System76 Will Begin Shipping 2 Linux Laptops With Coreboot-Based Open Source Firmware
by Peter Reutemann 10 Oct '19

10 Oct '19

'System76, the Denver-based Linux PC manufacturer and developer of Pop OS, has some stellar news for those who prefer their laptops a little more open. Later this month the company will begin shipping two of their laptop models with its Coreboot-powered open source firmware. >From a report: Beginning today, System76 will start taking pre-orders for both the Galago Pro and Darter Pro laptops. The systems will ship out later in October, and include the company's Coreboot-based open source firmware which was previously teased at the 2019 Open Source Firmware Conference. (Coreboot, formerly known as LinuxBIOS, is a software project aimed at replacing proprietary firmware found in most computers with a lightweight firmware designed to perform only the minimum number of tasks necessary to load and run a modern 32-bit or 64-bit operating system.) What's so great about ripping out the proprietary firmware included in machines like this and replacing it with an open alternative? To begin with, it's leaner. System76 claims that users can boot from power off to the desktop 29% faster with its Coreboot-based firmware. [...] Both of these laptops can be kitted out with 10th-Generation Intel CPUs (specifically the i5-10210U and the i7-10510U), and both have glare-resistant matte 1080p IPS displays. Beginning at $949, the Galago Pro features an all-aluminum chassis, a wealth of connectivity options including HDMI, DisplayPort to USB-C and Thunderbolt, and can be configured with up to 32GB of RAM and up to 6TB of storage space. The Darter Pro, meanwhile, can be built out with 32GB of RAM and up to 2TB of storage, and features up to 10 hours of battery life.' -- source: https://hardware.slashdot.org/story/19/10/10/1847228 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/

Forum cracks the vintage passwords of Ken Thompson and other Unix pioneers
by Peter Reutemann 10 Oct '19

10 Oct '19

'As one of the original versions of Unix, BSD is an ancient operating system. So it shouldn’t come as a surprise that it used what are, by today’s standards, strange, even ridiculous security. For one, the hashing function protecting passwords, though state of the art 40 years ago, is now trivial to crack. Stranger still, the password hashes of some BSD creators were included in publicly available source code. And then, there are the passwords people chose. Last week, technologist Leah Neukirchen reported finding a source tree for BSD version 3, circa 1980, and successfully cracking passwords of many of computing’s early pioneers. In most of the cases the success was the result of the users choosing easy-to-guess passwords. BSD co-inventor Dennis Ritchie, for instance, used “dmac” (his middle name was MacAlistair); Stephen R. Bourne, creator of the Bourne shell command line interpreter, chose “bourne”; Eric Schmidt, an early developer of Unix software and now the executive chairman of Google parent company Alphabet, relied on “wendy!!!” (the name of his wife); and Stuart Feldman, author of Unix automation tool make and the first Fortran compiler, used “axolotl” (the name of a Mexican salamander). Weakest of all was the password for Unix contributor Brian W. Kernighan: “/.,/.,”—representing a three-character string repeated twice using adjacent keys on a QWERTY keyboard. (None of the passwords included the quotation marks.) But there were at least five plaintext passwords that remained out of reach. They included those belonging to Turkish computer scientist Özalp Babaoğlu, Unix software developer Howard Katseff, and crucial Unix contributors Tom London and Bob Fabry. But the uncracked hash that seemed to occupy Neukirchen the longest was the password used by Ken Thompson, another Unix co-inventor. “I never managed to crack ken's password with the hash ZghOT0eRm4U9s, and I think I enumerated the whole 8 letter lowercase + special symbols key space,” Neukirchen reported in the above-linked thread, posted to the Unix Heritage Society mailing list. “Any help is welcome.' -- source: https://arstechnica.com/information-technology/2019/10/forum-cracks-the-vin… 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/

Schneier Slams Australia's Encryption Laws and CyberCon Speaker Bans
by Peter Reutemann 09 Oct '19

