CERN Ditches Microsoft to 'Take Back Control' With Open Source Software
by Peter Reutemann 14 Jun '19

14 Jun '19

'CERN is best known for pushing the boundaries of science and understanding, but the famed research outfit's next major experiment will be with open-source software. From a report: The European Organization for Nuclear Research, better known as CERN, and also known as home of the Large Hadron Collider, has announced plans to migrate away from Microsoft products and on to open-source solutions where possible. Why? Increases in Microsoft license fees. Microsoft recently revoked the organisations status as an academic institution, instead pricing access to its services on users. This bumps the cost of various software licenses 10x, which is just too much for CERN's budget' -- source: https://news.slashdot.org/story/19/06/12/1839213 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/

'After being ripped to shreds by angry users, Google engineers have promised this week that the upcoming changes to Chrome's extensions system won't cripple ad blockers, as everyone is fearing. Instead, the company claims that the new extension API changes will actually improve user privacy and bring speed improvements.

'The System76 Gazelle laptop is finally available. From a report: What makes this laptop so special (besides its pre-installed Linux-based operating System), is its impressive specifications. You see, System76 has supercharged it with a 9th generation Intel Core i7 Processor (9750H) and NVIDIA GTX 16-Series Graphics. It even has something the pricey MacBook Pro doesn't -- the ability to be configure with up to 64GB. Yeah, Apple's laptop can only have a maximum of 32GB. The Gazelle can be configured with additional top specs, such as an NVMe SSD up to 2TB. Actually, it can accommodate two such drives, so you can theoretically have 4TB of speedy storage. You can opt for either a 15 or 17-inch display, both of which have a 1080p resolution. Regardless of screen size, you get a full keyboard too, meaning it has a number pad on the right. It ships with Ubuntu or Pop!_OS pre-installed and starts at $1099.' -- source: https://hardware.slashdot.org/story/19/06/13/189249 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/

Yubico To Replace Vulnerable YubiKey FIPS Security Keys
by Peter Reutemann 13 Jun '19

13 Jun '19

'Yubico said today it plans to replace certain hardware security keys because of a firmware flaw that reduces the randomness of cryptographic keys generated by its devices. From a report: Affected products include models part of the YubiKey FIPS Series, a line of YubiKey authentication keys certified for use on US government networks (and others) according to the US government's Federal Information Processing Standards (FIPS). According to a Yubico security advisory published today, YubiKey FIPS Series devices that run firmware version 4.4.2 and 4.4.4 contain a bug that keeps "some predictable content" inside the device's data buffer after the power-up operation. This "predictable content" will influence the randomness of cryptographic keys generated on the device for a short period after the boot-up, until the "predictable content" is all used up, and true random data is present in the buffer. This means that for a short period after booting up YubiKey FIPS Series devices with the affected 4.4.2 and 4.4.4 versions will generate keys that can be either recovered partially, or in full, depending on the cryptographic algorithm the key is working with for a particular authentication operation.' -- source: https://tech.slashdot.org/story/19/06/13/1844232 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/

If you haven’t patched Vim or NeoVim text editors, you really, really should
by Peter Reutemann 13 Jun '19

13 Jun '19

'A recently patched vulnerability in text editors preinstalled in a variety of Linux distributions allows hackers to take control of computers when users open a malicious text file. The latest version of Apple’s macOS is continuing to use a vulnerable version, although attacks only work when users have changed a default setting that enables a feature called modelines. Vim and its forked derivative, NeoVim, contained a flaw that resided in modelines. This feature lets users specify window dimensions and other custom options near the start or end of a text file. While modelines restricts the commands available and runs them inside a sandbox that’s cordoned off from the operating system, researcher Armin Razmjou noticed the source! command (including the bang on the end) bypassed that protection.' -- source: https://arstechnica.com/information-technology/2019/06/if-you-havent-patche… 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/

'RAMBleed' Rowhammer Attack Can Now Steal Data, Not Just Alter It
by Peter Reutemann 12 Jun '19

12 Jun '19

' A team of academics from the US, Austria, and Australia, has published new research today detailing yet another variation of the Rowhammer attack. From a report: The novelty in this new Rowhammer variety -- which the research team has named RAMBleed -- is that it can be used to steal information from a targeted device, as opposed to altering existing data or to elevate an attacker's privileges, like all previous Rowhammer attacks, have done in the past. [...] In a research paper [PDF] published today, academics unveiled RAMBleed, the first Rowhammer attack that can actively deduce and steal data from a RAM card. To do this, researchers had to come up and combine different techniques, which, when assembled, would permit a RAMBleed attack to take place.' -- source: https://tech.slashdot.org/story/19/06/11/1931214 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 Biggest Data Breach Archive On the Internet Is For Sale
by Peter Reutemann 12 Jun '19

