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/

AMD Ryzen Pro 3000 series desktop CPUs will offer full RAM encryption
by Peter Reutemann 02 Oct '19

02 Oct '19

'Monday, AMD announced Ryzen Pro 3000 desktop CPUs would be available in Q4 2019. This of course raises the question, "What's a Ryzen Pro?" The business answer: Ryzen Pro 3000 is a line of CPUs specifically intended to power business-class desktop machines. The Pro line ranges from the humble dual-core Athlon Pro 300GE all the way through to Ryzen 9 Pro 3900, a 12-core/24-thread monster. The new parts will not be available for end-user retail purchase and are only available to OEMs seeking to build systems around them. From a more technical perspective, the answer is that the Ryzen Pro line includes AMD Memory Guard, a transparent system memory encryption feature that appears to be equivalent to the AMD SME (Secure Memory Encryption) in Epyc server CPUs. Although AMD's own press materials don't directly relate the two technologies, their description of Memory Guard—"a transparent memory encryption (OS and application independent DRAM encryption) providing a cryptographic AES encryption of system memory"—matches Epyc's SME exactly. AMD Memory Guard is not, unfortunately, available in standard Ryzen 3000 desktop CPUs. If you want to build your own Ryzen PC with full memory encryption from scratch, you're out of luck for now.' -- source: https://arstechnica.com/gadgets/2019/10/amd-ryzen-pro-3000-series-desktop-c… 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/

Most mobile browsers display the Web, that’s it—Vivaldi Mobile can change that
by Peter Reutemann 01 Oct '19

01 Oct '19

'Vivaldi—makers of the power user's favorite Web browser—has finally released a mobile version. Vivaldi for Android (sorry iOS users, it's Android-only for now) brings most of what's great about Vivaldi to your phone, and thanks to Vivaldi's sync service, you can even have all your desktop data on your mobile device. Web browsers are perhaps the most important piece of software we use in 2019. Our devices are often little more than small windows onto the Web, and the browser is what we use to see and explore what's in that window. For all its importance though, the modern browser, especially the mobile Web browser, offers precious little in the way of features. It displays the Web and... that's about it. Want to interact with what you see? You're mostly out of luck. Most people probably like their browser this way. Google, maker of the most widely used mobile browser, rarely does anything without extensive user testing. If Chrome is minimalist, it's safe to assume it's that way because Google has determined that's what its users want. And since most other browsers copy whatever Google Chrome does, most mobile Web browsers end up as minimalistic pieces of software. On the desktop, of course, there has long been an exception to the uniformly dumbed-down offerings of Chrome, Firefox, and Safari—Vivaldi. Led by CEO Jon S. von Tetzchner, co-founder and former CEO of Opera, Vivaldi's primary goal is to build a useful browser, a tool you can bend to your will rather than the other way around. You can customize Vivaldi the way you like. Its preferences may be overwhelming at first glance, but if you dig in, you can make Vivaldi do just about whatever you want it to do. For this reason, Vivaldi is often called a "power user's browser" (as opposed to, I guess, the powerless user's browser). For all that, there was always one big problem with Vivaldi: it was desktop only. The company said it was working on a mobile version from the beginning, and von Tetzchner told me several times he was already using it. But there was nothing for the rest of us. Now Vivaldi Mobile is here (again, for Android users at least). Technically, it's a beta release and all the common cautions regarding beta software apply, but I've been using it for over a month now and have had no problems. Or, I should say, I have had problems, but updates prior to the public release eliminated all of them. And even if there were still bugs, Vivaldi would still be more useful than any other browser on my phone based on this recent testing—and yes, I've tried nearly all of today's mobile browsers, even the small, cottage efforts.' -- source: https://arstechnica.com/information-technology/2019/10/vivaldi-mobile-revie… 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 DNS-Over-TLS Plans Scrutinized By US Congress
by Peter Reutemann 30 Sep '19

