Microsoft Acquires GitHub For $7.5B
by Peter Reutemann 04 Jun '18

04 Jun '18

'As rumored, Microsoft said Monday that it has acquired code repository website GitHub for a whopping sum of $7.5B in Microsoft stock. Microsoft Corporate Vice President Nat Friedman, founder of Xamarin and an open source veteran, will assume the role of GitHub CEO. GitHub's current CEO, Chris Wanstrath, will become a Microsoft technical fellow, reporting to Executive Vice President Scott Guthrie, to work on strategic software initiatives. From the blog post: "Microsoft is a developer-first company, and by joining forces with GitHub we strengthen our commitment to developer freedom, openness and innovation," said Satya Nadella, CEO, Microsoft. "We recognize the community responsibility we take on with this agreement and will do our best work to empower every developer to build, innovate and solve the world's most pressing challenges." Under the terms of the agreement, Microsoft will acquire GitHub for $7.5 billion in Microsoft stock. Subject to customary closing conditions and completion of regulatory review, the acquisition is expected to close by the end of the calendar year. GitHub will retain its developer-first ethos and will operate independently to provide an open platform for all developers in all industries. Developers will continue to be able to use the programming languages, tools and operating systems of their choice for their projects -- and will still be able to deploy their code to any operating system, any cloud and any device. The two companies, together, will "empower developers to achieve more at every stage of the development lifecycle, accelerate enterprise use of GitHub, and bring Microsoft's developer tools and services to new audiences," Microsoft said. A portion of the developer community has opposed the move, with some already leaving the platform for alternative services. Update: In a conference call with reporters, Mr. Nadella said today the company is "all in with open source," and requested people to judge the company's commitment to the open source community with its actions in the recent past, today, and in the coming future. GitHub will remain open and independent, Mr. Nadella said.' -- source: https://developers.slashdot.org/story/18/06/04/1314247 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 4.17 Released
by Peter Reutemann 04 Jun '18

04 Jun '18

'In his weekly message to the Linux community on Sunday, Linus Torvalds announced the release of Linux 4.17. The release comes a couple of months after the first release candidate, and in his message Torvalds also talks about version 5.0 of the Linux kernel. Having previously said that Linux kernel v5.0 "should be meaningless," he said that this next major numerical milestone will come around "in the not too distance future." For now, though, it's version 4.17 -- or Merciless Moray, if you prefer -- that's of interest. Linux kernel 4.17 is not a major release, and Torvalds announced it without much fanfare. "So this last week was pretty calm, even if the pattern of most of the stuff coming in on a Friday made it feel less so as the weekend approached. And while I would have liked even less changes, I really didn't get the feeling that another week would help the release in any way, so here we are, with 4.17 released."' -- source: https://linux.slashdot.org/story/18/06/04/0913249 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Is Said to Have Agreed to Acquire Coding Site GitHub
by Peter Reutemann 04 Jun '18

04 Jun '18

'Microsoft Corp. has agreed to acquire GitHub Inc., the code repository company popular with many software developers, and could announce the deal as soon as Monday, according to people familiar with the matter. GitHub preferred selling the company to going public and chose Microsoft partially because it was impressed by Chief Executive Officer Satya Nadella, said one of the people, who asked not to be identified discussing private information. Terms of the agreement weren't known on Sunday. GitHub was last valued at $2 billion in 2015. GitHub is an essential tool for coders. Many corporations, including Microsoft and Alphabet Inc.'s Google, use GitHub to store their corporate code and to collaborate. It's also a social network of sorts for developers. While GitHub's losses have been significant -- it lost $66 million over three quarters in 2016 -- it had revenue of $98 million in nine months of that year. On Friday, it was reported that Microsoft was in talks with GitHub about an acquisition. Now it seems like it's actually happening. Update: Our sister site, SourceForge, has weighed in. Here is a tool that will import your GitHub project to SourceForge. Update #2: Already, we are seeing plenty of backlash over this news. One user has started a petition to stop Microsoft from buying GitHub.' -- source: https://developers.slashdot.org/story/18/06/03/2042255 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/

Emacs 26.1 Released With New Features
by Peter Reutemann 03 Jun '18

03 Jun '18

'There's a new version of the 42-year-old libre text editor with over 2,000 built-in commands, reports LWN.net: Highlights include a built-in Lisp threading mechanism that provides some concurrency, double buffering when running under X, a redesigned flymake mode, 24-bit color support in text mode, and a systemd [user] unit file. The Free Software Foundation has released a 10,653-word description of all the new features in Emacs 26.1. Here's a couple more: * The Emacs server now has socket-launching support. This allows socket based activation, where an external process like systemd can invoke the Emacs server process upon a socket connection event and hand the socket over to Emacs... This new functionality can be disabled with the configure option '--disable-libsystemd'. * The new function 'call-shell-region' executes a command in an inferior shell with the buffer region as input. * Intercepting hotkeys on Windows 7 and later now works better. * The new user variable 'electric-quote-chars' provides a list of curved quotes for 'electric-quote-mode', allowing user to choose the types of quotes to be used.' -- source: https://news.slashdot.org/story/18/06/01/202205 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/

Atari Launches Linux Gaming Box Starting at $199
by Peter Reutemann 03 Jun '18

03 Jun '18

'Attempts to establish Linux as a gaming platform have failed time and time again, with Valve's SteamOS being the latest high-profile casualty. Yet, Linux has emerged as a significant platform in the much smaller niche of retro gaming, especially on the Raspberry Pi. Atari has now re-emerged from the fog of gaming history with an Ubuntu-based Atari VCS gaming and media streaming console aimed at retro gamers. In addition to games, the Atari VCS will also offer Internet access and optional voice control. With a Bluetooth keyboard and mouse, the system can be used as a standard Linux computer. The catch is that the already delayed systems won't ship until July 2019... By the launch date, Atari plans to have "new and exclusive" games for download or streaming, including "reimagined classic titles from Atari and other top developers," as well as multi-player games. The Atari VCS Store will also offer video, music and other content... The hardware is not open source, and the games will be protected with HDCP. However, the Ubuntu Linux stack based on Linux kernel 4.10 is open source, and includes a "customizable Linux UX." A Linux "sandbox" will be available for developing or porting games and apps. Developers can build games using any Linux compatible gaming engine, including Unity, Unreal Engine, and Gamemaker. Atari also says that "Linux-based games from Steam and other platforms that meet Atari VCS hardware specifications should work." Atari boasts this will be their first device offering online multi-player experiences, and the device will also come pre-loaded with over 100 classic Atari games. An Indiegogo campaign this week seeking $100,000 in pre-orders has already raised over $2.2 million from 8808 backers.' -- source: https://games.slashdot.org/story/18/06/01/2057206 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/

CSS Is Now So Overpowered It Can Deanonymize Facebook Users
by Peter Reutemann 03 Jun '18

03 Jun '18

'Some of the recent additions to the Cascading Style Sheets (CSS) web standard are so powerful that a security researcher has abused them to deanonymize visitors to a demo site and reveal their Facebook usernames, avatars, and if they liked a particular web page of Facebook. Information leaked via this attack could aid some advertisers linking IP addresses or advertising profiles to real-life persons, posing a serious threat to a user's online privacy. The leak isn't specific to Facebook but affects all sites which allow their content to be embedded on other web pages via iframes. The actual vulnerability resides in the browser implementation of a CSS feature named "mix-blend-mode," added in 2016 in the CSS3 web standard. Security researchers have proven that by overlaying multiple layers of 1x1px-sized DIV layers on top of iframes, each layer with a different blend mode, they could determine what's displayed inside it and recover the data, to which parent websites cannot regularly access. This attack works in Chrome and Firefox, but has been fixed in recent versions.' -- source: https://tech.slashdot.org/story/18/06/02/0531202 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/

SVG 2.0 Chicken-And-Egg Dilemma
by Lawrence D'Oliveiro 01 Jun '18

01 Jun '18

From <http://libregraphicsworld.org/blog/entry/gradient-meshes-and-hatching-to-be…>: Essentially, we have arrived to the point where development of a major vector graphics file format for the Web is shaped by inactivity of Mozilla and Google, while Microsoft and W3C do the real work, a developer of one design tool [Inkscape] contributes a lot, but has no say in what goes into the standard, and a vendor [Adobe] of another design tool is taking a wait-and-see stance. By the way, it appears Alexandre Prokoudine has given up the battle with spammers, and has turned off all posting of new comments on his blog.