12 Jun '19

'Troy Hunt, the owner and founder of the well-known and respected data breach notification website "Have I Been Pwned," announced today that he's actively looking for a buyer. "To date, every line of code, every configuration and every breached record has been handled by me alone. There is no 'HIBP team,' there's one guy keeping the whole thing afloat," Hunt wrote. "It's time for HIBP to grow up. It's time to go from that one guy doing what he can in his available time to a better-resourced and better-funded structure that's able to do way more than what I ever could on my own." Motherboard reports: Over the years, Have I Been Pwned has become the repository for data breaches on the internet, a place where users can search for their email address and see whether they have been part of a data breach. It's now also a service where people can sign up to get notified whenever their accounts get breached. It's perhaps the most useful, free, cybersecurity service in the world. Hunt said he's already had informal conversations with some organizations that might be interested in buying the service. Hunt said he's engaged the financial consulting firm KPMG to look for a buyer. In the post, Hunt shared some staggering numbers that explain just how big Have I Been Pwned has become: 8 billion breached records, nearly 3 million people subscribed to notifications, who have been emailed about a breach 7 million times, 150,000 unique visitors to the site on a normal day, 10 million on an abnormal day. Regardless of who buys the site, Hunt made a series of commitments on the future of Have I Been Pwned: searches should remain free for consumers, the platform should expand and grow, and, finally, he wants to stay involved in some capacity.

Security Is Always Down To The Weakest Link
by Lawrence D'Oliveiro 11 Jun '19

11 Jun '19

Nice non-paywalled report <https://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=12235615> into how the National Party (and others) were able to obtain supposedly-confidential details of today’s Budget announcements. In summary, a “clone” was made of the Treasury website, containing the Budget info, that was supposed to be swapped for the current production site later today. It was not publicly accessible, at least directly. However, the search function on the public site was inadvertently sucking up the confidential info from the clone server as well, and carefully-worded searches would reveal bits of such info as search context, even if the actual documents being indexed were not accessible in full. The Police have decided that, even though such leaks are considered a serious matter, the accesses were “not unlawful”. Which seems a refreshing change from, say, the UK, where someone was prosecuted and jailed some years ago just for putting “../” into a URL ...

Large 'GoldBrute' RDP Botnet Hunts For Exposed Servers With Weak Passwords
by Peter Reutemann 08 Jun '19

08 Jun '19

'The Internet Storm Center reports: RDP, the remote desktop protocol, made the news recently after Microsoft patched a critical remote code execution vulnerability (CVE-2019-0708). While the reporting around this "Bluekeep" vulnerability focused on patching vulnerable servers, exposing RDP to the Internet has never been a good idea. Botnets have been scanning for these servers and are using weak and reused passwords to gain access to them. The latest example of such a botnet is an ongoing malicious campaign we are refering to as "GoldBrute". This botnet is currently brute forcing a list of about 1.5 million RDP servers exposed to the Internet... Each bot will only try one particular username and password per target. This is possibly a strategy to fly under the radar of security tools as each authentication attempt comes from different addresses. Long-time Slashdot reader UnderAttack writes: Infected systems will retrieve target lists from the command and control server and attempt to brute force credentials against the list, while at the same time looking for more exposed servers. With all the attention spent on patching RDP servers for the recent "BlueKeep" vulnerability, users should also make sure to just not expose RDP in the first place. Even patched, it will still be susceptible to brute forcing.' -- source: https://it.slashdot.org/story/19/06/08/0322234 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 MATE 19.10 Is Ditching VLC for GNOME MPV

Better desktop integration. That's according to Ubuntu MATE's Martin Wimpress who revealed news of the swap in the latest Ubuntu MATE monthly update on Patreon: "We will be dropping VLC from the pre-installed applications and shipping GNOME MPV instead. GNOME MPV will soon be renamed to Celluloid. The reasons for switching to GNOME MPV are similar to swapping out Thunderbird for Evolution; better desktop integration." Size is another factor. GNOME MPV takes up a comparatively svelte 27MB on the ISO image, whereas Qt5-based VLC requires closer to 70MB.' -- source: https://news.slashdot.org/story/19/06/06/1840240 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 Ambitious Plan To Reinvent How Websites Get Their Names
by Peter Reutemann 06 Jun '19

06 Jun '19

'When you type in a URL to your browser and press "enter," your browser sends that name to a network of computers called the Domain Name System (DNS), which converts it into IP addresses. These numbers are what allow your browser to find the right server on the internet and connect to it. When you navigate to a website, you are trusting a handful of organizations that have been charged with keeping the DNS working and secure. "To people like Steven McKie, a developer for and investor in an open-source project called the Handshake Network, this centralized power over internet naming makes the internet vulnerable to both censorship and cyberattacks," reports MIT technology review. "Handshake wants to decentralize it by creating an alternative naming system that nobody controls. In doing so, it could help protect us from hackers trying to exploit the DNS's security weaknesses, and from governments hoping to use it to block free expression." From the report: The system would be based on blockchain technology, meaning it would be software that runs on a widely distributed network of computers. In theory, it would have no single point of failure and depend on no human-run organization that could be corrupted or co-opted. Handshake's software is a heavily modified version ("fork") of Bitcoin, and just as Bitcoin's network of miners protects the cryptocurrency from manipulation and makes it virtually impossible for authorities to shut down, a similar network could keep a permanent, censorship-resistant record of internet names. The Handshake team is far from the first to try to create a decentralized naming system for the web. But unlike previous efforts, Handshake isn't trying to replace DNS but work with it. Besides ICANN, there's yet another class of organization whose job Handshake aims to decentralize. See that little padlock icon in your browser bar, to the left of the domain name? That means your computer has verified that your connection to this website is encrypted and that the site is authentic, not a fake one designed by a criminal trying to steal your login credentials. It does that by checking the veracity of a string of numbers called the site's digital certificate, issued by one of a number of so-called certificate authorities. These entities, many of which are for-profit companies, are crucial to internet security. They can also get hacked. And if one gets breached, and an attacker can start issuing fake certificates, it undermines the security of the whole internet. But if website names are managed on a tamper-resistant blockchain, then you don't need certificate authorities; the naming system itself can provide the guarantee that the site you're connected to is real. That's what Handshake aims to do.

