Lol, I made something similar. Its a dll Injector with the DLL embeded into the exe itself. Also, in order to start the injection thread, you would have to login using the GUI provided. It would then format the given information into Post data which it would then send to /forum/login.php and it would return a result whether or not you succeeded.
The injector and the explanation is released on my blog, under the release section.
However, you should probably know that I asked Dave/Arun about it, and they added some sort of extra protection for logging in, some sort of salt maybe, im not sure.

Obama said it was alright to post a link to my blog, since I'm not really releasing any hacks on there. Anyways, Have fun. Good luck.
