frida-hooking

What problem does it solve?

This Skill eliminates the need for reverse engineers and Android security analysts to write boilerplate Frida scripts from scratch when dynamically instrumenting Android apps to trace execution, intercept function calls, and analyze sensitive logic in both Java and native layers.

Core Features & Use Cases

• Reusable Hooking Patterns: Pre-built templates for Java method hooking (including overloads, constructors, and field access) and native function interception via Frida's Interceptor API.
• Advanced Task Support: Built-in guidance and templates for common complex scenarios including JNI RegisterNatives tracking, syscall tracing with frida-strace, and Stalker-based code path tracing.
• Real-World Use Case: An analyst can use this Skill to quickly hook an app's native request-signing function to extract the HMAC key, or trace Java method calls to locate where sensitive user data is processed before transmission.

Quick Start

Use the frida-hooking skill to write a Frida script that hooks the target Android app's native sign() function to log its input parameters and return value for analysis.
