GrayKey reportedly bypasses iOS Inactivity Reboot protection

Magnet Forensics, maker of the GrayKey iPhone-cracking device, has developed a workaround for Apple's Inactivity Reboot feature, which restarts an iPhone after 72 hours without unlocking. The new GrayKey Preserve device keeps the phone in the less secure After First Unlock state and recovers data iOS normally purges.

• Inactivity Reboot restarts an iPhone after 72 hours without unlocking
• GrayKey Preserve keeps the device in After First Unlock mode even after a restart
• The exploit has reportedly been used since at least early 2025
• Recovered data includes location data, iMessages and deleted images
