Apple’s M1, M2, and M3 processors and can be exploited by the attack method to extract sensitive information.
A team of researchers recently found a side-channel vulnerability in Apple’s custom SoC architecture that does not appear patchable and allows for the theft of encryption keys.
The research team, which hails from six different universities around the United States, published its findings and is calling it the GoFetch attack. This is a “microarchitectural side-channel attack that can extract secret keys from constant-time cryptographic implementations via data memory-dependent prefetchers (DMPs).
