Apple Quietly Introduced iPhone Reboot Code Which is Locking Out Cops (www.404media.co)

Apple quietly introduced code into iOS 18.1 which reboots the device if it has not been unlocked for a period of time, reverting it to a state which improves the security of iPhones overall and is making it harder for police to break into the devices, according to multiple iPhone security experts.

On Thursday, 404 Media reported that law enforcement officials were freaking out that iPhones which had been stored for examination were mysteriously rebooting themselves. At the time the cause was unclear, with the officials only able to speculate why they were being locked out of the devices. Now a day later, the potential reason why is coming into view.

“Apple indeed added a feature called ‘inactivity reboot’ in iOS 18.1.,” Dr.-Ing. Jiska Classen, a research group leader at the Hasso Plattner Institute, tweeted after 404 Media published on Thursday along with screenshots that they presented as the relevant pieces of code.

Law enforcement shouldn't be able to get into someone's mobile phone without a warrant anyway. All this change does is frustrate attempts by police to evade going through the proper legal procedures and abridging the rights of the accused.

well it's kind of a selling point. I'm just too used to using android, though.

Edit - there's something for that too, cool!

You can enable lockdown mode. It forces the next unlock to ignore biometrics and require a pin, which police cannot force you to divulge without a warrant. Once enabled, you get a "lockdown mode" option in the menu when you hold down your power button.

Although lockdown mode is a good step and helps defend against biometric warrents, it does not wipe the encryption keys from RAM. This can only be achieved by using a secondary (non-default) user profile on GrapheneOS, and triggering the End session feature. This fully removes the cryptographic secrets from memory, and requires the PIN or password to unlock, which is enforced through the StrongBox and Weaver API of the Titan M2 secure element in Pixel devices.
