For those who like myself don't know what PSP might be, from the article:<p>> In short, it’s a coprocessor that has access to just about every part of the computers to which it’s inside. This makes it a prime target for attacks. Introduced around 2013, it’s also entirely closed source, existing as an unknown black box within modern AMD CPUs, which makes the security-conscious highly wary. Operating at a low-level, entirely outside the purview of the main CPU and operating system, the PSP, like the IME, is often considered a potential backdoor into a machine.
