system. The most interesting part is 'SPURV HWComposer,' which renders Android applications in windows, alongside the windows from native Linux applications. This is what sets SPURV apart from (most) other methods of running Android on a computer. For this to work, the Linux desktop has to be using the Wayland display server (some Linux-based OSes use X11). Pre-built binaries for SPURV are not currently available -- you have to build it yourself from the source code. Still, it's an interesting proof-of-concept, and hopefully someone turns it into a full-featured product.

Serious Apache server bug gives root to baddies in shared host environments
by Peter Reutemann 04 Apr '19

04 Apr '19

'The Apache HTTP Server, the Internet’s most widely used Web server, just fixed a serious vulnerability that makes it possible for untrusted users or software to gain unfettered control of the machine the software runs on. CVE-2019-0211, as the vulnerability is indexed, is a local privilege escalation, meaning it allows a person or software that already has limited access to the Web server to elevate privileges to root. From there, the attacker could do just about anything. The vulnerability makes it possible for unprivileged scripts to overwrite sensitive parts of a server’s memory, Charles Fol, the independent researcher who discovered the bug, wrote in a blog post. A malicious script could exploit the vulnerability to gain root. The vulnerability poses the most risk inside Web-hosting facilities that offer shared instances, in which a single physical machine serves content for more than one website. Typically, such servers prevent an administrator of one site from accessing other sites or from accessing sensitive settings of the machine itself.' -- source: https://arstechnica.com/information-technology/2019/04/serious-apache-serve… 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/

Millions of Facebook Records Found on Amazon Cloud Servers
by Peter Reutemann 03 Apr '19

03 Apr '19

'Researchers at UpGuard, a cybersecurity firm, found troves of Facebook user information hiding in plain sight, inadvertently posted publicly on Amazon.com's cloud computing servers. From a report: The discovery shows that a year after the Cambridge Analytica scandal exposed how unsecure and widely disseminated Facebook users' information is online, companies that control that information at every step still haven't done enough to seal up private data, Bloomberg News reports. In one instance, Mexico City-based media company Cultura Colectiva openly stored 540 million records on Facebook users, including identification numbers, comments, reactions and account names. That database was closed on Wednesday after Bloomberg alerted Facebook to the problem and Facebook contacted Amazon. Facebook shares pared their gains after the Bloomberg News report. UpGuard adds: The data sets vary in when they were last updated, the data points present, and the number of unique individuals in each. What ties them together is that they both contain data about Facebook users, describing their interests, relationships, and interactions, that were available to third party developers. As Facebook faces scrutiny over its data stewardship practices, they have made efforts to reduce third party access. But as these exposures show, the data genie cannot be put back in the bottle. Data about Facebook users has been spread far beyond the bounds of what Facebook can control today. Combine that plenitude of personal data with storage technologies that are often misconfigured for public access, and the result is a long tail of data about Facebook users that continues to leak' -- source: https://yro.slashdot.org/story/19/04/03/182215 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 on Social Media: 'It's a Disease. It Seems To Encourage Bad Behavior.'
by Peter Reutemann 03 Apr '19

