New Tool for Visualizing Binaries With Ollydbg and Graphvis released

Sometimes crackme’s or something you might be reversing will constantly bug you due to the excessive usage of f7 & f8. It will be quiet neat if you can see how the application is executing visually and set your break points accordingly.

o Ollyscript plugin
o Bunch of your favorite anti-­‐debug plugins (phantom , ollyadvanced, …etc) o Pygraphviz
o Graphviz
o Python 2.7


  • Create an ollyscript that will do the following

    o Log all EIP for main application
    o Disregard to log calls to kernel32 , ntdll & addresses which are above

    7C000000 using step over not step into include more addresses to

    exclude if needed later for other system dll’s 77000000 … etc. o Save EIP Logs to file

  • Parse the log file
  • Feed it into pygraphviz
  • Export to png
