OS Notifications Leak Private Messages

Operating‑system push notification logging can unintentionally preserve parts of supposedly ephemeral, end‑to‑end encrypted messages and make them recoverable to forensic tools even after apps are deleted. Device vendors' logging, retention, and redaction practices therefore constitute a distinct attack surface for surveillance that sits outside application‑level encryption guarantees. — This reframes debates about secure messaging: platform and OS behavior — not only app crypto — can undermine user privacy and shift the balance of power toward law enforcement and prosecutors.