03 Apr '19

'From a wide-ranging interview of Linus Torvalds with Linux Journal on the magazine's 25th anniversary: Linux Journal: If you had to fix one thing about the networked world, what would it be? Linus: Nothing technical. But, I absolutely detest modern "social media" -- Twitter, Facebook, Instagram. It's a disease. It seems to encourage bad behavior. I think part of it is something that email shares too, and that I've said before: "On the internet, nobody can hear you being subtle". When you're not talking to somebody face to face, and you miss all the normal social cues, it's easy to miss humor and sarcasm, but it's also very easy to overlook the reaction of the recipient, so you get things like flame wars, etc., that might not happen as easily with face-to-face interaction. But email still works. You still have to put in the effort to write it, and there's generally some actual content (technical or otherwise). The whole "liking" and "sharing" model is just garbage. There is no effort and no quality control. In fact, it's all geared to the reverse of quality control, with lowest common denominator targets, and click-bait, and things designed to generate an emotional response, often one of moral outrage. Add in anonymity, and it's just disgusting. When you don't even put your real name on your garbage (or the garbage you share or like), it really doesn't help. I'm actually one of those people who thinks that anonymity is overrated. Some people confuse privacy and anonymity and think they go hand in hand, and that protecting privacy means that you need to protect anonymity. I think that's wrong. Anonymity is important if you're a whistle-blower, but if you cannot prove your identity, your crazy rant on some social-media platform shouldn't be visible, and you shouldn't be able to share it or like it. Linux Journal: Is there any advice you'd like to give to young programmers/computer science students? Linus: I'm actually the worst person to ask. I knew I was interested in math and computers since an early age, and I was largely self-taught until university. And everything I did was fairly self-driven. So I don't understand the problems people face when they say "what should I do?" It's not where I came from at all.' -- source: https://tech.slashdot.org/story/19/04/03/1829244 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 (Not) To Damage A Flash Storage Device

Came across this article <http://wiki.laptop.org/go/How_to_Damage_a_FLASH_Storage_Device> on the OLPC wiki about some of the things to beware of when reformatting a flash device (USB stick or SD card -- what about SSDs?). Basically, if there is a mismatch between the blocking of data at the filesystem level and the device page size, then you could be increasing the number of hardware-level writes by a factor of 2 or more. This leads to a corresponding reduction in the life of the device.

Mozilla Will Run Two Experiments This Month With Firefox To Explore Ways To Fight Push Notification Permission Spam
by Peter Reutemann 02 Apr '19

'Mozilla said this week that it intends to run two experiments over the course of this month to determine the most adequate way of dealing with push notification spam, a growing problem that is slowly deteriorating the web experience for everyone. From a report: The experiments will run in Firefox Nightly (v68) and Firefox Beta (v67). The Firefox Nightly experiment will run from April 1 to April 29. During this time, Mozilla said Firefox Nightly would only allow websites to show a push notification permission only after the user has clicked or pressed a key while on a website. All attempts to show a push notification permission request before a click or key press will be blocked by default. [...] In the last two weeks of the experiment, Firefox will show an icon in the URL bar, but with no visible popup on the page. Users can click this icon and accept any push notification permission requests if they wish so.' -- source: https://news.slashdot.org/story/19/04/02/1941232 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Mint 19.2 'Tina' is On the Way, But the Developers Seem Defeated and Depressed

'Brian Fagioli, reporting for BetaNews: Today should be happy times for the Linux Mint community, as we finally learn some new details about the upcoming version 19.2! It will be based on Ubuntu 18.04 and once again feature three desktop environments -- Xfce, Mate, and Cinnamon. We even found out the code name for Linux Mint 19.2 -- "Tina." And yet, it is hard to celebrate. Why? Because the developers seem to be depressed and defeated. They even appear to be a bit disenchanted with Free Software development overall. Clement Lefebvre, leader of the Linux Mint project, shared a very lengthy blog post today, and it really made me sad. He wrote, "For a team to work, developers need to feel like heroes. They want the same things as users, they are users, they were 'only' users to start with. At some stage they decide to get involved and they start investing time, efforts and emotions into improving our project. What they're looking for the most is support and happiness. They need feedback and information to understand bugs or feature requests and when they're done implementing something, they need to feel like heroes, they literally do, that's part of the reason they're here really." Upon publication of the article, Jason Hicks, Muffin maintainer and member of the Linux Mint team, corroborated the claims made by others.' -- source: https://linux.slashdot.org/story/19/04/02/1359246 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/

SUSE Will Soon Be the Largest Independent Linux Company
by Peter Reutemann 02 Apr '19

