https://peertube.eqver.se/videos/watch/1e4439bf-6974-47d9-a1c6-8d9a748c7c33 A DEF CON 30 talk about a novel hardware-software attack on Apple M1 processors. The researcher demonstrates how to bypass Pointer Authentication (PAC), a security feature designed to prevent memory exploitation. The PACMAN method leverages microarchitectural side channels and speculative execution to brute-force pointer authentication codes without causing system crashes. The talk includes a practical demonstration of the attack and explains why such vulnerabilities emerge at the intersection of hardware design and software security mechanisms.
