Microsoft Begins Accepting Extensions For Its Edge Chromium Browser
by Peter Reutemann 18 Dec '19

18 Dec '19

'Microsoft's new Chromium-based Edge browser is now open to developers to submit extensions. The updated version of Edge is set to launch on January 15. From a report: Microsoft says that if a developer has already created an extension for Google Chrome, there shouldn't be any additional work to port it over to Edge Chromium. The browser will be the new default delivered to all 900 million Windows 10 users, so developers should have no reason not to port their extensions over.' -- source: https://slashdot.org/story/19/12/17/1621248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla To Add Second DNS-over-HTTPS (DoH) Provider in Firefox
by Peter Reutemann 18 Dec '19

18 Dec '19

'Mozilla has announced that NextDNS would be joining Cloudflare as the second DNS-over-HTTPS (DoH) provider inside Firefox. From a report: The browser maker says NextDNS passed the conditions imposed by its Trusted Recursive Resolver (TRR) program, and can now be added as a second option for DoH inside Firefox. These conditions include (1) limiting the data NextDNS collects from the DoH server used by Firefox users; (2) being transparent about the data they collect; and (3) promising not to censor, filter, or block DNS traffic unless specifically requested by law enforcement. DNS-over-HTTPS, or DoH, is a new feature that was added to Firefox last year. When enabled, it encrypts DNS traffic coming in and out of the browser. DNS traffic is not only encrypted but also moved from port 53 (for DNS traffic) to port 443 (for HTTPS traffic), effectively hiding DNS queries and replies inside the browser's normal stream of HTTPS content. This encrypted DNS traffic reaches a so-called DoH resolver. Here, the DoH traffic is decrypted and the DoH resolver makes the DNS query on the user's behalf, receives the result, encrypts it, and sends it back to the user's browser -- also disguised inside encrypted HTTPS content.' -- source: https://tech.slashdot.org/story/19/12/17/1922254 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/

Npm Team Warns of New 'Binary Planting' Bug
by Peter Reutemann 17 Dec '19

17 Dec '19

' The team behind npm, the biggest package manager for JavaScript libraries, issued a security alert yesterday, advising all users to update to the latest version (6.13.4) to prevent "binary planting" attacks. From a report: Npm (Node.js Package Manager) devs say the npm command-line interface (CLI) client is impacted by a security bug -- a combination between a file traversal and an arbitrary file (over)write issue. The bug can be exploited by attackers to plant malicious binaries or overwrite files on a user's computer. The vulnerability can be exploited only during the installation of a boobytrapped npm package via the npm CLI. "However, as we have seen in the past, this is not an insurmountable barrier," said the npm team, referring to past incidents where attackers planed backdoored or boobytrapped packages on the official npm repository. Npm devs say they've been scanning the npm portal for packages that may contain exploit code designed to exploit this bug, but have not seen any suspicious cases. "That does not guarantee that it hasn't been used, but it does mean that it isn't currently being used in published packages on the [official npm] registry," npm devs said.' -- source: https://it.slashdot.org/story/19/12/16/1513245 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 Halts Chrome 79 Rollout After It Breaks Some Android Apps
by Peter Reutemann 16 Dec '19

16 Dec '19

'Chrome 79 is creating an issue with WebView (the Android component that allows apps to display content from the web), reports 9to5Google: On Friday morning, Android developers reliant on WebView and local storage began encountering an issue where their apps lost data after users updated to version 79 of WebView. Those affected took to Chromium's bug tracker, and have described the incident as a "catastrophe" and "major issue." To end users, it's as if apps were entirely reset and just downloaded for the first time. This includes saved data disappearing or being logged out. Given the level of system opacity, most will blame developers for a problem that's out of their hands. By that afternoon, Google engineers responded and isolated the issue to "profile layout changes" where "local storage was missed off the list of files migrated." A member of the Chromium team apologized Saturday morning, with the Chrome/WebView rollout halted after 50% of devices already received the update. At the highest priority level (P0), Google is currently "working on a solution that minimizes the data loss, and that can be rolled out safely." The last guidance for a patch is 5-7 days.' -- source: https://tech.slashdot.org/story/19/12/15/181240 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/

'Link in Bio' is a Slow Knife
by Peter Reutemann 15 Dec '19

15 Dec '19

'Anil Dash: We don't even notice it anymore -- "link in bio." It's a pithy phrase, usually found on Instagram, which directs an audience to be aware that a pertinent web link can be found on that user's profile. Its presence is so subtle, and so pervasive, that we barely even noticed it was an attempt to kill the web. Links on the web are incredibly powerful. There are decades of theory behind the role of hyperlinks in hypertext -- did you know in most early versions, links were originally designed to be two-way? You'd be able to see every page on the web that links to this one. But even in the very simple form that we've ended up with on the World Wide Web for the last 30 years, links are incredibly powerful, opening up valuable connections between unexpected things. For a closed system, those kinds of open connections are deeply dangerous. If anyone on Instagram can just link to any old store on the web, how can Instagram -- meaning Facebook, Instagram's increasingly-overbearing owner -- tightly control commerce on its platform? If Instagram users could post links willy-nilly, they might even be able to connect directly to their users, getting their email addresses or finding other ways to communicate with them. Links represent a threat to closed systems. Here's the thing, though: people like links. So closed systems have to present a pressure release valve. Hashtags are a great way out. They use the semiotics of links (early versions of hashtags on social platforms were really barely more than automated links to a search for a particular term) but are also constrained by the platforms they live on. A hashtag is easier to gather into a database, to harvest, to monetize. It's much easier, sure, but it also doesn't have all the messiness of a real link. Instagram doesn't have to worry that clicking on its hashtags will accidentally lead people to Twitter, or vice versa.' -- source: https://tech.slashdot.org/story/19/12/12/1540216 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/

Building Your Own Open Source, Privacy-Protecting Voice Assistant With A Raspberry Pi
by Peter Reutemann 15 Dec '19

