Apple's iOS 18.1 Update Adds Automatic Reboot to Thwart iPhone Unlocking
A new feature in iOS 18.1 automatically reboots iPhones after four days of remaining locked, blocking common police password-cracking tools. Security experts praise the update as a major win for user privacy that causes minimal inconvenience to everyday users.
A new feature in Apple's iOS 18.1 operating system makes iPhones significantly harder for police and thieves to unlock. The update introduces an automatic reboot mechanism that activates if a phone stays locked for an extended period, specifically triggering after four days of inactivity. Law enforcement officials recently alerted each other about this change after noticing devices stored for forensic examination were mysteriously restarting themselves.
Once the iPhone completes this automatic reboot, it enters a state that renders standard password-cracking tools ineffective. Security researchers from mobile analysis firm Corellium confirm this behavior, noting that the reboot process resets the device's security posture. Johns Hopkins cryptographer Matthew Green calls the update a huge improvement in terms of security, pointing out that it probably does not inconvenience normal users in their daily lives.
Apple remains quiet on the update as the company does not immediately respond to requests for comment. However, the change represents a significant roadblock for law enforcement agencies that rely on third-party tools to access seized devices during criminal investigations. By closing this security loophole, Apple continues its long-standing trend of prioritizing consumer privacy over providing convenient access to government authorities.
