Mobile Spyware Maker mSpy Leaks Millions of Sensitive Records
by Peter Reutemann 05 Sep '18

05 Sep '18

'mSpy, the makers of a software-as-a-service product that claims to help more than a million paying customers spy on the mobile devices of their kids and partners, has leaked millions of sensitive records online, including passwords, call logs, text messages, contacts, notes and location data secretly collected from phones running the stealthy spyware. Krebs On Security reports: Less than a week ago, security researcher Nitish Shah directed KrebsOnSecurity to an open database on the Web that allowed anyone to query up-to-the-minute mSpy records for both customer transactions at mSpy's site and for mobile phone data collected by mSpy's software. The database required no authentication. Before it was taken offline sometime in the past 12 hours, the database contained millions of records, including the username, password and private encryption key of each mSpy customer who logged in to the mSpy site or purchased an mSpy license over the past six months. The private key would allow anyone to track and view details of a mobile device running the software, Shah said. In addition, the database included the Apple iCloud username and authentication token of mobile devices running mSpy, and what appear to be references to iCloud backup files. Anyone who stumbled upon this database also would have been able to browse the Whatsapp and Facebook messages uploaded from mobile devices equipped with mSpy. Other records exposed included the transaction details of all mSpy licenses purchased over the last six months, including customer name, email address, mailing address and amount paid. Also in the data set were mSpy user logs -- including the browser and Internet address information of people visiting the mSpy Web site.

MikroTik Routers Are Forwarding Owners' Traffic To Unknown Attackers
by Peter Reutemann 04 Sep '18

04 Sep '18

'Attackers have been exploiting vulnerabilities in MikroTik routers to forward network traffic to a handful of IP addresses under their control. "The bug is in Winbox management component and allows a remote attacker to bypass authentication and read arbitrary files," reports Bleeping Computer. "Exploit code is freely available from at least three sources from at least three sources." From the report: 360Netlab announced in a blog post today that more than 7,500 MikroTik routers across the world are currently delivering their TZSP (TaZmen Sniffer Protocol) traffic to nine external IP addresses. According to the researchers, the attacker modified the device's packet sniffing settings to forward the data to their locations. "37.1.207.114 is the top player among all the attackers. A significant number of devices have their traffic going to this destination," Qihoo experts inform. The analysis shows that the attacker is particularly interested in ports 20, 21, 25, 110, and 144, which are for FTP-data, FTP, SMTP, POP3, and IMAP traffic. An unusual interest is in traffic from SNMP (Simple Network Management Protocol) ports 161 and 162, which researchers cannot explain at the moment. The largest number of compromised devices, 1,628, is in Russia, followed by Iran (637), Brazil (615), India (594) and Ukraine (544). The researchers say that security outfits in the affected countries can contact them at netlab[at]360.cn for a full list of IPs.

How Do Spectre/Meltdown Fixes Affect The Linux Kernel?
by Peter Reutemann 01 Sep '18

01 Sep '18

'"Using the newly minted Linux 4.19 feature code, fresh benchmarks were carried out looking at the performance cost of Spectre/Meltdown/Foreshadow mitigations on Intel Xeon v. AMD EPYC CPUs," writes an anonymous Slashdot reader: Workloads affected by these CPU vulnerabilities mainly deal with I/O and frequent kernel calls while CPU bound tests are still found to be minimally impacted. When toggling these mitigations on Linux 4.19, Intel Xeon CPUs were found to be 10~15% slower with the default kernel while AMD EPYC CPUs dropped to about 5% slower.' -- source: https://linux.slashdot.org/story/18/09/01/1727238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Blocked Collaboration On Spectre/Meltdown Fixes, Says Linux Kernel Developer
by Peter Reutemann 01 Sep '18

01 Sep '18

'This week in Vancouver, Linux kernel developer Greg Kroah-Hartman criticized Intel's slow initial response to the Spectre and Meltdown bugs in a talk at the Open Source Summit North America. An anonymous reader quotes eWeek: Kroah-Hartman said that when Intel finally decided to tell Linux developers, the disclosure was siloed.... "Intel siloed SUSE, they siloed Red Hat, they siloed Canonical. They never told Oracle, and they wouldn't let us talk to each other." For an initial set of vulnerabilities, Kroah-Hartman said the different Linux vendors typically work together. However, in this case they ended up working on their own, and each came up with different solutions. "It really wasn't working, and a number of us kernel developers yelled at [Intel] and pleaded, and we finally got them to allow us to talk to each other the last week of December [2017]," he said. "All of our Christmas vacations were ruined. This was not good. Intel really messed up on this," Kroah-Hartman said... "The majority of the world runs Debian or they run their own kernel," Kroah-Hartman said. "Debian was not allowed to be part of the disclosure, so the majority of the world was caught with their pants down, and that's not good." To Intel's credit, Kroah-Hartman said that after Linux kernel developers complained loudly to the company in December 2017 and into January 2018, it fixed its disclosure process for future Meltdown- and Spectre-related vulnerabilities... "Intel has gotten better at this," he said. An interesting side effect of the Meltdown and Spectre vulnerabilities is that Linux and Windows developers are now working together, since both operating systems face similar risks from the CPU vulnerabilities. "Windows and Linux kernel developers now have this wonderful back channel. We're talking to each other and we're fixing bugs for each other," Kroah-Hartman said. "We are working well together. We have always wanted that."' -- source: https://it.slashdot.org/story/18/09/01/1736228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Android Bug Allows Geolocation Tracking of Users
by Peter Reutemann 30 Aug '18

30 Aug '18

'Researchers have discovered a weakness in all version of Android except 9, the most recent release, that can allow an attacker to gather sensitive information such as the MAC address and BSSID name and pinpoint the location of an affected device. The vulnerability is a result of the way that Android broadcasts device information to apps installed on a device. The operating system uses a mechanism known as an intent to send out information between processes or applications, and some of the information about the device's WiFi network interface sent via a pair of intents can be used by an attacker to track a device closely. A malicious app -- or just one that is listening for the right broadcasts from Android -- would be able to identify any individual Android device and geolocate it. An attacker could use this weaknesses to track a given device, presumably without the user's knowledge. Although Android has had MAC address randomization implemented since version 6, released in 2015, Yakov Shafranovich of Nightwatch Cybersecurity said his research showed that an attacker can get around this restriction.' -- source: https://yro.slashdot.org/story/18/08/30/1725225 Cheers, peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

What Dropbox Dropping Linux Support Says
by Peter Reutemann 29 Aug '18

29 Aug '18

'Jack Wallen, writing for TechRepublic: For a company to support Linux, they have to consider supporting: Multiple file systems, multiple distributions, multiple desktops, multiple init systems, multiple kernels. If you're an open source developer, focusing on a single distribution, that's not a problem. If you're a company that produces a product (and you stake your living on that product), those multiple points of entry do become a problem. Let's consider Adobe (and Photoshop). If Adobe wanted to port their industry-leading product to Linux, how do they do that? Do they spend the time developing support for ext4, btrfs, Ubuntu, Fedora, GNOME, Mate, KDE, systemd? You see how that might look from the eyes of any given company? It becomes even more complicated when companies consider how accustomed to the idea of "free" (as in beer) Linux users are. Although I am very willing to pay for software on Linux, it's a rare occasion that I do (mostly because I haven't found a piece of must-have software that has an associated cost). Few companies will support the Linux desktop when the act of supporting means putting that much time and effort into a product that a large cross-section of users might wind up unwilling to pay the price of admission. That's not to say every Linux user is unwilling to shell out the cost for a piece of software. But many won't.' -- source: https://linux.slashdot.org/story/18/08/29/0949228 Cheers, Peter -- Peter Reutemann Dept. 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 Linux Foundation Is Changing The Fabric Of Networking
by Peter Reutemann 29 Aug '18

29 Aug '18

'Will Townsend, a senior analyst at Moor Insights & Strategy research firm, writes: As it relates to networking, the Linux Foundation is currently focused on a number of projects that are bringing top networking vendors, operators, service providers, and users together. Among the top initiatives are the Open Network Automation Platform (ONAP) and Data Plane Development Kit (DPDK). In this article, I would like to dive into both of these initiatives and share my perspective on how each is transforming the nature of networking [Editor's note: the website may have auto-playing videos; an alternative link was not available]. It makes sense that ONAP's releases are named after global cities, considering the platform's growing global footprint. ONAP is aimed at bringing real-time automation and orchestration to both physical and virtualized network functions. The first release in the fall of 2017, named Amsterdam, delivered a unified architecture for providing closed-loop networking automation. The underlying framework ensured a level of modularity to facilitate future functionality as well as standards harmonization and critical upstream partner collaboration. Initial use cases centered on Voice Over LTE (VoLTE) services as well as Virtualized Consumer Premise Equipment (vCPE). Both are extremely cost disruptive from a deployment and management perspective and deliver enhanced service provider agility. What I find extremely compelling is that Amsterdam was only an eight-month development cycle from start to release. That's an amazing feat even in the fast-paced technology industry. [...] DPDK was an effort initially led by Intel at its inception nearly eight years ago, but became a part of the Linux Foundation back in 2017. At a high level, the technology accelerates packet processing workloads running on a variety of CPU architectures. DPDK is aimed at improving overall network performance, delivering enhanced encryption for improved security and optimizing lower latency applications that require lightning-fast response time. The transformative power of 5G networks lies in their potential to deliver low latency for applications such as augmented/virtual reality and self-driving cars -- DPDK will further extend that performance for next-generation wireless wide area networks. I had the opportunity recently to speak to project chair Jim St. Leger after the fifth DPDK release, and I was impressed with the depth and breadth of the open source project. Over 25 companies and 160 technologists are involved in advancing the effort. With the proliferation of data, cord cutting at home, and growing consumption of video over wired and wireless networks, high-quality compression techniques will dramatically improve performance and reliability. DPDK appears to be poised to contribute significantly to that effort.' -- source: https://linux.slashdot.org/story/18/08/29/1646231 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

