FBI extracted deleted Signal messages, even after the app was uninstalled.
When Signal messages arrive, iOS stores push notification previews locally on the device. In this case, those previews stayed behind even after Signal was uninstalled.
- Only incoming messages were captured this way
- Disappearing messages that had already vanished inside Signal were still recoverable from the notification cache
-This is iOS behavior, not a Signal vulnerability. And likely impacts other ALL apps on iOS.
The quick fix, to turn it off:
Signal → Settings → Notifications → Show → set to "No Name or Content"
You'll still get a notification ping, but iOS just won't cache anything useful.
The real fix:
Switch to GrapheneOS
