‘Sinkclose’ Flaw in Hundreds of Millions of AMD Chips Allows Deep, Virtually Unfixable Infections

  the most relevant:

  To take advantage of the vulnerability, a hacker has to already possess access to a computer’s kernel, the core of its operating system.

  For systems with certain faulty configurations in how a computer maker implemented AMD’s security feature known as Platform Secure Boot—which the researchers warn encompasses the large majority of the systems they tested—a malware infection installed via Sinkclose could be harder yet to detect or remediate, they say, surviving even a reinstallation of the operating system.

  For users seeking to protect themselves, Nissim and Okupski say that for Windows machines—likely the vast majority of affected systems—they expect patches for Sinkclose to be integrated into updates shared by computer makers with Microsoft, who will roll them into future operating system updates.

    So just another layer of suck on a completely compromised machine, I guess.

    It sounds like there’s no way to patch it once it’s been used, though, so for now it’s open season.