WireGuard VPN review: A new type of VPN offers serious advantages
by Peter Reutemann 29 Aug '18

29 Aug '18

'WireGuard is a new type of VPN that aims to be simpler to set up and maintain than current VPNs and to offer a higher degree of security. The software is free and open source—it's licensed GPLv2, the same license as the Linux kernel—which is always a big plus in my book. It's also designed to be easily portable between operating systems. All of that might lead you to ask: in a world that already has IPSEC, PPTP, L2TP, OpenVPN, and a bewildering array of proprietary SSL VPNs, do we need yet another type of VPN?' -- source: https://arstechnica.com/gadgets/2018/08/wireguard-vpn-review-fast-connectio… Cheers, Peter -- Peter Reutemann Dept. 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 and CentOS Are Undoing a GNOME Security Feature
by Peter Reutemann 27 Aug '18

'Current versions of Ubuntu and CentOS are disabling a security feature that was added to the GNOME desktop environment last year. The feature's name is Bubblewrap, which is a sandbox environment that the GNOME Project added to secure GNOME's thumbnail parsers in July 2017, with the release of GNOME 3.26. In recent years, security researchers have proven that thumbnail parses can be an attack vector [1, 2, 3]. Ubuntu Security Tech Lead Alex Murray said the Ubuntu team chose to disable Bubblewrap inside Ubuntu because they did not have the time to perform a security audit. Murray blamed the many CPU bugs (Spectre, Meltdown, etc.), which kept the team busy and prevented them to audit the feature.' -- source: https://news.slashdot.org/story/18/08/27/1815234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Smartphones From 11 OEMs, Including Google, Samsung, HTC, Lenovo and Sony, Vulnerable To Attacks Via Hidden AT Commands
by Peter Reutemann 26 Aug '18

26 Aug '18

'In massive and groundbreaking research, a team of eleven scientists from the University of Florida, Stony Brook University, and Samsung Research America, have looked into what types of AT commands, or the Hayes command set, are currently supported on modern Android devices. The research team analyzed over 2,000 Android firmware images from eleven Android OEMs such as ASUS, Google, HTC, Huawei, Lenovo, LG, LineageOS, Motorola, Samsung, Sony, and ZTE. They say they discovered that these devices support over 3,500 different types of AT commands, some of which grant access to very dangerous functions. These AT commands are all exposed via the phone's USB interface, meaning an attacker would have to either gain access to a user's device, or hide a malicious component inside USB docks, chargers, or charging stations. Once an attacker is connected via the USB to a target's phone, s/he can use one of the phone's secret AT commands to rewrite device firmware, bypass Android security mechanisms, exfiltrate sensitive device information, perform screen unlocks, or even inject touch events solely through the use of AT commands.' -- source: https://mobile.slashdot.org/story/18/08/26/1910246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel's Reworked Microcode Security Fix License No Longer Prohibits Benchmarking
by Peter Reutemann 23 Aug '18

23 Aug '18

'Intel has backtracked on the license for its latest microcode update that mitigates security vulnerabilities in its processors -- after the previous wording outlawed public benchmarking of the chips. The reason for Intel's insistence on a vow of silence is that -- even with the new microcode in place -- turning off hyper-threading is necessary to protect virtual machines from attack via Foreshadow -- and that move comes with a potential performance hit. Predictably, Intel's contractual omerta had the opposite effect and drew attention to the problem. "Performance is so bad on the latest Spectre patch that Intel had to prohibit publishing benchmarks," said Lucas Holt, MidnightBSD project lead, via Twitter. In response to the outcry, Intel subsequently said it would rewrite the licensing terms. And now the fix is in. Via Twitter, Imad Sousou, corporate VP and general manager of Intel Open Source Technology Center, on Thursday said: "We have simplified the Intel license to make it easier to distribute CPU microcode updates and posted the new version here. As an active member of the open source community, we continue to welcome all feedback and thank the community." The reworked license no longer prohibits benchmarking. Long-time Slashdot reader and open-source pioneer, Bruce Perens, first brought Intel's microcode update to our attention. In a phone interview with The Register, Perens said he approved of the change. "This is a relatively innocuous license for proprietary software and it can be distributed in the non-free section of Debian, which is where is used to be, and it should be distributable by other Linux distributions," he said. "You can't expect every lawyer to understand CPUs. Sometimes they have to have a deep conversation with their technical people."' -- source: https://it.slashdot.org/story/18/08/23/2041206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Ghostscript Leaks Like A Sieve
by Lawrence D'Oliveiro 23 Aug '18

Tools like ImageMagick commonly accept graphics in PostScript format, which they render through Ghostscript. Trouble is, there are holes in Ghostscript that can be exploited by malicious parties. In short, you should not be accepting PostScript data from untrusted parties. The fact that PostScript is a full programming language just makes it harder -- in terms of vulnerability exposure, it’s similar to JavaScript, except that I think a lot more effort has gone into securing the latter. <https://www.theregister.co.uk/2018/08/23/imagemagick_ghostscript/>

Their problem is with the ban on chargers, because the school says they cannot provide outlets for 450 students. So laptops have to have a 5-hour battery life to make it through the exam. Which leaves out older machines with batteries in less-than-tiptop condition. Would there be a problem allowing them spare batteries? (And temporary use of an outlet while switching over, to avoid the need to power down?) Come to think of it, do they know they can buy spare batteries?

03 Aug '18

Security researchers often find themselves in for a rough ride (legally speaking) when they try to report holes that they have found. This new effort <https://arstechnica.com/information-technology/2018/08/new-open-source-effo…> tries to put together a clear framework so everybody knows exactly where they stand. Of course, the next step is to get various organizations to adopt it.

Reddit Breached Via Two-Factor Authentication Vulnerability
by Lawrence D'Oliveiro 02 Aug '18

02 Aug '18

Two-factor authentication, using a phone call or SMS text as the second factor, seemed like such a neat idea. But it turned out to be far too easy to hack. And here’s the proof <https://arstechnica.com/information-technology/2018/08/password-breach-teac…>: The 2FA protecting the Reddit accounts, however, relied on OTPs sent through SMS messages, despite reports over the years (such as this one <https://arstechnica.com/information-technology/2017/05/thieves-drain-2fa-pr…>) that make it amply clear they are susceptible to interception. Seems like the only reasonable option for a second authentication factor is dedicated hardware security keys.

sudo Or su?
by Lawrence D'Oliveiro 01 Aug '18

01 Aug '18

Found this piece <https://www.pclinuxos.com/forum/index.php/topic,90479.0.html> in the PCLinuxOS forums, courtesy of a reader link from <https://www.theregister.co.uk/2018/08/01/ncsc_ubuntu/>. Basically it says that “sudo”, when used “In The Manner Of the Buntus”, i.e. to be able to run arbitrary commands as root, is a bad idea. Instead, it should be carefully restricted to allow access only to functions needed by a particular user. To get blanket root access, it is better to use “su”, which means having a separate root password. Actually, it goes further than that: it decrees that anybody posting instructions on the PCLinuxOS forums involving “irresponsible” use of sudo (i.e. contrary to the philosophy above) is subject to having their posts deleted, being reprimanded, and ultimately having their account cancelled altogether. Thoughts?

Now They Need To Fix The TV Sets ...
by Lawrence D'Oliveiro 31 Jul '18

31 Jul '18

YouTube has adopted a more responsive page layout to cope with videos having different aspect ratios <https://arstechnica.com/gadgets/2018/07/youtube-picks-up-dark-mode-on-andro…>. To no-one’s surprise, this has annoyed a few people who have become accustomed to the old design. When 16:9 widescreen TVs were being conceived way back in the 1990s, the aim clearly was to allow us all to view cinematic movies full-screen, making maximum use of available screen area with minimal or no black bars. Nobody foresaw the widespread popularity of smartphones with built-in cameras, and of the common use of footage captured with such devices in TV broadcasts. But while such phones commonly have 16:9 screens and their cameras capture 16:9 footage, their users often hold them vertically, so the image ends up in just about the worst shape for display on a regular widescreen TV. There seems to be a common convention nowadays of filling in the gaps with blurred portions of the actual image -- which I agree looks less jarring than black bars. Hmmm ... there have been computer monitors that can be rotated to portrait or landscape orientations, with automatic adjustment of the display to match (aka “xrandr” <https://wiki.archlinux.org/index.php/xrandr>). Wouldn’t it be useful if a TV could do the same...?

Hi, A few days ago Ubuntu 18.04.01 was released for most flavours (e.g. Desktop, Server, Mate, Budgie, Kylin, Xubuntu, Kubuntu) You can get your flavour, in 32 or 64 bit, from here... https://www.ubuntu.com/download/desktop <https://www.ubuntu.com/download/desktop> http://cdimage.ubuntu.com/ubuntu/releases/18.04.1/release/ <http://cdimage.ubuntu.com/ubuntu/releases/18.04.1/release/> http://cdimage.ubuntu.com/ubuntu-mate/releases/18.04.1/release/ http://cdimage.ubuntu.com/ubuntu-budgie/releases/18.04.1/release/ http://cdimage.ubuntu.com/ubuntukylin/releases/18.04.1/release/ http://cdimage.ubuntu.com/xubuntu/releases/18.04.1/release/ http://cdimage.ubuntu.com/kubuntu/releases/18.04.1/release/ My understanding is that if you are running 16.04.xx LTS and you have enabled "Notify me of a new updated version of Ubuntu", then you should now start to get pop-up's prompting you to do an on-line update to 18.04.01. I'm hopeful that it will bring some stability to Mate that seemed to be lacking in 18.04.00. cheers, Ian.

Distrowatch review of Ubuntu MATE and Budgie 18.04
by Ian Young 30 Jul '18

30 Jul '18

This week's Distrowatch features Ubuntu MATE and Budgie for review. Not the usual reviewer and somewhat longer than most of the weekly distro reviews. Some faults found with the MATE version and to a lesser extent with Budgie. The laptop in use for testing only had 2GiB of RAM however which might account for some of the problems encountered. 4 GiB seems to be a bare minimum these days.

