First of all I would like to thank everyone who helped me in the previous post. I much appreciate it.
As you know I am trying to develop an up to date program that bypasses a firewalls outbound protection. In order to prove that they aren't that good.
Untill now we reverse engineerd backstealth (piorio.supereva.it/backstealth.htm). This basically gave us the idea on how to go to work. This did not give us a working version, merely the method. After that we reverse engineerd the dll. And here is where the problems arised. So we decided to write our own dll.
Now I have everything working. Except one thing I can not figure out. The dll injection works fine. I can even show message boxes from IE. But when the program wants to connect to the internet, IE suddenly uses 99% of my CPU and does NOT connect.
I can almost do everything from that dll. I can call everything that is inside libraries loaded by the process as it seems. But that is no problem, a browser has loaded kernel32 and wininet. As said the process hangs when i execute internet related functions. The functions are called froma thread that belongs to IE, i checked that. The firewall is disabled.
My question is when would such a problem occur? Is it my network perhaps? What would be the solution to this problem? Any tips and help are again very much appreciate it. I will mentione this board in the credits section when we publish it.
Thanks in advance!
