'A security researcher has uncovered a ring of malicious GitHub accounts promoting over 300 backdoored Windows, Mac, and Linux applications and software libraries. The malicious apps contained code to gain boot persistence on infected systems and later download other malicious code -- which appeared to be a "sneaker bot," a piece of malware that would add infected systems to a botnet that would later participate in online auctions for limited edition sneakers. All the GitHub accounts that were hosting these files -- backdoored versions of legitimate apps -- have now been taken down. One account, in particular, registered in the name of Andrew Dunkins, hosted 305 backdoored ELF binaries. Another 73 apps were hosted across 88 other accounts.

Firefox Fears UAE Government's Cybersecurity Company 'DarkMatter' May Be Tied To a Cyber Espionage Program
by Peter Reutemann 05 Mar '19

05 Mar '19

'Firefox browser-maker Mozilla is considering whether to block cybersecurity company DarkMatter from serving as one of its internet security gatekeepers after a Reuters report linked the United Arab Emirates-based firm to a cyber espionage program. Reuters reported in January that DarkMatter provided staff for a secret hacking operation, codenamed Project Raven, on behalf of an Emirati intelligence agency. The unit was largely comprised of former U.S. intelligence officials who conducted offensive cyber operations for the UAE government. Former Raven operatives told Reuters that many DarkMatter executives were unaware of the secretive program, which operated from a converted Abu Dhabi mansion away from DarkMatter's headquarters. Those operations included hacking into the internet accounts of human rights activists, journalists and officials from rival governments, Reuters found. DarkMatter has denied conducting the operations and says it focuses on protecting computer networks. While Mozilla had been considering whether to grant DarkMatter the authority to certify websites as safe, two Mozilla executives said in an interview last week that Reuters' report raised concerns about whether DarkMatter would abuse that authority. Mozilla said the company has not yet come to a decision on whether to deny the authority to DarkMatter, but expects to decide within weeks.' -- source: https://news.slashdot.org/story/19/03/05/0424249 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/

All Intel Chips Open To New 'Spoiler' Non-Spectre Attack
by Peter Reutemann 05 Mar '19

05 Mar '19

'Spoiler is the newest speculative attack affecting Intel's micro-architecture. From a report: Like the Spectre and Meltdown attacks revealed in January 2018, Spoiler also abuses speculative execution in Intel chips to leak secrets. However, it targets a different area of the processor called the Memory Order Buffer, which is used to manage memory operations and is tightly coupled with the cache. Researchers from Worcester Polytechnic Institute, Massachusetts, and the University of Lubeck in north Germany detail the attack in a new paper, 'Spoiler: Speculative load hazards boost Rowhammer and cache attacks'. The paper [PDF] was released this month and spotted by The Register. The researchers explain that Spoiler is not a Spectre attack, so it is not affected by Intel's mitigations for it, which otherwise can prevent other Spectre-like attacks such as SplitSpectre.' -- source: https://it.slashdot.org/story/19/03/05/1524251 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 5.1 continues the massive undertaking in preparing the kernel for the Year 2038 problem. Phoronix: The Linux kernel has been seeing "Y2038" work for years and the effort is far from over. Thomas Gleixner (a Linux kernel developer who serves as a member of the technical advisory board at The Linux Foundation) sent in the latest Y2038 work for the Linux 5.1 kernel, which after a lot of ground work in previous kernels has introduced the first set of syscalls that are Year 2038 safe.' -- source: https://linux.slashdot.org/story/19/03/05/1929233 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/

Why 'ji32k7au4a83' is a Remarkably Common Password
by Peter Reutemann 05 Mar '19

05 Mar '19

'A seemingly complex set of characters like "ji32k7au4a83" is a very common password among users, it turns out. From a report: This interesting bit of trivia comes from self-described hardware/software engineer Robert Ou, who recently asked his Twitter followers if they could explain why this seemingly random string of numbers has been seen by Have I Been Pwned (HIBP) over a hundred times. Have I Been Pwned is an aggregator that was started by security expert Troy Hunt to help people find out if their email or personal data has shown up in any prominent data breaches. One service it offers is a password search that allows you to check if your password has shown up in any data breaches that are on the radar of the security community. In this case, "ji32k7au4a83" has been seen by HIBP in 141 breaches. Several of Ou's followers quickly figured out the solution to his riddle. The password is coming from the Zhuyin Fuhao system for transliterating Mandarin. The reason it's showing up fairly often in a data breach repository is because "ji32k7au4a83" translates to English as "my password."' -- source: https://it.slashdot.org/story/19/03/05/203253 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/