Intel Moving Away From Hyperthreading?
by Lawrence D'Oliveiro 27 Jul '18

27 Jul '18

Looks like Intel’s next-generation i7 product family will abandon hyperthreading in favour of increasing the core count. So while you will still be able to run 8 concurrent threads, each one gets its own core now. Also, it looks like Intel’s current fab technology is running out of steam, while the new one is a bit behind schedule. <https://arstechnica.com/gadgets/2018/07/leaked-benchmarks-show-intel-is-dro…>

Space Supercomputer Comes Up To First Birthday
by Lawrence D'Oliveiro 26 Jul '18

26 Jul '18

340 days ago, an HPE machine made up of two Apollo Intel x86 servers running RHEL was installed on the ISS, without any radiation hardening or any other special hardware adaptation measures, apart from a “water-cool enclosure”. So far it has suffered only two complete outages, both triggered by loss of external power, not the failure of the machine itself. Though the software has apparently been picking up transient memory errors (not too surprising, really). <https://www.theregister.co.uk/2018/07/26/hpe_iss_supercomputer/>

Bluetooth Security Flaw Could Let Nearby Attacker Grab Your Private Data
by Peter Reutemann 24 Jul '18

24 Jul '18

'A recently discovered bug in many Bluetooth firmware and OS drivers could allow an attacker within about 30 meters to capture and decrypt data shared between Bluetooth-paired devices. Researchers at the Israel Institute of Technology discovered the flaw, which was flagged today by Carnegie Mellon University CERT. It affects Bluetooth's Secure Simple Pairing and Low Energy Secure Connections. ZDNet reports: As the CERT notification explains, the vulnerability is caused by some vendors' Bluetooth implementations not properly validating the cryptographic key exchange when Bluetooth devices are pairing. The flaw slipped into the Bluetooth key exchange implementation which uses the elliptic-curve Diffie-Hellman (ECDH) key exchange to establish a secure connection over an insecure channel. This may allow a nearby but remote attacker to inject a a bogus public key to determine the session key during the public-private key exchange. They could then conduct a man-in-the-middle attack and "passively intercept and decrypt all device messages, and/or forge and inject malicious messages." Thankfully, patches are on the way. "Intel recommended users upgrade to the latest support driver and to check with vendors if they have provided one in their respective updates," reports ZDNet. "Dell has released a new driver for the Qualcomm driver it uses while Lenovo's update is for the flaw in Intel software. LG and Huawei have referenced fixes for CVE-2018-5383 in their respective July updates for mobile devices." It is not yet known if Android, Google, or the Linux kernel are affected. Apple has released a patch for the flaw earlier this month.' -- source: https://it.slashdot.org/story/18/07/24/2121215 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

ReactOS 0.4.9 Is Entirely Self-Hosting, Fixes FastFAT Crashes
by Peter Reutemann 24 Jul '18

24 Jul '18

'ReactOS, the "free Windows clone" operating system, has pushed out ReactOS 0.4.9 just recently, which brings a whole slew of improvements. With this latest 0.4.9 version, ReactOS has become entirely self-hosting without any issues, which means ReactOS can fully build itself from within itself, it does not require any third-party operating system to compile ReactOS. Self-hosting was built into older ReactOS versions, but it came with a myriad of issues -- the system would become too stressed under memory usage and storage I/O loads. This was due to a flawed NT-compliant kernel. Additional improvements in ReactOS 0.4.9 include overall stability and performance enhancements. The hardware abstraction layer and the FastFAT drivers received significant attention, and FastFAT should no longer eat through the cache so fast it causes system crashes due to resource leakage. FastFAT has also been rewritten to trigger a "chkdsk" repair on dirty / corrupt volumes during boot detections. Some other quality improvements are the addition of a built-in zipfldr extension -- ReactOS can now natively unpackage zipped archives, without the need of a third-party tool like WinZip.' -- source: https://news.slashdot.org/story/18/07/24/0139247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

In Encryption Push, Chrome Flags HTTP Sites as 'Not Secure'
by Peter Reutemann 24 Jul '18

24 Jul '18

'On Tuesday, Chrome started marking sites that don't use HTTPS as "not secure." From a report: First announced two years ago, Google said it would flag any site that still uses unencrypted HTTP to deliver its content in the latest version of Chrome, out Tuesday. It's part of the company's years-long effort effort to gradually nudge more webmasters and site owners into adopting HTTPS, a secure encryption standard for data in transit. Any site that doesn't load with green padlock or a "secure" message in the browser's address bar will be flagged -- and shamed -- as insecure. [...] According to nightly data compiled by security experts Troy Hunt and Scott Helme, roughly 100 of the top 500 websites are still serving their pages over unencrypted HTTP -- all of which will today be flagged as "insecure." Many of those sites -- like Baidu, JD.com, and Google.cn -- are Chinese language sites, but many popular Western sites -- including BBC.com, DailyMail.co.uk, and Fedex.com -- are HTTP. Of the top million sites, a little over half do not redirect to HTTPS. Chrome 68 also brings with it Page Lifecycle API, and the Payment Handler API. From a report: The Payment Handler API builds on the Payment Request API, which helped users check out online. The new API enables web-based payment apps to facilitate payments directly within the Payment Request experience, as seen above. As with every version, Chrome 68 includes an update to the V8 JavaScript engine: version 6.8. It reduces memory consumption as well as includes improvements to array destructuring, Object.assign, and TypedArray.prototype.sort. Check out the full list of changes for more information.' -- source: https://tech.slashdot.org/story/18/07/24/177207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Researchers Detail New CPU Side-Channel Attack Named SpectreRSB
by Peter Reutemann 24 Jul '18

24 Jul '18

'"Scientists from the University of California, Riverside (UCR) have published details last week about a new Spectre-class attack that they call SpectreRSB," reports Bleeping Computer. "Just like all 'Spectre-class' attacks, SpectreRSB takes advantage of the process of speculative execution -- a feature found in all modern CPUs that has the role of improving performance by computing operations in advance and later discarding unneeded data. The difference from previous Spectre-like attacks is that SpectreRSB recovers data from the speculative execution process by attacking a different CPU component involved in this 'speculation' routine, namely the Return Stack Buffer (RSB)." In a research paper, academics say they've used SpectreRSB attacks to recover data belonging to other processes, and have even tricked the RSB into spilling SGX secrets. The attack works on Intel, AMD, and ARM processors, known to use RSB. The attack can also bypass all the mitigations put in place for the original Spectre/Meltdown flaws.' -- source: https://it.slashdot.org/story/18/07/23/2143259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

None of Google's 85, 000 Employees Have Been Phished in More Than a Year After Company Required Them to Use Physical Security Keys For 2FA
by Peter Reutemann 24 Jul '18

24 Jul '18

'Google has not had any of its 85,000+ employees successfully phished on their work-related accounts since early 2017, when it began requiring all employees to use physical Security Keys in place of passwords and one-time codes, the company told KrebsOnSecurity. From the report: Security Keys are inexpensive USB-based devices that offer an alternative approach to two-factor authentication (2FA), which requires the user to log in to a Web site using something they know (the password) and something they have (e.g., a mobile device). A Google spokesperson said Security Keys now form the basis of all account access at Google. "We have had no reported or confirmed account takeovers since implementing security keys at Google," the spokesperson said. "Users might be asked to authenticate using their security key for many different apps/reasons. It all depends on the sensitivity of the app and the risk of the user at that point in time." The basic idea behind two-factor authentication is that even if thieves manage to phish or steal your password, they still cannot log in to your account unless they also hack or possess that second factor.' -- source: https://tech.slashdot.org/story/18/07/23/1944236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Academics Publish New Software-Level Protections Against Spectre and Rowhammer Attacks
by Peter Reutemann 23 Jul '18

23 Jul '18

'Academics from multiple universities have announced fixes for two severe security flaws known as Spectre and Rowhammer. Both these fixes are at the software level, meaning they don't require CPU or RAM vendors to alter products, and could, in theory, be applied as basic software patches. The first of these new mitigation mechanisms was announced on Thursday, last week. A research team from Dartmouth College in New Hampshire says it created a fix for Spectre Variant 1 (CVE-2017-5753), a vulnerability discovered at the start of the year affecting modern CPUs. Their fix uses ELFbac, an in-house-developed Linux kernel patch that brings access control policies to runtime virtual memory accesses of Linux processes, at the level of ELF binary executables. [...] The second fix for a major flaw announced last week came on Saturday from the Systems and Network Security Group at VU Amsterdam. Researchers announced a new technique called ZebRAM that they said is a comprehensive software protection against Rowhammer attacks.' -- source: https://it.slashdot.org/story/18/07/23/1613217 Cheers, Peter -- Peter Reutemann Dept. 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 Fifth Undocumented Cisco Backdoor Has Been Discovered
by Peter Reutemann 21 Jul '18

21 Jul '18

'Cisco released 25 security updates Wednesday, including a critical patch removing an undocumented password for "root" accounts of Cisco Policy Suite (sold to ISPs and large corporate clients). "The vulnerability received a rare severity score of 9.8 out of a maximum of 10 on the CVSSv3 scale," reports Bleeping Computer. An anonymous reader quotes Tom's Hardware: Over the past few months, not one, not two, but five different backdoors joined the list of security flaws in Cisco routers.... In March, a hardcoded account with the username "cisco" was revealed. The backdoor would have allowed attackers to access over 8.5 million Cisco routers and switches remotely. That same month, another hardcoded password was found for Cisco's Prime Collaboration Provisioning software, which is used for remote installation of Cisco's video and voice products. Later this May, Cisco found another undocumented backdoor account in Cisco's Digital Network Architecture Center, used by enterprises for the provisioning of devices across a network. In June, yet another backdoor account was found in Cisco's Wide Area Application Services, a software tool for Wide Area Network traffic optimization... Whether or not the backdoor accounts were created in error, Cisco will need to put an end to them before this lack of care for security starts to affect its business.' -- source: https://tech.slashdot.org/story/18/07/21/2133202 Cheers, Peter -- Peter Reutemann Dept. 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 Making the Windows Command Line a Lot Better
by Peter Reutemann 19 Jul '18

19 Jul '18

'Over the last few years, Microsoft has been working to improve the Windows console. Console windows now maximize properly, for example. In the olden days, hitting maximize would make the window taller but not wider. Today, the action will fill the whole screen, just like any other window. Especially motivated by the Windows subsystem for Linux, the console in Windows 10 supports 16 million colors and VT escape sequences, enabling much richer console output than has traditionally been possible on Windows. Microsoft is working to build a better console for Windows, one that we hope will open the door to the same flexibility and capabilities that Unix users have enjoyed for more than 40 years. The APIs seem to be in the latest Windows 10 Insider builds, though documentation is a little scarce for now. The command-line team is publishing a series of blog posts describing the history of the Windows command-line, and how the operating system's console works. The big reveal of the new API is coming soon, and with this, Windows should finally be able to have reliable, effective tabbed consoles, with emoji support, rich Unicode, and all the other things that the Windows console doesn't do... yet.' -- source: https://tech.slashdot.org/story/18/07/17/2028206 It's probably gonna get announced as "revolutionary"...