09 Oct '19

'Governments breaking encryption is bad, and "will get worse once breaking encryption means people can die," says one of the world's leading security experts. From a report: "Australia has some pretty draconian laws about forcing tech companies to break security," says cryptographer and computer security professional Bruce Schneier. He's referring to the controversial Telecommunications and Other Legislation Amendment (Assistance and Access) Act 2018, which came into force in December. "I actually don't like that, because stuff that you do flows downhill to the US. So stop doing that," he told the Australian Cybersecurity Conference, or CyberCon, in Melbourne on Wednesday. Schneier's argument against breaking encrypted communications is simple. "You have to make a choice. Either everyone gets to spy, or no one gets to spy. You can't have 'We get to spy, you don't.' That's not the way the tech works," he said. "As this tech becomes more critical to life, we simply have to believe, accept, that securing it is more important than leaving it insecure so you can eavesdrop on the bad guys."' -- source: https://it.slashdot.org/story/19/10/09/1855255 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/

Tor Project Removes 13.5% of Current Servers For Running EOL Versions
by Peter Reutemann 09 Oct '19

09 Oct '19

'The Tor Project has removed from its network this week more than 800 servers that were running outdated and end-of-life (EOL) versions of the Tor software. The removed servers represent roughly 13.5% of the 6,000+ servers that currently comprise the Tor network and help anonymize traffic for users across the world. Roughly 750 of the removed servers represent Tor middle relays, and 62 are exit relays -- where users exit the Tor network onto the world wide web after having their true location hidden through the Tor network. The organization said it plans to release a Tor software update in November that will natively reject connections with EOL Tor server versions by default, without any intervention from the Tor Project staff. "Until then, we will reject around 800 obsolete relays using their fingerprints," the Tor Project said in a statement this week.' -- source: https://tech.slashdot.org/story/19/10/09/1853238 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/

Critical Remote Code Execution Flaw Fixed In Popular Terminal App For MacOS
by Peter Reutemann 09 Oct '19

09 Oct '19

'iTerm2 users: It's time to upgrade. A security audit sponsored by the Mozilla Open Source Support Program uncovered a critical remote code execution (RCE) vulnerability in the popular open-source terminal app for macOS. ITerm2 is an open-source alternative to the built-in macOS Terminal app, which allows users to interact with the command-line shell. Terminal apps are commonly used by system administrators, developers and IT staff in general, including security teams, for a variety of tasks and day-to-day operations. The iTerm2 app is a popular choice on macOS because it has features and allows customizations that the built-in Terminal doesn't, which is why the Mozilla Open Source Support Program (MOSS) decided to sponsor a code audit for it. The MOSS was created in the wake of the critical and wide-impact Heartbleed vulnerability in OpenSSL with the goal of sponsoring security audits for widely used open-source technologies. The flaw, which is now tracked as CVE-2019-9535, has existed in iTerm2 for the past seven years and is located in the tmux integration. Tmux is a terminal multiplexer that allows running multiple sessions in the same terminal window by splitting the terminal screen. The flaw was fixed in iTerm2 version 3.3.6, which was released today.' -- source: https://apple.slashdot.org/story/19/10/09/2048214 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/

Essential Reveals Project Gem Smartphone With Very Long, Unusual Design
by Peter Reutemann 09 Oct '19

09 Oct '19

'Andy Rubin, the controversial mobile industry executive who co-founded Android, left Google amid allegations of sexual misconduct while retaining a huge severance package, and went on to create the Essential Phone, has tweeted photos teasing an upcoming device with an elongated design and very tall UI composed of card-like apps. The Verge reports: It look extremely small in his hands, too. The device has a large button and volume rocker on the right edge and a fingerprint divot around back, below what appears to be a single main camera. And as you can see, these devices have some decidedly flashy finishes that change color when you view them at different angles -- a sea green that shifts to yellow and blue, for example. An Essential spokesperson confirmed to the The Verge that this is the company's new phone, adding: "We've been working on a new device that's now in early testing with our team outside the lab. We look forward to sharing more in the near future." A couple hours later, Essential tweeted some slightly more official images of the new phone, which it's calling Project Gem. XDA-Developers also spotted some leaked code that mentions the divot on the rear of the device may activate its voice assistant when you tap your finger to it. They also suggest it runs Android and packs a Qualcomm Snapdragon 730 processor.