'Linus Torvalds has released Linux 5.0 in kicking off the kernel's 28th year of development. Linux 5.0 features include AMD FreeSync support, open-source NVIDIA Turing GPU support, Intel Icelake graphics, Intel VT-d scalable mode, NXP PowerPC processors are now mitigated for Spectre Variant Two, and countless other additions. eWeek adds: Among the new features that have landed in Linux 5.0 is support for the Adiantum encryption system, developed by Google for low power devices. Google's Android mobile operating system and ChromeOS desktop operating system both rely on the Linux kernel. "Storage encryption protects your data if your phone falls into someone else's hands," Paul Crowley and Eric Biggers, Android Security and Privacy Team at Google wrote in a blog post. "Adiantum is an innovation in cryptography designed to make storage encryption more efficient for devices without cryptographic acceleration, to ensure that all devices can be encrypted. Memory management in Linux also gets a boost in the 5.0 kernel with a series of improvements designed to help prevent memory fragmentation, which can reduce performance.' -- source: https://linux.slashdot.org/story/19/03/04/1329227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Researchers Break Digital Signatures For Most Desktop PDF Viewers
by Peter Reutemann 26 Feb '19

26 Feb '19

'A team of academics from the Ruhr-University Bochum in Germany say they've managed to break the digital signing system and create fake signatures on 21 of 22 desktop PDF viewer apps and five out of seven online PDF digital signing services. This includes apps such as Adobe Acrobat Reader, Foxit Reader, and LibreOffice, and online services like DocuSign and Evotrust --just to name the most recognizable names. The five-person research team has been working since early October 2018 together with experts from Germany's Computer Emergency Response Team (BSI-CERT) to notify impacted services. The team went public with their findings over the weekend after all affected app makers and commercial companies finished patching their products. In research published today, the Ruhr-University Bochum team described three vulnerabilities that they found in the digital signing process used by several desktop and web-based PDF signing services. Summarized, they are: 1. Universal Signature Forgery (USF) -- vulnerability lets attackers trick the signature verification process into showing users a fake panel/message that the signature is valid. 2. Incremental Saving Attack (ISA) -- vulnerability lets attackers add extra content to an already signed PDF document via the "incremental saving (incremental update)" mechanism, but without breaking the already-existing signature. 3. Signature Wrapping (SWA) -- vulnerability is similar to ISA, but the malicious code also contains extra logic to fool the signature validation process into "wrapping" around the attacker's extra content, effectively digitally signing the incremental update.' -- source: https://it.slashdot.org/story/19/02/25/2126208 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/

<https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=122073…>: Independent research commissioned by Vocus indicates "piracy is dying a natural death," ... ... Peer-to-peer services, usually associated with piracy, used to be "the dominant source of traffic on our network." Today, about 80 per cent of Vocus' peak-time traffic is for legal streaming sites like Netflix and YouTube. Ah, don’t you just love that simplistic conflation: P2P ≡ piracy, YouTube ≡ legit.

Android Is Helping Kill Passwords on a Billion Devices
by Peter Reutemann 25 Feb '19

25 Feb '19

'The FIDO Alliance -- a consortium that develops open source authentication standards -- has been pushing to expand its secure login protocols to make seamless logins a reality for several years. Today, it has hit the jackpot: Google. From a report: On Monday, Google and the FIDO Alliance announced that Android has added certified support for the FIDO2 standard, meaning that the vast majority of devices running Android 7 or later will now be able to handle password-less logins in mobile browsers like Chrome. Android already offered secure FIDO login options for mobile apps, where you authenticate using a phone's fingerprint scanner or with a hardware dongle like a YubiKey. But FIDO2 support will make it possible to use these easy authentication steps for web services in a mobile browser instead of laboriously typing in your password every time you want to log in. Web developers can now design their sites to interact with Android's FIDO2 management infrastructure.' -- source: https://tech.slashdot.org/story/19/02/25/1440241 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/
