Signal vs Wire — binary analysis of both APKs (apktool, strings, ELF inspection).

The gap is larger than most people think:

Signal: Rust core (libsignal_jni.so), Kyber-1024 post-quantum hybrid ratchet, SQLCipher for at-rest encryption, SVR with Intel SGX attestation, IME_FLAG_NO_PERSONALIZED_LEARNING (keyboard can't index your messages), zero third-party trackers.

Wire: Kotlin/Ktor, no hardened native core (more accessible to Frida), no SQLCipher (messages extractable in plaintext on rooted devices), no post-quantum, Segment SDK for behavioural telemetry.

But the finding that surprised me most:

Wire APKs from unofficial stores (Uptodown et al.) contain additional tracking workers and ACCESS_SUPERUSER permission requests not present in the official build. Supply chain integrity is not a footnote — it's the threat model.

Conclusion: Signal is the only one of the two suitable for threat models involving physical or administrative device compromise.

Static + dynamic analysis of Signal's APK. The good news first: Signal is genuinely exceptional.

Rust core (libsignal_jni.so), post-quantum hybrid Double Ratchet (Kyber-1024 + X25519), Direct ByteBuffers with immediate zeroing after PIN/username hashing, Intel SGX attestation for SVR — MREnclave verification means even a compromised Signal server can't extract your PIN hash.

But two things stood out:

1. Firebase is always there. Google receives IP + notification timestamps regardless of message content. If you need metadata privacy, Signal still leaks presence data to Google's infrastructure.

2. Certificate revocation endpoints hit http://g.symcd.com in plaintext. An ISP or state-level observer can fingerprint Signal usage from DNS queries and HTTP traffic to those CAs — without touching message content.

Conclusion: strongest crypto engineering in consumer messaging. The attack surface isn't the cryptography. It's the operational dependencies.
