WAV Audio Files Are Now Being Used To Hide Malicious Code
by Peter Reutemann 21 Oct '19

21 Oct '19

'Two reports published in the last few months show that malware operators are experimenting with using WAV audio files to hide malicious code. The first of these new malware campaigns abusing WAV files was reported back in June by Symantec security researchers who said they spotted a Russian cyber-espionage group known as Waterbug (or Turla) using WAV files to hide and transfer malicious code from their server to already-infected victims. The second malware campaign was spotted this month by BlackBerry Cylance. In a report published today and shared with ZDNet last week, Cylance said it saw something similar to what Symantec saw a few months before. But while the Symantec report described a nation-state cyber-espionage operation, Cylance said they saw the WAV steganography technique being abused in a run-of-the-mill crypto-mining malware operation.' -- source: https://it.slashdot.org/story/19/10/20/200249 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

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

21 Oct '19

'A publicly-funded group of designers, artists and privacy experts from Amsterdam have designed a smart home system prototype to "prove it's technically possible to build a privacy respecting smart home while maintaining convenience." Its controller uses an Arduino Nano to disconnect the system from the internet during times when it's not in use. They're building everything on Mozilla's open smart home gateway software. The system's microphone is a separate USB device that can be easily unplugged. For extra security, the devices don't even use wifi to communicate. "The Candle devices offer the advantages of a smart home system -- such as voice control, handy automations and useful insights -- without the downsides of sending your data to the cloud and feeling watched in your own home," explains their blurb for Dutch Design Week, where they're launching their prototypes of trust-worthy smart locks, thermostats, and other Internet of Things devices: Most smart devices promises us an easier life, but they increasingly disappoint; they eavesdrop, share our data with countless third parties, and offer attractive targets to hackers. Candle is different. Your data never leaves your home, all devices work fine without an internet connection, and everything is open source and transparent. One of the group's members is long-time Slashdot reader mrwireless, who shares an interesting observation: Smart homes track everything that happens inside them. For developing teenagers, this makes it more difficult to sneak in a date or break the rules in other subtle ways, which is a normal, healthy part of growing up. Candle is a prototype smart home that tries to mitigate these issue. It has given its sensors the ability to generate fake data for a while. In the future, children could get a monthly fake data allowance. Some of the devices have "skirts", simple fabric covers that can be draped over the devices to hide their screen. If you own a dust sensor, this can be useful if your mother in law comes over and you haven't vacuumed in a while.' -- source: https://yro.slashdot.org/story/19/10/20/216238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

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

18 Oct '19

'A potentially serious vulnerability in Linux may make it possible for nearby devices to use Wi-Fi signals to crash or fully compromise vulnerable machines, a security researcher said. The flaw is located in the RTLWIFI driver, which is used to support Realtek Wi-Fi chips in Linux devices. The vulnerability triggers a buffer overflow in the Linux kernel when a machine with a Realtek Wi-Fi chip is within radio range of a malicious device. At a minimum, exploits would cause an operating-system crash and could possibly allow a hacker to gain complete control of the computer. The flaw dates back to version 3.10.1 of the Linux kernel released in 2013. "The bug is serious," Nico Waisman, who is a principal security engineer at Github, told Ars. "It's a vulnerability that triggers an overflow remotely through Wi-Fi on the Linux kernel, as long as you're using the Realtek (RTLWIFI) driver." The vulnerability is tracked as CVE-2019-17666. Linux developers proposed a fix on Wednesday that will likely be incorporated into the OS kernel in the coming days or weeks. Only after that will the fix make its way into various Linux distributions.' -- source: https://arstechnica.com/information-technology/2019/10/unpatched-linux-flaw… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

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

18 Oct '19

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

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

18 Oct '19

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

Germany's Cybersecurity Agency Recommends Firefox As Most Secure Browser
by Peter Reutemann 18 Oct '19

18 Oct '19

'Firefox is the only browser that received top marks in a recent audit carried out by Germany's cyber-security agency -- the German Federal Office for Information Security (or the Bundesamt fur Sicherheit in der Informationstechnik -- BSI). The BSI tested Mozilla Firefox 68 (ESR), Google Chrome 76, Microsoft Internet Explorer 11, and Microsoft Edge 44. The tests did not include other browsers like Safari, Brave, Opera, or Vivaldi. The audit was carried out using rules detailed in a guideline for "modern secure browsers" that the BSI published last month, in September 2019. The BSI normally uses this guide to advise government agencies and companies from the private sector on what browsers are safe to use. The article includes a list of all the minimum requirements required for the BSI to consider a browser "secure." It also lists the areas where the other browsers failed, such as: Lack of support for a master password mechanism (Chrome, IE, Edge); No built-in update mechanism (IE), and No option to block telemetry collection (Chrome, IE, Edge)' -- source: https://news.slashdot.org/story/19/10/17/2136219 Cheers, Pete -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hard drives not mounting
by Ian Young 17 Oct '19

17 Oct '19

Hi John (et al) I am going to assume these are drives formatted NTFS. Of late I have encountered drives from Windows machines which Linux won't mount, I think ntfs-3g is a bit finicky about this in recent versions. Get in touch with me directly if you wish, I have a gadget which will connect drives via USB to avoid having to put them into a machine. Some distributions may be able to see the drives even if Mint doesn't wish to, we could try various versions.

