Security research firm Calif says it used Mythos to help build a macOS kernel memory corruption exploit circumventing Apple's Memory Integrity Enforcement tech (Robert McMillan/Wall Street Journal)

A security research firm successfully demonstrated a macOS kernel exploit that bypasses Apple's Memory Integrity Enforcement, a critical security mechanism, raising concerns about the vulnerability of enterprise endpoints even on heavily protected systems. This breach of Apple's advanced security controls signals that sophisticated threat actors may now have viable attack vectors against macOS infrastructure, potentially impacting organizations relying on Apple devices for sensitive operations. IT leaders must reassess macOS security posture and patch management strategies, as traditional endpoint protection assumptions may no longer hold against advanced kernel-level exploits.
