Can rev-symbol detect specific encryption algorithms?

Yes, it specifically looks for magic numbers and constants associated with MD5, AES, CRC32, Zlib, and other common cryptographic and compression standards.

What prerequisites are needed to use rev-symbol?

You must first export your decompilation data from IDA Pro using the IDA-NO-MCP plugin, which generates the required .c files, strings.txt, and import/export tables.

Is rev-symbol limited to a specific CPU architecture?

No, because it analyzes decompiled C code and metadata exported from IDA Pro, it is architecture-agnostic as long as the decompiler can produce C output.

How does it name functions that have no direct strings or constants?

It uses cross-reference analysis, looking at the symbols of functions that call it or are called by it, and identifies paired patterns like 'alloc' followed by 'free' to infer its purpose.

セキュリティとテスト

Restores function names and symbols in decompiled binaries by analyzing code patterns, constants, and cross-references.

rev-symbol is a specialized reverse engineering capability designed to work with Claude Code and IDA-NO-MCP exported data. It automates the identification of anonymous functions by examining internal characteristics such as cryptographic magic numbers, string references, and common API call patterns. By performing deep cross-reference analysis of callers and callees, it reconstructs the semantic meaning of binary code, providing security researchers and developers with high-confidence symbol suggestions and detailed reasoning for faster malware analysis or legacy code recovery.
