Intel Planning To End Legacy BIOS Support By 2020, Report Says
by Peter Reutemann 20 Nov '17

20 Nov '17

'Intel is planning to end "legacy BIOS" support in their new platforms by 2020 in requiring UEFI Class 3 or higher. Making rounds this weekend is a slide deck from the recent UEFI Plugfest. Brian Richardson of Intel talked about the "last mile" barriers to removing legacy BIOS support from systems. By 2020, they will be supporting no less than UEFI Class 3, which means only UEFI support and no more legacy BIOS or CSM compatibility support mode. But that's not going to force on UEFI Secure Boot unconditionally: Secure Boot enabled is considered UEFI Class 3+. Intel hasn't removed legacy BIOS / CSM support yet due to many customers' software packages still relying upon legacy BIOS, among other reasons. Removing the legacy BIOS support will mitigate some security risks, needs less validation by vendors, allows for supporting more modern technologies, etc.' -- source: https://tech.slashdot.org/story/17/11/20/1251249 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/

Another Tor Browser Feature Makes It Into Firefox: First-Party Isolation
by Peter Reutemann 20 Nov '17

20 Nov '17

'Unbeknown to most users, Mozilla added a privacy-enhancing feature to the Firefox browser over the summer that can help users block online advertisers from tracking them across the Internet. The feature is named First-Party Isolation (FPI) and was silently added to the Firefox browser in August, with the release of Firefox 55. FPI works by separating cookies on a per-domain basis. This is important because most online advertisers drop a cookie on the user's computer for each site the user visits and the advertisers loads an ad. With FPI enabled, the ad tracker won't be able to see all the cookies it dropped on that user's PC, but only the cookie created for the domain the user is currently viewing. This will force the ad tracker to create a new user profile for each site the user visits and the advertiser won't be able to aggregate these cookies and the user's browsing history into one big fat profile. This feature was first implemented in the Tor Browser, a privacy-focused fork of the Firefox browser managed by the Tor Project, where it is known as Cross-Origin Identifier Unlinkability. FPI was added to Firefox as part of the Tor Uplift project, an initiative to bolster the Firefox codebase with some of the Tor Browser's unique privacy-focused features. The feature is not enabled by default. Information on how to enable it is in the linked article.' -- source: https://news.slashdot.org/story/17/11/20/1713235 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/

Bluetooth Hack Affects 20 Million Amazon Echo, Google Home Devices
by Peter Reutemann 17 Nov '17

17 Nov '17

'In September, security researchers discovered eight vulnerabilities -- codenamed collectively as BlueBorne -- in the Bluetooth implementations used by over 5.3 billion devices. We have now learned that an estimated 20 million Amazon Echo and Google Home devices are also vulnerable to attacks leveraging the BlueBorne vulnerabilities. The Hacker News reports: Amazon Echo is affected by the following two vulnerabilities: a remote code execution vulnerability in the Linux kernel (CVE-2017-1000251); and an information disclosure flaw in the SDP server (CVE-2017-1000250). Since different Echo's variants use different operating systems, other Echo devices are affected by either the vulnerabilities found in Linux or Android. Whereas, Google Home devices are affected by one vulnerability: information disclosure vulnerability in Android's Bluetooth stack (CVE-2017-0785). This Android flaw can also be exploited to cause a denial-of-service (DoS) condition. Since Bluetooth cannot be disabled on either of the voice-activated personal assistants, attackers within the range of the affected device can easily launch an attack. The security firm [Armis, who disclosed the issue] notified both Amazon and Google about its findings, and both companies have released patches and issued automatic updates for the Amazon Echo and Google Home that fixes the BlueBorne attacks.

Apologies for straying off topic. I need to get an Android phone to replace an ancient Sony-E, but hanker somewhat for the days of removable batteries, and like a stylus. This points afaict to an older Samsung Note model but then comes the problem of obsolete versions of Android. Can anyone suggest what is the oldest Android that can still be used on the web of today? Or perhaps there is a current phone with removable battery? ~ Ian Y

A History Of The Amiga, Part 11
by Lawrence D'Oliveiro 14 Nov '17

14 Nov '17

<https://arstechnica.com/gaming/2017/11/a-history-of-the-amiga-part-11-betwe…>: Then came an announcement that caused an uproar in the Amiga community; some even saw it as a betrayal. Jim Collas’ team revealed that it was switching the OS kernel for Amiga OE from QNX to Linux. ... In retrospect, this was probably the correct choice. Linux, then and now, supported a much more diverse array of hardware and was already gaining significant momentum in the tech industry. But Amiga fans didn’t see it that way at the time. They saw Linux as bloated, clunky, and slow, the exact opposite of their beloved Amiga. QNX Neutrino was seen as fast, small, and elegant, and the community had rallied behind it. This takes place in 1999. I did spend some time with Amiga fans about a decade earlier. Being a Mac fan at the time, I saw it as a bad move to tie to OS architecture so closely to particular quirks of the hardware. And sure enough, that did cause compatibility problems for Amiga software on later hardware.

