New GoFetch attack on Apple Silicon CPUs can steal crypto keys

March 22, 2024 at 11:07AM The “GoFetch” attack targets modern Apple M-series CPUs’ constant-time cryptographic implementations, allowing it to steal secret cryptographic keys from the CPU’s cache. The attack, developed by researchers in the U.S., cannot be fixed in affected CPUs. Mitigating it with software patches would reduce cryptographic performance. Apple owners should practice safe … Read more