Intel Kills Kaby Lake G, Vows To Offer Drivers For Five Years
by Peter Reutemann 09 Oct '19

09 Oct '19

'When Kaby Lake G debuted at CES 2018, it made a big bang. No one expected sworn rivals Intel and AMD to collaborate on a CPU package, marrying a 7th-gen Kaby Lake CPU with a unique AMD Radeon RX Vega GPU. But what began with a bang ended Monday with an unceremonious memo. >From a report: The Product Change Notification published by Intel on Monday confirmed that pretty much every single Kaby Lake G, including the Core i7-8706G, the Core i7-8705G, and the Core i5-8305G, would be discontinued. Last call for orders will be on January 17, 2020, and the final shipments are scheduled for July 31, 2020. While the end of life of a processor isn't typically a big deal to consumers who own them, one sticking point could have been driver support. Specifically, Kaby Lake G drivers for the custom AMD Radeon RX Vega M graphics come only from Intel. With a normal discrete GPU, the consumer would download drivers from the original company, such as Nvidia or AMD. With Kaby Lake G kaput, where does that leave Kaby Lake G-owners? Intel said the company will follow its standard policy and provide driver support for Kaby Lake G for five years from the launch of the product. All told, that probably means another 3.5 years of driver updates.' -- source: https://slashdot.org/story/19/10/09/142229 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/

Fedora Drops 32-Bit Linux
by Peter Reutemann 09 Oct '19

'Brian Fagioli, writing for BetaNews: Beginning with the upcoming version 31 of the operating system, i686 32-bit processor support is being dropped by the Fedora Project. "The i686 architecture essentially entered community support with the Fedora 27 release. Unfortunately, there are not enough members of the community willing to do the work to maintain the architecture. Don't worry, though -- Fedora is not dropping all 32-bit packages. Many i686 packages are still being built to ensure things like multilib, wine, and Steam will continue to work," says Justin Forbes of Fedora Project. Forbes further explains, "While the repositories are no longer being composed and mirrored out, there is a koji i686 repository which works with mock for building 32-bit packages, and in a pinch to install 32-bit versions which are not part of the x86_64 multilib repository. Of course, maintainers expect this will see limited use. Users who simply need to run a 32-bit application should be able to do so with multilib on a 64-bit system."' -- source: https://tech.slashdot.org/story/19/10/09/154256 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/

Internal Email Shows GitHub Plans To Renew ICE Contract
by Peter Reutemann 09 Oct '19

09 Oct '19

'GitHub CEO Nat Friedman explained why the company plans to renew a contract with U.S. Immigration and Customs Enforcement (ICE), even though he and others at GitHub oppose ICE's policy of separating children from parents at the border, Motherboard reported on Wednesday, citing an internal GitHub email. From a report: The email shows the continuing debate within the tech industry about whether companies should work specifically with ICE, and comes as a host of other companies have dealt with employee protests over corporate involvement with ICE. "In August, the GitHub leadership team learned about a pending renewal of our product by the U.S. Immigration & Customs Enforcement (ICE) agency. Since then, we have been talking with people throughout the company, based on our own personal concerns and those raised by Hubbers," Friedman's email reads, referring to GitHub employees. Evan Greer, deputy director at activism group Fight for the Future tweeted a copy of the email on Tuesday. Motherboard also separately obtained a copy of the email from a source inside GitHub. The product up for renewal is a license of GitHub Enterprise Server, an on-premises deployment of GitHub that customers can run on their own server, according to the email. ICE originally bought a license in April, 2016.' -- source: https://developers.slashdot.org/story/19/10/09/1557245 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/

Twitter transgression proves why its flawed 2FA system is such a privacy trap

'If ever there was a surefire way to sour users against a two-factor authentication system that was already highly flawed, Twitter has found it. On Tuesday, the social media site said that it used phone numbers and email addresses provided for 2FA protection to tailor ads to users. Twitter requires users to provide a valid phone number to be eligible for 2FA protection. A working cell phone number is mandatory even when users' 2FA protection is based solely on security keys or authenticator apps, which don't rely on phone numbers to work.