Chrome and Firefox leaks let sites steal visitors’ Facebook names, profile pics
by Peter Reutemann 01 Jun '18

01 Jun '18

'For more than a year, Mozilla Firefox and Google Chrome may have leaked users’ Facebook usernames, profile pictures, and likes if the users’ browsers visited malicious websites that employed a cutting-edge hack, researchers said Thursday. The data could be extracted through what’s known as a side-channel vulnerability in the browsers’ implementation of new standards for cascading style sheets introduced in 2016. One of the new features known as the “mix-blend-mode” leaked visual content hosted on Facebook to websites that included an iframe linking to it and some clever code to capture the data. Normally, a security concept known as the same-origin policy forbids content hosted on one domain to be available to a different domain. The vulnerability was significant because it allowed hackers to bypass this bedrock principle for two of the Internet’s most widely used browsers. The leak was independently discovered by two different research teams, and it was fixed late last year in version 63 of Chrome and two weeks ago in Firefox 60. While the updated browsers no longer pose a threat to user privacy, one of the researchers who discovered the vulnerability said the increasingly powerful graphics capabilities being added in the HTML5 and CSS standards are likely to make similar hacks possible in the future.' -- source: https://arstechnica.com/information-technology/2018/05/chrome-and-firefox-l… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Chrome 67 Released for Windows, Mac, and Linux
by Peter Reutemann 31 May '18

31 May '18

'Google released earlier today Chrome 67, the latest stable release of its web browser. According to changelogs released with Chrome 67, this version adds support for a Generic Sensors API, improves AR and VR experiences, and deprecates the HTTP-Based Public Key Pinning (HPKP) security feature. Probably the biggest change in Chrome 67 is the addition of the Generic Sensors API. As the name implies, this is an API that exposes data from device sensors to public websites. The new API is based on the Generic Sensor W3C standard. This API is meant primarily for mobile use, and in its current version, websites can use Chrome's Generic Sensors API to access data from a device's accelerometer, gyroscope, orientation and motion sensors. Another API that shipped with Chrome is the WebXR Device API. Developers can use this API to build virtual and augmented reality experiences on Chrome for mobile-based VR headsets like Google Daydream View and Samsung Gear VR, as well as desktop-hosted headsets like Oculus Rift, HTC Vive, and Windows Mixed Reality Headsets.' -- source: https://tech.slashdot.org/story/18/05/30/1440256 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/

Sonic and Ultrasonic Attacks Damage Hard Drives and Crash OSes
by Peter Reutemann 30 May '18

30 May '18

'Attackers can cause potentially harmful hard drive and operating system crashes by playing sounds over low-cost speakers embedded in computers or sold in stores, a team of researchers demonstrated last week. The attacks use sonic and ultrasonic sounds to disrupt magnetic HDDs as they read or write data. The researchers showed how the technique could stop some video-surveillance systems from recording live streams. Just 12 seconds of specially designed acoustic interference was all it took to cause video loss in a 720p system made by Ezviz. Sounds that lasted for 105 seconds or more caused the stock Western Digital 3.5 HDD in the device to stop recording altogether until it was rebooted. The device uses flash storage to house its firmware, but by default it uses a magnetic HDD to store the large quantities of video it records. The attack used a speaker hanging from a ceiling that rested about four inches above the surveillance system's HDD. The researchers didn't remove the casing or otherwise tamper with the surveillance system. The technique was also able to disrupt HDDs in desktop and laptop computers running both Windows and Linux. In some cases, it even required a reboot before the PCs worked properly.

Windows 10 Spring Update Improves Linux On WSL With Unix Sockets and More
by Peter Reutemann 29 May '18

'Windows 10 build 1803 has come out this month, but with some problems. AnandTech has a deep-dive with the review examing many new features including the much better support for Linux. WSL (Windows Subsystem for Linux) now has native Curt and Tar from the command prompt as well as a utility to convert Unix to Windows pathnames called WSLpath.exe which is documented here. In addition it was mentioned on Slashdot in the past about OpenSSH being ported natively to Win32 in certain early builds. It now seems the reason was for Linux interoperability with this Spring Update 2. Unix sockets mean you can run Kali Linux on Windows 10 for penetration testing or run an Apache server in the background with full Linux networking support.

Satya Nadella: “I Believe Right Now Microsoft Is Probably On The Right Side Of History”
by Lawrence D'Oliveiro 27 May '18

27 May '18

Interview of the Microsoft boss by the Daily Telegraph <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=120597…>: ... Nadella's four years in charge cannot be described as anything but a success. Under his watch, its share price has increased by 170 per cent, finally overtaking the levels from the peak of the dotcom boom. Except that share price seems a somewhat short-sighted way of measuring a company’s success. Look at HP. "I always make this case, which is if it was not for Microsoft's openness, the web wouldn't have happened. I was talking to [web creator Sir] Tim Berners-Lee yesterday and I sort of said: 'Think about the current ecosystems and how closed and how walled gardened and riddled with all kinds of ways they've rigged it, [compared] to where we were.' Talk about rewriting history. The Web was growing by leaps and bounds long before Microsoft even noticed it (remember how the first edition of Bill Gates’ book “The Road Ahead” didn’t even mention it?). Netscape was the leader and de-facto setter of standards, until Microsoft belatedly entered the race, and took over by giving away their product for free. Then we had the long period of stagnation under Internet Explorer 6, until Firefox came in to jolt them out of their complacency, followed by Apple’s Safari and Google’s Chrome. So to say that “Microsoft’s openness” had anything to do with it is just shamelessly false.

There Are Real Reasons For Linux To Replace ifconfig, netstat and Other Classic Tools
by Peter Reutemann 27 May '18

27 May '18

'One of the ongoing system administration controversies in Linux is that there is an ongoing effort to obsolete the old, cross-Unix standard network administration and diagnosis commands of ifconfig, netstat and the like and replace them with fresh new Linux specific things like ss and the ip suite. Old sysadmins are generally grumpy about this; they consider it yet another sign of Linux's 'not invented here' attitude that sees Linux breaking from well-established Unix norms to go its own way. Although I'm an old sysadmin myself, I don't have this reaction. Instead, I think that it might be both sensible and honest for Linux to go off in this direction. There are two reasons for this, one ostensible and one subtle. The ostensible surface issue is that the current code for netstat, ifconfig, and so on operates in an inefficient way. Per various people, netstat et al operate by reading various files in /proc, and doing this is not the most efficient thing in the world (either on the kernel side or on netstat's side). You won't notice this on a small system, but apparently there are real impacts on large ones. Modern commands like ss and ip use Linux's netlink sockets, which are much more efficient. In theory netstat, ifconfig, and company could be rewritten to use netlink too; in practice this doesn't seem to have happened and there may be political issues involving different groups of developers with different opinions on which way to go. (Netstat and ifconfig are part of net-tools, while ss and ip are part of iproute2.) However, the deeper issue is the interface that netstat, ifconfig, and company present to users. In practice, these commands are caught between two masters. On the one hand, the information the tools present and the questions they let us ask are deeply intertwined with how the kernel itself does networking, and in general the tools are very much supposed to report the kernel's reality. On the other hand, the users expect netstat, ifconfig and so on to have their traditional interface (in terms of output, command line arguments, and so on); any number of scripts and tools fish things out of ifconfig output, for example. As the Linux kernel has changed how it does networking, this has presented things like ifconfig with a deep conflict; their traditional output is no longer necessarily an accurate representation of reality.' -- source: https://linux.slashdot.org/story/18/05/27/1448211 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 GNOME Foundation is grateful for this donation and plans on using these funds to increase staff to streamline operations and to grow its support of the GNOME Project and the surrounding ecosystem.

