GoKawiilMagnet Forensics says GrayKey can defeat iPhone's Inactivity Reboot feature
404 Media reports that Magnet Forensics, maker of the GrayKey phone-unlocking tool, has found a way around iOS's Inactivity Reboot, which forces a locked iPhone to reboot after 72 hours of non-use. The report cites a law enforcement training video describing a new device called GrayKey Preserve and an Evidence Preservation Mode for existing GrayKey hardware, both reportedly built to keep a seized iPhone from returning to its more secure locked state.
GoKawiil's interpretation of the reporting above, not reported fact.
Inactivity Reboot was designed to blunt forensic access by forcing a locked phone back into its hardest-to-crack state before investigators can act, so a reported bypass could restore law enforcement's ability to pull data from seized devices within that window. It also raises the possibility, though unconfirmed, that similar techniques could be exploited beyond law enforcement if the method spreads, renewing the long-running contest between Apple's security updates and forensic tool makers.
- Magnet Forensics reportedly bypassed Apple's 72-hour Inactivity Reboot security feature.
- The bypass reportedly involves a new GrayKey Preserve device and an Evidence Preservation Mode.
- The report is based on a law enforcement training video reportedly dated early 2025.
