Sausalito, Calif. – Aug. 17, 2024
At the DEF CON hacker conference in Las Vegas earlier this month, Enrique Nissim and Krzysztof Okupski, researchers from the security firm IOActive, presented a vulnerability in AMD chips they’re calling Sinkclose.
WIRED reports that the flaw would allow hackers to run their own code in one of the most privileged modes of an AMD processor, known as System Management Mode, designed to be reserved only for a specific, protected portion of its firmware. IOActive’s researchers warn that it affects virtually all AMD chips dating back to 2006, or possibly even earlier.
Cybercrime Magazine caught up with Nissim and Okupski at DEF CON to get a first-hand account of the story.
