New Plundervolt attack impacts Intel CPUs

Academics from three universities across Europe have disclosed today a new attack that impacts the integrity of data stored inside Intel SGX, a highly-secured area of Intel CPUs.

The attack, which researchers have named Plundervolt, exploits the interface through which an operating system can control an Intel processor’s voltage and frequency — the same interface that allows gamers to overclock their CPUs.

Academics say they discovered that by tinkering with the amount of voltage and frequency a CPU receives, they can alter bits inside SGX to cause errors that can be exploited at a later point after the data has left the security of the SGX enclave.
