Apple Silicon Vulnerability Allows Hackers to Extract Encryption Keys
An unpatchable vulnerability has been discovered in Apple's M-series chips that allows attackers to extract secret encryption keys from Macs under certain conditions.
Named "GoFetch," the type of cyber attack described involves Data Memory-Dependent Prefetchers (DMPs), which try to predict what data the computer will need next and retrieve it in advance. This is meant to make processing faster, but it can unintentionally reveal information about what the computer is doing.
The paper finds that DMPs, especially the ones in Apple's processors, pose a significant threat to the security provided by constant-time programming models, which are used to write programs so that they take the same amount of time to run, no matter what data they're dealing with.
