IL2CPP changes where the evidence lives
Unity documents IL2CPP as an ahead-of-time backend that converts managed assemblies to C++ and compiles the result into native code. On Android, the package commonly contains libil2cpp.so and Unity metadata. The normal DEX can hold the Android player and plugins while the C# application logic lives in the native Unity build.
Method names, types, fields and serialized structures can still be recovered by joining metadata with native registrations. We map those structures first. This gives network code a useful shape before runtime tracing begins.
Follow requests across Unity and Android
A Unity app can send traffic through UnityWebRequest, a managed library, a native SDK or an Android Java plugin. One login may cross several of them. We trace the request from the game state that creates its inputs through serialization, compression, signing and transport.
IL2CPP-generated code often builds request values through shared helpers. We recover the helpers once, then apply them across the endpoint set. Native plugins receive separate analysis when they create tokens, device fingerprints or encrypted payloads. Asset bundles and configuration files are checked for hosts, route templates and environment settings, then confirmed against live behavior.
The full APK becomes a full callable API
We rebuild the application’s complete server-facing behavior. The delivery includes Python, JavaScript and TypeScript clients, an importable Postman collection, and working request examples. Authentication, cookies, refresh rules, request order and error handling are built in.
Signature generation runs with fresh timestamps and nonces. Encryption and decryption are implemented in code. Binary bodies are serialized correctly. Each client can start a new session and repeat the application workflows without reusing an old capture.
We test the clients against the same server flows used by the APK. Send the APK on WhatsApp or by email. We handle the technical questions in the conversation.
