What they're not telling you: Restore the Fourth (RT4) just released a technical audit regarding Signal’s "forensic footprint" on various operating systems. The TL;DR: While Signal’s SQLCipher encryption is solid, your OS is likely snitching on you.
# THE TAKE: Signal's Notification Problem Isn't Encryption—It's Architecture RT4's audit exposes what we already knew: Signal's end-to-end encryption is mathematically sound. The actual vulnerability? OS-level notification systems that broadcast message metadata before Signal's app even touches the data. Here's the provocation: this isn't a Signal flaw. It's a *feature* of how modern operating systems were designed—to leak. Android and iOS notification stacks are surveillance apparatus masquerading as UX conveniences. Signal can't patch an OS architecture. The real takeaway NSA contractors won't admit: if your threat model includes device-level adversaries, no mobile app solves this. Full disk encryption at rest means nothing when the OS kernel itself is exfiltrating plaintext notification content in real-time. RT4's audit matters precisely because it documents what should be obvious: your phone's operating system is the actual adversary. Signal's just honest about the limits.