'Collapse OS' Is An Open-Source Operating System For the Post-Apocalypse
by Peter Reutemann 09 Oct '19

09 Oct '19

'Collapse OS is a new open-source operating system built specifically for use during humanity's darkest days. According to its creator, software developer Virgil Dupras, Collapse OS is what the people of the future will need to reconfigure their scavenged iPhones. For now, though, he's hosting the project on GitHub and looking for contributors. Motherboard reports: According to the Collapse OS site, Dupras envisions a world where the global supply chain collapses by 2030. In this possible future -- kind of a medium-apocalypse -- populations won't be able to mass produce electronics anymore, but they'll still be an enormous source of political and social power. Anyone who can scavenge electronics and reprogram them will gain a huge advantage over those who don't. Dupras believes that the biggest problem for tech savvy post-apocalyptic people will be microcontrollers -- tiny computers embedded in circuit boards that control the functions of computer systems. Collapse OS will work with Z80 8-bit microprocessors. Though less common today than 16- and 32-bit components, the 8-bit Z80 can be found in desktop computers, cash registers, musical instruments, graphing calculators, and everything in between. In a Reddit Q&A, Dupras explained that the Z80 was chosen "because it's been in production for so long and because it's been used in so many machines, scavenger have good chances of getting their hands on it." According to the product page, Collapse OS currently can run on a homebrew Z80-based computer called the RC2014, and on Reddit Dupras said it could theoretically run on a Sega Genesis console.' -- source: https://news.slashdot.org/story/19/10/08/2036204 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/

You Can Now Overclock a Raspberry Pi 4 For Some Nice Performance Gains
by Peter Reutemann 08 Oct '19

'The Raspberry Pi 4 is one of the cheapest single-board computers around. The new 4th generation is a solid performance lift over its predecessor and good bang for the buck if you're interested in learning Linux, working with embedded computing, or just want to kick back and play some retro games on an emulator. In addition, the latest version of the Raspberry Pi Foundation's Linux distribution, Raspbian Buster, comes with a new firmware revision for the tiny DIY PC that removes its 2GHz clock speed limit and allows voltage adjustments to wring out additional performance, with proper cooling of course. In testing, while there are no guarantees in overclocking, HotHardware was able to realize more than a 40% lift in their Raspberry Pi 4's processor clock speed, and a 50% boost to the GPU with an air-cooled mini case kit. Combined, they're not enough to turn the Pi 4 into your every day PC, but the performance gains are measurable and valuable. All it takes is a quick firmware update and a couple of Linux commands to dial things in.' -- source: https://hardware.slashdot.org/story/19/10/08/0312213 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/

'D-Link won't patch a critical unauthenticated command-injection vulnerability in its routers that could allow an attacker to remotely take over the devices and execute code. Threatpost reports: The vulnerability (CVE-2019-16920) exists in the latest firmware for the DIR-655, DIR-866L, DIR-652 and DHP-1565 products, which are Wi-Fi routers for the home market. D-Link last week told Fortinet's FortiGuard Labs, which first discovered the issue in September, that all four of them are end-of-life and no longer sold or supported by the vendor (however, the models are still available as new via third-party sellers). The root cause of the vulnerability, according to Fortinet, is a lack of a sanity check for arbitrary commands that are executed by the native command-execution function. Fortinet describes this as a "typical security pitfall suffered by many firmware manufacturers." With no patch available, affected users should upgrade their devices as soon as possible.