PC Sales Grow For A Change
by Lawrence D'Oliveiro 13 Jul '18

13 Jul '18

The first year-on-year growth in quarterly PC shipments has happened in 6 years <https://arstechnica.com/gadgets/2018/07/pc-market-appears-to-have-grown-for…>. Interesting to compare the basis behind the two different figures quoted: excluding Chromebooks, but including tablets (whether running Windows or not), gives a figure of 1.4% increase (Gartner), while the converse gives 2.7% (IDC). In other words, Chromebooks are accounting for something like half that growth, possibly even more.

Python Creator Steps Down
by Lawrence D'Oliveiro 13 Jul '18

13 Jul '18

Guido van Rossum, creator of Python and (up to now) “Benevolent Dictator For Life” over the Python project, has decided to relinquish that role <https://www.theregister.co.uk/2018/07/13/python_creator_guido_van_rossum_qu…>. The reason may have been building for a while, but the last straw seems to have been the controversy over this <https://www.python.org/dev/peps/pep-0572/> proposed new feature for Python, “assignment expressions”, using a new “:=” operator. Interestingly enough, back in the day, “:=” was the operator used for assignments in what they called “ALGOL-like” languages (which included Pascal). The use of “=” for assignment was a peculiarity of FORTRAN, and also adopted by C, from which it has spread (unfortunately, in my view) to be adopted in most newer, higher-level languages, like Perl and Python. In the “ALGOL-like” languages, “=” kept close to its mathematical meaning, namely a test for equality. But if “:=” becomes valid, how long before these “assignment expressions” become acceptable stand-alone, as assignment statements? Pity that “=” can never become the equality-test operator ... unless Python 4 provides some way to guard against writing expressions as statements that simply discard their value ...

AV1 is Well On Its Way To Becoming a Viable Alternative To Patented Video Codecs, Mozilla Says
by Peter Reutemann 12 Jul '18

12 Jul '18

'Here's a surprising fact: It costs money to watch video online, even on free sites like YouTube. That's because about 4 in 5 videos on the web today rely on a patented technology called the H.264 video codec. >From a report: It took years for companies to put this complex, global set of legal and business agreements in place, so H.264 web video works everywhere. Now, as the industry shifts to using more efficient video codecs, those businesses are picking and choosing which next-generation technologies they will support. The fragmentation in the market is raising concerns about whether our favorite web past-time, watching videos, will continue to be accessible and affordable to all. Over the last decade, several companies started building viable alternatives to patented video codecs. Mozilla worked on the Daala Project, Google released VP9, and Cisco created Thor for low-complexity videoconferencing. All these efforts had the same goal: to create a next-generation video compression technology that would make sharing high-quality video over the internet faster, more reliable, and less expensive. In 2015, Mozilla, Google, Cisco, and others joined with Amazon and Netflix and hardware vendors AMD, ARM, Intel, and NVIDIA to form AOMedia. As AOMedia grew, efforts to create an open video format coalesced around a new codec: AV1. AV1 is based largely on Google's VP9 code and incorporates tools and technologies from Daala, Thor, and VP10. Mozilla loves AV1 for two reasons: AV1 is royalty-free, so anyone can use it free of charge. Software companies can use it to build video streaming into their applications. Web developers can build their own video players for their sites. The second reason we love AV1 is that it delivers better compression technology than even high-efficiency codecs -- about 30% better, according to a Moscow State University study.' -- source: https://news.slashdot.org/story/18/07/11/2246221 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Now, I read today in the Hamilton Press (issue of 11th July, i.e. today), on page 6, that the affected customers include the Hamilton City Council, Waikato District Council, and Waipā District Council. “About 2800 Waikato people” may have used the Typeform service to express views to these local bodies. Information that could have been leaked was “names, email addresses, and in some cases, phone numbers”. Hamilton City used the service to run 10 surveys between November 2014 and February 2018, and a total of 1941 people “may have been affected”; it has contacted them about the breach, and it doesn’t use Typeform any more. Waipā District has similarly contacted 125 participants in its surveys. (No mention of what action Waikato District is taking...)

Year-old router bug exploited to steal sensitive DOD drone, tank documents
by Peter Reutemann 11 Jul '18

11 Jul '18

'In May, a hacker perusing vulnerable systems with the Shodan search engine found a Netgear router with a known vulnerability—and came away with the contents of a US Air Force captain's computer. The purloined files from the captain—the officer in charge (OIC) of the 432d Aircraft Maintenance Squadron's MQ-9 Reaper Aircraft Maintenance Unit (AMU)at Creech Air Force Base, Nevada—included export-controlled information regarding Reaper drone maintenance. The hacker took the documents to a Dark Web marketplace, where he planned on selling them for a few hundred dollars. And it's there that analysts from Recorded Future, an information security threat intelligence company, discovered them. The vulnerability, which makes it possible for an attacker to remotely execute commands and gain access to the root directory of the router via FTP, was disclosed by Netgear over a year ago. Discoverable by searching Shodan for devices with Internet Protocol port 21 open and response text including "214-ADMIN_LOGIN," the vulnerability allowed attackers to compromise routers and then gain access to the local network. They could then either grab files passing over the network or gain access to devices on it.' -- source: https://arstechnica.com/information-technology/2018/07/year-old-router-bug-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Malware Found in Arch Linux AUR Package Repository
by Peter Reutemann 11 Jul '18

11 Jul '18

'Malware has been discovered in at least three Arch Linux packages available on AUR (Arch User Repository), the official Arch Linux repository of user-submitted packages. The malicious code has been removed thanks to the quick intervention of the AUR team. The incident happened because AUR allows anyone to take over "orphaned" repositories that have been abandoned by their original authors. On Saturday, a user going by the pseudonym of "xeactor" took over one such orphaned package named "acroread" that allows Arch Linux users to view PDF files. According to a Git commit to the packag's source code, xeactor added malicious code that would download a file named "~x" from ptpb [dot] pw, a lightweight site mimicking Pastebin that allows users to share small pieces of texts.' -- source: https://it.slashdot.org/story/18/07/10/2136251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Stolen certificates from D-Link used to sign password-stealing malware
by Peter Reutemann 10 Jul '18

10 Jul '18

'Criminals recently stole code-signing certificates from router and camera maker D-Link and another Taiwanese company and used them to pass off malware that steals passwords and backdoors PCs, a researcher said Monday. The certificates were used to cryptographically verify that legitimate software was issued by D-Link and Changing Information Technology. Microsoft Windows, Apple’s macOS, and most other operating systems rely on the cryptographic signatures produced by such certificates to help users ensure that executable files attached to emails or downloaded on websites were developed by trusted companies rather than malicious actors masquerading as those trusted companies. Somehow, members of an advanced persistent-threat hacking group known as BlackTech obtained the certificates belonging to D-Link and Changing Information Technology, the researcher with antivirus provider Eset said in a blog post. The attackers then used the certificates to sign two pieces of malware, one a remotely controlled backdoor and the other a related password stealer. Both pieces of malware are referred to as Plead and are used in espionage campaigns against targets located in East Asia. The Japan Computer Emergency Response team recently documented the Plead malware here. AV provider Trend Micro recently wrote about BlackTech here. “The ability to compromise several Taiwan-based technology companies and reuse their code-signing certificates in future attacks shows that this group is highly skilled and focused on that region,” Eset researcher Anton Cherepanov wrote in Monday’s post.' -- source: https://arstechnica.com/information-technology/2018/07/stolen-certificates-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New Spectre-like attack uses speculative execution to overflow buffers
by Peter Reutemann 10 Jul '18

'When the Spectre and Meltdown attacks were disclosed earlier this year, the expectation was that these attacks would be the first of many, as researchers took a closer look at the way that the speculative execution in modern processors could be used to leak sensitive information and undermine the security of software running on those processors.

With So Many Eyeballs, Is Open Source Security Better?
by Peter Reutemann 10 Jul '18

10 Jul '18

'Back in 1999, Eric Raymond coined the term "Linus' Law," which stipulates that given enough eyeballs, all bugs are shallow. Linus' Law, named in honor of Linux creator Linus Torvalds, has for nearly two decades been used by some as a doctrine to explain why open source software should have better security. In recent years, open source projects and code have experienced multiple security issues, but does that mean Linus' Law isn't valid? According to Dirk Hohndel, VP and Chief Open Source Officer at VMware, Linus' Law still works, but there are larger software development issues that impact both open source as well as closed source code that are of equal or greater importance. "I think that in every development model, security is always a challenge," Hohndel said. Hohndel said developers are typically motivated by innovation and figuring out how to make something work, and security isn't always the priority that it should be. "I think security is not something we should think of as an open source versus closed source concept, but as an industry," Hohndel said.' -- source: https://it.slashdot.org/story/18/07/10/1642226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox and Chrome Pull Popular Browser Extension Stylish From Their Stores After Report Claimed It Logs and Shares Browsing History, Credentials
by Peter Reutemann 05 Jul '18

05 Jul '18

'Stylish, a popular extension available for Chrome and Firefox which allows for easy customization of any website, now phones home and shares its users' browser history with its corporate parent, according to blogger Robert Heaton. This prompted Firefox to ban the extension from its addons site and prompt all users to disable it. The discussion can be seen in the relevant bug report. In Heaton's words: Stylish is no longer a well-meaning product with your best interests at heart. If you use and like Stylish, please uninstall it and switch to an alternative like Stylus, an offshoot from the good old version of Stylish that works in much the same way, minus the spyware. Google too has pulled the extension from its extension store.