30 Sep '19

'Google's plans to implement DNS over TLS in Chrome are being investigated by a committee in the U.S. House of Representatives, while the Justice Department has "recently received complaints" about the practice, according to the Wall Street Journal. An anonymous reader quotes Engadget: While Google says it's pushing for adoption of the technology to prevent spying and spoofing, House investigators are worried this would give the internet giant an unfair advantage by denying access to users' data. The House sent a letter on September 13th asking if Google would use data handled through the process for commercial purposes... Internet service providers are worried that they may be shut out of the data and won't know as much about their customers' traffic patterns. This could "foreclose competition in advertising and other industries," an alliance of ISPs told Congress in a September 19th letter... Mozilla also wants to use the format to secure DNS in Firefox, and the company's Marshall Erwin told the WSJ that the antitrust gripes are "fundamentally misleading." ISPs are trying to undermine the standard simply because they want continued access to users' data, Erwin said. Unencrypted DNS helps them target ads by tracking your web habits, and it's harder to thwart DNS tracking than cookies and other typical approaches.

Linus Torvalds Approves New Kernel 'Lockdown' Feature
by Peter Reutemann 29 Sep '19

29 Sep '19

'"After years of countless reviews, discussions, and code rewrites, Linus Torvalds approved on Saturday a new security feature for the Linux kernel, named 'lockdown'," reports ZDNet: The new feature will ship as a LSM (Linux Security Module) in the soon-to-be-released Linux kernel 5.4 branch, where it will be turned off by default; usage being optional due to the risk of breaking existing systems. The new feature's primary function will be to strengthen the divide between userland processes and kernel code by preventing even the root account from interacting with kernel code -- something that it's been able to do, by design, until now. When enabled, the new "lockdown" feature will restrict some kernel functionality, even for the root user, making it harder for compromised root accounts to compromise the rest of the OS... "When enabled, various pieces of kernel functionality are restricted," said Linus Torvalds, Linux kernel creator, and the one who put the final stamp of approval on the module yesterday. This includes restricting access to kernel features that may allow arbitrary code execution via code supplied by userland processes; blocking processes from writing or reading /dev/mem and /dev/kmem memory; block access to opening /dev/port to prevent raw port access; enforcing kernel module signatures; and many more others, detailed here.' -- source: https://linux.slashdot.org/story/19/09/30/0312211 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 Promises UK Government DNS-Over-HTTPS Won't Be Default in UK
by Peter Reutemann 29 Sep '19

29 Sep '19

'"Despite looking to make DNS-over-HTTPS the default for its American users, Mozilla has assured culture secretary Nicky Morgan that this won't be the case in the UK," reports Gizmodo: DNS-over-HTTPS has been fairly controversial, with the Internet Services Providers Association nominating Mozilla for an 'Internet Villain' over the whole thing, saying it will "bypass UK filtering obligations and parental controls, undermining internet safety standards in the UK." In his letter to Morgan, Mozilla vice president of global policy, trust and security, Alan Davidson, stressed that the company "has no plans to turn on our DNS-over-HTTPS feature by default in the United Kingdom and will not do so without further engagement with public and private stakeholders". He did add that Mozilla does "strongly believe that DNS-over-HTTPS would offer real security benefits to UK citizens. The DNS is one of the oldest parts of the internet's architecture, and remains largely untouched by efforts to make the web more secure. "Because current DNS requests are unencrypted, the road that connects your citizens to their online destination is still open and used by bad actors looking to violate user privacy, attack communications, and spy on browsing activity. People's most personal information, such as their health-related data, can be tracked, collected, leaked and used against people's best interest. Your citizens deserve to be protected from that threat."' -- source: https://news.slashdot.org/story/19/09/29/0434233 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/

