Project Description

I need someone that have experience in developing anti hack in the past.

My situation is a server MMORPG that receive connection in 6 ports TCP each is a gameserver where the client stay connected, the ports are:
55901
55902
55903
55904
55905
55906

If I put netstat -n will return many things and the people connected on those ports like:
TCP [url removed, login to view] [url removed, login to view] ESTABLISHED
TCP [url removed, login to view] [url removed, login to view] ESTABLISHED
TCP [url removed, login to view] [url removed, login to view] ESTABLISHED
TCP [url removed, login to view] [url removed, login to view] ESTABLISHED
TCP [url removed, login to view] [url removed, login to view] ESTABLISHED
TCP [url removed, login to view] [url removed, login to view] ESTABLISHED

That mean each of this IP are playing in one gameserver different.

I current have a anti hack [url removed, login to view] that close the hack programs that are running in memory or proccess or hidden in ring level 3 or anywhere in the computer, the big problem is that people create a bypass [url removed, login to view] that can jump it.

To solve the problem I got one idea, close the connection that when checked is not running the current anti hack GHP.

To close the connection the program get the IP by running netstat -n and only are connected to the gameserver port, them with the client IP it send a packet to client where it ask for a verification, some hash that will not be possible bypass, and the client will be running a dll or some .exe software that will receive this information into a TCP port and will check in memory if the GHP is running, if is running return to the server that everything is fine, server receive it and nothin happen. If the client are not able to provide the return message coded with some hash that is not possible bypass, them the server will execute the netsh command to block that IP address and save the data server block it to unblock after 2 hours.

To make the IP client block we can use netsh or we can use a open source software called Qaas Firewall [url removed, login to view] by a command like [url removed, login to view] IP client it block it, and with other like [url removed, login to view] IP client it unblock it.

This is my idea to fix the bypass problem one time I do not have source code of GHP but I can talk with them to include my DLL in my compilation so I can make a way to avoid bypass and can keep the safe anti hack solution of GHP that can close alot of programs, cheats, hidden and everything.

I want people to make it in C or C++, because the Java or Delphi or other languages will need frameworks and most of clients do not have it. But C or C++ do not need framework and if need, will be one allready came with the game that is the Microsoft Visual C++ 6.0. But is best do not need it. I put people know Assembly because maybe someone know a way to fix that, one time the bypass are made by using OllyDbg or something related with Assembly.

I am open for other ideas for anti hack solution, I prefere to talk with people that allready have done in the past something similar.
