FBI used the flaw to extract readable Signal messages from an iPhone’s notification database even after the app was deleted.
Tech giant Apple has fixed a security flaw that had allowed the FBI to access a Signal user’s deleted messages through their phone’s push notification database, despite the app being deleted and messages being set to disappear.
In a security advisory released on Wednesday, Apple said it had fixed a bug that allowed “notifications marked for deletion” to be “unexpectedly retained on the device.”
In an X post on Wednesday, Signal said the update fixed the issue that made a user’s messages retrievable by law enforcement.