Ubuntu - Upgrading to 18.04
by Ian Stewart 17 May '18

17 May '18

Hi, Ubuntu users are probably aware that about three weeks ago version 18.04.0 was released. This is a Long Term Support (LTS) release. If you are running version 17.10, and your "Software & Updates" --> "Updates" --> "Notify me of a new Ubuntu version:" is set to either "For any new version" or "For long-term support versions", then you will probably have received a GUI pop-up screen asking you if you wanted to do an on-line upgrade to 18.04. I had no problems when performing the on-line upgrade with Ubuntu/Mate 17.10 to 18.04. (Which is better that when I did the 17.04 to 17.10, where I struck an application dependency problem.) I also have a 16.04 LTS Ubuntu/Mate laptop, and I was expecting a pop-up and to get prompted to do the software upgrade to 18.04 LTS, but all I could get was a message to say my 16.04 version was up-to-date. In reading this askubuntu posting: https://askubuntu.com/questions/1028624/not-able-to-upgrade-from-16-04-lts-… ...I found someone has posted the following comment: Upgrades from LTS releases are scheduled after the first patch - 18.04.1 which is usually a month after the first release. They need to make sure everything goes smoothly and then the software manager will allow it. If you're anxious, which based on my experience you shouldn't be cause there are probably tons of bugs, you can still force that upgrade, but that's not recommended. sudo do-release-upgrade -d ...despite it not being recommended I did the "sudo do-release-upgrade -d" and it upgraded my laptop from 16.04 to 18.04, and it seems to be booting and working fine. However, if you read the posting, then be aware that not everyone has had the same level of success: "I did a sudo do-release-upgrade -d on an ASUS SonicMaster with Ubuntu 16.04 LTS on it. After the upgrade, I restarted the machine, and the computer couldn't boot due to some infinite loops while showing messages regarding PCI bus." cheers, Ian.

'Korora, a Fedora-based Linux distro, halted its development this month, BetaNews' Brian Fagioli spotted Wednesday. The announcement would irk many, as Korora consistently received positive feedback from critics and users alike. News outlet ZDNet once described Korora as "Fedora++", while Slashdot readers, too, spoke highly of the distro. At the same time, the announcement should come as little surprise to anyone who has been tracking Korora's work. In a blog post, Korora team wrote: Korora for the forseeable future is not going to be able to march in cadence with the Fedora releases. In addition to that, for the immediate future there will be no updates to the Korora distribution. Our team is infinitesimal (currently 1 developer and 2 community managers) compared to many other distributions, we don't have the luxury of being able to dedicate the amount of time we would like to spend on the project and still satisfy our real life obligations. So we are taking a little sabbatical to avoid complete burn out and rejuvenate ourselves and our passion for Korora/Fedora and wider open source efforts. The team had expressed similar concerns earlier this year: For the past few years Korora has released a new version in line with each Fedora version. That means that approximately twice a year we prepare, test and create 5 different ISO versions. This is as well as, among other things, developing new projects, supporting existing releases and planning the future versions. As each team member has different skills some tasks, such as development, can only be done by one person. All this is done in our spare time along side our job, family and personal responsibilities. For a very small team, currently 3 people plus the occasional input from others, this is a lot of work. It means that often Korora has to take a back seat when real life intrudes. This isn't the first time Korora had to abruptly pause its development. In 2007, Christopher Smart, who kickstarted Korora (at the time based on Gentoo Linux), had discontinued the project -- only to revive it three years later.' -- source: https://linux.slashdot.org/story/18/05/16/1352245 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/

Attention PGP Users: New Vulnerabilities Require You To Take Action Now
by Peter Reutemann 14 May '18

14 May '18

'A group of European security researchers have released a warning about a set of vulnerabilities affecting users of PGP and S/MIME. From a report: EFF has been in communication with the research team, and can confirm that these vulnerabilities pose an immediate risk to those using these tools for email communication, including the potential exposure of the contents of past messages. The full details will be published in a paper on Tuesday at 07:00 AM UTC (3:00 AM Eastern, midnight Pacific). In order to reduce the short-term risk, we and the researchers have agreed to warn the wider PGP user community in advance of its full publication. Our advice, which mirrors that of the researchers, is to immediately disable and/or uninstall tools that automatically decrypt PGP-encrypted email. Until the flaws described in the paper are more widely understood and fixed, users should arrange for the use of alternative end-to-end secure channels, such as Signal, and temporarily stop sending and especially reading PGP-encrypted email.' -- source: https://it.slashdot.org/story/18/05/14/149222 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/

Malware Found In the Ubuntu Snap Store
by Peter Reutemann 14 May '18

14 May '18

'Oh, snap! Just because some packages are available to install directly from the Ubuntu Software Center doesn't make them safe. This is proved by a recent discovery of malware in some snap packages from the Ubuntu Snaps Store. At least two of the snap packages, 2048buntu and hextris, uploaded to the Ubuntu Snaps Store by user Nicolas Tomb, contained malware. All packages by Nicolas have since been removed from the Ubuntu Snaps Store, "pending further investigations." The report comes from a bug which mentions that the 2048buntu snap package (and other packages by Nicolas Tomb) contains a hidden cryptocurrency miner inside.

Same IP Address For Wired And Wireless Connections
by Lawrence D'Oliveiro 10 May '18

10 May '18

I did something I thought was a little dodgy in my DHCP server config, namely I assigned the same IP address to both the Ethernet and Wi-Fi MAC addresses for my laptop. I figured this was OK so long as I turned one off before turning on the other. Today, I tried breaking that rule. I started a large rsync transfer over wi-fi, decided it was too slow, and plugged in an Ethernet cable. And it worked! After a few seconds, I was able to turn off the wi-fi, and the transfer continued without a hiccup. Has anyone else tried this?

Multiple OS Vendors Release Security Patches After Misinterpreting Intel Docs
by Peter Reutemann 09 May '18

09 May '18

'Almost all major OS vendors released security patches yesterday after a researcher discovered that some OS makers have misinterpreted an Intel CPU debug feature and left their systems open to attacks. From a report: The vulnerability is in how the OS vendors implemented a hardware debug mechanism for Intel x86-64 architectures -- and more specifically the MOV SS and POP SS instructions. "In certain circumstances after the use of certain Intel x86-64 architecture instructions, a debug exception pointing to data in a lower ring (for most operating systems, the kernel Ring 0 level) is made available to operating system components running in Ring 3," the CERT/CC team explained in an advisory published yesterday. Explained in layman's terms, "this may allow an attacker to utilize operating system APIs to gain access to sensitive memory information or control low-level operating system functions." Operating systems that mishandle this debug exception and had their systems open to attacks include Apple, Microsoft, FreeBSD, Red Hat, Ubuntu, SUSE Linux, and other Linux distros based on the Linux Kernel -- which is also affected.' -- source: https://it.slashdot.org/story/18/05/09/1724220 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox Moves Browsers Into Post-Password Future With WebAuthn Tech
by Peter Reutemann 09 May '18

09 May '18

'Today, Mozilla released Firefox 60 for Windows, Mac, Linux and Android, and with it arrives Web Authentication API for desktop browsers. From a report: Firefox 60 supports technology called Web Authentication, or WebAuthn for short, that can be used to grant you access to websites with a physical authentication device like a YubiKey dongle, biometric identity proof using an Android phone's fingerprint reader or the iPhone's Face ID, and some other alternatives to passwords. Passwords are a particular problem on the web. Fake websites can coax you to type in credentials that then can be used to steal money from your bank account or snoop your email -- a problem called phishing. Even if you pick hard-to-guess passwords, never reuse them on multiple sites and always remember them, passwords still aren't that strong a foundation for security these days. We're still a long way away from a post-password future, but WebAuthn is an important step, if nothing else, in making sites more secure.' -- source: https://news.slashdot.org/story/18/05/09/1932232 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/

Cloudflare Embraces ARM As Qualcomm Might Leave

Chrome 66 Arrives With Autoplaying Content Blocked By Default
by Peter Reutemann 09 May '18

'Google today launched Chrome 66 for Windows, Mac, Linux, and Android. The desktop release includes autoplaying content muted by default, security improvements, and new developer features. You can update to the latest version now using the browser's built-in silent updater or download it directly from google.com/chrome. In our tests, autoplaying content that is muted still plays automatically. Autoplaying content with sound, whether it has visible controls or not, and whether it is set to play on loop or not, simply does not start playing. Note that this is all encompassing -- even autoplaying content you are expecting or is the main focus of the page does not play. YouTube videos, for example, no longer start playing automatically. And in case that's not enough, or if a page somehow circumvents the autoplaying block, you can still mute whole websites.' -- source: https://tech.slashdot.org/story/18/04/18/0410202 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/

Drupal Sites Fall Victims To Cryptojacking Campaigns
by Peter Reutemann 08 May '18

08 May '18

'After the publication of two severe security flaws in the Drupal CMS, cybercrime groups have turned their sights on this web technology in the hopes of finding new ground to plant malware on servers and make money through illegal cryptocurrency mining. [...] Now, as time passes by, more malware campaigns targeting Drupal sites are getting off the ground -- and two of them have been spotted the past week. The most recent of these campaigns has been discovered by US security researcher Troy Mursch. The researcher discovered a group that gained access to Drupal sites and hid a version of the Coinhive in-browser cryptocurrency miner inside a file named "jquery [dot] once [dot] js?v=1.2," loaded on each of the compromised sites. Mursch initially tracked down the infected files to over 100,000 domains, then narrowed down the results to 80,000 domains, and finally confirmed the infection on at least 348 sites where the in-browsing mining operation was actually taking place.' -- source: https://it.slashdot.org/story/18/05/07/1636258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Ubuntu Considering an HTML5-Based OS Installer

You Can Now Run Linux Apps On Chrome OS
by Peter Reutemann 08 May '18

'Google today announced Chrome OS is getting Linux support. "As a result, Chromebooks will soon be able to run Linux apps and execute Linux commands," reports VentureBeat.

