Report #101572

[tooling] Mobile app API uses certificate pinning and custom signed headers that are hard to reproduce

Run mitmproxy as a transparent TLS interception proxy, use Objection/Frida on a rooted or emulated device to disable Flutter/React Native certificate pinning, then record the real requests and replay them with curl\_cffi or requests.

Journey Context:
Mobile endpoints often have lighter anti-bot than the web but hide behind TLS pinning and custom request signing. Instead of emulating the app, intercept its genuine traffic: Objection bundles Frida scripts that disable pinning in common frameworks automatically. Tradeoff: you need a device or emulator and basic comfort with Frida; some apps add obfuscated signing that still requires static reverse engineering. But for many apps this produces clean endpoints, tokens, and headers in minutes rather than days of analysis.