New RCE Vulnerability Impacts Nearly Half of the Internet's Email Servers
by Peter Reutemann 06 Jun '19

06 Jun '19

'A critical remote command execution (RCE) security flaw impacts over half of the Internet's email servers, security researchers from Qualys have revealed today. The vulnerability affects Exim, a mail transfer agent (MTA), which is software that runs on email servers to relay emails from senders to recipients. According to a June 2019 survey of all mail servers visible on the Internet, 57% (507,389) of all email servers run Exim -- although different reports would put the number of Exim installations at ten times that number, at 5.4 million. In a security alert shared with ZDNet earlier today, Qualys, a cyber-security firm specialized in cloud security and compliance, said it found a very dangerous vulnerability in Exim installations running versions 4.87 to 4.91. The vulnerability is described as a remote command execution -- different, but just as dangerous as a remote code execution flaw -- that lets a local or remote attacker run commands on the Exim server as root. Qualys said the vulnerability can be exploited instantly by a local attacker that has a presence on an email server, even with a low-privileged account. lBut the real danger comes from remote hackers exploiting the vulnerability, who can scan the internet for vulnerable servers, and take over systems. The vulnerability was patched with Exim 4.92, on February 10, 2019, "but at the time the Exim team released v4.92, they didn't know they fixed a major security hole," reports ZDNet. "This was only recently discovered by the Qualys team while auditing older Exim versions. Now, Qualys researchers are warning Exim users to update to the 4.92 version to avoid having their servers taken over by attackers."' -- source: https://it.slashdot.org/story/19/06/06/0046234 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/

Chrome 75 Released With Web Share API File Support, Numeric Separators and Secret Reader Mode
by Peter Reutemann 05 Jun '19

'Google this week released Chrome 75 for Windows, Mac, Linux, Android, and iOS. The release includes hint for low latency canvas contexts, files supported in the Web Share API, numeric separators, and more developer features. [...] Next, files are now supported by the Web Share API. For years, Google has been working to bring native sharing capabilities to the web. The Web Share API allows web apps to invoke the same share dialog box as a native app. The implementation brings a new method and a new shareData property. Numeric literals now allow underscores (_, U+005F) as separators to make them more readable. Underscores can only appear between digits, and consecutive underscores are not allowed. There is also a reader mode that is not enabled by default. From a report: The big feature included with Chrome 75 is the addition of a hidden Reader Mode, similar to the one included with Firefox. This new Reader Mode is not active by default and must be turned on using one of Google Chrome's experimental flags -- which until recently has only been available in the Chrome Canary distribution. To enable and test Chrome's new Reader Mode, users must visit the chrome://flags/#enable-reader-mode section, and enable the Reader Mode option, as in the screenshot below. Chrome for Android includes these two features: 1. Generate strong and unique passwords with Chrome's built-in password manager. 2. Quickly look up your passwords by tapping any password field and using the new keyboard option.' -- source: https://tech.slashdot.org/story/19/06/05/1357233 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/

238 Google Play apps with >440 million installs made phones nearly unusable

'If the prevalence of abusive Google Play apps has left you numb, this latest report is for you. Carefully concealed adware installed in Google-approved apps with more than 440 million installations was so aggressive that it rendered mobile devices nearly unusable, researchers from mobile security provider Lookout said Tuesday. BeiTaAd, as the adware is known, is a plugin that Lookout says it found hidden in emojis keyboard TouchPal and 237 other applications, all of which were published by Shanghai, China-based CooTek. Together, the 238 unique apps had a combined 440 million installs. Once installed, the apps initially behaved normally. Then, after a delay of anywhere between 24 hours and 14 days, the obfuscated BeiTaAd plugin would begin delivering what are known as out-of-app ads. These ads appeared on users' lock screens and triggered audio and video at seemingly random times or even when a phone was asleep.' -- source: https://arstechnica.com/information-technology/2019/06/238-google-play-apps… 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/

