Physical access is one of the things that a trusted execution environment is supposed to protect against. It's one of the major reasons to use a TEE instead of just normal VM isolation.
- londons_explore 2y agoIf I were holding billions of dollars of bitcoin keys for a darknet drug market, I would not trust a TEE... A TEE restricts attackers to nation-state and similar actors today, and is probably no hurdle at all in 5-10 yrs when some attack like this is published and the hardware is unpatchable.
- hedora 2y agoAcademics break TEE’s on a regular cadence. There’s this article, for example. A while back, there was clkscrew. I don’t get the impression these classes of attacks will ever be patchable.
