Security: BGP Hijack Factory, IDN, Microsoft Windows Back Doors and Intel Defects

  • Shutting down the BGP Hijack Factory

    It started with a lengthy email to the NANOG mailing list on 25 June 2018: independent security researcher Ronald Guilmette detailed the suspicious routing activities of a company called Bitcanal, whom he referred to as a “Hijack Factory.” In his post, Ronald detailed some of the Portuguese company’s most recent BGP hijacks and asked the question: why Bitcanal’s transit providers continue to carry its BGP hijacked routes on to the global [I]nternet?

    This email kicked off a discussion that led to a concerted effort to kick this bad actor, who has hijacked with impunity for many years, off the [I]nternet.

  • Malformed Internationalized Domain Name (IDN) Leads to Discovery of Vulnerability in IDN Libraries

    The Punycode decoder is an implementation of the algorithm described in section 6.2 of RFC 3492. As it walks the input string, the Punycode decoder fills the output array with decoded code point values. The output array itself is typed to hold unsigned 32-bit integers while the Unicode code point space fits within 21 bits. This leaves a remainder of 11 unused bits that can result in the production of invalid Unicode code points if accidentally set. The vulnerability is enabled by the lack of a sanity check to ensure decoded code points are less than the Unicode code point maximum of 0x10FFFF. As such, for offending input, unchecked decoded values are copied directly to the output array and returned to the caller.

  • GandCrab ransomware adds NSA tools for faster spreading

    "It no longer needs a C2 server (it can operate in airgapped environments, for example) and it now spreads via an SMB exploit -- including on XP and Windows Server 2003 (along with modern operating systems)," Beaumont wrote in a blog post. "As far as I'm aware, this is the first ransomware true worm which spreads to XP and 2003 -- you may remember much press coverage and speculation about WannaCry and XP, but the reality was the NSA SMB exploit (EternalBlue.exe) never worked against XP targets out of the box."

  • Intel Discloses New Spectre Flaws, Pays Researchers $100K

    Intel disclosed a series of vulnerabilities on July 10, including new variants of the Spectre vulnerability the company has been dealing with since January.

    Two new Spectre variants were discovered by security researchers Vladimir Kiriansky and Carl Waldspurger, who detailed their findings in a publicly released research paper tilted, "Speculative Buffer Overflows: Attacks and Defenses."

    "We introduce Spectre1.1, a new Spectre-v1 variant that leverages speculative stores to create speculative buffer over-flows," the researchers wrote. "We also present Spectre 1.2 on CPUs that do not enforce read/write protections, speculative stores can overwrite read-only data and code pointers to breach sandboxes."

Announcing CrossOver 18.5.0 and Games for GNU/Linux

  • Announcing CrossOver 18.5.0
    CrossOver 18.5 includes the FAudio library to provide superior audio support for games. FAudio is a reimplementation of XAudio2, a low-level audio library for Windows. This improvement broadens CrossOver’s game compatibility and resolves a wide variety of audio bugs on both macOS and Linux. CrossOver 18.5 resolves several Office 2010 bugs related to activation and licensing. The first involves a change which disrupted the activation status of Office 2010 bottles upgraded from CrossOver 17.x and earlier to CrossOver 18.x. Users who experienced persistent activation requests on earlier releases of CrossOver 18 should be able to successfully activate Office 2010 on CrossOver 18.5. We have also resolved a bug which caused Office 2010 to attempt and fail configuration on every launch for some users. On Linux, CrossOver 18.5 supports the very latest release of Office 365 and resolves a sign-in bug impacting Office 365 Home users. Finally, CrossOver 18.5 includes preliminary support for OneNote 2016 on Linux.
  • CrossOver 18.5 Released - Based On Wine 4.0 While Pulling In FAudio
    CodeWeavers, the main sponsor/contributor to the Wine project, announced the release today of their commercial CrossOver 18.5 software for more easily running Windows games and applications on Linux and macOS.
  • The GOG Spring Sale is now live, tons of titles discounted with flash deals each day
    Someone please lock away my wallet, as the GOG Spring Sale is live and it's full of discounted Linux games. For this huge sale, GOG are also doing Flash Deals so every 24 hours a couple of games will get a higher than usual discount so you will need to keep going back for the best.
  • Valve show off their new Steam Library design and a new Events page
    At GDC today, Valve did their presentation and they finally showed off the new design coming for the Library page and more. For those with a growing backlog of games, the Steam Library as it is right now is so basic it's just incredibly unhelpful. Going by what they've shown off, it's actually looking a serious amount better. Firstly, it has a home page for your Steam Library, to go over some recent games and recently updated titles, as well as show a slice of your friends list. That's a pretty handy feature, especially if you have a game you play regularly enough it will probably be quicker and easier to get going the next time.
  • You can now try XCOM 2 free until March 25th, also on a big sale
    Firaxis Games have put their strategy game XCOM 2 up to play for free between now and March 25th, so if you've been on the fence this is a great opportunity. It's quite easily my absolute favourite strategy game on Linux, much more interesting than the first of the newer XCOM games (although that's still damn fun too). It does have a few niggles and some performance issues here and there but that's not down to Feral Interactive's port as it's not much different on Windows.
  • Humble Store are giving away Tacoma during their Indie Mega Week sale
    Humble Store has another free game from you to grab with Tacoma, along with their Indie Mega Week sale now live. I enjoyed my Tacoma play-through, done in a single sitting and I think it's worth grabbing and actually playing. You can see my previous thoughts here. You can grab your free copy here, which requires subbing to their newsletter.
