Holy shit, Christopher Domas is back. I remember watching his Defcon talks on x86 shenanigans[^1][^2] and being amazed at what he's been able to discover. Then he got whisked away by Intel and now drops this. I'm excited. [^1]: ▶ this video [^2]: link
These links don't work for me, but the videos are on YT: - link - ▶ this video And yes, they are spectacular.
While somewhat interesting, I'm not sure there's much to discuss unless the presentation or details are already available. Interestingly, this reminds me of two Defcon talks I watched in the last day or two, which also cover vulnerability through additional processors onboard.[1][2] 1: link 2: ▶ this video