15 Dec '19

'PC Magazine's "tech nerd" Whitson Gordon writes that "Once you start using a smart speaker to set reminders, play the news, or turn the lights on, it's hard to go back." But if you want the convenience of voice control without the data-collecting tech giant behind the scenes, an open-source project called Mycroft is a great alternative. And you can run it right on a Raspberry Pi. Mycroft is a free, open-source voice assistant designed to run on Linux-based devices... Mycroft has been around for quite a few years, but it's recently gained a bit more notoriety thanks to privacy concerns surrounding data collection at Amazon and Google. Unlike those assistants, Mycroft only collects data if you opt in during setup. And for the users who do opt in, Mycroft promises never to sell your data to advertisers or third parties -- instead, it only uses it to help developers improve the product. Mycroft even uses the privacy-focused DuckDuckGo as its search engine instead of Google when you ask for information. Mycroft makes its own smart speaker called the Mark I, though it's currently sold out with a new Mark II (video here) on the way. However, since the project is open-source, you can install Mycroft on just about any Linux machine, including the Raspberry Pi (thanks to a pre-made build called Picroft). Using Mycroft on the Pi is free, but you can also subscribe to a $1.99-per-month plan to help support its development -- you'll even get a few goodies, like other voices that sound more lifelike than the default robotic voice.' -- source: https://hardware.slashdot.org/story/19/12/14/1954242 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/

Managing Spectre/Meltdown-Style Vulnerabilities At AWS
by Lawrence D'Oliveiro 15 Dec '19

15 Dec '19

Some insights <https://www.theregister.co.uk/2019/12/10/linux_kernel_aws/> into the different priorities often faced by different groups faced with the same problem. Linux kernel developer Greg Kroah-Hartman says to avoid most of these “MDS” (“Microarchitectural Data Sampling”) vulnerabilities, you must turn off Intel’s hyperthreading, full stop. Amazon, on the other hand, find that the resulting 30-40% performance loss is unacceptable for many of their customers. So they have come up with a tweaked scheduler algorithm for their Linux kernels that avoids running two different guests on the same physical core at the same time. With this and other careful management, they claim to be able to keep their customers safe from each other, with much less dramatic performance impact. But then you have the downside that the mainline kernel is not interested in accepting patches with such narrow applicability. Of course Amazon would like to come up with something they will accept, just to reduce their own maintenance burden.

Mozilla To Force All Add-on Devs To Use 2FA To Prevent Supply-Chain Attacks
by Peter Reutemann 14 Dec '19

14 Dec '19

'Mozilla announced this week that all developers of Firefox add-ons must enable a two-factor authentication (2FA) solution for their account. From a report: "Starting in early 2020, extension developers will be required to have 2FA enabled on AMO [the Mozilla Add-Ons portal]," said Caitlin Neiman, Add-ons Community Manager at Mozilla. "This is intended to help prevent malicious actors from taking control of legitimate add-ons and their users," Neiman added. When this happens, hackers can use the developers' compromised accounts to ship tainted add-on updates to Firefox users. Since Firefox add-ons have a pretty privileged position inside the browser, an attacker can use a compromised add-on to steal passwords, authentication/session cookies, spy on a user's browsing habits, or redirect users to phishing pages or malware download sites. These types of incidents are usually referred to as supply-chain attacks.' -- source: https://it.slashdot.org/story/19/12/13/152239 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 Police Raid NGINX Moscow Office
by Peter Reutemann 13 Dec '19

13 Dec '19

'Russian police have raided today the Moscow offices of NGINX, Inc., a subsidiary of F5 Networks and the company behind the internet's most popular web server technology. From a report: Equipment was seized and employees were detained for questioning. Moscow police executed the raid after last week the Rambler Group filed a copyright violation against NGINX Inc., claiming full ownership of the NGINX web server code. The Rambler Group is the parent company of rambler.ru, one of Russia's biggest search engines and internet portals. According to copies of the search warrant posted on Twitter today, Rambler claims that Igor Sysoev developed NGINX while he was working as a system administrator for the company, hence they are the rightful owner of the project. Sysoev created NGINX in the early 2000s and open-sourced the NGINX code in 2004. In 2009, he founded NGINX, Inc., a US company, to provide adjacent tools and support services for NGINX deployments. The company is based in San Francisco, but has offices all over the world, including Moscow. The NGINX server's source code is still free and managed through an open-source model, although a large chunk of the project's primary contributors are NGINX, Inc. employees, who have a firm grip on the project's stewardship.' -- source: https://news.slashdot.org/story/19/12/12/175245 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/

Inside the Podcast that Hacks Ring Camera Owners Live on Air
by Peter Reutemann 13 Dec '19

13 Dec '19

'In the NulledCast podcast hackers livestream the harassment of Ring camera owners after accessing their devices. Hundreds of people can listen. From a report: A blaring siren suddenly rips through the Ring camera, startling the Florida family inside their own home. "It's your boy Chance on Nulled," a voice says from the Ring camera, which a hacker has taken over. "How you doing? How you doing?" "Welcome to the NulledCast," the voice says. The NulledCast is a podcast livestreamed to Discord. It's a show in which hackers take over people's Ring and Nest smarthome cameras and use their speakers to talk to and harass their unsuspecting owners. In the example above, Chance blared noises and shouted racist comments at the Florida family. "Sit back and relax to over 45 minutes of entertainment," an advertisement for the podcast posted to a hacking forum called Nulled reads. "Join us as we go on completely random tangents such as; Ring & Nest Trolling, telling shelter owners we killed a kitten, Nulled drama, and more ridiculous topics. Be sure to join our Discord to watch the shows live." Software to hack Ring cameras has recently become popular on the forum. The software churns through previously compromised email addresses and passwords to break into Ring cameras at scale. This has led to a recent spate of hacks that have occurred both during the podcast and at other times, several of which have been covered by local media outlets. In Brookhaven a hacker shouted at a sleeping woman through her hacked Ring camera to wake-up. In Texas, a hacker demanded a couple pay a bitcoin ransom. Hackers targeted a family in DeSoto County, Mississippi, and spoke through the device to one of the young children.' -- source: https://yro.slashdot.org/story/19/12/12/204240 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 SGX coughs up crypto keys when scientists tweak CPU voltage
by Peter Reutemann 11 Dec '19

