Apple Patches iPhone Bug Exposing Deleted Messages

Apple released a software update on Wednesday for iPhones and iPads, addressing a significant security flaw. This bug had inadvertently enabled law enforcement agencies to recover messages that users had deleted or set to disappear automatically.

The issue stemmed from cached notifications, which retained message content on devices for up to a month. Apple acknowledged this vulnerability in a security notice, stating that notifications marked for deletion could be unexpectedly kept on the device.

This fix follows a report detailing how the FBI successfully extracted deleted Signal messages from an iPhone. The method exploited the fact that notification content was stored in the device's database, persisting even after deletion within the app. Signal's president had publicly urged Apple to resolve this retention problem.

Privacy advocates have expressed concern over this oversight, especially for at-risk users who rely on message auto-deletion features for security. The update backported to older iOS versions ensures broader protection against this loophole.
