Police Freak Out at iPhones Mysteriously Rebooting Themselves, Locking Cops Out (404media.co) 129

Posted by msmash from the stranger-things dept.
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, 404 Media is reporting, citing a law enforcement document it obtained. From the report: 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. Apple did not provide a response on whether it introduced such an update in time for publication.

    I recently got notifications on my Pixel about enabling theft protection features that lock the screen if there's a suspected snatch of the phone. Plus another setting that will lock the phone if it goes offline. Seems reasonable to me.

        I have a somewhat similar issue with my smart watch. It runs a backup to the phone, which then further backs that up into the cloud. The problem is, they designed it with "no one ever turns off their devices" in mind, so it will only run a backup in the middle of the night. Which is when both my phone and watch are shut off. There's no way to trigger the backup manually. So I either leave both on overnight once in a while, or live with "watch not backed up in over 7 days!" warnings. Sigh.

        With no connectivity? The timing would be unlikely, cops getting a phone after an update had been downloaded, but before it was installed. But it's not clear that even that is sufficient. Apple says "When an update is available, iPhone downloads and installs the update overnight while charging and connected to Wi-Fi. You're notified before an update is installed."

        I believe iOS tries to learn your activity schedule so will perform the reboot at your convenience - which can be immediately, 2AM or when it decides you're normally idle. And the 2AM ones you schedule require your password.

        It also has to be plugged in before it does the update - I've missed many 2AM reboots because it isn't plugged in at all.

      Always turn your phone off when going through customs or in any other scenario where it might be confiscated and searched.

      In the case of iPhone, this does the job without powering off: simply hold the volume-up and the right button simultaneously to get to the power-off/medical-id/SOS/911 screen. After that, the phone is locked (i.e., needing PIN to unlock). On iOS 18, swiping to the control panel screen and pressing the 0/1 power icon in the upper right corner also leaves the phone in a locked state.
