for many modern desktops/laptops (including recent Apple machines, which i don't think was the case even just a few product cycles ago), Intel's vPro appears capable of many forms of surveillance/subversion.
in terms of understanding/mitigating these types of threats, i wish an open, crowdfunded project to reverse engineer the contents of intel's microcode updates existed to the point they were understandable by the tech press.
i also wish an easy-to-use package for blacklisting cpu-based and crypto-related kernel modules (like aes-ni) existed for a broad range of processors..
and of course only somewhat relatedly, i continue to wish the man page for random(4) would be rewritten in light of the risk of these types of backdoors.
- nezza-_- 12y agoto reverse engineer the contents of intel's microcode updates I don't think that's (sanely) possible. The amount of information needed about the silicon is very high and modern x86 processors are (for now) pretty much impossible to reverse engineer by delayering and taking pictures of the insides of the chip (14nm = ~60 atoms)... Also the costs of people who are able to reverse engineer such stuff would be very very high.