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

17 Oct '19

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

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

17 Oct '19

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

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

17 Oct '19

'Free and open source software enables the world as we know it in 2019. From Web servers to kiosks to the big data algorithms mining your Facebook feed, nearly every computer system you interact with runs, at least in part, on free software. And in the larger tech industry, free software has given rise to a galaxy of startups and enabled the largest software acquisition in the history of the world. Free software is a gift, a gift that made the world as we know it possible. And from the start, it seemed like an astounding gift to give. So astounding in fact that it initially made businesses unaccustomed to this kind of generosity uncomfortable. These companies weren't unwilling to use free software, it was simply too radical and by extension too political. It had to be renamed: "open source." Once that happened, open source software took over the world. Recently, though, there's been a disturbance in the open source force. Within the last year, companies like Redis Labs, MongoDB, and Confluent all changed their software licenses, moving away from open source licenses to more restrictive terms that limit what can be done with the software, making it no longer open source software. The problem, argue Redis Labs, MongoDB and others, is a more modern tech trend: hosted software services. Also known as, "the cloud." Also known as Amazon AWS. Amazon, for its part, came out swinging, releasing its own version of the code behind Elastic Search this spring in response to licensing changes at Elastic (the company behind Elastic Search). And besides a new trademark dispute over Amazon's naming convention, Elastic has a very different response from that of MongoDB and Redis—it hasn't said a word in protest.' -- source: https://arstechnica.com/information-technology/2019/10/is-the-software-worl… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hard drives
by john 17 Oct '19

17 Oct '19

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

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

17 Oct '19

'Fedora -- as a Linux distribution -- will celebrate the 15th anniversary of its first release in November, though its technical lineage is much older, as Fedora Core 1 was created following the discontinuation of Red Hat Linux 9 in favor of Red Hat Enterprise Linux (RHEL). Five years after the start of Fedora.next, the distribution is on the right track -- stability has improved, and work on minimizing hard dependencies in packages and containers, including more audio/video codecs by default, flicker-free boot, and lowering power consumption for notebooks, among other changes, have greatly improved the Fedora experience, while improvements in upstream projects such as GNOME and KDE have likewise improved the desktop experience. In a wide-ranging interview with TechRepublic, Fedora project leader Matthew Miller discussed lessons learned from the past, popular adoption and competing standards for software containers, potential changes coming to Fedora, as well as hot-button topics, including systemd.' -- source: https://linux.slashdot.org/story/19/10/16/1712207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google's Auto-Delete Tools Are Practically Worthless For Privacy
by Peter Reutemann 15 Oct '19

15 Oct '19

'By default, Google collects a vast amount of data on users' behavior, including a lifelong record of web searches, locations, and YouTube views. But amid a privacy backlash and ongoing regulatory threats, the company has started to hype its recently released privacy tools, like the ability to automatically delete some of the data it collects about you -- data that helps power its $116 billion ad business. [...] In reality, these auto-delete tools accomplish little for users, even as they generate positive PR for Google. Experts say that by the time three months rolls around, Google has already extracted nearly all the potential value from users' data, and from an advertising standpoint, data becomes practically worthless when it's more than a few months old. "Anything up to one month is extremely valuable," says David Dweck, the head of paid search at digital ad firm WPromote. "Anything beyond one month, we probably weren't going to target you anyway." Dweck says that in the digital ad industry, recent activity is essential. If you start searching on Google for real estate or looking up housing values, for instance, Google might lump you into a "prospective home buyers" category for advertisers. That information becomes instantly valuable to realtors, appraisers, and lenders for ad targeting, and it could remain valuable for a while as other companies, such as painters or appliance brands, try to follow up on your home buying. Still, it's unusual for advertisers to target users based on their activity from months earlier, Dweck says.' -- source: https://yro.slashdot.org/story/19/10/15/1933230 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

