How to reverse engineer a binary with AI assistance in IDA Pro
When to use: You have a binary loaded in IDA Pro and want AI to help understand and annotate it.
Prerequisites
- IDA Pro 8.3+ (not IDA Free) — Commercial license from Hex-Rays
- ida-pro-mcp installed — pip install <repo-url> && ida-pro-mcp --install
Flow
-
Get an overviewList all functions in this binary. Which ones look like they handle network communication based on their names and imports?✓ Copied→ Categorized function list with network-related functions highlighted
-
Decompile key functionsDecompile the main network handler function. Explain the protocol it implements and rename variables to be descriptive.✓ Copied→ Decompiled C code with renamed variables and protocol analysis
-
Trace data flowFind all cross-references to the encryption key buffer. Who reads it and who writes it?✓ Copied→ Xref chain showing data flow from key generation to encryption calls
Outcome: A well-annotated IDB with key functions understood, renamed, and documented.
Pitfalls
- Decompilation can be slow on large functions — Start with smaller callees and work up. Use disasm() for quick overviews.