From the report: "Just go to wherever you normally get those apps, whether it's on the websites or through apt-get in the Linux terminal, and seamless get those apps like any other Linux distribution," Chrome OS director of product management Kan Liu told VentureBeat. Support for Linux apps means developers will finally be able to use a Google device to develop for Google's platforms, rather than having to depend on Windows, Mac, or Linux machines. And because Chrome OS doesn't just run Chrome OS-specific apps anymore, developers will be able to create, test, and run any Android or web app for phones, tablets, and laptops all on their Chromebooks. Without having to switch devices, you can run your favorite IDE -- as long as there is a Debian Linux version (for the curious, Google is specifically using Debian Stretch here -- code in your favorite language and launch projects to Google Cloud with the command line.

Eight New Meltdown-Like Flaws Found
by Peter Reutemann 06 May '18

06 May '18

'Researchers have found eight new flaws in computer central processing units that resemble the Meltdown and Spectre bugs revealed in January, a German computing magazine reported on Thursday. The magazine, called c't, said it was aware of Intel Corp's plans to patch the flaws, adding that some chips designed by ARM Holdings, a unit of Japan's Softbank, might be affected, while work was continuing to establish whether Advanced Micro Devices chips were vulnerable... The magazine said Google Project Zero, one of the original collective that exposed Meltdown and Spectre in January, had found one of the flaws and that a 90-day embargo on going public with its findings would end on May 7... "Considering what we have seen with Meltdown and Spectre, we should expect a long and painful cycle of updates, possibly even performance or stability issues," said Yuriy Bulygin, chief executive officer of hardware security firm Eclypsium and a former Intel security researcher. "Hopefully, Meltdown and Spectre led to improvements to the complicated process of patching hardware." Neowin now reports that Intel "is expected to release microcode updates in two waves; one in May, and the other in August."' -- source: https://it.slashdot.org/story/18/05/05/1730203 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 At The Leading Edge Of Enterprise-Level Storage
by Lawrence D'Oliveiro 26 Apr '18

26 Apr '18

First of all, some background (as I understand it): * “NVMe” is a standard for accessing storage (normally flash rather than hard drives) via a PCI-E bus <https://en.wikipedia.org/wiki/NVM_Express>. * “NVME-oF” (“NVMe over Fabrics”) (mentioned in the above article) is a further spec that allows one node to access storage attached to another node. Sounds like NBD, really <https://en.wikipedia.org/wiki/Network_block_device>, though the term “RDMA” (“Remote Direct Memory Access”) gets tossed around. So, this article <http://www.theregister.co.uk/2018/04/26/nvme_fabric_over_fibre_channel/> says things like NVME-oF “has to be implemented across network or fabric and, so far, Ethernet, with ROCE (RDMA over Converged Ethernet), is the favoured one”, though other lower-layer protocols also work. In particular, the writer is interviewing an industry guru about the prospects for FC-NVMe, which uses Fibre Channel as the transport. A couple of quotes caught my eye: Since the low-level driver isn't a part of the OS, like NVMe-oF, but rather supplied by the HBA vendor (Emulex or QLogic), the deployment for OSes outside the Linux model should be more agile... You must run a recent version of Linux; no other OSes have NVMe-oF drivers available (yet). In other words, NVME-oF is pretty much Linux-only at the moment. But it would be hardware-independent, which should mean you can mix and match storage from different vendors. Unlike FC-NVMe, where the “HBA vendor” needs to supply hardware-specific drivers. In other, other words, NVME-oF works only on Linux, but makes you “hardware-agile”, while FC-NVMe is hardware-specific but should (hopefully) be “OS-agile”. Which kind of “agility” will turn out to be more important, I wonder?

Was Our Census Data Secure?
by Lawrence D'Oliveiro 25 Apr '18

25 Apr '18

According to this article <http://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=12038826>, when we were filling out our census data online last month, it was actually going through the servers of a company called Incapsula, which was scanning the unencrypted data for malware. Since the company is based in the US, this naturally raises concerns about US Government access to the data of NZ residents and citizens. On the one hand, the article says “this is not a data breach”, but on the other hand Adding to the researchers' concerns, Stats NZ's digital key that is required to decrypt the data sent over TLS secured connections is now distributed across Incapsula's global network, Teague and Culnane said. "Our non-exhaustive search found that servers in Australia, the US, as well as New Zealand, all had the Stats NZ key," they added. Digital TLS keys are supposed to be protected and should only be kept on the servers that they relate to, the researchers said. If keys are leaked, attackers could use them to impersonate Stats NZ servers. and further down they use the phrase “clear security flaw”. Stats NZ insists the company is trusted and “Goverment-approved”. Given it’s also protecting the GCSB, I guess that is already very literally true.

We can't, so we need to accept that our voting systems are insecure. We need an election system that is resilient to the threats. And for many parts of the system, that means paper.

What Private Browsing Mode Really Means
by Lawrence D'Oliveiro 25 Apr '18

25 Apr '18

Seems like a lot of people <http://www.theregister.co.uk/2018/04/24/private_web_browsing_study/> have the wrong idea about what is really “private” in private browsing mode. Many of them believe that * Activity while logged into an account (e.g. Google) will not be saved in that account’s history * Bookmarks made in private mode are not visible in standard mode * It prevents websites from tracking their location * It affords better protection against malware * It obscures their IP address. None of which is true. To its credit, when you open a private window in Firefox, it clearly states the things that are hidden and the things that are not.

Google Accused of Showing 'Total Contempt' for Android Users' Privacy
by Peter Reutemann 23 Apr '18

23 Apr '18

'On the heels of a terse privacy debate, Google may have found another thing to worry about: its attempt to rethink the traditional texting system. From a report: Joe Westby is Amnesty International's Technology and Human Rights researcher. Recently, in response to Google's launch of a new messaging service called "Chat", Westby argued that Google, "shows total contempt for Android users' privacy." "With its baffling decision to launch a messaging service without end-to-end encryption, Google has shown utter contempt for the privacy of Android users and handed a precious gift to cybercriminals and government spies alike, allowing them easy access to the content of Android users' communications. Following the revelations by CIA whistleblower Edward Snowden, end-to-end encryption has become recognized as an essential safeguard for protecting people's privacy when using messaging apps. With this new Chat service, Google shows a staggering failure to respect the human rights of its customers," Westby contended. Westby continued, saying: "In the wake of the recent Facebook data scandal, Google's decision is not only dangerous but also out of step with current attitudes to data privacy."' -- source: https://tech.slashdot.org/story/18/04/23/1946251 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/

“Drupalgeddon2” touches off arms race to mass-exploit powerful Web servers
by Peter Reutemann 22 Apr '18

