Hi, I am looking for help in hacking an online game

I have a basic idea of how CE's speedhackworks ( I think). I think it injects a dll, and changes the value of QueryPeformanceFrequency.

What I want to know is, how can a game detect this and what could I do to circumvent their anti-cheat measures.

So far I have tried both the new and old Speedhack, using CE 5.6.1 and both cause the game to instantly close.

The game has its own protection program, but is written for 32 bit rather than x64, which has allowed me to delete the protection program and still allow me to run the game.

I also cannot seem to use the "Find out what writes to this address" or "Find out what accesses this address" functions, even with the kernel mode debugger. (It closes the game when I try to full screen it)

I have experimented with OllyDbg, and have managed to get it to open/ attach to the game, but I am not sure what im doing there. Also I am almost 100% sure that it isnt using IsDebuggerPresent to detect any debuggers, because the hide olly tools that were meant to hide it from that did not work. (I used AntiDetectOlly2.24.exe to get it working in the end.)

Anyone can help me?

We do not support multiplayer game hacking here anymore.

as long as it doesn't contain information on which game it is and no game code is posted it's ok

For debugging try ce's veh debugger

As for why the speedhack is detected:
Perhaps it sends a packet to the server containing the current time
So if it sends a packet after 10 seconds saying that time has passed 20 seconds the server kills the client

Thanks for your advice, I have now found the pointer.

However, I don't think the speedhack prevention mechanism is anything based on what you suggested. Otherwise it would not close as soon as iclick the speedhack button. ( Speed is set at x1 till i change it).

I was thinking that too, but I am not sure. I have tried looking up methods of preventing dll injection detection but so far no luck.
