In some distant part of the mists o'time, I wrote a little tool who purpose was to report pending messages and other misc info for a thread and the windows it owns. It's safe to say this was tangentially useful at best.
That was until I saw somebody, somewhere, ask if there was a tool that would or could list currently active Windows hooks and had an idea. After that idea sank (pineapple juice and tea do not go together even if you like them both), I went and stuck hook enumeration together with message and window enumeration to add to my previous work of desktop heap enumeration. Yep, if you need things enumerating, you can count on me.
So here we have it, MsgLister + hooks = MsgHookLister. The download zip contains the source for the app and the driver that pokes into undocumented Windows structures as well as x64 and x86 binaries.
A screenie of window mode
And of hook mode - how exciting
Hmm, what to enumerate now...