22 Apr '18

'Attackers are mass-exploiting a recently fixed vulnerability in the Drupal content management system that allows them to take complete control of powerful website servers, researchers from multiple security companies are warning. At least three different attack groups are exploiting "Drupalgeddon2," the name given to an extremely critical vulnerability Drupal maintainers patched in late March, researchers with Netlab 360 said Friday. Formally indexed as CVE- 2018-7600, Drupalgeddon2 makes it easy for anyone on the Internet to take complete control of vulnerable servers simply by accessing a URL and injecting publicly available exploit code. Exploits allow attackers to run code of their choice without having to have an account of any type on a vulnerable website. The remote-code vulnerability harkens back to a 2014 Drupal vulnerability that also made it easy to commandeer vulnerable servers. Drupalgeddon2 "is under active attack, and every Drupal site behind our network is being probed constantly from multiple IP addresses," Daniel Cid, CTO and founder of security firm Sucuri, told Ars. "Anyone that has not patched is hacked already at this point. Since the first public exploit was released, we are seeing this arms race between the criminals as they all try to hack as many sites as they can." China-based Netlab 360, meanwhile, said at least three competing attack groups are exploiting the vulnerability. The most active group, Netlab 360 researchers said in a blog post published Friday, is using it to install multiple malicious payloads, including cryptocurrency miners and software for performing distributed denial-of-service attacks on other domains. The group, dubbed Muhstik after a keyword that pops up in its code, relies on 11 separate command-and-control domains and IP addresses, presumably for redundancy in the event one gets taken down.' -- source: https://arstechnica.com/information-technology/2018/04/drupalgeddon2-touche… 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 Chrome Users Have Installed Malware Posing as Ad Blockers
by Peter Reutemann 19 Apr '18

19 Apr '18

'Andrey Meshkov, the cofounder of ad-blocker AdGuard, recently got curious about the number of knock-off ad blocking extensions available for Google's popular browser Chrome. These extensions were deliberately styled to look like legitimate, well-known ad blockers, but Meshkov wondered why they existed at all, so he downloaded one and took a look at the code. "Basically I downloaded it and checked what requests the extension was making," Meshkov told me over the phone. "Some strange requests caught my attention." Meshkov discovered that the AdRemover extension for Chrome -- which had over 10 million users -- had code hidden inside an image that was loaded from the remote command server, giving the extension creator the ability to change its functions without updating. This alone is against Google's policy, and after Meshkov wrote about a few examples on AdGuard's blog, many of which had millions of downloads, Chrome removed the extensions from the store. I reached out to Google, and a spokesperson confirmed that these extensions had been removed.' -- source: https://yro.slashdot.org/story/18/04/19/1946250 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/

Ask Slashdot: Is There a Good Alternative to Facebook?
by Peter Reutemann 18 Apr '18

18 Apr '18

'Long-time Slashdot reader Lauren Weinstein argues that fixing Facebook may be impossible because "Facebook's entire ecosystem is predicated on encouraging the manipulation of its users by third parties who posses the skills and financial resources to leverage Facebook's model. These are not aberrations at Facebook -- they are exactly how Facebook was designed to operate." Meanwhile one fund manager is already predicting that sooner or later every social media platform "is going to become MySpace," adding that "Nobody young uses Facebook," and that the backlash over Cambridge Analytica "quickens the demise." But Slashdot reader silvergeek asks, "is there a safe, secure, and ethical alternative?" to which tepples suggests "the so-called IndieWeb stack using the h-entry microformat." He also suggests Diaspora, with an anonymous Diaspora user adding that "My family uses a server I put up to trade photos and posts... Ultimately more people need to start hosting family servers to help us get off the cloud craze... NethServer is a pretty decent CentOS based option." Meanwhile Slashdot user Locke2005 shared a Washington Post profile of Mastodon, "a Twitter-like social network that has had a massive spike in sign-ups this week." Mastodon's code is open-source, meaning anybody can inspect its design. It's distributed, meaning that it doesn't run in some data center controlled by corporate executives but instead is run by its own users who set up independent servers. And its development costs are paid for by online donations, rather than through the marketing of users' personal information... Rooted in the idea that it doesn't benefit consumers to depend on centralized commercial platforms sucking up users' personal information, these entrepreneurs believe they can restore a bit of the magic from the Internet's earlier days -- back when everything was open and interoperable, not siloed and commercialized. The article also interviews the founders of Blockstack, a blockchain-based marketplace for apps where all user data remains local and encrypted. "There's no company in the middle that's hosting all the data," they tell the Post. "We're going back to the world where it's like the old-school Microsoft Word -- where your interactions are yours, they're local and nobody's tracking them." On Medium, Mastodon founder Eugene Rochko also acknowledges Scuttlebutt and Hubzilla, ending his post with a message to all social media users: "To make an impact, we must act." Lauren Weinstein believes Google has already created an alternative to Facebook's "sick ecosystem": Google Plus. "There are no ads on Google+. Nobody can buy their way into your feed or pay Google for priority. Google doesn't micromanage what you see. Google doesn't sell your personal information to any third parties..." And most importantly, "There's much less of an emphasis on hanging around with those high school nitwits whom you despised anyway, and much more a focus on meeting new persons from around the world for intelligent discussions... G+ posts more typically are about 'us' -- and tend to be far more interesting as a result." (Even Linus Torvalds is already reviewing gadgets there.) Wired has also compiled their own list of alternatives to every Facebook service. But what are Slashdot's readers doing for their social media fix? Leave your own thoughts and suggestions in the comments. Is there a good alternative to Facebook?' -- source: https://tech.slashdot.org/story/18/03/25/0039218 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/

Cyber-Espionage Groups Are Increasingly Leveraging Routers in Their Attacks
by Peter Reutemann 12 Apr '18

12 Apr '18

'Catalin Cimpanu, reporting for BleepingComputer: Cyber-espionage groups -- also referred to as advanced persistent threats (APTs) -- are using hacked routers more and more during their attacks, according to researchers at Kaspersky Lab. "It's not necessarily something new. Not something that just exploded," said Costin Raiu, director of Global Research and Analysis Team (GReAT) at Kaspersky Lab, in a webinar today. "We've seen a bunch of router attack throughout the years. A very good example is SYNful Knock, a malicious implant for Cisco [routers] that was discovered by FireEye but also threat actors such as Regin and CloudAtlas. Both APTs have been known to have and own proprietary router implants." But the number of APTs leveraging routers for attacks has gone steadily up in the past year, and the tactic has become quite widespread in 2018. For example, the Slingshot APT (believed to be a US Army JSOC operation targeting ISIS militants) has used hacked MikroTik routers to infect victims with malware.' -- source: https://tech.slashdot.org/story/18/04/12/1932248 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/

Biometric and App Logins Will Soon Be Pushed Across the Web
by Peter Reutemann 10 Apr '18

10 Apr '18

'Soon, it will be much easier to log into more websites using a hardware key plugged into your laptop, a dedicated app, or even the fingerprint scanner on your phone. Motherboard: On Tuesday, a spread of organizations and businesses, including top browser vendors such as Microsoft and Google, announced a new standards milestone that will streamline the process for web developers to add extra login methods to their sites, potentially keeping consumers' accounts and data more secure. "For users, this will be a natural transition. People everywhere are already using their fingers and faces to 'unlock' their mobile phones and PCs, so this will be natural to them -- and more convenient," Brett McDowell, executive director at the FIDO Alliance, one of the organizations involved in setting up the standard, told Motherboard in an email. "What they use today to 'unlock' will soon allow them to 'login' to all their favorite websites and a growing number of native apps that already includes Bank of America, PayPal, eBay and Aetna," he added. Passwords continue to be one of the weaker points in online security. A hacker may phish a target's password and log into their account, or take passwords from one data breach and use them to break into accounts on another site. The login standard, called Web Authentication (WebAuthn), will let potentially any website or online service use apps, security keys, or biometrics as a login method instead of a password, or use those alternative approaches as a second method of verification. The key here is making it easy and open for developers to use, and for it to work across all different brands of browsers. The functionality is already available in Mozilla's Firefox, and will be rolled out to Microsoft's Edge and Google Chrome in the new few months. Opera has committed to supporting WebAuthn as well.' -- source: https://yro.slashdot.org/story/18/04/10/1357241 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox Follows Chrome and Blocks the Loading of Most FTP Resources
by Peter Reutemann 10 Apr '18

10 Apr '18

'Mozilla says it will follow in the steps of Google Chrome and start blocking the loading of FTP subresources inside HTTP and HTTPS pages. >From a report: By FTP subresources, we refer to files loaded via the FTP protocol inside img, script, or iframe tags that have a src="ftp://". FTP links placed inside normal angle bracket links or typed directly in the browser's address bar will continue to work. The reasoning is that FTP is an insecure protocol that doesn't support modern encryption techniques and will inherently break many other built-in browser security and privacy features, such as HSTS, CSP, XSA, or others. Furthermore, many malware distribution campaigns often rely on compromising FTP servers and redirecting or downloading malware on users' computers via FTP subresources. Mozilla engineers say FTP subresource blocking will ship with Firefox 61, currently scheduled for release on June 26.' -- source: https://tech.slashdot.org/story/18/04/10/188244 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/

