Re: Downgrade attack?
@ stuff and nonesense
Exactly! But now you have AMD and Intel both saying they have this wonderful ME/PSP solution so that you don't have to do that kind of low level check any more. Then we find out their "solution" is completely broken, but now we can't even really get the golden hashes required to verify the firmware since UEFI only updates chunks of what's actually on that Flash device (or devices).
Bad situation all around, brought on by ever increasing DRM strategies and pure greed by Intel and AMD....
