I work with a bunch of hardware engineers who used to work at intel and the really knowledgeable ex-intel guy I know said speculative execution has always been known to be risky but actually exploiting it was presumed to be very difficult/impossible.
Looking back, I should have asked him how intel evaluates security risks considering how much of modern day computing uses it (which makes it an extremely valuable black hack exploit since it can work on practically every computer).
- mannykannot 9y agoIn practice, if you cannot demonstrate an exploit, your concerns will be heavily discounted, and this is a case in point. Even if you do show an exploit, attempts will often be made to dismiss it as infeasible in practice (this is for security issues in general, not specifically Intel.)
