Claude Mythos helped a four-person startup team at Caliph break Apple’s Memory Integrity Enforcement and gain full root access to an M5 Mac in just five days. The exploit targeted one of Apple’s most ambitious memory safety defenses, built over five years to harden consumer operating systems.
The breakthrough came from a human-AI workflow: Mythos rapidly identified known vulnerable bug patterns from prior research, while the researchers solved the novel bypass that the model had never seen before. That combination compressed what would normally take months of security work into less than a week.
Apple has already patched one issue in macOS 26.5 and, for the first time, credited an AI model in its security notes. The result signals a major shift for cybersecurity, where AI-assisted research is accelerating both offensive discovery and defensive response across the industry.
