About:
RetDec is an open-source machine-code decompiler that translates binary executables into high-level C source code. It leverages LLVM-based infrastructure to perform sophisticated analysis, including instruction decoding, control flow graph reconstruction, and data type identification. This tool enables security researchers and developers to analyze and understand compiled software without access to original source code.
Key Features:
  • Supports multiple architectures (x86, ARM, MIPS, PowerPC)
  • Generates readable C code from machine code
  • Includes comprehensive analysis tools (config, fileinfo, decompiler)
  • Plugin-based architecture for extensibility
  • Cross-platform compatibility
Use Cases:
  • Malware analysis and reverse engineering of suspicious binaries
  • Legacy software maintenance when source code is unavailable
  • Security vulnerability research and exploit development analysis
  • Educational purposes for understanding compiler output
Alternatives:
  • Ghidra – NSA's open-source framework with GUI and decompiler, more feature-rich but heavier
  • IDA Pro – Industry-standard commercial tool with superior decompiler, expensive but comprehensive
  • radare2 – Lightweight CLI framework with decompiler plugins, more focused on analysis than decompilation