Bash will still be available, but Apple is signaling that developers should start moving to zsh on macOS Mojave or earlier in anticipation of bash eventually going away in macOS. Apple hasn't explained exactly why it's making this change, but bash isn't exactly a modern shell as it's implemented in macOS, and a switch to something less aging makes a lot more sense for the company. Apple is stuck using version 3.2 of bash that has been licensed under GPLv2, as newer versions are licensed under GPLv3. Apple has kept clear of using GPLv3 packages in macOS as the license is generally more restrictive to companies like Apple that sign their own code and it includes explicit patent grants, ' -- source: https://apple.slashdot.org/story/19/06/04/1645240 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/

'"While Linux-preloaded laptops have been available for years from smaller companies, and have represented a fraction of their own sales with the much-admired XPS 13 developer model, Dell now offers a range of Precision models pre-installed with Ubuntu Linux," writes Slashdot reader Freshly Exhumed. Phoronix reports: At the start of May Dell announced an Ubuntu Linux option for their entry-level ~$700 Precision laptop while now they are closing out May by offering up Ubuntu 18.04 LTS on their higher-tier Precision laptop models. Ubuntu Linux has landed for the rest of Dell's current generation Precision mobile workstation line-up with support for the Precision 5540, 7540, and 7740. The Precision 5540 offers options of Xeon E or 9th Gen Core CPUs with up to 64GB of RAM and options for a NVIDIA Quadro T2000. The Precision 7540/7740 meanwhile are more powerful mobile workstations with supporting up to 128GB of ECC RAM and latest generation processors. The Precision 7740 model can also accomodate NVIDIA Quadro RTX 5000 series graphics.

Advanced Linux backdoor found in the wild escaped AV detection
by Peter Reutemann 30 May '19

30 May '19

'Researchers say they’ve discovered an advanced piece of Linux malware that has escaped detection by antivirus products and appears to be actively used in targeted attacks. HiddenWasp, as the malware has been dubbed, is a fully developed suite of malware that includes a trojan, rootkit, and initial deployment script, researchers at security firm Intezer reported on Wednesday. At the time Intezer’s post went live, the VirusTotal malware service indicated Hidden Wasp wasn’t detected by any of the 59 antivirus engines it tracks, although some have now begun to flag it. Time stamps in one of the 10 files Intezer analyzed indicated it was created last month. The command and control server that infected computers report to remained operational at the time this article was being prepared. Some of the evidence analyzed—including code showing that the computers it infects are already compromised by the same attackers—indicated that HiddenWasp is likely a later stage of malware that gets served to targets of interest who have already been infected by an earlier stage. It’s not clear how many computers have been infected or how any earlier related stages get installed. With the ability to download and execute code, upload files, and perform a variety of other commands, the purpose of the malware appears to be to remotely control the computers it infects. That's different from most Linux malware, which exists to perform denial of service attacks or mine cryptocurrencies.' -- source: https://arstechnica.com/information-technology/2019/05/advanced-linux-backd… 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/

Chinese Military To Replace Windows OS Amid Fears of US Hacking
by Peter Reutemann 29 May '19

29 May '19

'Amidst an escalating trade war and political tensions with the US, Beijing officials have decided to develop a custom operating system that will replace the Windows OS on computers used by the Chinese military. From a report: The decision, while not made official through the government's normal press channels, was reported earlier this month by Canada-based military magazine Kanwa Asian Defence. Per the magazine, Chinese military officials won't be jumping ship from Windows to Linux but will develop a custom OS. Thanks to the Snowden, Shadow Brokers, and Vault7 leaks, Beijing officials are well aware of the US' hefty arsenal of hacking tools, available for anything from smart TVs to Linux servers, and from routers to common desktop operating systems, such as Windows and Mac. Since these leaks have revealed that the US can hack into almost anything, the Chinese government's plan is to adopt a "security by obscurity" approach and run a custom operating system that will make it harder for foreign threat actors -- mainly the US -- to spy on Chinese military operations.' -- source: https://news.slashdot.org/story/19/05/28/1613221 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/

W3C and WHATWG Sign Agreement To Collaborate on a Single Version of HTML and DOM
by Peter Reutemann 29 May '19

29 May '19

'W3C and the WHATWG signed an agreement today to collaborate on the development of a single version of the HTML and DOM specifications. >From a blog post: The Memorandum of Understanding jointly published as the WHATWG/W3C Joint Working Mode gives the specifics of this collaboration. This is the culmination of a careful exploration effective partnership mechanisms since December 2017 after the WHATWG adopted many shared features as their work-mode and an IPR policy. The HTML Working Group which we will soon recharter will assist the W3C community in raising issues and proposing solutions for the HTML and DOM specifications, and bring WHATWG Review Drafts to Recommendation. Motivated by the belief that having two distinct HTML and DOM specifications claiming to be normative is generally harmful for the community, and the mutual desire to bring the work back together, W3C and WHATWG agree to the following terms: W3C and WHATWG work together on HTML and DOM, in the WHATWG repositories, to produce a Living Standard and Recommendation/Review Draft-snapshots. WHATWG maintains the HTML and DOM Living Standards. W3C facilitates community work directly in the WHATWG repositories (bridging communities, developing use cases, filing issues, writing tests, mediating issue resolution). W3C stops independent publishing of a designated list of specifications related to HTML and DOM and instead will work to take WHATWG Review Drafts to W3C Recommendations.' -- source: https://tech.slashdot.org/story/19/05/28/1353243 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google's Chrome Becomes Web 'Gatekeeper' and Rivals Complain
by Peter Reutemann 28 May '19

