Key Developments & Data
Magnet Forensics reportedly developed a hardware solution called "GrayKey Preserve" to bypass the iOS 18.1 Inactivity Reboot feature.
The standard Apple $AAPL security feature forces an iPhone to reboot after 72 hours of inactivity, dropping it from a vulnerable After First Unlock (AFU) state to a highly encrypted Before First Unlock (BFU) state.
According to a leaked early 2025 tutorial video obtained by 404 Media, the new Evidence Preservation Mode captures and holds the AFU state even if the device loses power or attempts memory maintenance.
Security researcher Jiska Classen suspects the tool works by manipulating the internal iPhone clock or disabling the specific processes responsible for expiring the sensitive data.
The capability remains officially unconfirmed by Apple and Magnet Forensics, leaving it entirely unclear if the workaround functions on the most recent minor iOS updates.
"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." — Magnet Forensics employee

Zubiqo Strategic Assessment
Primary Impact
Law enforcement forensics units and digital privacy advocates face a renewed technical arms race over physical device extraction and data preservation timelines.
Strategic Shift
The transition from software-based encryption expiration timers to brute-force hardware-level state preservation tools in mobile forensics.
The Ripple Effect
Apple will likely deploy a silent background patch in an upcoming iOS minor update to harden the system clock and AFU expiration triggers against external hardware manipulation.