How to Install Firefox Quantum in Ubuntu Right Now
by Peter Reutemann 12 Nov '17

12 Nov '17

'The upcoming version of Mozilla’s web browser Firefox is called Quantum because it’s blazing fast. It has been coded in Rust instead of the usual C++ and it is the first web browser to utilize the power of a multi-core processor. There has been lots of buzz around Quantum release. It is touted as a game-changing release that will help Firefox gain its lost userbase to Google Chrome. Ideally, Firefox Quantum should be released this month. But since I wanted to test it, I thought of installing it before its official release.' -- source: https://itsfoss.com/firefox-quantum-ubuntu/ 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/

Private Browsing Google Trouble
by Lawrence D'Oliveiro 12 Nov '17

Just tried to open a few Private Browsing sessions to do searches in Google in Firefox. Previously this has worked fine. But currently the connections are taking forever to complete. Explicitly connecting to google.com (instead of typing directly in the search box) has the same problem. Doing one of the same searches in a non-private tab worked fine. To compare, I connected to bing.com in a private tab, and did another of the searches there. Again, it worked fine.

New To Me: Game Asset Rippers
by Lawrence D'Oliveiro 12 Nov '17

12 Nov '17

While browsing around DeviantArt (as you do), I discovered this group <https://xnalaramodelandtuts.deviantart.com/>. The name “XNALara” comes from an open-source Windows program that let you create your own scenes and poses with assets (characters, props, scenery) from the “Tomb Raider: Underworld” game. (I think it has broadened its reach beyond that one game by now.) All very well, but how do you extract those assets from these games? Turns out there are these tools called “rippers”, which capture the OpenGL/DirectX drawing calls that the game makes and save all the geometry and textures and so on that are passed to those calls. (Did somebody say “copyright violation”?) Well, there are folders in that group that are absolutely full of these extracted assets. Some have been taken down on demand from the copyright owners, but the remarkable thing is that most of them are still available, and have been so for some years. And that the accounts of those uploading these collections have not been suspended. I tried loading one or two of them into Blender. There’s a range of formats, but one common combination is .obj+.mtl for the geometry and material definitions, and .dds for the texture images. The latter can be converted to PNG with ImageMagick and, after making corresponding edits to the references in the .mtl file, I was able to import the results and see something resembling the preview images. There have been artists on DeviantArt who have used these in their renders (and mentioned as much--that’s how I found out about them). I may try messing around with them a bit more, but I don’t think I’ll be publishing any such work...

3D Metal Printing At 100 Times The Speed And A Twentieth Of The Cost
by Lawrence D'Oliveiro 10 Nov '17

10 Nov '17

3D printing has mainly been confined to parts made out of various kinds of plastics up till now. Metal has been hard to deal with, because at some point you have to melt it, and that requires temperatures higher than any printing-type device could cope with. Now a company called “Desktop Metal” <http://www.theregister.co.uk/2017/11/10/metal_3d_printing_at_desktop_metal/> has come up with a scheme involving binding layers of metal powder, laid down in the right shape, using a temporary compound which is then removed when the part is melted in a furnace so it becomes a proper solid piece. Obviously this has to be done without losing its shape. The process can also do clever things like make a hinge, where there is no metal between the parts, so once the binding compound is removed, you have two solid parts that can freely rotate without falling apart.

MINIX: Intel's Hidden In-chip Operating System
by Peter Reutemann 09 Nov '17

09 Nov '17

'Matthew Garrett, the well-known Linux and security developer who works for Google, explained recently that, "Intel chipsets for some years have included a Management Engine [ME], a small microprocessor that runs independently of the main CPU and operating system. Various pieces of software run on the ME, ranging from code to handle media DRM to an implementation of a TPM. AMT [Active Management Technology] is another piece of software running on the ME." [...] At a presentation at Embedded Linux Conference Europe, Ronald Minnich, a Google software engineer reported that systems using Intel chips that have AMT, are running MINIX. So, what's it doing in Intel chips? A lot. These processors are running a closed-source variation of the open-source MINIX 3. We don't know exactly what version or how it's been modified since we don't have the source code. In addition, thanks to Minnich and his fellow researchers' work, MINIX is running on three separate x86 cores on modern chips. There, it's running: TCP/IP networking stacks (4 and 6), file systems, drivers (disk, net, USB, mouse), web servers. MINIX also has access to your passwords. It can also reimage your computer's firmware even if it's powered off. Let me repeat that. If your computer is "off" but still plugged in, MINIX can still potentially change your computer's fundamental settings. And, for even more fun, it "can implement self-modifying code that can persist across power cycles." So, if an exploit happens here, even if you unplug your server in one last desperate attempt to save it, the attack will still be there waiting for you when you plug it back in. How? MINIX can do all this because it runs at a fundamentally lower level. [...] According to Minnich, "there are big giant holes that people can drive exploits through." He continued, "Are you scared yet? If you're not scared yet, maybe I didn't explain it very well, because I sure am scared." Also read: Andrew S. Tanenbaum's (a professor of Computer Science at Vrije Universiteit) open letter to Intel' -- source: https://tech.slashdot.org/story/17/11/07/1041236 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/
