A recent investigation reveals that the FBI has successfully recovered deleted Signal messages from iPhones by targeting the device's local notification database. While Signal is widely praised for its end-to-end encryption and disappearing message features, the iOS notification system can store previews of incoming messages in a separate log on the device. This forensic technique allows law enforcement to bypass the primary app's security by accessing historical notification data stored within the operating system, highlighting a critical privacy vulnerability where system-level features inadvertently archive data that users intended to destroy.