Download Bomb Trick Returns in Chrome -- Also Affects Firefox, Opera, Vivaldi and Brave
by Peter Reutemann 03 Jul '18

03 Jul '18

'The release of Google Chrome 67 has reopened a "download bomb" bug that was exploited by tech support scammers last winter, and which had been fixed with the release of Chrome 65 in March 2018. Furthermore, the issue also appears to affect other browsers as well, such as Firefox, Vilvadi, Opera, and Brave, according to tests carried out by Bleeping Computer. The "download bomb" trick is a technique that involves initiating hundreds or thousands of downloads to freeze a browser on a specific page. Across the years, there have been multiple variations of download bombs, and they have often been used by tech support scammers to trap users on shady sites that tried to lure victims into calling a tech support number to have their browser unlocked. Over the winter, security researchers from Malwarebytes noticed a tech support scam campaign that employed a new "download bomb" technique to trap users on its shady sites.' -- source: https://news.slashdot.org/story/18/07/03/1416208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Study Finds That a Large Number of Popular Android Apps Secretly Cast the Screen To Third Parties, But They Don't Listen To Conversations
by Peter Reutemann 03 Jul '18

03 Jul '18

'It's the smartphone conspiracy theory that just won't go away: Many, many people are convinced that their phones are listening to their conversations to target them with ads. [...] Some computer science academics at Northeastern University had heard enough people talking about this technological myth that they decided to do a rigorous study to tackle it. For the last year, Elleen Pan, Jingjing Ren, Martina Lindorfer, Christo Wilson, and David Choffnes ran an experiment involving more than 17,000 of the most popular apps on Android to find out whether any of them were secretly using the phone's mic to capture audio. The apps included those belonging to Facebook, as well as over 8,000 apps that send information to Facebook. Sorry, conspiracy theorists: They found no evidence of an app unexpectedly activating the microphone or sending audio out when not prompted to do so. Like good scientists, they refuse to say that their study definitively proves that your phone isn't secretly listening to you, but they didn't find a single instance of it happening. Instead, they discovered a different disturbing practice: apps recording a phone's screen and sending that information out to third parties.' -- source: https://yro.slashdot.org/story/18/07/03/1822250 Cheers, Peter -- Peter Reutemann Dept. 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 Allows Outside App Developers To Read People's Gmails, Says Report
by Peter Reutemann 03 Jul '18

03 Jul '18

'According to The Wall Street Journal, hundreds of app developers have access to millions of inboxes belonging to Gmail users (Warning: source paywalled; alternative source). The developers reportedly receive access to messages from Gmail users who signed up for things like price-comparison services or automated travel-itinerary planners. Some of these companies train software to scan the email, while others enable their workers to pore over private messages. INSIDER reports: It's not news that Google and many top email providers enable outside developers to access users' inboxes. In most cases, the people who signed up for the price-comparison deals or other programs agreed to provide access to their inboxes as part of the opt-in process. In Google's case, outside developers must pass a vetting process, and as part of that, Google ensures they have an acceptable privacy agreement, The Journal reported, citing a Google representative. What is unclear is how closely these outside developers adhere to their agreements and whether Google does anything to ensure they do, as well as whether Gmail users are fully aware that individual employees may be reading their emails, as opposed to an automated system, the report says. It's interesting to note that, judging from The Journal's story, very little indicates that Google is doing anything different from Microsoft or other top email providers. According to the newspaper, nothing in Microsoft or Yahoo's policy agreements explicitly allows people to read others' emails.

Metric-Compatible Fonts
by Lawrence D'Oliveiro 02 Jul '18

02 Jul '18

I was idly doing some web searches the other day (as you do), and stumbled across this page <https://wiki.archlinux.org/index.php/Metric-compatible_fonts> at the ever-dependable Arch Wiki. My specific question was, what had happened to the “URW Palladio” font? Up until recently, this was the one that Fontconfig would offer up when I used the old “Palatino” name from Adobe PostScript days. (I used to like the way the curve of the “P” didn’t quite join up with the stem, but left a little gap with a pointy bit on the end. Ahem...) Turns out it’s still there, just under another name; it’s now called “P052” for some unfathomable reason. Anyway, that page gives a bunch of handy alternatives if you are looking for Free alternatives to proprietary fonts that preserve the metrics (widths, spacing etc), so substituting them won’t stuff up the formatting of a document.

'Why You Should Not Use Google Cloud'
by Peter Reutemann 02 Jul '18

02 Jul '18

'A user on Medium named "Punch a Server" says you should not use Google Cloud due to the "'no-warnings-given, abrupt way' they pull the plug on your entire system if they (or the machines) believe something is wrong." The user has a project running in production on Google Cloud (GCP) that is used to monitor hundreds of wind turbines and scores of solar plants scattered across 8 countries. When their project goes down, money is lost. An anonymous Slashdot reader shares the report: Early today morning (June 28, 2018) I receive an alert from Uptime Robot telling me my entire site is down. I receive a barrage of emails from Google saying there is some "potential suspicious activity" and all my systems have been turned off. EVERYTHING IS OFF. THE MACHINE HAS PULLED THE PLUG WITH NO WARNING. The site is down, app engine, databases are unreachable, multiple Firebases say I've been downgraded and therefore exceeded limits. Customer service chat is off. There's no phone to call. I have an email asking me to fill in a form and upload a picture of the credit card and a government issued photo id of the card holder. Great, let's wake up the CFO who happens to be the card holder. What if the card holder is on leave and is unreachable for three days? We would have lost everything -- years of work -- millions of dollars in lost revenue. I fill in the form with the details and thankfully within 20 minutes all the services started coming alive. The first time this happened, we were down for a few hours. In all we lost everything for about an hour. An automated email arrives apologizing for "inconvenience" caused.

Massive New 'Salesforce Tower' Light Sculpture: AI, Ubuntu, Fog, and a MacBook
by Peter Reutemann 30 Jun '18

30 Jun '18

'The new tallest building on the San Francisco skyline -- and the tallest building in America west of the Mississippi -- includes a nine-story electronic sculpture that's been called the tallest piece of public art on Earth. It uses 11,000 LED bulbs reflected off the tower-topping aluminum panels -- each pixel created by a set of red, green, blue and white lights controlled by 8-bit PIC microcontrollers. "On a clear night, the show is visible for 30 miles," reports IEEE Spectrum. Slashdot reader Tekla Perry shares their article about "the technology involved in the light show at the top of Salesforce Tower. Electrical engineer and artist Jim Campbell explains it all -- and how the window-washer problem stumped him for nearly a year." "[O]n the 62nd floor, a central PC-based computer runs Ubuntu Linux, sending instructions to a communications control system that splits the data and sends it at 11 Mbit to the 32 enclosures using a custom communications protocol... We will capture images throughout the day, sending them to Amazon's cloud, and run some algorithms designed to identify visual interesting-ness. For example, at its simplest, when we look at the sky, if it's all blue, it's boring, if it's all white, it's boring, if it has white and blue it is likely to be interesting. We'll chose the best half hour of the day at each camera, based on movement and color, to display...." And finally, when the main display shuts down late at night, another system designed by Campbell will kick in. In this static display, a set of 36 white LEDs will create a three-dimensional constellation of lights that will look like stars. "It's quieter, it has a random aspect to it," he says. "Since construction started, the tower has emerged as an icon of the new San Francisco -- techie, ambitious, perhaps a little grandiose," writes the New Yorker, capturing the moment when Campbell finally unveiled his four-year project -- while fighting stomach flu and a chest cold, on a night which turned out to be prohibitively foggy. The executive vice-president of Boston Properties told him cheerily, "Jim! Look on the brighter side. We've got every night for the rest of our lives." "There was a long silence from the people on the terrace. The fog was thick. At last, someone exclaimed, 'Woo-hoo!,' and a volley of cheers followed." Although the colors they were seeing came from the celebratory fireworks and not from Jim's light sculpture. Are there any San Francisco-area Slashdotters who want to weigh in on the Salesforce Tower?' -- source: https://tech.slashdot.org/story/18/06/30/2031224 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

It’s Not A Bug, It’s A Feature!
by Lawrence D'Oliveiro 30 Jun '18

30 Jun '18

The IndexByDate.txt files available on the various Bitsavers directories (e.g. <http://bitsavers.trailing-edge.com/pdf/>) list the various items available in order of date. But if you want them ordered by name, so items in the same directory come together, the logical thing to do is use the sort(1) <https://linux.die.net/man/1/sort> command on this file. You specify the sort key by a “field definition”. The man page says that, by default, each field starts at a non-whitespace character after whitespace. The file has a very regular format: splitting by whitespace, you get the date, the time, and then the pathname. So a command like sort -k3 IndexByDate.txt should work. Except I was seeing a sequence like this: 2006-08-17 22:17:12 ge/MarkI_Timesharing/IPC-202646_FORTRAN_Aug66.pdf 2012-08-29 02:26:21 generalAutomation/18_30/88A00026A-A_GA1830_Industrial_Supervisory_System_Reference_Manual_May69.pdf ... 2018-05-16 00:33:35 georgiaTech/GTL_Programmers_Reference_Manual_for_the_Burroughs_B_5500_Aug1974.pdf 2006-08-27 11:36:57 ge/PAC-4000/GET-3201B_PAC-4000_SysMan_Mar66.pdf As you can see, the “ge” section is interrupted by “generalAutomation” and others, and then resumes after them. What was going on? It took me a while to realize that the sorting is done by locale, and the locale setting is set to ignore the slashes. Thus, the above sequence is effectively “gem” followed by “gen”, then “geo” and “gep”. What I wanted was a straight ASCII sort on the full pathname, without regard to any locale settings. But there is no hint in the man page as to how to specify this. Then I realized: the locale is controlled by environment variables. If you want the “non-localized” locale, then specify the locale called “C”, thus: LC_ALL=C sort -k3 IndexByDate.txt and this gives the order I want.

