Samsung Galaxy S10 Facial Recognition Fooled by a Video of the Phone Owner
by Peter Reutemann 11 Mar '19

11 Mar '19

'Experts have proven once again that facial recognition on modern devices remains hilariously insecure and can be bypassed using simple tricks such as showing an image or a video in front of a device's camera. From a report: The latest device to fall victim to such attacks is Samsung Galaxy S10, Samsung's latest top tier phone and considered one of the world's most advanced smartphones to date. Unfortunately, the Galaxy S10's facial recognition feature remains just as weak as the one supported in its previous versions or on the devices of its competitors, according to Lewis Hilsenteger, a smartphone reviewer better known as Unbox Therapy on YouTube. Hilsenteger showed in a demo video uploaded on his YouTube channel last week how putting up a video of the phone owner in front of the Galaxy S10 front camera would trick the facial recognition system into unlocking the device.' -- source: https://mobile.slashdot.org/story/19/03/11/166239 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/

EU's Plan To Ban Sale of User-Moddable RF Devices Draws Widespread Condemnation
by Peter Reutemann 11 Mar '19

11 Mar '19

'The Register is reporting that the EU is looking to block users from tinkering the firmware/software of their RF devices. This seems to have been very under reported, with a fairly short consultation period that has now expired. It could force manufacturers to lock down phones and routers etc to stop you from installing the likes of Lineage OS or OpenWRT. The way this is written it could stop devices like laptops or Raspberry Pi's having their software changed. >From the report: The controversy centres on Article 3(3)(i) of the EU Radio Equipment Directive, which was passed into law back in 2014. However, an EU working group is now about to define precisely which devices will be subject to the directive -- and academics, researchers, individual "makers" and software companies are worried that their activities and business models will be outlawed. Article 3(3)(i) states that RF gear sold in the EU must support "certain features in order to ensure that software can only be loaded into the radio equipment where the compliance of the combination of the radio equipment and software has been demonstrated." If the law is implemented in its most potentially harmful form, no third-party firmware could be installed onto something like a home router, for example.' -- source: https://tech.slashdot.org/story/19/03/11/1835239 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/

Debian Package Maintainer Steps Down, Complaining About 'Old Infrastructure'
by Peter Reutemann 11 Mar '19

11 Mar '19

'Michael Stapelberg, maintains "a bunch" of Debian packages and services, and says the free software Linux distro "has been in my life for well over 10 years at this point." Today he released a 2,255-word essay explaining why he's "winding down" his involvement in Debian to a minimum, citing numerous complaints including Debian's complicated build stack, waits of up to seven hours before package uploads can be installed, leading to "asynchronous" feedback -- and Debian's lack of tooling for large changes. The closest to "sending out a change for review" is to open a bug report with an attached patch... Culturally, reviews and reactions are slow. There are no deadlines. I literally sometimes get emails notifying me that a patch I sent out a few years ago (!!) is now merged. This turns projects from a small number of weeks into many years, which is a huge demotivator for me. Interestingly enough, you can see artifacts of the slow online activity manifest itself in the offline culture as well: I don't want to be discussing systemd's merits 10 years after I first heard about it. Lastly, changes can easily be slowed down significantly by holdouts who refuse to collaborate. My canonical example for this is rsync, whose maintainer refused my patches to make the package use debhelper purely out of personal preference. Granting so much personal freedom to individual maintainers prevents us as a project from raising the abstraction level for building Debian packages, which in turn makes tooling harder. There's also several complaints about old infrastructure -- for example, "I dread interacting with the Debian bug tracker. debbugs is a piece of software (from 1994) which is only used by Debian and the GNU project these days." Stapelberg also complains that the "painful" experience of developing using Debian "leaves a lot to be desired," and adds that "It baffles me that in 2019, we still don't have a conveniently browsable threaded archive of mailing list discussions." "My frustration level ultimately exceeded the threshold," Stapelberg writes in the essay, adding "I hope this post inspires someone, ideally a group of people, to improve the developer experience within Debian." He'll soon transition packages to be team-maintained "where it makes sense," but also "orphan packages where I am the sole maintainer... For all intents and purposes, please treat me as permanently on vacation..." "I will try to keep up best-effort maintenance of the manpages.debian.org service and the codesearch.debian.net service, but any help would be much appreciated."' -- source: https://linux.slashdot.org/story/19/03/10/2245221 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 Fine And Ancient Art Of Letterlocking
by Lawrence D'Oliveiro 07 Mar '19

07 Mar '19

Came across this linked from computer security expert Bruce Schneier’s blog: how did people in pre-industrial times protect paper letters from prying eyes? There were no mass-produced envelopes in those days, so they resorted to “letterlocking” -- intricate ways of folding and sealing a letter to form its own envelope <https://www.atlasobscura.com/articles/what-did-people-do-before-envelopes-l…>. And yes, there is a whole website devoted to this: <http://letterlocking.org/>.

Researchers Uncover Ring of GitHub Accounts Promoting 300+ Backdoored Apps
by Peter Reutemann 05 Mar '19

05 Mar '19

'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/

by Peter Reutemann 04 Mar '19

04 Mar '19

'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/