28 May '19

'Few home-grown Google products have been as successful as Chrome. Launched in 2008, it has more than 63% of the market and about 70% on desktop computers, according to StatCounter data. Mozilla's Firefox is far behind, while Apple's Safari is the default browser for iPhones. Microsoft's Internet Explorer and Edge browsers are punchlines. From a report: Google won by offering consumers a fast, customizable browser for free, while embracing open web standards. Now that Chrome is the clear leader, it controls how the standards are set. That's sparking concern Google is using the browser and its Chromium open-source underpinnings to elbow out online competitors and tilt entire industries in its favor. Most major browsers are now built on the Chromium software code base that Google maintains. Opera, an indie browser that's been used by techies for years, swapped its code base for Chromium in 2013. Even Microsoft is making the switch this year. That creates a snowball effect, where fewer web developers build for niche browsers, leading those browsers to switch over to Chromium to avoid getting left behind. This leaves Chrome's competitors relying on Google employees who do most of the work to keep Chromium software code up to date. Chromium is open source, so anyone can suggest changes to it, but the majority of programmers who approve contributions are Google employees, and any major disagreements get settled by a small circle of senior Google employees. Chrome is so ascendant these days that web developers often don't bother to test their sites on competing browsers. Google services including YouTube, Docs and Gmail sometimes don't work as well on rival browsers, sending frustrated users to Chrome. Instead of just another ship slicing through the sea of the web, Chrome is becoming the ocean.' -- source: https://developers.slashdot.org/story/19/05/28/1845238 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/

Antergos Linux Has Been Discontinued
by Peter Reutemann 23 May '19

23 May '19

'An Arch Linux based distribution, Antergos, has been discontinued. The project's primary goal was to make Arch Linux available to a wider audience of users by providing a streamlined, user friendly experience including a safe place for users to communicate, learn, and help one another. There have been 931,439 unique downloads of Antergos Linux since 2014. The primary reason for ending support for it was that the developers no longer have enough free time to properly maintain the distribution. They came to this decision because they believe that continuing to neglect the project would be a huge disservice to the community. Taking this action now, while the project's code still works, provides an opportunity for interested developers to take what they find useful and start their own projects. For existing Antergos users: there is no need to worry about installed systems as they will continue to receive updates directly from Arch. Soon, an update will be released that will remove the Antergos repos from system along with any Antergos-specific packages that no longer serve a purpose due to the project ending. Once that is completed, any packages installed from the Antergos repo that are in the AUR will begin to receive updates from there.

Crowdfunded Android Console Ouya Will Be Shut Down On June 25th
by Peter Reutemann 23 May '19

23 May '19

'Razer, the gaming hardware manufacturing company that purchased Ouya's software assets in mid-2015, announced today that the crowdfunded Android console will cease functioning on June 25th. "That date will mark the unremarkable end of what began as a runaway Kickstarter success story: the inexpensive Ouya mini-console was powered by Android and introduced games such as TowerFall," reports The Verge. "But despite being positioned as the indie console, Ouya never quite took off after its $8.5 million crowdfunding campaign. The goal was to move Android's indie gaming scene to TV screens -- with exclusive Ouya-only titles mixed in -- but the execution didn't pan out." From the report: The hardware has been discontinued ever since Razer acquired Ouya's software assets in 2015. So it's somewhat surprising that the platform has continued to plod along for nearly four additional years. But that all ends next month. Accounts will be deactivated on June 25th. After that, Razer says "access to the Discover section will no longer be available. Games downloaded that appear in Play may still function if they do not require a purchase validation upon launch." But by and large, games on the Ouya platform will stop working after the cutoff date. Razer notes that some developers might choose to help their Ouya customers by activating the same game on some other platform (i.e., Google Play) where available following the shutdown. Razer's own Forge TV device will continue functioning as an Android TV set-top box, but the Forge TV games store is also going offline come the 25th. Part of Razer's thinking behind the Ouya acquisition was to propel its long-term Android TV gaming ambitions. The company has clearly shifted its priorities over the last few years, as indicated by the decision to finally shut down Ouya once and for all.' -- source: https://hardware.slashdot.org/story/19/05/22/2042225 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/

ARM Memo Tells Staff To Stop Working With Huawei
by Peter Reutemann 22 May '19

22 May '19

'UK-based chip designer ARM has told staff it must suspend business with Huawei, according to internal documents obtained by the BBC. ARM instructed employees to halt "all active contracts, support entitlements, and any pending engagementsâ with Huawei and its subsidiaries to comply with a recent US trade clampdown. From a report: ARM's designs form the basis of most mobile device processors worldwide. In a company memo, it said its designs contained "US origin technology." As a consequence, it believes it is affected by the Trump administration's ban. One analyst described the move, if it became long-term, as an "insurmountable" blow to Huawei's business. He said it would greatly affect the firm's ability to develop its own chips, many of which are currently built with ARM's underlying technology, for which it pays a licence.' -- source: https://tech.slashdot.org/story/19/05/22/141215 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 and iOS Devices Impacted By New Sensor Calibration Attack
by Peter Reutemann 22 May '19