11 Dec '19

'To counter the growing sophistication of computer attacks, Intel and other chip makers have built digital vaults into CPUs to segregate sensitive computations and secrets from the main engine computers use. Now, scientists have devised an attack that causes the Software Guard Extensions—Intel's implementation of this secure CPU environment to divulge cryptographic keys and induce potentially dangerous memory errors. Plundervault, as the attack has been dubbed, starts with the assumption that an attacker is able to run privileged software on a targeted computer. While that's a lofty prerequisite, it's precisely the scenario Intel's SGX feature is designed to protect against. The chipmaker bills SGX as a private region that uses hardware-based memory encryption to isolate sensitive computations and data from malicious processes that run with high privilege levels. Intel goes as far as saying that "Only Intel SGX offers such a granular level of control and protection." But it turns out that subtle fluctuations in voltage powering the main CPU can corrupt the normal functioning inside the SGX. By subtly increasing or decreasing the current delivered to a CPU—operations known as "overvolting" and "undervolting"—a team of scientists has figured out how to induce SGX faults that leak cryptographic keys, break integrity assurances, and potentially induce memory errors that could be used in other types of attacks.' -- source: https://arstechnica.com/information-technology/2019/12/scientists-pluck-cry… 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/

Are You One Of Avast's 400 Million Users? This Is Why It Collects And Sells Your Web Habits.
by Peter Reutemann 11 Dec '19

11 Dec '19

'Avast, the multibillion-dollar Czech security company, doesn't just make money from protecting its 400 million users' information. It also profits in part because of sales of users' Web browsing habits and has been doing so since at least 2013. From a report: That's led to some labelling its tools "spyware," the very thing Avast is supposed to be protecting users from. Both Mozilla and Opera were concerned enough to remove some Avast tools from their add-on stores earlier this month, though the anti-virus provider says it's working with Mozilla to get its products back online. But recently appointed chief executive Ondrej Vlcek tells Forbes there's no privacy scandal here. All that user information that it sells cannot be traced back to individual users, he asserts. Here's how it works, according to Vlcek: Avast users have their Web activity harvested by the company's browser extensions. But before it lands on Avast servers, the data is stripped of anything that might expose an individual's identity, such as a name in the URL, as when a Facebook user is logged in. All that data is analysed by Jumpshot, a company that's 65%-owned by Avast, before being sold on as "insights" to customers. Those customers might be investors or brand managers. What do those customers get? Vlcek says Jumpshot, which was initially acquired in 2013, provides "insights on how cohorts of users on the internet use the web." For instance, it could show a percentage of visitors who went from one website to another. That could be useful to anyone monitoring an advertising campaign. "Typical customers would be, for example, investors, who would be interested in how online companies are doing in terms of their new campaigns," the new Avast chief explains. Say Amazon launches a new product -- Jumpshot could determine how much interest it's getting online.' -- source: https://it.slashdot.org/story/19/12/10/1922243 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 is a step closer to mainstream adoption
by Peter Reutemann 10 Dec '19

10 Dec '19

'As of this morning, Linux network stack maintainer David Miller has committed the WireGuard VPN project into the Linux "net-next" source tree. Miller maintains both net and net-next—the source trees governing the current implementation of the Linux kernel networking stack and the implementation of the next Linux kernel's networking stack, respectively. This is a major step forward for the WireGuard VPN project. Net-next gets pulled into the new Linux kernel during its two-week merge window, where it becomes net. With WireGuard already a part of net-next, this means that—barring unexpected issues—there should be a Linux kernel 5.6 release candidate with built-in WireGuard in early 2020. Mainline kernel inclusion of WireGuard should lead to significantly higher uptake in projects and organizations requiring virtual private network capability. Normal, day-to-day Linux users probably won't see in-kernel WireGuard until late 2020. Ubuntu is one of the faster-moving mainstream distributions, and its next Long Term Support (LTS) release is in April 2020. But the Linux 5.6 kernel and Ubuntu 20.04 will likely be in release candidate status at the same time, so its inclusion in 20.04 seems unlikely. The interim 20.10 Ubuntu release seems like a much safer bet for Canonical's first use of a 5.6 or later kernel. Red Hat Enterprise Linux (RHEL) inclusion will likely be a year or more beyond that; the current RHEL 8.1 shipped in May 2019 with the 4.18 kernel, which was already 9 months old. Although highly speculative, it's also possible that WireGuard could land in-kernel on Ubuntu 20.04 even without the 5.6 kernel—Donenfeld offered to do the work backporting WireGuard into earlier Ubuntu kernels directly. Donenfeld also stated today that a 1.0 WireGuard release is "on the horizon."' -- source: https://arstechnica.com/gadgets/2019/12/wireguard-vpn-is-a-step-closer-to-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/

