  • Microsoft's compromised Secure Boot implementation

    There's been a bunch of coverage of this attack on Microsoft's Secure Boot implementation, a lot of which has been somewhat confused or misleading. Here's my understanding of the situation.

    Windows RT devices were shipped without the ability to disable Secure Boot. Secure Boot is the root of trust for Microsoft's User Mode Code Integrity (UMCI) feature, which is what restricts Windows RT devices to running applications signed by Microsoft. This restriction is somewhat inconvenient for developers, so Microsoft added support in the bootloader to disable UMCI. If you were a member of the appropriate developer program, you could give your device's unique ID to Microsoft and receive a signed blob that disabled image validation. The bootloader would execute a (Microsoft-signed) utility that verified that the blob was appropriately signed and matched the device in question, and would then insert it into an EFI Boot Services variable[1]. On reboot, the boot loader reads the blob from that variable and integrates that policy, telling later stages to disable code integrity validation.

  • FreeBSD devs ponder changes to security processes

    The developers of FreeBSD have announced they'll change the way they go about their business, after users queried why known vulnerabilities weren't being communicated to users.

    This story starts with an anonymous GitHub post detailing some vulnerabilities in the OS, specifically in freebsd-update, libarchive, bspatch and portsnap. Some of the problems in that post were verified and the FreeBSD devs started working on repairs.

  • 10 IoT Security Best Practices For IT Pros

    IT professionals have to treat internet of things (IoT) vulnerabilities as they would vulnerabilities in databases or web applications. Any flaw can bring unwelcome attention, for those making affected products and those using them. Any flaw may prove useful to compromise other systems on the network. When everything is connected, security is only as strong as the weakest node on the network.

  • Like The Rest Of The Internet Of Things, Most 'Smart' Locks Are Easily Hacked

    Smart refrigerators that leak your e-mail credentials. Smart TVs that collect but then fail to secure your living room conversations. Smart thermostats that can be loaded with ransomware. Smart vehicles that can be hacked and potentially kill you. This is the end result of "Internet of Things" evangelists and companies that for the last half-decade put hype and profit (the cart) well ahead of consumer privacy and security (the horse), in the process exposing us all to thousands of new attack vectors in homes and businesses around the world.

  • If census site was taken down after DDoS attack it wasn't prepared: expert

    The attack against the census website that resulted in it being taken down last night appears, at face value, to have been nothing more than the standard attack perpetrated against countless sites every day by everyone from children to malcontents with an axe to grind, an expert says.

    That the site was attacked is not in the least bit surprising, security adviser Troy Hunt told Fairfax Media, but it was unexpected that an attack of this kind would result in the site going down.

  • Census 2016: ABS needs to provide proof of DDoS

    Technical people like him are what we need to cut through all the bulldust. One person who is an expert in this art is Craig Sanders, a systems administrator of many decades, and one who can speak plainly. Many years ago, following a major distributed denial of service of attack on the Internet's root name servers, he was one who educated me on the phenomenon. This time was no different with Sanders; he calmly and clearly pointed me in the direction of the evidence that was needed.

    If the census website crashed due to foreign intervention — either through a denial of service or a distributed denial of service — how is it that none of the major security companies around the world did not notice it? You would need an attack of some magnitude to take down the ABS census site.

  • Researchers crack Microsoft feature, say encryption backdoors similarly crackable [Ed: by design]

    Researchers who uncovered a security key that protects Windows devices as they boot up say their discovery is proof that encryption backdoors do not work.

    The pair of researchers, credited by their hacker nicknames MY123 and Slipstream, found the cryptographic key protecting a feature called Secure Boot.

    They believe the discovery highlights a problem with requests law enforcement officials have made for technology companies to provide police with some form of access to otherwise virtually unbreakable encryption that might be used by criminals.

    “Microsoft implemented a ‘secure golden key’ system. And the golden keys got released from [Microsoft's] own stupidity,” wrote the researchers in their report, in a section addressed by name to the FBI.

    “Now, what happens if you tell everyone to make a ‘secure golden key’ system? Hopefully you can add 2+2.”

    Secure Boot is a built into the firmware of computer — software unique to different types of hardware that exists outside the operating system and is used to boot the OS.

  • Containerized Security: The Next Evolution of Virtualization?

    We in the security industry have gotten into a bad habit of focusing the majority of our attention and marketing dollars on raising awareness of the latest emerging threats and new technologies being developed to detect them. One just has to look at the headlines or spend fifteen minutes walking the show floor at a major security conference to see this trend. However, while we are focusing on what all the bad guys are doing, we’ve taken the eye off the ball of where our infrastructure business is going.

  • Bungling Microsoft singlehandedly proves that golden backdoor keys are a terrible idea [Ed: Microsoft and backdoor should become synonymous. At every level, online and offline, Microsoft products booby-trapped with backdoors.]

    Microsoft leaked the golden keys that unlock Windows-powered tablets, phones and other devices sealed by Secure Boot – and is now scrambling to undo the blunder.

    These skeleton keys can be used to install non-Redmond operating systems on locked-down computers. In other words, on devices that do not allow you to disable Secure Boot even if you have administrator rights – such as ARM-based Windows RT tablets – it is now possible to sidestep this block and run, say, GNU/Linux or Android.

    What's more, it is believed it will be impossible for Microsoft to fully revoke the leaked keys.

    And perhaps most importantly: it is a reminder that demands by politicians and crimefighters for special keys, which can be used by investigators to unlock devices in criminal cases, will inevitably jeopardize the security of everyone.

    Microsoft's misstep was uncovered by two researchers, MY123 and Slipstream, who documented their findings here in a demoscene-themed writeup published on Tuesday. Slip believes Microsoft will find it impossible to undo its leak.

  • Your 'Smart' Thermostat Is Now Vulnerable To Ransomware

    We've noted time and time again how the much ballyhooed "internet of things" is a privacy and security dumpster fire, and the check is about to come due. Countless companies and "IoT" evangelists jumped head first into the profit party, few bothering to cast even a worried look over at the reality that basic security and privacy standards hadn't come along for the ride. The result has been an endless parade of not-so-smart devices and appliances that are busy either leaking your personal details or potentially putting your life at risk.

    Of course, the Internet of Things hype machine began with smart thermostats and the sexy, Apple-esque advertising of Nest. The fun and games didn't last however, especially after several botched firmware updates resulted in people being unable to heat or cool their homes (relatively essential for a thermostat).

  • Report: Linux security must be upgraded to protect future tech
    The summit was used to expose a number of flaws in Linux's design that make it increasingly unsuitable to power modern devices. Linux is the operating system that runs most of the modern world. It is behind everything from web servers and supercomputers to mobile phones. Increasingly, it's also being used to run connected Internet of Things (IoT) devices, including products like cars and intelligent robots.
  • security things in Linux v4.6
    Hector Marco-Gisbert removed a long-standing limitation to mmap ASLR on 32-bit x86, where setting an unlimited stack (e.g. “ulimit -s unlimited“) would turn off mmap ASLR (which provided a way to bypass ASLR when executing setuid processes). Given that ASLR entropy can now be controlled directly (see the v4.5 post), and that the cases where this created an actual problem are very rare, means that if a system sees collisions between unlimited stack and mmap ASLR, they can just adjust the 32-bit ASLR entropy instead.
