zynamics BinNavi is the leading open source binary code reverse engineering tool
based on graph visualization

BinNavi is a binary code reverse engineering tool that was built to assist vulnerability researchers who look for vulnerabilities in disassembled code.

With BinNavi you can analyze disassembled x86, ARM, PowerPC, and MIPS code using the powerful built-in static code analysis techniques. In cases where static code analysis is not enough, you can use the built-in debuggers to get a live view on the program you are analyzing.

The code is available on GitHub.

Note: This product is no longer under active development.
Use Cases
  • Do control flow based code analysis of disassembled x86, ARM, MIPS, and PowerPC code
  • Cut down on complexity by removing unimportant code from functions
  • Use powerful remote debuggers to debug programs on different operating systems
  • Use Differential Debugging to quickly locate relevant code
  • Create and assign user-defined tags to mark important functions and basic blocks
  • Use advanced code analysis algorithms to keep track of data and code
  • Manage all your reverse engineering projects in one central database
  • Write scripts and plugins to extend BinNavi to meet your specific goals
  • Rename and annotate variables and functions to make them self-explanatory
  • Use the REIL meta-language to write platform-independent program analysis code

GDB Agent
Out of the box BinNavi can debug applications on 32-bit Windows, 32-bit Linux, and Windows Mobile. To debug devices that run a GDB server, BinNavi also includes a debugger GDB Agent.

The GDB Agent can be used to debug a wide variety of devices like Cisco routers or Netscreen firewalls.