Linux Users Can Now Use Disney+ After DRM Fix
by Peter Reutemann 09 Dec '19

09 Dec '19

'"Linux users can now stream shows and movies from the Disney+ streaming service after Disney lowered the level of their DRM requirements," reports Bleeping Computer: When Disney+ was first launched, Linux users who attempted to watch shows and movies were shown an error stating "Something went wrong. Please try again. If the problem persists, visit the Disney+ Help Center (Error Code 83)." As explained by Hans de Goede, this error was being caused by the Disney+ service using the highest level of security for the Widevine Digital Rights Management (DRM) technology. As some Linux and Android devices did not support this higher DRM security level, they were unable to stream Disney+ shows in their browsers... Yesterday, Twitter users discovered that Disney+ had suddenly started working on Linux browsers after the streaming service tweaked their DRM security levels... Even with Disney+ lowering the DRM requirements, users must first make sure DRM is enabled in the browser. For example, Disney+ will not work with Firefox unless you enable the "Play DRM-controlled content" setting in the browser.' -- source: https://linux.slashdot.org/story/19/12/08/169213 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/

by Peter Reutemann 08 Dec '19

08 Dec '19

'At its Snapdragon Summit in Maui, Hawaii this week, Qualcomm unveiled the new Snapdragon 865 Mobile Platform, which enable next year's flagship 5G Android phones with more performance, a stronger Tensor-based AI processor and a very interesting new forthcoming feature not yet offered for any smartphone platform to date. The company announced that it will eventually start delivering driver updates for its Adreno GPU engines on board the Snapdragon 865 as downloadable packages via the Google Play Store. This is big news for smartphones, as GPU drivers are rarely updated out of band, if ever, and typically have to wait for the next major Android release. And even then, many OEMs don't bother putting in the effort to ensure that mobile GPUs are running the most current graphics drivers from Qualcomm. The process, which would have to be pre-qualified by major OEMs as well, will be akin to what the PC GPU 3D graphics driver ecosystem has been benefiting from for a long time, for maximum performance and compatibility. Unfortunately, at least currently, GPU driver update support is limited to only the Adreno 650 core on board the new Snapdragon 865, which currently supports updating drivers in this fashion. Here's hoping this program is met with success and Qualcomm will begin to enable the feature for legacy and new midrange Snapdragon platforms as well.' -- source: https://tech.slashdot.org/story/19/12/06/2132212 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/

Keybase Moves To Stop Onslaught of Spammers on Encrypted Message Platform
by Peter Reutemann 07 Dec '19

07 Dec '19

'Keybase started off as co-founder and developer Max Krohn's "hobby project" -- a way for people to share PGP keys with a simple username-based lookup. Then Chris Coyne (who also was cofounder of OkCupid and SparkNotes) got involved and along came $10.8 million in funding from a group of investors led by Andreesen Horowitz. And then things got increasingly more complicated. Keybase aims to make public-key encryption accessible to everyone, for everything from messaging to file sharing to throwing a few crypto-coins someone's way. But because of that level of accessibility, Keybase faces a very OkCupid kind of problem: after drawing in people interested in easy public-key crypto-based communications and then drawing in blockchain lovers with its partnership with (and funding from) Stellar.org, Keybase has also drawn in spammers and scammers. And that has brought a host of alerts and messages that have made what was once a fairly clear communications channel into one clogged with unwanted alerts, messages, and other unpleasantry -- raising a chorus of complaints in Keybase's open chat channel. It turns out there's a reason spell check keeps wanting to tell me that Keybase should be spelled "debase." Keybase's leadership is promising to do something to fix the spam problem -- or at least make it easier to report and block abusers. In a blog post, Krohn and Coynes wrote, "To be clear, the current spam volume isn't dire, YET. Keybase still works great. But we should act quickly." But the measures promised by Keybase won't completely eliminate the issue. And Keybase execs have no interest in getting involved with additional steps that they see as censorship. "Keybase is a private company and we do retain our rights to kick people out," the co-founders said in the blog post. "That hammer will not be used because someone is mostly disliked, as long as they're playing nicely on Keybase."' -- source: https://it.slashdot.org/story/19/12/06/1610259 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 Linux Vulnerability Lets Attackers Hijack VPN Connections
by Peter Reutemann 06 Dec '19

06 Dec '19

'Security researchers found a new vulnerability allowing potential attackers to hijack VPN connections on affected *NIX devices and inject arbitrary data payloads into IPv4 and IPv6 TCP streams. They disclosed the security flaw tracked as CVE-2019-14899 to distros and the Linux kernel security team, as well as to others impacted such as Systemd, Google, Apple, OpenVPN, and WireGuard. The vulnerability is known to impact most Linux distributions and Unix-like operating systems including FreeBSD, OpenBSD, macOS, iOS, and Android. A currently incomplete list of vulnerable operating systems and the init systems they came with is available below, with more to be added once they are tested and found to be affected: Ubuntu 19.10 (systemd), Fedora (systemd), Debian 10.2 (systemd), Arch 2019.05 (systemd), Manjaro 18.1.1 (systemd), Devuan (sysV init), MX Linux 19 (Mepis+antiX), Void Linux (runit), Slackware 14.2 (rc.d), Deepin (rc.d), FreeBSD (rc.d), and OpenBSD (rc.d). This security flaw "allows a network adjacent attacker to determine if another user is connected to a VPN, the virtual IP address they have been assigned by the VPN server, and whether or not there is an active connection to a given website," according to William J. Tolley, Beau Kujath, and Jedidiah R. Crandall, Breakpointing Bad researchers at University of New Mexico. "Additionally, we are able to determine the exact seq and ack numbers by counting encrypted packets and/or examining their size. This allows us to inject data into the TCP stream and hijack connections," the researchers said.' -- source: https://linux.slashdot.org/story/19/12/05/2022205 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/

Brother of Drug Lord Pablo Escobar Launches 'Unbreakable' Foldable Smartphone
by Peter Reutemann 05 Dec '19

05 Dec '19

'Roberto Escobar, brother of the late drug lord Pablo Escobar, has announced a foldable smartphone that is "very difficult to break" thanks to the screen's "special type of plastic." The Escobar Fold 1, as it is called, significantly undercuts Samsung's Galaxy Fold and Huawei Mate X with a price of only $349. Neowin reports: While all the foldable phones announced so far have a price tag of at least $1,500+, the Escobar Fold 1 will be available from only $349 which includes free shipping and a case as well. It will be sold unlocked and work on all compatible networks worldwide. This makes it cheaper than other non-foldable flagship smartphones available in the market right now. The drug lord's brother has been able to price the phone so low by cutting out the middlemen like networks and retailers. He is also preparing to file a $30 billion class-action lawsuit against Apple for scamming people and wants the company to "give some of their illegal profits back to the people." Like the Huawei Mate X, the Escobar Fold can be unfolded to turn it into a tablet with a screen size of 7.8-inches. The expanded AMOLED display has a 4:3 aspect ratio and an FHD+ resolution. The design language is different from the Samsung Galaxy Fold which features two separate displays, one of which folds.

