- Apple announced Memory Integrity Enforcement (MIE) as part of their September event, a major security upgrade for iPhone 17 and iPhone Air.
- MIE provides always-on memory safety protection, stopping memory corruption attacks by tagging memory with secret codes and verifying access.
- The system prevents buffer overflows and use-after-free bugs, common attack vectors, by ensuring every memory location has a unique tag.
- Apple redesigned hardware and software together, dedicating silicon resources in A19 and A19 Pro chips to security without performance overhead.
- Developers can test MIE in Xcode, extending security benefits to third-party apps, which often face higher risks.
- Apple's offensive research team tested MIE against real-world exploits, finding it effectively blocks previously successful attack chains.
- MIE targets sophisticated threats like mercenary spyware, providing silent, always-on protection for users.
- The system redefines memory safety, disrupting exploitation techniques from the past 25 years and setting a new industry standard.
- Apple's approach demonstrates comprehensive security without sacrificing performance, likely influencing broader industry practices.
