深度分析Instrumentation

Frida 是我们 Android 逆向的核心武器。通过运行时 Hook,无需源码即可拦截任意 Java 层与 Native 层函数调用,提取加密密钥、签名盐值、鉴权 Token。Frida is our core weapon for Android RE. Via runtime Hooks, we intercept any Java or Native layer function call without source code — extracting encryption keys, signing salts, and auth tokens.

配合脱壳、抓包与协议分析,形成完整的逆向研究闭环。Combined with unpacking, traffic capture and protocol analysis, we form a complete reverse engineering research loop.