The Rise and Fall of the PlayStation Supercomputers
by Peter Reutemann 04 Dec '19

04 Dec '19

'"On the 25th anniversary of the original Sony PlayStation, The Verge shares the story of the PlayStation supercomputers," writes Slashdot reader jimminy_cricket. From the report: Dozens of PlayStation 3s sit in a refrigerated shipping container on the University of Massachusetts Dartmouth's campus, sucking up energy and investigating astrophysics. It's a popular stop for tours trying to sell the school to prospective first-year students and their parents, and it's one of the few living legacies of a weird science chapter in PlayStation's history. Those squat boxes, hulking on entertainment systems or dust-covered in the back of a closet, were once coveted by researchers who used the consoles to build supercomputers. With the racks of machines, the scientists were suddenly capable of contemplating the physics of black holes, processing drone footage, or winning cryptography contests. It only lasted a few years before tech moved on, becoming smaller and more efficient. But for that short moment, some of the most powerful computers in the world could be hacked together with code, wire, and gaming consoles. "The game consoles entered the supercomputing scene in 2002 when Sony released a kit called Linux for the PlayStation 2," reports The Verge. Craig Steffen, senior research scientist at the National Center for Supercomputing Applications, and his group hooked up between 60 and 70 PlayStation 2s, wrote some code, and built out a library. "The PS3 entered the scene in late 2006 with powerful hardware and an easier way to load Linux onto the devices," the report adds. "Researchers would still need to link the systems together, but suddenly, it was possible for them to imagine linking together all of those devices into something that was a game-changer instead of just a proof-of-concept prototype."' -- source: https://hardware.slashdot.org/story/19/12/03/2214249 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/

elementary OS 5.1 'Hera' Linux Distro is Here
by Peter Reutemann 04 Dec '19

04 Dec '19

'elementary OS has long been viewed by many as the future of Linux on the PC thanks to its beautiful desktop environment and overall polished experience. Development of the Ubuntu-based operating system has been frustratingly slow, however. This shouldn't be surprising, really, as the team of developers is rather small, and its resources are likely much less than those of larger distributions such as the IBM-backed Fedora or Canonical's Ubuntu. And that is what makes elementary OS so remarkable -- its developers can make magic on a smaller budget. Today, the latest version of the operating system is released. Code-named "Hera," elementary OS 5.1 is now available for download. Support for Flatpak is now baked in -- this is significant, as the developers explain it is "the first non-deb packaging format we've supported out of the box." The Linux kernel now sits at a very modern 5.0. One of the most important aspects of elementary OS, the AppCenter, is now an insane 10 times faster than its predecessor.' -- source: https://tech.slashdot.org/story/19/12/03/1538207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Removes Avast and AVG Extensions From Add-on Portal Over Snooping Claims
by Peter Reutemann 04 Dec '19

04 Dec '19

'Mozilla today removed four Firefox extensions made by Avast and its subsidiary AVG after receiving credible reports that the extensions were harvesting user data and browsing histories. From a report: The four extensions are Avast Online Security, AVG Online Security, Avast SafePrice, and AVG SafePrice. The first two are extensions that show warnings when navigating to known malicious or suspicious sites, while the last two are extensions for online shoppers, showing price comparisons, deals, and available coupons. Mozilla removed the four extensions from its add-ons portal after receiving a report from Wladimir Palant, the creator of the AdBlock Plus ad-blocking extension. Palant analyzed the Avast Online Security and AVG Online Security extensions in late October and found that the two were collecting much more data than they needed to work -- including detailed user browsing history, a practice prohibited by both Mozilla and Google.' -- source: https://yro.slashdot.org/story/19/12/03/1559248 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/

Vulnerability In Fully Patched Android Phones Under Active Attack By Bank Thieves
by Peter Reutemann 03 Dec '19

03 Dec '19

'A vulnerability in millions of fully patched Android phones is being actively exploited by malware that's designed to drain the bank accounts of infected users, researchers said on Monday. The vulnerability allows malicious apps to masquerade as legitimate apps that targets have already installed and come to trust, researchers from security firm Promon reported in a post. Running under the guise of trusted apps already installed, the malicious apps can then request permissions to carry out sensitive tasks, such as recording audio or video, taking photos, reading text messages or phishing login credentials. Targets who click yes to the request are then compromised. Researchers with Lookout, a mobile security provider and a Promon partner, reported last week that they found 36 apps exploiting the spoofing vulnerability. The malicious apps included variants of the BankBot banking trojan. BankBot has been active since 2017, and apps from the malware family have been caught repeatedly infiltrating the Google Play Market. The vulnerability is most serious in versions 6 through 10, which account for about 80% of Android phones worldwide. Attacks against those versions allow malicious apps to ask for permissions while posing as legitimate apps. There's no limit to the permissions these malicious apps can seek. Access to text messages, photos, the microphone, camera, and GPS are some of the permissions that are possible. A user's only defense is to click "no" to the requests. "The vulnerability is found in a function known as TaskAffinity, a multitasking feature that allows apps to assume the identity of other apps or tasks running in the multitasking environment," reports Ars Technica. While Google has removed the [unnamed] malicious apps from its Play Store, according to Promon, the vulnerability is still unfixed in all versions of Android. "Promon is calling the vulnerability 'StrandHogg,' an old Norse term for the Viking tactic of raiding coastal areas to plunder and hold people for ransom," the report adds. "Promon researchers said they identified StrandHogg after learning from an unnamed Eastern European security company for financial institutions that several banks in the Czech Republic reported money disappearing from customer accounts."' -- source: https://it.slashdot.org/story/19/12/02/230254 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/