Do We Need To Rethink What Free Software Is?
by Peter Reutemann 29 Sep '19

29 Sep '19

'Matthew Garrett is a security developer at Google and a Linux contributor who in 2014 won the Free Software Foundation's annual "Advancement of Free Software" award. But now he's asking if we need to re-think what free software is: If users can pay Amazon to provide a hosted version of a piece of software, there's little incentive for them to pay the authors of that software. This has led to various projects adopting license terms such as the Commons Clause that effectively make it nonviable to provide such a service, forcing providers to pay for a commercial use license instead. In general the entities pushing for these licenses are VC backed companies who are themselves benefiting from free software written by volunteers that they give nothing back to, so I have very little sympathy. But it does raise a larger issue -- how do we ensure that production of free software isn't just a mechanism for the transformation of unpaid labour into corporate profit...? At the same time, people are spending more time considering some of the other ethical outcomes of free software. Copyleft ensures that you can share your code with your neighbour without your neighbour being able to deny the same freedom to others, but it does nothing to prevent your neighbour using your code to deny other fundamental, non-software, freedoms. As governments make more and more use of technology to perform acts of mass surveillance, detention, and even genocide, software authors may feel legitimately appalled at the idea that they are helping enable this by allowing their software to be used for any purpose. The JSON license includes a requirement that "The Software shall be used for Good, not Evil", but the lack of any meaningful clarity around what "Good" and "Evil" actually mean makes it hard to determine whether it achieved its aims. As stewards of the free software definition, the Free Software Foundation should be taking the lead in ensuring that these issues are discussed. The priority of the board right now should be to restructure itself to ensure that it can legitimately claim to represent the community and play the leadership role it's been failing to in recent years, otherwise the opportunity will be lost and much of the activist energy that underpins free software will be spent elsewhere. If free software is going to maintain relevance, it needs to continue to explain how it interacts with contemporary social issues. If any organisation is going to claim to lead the community, it needs to be doing that.' -- source: https://news.slashdot.org/story/19/09/28/1741229 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/

Purism's Librem 5 Phone Starts Shipping. It Can Run Linux Desktop Apps
by Peter Reutemann 29 Sep '19

29 Sep '19

'On Tuesday Purism announced their first Librem 5 smartphones were rolling off the assembly line and heading to customers. "Seeing the amazing effort of the Purism team, and holding the first fully functioning Librem 5, has been the most inspirational moment of Purism's five year history," said their founder and CEO Todd Weaver. On Wednesday they posted a video announcing that the phones were now shipping, and Friday they posted a short walk-through video. "The crowdsourced $700 Linux phone is actually becoming a real product," reports Ars Technica: Purism's demand that everything be open means most of the major component manufacturers were out of the question. Perhaps because of the limited hardware options, the internal construction of the Librem 5 is absolutely wild. While smartphones today are mostly a single mainboard with every component integrated into it, the Librem 5 actually has a pair of M.2 slots that house full-size, off-the-shelf LTE and Wi-Fi cards for connectivity, just like what you would find in an old laptop. The M.2 sockets look massive on top of the tiny phone motherboard, but you could probably replace or upgrade the cards if you wanted... [Y]ou're not going to get cutting-edge hardware at a great price with the Librem 5. That's not the point, though. The point is that you are buying a Linux phone, with privacy and open source at the forefront of the design. There are hardware kill switches for the camera, microphone, WiFi/Bluetooth, and baseband on the side of the phone, ensuring none of the I/O turns on unless you want it to. The OS is the Free Software Foundation-endorsed PureOS, a Linux distribution that, in this case, has been reworked with a mobile UI. Purism says it will provide updates for the "lifetime" of the device, which would be a stark contrast to the two years of updates you get with an Android phone. PureOS is a Debian-based Linux distro, and on the Librem 5, you'll get to switch between mobile versions of the Gnome and KDE environments. If you're at all interested in PureOS, Purism's YouTube page is worth picking through. Dozens of short videos show that, yes, this phone really runs full desktop-class Linux. Those same videos show the dev kit running things like the APT package manager through a terminal, a desktop version of Solitaire, Emacs, the Gnome disk utility, DOSBox, Apache Web Server, and more. If it runs on your desktop Linux computer, it will probably run on the Librem 5, albeit with a possibly not-touch-friendly UI. The Librem 5 can even be hooked up to a monitor, keyboard, and mouse, and you can run all these Linux apps with the normal input tools... Selling a smartphone is a cutthroat business, and we've seen dozens of companies try and fail over the years. Purism didn't just survive long enough to ship a product -- it survived in what is probably the hardest way possible, by building a non-Android phone with demands that all the hardware components use open code. Making it this far is an amazing accomplishment.
