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

An anonymous reader quotes a report from Wired: Security flaws in your computer's firmware, the deep-seated code that loads first when you turn the machine on and controls even how its operating system boots up, have long been a target for hackers looking for a stealthy foothold. At the Defcon hacker conference tomorrow, Enrique Nissim and Krzysztof Okupski, researchers from the security firm IOActive, plan to present a vulnerability in AMD chips they're calling Sinkclose. Nissim and Okupski note that exploiting the bug would require hackers to already have obtained relatively deep access to an AMD-based PC or server, but that the Sinkclose flaw would then allow them to plant their malicious code far deeper still.
