A new side-channel attack called "GoFetch" impacts Apple M1, M2, and M3 processors and can be used to steal secret cryptographic keys from data in the CPU's cache.
The attack targets constant-time cryptographic implementations using data memory-dependent prefetchers (DMPs) found in modern Apple CPUs. This allows it to recreate the...
