FBI Recovers Deleted Signal Messages Through iPhone Notifications

The article reports that the FBI recovered incoming Signal message previews from an iPhone’s push notification database even after the app was deleted; the OS stores notification previews separate from the app and those previews can be extracted by forensic tools (e.g., Cellebrite). It warns this affects other messaging apps that show previews and recommends disabling notification previews in iOS and app settings to prevent data exposure.