02 Apr '19

'At SUSECon in Nashville, Tennessee, European Linux power SUSE CEO Nils Brauckmann said his company would soon be the largest independent Linux company. "That's because, of course, IBM is acquiring Red Hat," reports ZDNet. "But, simultaneously, SUSE has continued to grow for seven-straight years." From the report: Brauckmann said, "We believe that makes our status as a truly independent open source company more important than ever. Our genuinely open-source solutions, flexible business practices, lack of enforced vendor lock-in, and exceptional service are more critical to customer and partner organizations, and our independence coincides with our single-minded focus on delivering what is best for them." Practically speaking, SUSE has been growing by focusing on delivering high-quality Linux and open-source programs and services to enterprise customers. Looking ahead Brauckmann said, "SUSE is better positioned to bring more innovation to customers and partners faster through both organic growth and acquisitions, keeping us on track to provide them with the open solutions that keep them ahead with their own customers in their own markets. We continue to adapt so our customers and partners can succeed." Last year SUSE's revenue grew by 15 percent in fiscal year 2018, and the business is about to surpass the $400 million revenue mark for the first time. SUSE, which sees not quite half of its business in Europe, is also seeing revenue growth around the world. North America, for example, now accounts for almost 40 percent of SUSE's revenues. The company is also expanding. SUSE added more than 300 employees in the last 12 months. For the most part this has been in engineering followed by sales and services. SUSE staff is now approaching 1,750 globally and its plans on continuing to hire aggressively.

HOW TO TRANSFER FILES FROM ANDROID-PDA TO LINUX-LAPTOP ====================================================== I'm running Android 7.1 on an OPPO A73 phone/PDA, and sometimes need to transfer photos and other files to a laptop running Linux Mint 19.1. Steps required on the PDA: 1) install termux from Android PlayStore 2) install rsync (in termux, type: pkg install rsync) 3) install perl (in termux, type: pkg install perl) 4) in termux, type: termux-setup-storage (also automatically creates links) 5) in termux, type: cd storage, then type: ls to see the following directories: dcim: photos/videos taken with the PDA downloads: stuff you downloaded movies: music: pictures: shared: everything (includes the above directories) In the following examples we will use /dcim/ and /downloads/: oppopictures.prl ================ In termux, type: perl system "rsync -av /sdcard/DCIM/ username_on_laptop\@1.2.3.4:/oppo_pictures/" This will transfer photos (*.jpg) and videos (*.mp4) to /oppo_pictures/Camera/, and screenshots to /oppo_pictures/Screenshots/. Directory /oppo/pictures/ must exist on the laptop and grant world-access (chmod 777). Ignore rsync error-messages regarding file-attributes. oppodownloads.prl ================= In termux, type: perl system "rsync -av /storage/downloads/ username_on_laptop\@1.2.3.4:/oppo_downloads/" This will transfer files to /oppo_downloads/. Directory /oppo_downloads/ must exist on laptop and grant world-access (chmod 777). Ignore rsync error-messages regarding file-attributes. NOTE: REPLACE the numbers 1.2.3.4 in the above examples with your laptop's IP-address (as provided by your IP-router). Get them using ifconfig. Theoretically you could do the above using the /shared/ directory to get a copy of Android-files.

Researchers Find 36 New Security Flaws In LTE Protocol
by Peter Reutemann 28 Mar '19

28 Mar '19

'A group of academics from South Korea have identified 36 new vulnerabilities in the Long-Term Evolution (LTE) standard used by thousands of mobile networks and hundreds of millions of users across the world. The vulnerabilities allow attackers to disrupt mobile base stations, block incoming calls to a device, disconnect users from a mobile network, send spoofed SMS messages, and eavesdrop and manipulate user data traffic. They were discovered by a four-person research team from the Korea Advanced Institute of Science and Technology Constitution (KAIST), and documented in a research paper they intend to present at the IEEE Symposium on Security and Privacy in late May 2019. The Korean researchers said they found 51 LTE vulnerabilities, of which 36 are new, and 15 have been first identified by other research groups in the past. They discovered this sheer number of flaws by using a technique known as fuzzing --a code testing method that inputs a large quantity of random data into an application and analyzes the output for abnormalities, which, in turn, give developers a hint about the presence of possible bugs. The resulting vulnerabilities, see image below or this Google Docs sheet, were located in both the design and implementation of the LTE standard among the different carriers and device vendors. The KAIST team said it notified both the 3GPP (industry body behind LTE standard) and the GSMA (industry body that represents mobile operators), but also the corresponding baseband chipset vendors and network equipment vendors on whose hardware they performed the LTEFuzz tests.' -- source: https://it.slashdot.org/story/19/03/28/2035257 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/

