Law enforcement officers are warning other officials and forensic experts that iPhones which have been stored securely for forensic examination are somehow rebooting themselves, returning the devices to a state that makes them much harder to unlock, according to a law enforcement document obtained by 404 Media.
The exact reason for the reboots is unclear, but the document authors, who appear to be law enforcement officials in Detroit, Michigan, hypothesize that Apple may have introduced a new security feature in iOS 18 that tells nearby iPhones to reboot if they have been disconnected from a cellular network for some time. After being rebooted, iPhones are generally more secure against tools that aim to crack the password of and take data from the phone.
“The purpose of this notice is to spread awareness of a situation involving iPhones, which is causing iPhone devices to reboot in a short amount of time (observations are possibly within 24 hours) when removed from a cellular network,” the document reads.