Huawei Is Now Making Smartphones Without American Chips
by Peter Reutemann 03 Dec '19

03 Dec '19

'"American tech companies are getting the go-ahead to resume business with Chinese smartphone giant Huawei Technologies Co., but it may be too late," reports the Wall Street Journal. Huawei is just building its smartphones without U.S. chips. Huawei's latest phone, which it unveiled in September -- the Mate 30 with a curved display, telephone and wide-angle cameras that competes with Apple Inc.'s iPhone 11 -- contained no U.S. parts, according to an analysis by UBS and Fomalhaut Techno Solutions, a Japanese technology lab that took the device apart to inspect its insides... While Huawei hasn't stopped using American chips entirely, it has reduced its reliance on U.S. suppliers or eliminated U.S. chips in phones launched since May, including the company's Y9 Prime and Mate smartphones, according to Fomalhaut's teardown analysis. Similar inspections by iFixit and Tech Insights Inc., two other firms that take apart phones to inspect components, have come to similar conclusions.' -- source: https://mobile.slashdot.org/story/19/12/02/0146208 Looks like actual competition now...

Rust-Based Redox OS Is Nearly Self-Hosting After Four Years
by Peter Reutemann 02 Dec '19

02 Dec '19

'Redox OS, written in Rust and currently under development, is only "a few months of work away" from self-hosting, meaning that the Rustc compiler would run on Redox itself, according to its creator Jeremy Soller... Redox has a POSIX-compliant C library written in Rust, called relibc. It is Linux-compatible both at the syscall API level and at the syscall ABI (Application binary interface) level, subject to the same architecture. The article notes that the OS's latest release was version 0.5 last March, arguing that it's "best described as experimental..." "Still, if Rust continues to grow in popularity, its characteristics of safety and unimpeded performance seem ideal for creating a new operating system, so perhaps Redox will become more prominent."' -- source: https://linux.slashdot.org/story/19/11/30/2011231 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/

Kali Linux Adds 'Undercover' Mode to Impersonate Windows 10
by Peter Reutemann 02 Dec '19

02 Dec '19

'"Kali Linux 2019.4 was released last week and with it comes an 'Undercover' mode that can be used to quickly make the Kali desktop look like Windows 10," reports Bleeping Computer: Kali is a Linux distribution created for ethical hacking and penetration testing and is commonly used by researchers and red teamers to perform security tests against an organization. As most people are used to seeing Windows and macOS devices being used, it may look suspicious to see a user running Kali Linux with it's distinctive dragon logo and a Linux environment in an office lobby or other public setting. With this in mind, in Kali Linux 2019.4 the developers created a new 'Undercover' mode that will make the desktop look similar to Windows 10 in order to draw less suspicion. The script even hides Kali's dragon logo, explains a post on the Kali blog, so "you can work a bit more incognito. After you are done and in a more private place, run the script again and you switch back to your Kali theme. Like magic...!" "Thanks to Robert, who leads our penetration testing team, for suggesting a Kali theme that looks like Windows to the casual view..."' -- source: https://linux.slashdot.org/story/19/12/01/1825215 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 19.10: It’s fast, like “make old hardware feel new” fast
by Peter Reutemann 28 Nov '19

28 Nov '19

'Leaves are turning. Temperatures have dipped. These are sure signs—if you live in the Northern Hemisphere, at least—that Canonical's Autumn release is upon us. Things are a bit different in 2019, however. Not only is Ubuntu 19.10 nicknamed Eoan Ermine (no, I don't know how you pronounce it either), but it's the best non-LTS Ubuntu release Canonical has ever put out. I should qualify that statement somewhat, because really, as the newest version, it had damn well better be the best Ubuntu ever. But there's more than recency bias behind the sentiment. I've been reviewing Ubuntu for 10 years now, and I was using and interacting with this distro in some form or another for another three or four years before that. After spending recent weeks with Ubuntu 19.10, I can say confidently it is quite simply the best Ubuntu Canonical has ever released. The first reason I like 19.10 so much is that it feels insanely fast. Everyday tasks like opening applications, dragging windows, activating the search interface, and even just moving the cursor around are all noticeably faster than in 19.04. The speed boost is immediately noticeable from the minute you pop in the live CD, and it's even faster once you have 19.10 installed. I happened to be testing a top-of-the-line MacBook around the time I first installed the 19.10 beta on my aging Lenovo x240, and it instantly made the Mac feel like a sloth. Ubuntu 19.10 ran circles around the Mac even on much, much less powerful hardware, and nothing says success during testing like software that makes old hardware feel newer. Even if that were all you got out of Ubuntu 19.10, I'd call it a win.' -- source: https://arstechnica.com/gadgets/2019/11/ubuntu-19-10-quite-simply-the-best-… 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/

tagging arbitrary files (not just mp3s) under Linux

Hi everyone After last night's AGM, I had a conversation with Rod regarding any Linux applications that allow tagging of arbitrary files (not just mp3s) to improve organizing them, similar to what Gmail introduced all those years ago. In the following reddit discussion: https://www.reddit.com/r/linux/comments/3mjwn5/do_any_popular_linux_file_sy… I came across the "TagSpaces" application (open source, AGPL), which seems to fit that bill: https://www.tagspaces.org/ 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/

Just came across this video <https://www.youtube.com/watch?v=VJC6OpGpq0Y>, latest in a series on cooling solutions for a Raspberry π 4. This instalment looks at a couple of purely passive, fanless products that use the case as a heat sink (or vice versa). But on top of that, a recent firmware update from Broadcom has made a massive difference to the running temperature in all the configurations. Summary: passive cooling worked quite well before the update, and now works even better.