Attackers exploit 0-day vulnerability that gives full control of Android phones

'Attackers are exploiting a zero-day vulnerability in Google’s Android mobile operating system that can give them full control of at least 18 different phone models, including four different Pixel models, a member of Google’s Project Zero research group said on Thursday night. There’s evidence the vulnerability is being actively exploited, either by exploit developer NSO Group or one of its customers, Project Zero member Maddie Stone said in a post. NSO representatives, meanwhile, said the "exploit has nothing to do with NSO." Exploits require little or no customization to fully root vulnerable phones. The vulnerability can be exploited two ways: (1) when a target installs an untrusted app or (2) for online attacks, by combining the exploit with a second exploit targeting a vulnerability in code the Chrome browser uses to render content. “The bug is a local privilege escalation vulnerability that allows for a full compromise of a vulnerable device,” Stone wrote. “If the exploit is delivered via the Web, it only needs to be paired with a renderer exploit, as this vulnerability is accessible through the sandbox.”' -- source: https://arstechnica.com/information-technology/2019/10/attackers-exploit-0d… 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 Malware 'Patches' Chrome and Firefox To Fingerprint TLS Traffic
by Peter Reutemann 06 Oct '19

06 Oct '19

'A Russian cyber-espionage hacker group has been spotted using a novel technique that involves patching locally installed browsers like Chrome and Firefox in order to modify the browsers' internal components. The end goal of these modifications is to alter the way the two browsers set up HTTPS connections, and add a per-victim fingerprint for the TLS-encrypted web traffic that originates from the infected computers... According to a Kaspersky report published this week, hackers are infecting victims with a remote access trojan named Reductor, through which they are modifying the two browsers. This process involves two steps. They first install their own digital certificates to each infected host. This would allow hackers to intercept any TLS traffic originating from the host. Second, they modify the Chrome and Firefox installation to patch their pseudo-random number generation (PRNG) functions. These functions are used when generating random numbers needed for the process of negotiating and establishing new TLS handshakes for HTTPS connections. Turla hackers are using these tainted PRNG functions to add a small fingerprint at the start of every new TLS connection. The attack is being attributed to Turla, "a well-known hacker group believed to operate under the protection of the Russian government," ZDNet reports. And though the remote-access trojan already grants full control over a victim's device, one theory is the modified browsers offer "a secondary surveillance mechanism" if that trojan was discovered and removed. Researchers believe the malware is installed during file transfers over HTTP connections, suggesting an ISP had been compromised, according to the article. "A January 2018 report from fellow cyber-security firm ESET revealed that Turla had compromised at least four ISPs before, in Eastern Europe and the former Soviet space, also with the purpose of tainting downloads and adding malware to legitimate fil' -- source: https://news.slashdot.org/story/19/10/06/2242221 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/

To Fight Spectre-Like Attacks, Intel Suggests a New Kind of Memory
by Peter Reutemann 06 Oct '19

06 Oct '19

'Intel researchers published a paper last week suggesting a new kind of CPU memory to block side-channel attacks like Meltdown and Spectre, according to ZDNet: SAPM -- or Speculative-Access Protected Memory -- is the work of Intel STORM (STrategic Offensive Research & Mitigations), a team of elite security researchers that Intel assembled since 2017 to work on creating mitigations for all the speculative-execution attacks that have impacted the CPU maker's products. SAPM is only an idea for the moment, and there are no silicon prototypes. Intel STORM engineers only released "the theory and possible implementation options," to provide "a ground base for other researchers to improve upon and also for the industry to consider...." Intel STORM researchers say SAPM will implement protections at the hardware level and will work with both physical and virtual memory addresses. "SAPM can be applied to specific memory ranges, with the attribute that any memory access to such memory type will be instruction-level serialized, meaning that any speculative execution beyond the SAPM-accessing instruction will be stopped pending the successful retirement of this SAPM-accessing instruction," Intel STORM developers said in their short description of SAPM's basic principles... Intel STORM researchers say the second part (backend) of most speculative execution attacks performs the same actions. SAPM was designed to introduce hardware-based protections against the backend part of most attacks. It's because of this concept that Intel's research team believes that SAPM will also future-proof the next generations of Intel CPUs against other -- currently undiscovered -- speculative execution attacks. "Intel STORM researchers don't deny that there's a performance hit," the article adds. "However, this impact is low and could be mitigated further by dropping other existing protections."' -- source: https://hardware.slashdot.org/story/19/10/05/0315201 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/

