Frida TLS Pinning

Use this skill when HTTPS traffic is blocked by certificate pinning or custom trust validation.

Identify The Stack First

• Android Java: OkHttp, TrustManager, Conscrypt, WebView, network security config.
• Android native: BoringSSL, OpenSSL, Cronet, proxygen, Flutter engine.
• iOS: NSURLSession, delegate trust challenges, SecTrustEvaluate*, native BoringSSL.
• Cross-platform: React Native, Flutter, Unity, custom native networking.

Do not start with a universal bypass as the final answer. Use public scripts to discover which hook fires, then keep only the needed hooks.

Android Probe

Java.perform(() => {
  for (const name of [
    "okhttp3.CertificatePinner",
    "com.android.org.conscrypt.TrustManagerImpl",
    "javax.net.ssl.SSLContext"
  ]) {
    try { console.log("found", name, Java.use(name)); } catch (_) {}
  }
});

iOS Probe

if (ObjC.available) {
  for (const name of Object.keys(ObjC.classes).filter(n => n.includes("Trust") || n.includes("Session"))) {
    console.log(name);
  }
}

Native Probe

for (const m of Process.enumerateModules()) {
  if (/ssl|crypto|boring|cronet|liger/i.test(m.name)) console.log(m.name, m.base, m.path);
}

Verification

• Proxy is trusted by the device or app profile.
• The hook logs during the exact request that was blocked.
• The same request succeeds after mutation.
• Traffic is visible or the app behavior proves trust validation was bypassed.
• The final script documents app version, platform, library, and rollback command.