The Librem 5 has been “shipping” for a month—but not to backers
by Peter Reutemann 26 Nov '19

26 Nov '19

'Purism announced that shipping of its Librem 5 open source smartphone began in late September. Two months later, nobody outside the company has a Librem 5, and people are getting restless. The Librem 5 is a crowdfunded project—and an ambitious one—so it wasn't much surprise or cause for concern when it missed its original January 2019 delivery target—or the April 2019 target set after January slipped. Both date changes were announced well ahead of time, and the company continued to post progress reports, commit code upstream, and assure backers of its commitment to transparency. (Full disclosure: I am a Librem 5 backer myself and am scheduled to receive a phone in the Evergreen batch.) The new delays are more troubling. On September 5, CEO Todd Weaver announced that the Librem 5 would ship in six iterative batches, codenamed Aspen, Birch, Chestnut, Dogwood, Evergreen, and Fir. The first three batches would effectively be usable prototypes of decreasing roughness; Evergreen would be the first entirely finished hardware production run, and Fir would be a relatively unspecified next-generation design.' -- source: https://arstechnica.com/gadgets/2019/11/the-librem-5-has-been-shipping-for-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla's Annual Buyer's Guide Rates Amazon and Google Security Cameras 'Very Creepy'
by Peter Reutemann 26 Nov '19

26 Nov '19

'"Be Smart. Shop Safe," warns Mozilla's annual buyer's guide for secure connected products. Based on their conversations with developers and dozens of privacy experts, they've awarded smiley faces with different expressions to rate products from "Not Creepy" up to "Super Creepy". "While the variety of smart devices on offer is rapidly increasing, so are the number of products that pay no heed to even basic security measures..." notes the editor of Mozilla's Internet Health Report. "Now that more and more companies collect personal data about you, including audio and video of your family, and sensitive biometric and health information, like your heart rate and sleeping habits, it's worrying that more are not upfront about the privacy and security of their products." Or, as The Next Web writes, "god bless Mozilla for having our lazy backs." And, well, if you're a user of any Ring camerasâ¦ we're sorry. Basically, there are five things that every product must do: - Have automatic security updates, so they're protected against the newest threats - Use encryption, meaning bad actors can't just snoop on your data - Include a vulnerability management pathway, which makes reporting bugs easy and, well, possible - Require users to change the default password (if applicable), because that makes devices far harder to access - Privacy policies -- ones that relate to the product specifically, and aren't just generic Doesn't seem too much to ask right...? Well, of the 76 devices Mozilla selected, 60 of them passed this test... And what devices didn't meet the criteria? There were nine of them overall (including the Artie 3000 Coding Robot and the Wemo Wifi Smart Dimmer), but the real loser in this test is the Amazon-owned Ring. Three of the company's products (which is effectively all of their major devices) didn't meet Mozilla's criteria. Yes, that's right, the Ring Video Doorbell, Ring Indoor Cam, and Ring Security Cam all didn't meet minimum standards for security.... The main reasons for not meeting this criteria is due Ring's history with poor encryption policies, and vulnerability management. To be fair, Nest Cam's Indoor and Outdoor Security Cameras and Google Home also fell into the "Very Creepy" category -- and so did Amazon's Echo smart speakers. (The Amazon Echo Show even made it into Mozilla's highest "Super Creepy" category, where the only other product was Facebook Portal.) But at least the Nest Hello Video doorbell only appears in Mozilla's "Somewhat Creepy" category. "Just because something on your wishlist this year connects to the internet, doesn't mean you have to compromise on privacy and security..." warns the editor of Mozilla's Internet Health Report. And in addition, "Fitness trackers designed for kids as young as 4 years old, raise questions about what we are teaching our children about how much digital surveillance in their lives is normal." Going forward, they suggest that we push for better privacy regulations -- and that whenever we rate products on performance and price, we should also rate them on their privacy and security. But in the meantime, as Mozilla explained on Twitter, "Friends don't let friends buy creepy gifts."' -- source: https://yro.slashdot.org/story/19/11/25/0415202 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/

Web Creator Tim Berners-Lee Launches Plan To 'Fix' the Internet
by Peter Reutemann 26 Nov '19

26 Nov '19

'Tim Berners-Lee, the creator of the World Wide Web, is officially launching his plan to "fix" the internet. From a report: The World Wide Web Foundation, a non-profit campaign group set up by Berners-Lee, has secured the backing of tech giants Facebook, Google and Microsoft for the scheme, dubbed the "contract for the web." The British computer scientist first outlined his vision to overhaul organizations' approach to the internet at the Web Summit event last year. At the time, he said the web was "at a tipping point." The contract calls on companies to respect consumers' data privacy and urges governments to ensure everyone has access to the internet. "Never before has the web's power for good been more under threat," Adrian Lovett, CEO of the World Wide Web Foundation, told CNBC in an interview Friday. He added that the rise of hateful content and fake news being propagated online meant something had to change. "We're launching the contract for the web for the world's first-ever global action plan to protect the web as a force for good, bringing together companies, governments and citizens from around the world to say these are the things that need to be done to put things back on the right track." Other organizations backing the contract include DuckDuckGo, Reddit, GitHub and Reporters Without Borders. One major component of the pledge is the requirement that the web remains an accessible tool for all users. Lovett said that, "despite the progress we've seen in getting the world connected, half the world doesn't have access." He said the contract comes with nine core principles, while underneath them is a total of 76 clauses. "Not every organization has to abide by all of them," he insisted. "A good number of those 76 will be relevant." Berners-Lee will deliver a speech in Berlin, Germany, on Monday where he is due to say the contract will serve as a blueprint for governments, companies and citizens to safeguard the web as a force for good. The World Wide Web Foundation says it is working with partners to develop tools that can measure progress on the contract's various clauses' -- source: https://yro.slashdot.org/story/19/11/25/1347233 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/

Zorin OS 15 Lite Linux Distro Can Rejuvenate Your Aging Windows PC
by Peter Reutemann 26 Nov '19