Writing for BetaNews, Brian Fagioli: The most significant aspect of Linux Mint 19 is the new Ubuntu 18.04 LTS base. Tara will receive updates until 2023 -- very impressive. The kernel is at 4.15, and all three desktop environments are being updated too. Mate is now at version 1.2, Cinnamon gets bumped up to 3.8, and Xfce is updated to 4.12. In Linux Mint 19, the star of the show is Timeshift, said, Clement Lefebvre, Linux Mint Project Leader. Although it was introduced in Linux Mint 18.3 and backported to all Linux Mint releases, it is now at the center of Linux Mint's update strategy and communication, he added. Thanks to Timeshift you can go back in time and restore your computer to the last functional system snapshot. If anything breaks, you can go back to the previous snapshot and it's as if the problem never happened.' -- source: https://linux.slashdot.org/story/18/06/29/2041255 Cheers, Petre -- Peter Reutemann Dept. 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 Invests $22 Million In Feature Phone Operating System KaiOS
by Peter Reutemann 30 Jun '18

30 Jun '18

'Google is turning startup investor to further its goal of putting Google services like search, maps, and its voice assistant front and center for the next billion internet users in emerging markets. It has invested $22 million into KaiOS, the company that has built an eponymous operating system for feature phones that packs a range of native apps and other smartphone-like services. As part of the investment, KaiOS will be working on integrating Google services like search, maps, YouTube and its voice assistant into more KaiOS devices, after initially announcing Google apps for KaiOS-powered Nokia phones earlier this year. KaiOS is a U.S.-based project that started in 2017, built on the ashes of Mozilla's failed Firefox OS experiment, as a fork of the Linux codebase. Firefox OS was intended to be the basis of a new wave of HTML-5, low-cost smartphones. And while those devices and the wider ecosystem never really took off, KaiOS has fared significantly better. KaiOS powers phones made by OEMs including Nokia (HMD), Micromax and Alcatel, and it works with carriers including Sprint and AT&T -- it counts offices in North America, Europe and Asia. But its most significant deployment to date has been with India's Reliance Jio, the challenger telco that disrupted the Indian market with affordable 4G data packages. "This funding will help us fast-track development and global deployment of KaiOS-enabled smart feature phones, allowing us to connect the vast population that still cannot access the internet, especially in emerging markets," said KaiOS CEO Sebastien Codeville in a statement.' -- source: https://mobile.slashdot.org/story/18/06/29/2118251 Cheers, Peter -- Peter Reutemann Dept. 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, Google, and Microsoft Use Design To Trick You Into Handing Over Your Data, Report Warns
by Peter Reutemann 29 Jun '18

29 Jun '18

'A study from the Norwegian Consumer Council dug into the underhanded tactics used by Microsoft, Facebook, and Google to collect user data. "The findings include privacy intrusive default settings, misleading wording, giving users an illusion of control, hiding away privacy-friendly choices, take-it-or-leave-it choices, and choice architectures where choosing the privacy friendly option requires more effort for the users," states the report, which includes images and examples of confusing design choices and strangely worded statements involving the collection and use of personal data. Google makes opting out of personalized ads more of a chore than it needs to be and uses multiple pages of text, unclear design language, and, as described by the report, "hidden defaults" to push users toward the company's desired action. "If the user tried to turn the setting off, a popup window appeared explaining what happens if Ads Personalization is turned off, and asked users to reaffirm their choice," the report explained. "There was no explanation about the possible benefits of turning off Ads Personalization, or negative sides of leaving it turned on." Those who wish to completely avoid personalized ads must traverse multiple menus, making that "I agree" option seem like the lesser of two evils. In Windows 10, if a user wants to opt out of "tailored experiences with diagnostic data," they have to click a dimmed lightbulb, while the symbol for opting in is a brightly shining bulb, says the report. Another example has to do with Facebook. The social media site makes the "Agree and continue" option much more appealing and less intimidating than the grey "Manage Data Settings" option. The report says the company-suggested option is the easiest to use. "This 'easy road' consisted of four clicks to get through the process, which entailed accepting personalized ads from third parties and the use of face recognition. In contrast, users who wanted to limit data collection and use had to go through 13 clicks."' -- source: https://tech.slashdot.org/story/18/06/27/2233234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

What's Up With ProtonMail Outages?
by Peter Reutemann 28 Jun '18

28 Jun '18

Since we talked about ProtonMail in the past... 'ProtonMail, a secure email service provider used by more than two million users and references of which has been made in shows like Mr. Robot, has been facing outages for the last two days as it fights numerous DDoS attacks. "The attacks went on for several hours, although the outages were far more brief, usually several minutes at a time with the longest outage on the order of 10 minutes," a ProtonMail spokesperson told BleepingComputer, adding that it has tracked the attack to a group that claims to have ties to Russia. But things are more complicated than that, and it appears ProtonMail users, who are already annoyed at the frequent outages over the last few days, are up for more such downtimes in the coming days. BleepingComputer: But in reality, the DDoS attacks have no ties to Russia, weren't even planned to in the first place, and the group behind the attacks denounced being Russian, to begin with. Responsible for the attacks is a hacker group named Apophis Squad. In a private conversation with Bleeping Computer today, one of the group's members detailed yesterday's chain of events. The Apophis member says they targeted ProtonMail at random while testing a beta version of a DDoS booter service the group is developing and preparing to launch. The group didn't cite any reason outside "testing" for the initial and uncalled for attack on ProtonMail, which they later revealed to have been a 200 Gbps SSDP flood, according to one of their tweets. "After we sent the first attack, we downed it for 60 seconds," an Apophis Squad member told us. He said the group didn't intend to harass ProtonMail all day yesterday or today but decided to do so after ProtonMail's CTO, Bart Butler, responded to one of their tweets calling the group "clowns." This was a questionable response on the part of the ProtonMail CTO, as it set the hackers against his company even more. "So we then downed them for a few hours," the Apophis Squad said. Subsequent attacks included a whopping TCP-SYN flood estimated at 500 Gbps, as claimed by the group.' -- source: https://it.slashdot.org/story/18/06/28/159252 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Every Android Device Launched Since 2012 Impacted By RAMpage Vulnerability
by Peter Reutemann 28 Jun '18

28 Jun '18

'Almost all Android devices released since 2012 are vulnerable to RAMpage bug, an international team of academics has revealed today. >From a report: The vulnerability, tracked as CVE-2018-9442, is a variation of the Rowhammer attack. Rowhammer is a hardware bug in modern memory cards. A few years back researchers discovered that when someone would send repeated write/read requests to the same row of memory cells, the write/read operations would create an electrical field that would alter data stored on nearby memory. In the following years, researchers discovered that Rowhammer-like attacks affected personal computers, virtual machines, and Android devices. Through further researcher, they also found they could execute Rowhammer attacks via JavaScript code, GPU cards, and network packets.' -- source: https://it.slashdot.org/story/18/06/28/160220 Cheers, Peter -- Peter Reutemann Dept. 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 Doubles Down on Linux and Open Source

'Google couldn't exist without Linux and open-source software. While you may not think of Google as a Linux company in the same way as you do Canonical, Red Hat, or SUSE, it wouldn't be the search and advertising giant it is today without Linux. So, it makes sense that Google is moving up from its Silver membership in The Linux Foundation, to the Platinum level. With this jump in status, Google gets a seat on the Foundation's board of directors. This position will be filled by Sarah Novotny, the head of open source strategy for Google Cloud Platform.

'A slice of computing history has been made public, giving people the opportunity to delve into an archive that inspired a generation of coders. The Computer Literacy Project led to the introduction of the BBC Micro alongside programs which introduced viewers to the principles of computing. It included interviews with innovators such as Bill Gates and Steve Wozniak. The BBC hopes the 1980s archive will encourage today's youngsters to become involved in computing. With the release of the archive, viewers can now search and browse all of the programmes from the project.

Anonymizing Printed Documents
by Lawrence D'Oliveiro 27 Jun '18

27 Jun '18

It’s been known for a while that many printer vendors add extra hard-to-detect dots to their printouts to make a pattern that can be used to identify the source of the document later. Now a research group <http://www.theregister.co.uk/2018/06/27/german_researchers_defeat_printer_t…> has found a way to stymie this process by adding extra dots that fit the patterns, but confuse the identification system. They even have source code on GitHub.

OpenBSD Chief De Raadt Says No Easy Fix For New Intel CPU Bug 'TLBleed'
by Peter Reutemann 26 Jun '18

26 Jun '18

'Recompiling is unlikely to be a catch-all solution for a recently unveiled Intel CPU vulnerability known as TLBleed, the details of which were leaked on Friday, the head of the OpenBSD project Theo de Raadt says. iTWire reports: The details of TLBleed, which gets its name from the fact that the flaw targets the translation lookaside buffer, a CPU cache, were leaked to the British tech site, The Register; the side-channel vulnerability can be theoretically exploited to extract encryption keys and private information from programs. Former NSA hacker Jake Williams said on Twitter that a fix would probably need changes to the core operating system and were likely to involve "a ton of work to mitigate (mostly app recompile)." But de Raadt was not so sanguine. "There are people saying you can change the kernel's process scheduler," he told iTWire on Monday. "(It's) not so easy." He said that Williams was lacking all the details and not thinking it through. "They actually have sufficient detail to think it through: the article says the TLB is shared between hyperthreading CPUs, and it is unsafe to share between two different contexts. Basically you can measure evictions against your own mappings, which indicates the other process is touching memory (you can determine the aliasing factors)." De Raadt said he was still not prepared to say more, saying: "Please wait for the paper [which is due in August]."' -- source: https://it.slashdot.org/story/18/06/25/2219217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Likely NSA Data-Collection Facilities
by Lawrence D'Oliveiro 26 Jun '18

26 Jun '18

Further to the mention last night of secret facilities operated by AT&T in the US where the NSA has access, this article <https://arstechnica.com/tech-policy/2018/06/meet-the-8-spooky-att-buildings…> reports on a list of eight likely places as detailed by The Intercept <https://theintercept.com/2018/06/25/att-internet-nsa-spy-hubs/>. While the NSA is not technically allowed to spy on wholly “domestic” communications, there seem to be no limits on any “incidental collection” as a result of targetting some foreign communication. That means they can grab the contents of entire mailboxes just for the sake of one message. Then keep the lot for whatever use they like.

