Researchers have discovered a massive security vulnerability inside Apple M1 , M2 , and M3 silicon. The vulnerability, dubbed 'GoFetch,' steals cryptographic information from the CPU cache enabling an attacking program to build a cryptographic key from stolen data, allowing the application to access sensitive encrypted data. Ars Technica first reported on the security flaw.
GoFetch takes advantage of an overlooked security exploit in Apple silicon surrounding its state-of-the-art data memory-dependent prefetcher (DMP)