Torvalds Opposes Tying UEFI Secure Boot to Kernel Lockdown Mode
by Peter Reutemann 08 Apr '18

08 Apr '18

'The kernel lockdown feature further restricts access to the kernel by user-space with what can be accessed or modified... Pairing that with UEFI SecureBoot unconditionally is meeting some resistance by Linus Torvalds. The goal of kernel lockdown, which Linus Torvalds doesn't have a problem with at all, comes down to "prevent both direct and indirect access to a running kernel image, attempting to protect against unauthorised modification of the kernel image and to prevent access to security and cryptographic data located in kernel memory, whilst still permitting driver modules to be loaded." But what has the Linux kernel creator upset with are developers trying to pair this unconditionally with UEFI SecureBoot. Linus describes Secure Boot as being "pushed in your face by people with an agenda." But his real problem is that Secure Boot would then imply Kernel Lockdown mode... "Tying these things magically together IS A BAD IDEA."' -- source: https://linux.slashdot.org/story/18/04/07/2159245 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 Kernel To Lose A Few Architectures
by Lawrence D'Oliveiro 03 Apr '18

03 Apr '18

Looking at the source code <https://elixir.bootlin.com/linux/latest/source/> for the latest (4.16) Linux kernel, I see support for 31 different major processor architectures currently <https://elixir.bootlin.com/linux/latest/source/arch>. However, the next, 4.17 kernel is due to drop the ability to run on 8 of them <http://www.theregister.co.uk/2018/04/03/linux_kernel_4_16_released/>, due to the fact that nobody is using them any more--or at least, nobody with an interest in implementing new kernels <http://lkml.iu.edu/hypermail/linux/kernel/1804.0/00306.html>. Interesting to read Arnd Bergmann’s observations on what these dead-end architectures have in common: In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. In contrast, CPU instruction sets that remain popular and have actively maintained kernel ports tend to all be used across multiple licensees.

Adobe Is Helping Some 60 Companies Track People Across Devices
by Peter Reutemann 31 Mar '18

31 Mar '18

'Neowin reports of Adobe's recent announcement of its new Marketing Cloud Device Co-op initiative: The announcement of the new solution for tracking customers across devices was made at the Adobe Summit this week in Las Vegas to a digital marketing conference. According to an Adobe blog post released earlier this month citing Forrester, consumers are increasingly accessing multiple devices before making a purchase decision -- an average of 5.5 connected devices per person. This behavior creates a challenge for retailers, who cannot easily target people in their marketing campaigns, ultimately depending on Facebook or Google to track people instead of devices. Both Facebook and Google are able to do this job because of the massive amount of users logged into their ecosystems regularly, so most retailers have been opting to use those platforms as a way to reach potential customers. But Adobe's approach is to provide a platform agnostic solution acting as a glue between the world's biggest brands' own data management platforms. In order for Device Co-op to work, each company that has joined the initiative will provide Adobe with "cryptographically hashed login IDs" and HTTP header data, which Adobe claims will completely hide the customer's identity. This data will be used to create groups of devices used by the same person or household, which will then be made available to all the members of the initiative so they can target people on different devices, instead of creating one customer profile per device, as can be seen from the example given in the image above. Until now, some 60 companies have joined the Adobe initiative, including brands such as Subway, Sprint, NFL, Lenovo, Intel, Barnes & Noble, and Subaru. Also, preliminary measurements made by Adobe indicate that Device Co-op could link up to 1.2 billion devices worldwide, based on the amount of accesses seen by current members. But it is important to note that the initiative is currently collecting data of U.S. and Canada users only. Adobe is claiming the initiative will not disclose a user's identity to its members, including any personal data, but, given the recent Facebook and Cambridge Analytica scandal, many will be skeptical of those claims. Thankfully, Adobe is allowing users to completely opt out all of their devices from the services via this website.' -- source: https://yro.slashdot.org/story/18/03/31/0059259 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 Prestigious Free Software Award Goes to Karen Sandler
by Peter Reutemann 31 Mar '18

31 Mar '18

'Each year the Free Software award goes to someone making "a great contribution to the progress and development of free software, through activities that accord with the spirit of free software." This year's winner is a former executive of the GNOME Foundation, Karen Sandler. Jeremy Allison - Sam, Slashdot reader #8,157, brought this announcement. Richard Stallman, President of the FSF, presented Sandler with the award during a ceremony. Stallman highlighted Sandler's dedication to software freedom. Stallman told the crowd that Sandler's "vivid warning about backdoored nonfree software in implanted medical devices has brought the issue home to people who never wrote a line of code. Her efforts, usually not in the public eye, to provide pro bono legal advice to free software organizations and [with Software Freedom Conservancy] to organize infrastructure for free software projects and copyleft defense, have been equally helpful." In her acceptance speech, Sandler spoke about her dedication to free software as a patient, advocate and professional.

Security Experts See Chromebooks as a Closed Ecosystem That Improves Security
by Peter Reutemann 31 Mar '18

31 Mar '18

'The founder of Rendition Security believes his daughter "is more safe on a Chromebook than a Windows laptop," and he's not the only one. CNET's staff reporter argues that Google's push for simplicity, speed, and security "ended up playing off each other." mspohr shared this article: Heading to my first security conference last year, I expected to see a tricked-out laptop running on a virtual machine with a private network and security USB keys sticking out -- perhaps something out of a scene from "Mr. Robot." That's not what I got. Everywhere I went I'd see small groups of people carrying Chromebooks, and they'd tell me that when heading into unknown territory it was their travel device... "If you want prehardened security, then Chromebooks are it," said Kenneth White, director of the Open Crypto Audit Project. "Not because they're Google, but because Chrome OS was developed for years and it explicitly had web security as a core design principle...." Drewry and Liu focused on four key features for the Chromebook that have been available ever since the first iteration in 2010: sandboxing, verified boots, power washing and quick updates. These provided security features that made it much harder for malware to pass through, while providing a quick fix-it button if it ever did. That's not to say Chrome OS is impervious to malware. Cybercriminals have figured out loopholes through Chrome's extensions, like when 37,000 devices were hit by the fake version of AdBlock Plus. Malicious Android apps have also been able to sneak through the Play Store. But Chrome OS users mostly avoided massive cyberattack campaigns like getting locked up with ransomware or hijacked to become part of a botnet. Major security flaws for Chrome OS, like ones that would give an attacker complete control, are so rare that Google offers rewards up to $200,000 to anyone who can hack the system. The article argues that "Fewer software choices mean limited options for hackers. Those are some of the benefits that have led security researchers to warm up to the laptops... "Chrome OS takes an approach to security that's similar to the one Apple takes with iOS and its closed ecosystem."' -- source: https://tech.slashdot.org/story/18/03/31/0443257 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 RISC V Processor Gets Support From Google, Samsung, Qualcomm, and Tesla
by Peter Reutemann 31 Mar '18

31 Mar '18

'Google, Qualcomm, and Samsung "are among 80 tech companies joining forces to develop a new open-source chip design for new technologies like self-driving vehicles," writes Seeking Alpha, citing a (pay-walled) report on The Information. "Western Digital and Nvidia also plan to use the new chip design for some of their products," while Tesla "has joined the RISC-V Foundation and is considering using the tech in its new chip efforts." MIT Technology Review adds that while Arm had hoped to bring their low-power/high performance processors to AI and self-driving cars, "The company that masterminded the processor inside your smartphone may find that a set of free-to-use alternative designs erode some of its future success."' -- source: https://news.slashdot.org/story/18/03/31/0622248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft's Windows 7 Meltdown Fixes From January and February Made PCs More Insecure
by Peter Reutemann 30 Mar '18

30 Mar '18

'Microsoft's January and February security fixes for Intel's Meltdown processor vulnerability opened up an even worse security hole on Windows 7 PCs and Server 2008 R2 boxes. From a report: This is according to researcher Ulf Frisk, who previously found glaring shortcomings in Apple's FileVault disk encryption system. We're told Redmond's early Meltdown fixes for 64-bit Windows 7 and Server 2008 R2 left a crucial kernel memory table readable and writable for normal user processes. This, in turn, means any malware on those vulnerable machines, or any logged-in user, can manipulate the operating system's memory map, gain administrator-level privileges, and extract and modify any information in RAM. The Meltdown chip-level bug allows malicious software, or unscrupulous logged-in users, on a modern Intel-powered machine to read passwords, personal information, and other secrets from protected kernel memory. But the security fixes from Microsoft for the bug, on Windows 7 and Server 2008 R2, issued in January and February, ended up granting normal programs read and write access to all of physical memory' -- source: https://tech.slashdot.org/story/18/03/28/2010240 Time to move to another operating system...