How Should Open Source Development Be Subsidized?
by Peter Reutemann 24 Jun '18

24 Jun '18

'"Open source maintainers are exhausted and rarely paid," writes TechCrunch's editorial manager. "A new generation wants to change the economics." An anonymous reader quotes their report: [Patreon] is increasingly being used by notable open source contributors as a way to connect with fans and sustain their work... For those who hit it big, the revenues can be outsized. Evan You, who created the popular JavaScript frontend library Vue.js, has reached $15,206 in monthly earnings ($182,472 a year) from 231 patrons... While Patreon is one direct approach for generating revenues from users, another one is to offer dual licenses, one free and one commercial... Companies care about proper licensing, and that becomes the leverage to gain revenue while still maintaining the openness and spirit of open source software... Tidelift is designed to offer assurances "around areas like security, licensing, and maintenance of software," CEO Donald Fischer explained... In addition, Tidelift handles the mundane tasks of setting up open source for commercialization such as handling licensing issues... Open Collective wants to open source the monetization of open source itself. Open Collective is a non-profit platform that provides tools to "collectives" to receive money while also offering mechanisms to allow the members of those collectives to spend their money in a democratic and transparent way. TechCrunch warns that "It's not just that people are free riding, it's often that they don't even realize it. Software engineers can easily forget just how much craftsmanship has gone into the open source code that powers the most basic of applications... "If you work at a for-profit company, take the lead in finding a way to support the code that allows you to do your job so efficiently. The decentralization and volunteer spirit of the open source community needs exactly the same kind of decentralized spirit in every financial contributor. Sustainability is each of our jobs, every day."' -- source: https://news.slashdot.org/story/18/06/23/2113222 Cheers, Peter -- Peter Reutemann Dept. 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 Birth Of PDF
by Lawrence D'Oliveiro 21 Jun '18

<http://www.theregister.co.uk/2018/06/21/how_a_tax_form_kludge_gave_us_25_ye…>: [In 1985] ... both Apple and Adobe wanted to show off the LaserWriter's abilities with some sample files. Warnock thought it would be great to have the printer producing something complex but familiar so he personally hand-programmed an IRS tax form in PostScript. ... all those boxes and form fields required Warnock to code in lots of subroutines and utilities. The page took 2 minutes 45 seconds to print. Jobs was horrified at how slow that was. ... His new version of the IRS tax form printed on the LaserWriter in 22 seconds. In other words, by abandoning all the programming-language constructs (subroutines, conditionals, looping etc) in PostScript and just writing out a straight sequence of imaging commands, the code ran a lot faster, even if it was bigger. The article mentions the release of PDF 2.0, which is now being managed by ISO. Unfortunately, unlike Adobe, ISO do not make their specs available for free.

OpenBSD Disables Intel CPU Hyper-Threading Due To Security Concerns
by Peter Reutemann 21 Jun '18

21 Jun '18

'The OpenBSD project announced today plans to disable support for Intel CPU hyper-threading due to security concerns regarding the theoretical threat of more "Spectre-class bugs." Bleeping Computer reports: Hyper-threading (HT) is Intel's proprietary implementation of Simultaneous Multithreading (SMT), a technology that allows processors to run parallel operations on different cores of the same multi-core CPU. The feature has been added to all Intel CPUs released since 2002 and has come enabled by default, with Intel citing its performance boost as the main reason for its inclusion. But today, Mark Kettenis of the OpenBSD project, said the OpenBSD team was removing support for Intel HT because, by design, this technology just opens the door for more timing attacks. Timing attacks are a class of cryptographic attacks through which a third-party observer can deduce the content of encrypted data by recording and analyzing the time taken to execute cryptographic algorithms. The OpenBSD team is now stepping in to provide a new setting to disable HT support because "many modern machines no longer provide the ability to disable hyper-threading in the BIOS setup."

Widely used D-Link modem/router under mass attack by potent IoT botnet
by Peter Reutemann 21 Jun '18

'Malicious hackers are mass exploiting a critical vulnerability in D-Link DSL routers in an attempt to make them part of Satori, the potent Internet-of-things botnet that is used to take down websites and mine digital coins, researchers said. Since making its debut late last year, Satori has proven to be a particularly versatile and sophisticated botnet. It made a name for itself in December when it infected more than 100,000 Internet-connected devices in just 12 hours by exploiting remote code-execution vulnerabilities in Huawei and RealTek routers. A month later, Satori operators released a new version that infected devices used to mine digital coins, proving that the IoT botnet could also take control of more traditional computing devices. In February, Satori resurfaced when it infected tens of thousands of routers manufactured by Dasan Networks.' -- source: https://arstechnica.com/information-technology/2018/06/widely-used-d-link-m… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

TPP Versus Free-Software Licensing
by Lawrence D'Oliveiro 20 Jun '18

20 Jun '18

Seems like the “CPTPP” aka “TPP-11” (TPP minus the USA) may not be entirely free of objectionable provisions. A submission to the Australian ratification process <https://www.techdirt.com/articles/20180615/09090440050/open-source-industry…> has pointed out the following problematic clause: No Party shall require the transfer of, or access to, source code of software owned by a person of another Party, as a condition for the import, distribution, sale or use of such software, or of products containing such software, in its territory. As you may know, such an access requirement is an integral part of copyleft licences like the GPL. What this clause seems to be saying is that such a requirement is unenforceable under the TPP.

macOS Breaks Your OpSec by Caching Data From Encrypted Hard Drives
by Peter Reutemann 18 Jun '18

18 Jun '18

'Apple's macOS surreptitiously creates and caches thumbnails for images and other file types stored on password-protected / encrypted containers (hard drives, partitions), according to macOS security experts Wojciech Regula and Patrick Wardle. From a report: The problem is that these cached thumbnails are stored on non-encrypted hard drives, in a known location and can be easily retrieved by malware or forensics tools, revealing some of the content stored on encrypted containers. On macOS, these thumbnails are created by Finder and QuickLook. Finder is the default macOS file explorer app, similar to Windows Explorer. Whenever a user navigates to a new folder, Finder automatically loads icons for the files located in those folders. For images, these icons are gradually replaced by thumbnails that show a preview of the image at a small scale.' -- source: https://apple.slashdot.org/story/18/06/18/1336248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Another Reason To Move To GPLv3?
by Lawrence D'Oliveiro 18 Jun '18

18 Jun '18

Red Hat has decided <http://www.theregister.co.uk/2018/06/18/red_hat_gpl_violation/> that it prefers the more lenient remediation provisions in GPLv3 for licence violators. So as a matter of policy, it is going to adhere to them even for products it has licensed GPL/LGPLv2.x. [Licensing export Paul] Berg said the GPL and LGPL version 3 have more lenient termination clauses for good reason: Most people have no idea they've violated the terms and would comply if made aware of the problem. The article mentions the case of a Linux kernel developer who has been exploiting--some say abusing--his contributions to extract money from various firms. This has been a great annoyance to the kernel community--the same community that made it clear some years ago that they were against moving to GPLv3.

Another Day, Another Intel CPU Security Hole: Lazy State
by Peter Reutemann 15 Jun '18

15 Jun '18

'The latest Intel revelation, Lazy FP state restore, can theoretically pull data from your programs, including encryption software, from your computer regardless of your operating system. Like its forebears, this is a speculative execution vulnerability. In an interview, Red Hat Computer Architect Jon Masters explained: "It affects Intel designs similar to variant 3-a of the previous stuff, but it's NOT Meltdown." Still, "it allows the floating point registers to be leaked from another process, but alas that means the same registers as used for crypto, etc." Lazy State does not affect AMD processors. This vulnerability exists because modern CPUs include many registers (internal memory) that represent the state of each running application. Saving and restoring this state when switching from one application to another takes time. As a performance optimization, this may be done "lazily" (i.e., when needed) and that is where the problem hides. This vulnerability exploits "lazy state restore" by allowing an attacker to obtain information about the activity of other applications, including encryption operations' -- source: https://it.slashdot.org/story/18/06/14/1553255 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Decades-old PGP bug allowed hackers to spoof just about anyone’s signature
by Peter Reutemann 15 Jun '18

15 Jun '18

'For their entire existence, some of the world's most widely used email encryption tools have been vulnerable to hacks that allowed attackers to spoof the digital signature of just about any person with a public key, a researcher said Wednesday. GnuPG, Enigmail, GPGTools, and python-gnupg have all been updated to patch the critical vulnerability. Enigmail and the Simple Password Store have also received patches for two related spoofing bugs. Digital signatures are used to prove the source of an encrypted message, data backup, or software update. Typically, the source must use a private encryption key to cause an application to show that a message or file is signed. But a series of vulnerabilities dubbed SigSpoof makes it possible in certain cases for attackers to fake signatures with nothing more than someone’s public key or key ID, both of which are often published online. The spoofed email shown at the top of this post can't be detected as malicious without doing forensic analysis that's beyond the ability of many users.' -- source: https://arstechnica.com/information-technology/2018/06/decades-old-pgp-bug-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Russian Censorship Of Telegram
by Lawrence D'Oliveiro 14 Jun '18

14 Jun '18

Bruce Schneier <https://www.schneier.com/blog/archives/2018/06/russian_censors.html>: Iran attempts to block Telegram have been more successful than Russia's, less because Iran's censorship technology is more sophisticated but because Telegram is not willing to go as far to defend Iranian users. The reasons are not rooted in business decisions. Simply put, Telegram is a Russian product and the designers are more motivated to poke Russia in the eye. ... In 1993, John Gilmore famously said that "The Internet interprets censorship as damage and routes around it." That was technically true when he said it but only because the routing structure of the Internet was so distributed. As centralization increases, the Internet loses that robustness, and censorship by governments and companies becomes easier.

