Firefox Send Lets You Share 1GB Files With No Strings Attached
by Peter Reutemann 13 Mar '19

13 Mar '19

'In 2017, Mozilla experimented with a service that let you transfer 1GB files by sharing a web address with the recipient. Firefox Send is now out of testing and boasts a magnified 2.5GB file-size limit if you log into your Firefox account. From a report: Firefox Send is handy for those moments when you need to share video, audio or photo files that can be too big to squeeze into an email attachment. [...] Firefox Send, which will also be available as an Android app, illustrates one of Mozilla's efforts to diversify beyond the Firefox browser. Mozilla touts Firefox Send as focusing on privacy and uses encryption to protect files. Firefox Send files are available for up to seven days and can be password-protected. You can also limit the number of times they're downloaded.' -- source: https://hardware.slashdot.org/story/19/03/12/1439222 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/

Russia Blocks Encrypted Email Provider ProtonMail
by Peter Reutemann 12 Mar '19

12 Mar '19

'Russia has told internet providers to enforce a block against encrypted email provider ProtonMail, the company's chief has confirmed. The block was ordered by the state Federal Security Service, formerly the KGB, according to a Russian-language blog, which obtained and published the order after the agency accused the company and several other email providers of facilitating bomb threats. Several anonymous bomb threats were sent by email to police in late January, forcing several schools and government buildings to evacuate. In all, 26 internet addresses were blocked by the order, including several servers used to scramble the final connection for users of Tor, an anonymity network popular for circumventing censorship. Internet providers were told to implement the block "immediately," using a technique known as BGP blackholing, a way that tells internet routers to simply throw away internet traffic rather than routing it to its destination. But the company says while the site still loads, users cannot send or receive email. The way the KGB blocked ProtonMail is "particularly sneaky," ProtonMail chief executive Andy Yen said. "ProtonMail is not blocked in the normal way, it's actually a bit more subtle. They are blocking access to ProtonMail mail servers. So Mail.ru -- and most other Russian mail servers -- for example, is no longer able to deliver email to ProtonMail, but a Russian user has no problem getting to their inbox." "That's because the two ProtonMail servers listed by the order are its back-end mail delivery servers, rather than the front-end website that runs on a different system," adds TechCrunch.' -- source: https://yro.slashdot.org/story/19/03/12/0329259 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/

Anyone have an iso file for Knoppix 8.5, or know of a source for download? This appears to be the latest version, but so far is apparently only available with a copy of Linux Magazine linked with a Linux event in Germany. ~ Ian Y

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/