Yet Another Microsoft Windows Reorg
by Lawrence D'Oliveiro 30 Mar '18

30 Mar '18

From <https://arstechnica.com/gadgets/2018/03/windows-leader-terry-myerson-out-as…>: The Windows platform has many masters. It is important for both Microsoft's client and server businesses, of course, but it's also fundamental to the Azure platform. While it has become increasingly unified, responsibility for its development (and financial reporting) has often been split between divisions. Conway’s Law says that any piece of software reflects the organizational structure that produced it. The fact that there is no single mind in charge of the overall product will inevitably manifest itself in discontinuities in the characteristics of that product. Yes, I know: scratch that future tense. It already has.

Many VPN Providers Leak Customer's IP Address via WebRTC Bug
by Peter Reutemann 28 Mar '18

28 Mar '18

'Around 20% of today's top VPN solutions are leaking the customer's IP address via a WebRTC bug known since January 2015, and which apparently some VPN providers have never heard of. The discovery belongs to Paolo Stagno, a security researcher who goes by the pseudonym of VoidSec, and who recently audited 83 VPN apps on this old WebRTC IP leak. Stagno says he found that 17 VPN clients were leaking the user's IP address while surfing the web via a browser. The researcher published his results in a Google Docs spreadsheet. The audit list is incomplete because Stagno didn't have the financial resources to test all commercial VPN clients.' -- source: https://yro.slashdot.org/story/18/03/28/1813213 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/

Chromebooks In Schools?
by Lawrence D'Oliveiro 28 Mar '18

28 Mar '18

In among this article about Apple’s new push to get IPads used in schools <https://arstechnica.com/gadgets/2018/03/analysis-new-ipads-will-help-apple-…> is the interesting information that Google Chromebooks are heavily used throughout the US school system: Google offers G Suite for Education for free, sans some features. Adding the full suite of enterprise features costs only $4 per user per month, compared to $25 per user per month for other kinds of organizations. Papers are typed in Google Docs. Presentations are done using Google Presentations. Each student has a Google email account assigned through the district. Homework is handed out and done entirely on Chromebooks in many classes. In so many words, Google has spread its tentacles throughout the entire school district at every level ... Are Chromebooks used in schools here? I noticed a couple of units on sale in OfficeMax when I dropped in there a few weeks ago. I don’t recall seeing them anywhere else in town.

Bring your own Linux to Windows with new open source tool
by Peter Reutemann 27 Mar '18

27 Mar '18

'After starting with Ubuntu, Microsoft has added a number of Linux distributions to its Windows Subsystem for Linux (WSL) Linux runtime environment. A Windows machine can simultaneously offer an Ubuntu, SUSE, Debian, and Kali "personality," providing users with a choice of the different distributions' preferences and package management. But if your distribution isn't yet available or if you want a Linux installation that's customized just the way you like it, there's now an answer: Microsoft has an open source tool for building your own Linux package. The tool is aimed at two groups: distribution owners (so they can produce a bundle to ship through the Microsoft Store) and developers (so they can create custom distributions and sideload them onto their development systems). Microsoft's tool provides the basic glue between Windows and the Linux distribution. It handles telling the system about the distribution and performing initial setup such as user creation, and it can be customized to—for example—print a message of the day when the distribution is started.' -- source: https://arstechnica.com/gadgets/2018/03/microsofts-new-open-source-tool-let… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

As predicted, more speculative execution processor attacks are discovered
by Peter Reutemann 26 Mar '18

26 Mar '18

'Researchers from the College of William and Mary, Carnegie Mellon, the University of California Riverside, and Binghamton University have described a security attack that uses the speculative execution features of modern processors to leak sensitive information and undermine the security boundaries that operating systems and software erect to protect important data. That probably sounds familiar. The Spectre attacks, published earlier this year, take advantage of the speculative execution features of modern processors to leak sensitive information. The new attack, named BranchScope by the researchers, shares some similarity with variant 2 of the Spectre attack, as both BranchScope and Spectre 2 take advantage of the behavior of the processor's branch predictor.' -- source: https://arstechnica.com/gadgets/2018/03/its-not-just-spectre-researchers-re… 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/

Shodan Search Exposes Thousands of Servers Hosting Passwords and Keys
by Peter Reutemann 25 Mar '18

25 Mar '18

'Thousands of etcd servers "are spitting sensitive passwords and encrypted keys," reports Fossbytes: Security researcher Giovanni Collazo was able to harvest 8781 passwords, 650 AWS access keys, 23 secret keys, and 8 private keys. First, he ran a query on the hacker search engine Shodan that returned around 2300 servers running etcd database. Then, he ran a simple script that gave him the login credentials stored on these servers which can be used to gain access to CMSs, MySQL, and PostgreSQL databases, etc. etcd is a database used by computing clusters to store and exchange passwords and configuration settings between servers and applications over the network. With the default settings, its programming interface can return administrative login credentials without any authentication upfront... All of the data he harvested from around 1500 servers is around 750MB in size... Collazo advises that anyone maintaining etcd servers should enable authentication, set up a firewall, and take other security measures. Another security research independently verified the results, and reported that one MySQL database had the root password "1234".' -- source: https://developers.slashdot.org/story/18/03/24/1943239 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Facebook Scraped Call, Text Message Data For Years From Android Phones
by Peter Reutemann 25 Mar '18

25 Mar '18

'This past week, a New Zealand man was looking through the data Facebook had collected from him in an archive he had pulled down from the social networking site. While scanning the information Facebook had stored about his contacts, Dylan McKay discovered something distressing: Facebook also had about two years worth of phone call metadata from his Android phone, including names, phone numbers, and the length of each call made or received. This experience has been shared by a number of other Facebook users who spoke with Ars, as well as independently by us -- my own Facebook data archive, I found, contained call-log data for a certain Android device I used in 2015 and 2016, along with SMS and MMS message metadata. In response to an email inquiry about this data gathering by Ars, a Facebook spokesperson replied, "The most important part of apps and services that help you make connections is to make it easy to find the people you want to connect with. So, the first time you sign in on your phone to a messaging or social app, it's a widely used practice to begin by uploading your phone contacts." The spokesperson pointed out that contact uploading is optional and installation of the application explicitly requests permission to access contacts. And users can delete contact data from their profiles using a tool accessible via Web browser. If you granted permission to read contacts during Facebook's installation on Android a few versions ago -- specifically before Android 4.1 (Jelly Bean) -- that permission also granted Facebook access to call and message logs by default. The permission structure was changed in the Android API in version 16. But Android applications could bypass this change if they were written to earlier versions of the API, so Facebook API could continue to gain access to call and SMS data by specifying an earlier Android SDK version. Google deprecated version 4.0 of the Android API in October 2017 -- the point at which the latest call metadata in Facebook user's data was found. Apple iOS has never allowed silent access to call data. You are able to have Facebook delete the data it collects from you, "but it's not clear if this deletes just contacts or if it also purges call and SMS metadata," reports Ars. Generally speaking, if you're concerned about privacy, you shouldn't share your contacts and call-log data with any mobile application.' -- source: https://yro.slashdot.org/story/18/03/25/056246 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/

Raspberry Pi 3 Model B+ Benchmarks Show Significantly Improved Performance

Hate-Speech Laws In Europe
by Lawrence D'Oliveiro 24 Mar '18

24 Mar '18

<https://www.techdirt.com/articles/20180321/17581339475/spanish-hate-anti-te…>: People are being arrested and charged with speech having nothing to with promoting hate or terrorism. ... It's gotten so bad Amnesty International -- an entity that usually spends its time decrying the acts of dictators and brutal authoritarians -- has felt compelled to speak up about Spain's terrible speech laws. ... The report also notes several other European countries are also beginning to curtail the rights of their citizens in their quest to target hate speech and international terrorism. Germany's hate speech law roll out has been an unmitigated disaster and other countries like France and Italy seem all too willing to join Spain and Germany in killing satire, parody, and content they just don't agree with. All of this is being done under the heading of "public safety," but in reality, the public is no safer and will develop an unhealthy fear of their own governments.