26 Nov '19

'Called "Zorin OS 15 Lite," it is not only lightweight, but thanks to the Xfce desktop environment and integrated Flatpak support, it should be quite familiar to those switching from Windows. In fact, the developers are intentionally targeting existing Windows 7 users, as Microsoft's operating system will be unsupported beginning January 2020. Zorin OS 15 Lite, in comparison, is based on Ubuntu 18.04 LTS and supported until 2023! It even comes with the very modern Linux kernel 5.0. "With Zorin OS 15 Lite, weâ(TM)ve condensed the full Zorin OS experience into a streamlined operating system, designed to run fast on computers as old as 15 years. With version 15, we've gone the extra mile to make the XFCE 4.14-based desktop feel familiar and user-friendly to new users, especially those moving away from Windows 7 leading up to the end of its support in January 2020. By pairing the most advanced and efficient software with a user-friendly experience, we've made it possible for anyone to extend the lifespan of their computers for years to come," explains the Zorin OS developers.' -- source: https://linux.slashdot.org/story/19/11/25/179256 Maybe worth a demo next year?

The RIPE NCC Has Run Out of IPv4 Addresses
by Peter Reutemann 26 Nov '19

26 Nov '19

'The RIPE NCC, the regional internet registry for Europe, West Asia, and the former USSR, has allocated the final /22 remaining in their address pool, and has stated that they have now run out of IPv4 addresses. RIPE will continue to recover IPv4 addresses from organisations that go out of business, close, or that return them due to lack of need, but expects these small amounts of recovered IPv4 addresses to fall well short of demand: RIPE will now only assign IPv4 addresses to entities that have never received any IPv4 allocation in the past, and even then will assign no more than a /24. RIPE puts out a call to action for IPv6 migration: This event is another step on the path towards global exhaustion of the remaining IPv4 addressing space. In recent years, we have seen the emergence of an IPv4 transfer market and greater use of Carrier Grade Network Address Translation (CGNAT) in our region. There are costs and trade-offs with both approaches and neither one solves the underlying problem, which is that there are not enough IPv4 addresses for everyone. Without wide-scale IPv6 deployment, we risk heading into a future where the growth of our Internet is unnecessarily limited — not by a lack of skilled network engineers, technical equipment or investment -- but by a shortage of unique network identifiers. There is still a long way to go, and we call on all stakeholders to play their role in supporting the IPv6 roll-out.' -- source: https://tech.slashdot.org/story/19/11/25/1841256 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 5.4 Released
by Peter Reutemann 26 Nov '19

26 Nov '19

'Linux 5.4 has been released, featuring the new kernel lockdown mode, intended to strengthen the boundary between UID 0 and the kernel; virtio-fs, a high-performance virtio driver which allows a virtualized guest to mount a directory that has been exported on the host; fs-verity, for detecting file tampering, like dm-verity, but works on files rather than block devices; dm-clone, which allows live cloning of dm targets; two new madvise() flags for improved app memory management on Android, support for new Intel/AMD GPUs, support for the exfat file system and removing the experimental status of the erofs file system; a new haltpoll cpuidle driver and governor that greatly improves performance for virtualized guests wanting to do guest-side polling in the idle loop; and blk-iocost, a new cgroup controller that attempts to calculate more accurately the cost of IO. As always, many other new drivers and improvements can be found in the changelog.' -- source: https://tech.slashdot.org/story/19/11/25/1836212 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/

NextCloud Linux Servers Targetted by NextCry Ransomware
by Peter Reutemann 25 Nov '19

25 Nov '19

'A new and particularly troublesome ransomware variant has been identified in the wild. Dubbed NextCry, this nasty strain of ransomware encrypts data on NextCloud Linux servers and has managed to evade the detection of public scanning platforms and antivirus engines. To make matters worse, there is currently no free decryption tool available for victims. Ransomware hunter and creator of ID Ransomware Michael Gillespie notes that the NextCry ransomware, which is a Python script compiled in a Linux ELF binary using pyInstaller, oddly uses Base64 to encode file names as well as the content of files which have already been encrypted. Gillespie has also confirmed that NextCry encrypts data using the AES algorithm with a 256-bit key. The ransom note that NextCry victims receive reads "READ_FOR_DECRYPT", and demands 0.025 BTC for a victim's files to be unlocked.' -- source: https://linux.slashdot.org/story/19/11/24/1845253 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 Tracking Prevention in Microsoft's Edge Will Hit Google the Hardest
by Peter Reutemann 25 Nov '19

25 Nov '19

'Microsoft's Edge browser is built on the same open source code as Google Chrome. But Ed Bott, writing for ZDNet, noticed something interesting: On January 15, 2020, Microsoft is scheduled to roll out a completely revamped Edge browser to the general public. That browser, which is available for beta testing now on all supported versions of Windows and MacOS, includes a feature called Tracking Prevention. If that name sounds familiar, you're not imagining things. Microsoft added a Tracking Protection feature to Internet Explorer 9, back in 2011; it used simple text files called Tracking Protection Lists (TPLs) to allow or block third-party requests from specific domains. That's the same general principle behind Tracking Prevention in the new Edge, but the implementation is more usable and more sophisticated, with multiple Trust Protection Lists taking the place of a single TPL. I've spent the past week looking closely at this feature... [A]lthough it's aimed at the online advertising and tracking industries in general, my tests suggest that its effects are likely to be felt most directly by one company: Google. Using the default Balanced setting, Tracking Prevention blocked a total of 2,318 trackers, or an average of 35 on each page. Of that total, 552 were from Google domains. That's a mind-boggling 23.8% of the total. To put that into perspective, the second entry on the list of blocked trackers was Facebook, which represented 3.8% of the total. Rather than an anti-Google conspiracy, the article suggests this is instead just a reflection of both Google's ubiquity and its business model. "Google Analytics and Google AdSense are embedded on a staggering number of web pages."' -- source: https://tech.slashdot.org/story/19/11/24/2055219 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/
