AMD told MrBruh that all update communications now use HTTPS and that updates undergo signature verification. The researcher says he verified the HTTPS claim, but found only a CRC32 check on the downloaded executable, which is not considered a cryptographic signature.
This is the most shocking part. You’d think that AMD as a high-tech company has some smart people working for them. These are very basic things that any half decent programmers should get right. If at no part of the process of implementing this anyone brought up that this is not secure, that is extremely worrying and indicative of a very broken development process. It’s not like a proper cryptographic signature costs extra. This is just pure incompetence.