TLS 1.3 Has Been Approved
by Lawrence D'Oliveiro 24 Mar '18

24 Mar '18

The latest version of TLS (the official name for what used to be called “SSL”, i.e. the protocol that your browser uses for URLs beginning “https://”) is now an official IETF standard <http://www.theregister.co.uk/2018/03/23/tls_1_3_approved_ietf/>. This should not only make the setup of secure connections quicker, but also harder to crack. ... banks and businesses complained that, thanks to the way the new protocol does security, they will be cut off from being able to inspect and analyze TLS 1.3 encrypted traffic flowing through their networks, and so potentially be at greater risk from attack. Unfortunately, that self-same ability to decrypt secure traffic on your own network can also be potentially used by third parties to grab and decrypt communications. An effort to effectively insert a backdoor into the protocol was met with disdain and some anger by internet engineers, many of whom pointed out that it will still be possible to introduce middleware to monitor and analyze internal network traffic. Note the key phrase “forward secrecy”. This means that, even if your private key should become compromised down the track, this will still not help attackers decrypt any records they may have kept of your secure communications prior to that. And yes, you can expect the usual suspects to be unhappy about the introduction of such a feature.

Firefox In 2018: We'll Tackle Bad Ads, Breach Alerts, Autoplay Video, Says Mozilla
by Peter Reutemann 24 Mar '18

24 Mar '18

'Firefox maker Mozilla has outlined its 2018 roadmap to make the web less intrusive and safer for users. First up, Mozilla says it will proceed and implement last year's experiment with a breach alerts service, which will warn users when their credentials have been leaked or stolen in a data breach. Mozilla aims to roll out the service around October. Breach Alerts is based on security consultant Troy Hunt's data breach site Have I Been Pwned. Firefox will also implement a similar block on autoplay video to the one Chrome 66 will introduce next month, and that Safari already has. However, Dotzler says Firefox's implementation will "provide users with a way to block video auto-play that doesn't break websites". This feature is set to arrive in Firefox 62, which is scheduled for release in May. After Firefox 62 the browser will gain an optional Chrome-like ad filter and several privacy-enhancing features similar to those that Apple's WebKit developers have been working on for Safari's Intelligent Tracking Prevention. By the third quarter of 2018, Firefox should also be blocking ad-retargeting through cross-domain tracking. It's also going to move all key privacy controls into a single location in the browser, and offer more "fine-grained" tracking protection. Dotzler says Mozilla is in the "early stages" of determining what types of ads Firefox should block by default. Also on the roadmap is a feature that arrived in Firefox 59, released earlier this month. A new Global Permissions feature will help users avoid having to deny every site that requests permission for location, camera, microphone and notifications. Beyond security and privacy, Mozilla plans to build on speed-focused Quantum improvements that came in Firefox 57 with smoother page rendering.' -- source: https://news.slashdot.org/story/18/03/23/2110244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Microsoft announced this week that it will launch the next major release of Windows Server later this year with better support for hybrid workloads, Linux workloads, and hyper-converged infrastructure. >From a report: This release will succeed Windows Server 2016, which was made generally available in October 2016. While Microsoft moved to twice-yearly updates for Windows Server starting last year, the company bundles those changes into a long-term servicing channel once every two or three years for administrators who prefer less frequent releases. Those companies that haven't moved over to the semi-annual channel will get their first taste of Windows Server's Linux and Kubernetes support, which are currently in beta.' -- source: https://tech.slashdot.org/story/18/03/22/1647243 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/

Artificial Intelligence And The Future of Online Content Moderation

Report on a workshop on the use of artificial intelligence in governing communication online <https://freedom-to-tinker.com/2018/03/21/artificial-intelligence-and-the-fu…>: Over the course of the day, [the writer] learned many things about automated filtering that [he] hadn’t previously thought about. • Regulators and platforms are under tremendous pressure to act, based on the assumption that the technical problems are easy. • Takedown requests are a frequent instrument for censorship. • The larger platforms share content hashes of unwanted content, but the database and process are opaque. • Different countries have very different definitions of unlawful content. • Norms and speech evolve over time, often rapidly. In other words, it seems to me that, whether they are doing it deliberately or not, the regulators are pushing more and more power into the hands of the social-media platforms.

Mozilla Launches a Petition Asking Facebook To Do More For User Privacy
by Peter Reutemann 21 Mar '18

21 Mar '18

'After it was revealed that the personal data of 50 million Facebook users was shared without consent, Mozilla is calling on the social network to ensure that user privacy is protected by default, particularly when it comes to apps. Ashley Boyd, Mozilla's vice president of advocacy, says that billions of Facebook users are unknowingly at risk of having their data passed on to third parties. He says: "If you play games, read news or take quizzes on Facebook, chances are you are doing those activities through third-party apps and not through Facebook itself. The default permissions that Facebook gives to those third parties currently include data from your education and work, current city and posts on your timeline."' -- source: https://tech.slashdot.org/story/18/03/21/182253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

IBM Unveils the 'World's Smallest Computer'
by Peter Reutemann 19 Mar '18

19 Mar '18

'On the first day of IBM Think 2018, the company's flagship conference, IBM has unveiled what it claims is the world's smallest computer. It's smaller than a grain of salt and features the computer power of the x86 chip from 1990. Mashable first spotted this gem: The computer will cost less than ten cents to manufacture, and will also pack "several hundred thousand transistors," according to the company. These will allow it to "monitor, analyze, communicate, and even act on data." It works with blockchain. Specifically, this computer will be a data source for blockchain applications. It's intended to help track the shipment of goods and detect theft, fraud, and non-compliance. It can also do basic AI tasks, such as sorting the data it's given. According to IBM, this is only the beginning. "Within the next five years, cryptographic anchors -- such as ink dots or tiny computers smaller than a grain of salt -- will be embedded in everyday objects and devices," says IBM head of research Arvind Krishna. If he's correct, we'll see way more of these tiny systems in objects and devices in the years to come. It's not clear yet when this thing will be released -- IBM researchers are currently testing its first prototype.

Linux Mint 19 'Tara' Cinnamon Will Be Faster
by Peter Reutemann 19 Mar '18

19 Mar '18

'Mint developers say they feel the app-launching time on the Linux distro seemed slow when using the Cinnamon desktop environment. So, they are working on fixing it. BetaNews reports: Windows build time was four times slower with Cinnamon compared to Metacity, while recovery time was nearly four times slower too. So yes, app-launching on Cinnamon -- as of today -- is slow comparatively. The big benefit to pinpointing a problem, however, is that it is the first step in solving it. And so, Linux Mint 19 Cinnamon will be faster as a result. "We developed a little script and a method to measure how long it took to flood the desktop environment with the creation of 200 windows. We could then measure the time reported by the script to build these 200 windows, and the time it actually took the desktop environment to recover from it and have these windows placed/mapped correctly and ready to be interacted with. Both measures were significantly higher in Cinnamon than in other desktops," says The Linux Mint Team.' -- source: https://linux.slashdot.org/story/18/03/19/1648259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Joins Group Working To 'Cure' Open-Source Licensing Issues
by Peter Reutemann 19 Mar '18

19 Mar '18

'Microsoft is joining Red Hat, Facebook, Google and IBM in committing to extending right to "cure" open source licensing noncompliance before taking legal measures. From a report: On March 19, officials from Microsoft -- along with CA Technologies, Cisco, HPE, SAP and SUSE -- said they'd work with open together with the already-committed vendors to provide more "predictability" for users of open source software. "The large ecosystems of projects using the GPLv2 and LGPLv2.x licenses will benefit from adoption of this more balanced approach to termination derived from GPLv3," explained Red Hat in a press release announcing the new license-compliance partners. The companies which have agreed to adopt the "Common Cure Rights Commitment" said before they file or continue to prosecute those accused of violating covered licenses, they will allow for users to cure and reinstate their licenses.' -- source: https://news.slashdot.org/story/18/03/19/1720228 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/