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

15 Oct '19

'A vulnerability has been discovered in Sudo -- one of the most important, powerful, and commonly used utilities that comes as a core command installed on almost every UNIX and Linux-based operating system. The vulnerability in question is a sudo security policy bypass issue that could allow a malicious user or a program to execute arbitrary commands as root on a targeted Linux system even when the "sudoers configuration" explicitly disallows the root access. Sudo, stands for "superuser do," is a system command that allows a user to run applications or commands with the privileges of a different user without switching environments -- most often, for running commands as the root user. The vulnerability, tracked as CVE-2019-14287 and discovered by Joe Vennix of Apple Information Security, is more concerning because the sudo utility has been designed to let users use their own login password to execute commands as a different user without requiring their password. What's more interesting is that this flaw can be exploited by an attacker to run commands as root just by specifying the user ID "-1" or "4294967295." That's because the function which converts user id into its username incorrectly treats -1, or its unsigned equivalent 4294967295, as 0, which is always the user ID of root user. The vulnerability affects all Sudo versions prior to the latest released version 1.8.28, which has been released today.' -- source: https://linux.slashdot.org/story/19/10/14/2231235 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

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

14 Oct '19

'"Apple, which often positions itself as a champion of privacy and human rights, is sending some IP addresses from users of its Safari browser on iOS to Chinese conglomerate Tencent -- a company with close ties to the Chinese Communist Party," reports the Reclaim the Net blog: Apple admits that it sends some user IP addresses to Tencent in the "About Safari & Privacy" section of its Safari settings.... The "Fraudulent Website Warning" setting is toggled on by default which means that unless iPhone or iPad users dive two levels deep into their settings and toggle it off, their IP addresses may be logged by Tencent or Google when they use the Safari browser. However, doing this makes browsing sessions less secure and leaves users vulnerable to accessing fraudulent websites... Even if people install a third-party browser on their iOS device, viewing web pages inside apps still opens them in an integrated form of Safari called Safari View Controller instead of the third-party browser. Tapping links inside apps also opens them in Safari rather than a third-party browser. These behaviors that force people back into Safari make it difficult for people to avoid the Safari browser completely when using an iPhone or iPad. Engadget adds that it's "not clear" whether or not Tencent is actually collecting IP addresses from users outside of China. ("You'll see mention of the collection in the U.S. disclaimer, but that doesn't mean it's scooping up info from American web surfers.") But Reclaim the Net points out that the possibility is troubling, in part because Safari is the #1 most popular mobile internet browser in America, with a market share of over 50%.' -- source: https://apple.slashdot.org/story/19/10/14/033225 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

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

14 Oct '19

'Photographer Peter Adams launched a "Faces of Open Source" portrait project in 2014. This week he posted a special announcement on the web site of Bell Labs: Later this month, Bell Labs will celebrate the 50th anniversary of Unix with a special two day "Unix 50" event at their historic Murray Hill headquarters. This event should be one for the history books with many notable Unix and computer pioneers in attendance...! As I was making those photographs (which will be on display at the event), I gained much insight into Bell Labs and the development of Unix. However, it was some of the more personal stories and anecdotes that brought Bell Labs to life and gave me a feel for the people behind the code. One such time was when Ken Thompson (who is an accomplished pilot) told me how he traveled to Russia after the fall of the Soviet Union in order to fly in a MiG-29 fighter jet... Brian Kernighan told me about how a certain portrait of Peter Weinberger found its way into some very interesting places. These included the concrete foundation of a building on Bell Labs campus, the cover images printed onto Unix CD-ROMs, and most notably, painted on the top of a nearby water tower. Which brings us to another important piece of Unix mythology that I learned about: the fictitious Bell Labs employee G.R. Emlin (a.k.a. "the gremlin").... A lot of this folklore (including the gremlin) is going to be on display at the Unix 50 event. The archivists at Bell Labs have outdone themselves by pulling together a massive collection of artifacts taken from the labs where Unix was developed for over 30 years. I was able to photograph a few of these artifacts last year, but so much more will be exhibited at this event -- including several items from the personal archives of some attendees. As if that wasn't enough, the event will also showcase a number of vintage computers and a look into Bell Labs future with a tour of their Future X Labs. The article includes some more quick stories about the Unix pioneers at Bell Labs (including "the gremlin") and argues that "the decision to freely distribute Unix's source code (to anyone who asked for it) inadvertently set the stage for the free and open source software movements that dominate the technology industry today... "In hindsight, maybe 1969 should be called the 'summer of code.'"' -- source: https://tech.slashdot.org/story/19/10/12/1625237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

