Apple and Cyber Agencies Urge Immediate iPhone Updates and Manual Restarts

Overview

• Apple released fixes in iOS 26.2 for newer iPhones and iOS 18.7.3 for older models and urges users to update and restart without delay.
• France’s ANSSI and the U.S. NSA advise full power-offs and manual restarts, ideally weekly, to disrupt memory-resident spyware.
• ANSSI warns that some spyware can simulate a software reboot, so users should perform hardware-triggered shutdowns or force restarts.
• The current campaigns use zero-click WebKit exploits often delivered via stock messaging such as iMessage, leaving no reliable behavioral workaround.
• Manual restarts only clear non-persistent malware, while persistent implants require installing Apple’s security updates to be removed.
