SSL Pinning Bypass — Hardened Apps

Certificate pinning makes a mobile app refuse a connection even when normal TLS validation says yes — and on a hardened app, the generic Frida one-liner that beats it everywhere else simply stalls. The reason is where the pin lives. This walks the trust + pin gates, the call-stack layers a pin can hide in (custom TrustManagers, OkHttp, native), how an assessor validates pinning on an app they own, and how to build pinning that survives a MITM and your own cert rotation.