KDE Slimbook 2 Review

'The kind folks at Slimbook recently sent me the latest generation of their ultrabook-style laptop line for review, the KDE Slimbook 2. You can hear my thoughts on the latest episode of the Ubuntu Podcast, released on June 7th 2018. Slimbook are a small laptop vendor based in Spain. All the laptops ship with KDE Neon as the default operating system. In addition to their hardware, they also contribute to and facilitate local Free Software events in their area. I was sent the laptop only for review purposes. There's no other incentive provided, and Slimbook didn't see this blog post before I published it. Being a small vendor, they don't have the same buying power with OEM vendors as other big name laptop suppliers. This is reflected in the price you pay. You're supporting a company who are themselves supporting Free Software developers and communities. If you're after the cheapest possible laptop, and don't care about its origin or the people behind the device, then maybe this laptop isn't for you. However, if you like to vote with your wallet, then the KDE Slimbook should absolutely be on your list to seriously consider.' -- source: https://popey.com/blog/posts/kde-slimbook-2-review.html Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How Much Physical Memory Do I Have?
by Lawrence D'Oliveiro 07 Jun '18

07 Jun '18

The free(1) <https://linux.die.net/man/1/free> command shows you system memory usage. E.g. on my laptop a few seconds ago: ldo(a)theodora:~> free total used free shared buff/cache available Mem: 7922644 1210968 3137520 135964 3574156 6265612 Swap: 8388604 24912 8363692 But there’s something not quite right about that “total” number. The machine has 8GiB of RAM, which should show as 8388608KiB. What happened to the remaining 465964KiB? That is taken up by the kernel. But where can you find a figure for this amount? Where can you make up a total that adds up to 8388608KiB? Seems there is no such place, at least not one accessible to non-privileged software. free(1) gets its info from /proc/meminfo, which is where the kernel reports it. But there is no place in this file (or anywhere else that I know of) that the kernel calculates its own memory usage. However, there is a privileged tool, dmidecode(8) <https://linux.die.net/man/8/dmidecode>, which can get information direct from the “DMI” (aka “SMBIOS”) table. In particular, the command dmidecode -t 17 on the laptop reports two “Memory Device” entries (slots for RAM DIMMs?), one of which says “Size: No Module Installed” while the other has “Size: 8192 MB” (which obviously means 8192MiB). So you have to take the total from here as your actual physical RAM, and subtract the amount shown by free(1) (or read from /proc/meminfo) to get the kernel RAM usage.

Microsoft Addresses Pressure From Developer Community, Promises To Rename GVFS
by Peter Reutemann 07 Jun '18

07 Jun '18

'Earlier this week an article ran about how Microsoft's multi-year refusal to rename its terabyte-scale Git extension "GVFS" (Git Virtual File System) had drawn the ire and dismay of the GNOME GVfs project (Gnome Virtual File System) which predates the Microsoft project by years. Thanks to Slashdot coverage and community pressure, Microsoft has now officially promised to rename GVFS to something else, and is asking the community for suggestions for a new name. Is this an official sign that MIcrosoft is finally listening to developers (albeit with a Slashdot-level of negative attention), or are they simply trying to appease the crowd while they are still in the news due to their acquisition of GitHub?' -- source: https://developers.slashdot.org/story/18/06/06/132215 Cheers, Peter -- Peter Reutemann Dept. 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 Adds Post-Quantum Cryptography To an OpenVPN Fork
by Peter Reutemann 07 Jun '18

07 Jun '18

'Microsoft recently published an interesting open source project called "PQCrypto-VPN" that implements post-quantum cryptography (PQC) within OpenVPN. Being developed by the Microsoft Research Security and Cryptography group, as part of their research into post-quantum cryptography, this fork is being used to test PQC algorithms and their performance and functionality when used with VPNs. Microsoft's PQCrypto-VPN is published on Github and allows anyone to build an OpenVPN implementation that can encrypt communications using three different post-quantum cryptography protocols, with more coming as they are developed. These protocols are: (1) Frodo: a key exchange protocol based on the learning with errors problem (2) SIKE: a key exchange protocol based on Supersingular Isogeny Diffie-Hellman and (3) Picnic: a signature algorithm using symmetric-key primitives and non-interactive zero-knowledge proofs.' -- source: https://tech.slashdot.org/story/18/06/06/138258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

UN Plan To Move The World To IPv6
by Lawrence D'Oliveiro 06 Jun '18

06 Jun '18

The UN has a plan to try to increase IPv6 adoption <http://www.theregister.co.uk/2018/05/30/internet_engineers_united_nations_i…>. However, it does it by essentially saddling IPv6 with all the limitations of IPv4 that IPv6 was specifically created to overcome. The UN has been trying for a while to take over governance of the Internet and its standards. This has been fought off by a US-led effort in favour of the IETF, ICANN etc -- all the bodies we know and love. However, the UN can claim some moral high ground in its advocacy for greater adoption among the developing world -- places where such bodies tend to be under-represented.

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/

'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/

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

'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.

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/

Mystery Donor Pledges $1 Million To The GNOME Foundation
by Peter Reutemann 27 May '18

27 May '18

'This week, The GNOME Foundation made a shocking revelation: a mystery donor has pledged $1 million dollars. We don't know who is promising the money -- it could be a rich man or woman, but more likely -- and this is pure speculation -- it is probably a company that benefits from GNOME, such as Red Hat or Canonical. "An anonymous donor has pledged to donate up to $1,000,000 over the next two years, some of which will be matching funds.

Ask Slashdot: Some Good Linux Desktop Option For Kids?
by Peter Reutemann 17 May '18

'I'm looking to re-purpose some of the older hardware that I've held onto to create something of a starter machine for my kids (both aged below 10). At this point it's still just a few shortcut icons I can setup on the desktop for them, primarily to web tools/sites they use, but I'd like some flexibility; everything I've read suggests options that haven't had any activity since 2015.

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.

Fedora-Based Linux Distro Korora Halts Development
by Peter Reutemann 16 May '18

16 May '18

'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

But in that same article, one of the comments linked to this item <http://www.datacenterknowledge.com/design/cloudflare-bets-arm-servers-it-ex…> which says that Cloudflare is going all in on using ARM servers to expand its CDN worldwide. I suppose content delivery is a market segment where sheer CPU grunt is less important than I/O throughput, power efficiency etc.

Chrome 66 Arrives With Autoplaying Content Blocked By Default

'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

'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/

You Can Now Run Linux Apps On Chrome OS

'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/

Microsoft Quarterly Report
by Lawrence D'Oliveiro 27 Apr '18

27 Apr '18

Just some items I found notable from here <https://arstechnica.com/gadgets/2018/04/even-windows-revenue-is-up-in-micro…>: * Office 365 is up, traditional MS Office is down. * Corporate sales of Windows are up, while consumer sales are down (“below the general decline of the PC market”). In each case, the former is growing faster than the latter is declining, so overall business is up.

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?

Drupal Warns of New Remote-Code Bug, the Second in Four Weeks
by Peter Reutemann 26 Apr '18

26 Apr '18

'For the second time in a month, websites that use the Drupal content management system are confronted with a stark choice: install a critical update or risk having your servers infected with ransomware or other nasties. From a report: Maintainers of the open-source CMS built on the PHP programming language released an update patching critical remote-code vulnerability on Wednesday. The bug, formally indexed as CVE-2018-7602, exists within multiple subsystems of Drupal 7.x and 8.x. Drupal maintainers didn't provide details on how the vulnerability can be exploited other than to say attacks work remotely. The maintainers rated the vulnerability "critical" and urged websites to patch it as soon as possible.' -- source: https://developers.slashdot.org/story/18/04/25/1956214 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

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.

Commentary <https://www.schneier.com/blog/archives/2018/04/securing_electi_1.html> from Bruce Schneier: We can securely bank online, but can't securely vote online. If we could do away with anonymity -- if everyone could check that their vote was counted correctly -- then it would be easy to secure the vote. ... 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

'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...

by Peter Reutemann 03 Apr '18

03 Apr '18

'Today, version 28 of the Fedora finally achieves beta status. After a short delay -- it was scheduled to be available a week earlier -- the distro is back on track, and looking better than ever. As is typical now, there are three versions of the operating system -- Atomic Host, Server, and Workstation. While all three have their places, normal desktop computer users will want to focus on Workstation. While there are plenty of new features (and bugs), the most exciting aspect of Fedora 28 Workstation is the inclusion of the GNOME 3.28 desktop environment.' -- source: https://linux.slashdot.org/story/18/04/03/1846233 Cheers, Peter -- Peter Reutemann Dept. 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. "Coming to terms with a dangerous heart condition should never have cost me fundamental control over the technology that my life relies on", said Sandler... "This issue is personal not just for me but for anyone who relies on software, and today that means every single person."

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/

Phoronix has now put out Raspberry Pi 3 B+ benchmarks showing that the Ethernet performance is indeed much faster now but still doesn't stack up to other high performance boards, the SoC temperature is noticeably lower than the very warm Raspberry Pi 3, and the overall performance is a nice upgrade while retaining the same price point as its predecessors. Follow up tests looking at the Wi-Fi performance also show the new 802.11ac dual-band wireless to be much faster as well.' -- source: https://hardware.slashdot.org/story/18/03/25/0556258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hate-Speech 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/

Windows Server 2019 Will Feature Linux and Kubernetes Support
by Peter Reutemann 22 Mar '18

22 Mar '18

'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
by Lawrence D'Oliveiro 21 Mar '18

21 Mar '18

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/
