35. Building a Hybrid Reversing Routine with Ghidra + Frida

Static analysis shows structure, while dynamic analysis shows real behavior. Combining the two tools in CTFs or real-world analysis dramatically increases speed.

Minimal Routine​

  • First mark core functions and string flows in Ghidra
  • Hook suspicious function addresses with a Frida script
  • Collect arguments and return values in logs to verify control flow
  • Find conditional branch points and trace input values backward

Ready-to-Use Frida Snippet Ideas​

  • Dump function-call parameters with Interceptor.attach
  • Immediately inspect important buffers with a hexdump
  • When something fails, re-hook based on the exception message

The key is the flow: “narrow the candidates statically, then confirm them dynamically.” Analysis speed is performance, and performance is the win rate.
