In article 8 of my exploit writing series, I have introduced the concept of egg hunters, and explained what an omelet hunter is and how it works. Today, I want to share with you my own eggs-to-omelet implementation, explain how it works, and how you can use it in a standalone exploit or in a metasploit module. In case you missed article 8, I’ll start with a short recap and explain the basic concepts of egg hunters and omelet. At the same time, I would like to mention that you might have to read article 8 first before you will understand this post.  This post is not a full blown tutorial, …

When I started Win32 exploit development many years ago, my preferred debugger at the time was WinDbg (and some Olly). While Windbg is a great and fast debugger, I quickly figured out that some additional/external tools were required to improve my exploit development experience. Despite the fact that the command line oriented approach in windbg has many advantages, it appeared not the best tool to search for good jump addresses, or to list non-safeseh compiled / non-aslr aware modules, etc….  Ok, looking for a simple “jmp esp” is trivial, but what if you are looking for all pop pop ret combinations in non-safeseh compiled modules…   Not an easy task. It is perfectly possible to build plugins for Windbg, but the ones that I have found (MSEC, byakugan (Metasploit)) don’t always work the way I want them …
