People who are troubled by security issues in Intel's Management Engine may also be suspicious of the firmware in AMD's roughly equivalent Platform Security Processor, which doesn't have a spotless record either. See, e.g., https://www.theregister.co.uk/2018/01/06/amd_cpu_psp_flaw/ https://www.theregister.co.uk/2018/01/06/amd_cpu_psp_flaw/
- coder543 7y agoI think we were talking about Spectre, Meltdown, and related attacks. Not the PSP or IME, although those are concerning too.
- floatboth 7y agoWell, Spectre affected pretty much all processors except very slow ones (Cortex-A53) :)
- coder543 7y agoIt affected AMD's Zen architecture significantly less. A number of exploits that applied to Intel didn't apply at all to Zen, and the ones that did apply had less costly mitigations than Intel.
