>and wait
Oh you'll definitely have to wait.

This is a week old and I can't believe none of you other dorks mentioned this.

>But the Plundervolt researchers found out that ‘undervolting’ CPUs by just the right amount could indeed put the CPU into a sort of digital twilight zone where it would keep on running yet start to make subtle mistakes.
>The code thought it was skipping to data a safe distance ahead in memory, e.g. 17 million bytes forward; but the undervolted multiplication tricked the CPU into reading memory from an unsafe distance backwards in memory, outside the memory region assigned to the enclave, e.g. 519 million bytes backward.

For brainlets:
>be LINK node operator
>so and so (probably corporate) wants confidentiality using TEEs for sensitive and highly valuable data
>you say okay (but you're a bad actor)
>starve the node's CPU of a little voltage
>fetch data from inside the enclave to outside it
>sell it on the black market and do whatever else bad actors do with confidential data

At least there's still mixicles or this project would be completely dead and worthless.

What this means (for brainlets):
>4th Industrial Revolution delayed
>Another 2 years of bag-holding

Thanks intel for the christmas gift