COSMO and Psions
by tom butz 06 Oct '19

06 Oct '19

The Psions were good as long as there was still a dial-up Internet around: they could even generate the DTMF-tones out of telephone-numbers and use them to dial using your phone's microphone. I've kept a 3c-model because of its database program. None of the Psions actually were phones. As they only supported dial-up Internet, I had a look for ISP's that still supported that, and found one (serving the Australian Outback). Unfortunately they didn't accept new customers. As far as second screens are concerned, a while ago there was a Finnish/Russian phone/PDA that had a black and white additional screen on its back. That one drew very little power and could be used for notes and - checking who called. Typing, however, was as clumsy as on any phone. The COSMO features a colour-screen on its back - coloured LEDs instead obviously would've been as user-friendly as Morse-code (for telling you who was calling, if you didn't want to open your phone). In a perfect world, developers would have come up with a Psion keyboard, Internet/WiFi/Bluetooth capability and a black and white screen at the back. Today's cameras are good at taking/watching photos/videos, and they are a lot less chunky.

Psion Reborn
by Lawrence D'Oliveiro 05 Oct '19

The Cosmo Communicator should be shipping to its backers next week <https://www.theregister.co.uk/2019/10/04/planet_launches_cosmo_communicator…>. It has more than a passing resemblance to the Psion clamshell pocket PCs of the 1990s, except this one has an open design, intended to allow it to run a choice of open-source operating systems. This looks to be a niche market, compared to the millions of units shipped by all the usual big-name vendors. But if they can make enough money--and keep enough customers happy--to stay in business, why not?

Attorney General Bill Barr Will Ask Zuckerberg To Halt Plans For End-To-End Encryption Across Facebook's Apps
by Peter Reutemann 03 Oct '19

03 Oct '19

'Attorney General Bill Barr, along with officials from the United Kingdom and Australia, is set to publish an open letter to Facebook CEO Mark Zuckerberg asking the company to delay plans for end-to-end encryption across its messaging services until it can guarantee the added privacy does not reduce public safety. From a report: A draft of the letter, dated Oct. 4, is set to be released alongside the announcement of a new data-sharing agreement between law enforcement in the US and the UK; it was obtained by BuzzFeed News ahead of its publication. Signed by Barr, UK Home Secretary Priti Patel, acting US Homeland Security Secretary Kevin McAleenan, and Australian Minister for Home Affairs Peter Dutton, the letter raises concerns that Facebook's plan to build end-to-end encryption into its messaging apps will prevent law enforcement agencies from finding illegal activity conducted through Facebook, including child sexual exploitation, terrorism, and election meddling. "Security enhancements to the virtual world should not make us more vulnerable in the physical world," the letter reads. "Companies should not deliberately design their systems to preclude any form of access to content, even for preventing or investigating the most serious crimes." The letter calls on Facebook to prioritize public safety in designing its encryption by enabling law enforcement to gain access to illegal content in a manageable format and by consulting with governments ahead of time to ensure the changes will allow this access. While the letter acknowledges that Facebook, which owns Facebook Messenger, WhatsApp, and Instagram, captures 99% of child exploitation and terrorism-related content through its own systems, it also notes that "mere numbers cannot capture the significance of the harm to children."' -- source: https://it.slashdot.org/story/19/10/03/1847213 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/
