@_markel___@twitter.com has just published results of his research with Maxim Goryachy and Dmitry Sklyarov where they found "found two undocumented x86 instructions in Intel CPUs which completely control microarchitectural state". Which basically means they can write anything to the CPU, modify microcode etc 🤷
@kravietz If chips are controllable behind the scenes, imagine if that control could come from anywhere. Almost all computers are connected now, wired or wireless.
Surely in the future there will be far more people isolating themselves from computer chips of any kind. That would include communications. We’re all going to be like Islamic terrorists who allow no electronics anywhere near them.
@OscillatingAgama Thank you. That’s a lot worse. People in general and other countries have had longer to exploit it than we thought.
@kravietz
They say it works only after red pill unlock, so it's interesting but not a security issue.