22 May '19

'A new device fingerprinting technique can track Android and iOS devices across the Internet by using factory-set sensor calibration details that any app or website can obtain without special permissions. From a report: This new technique -- called a calibration fingerprinting attack, or SensorID -- works by using calibration details from gyroscope and magnetometer sensors on iOS; and calibration details from accelerometer, gyroscope, and magnetometer sensors on Android devices. According to a team of academics from the University of Cambridge in the UK, SensorID impacts iOS devices more than Android smartphones. The reason is that Apple likes to calibrate iPhone and iPad sensors on its factory line, a process that only a few Android vendors are using to improve the accuracy of their smartphones' sensors. "Our approach works by carefully analysing the data from sensors which are accessible without any special permissions to both websites and apps," the research team said in a research paper published yesterday. "Our analysis infers the per-device factory calibration data which manufacturers embed into the firmware of the smartphone to compensate for systematic manufacturing errors [in their devices' sensors]," researchers said. This calibration data can then be used as a fingerprint, producing a unique identifier that advertising or analytics firms can use to track a user as they navigate across the internet.' -- source: https://it.slashdot.org/story/19/05/22/1852204 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/

decompressing large zip files

Hi there Once in a while, I get large zip files from clients. Since they are running Windows, their zip tool doesn't have the same 4GB limitation that the unzip command-line tool under Linux usually has. Today, I once again had to deal with a large file and had some time to look into a solution that wouldn't involve copying the file onto a Windows box for converting the archive. If you have p7zip-full installed, you can use: 7z x file.zip If you have Java installed, you can use: jar xf file.zip Found here: https://serverfault.com/questions/235139/how-to-unzip-files-bigger-than-4gb 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 67 Arrives With New Performance and Privacy Features, Voice Search Widget on Android

'Mozilla today launched Firefox 67 for Windows, Mac, Linux, and Android. From a report: The 10th release since Mozilla's big Firefox Quantum launch in November 2017 doubles down on performance and privacy. Firefox 67 includes deprioritizing least commonly used features, suspending unused tabs, faster startup, blocking of cryptomining and fingerprinting, Private Browsing improvements, voice input in the Android search widget, and more. [...] Firefox 67 is better at performing tasks at the optimal time, resulting in faster "painting" of the page. Specifically, the browser deprioritizes least commonly used features and delays set Timeout to prioritize scripts for things you need. Mozilla says Instagram, Amazon, and Google searches now execute between 40% and 80% faster. Firefox also now scans for alternative style sheets after page load and doesn't load the auto-fill module unless there is a form to complete. Next, Firefox 67 detects if your computer's memory is running low (under 400MB) and suspends unused tabs. If you do click on a tab that you haven't used or looked at in a while, it will reload where you left off. Finally, Firefox 67 promises faster startup for users that customized their browser with an add-on.' -- source: https://news.slashdot.org/story/19/05/21/1636224 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 Performance Hit 5x Harder Than AMD After Spectre, Meltdown Patches
by Peter Reutemann 21 May '19

21 May '19

'Phoronix has conducted a series of tests to show just how much the Spectre and Meltdown patches have impacted the raw performance of Intel and AMD CPUs. While the patches have resulted in performance decreases across the board, ranging from virtually nothing to significant depending on the application, it appears that Intel received the short end of the stick as its CPUs have been hit five times harder than AMD, according to ExtremeTech. From the report: The collective impact of enabling all patches is not a positive for Intel. While the impacts vary tremendously from virtually nothing to significant on an application-by-application level, the collective whack is about 15-16 percent on all Intel CPUs without Hyper-Threading disabled. Disabling increases the overall performance impact to 20 percent (for the 7980XE), 24.8 percent (8700K) and 20.5 percent (6800K). The AMD CPUs are not tested with HT disabled, because disabling SMT isn't a required fix for the situation on AMD chips, but the cumulative impact of the decline is much smaller. AMD loses ~3 percent with all fixes enabled. The impact of these changes is enough to change the relative performance weighting between the tested solutions. With no fixes applied, across its entire test suite, the CPU performance ranking is (from fastest to slowest): 7980XE (288), 8700K (271), 2990WX (245), 2700X (219), 6800K. (200). With the full suite of mitigations enabled, the CPU performance ranking is (from fastest to slowest): 2990WX (238), 7980XE (231), 2700X (213), 8700K (204), 6800K (159). In closing, ExtremeTech writes: "AMD, in other words, now leads the aggregate performance metrics, moving from 3rd and 4th to 1st and 3rd. This isn't the same as winning every test, and since the degree to which each test responds to these changes varies, you can't claim that the 2990WX is now across-the-board faster than the 7980XE in the Phoronix benchmark suite. It isn't. But the cumulative impact of these patches could result in more tests where Intel and AMD switch rankings as a result of performance impacts that only hit one vendor."' -- source: https://hardware.slashdot.org/story/19/05/20/228218 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/

