Apple’s latest iPhone 17 and iPhone Air have introduced a new security feature called Memory Integrity Enforcement (MIE), designed to combat memory corruption vulnerabilities often exploited by spyware developers. MIE significantly enhances device security by raising the cost and complexity for spyware creators, potentially making iPhones some of the most secure devices available. Experts believe this feature will reduce the efficacy of both remote hacks and physical device attacks, although no system can be entirely foolproof. While MIE marks a significant advancement in cybersecurity, its overall impact will depend on third-party implementation and user adoption.
