I wouldn't bet on that lasting, though. This CCC someone essentially reverse-engineered microcode on 5-10 year old amd processors. I wouldn't be surprised if they figured out how to do it on newer processors and intel processors.
- userbinator 9y agoIntel's microcode updates are signed by a 2048-bit RSA key and some unknown 160-bit hash function (might be SHA-1, but none one publicly knows) for older models, with newer ones using a 256-bit hash function. Unless there's a very clever exploit, I doubt third-party microcode updates will ever be possible: http://inertiawar.com/microcode/ http://inertiawar.com/microcode/
