Apple iPhones stored for forensic examination are allegedly rebooting themselves, making it difficult for police to get the info they need, PCMag reported. The reports come from a document put together by Detroit Law enforcement officials and obtained by 404 Media.
After the mysterious reboots, the devices supposedly enter what is called the Before First Unlock (BFU) state. This makes cracking them to get data about criminal activity much harder.
The document seen by 404 Media theorized that the iPhones rebooted in “a short amount of time” when removed from a cellular network, potentially around 24 hours. According to the document, one of the iPhones was even in Airplane mode and one was inside what is called a Faraday box, a type of container that blocks electronic signals from reaching the iPhone, stopping them from accessing telecom coverage, as well as things like Bluetooth and Wi-Fi.
TechCrunch reported iPhones might be harder for police to unlock, thanks to a new reboot feature. New code introduced in the latest version of Apple’s mobile operating system could make it more difficult for both police and thieves to unlock phones.
404 Media reported Thursday that law enforcement officials were warning each other that phones being stored for forensic examination seems to be rebooting themselves — something that security experts confirmed in a follow-up story. After the reboot, it’s harder for those phones to be unlocked by password-cracking tools.
This reboot appears to be taking place after iPhones with iOS 18.1 have not been unlocked for a set period of time. According to Chris Wade, founder of mobile analysis Corellium, iPhones seem to reboot after their fourth day in a locked state.
Gizmodo reported: We seem to have gotten an answer to the mystery of why iPhones in the custody of law enforcement have been rebooting themselves, making it harder for cops to break them open. Security researchers have found that the latest version of iOS, version 18.1, includes a feature called “inactivity reboot” that restarts a device approximately four days after being in a locked state.
404 Media reported earlier that week that police officers in Detroit were freaking out because iPhones in their custody for examination were randomly rebooting, making it more difficult to crack them open and exfiltrate data that could be useful in investigations.
Law enforcement and forensic experts quickly make their way into group chats in order to warn others to get data off devices in their custody as quickly as possible before the reboot happens.
Apple is constantly implementing new security measures into its devices, and it’s not likely that the company was specifically targeting law enforcement with this security enhancement.
In my opinion, it sounds like iPhones are going to be much harder for law enforcement to crack open and collect data from.
