GrayKey Freezes iPhones to Defeat Apple's Anti-Forensics Reboot
Cops Can Bypass iPhone's Automatic Reboot to Get into Locked Phones
Magnet Forensics, maker of the GrayKey phone-unlocking tool, has developed GrayKey Preserve and Evidence Preservation Mode to bypass the iPhone's inactivity reboot, which normally locks out police after 72 hours. Leaked training video shows the tool forces Airplane Mode to cut off radios and keep the phone in an After First Unlock state, preserving sensitive data indefinitely. A security researcher calls it a game changer, and the ball is now in Apple's court.
That AFU state is captured. Even if that device does reboot for any number of reasons, memory maintenance or the power is lost or whatever, the AFU state is not lost. This is the true magic behind the GrayKey Preserve and the Evidence Preservation Mode function.
