Apple’s brand-new apple iphone software application includes an unique safety and security function that restarts the phone if it’s not opened for 72 hours, according to safety and security scientists.
Last week, 404 Media reported that police policemans and forensic specialists were worried that some apples iphone were restarting themselves under mystical situations, that made it harder for them to obtain accessibility to the tools and essence information. Citing safety and security scientists, 404 Media later on reported that iphone 18 had a brand-new “inactivity reboot” function that required the tools to reactivate.
Now we understand specifically for how long it considers this function to begin.
On Wednesday, Jiska Classen, a scientist at the Hasso Plattner Institute and among the initial safety and security specialists to detect this brand-new function, released a video clip showing the “inactivity reboot” function. The video clip reveals that an apple iphone laid off without being opened reboots itself after 72 hours.
Magnet Forensics, a business that supplies electronic forensic items consisting of the apple iphone and Android information removal device Graykey, likewise verified that the timer for the function is 72 hours.
“Inactivity reboot” effectively puts iPhones in a more secure state by locking the user’s encryption keys in the iPhone’s secure enclave chip.
“Even if thieves leave your iPhone powered on for a long time, they won’t be able to unlock it with cheaper, outdated forensic tooling,” Classen wrote on X. “While inactivity reboot makes it more challenging for law enforcement to get data from devices of criminals, this won’t lock them out completely. Three days is still plenty of time when coordinating steps with professional analysts.”

iPhones have two different states that can affect the ability of law enforcement, forensic experts, or hackers, to unlock them by brute-forcing the user’s passcode, or extracting data by exploiting security flaws in the iPhone software. These two states are “Before First Unlock,” or BFU, and “After First Unlock,” or AFU.
When the iPhone is in BFU state, the user’s data on their iPhone is fully encrypted and near-impossible to access, unless the person trying to get in knows the user’s passcode. In AFU state, on the other hand, certain data is unencrypted and may be easier to extract by some device forensic tools — even if the phone is locked.
An iPhone security researcher who goes by Tihmstar told TechCrunch that the iPhones in those two states are also referred to as “hot” or “cold” devices.
Tihmstar said that many forensic companies focus on ” warm” devices in an AFU state, because at some point the user entered their correct passcode, which is stored in the memory of the iPhone’s secure enclave. By contrast, ” chilly” devices are far more difficult to compromise because its memory cannot be easily extracted once the phone restarts.
For years, Apple has added new security features that law enforcement have opposed and spoken out against, arguing that they are making their job harder. In 2016, the FBI took Apple to court in an effort to force the company to build a backdoor to unlock the iPhone of a mass-shooter. Eventually, the Australian startup Azimuth Security helped the FBI hack into the phone.
Apple did not react to an ask for remark.