>20, 000 Linksys routers leak historic record of every device ever connected
by Peter Reutemann 21 May '19

21 May '19

'This post has been updated to add comments Linksys made online, which says company researchers couldn't reproduce the information disclosure exploit on routers that installed a patch released in 2014. Representatives of Belkin, the company that acquired Linksys in 2013, didn't respond to the request for comment that Ars sent on Monday. Ars saw the statement only after this article went live. More than 20,000 Linksys wireless routers are regularly leaking full historic records of every device that has ever connected to them, including devices' unique identifiers, names, and the operating systems they use. The data can be used by snoops or hackers in either targeted or opportunistic attacks. Independent researcher Troy Mursch said the leak is the result of a flaw in almost three dozen models of Linksys routers. It took about 25 minutes for the Binary Edge search engine of Internet-connected devices to find 21,401 vulnerable devices on Friday. A scan earlier in the week found 25,617. They were leaking a total of 756,565 unique MAC addresses. Exploiting the flaw requires only a few lines of code that harvest every MAC address, device name, and operating system that has ever connected to each of them. The flaw allows snoops or hackers to assemble disparate pieces of information that most people assume aren’t public. By combining a historical record of devices that have connected to a public IP addresses, marketers, abusive spouses, and investigators can track the movements of people they want to track. The disclosure can also be useful to hackers. The Shadowhammer group, for instance, recently infected as many as 1 million people after hacking the software update mechanism of computer maker ASUS. The hackers then used a list of about 600 MAC addresses of specific targets that, if infected, would receive advanced stages of the malware.' -- source: https://arstechnica.com/information-technology/2019/05/33-linksys-router-mo… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Opera Reborn 3: No modern browser is perfect, but this may be as close as it gets
by Peter Reutemann 20 May '19

20 May '19

'When Opera Software unveiled a new look and feel for its browser earlier this year, the company made a big deal of the impending changes. "We put Web content at center stage," the Opera team declared on its blog. And early previews of the design appeared to be quite pared down, allowing users to browse "unhindered by unnecessary distractions" as the Opera team put it. Well Opera recently released what the company refers to as Reborn 3, the latest version of its flagship desktop browser, and it's tempting to dismiss the name as little more than marketing hype. But given the relentless and utterly unspectacular updates that the Chromium project releases every six weeks, it can also be hard to denote actual big releases of browsers based on Chromium—hence the "Reborn" moniker. After spending some time with Reborn 3, however, the name seems accurate. For Opera, this is a significant update that goes far beyond what arrived with the move to Chromium 60. Opera Reborn 3—or Opera 60 if you want to stick with version numbers—transitions a slew of features that recently debuted in Opera's mobile browsers to the desktop. The big three in this release are support for blockchain-secured transactions, a crypto wallet to go with the mobile version, and a new overall look with light and dark themes available. So if you haven't checked out Opera lately, it's worth revisiting, especially for those older Opera fans still smarting about the switch from Opera's Presto rendering engine to Google's Blink rendering engine.' -- source: https://arstechnica.com/information-technology/2019/05/review-opera-once-le… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Is The Global Internet Disintegrating?
by Peter Reutemann 20 May '19

20 May '19

''The global internet is disintegrating," argues BBC Future, calling Russia "one of a growing number of countries that has had enough of the Western-built, Western-controlled internet backbone...aided as much by advances in technology as by growing global misgivings about whether the open internet was ever such a good idea to start with." "The new methods raise the possibility not only of countries pulling up their own drawbridges, but of alliances between like-minded countries building on these architectures to establish a parallel internet..." It's DNS that Russia has been setting its sights on... The plan -- which was met with skepticism from much of the engineering community, if not dismissed outright -- was to create a Russia-only copy of the DNS servers (the internet's address book, currently headquartered in California) so that citizens' traffic would be exclusively directed to Russian sites, or Russian versions of external sites. It would send Russian internet users to Yandex if they typed in Google, or the social network VK instead of Facebook. To lay the groundwork for this, Russia spent years enacting laws that force international companies to store all Russian citizens' data inside the country -- leading some companies such as LinkedIn to be blocked when they refused to comply... According to estimates from the International Institute for Strategic Studies in London, China is now engaged in some 80 telecommunications projects around the world -- from laying cables to building core networks in other countries, contributing to a significant and growing Chinese-owned global network... One possibility is a scenario where enough countries join Russia and China to develop a similar infrastructure to a point where they could sustain each other economically without doing business with the rest of the world, meaning they could shut themselves off the Western internet. Smaller countries might prefer an internet built around a non-Western standard, and an economic infrastructure built around China might be the "third way" that allows countries to participate in a semi-global economy while being able to control certain aspects of their populations' internet experience. Maria Farrell of the Open Rights Group (an internet freedom organisation) tells BBC Future that "Nations like Zimbabwe and Djibouti, and Uganda, they don't want to join an internet that's just a gateway for Google and Facebook" to colonise their digital spaces. And there's also fears about western espionage. "Along with every other expert interviewed for this article, Farrell reiterated how unwise it would be underestimate the ongoing reverberations of the Snowden revelations..."' -- source: https://tech.slashdot.org/story/19/05/19/1652253 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 Ends Android Collaboration With Huawei. No Gmail, Play Store For Future Huawei Phones
by Peter Reutemann 19 May '19

