AMD processors have a critical flaw in the firmware, called 'Sinkclose,' allowing hackers to run their code in the most privileged mode since at least 2006. This impacts nearly every AMD chip and poses a significant security threat.
While the AMD chip vulnerability has existed for years, it primarily affects systems where attackers already have deep access. Regular home PC users are unlikely to be impacted, but it poses a substantial threat to large entities like corporations and governments.
The severity of the AMD processor vulnerability lies in the potential for malicious code to embed itself deeply within the firmware, surviving even a complete operating system reinstallation. Infected devices may need to be replaced due to this persistent threat.
'Imagine nation-state hackers or whoever wants to persist on your system. Even if you wipe your drive clean, it's still going to be there,' says Krzysztof Okupski from IOActive, emphasizing the difficulty in completely eradicating the deep-rooted malware.