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

14 Oct '19

'More than a year has passed since Bloomberg Businessweek grabbed the lapels of the cybersecurity world with a bombshell claim: that Supermicro motherboards in servers used by major tech firms, including Apple and Amazon, had been stealthily implanted with a chip the size of a rice grain that allowed Chinese hackers to spy deep into those networks. Apple, Amazon, and Supermicro all vehemently denied the report. The National Security Agency dismissed it as a false alarm. The Defcon hacker conference awarded it two Pwnie Awards, for "most overhyped bug" and "most epic fail." And no follow-up reporting has yet affirmed its central premise. But even as the facts of that story remain unconfirmed, the security community has warned that the possibility of the supply chain attacks it describes is all too real. The NSA, after all, has been doing something like it for years, according to the leaks of whistle-blower Edward Snowden. Now researchers have gone further, showing just how easily and cheaply a tiny, tough-to-detect spy chip could be planted in a company's hardware supply chain. And one of them has demonstrated that it doesn't even require a state-sponsored spy agency to pull it off—just a motivated hardware hacker with the right access and as little as $200 worth of equipment.' -- source: https://arstechnica.com/information-technology/2019/10/planting-tiny-spy-ch… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

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

10 Oct '19

'System76, the Denver-based Linux PC manufacturer and developer of Pop OS, has some stellar news for those who prefer their laptops a little more open. Later this month the company will begin shipping two of their laptop models with its Coreboot-powered open source firmware. >From a report: Beginning today, System76 will start taking pre-orders for both the Galago Pro and Darter Pro laptops. The systems will ship out later in October, and include the company's Coreboot-based open source firmware which was previously teased at the 2019 Open Source Firmware Conference. (Coreboot, formerly known as LinuxBIOS, is a software project aimed at replacing proprietary firmware found in most computers with a lightweight firmware designed to perform only the minimum number of tasks necessary to load and run a modern 32-bit or 64-bit operating system.) What's so great about ripping out the proprietary firmware included in machines like this and replacing it with an open alternative? To begin with, it's leaner. System76 claims that users can boot from power off to the desktop 29% faster with its Coreboot-based firmware. [...] Both of these laptops can be kitted out with 10th-Generation Intel CPUs (specifically the i5-10210U and the i7-10510U), and both have glare-resistant matte 1080p IPS displays. Beginning at $949, the Galago Pro features an all-aluminum chassis, a wealth of connectivity options including HDMI, DisplayPort to USB-C and Thunderbolt, and can be configured with up to 32GB of RAM and up to 6TB of storage space. The Darter Pro, meanwhile, can be built out with 32GB of RAM and up to 2TB of storage, and features up to 10 hours of battery life.' -- source: https://hardware.slashdot.org/story/19/10/10/1847228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

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

'As one of the original versions of Unix, BSD is an ancient operating system. So it shouldn’t come as a surprise that it used what are, by today’s standards, strange, even ridiculous security. For one, the hashing function protecting passwords, though state of the art 40 years ago, is now trivial to crack. Stranger still, the password hashes of some BSD creators were included in publicly available source code. And then, there are the passwords people chose. Last week, technologist Leah Neukirchen reported finding a source tree for BSD version 3, circa 1980, and successfully cracking passwords of many of computing’s early pioneers. In most of the cases the success was the result of the users choosing easy-to-guess passwords. BSD co-inventor Dennis Ritchie, for instance, used “dmac” (his middle name was MacAlistair); Stephen R. Bourne, creator of the Bourne shell command line interpreter, chose “bourne”; Eric Schmidt, an early developer of Unix software and now the executive chairman of Google parent company Alphabet, relied on “wendy!!!” (the name of his wife); and Stuart Feldman, author of Unix automation tool make and the first Fortran compiler, used “axolotl” (the name of a Mexican salamander). Weakest of all was the password for Unix contributor Brian W. Kernighan: “/.,/.,”—representing a three-character string repeated twice using adjacent keys on a QWERTY keyboard. (None of the passwords included the quotation marks.) But there were at least five plaintext passwords that remained out of reach. They included those belonging to Turkish computer scientist Özalp Babaoğlu, Unix software developer Howard Katseff, and crucial Unix contributors Tom London and Bob Fabry. But the uncracked hash that seemed to occupy Neukirchen the longest was the password used by Ken Thompson, another Unix co-inventor. “I never managed to crack ken's password with the hash ZghOT0eRm4U9s, and I think I enumerated the whole 8 letter lowercase + special symbols key space,” Neukirchen reported in the above-linked thread, posted to the Unix Heritage Society mailing list. “Any help is welcome.' -- source: https://arstechnica.com/information-technology/2019/10/forum-cracks-the-vin… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A detailed look at Ubuntu’s new experimental ZFS installer
by Peter Reutemann 10 Oct '19

10 Oct '19

'Yesterday brought exciting news on the ZFS and Ubuntu fronts—experimental ZFS root support in the installer for Ubuntu's upcoming interim release, Eoan Ermine. The feature appeared in the 2019-10-09 daily build of Eoan—it's not in the regular beta release and, in fact, wasn't even in the "current daily" when we first went to download it. It's that new! (Readers wanting to play with the new functionality can find it in today's daily build, available here.)' -- source: https://arstechnica.com/information-technology/2019/10/a-detailed-look-at-u… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