19 May '19

'Alphabet Inc's Google has suspended business with Huawei that requires the transfer of hardware and software products except those covered by open source licenses, a source close to the matter told Reuters on Sunday, in a blow to the Chinese technology company that the U.S. government has sought to blacklist around the world. Huawei Technologies Co Ltd will immediately lose access to updates to the Android operating system, and the next version of its smartphones outside of China will also lose access to popular applications and services including the Google Play Store and Gmail app... Huawei will continue to have access to the version of the Android operating system available through the open source license that is freely open to anyone who wishes to use it. But Google will stop providing any technical support and collaboration for Android and Google services to Huawei going forward, the source said.' -- source: https://mobile.slashdot.org/story/19/05/19/1829216 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 Pushes Kotlin Over Java for Android Development
by Peter Reutemann 18 May '19

18 May '19

'Google "officially declared Kotlin the go-to language for Android development last week at its Google I/O developer conference," reports Mike Melanson's "This Week in Programming" column, "and the company is backing that up with a couple of initiatives around making it easier (and free) to learn the language now used by a majority of Android developers." Google teamed up with Udacity to offer Developing Android Apps with Kotlin , a free, self-paced online course on how to build Android apps with Jetpack and Kotlin, meant for people who have programming experience and are comfortable with Kotlin basics. Google also announced "Kotlin/Everywhere, a series of community-driven events focussing on the potential of Kotlin on all platforms," which it is putting on in conjunction with JetBrains. Of course, this leaves the question that has been asked many times before -- why Kotlin? -- and IT consultant Kristen Carter offers a take on how Android app development became Kotlin-first. Carter offers some business angles, such as the 2010 lawsuit against Google by Oracle, which predates Kotlin by just a year, and she speculates may have been the impetus behind the language's development as "Google has always wanted to get away from the [Java] ecosystem." At the same time, Carter offers some language-specific reasoning too, such as the comparably succinct nature of Kotlin, the absence of Java's NullPointerExceptions, and the ease with which Java developers could transition to Kotlin. Carter ends her piece by posing the possibility that Oracle "knows the significance of Java in android app development" and could "ship Java with a few upgrades in its next version to take on Kotlin."' -- source: https://developers.slashdot.org/story/19/05/17/2355248 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 John the Ripper Cracks Passwords On FPGAs
by Peter Reutemann 18 May '19

18 May '19

'Long-time Slashdot reader solardiz has long bring an advocate for bringing security to open environments. Wednesday he contacted Slashdot to share this update about a piece of software he's authored called John the Ripper: John the Ripper is the oldest still evolving password cracker program (and Open Source project), first released in 1996. John the Ripper 1.9.0-jumbo-1, which has just been announced with a lengthy list of changes, is the first release to include FPGA support (in addition to CPU, GPU, and Xeon Phi). This is a long-awaited (or long-delayed) major release, encompassing 4.5 years of development and 6000+ commits by 80+ contributors. From the announcement: "Added FPGA support for 7 hash types for ZTEX 1.15y boards [...] we support: bcrypt, descrypt (including its bigcrypt extension), sha512crypt & Drupal7, sha256crypt, md5crypt (including its Apache apr1 and AIX smd5 variations) & phpass. As far as we're aware, several of these are implemented on FPGA for the very first time. For bcrypt, our ~119k c/s at cost 5 in ~27W greatly outperforms latest high-end GPUs per board, per dollar, and per Watt. [...] We also support multi-board clusters (tested [...] for up to 16 boards, thus 64 FPGAs, [...] on a Raspberry Pi 2 host)' -- source: https://it.slashdot.org/story/19/05/18/1841245 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/

Severe Linux Kernel Flaw Found In RDS
by Peter Reutemann 18 May '19

18 May '19

'Linux systems running kernels prior to 5.0.8 require patching after news emerged of a high-severity flaw that could be remotely exploited. According to the NIST advisory, CVE-2019-1181 is a race condition affecting the kernel's rds_tcp_kill_sock in net/rds/tcp.c "leading to a use-after-free, related to net namespace cleanup." The RDS bit refers to systems running the Reliable Datagram Sockets (RDS) for the TCP module, which means only systems that run applications using this are affected. The attention-grabbing part is that this opens unpatched systems to remote compromise and denial of service without the need for system privileges or user interaction. On the other hand, the attack complexity is described as 'high', and any such attack would need to be launched from the local network.' -- source: https://linux.slashdot.org/story/19/05/18/2122204 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/