ASUS Releases Fix For ShadowHammer Malware Attack
by Peter Reutemann 26 Mar '19

'ASUS may have inadvertently pushed malware to some of its computers through its update tool, but it at least it has a fix ready to go. The PC maker has released a new version of its Live Update software for laptops that addresses the ShadowHammer backdoor attack. It also promised "multiple security verification mechanisms" to reduce the chances of further attacks, and started using an "enhanced end-to-end encryption mechanism." There are upgrades to the behind-the-scenes server system to prevent future attacks, ASUS added. The company simultaneously reiterated the narrow scope of ShadowHammer, noting that the malware targeted a "very small and specific user group." It's believed to be an Advanced Persistent Threat -- that is, a state-backed assault against organizations rather than everyday users. Other ASUS devices weren't affected, according to a notice. While the fix is reassuring, it also raises questions as to why the systems weren't locked down earlier. Update tools are prime targets for hackers precisely because they're both trusted and have deep access to the operating system -- tight security is necessary to prevent an intruder from hijacking the process.' -- source: https://hardware.slashdot.org/story/19/03/26/2025229 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/

I have written up some thoughts about those horrible happenings in Christchurch today. You can read them here <https://default-cube.deviantart.com/journal/Refuse-To-Be-Terrorized-Christc…>. I hope we learn the right lessons from others who have been here before us, and not repeat too many of their mistakes.

Firefox Lockbox Comes To Android To Ease Password Pain
by Peter Reutemann 26 Mar '19

26 Mar '19

'If you're a Firefox true believer, or even just a Firefox user, your password struggles just got a little easier with the release of Firefox Lockbox for Android devices. From a report: The password manager, based on login information already in Firefox, makes it easier to sign into apps as well. It integrates with login autocomplete systems in both Apple's iOS and Google's Android software, Mozilla said. It's not as fancy as password managers like LastPass, BitWarden, 1Password and Dashlane, and the only browser it works with is Firefox. On the other hand, if you're already in the Firefox world, it's basically already set up for you. There's no migration process as with dedicated password managers.' -- source: https://news.slashdot.org/story/19/03/26/1559243 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 Makes Emails More Dynamic With AMP For Email
by Peter Reutemann 26 Mar '19

'Google today officially launched AMP for Email, its effort to turn emails from static documents into dynamic, web page-like experiences. >From a report: AMP for Email is coming to Gmail, but other major email providers like Yahoo Mail, Outlook and Mail.ru will also support AMP emails. It's been more than a year since Google first announced this initiative. Even by Google standards, that's a long incubation phase, though there's also plenty of backend work necessary to make this feature work. The promise of AMP for Email is that it'll turn basic messages into a surface for actually getting things done. "Over the past decade, our web experiences have changed enormously -- evolving from static flat content to interactive apps -- yet email has largely stayed the same with static messages that eventually go out of date or are merely a springboard to accomplishing a more complex task," Gmail product manager Aakash Sahney writes. "If you want to take action, you usually have to click on a link, open a new tab, and visit another website." With AMP for Email, those messages become interactive. That means you'll be able to RSVP to an event right from the message, fill out a questionnaire, browse through a store's inventory or respond to a comment -- all without leaving your web-based email client.' -- source: https://tech.slashdot.org/story/19/03/26/1838254 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/
