Our TCP game reset by hackers - here's how

Our multiplayer game has a small community of dedicated players. However, it does not deter a couple of morons from causing problems for us. The “hackers” basically telnet to our game IP/port, send a message and then close. This causes our games to reset. Since we do not have the game source code, is there any way for us to prevent this from happening, maybe a firewall setting..? The hackers say they know how to stop it.. Thank you

It sounds like it's a flaw in the game server software. If they're connecting to the same location the game client would, a firewall is not going to stop it. Do you know what message they're sending? Also, perhaps someone here is familiar with the game if you tell us the name.

They can send any message. It could be "1", so as long as they send something, then close. I didn't want to say the game name, since I don't want more hackers doing the same thing.

It's a small game. I don't think anyone here has heard of it, but I'll PM the name to you, if it will help?


Thank you for helping.

So if anyone connects to your server and sends data, the server crashes.

A strange game - the only winning move is not to play.




There must be more that I'm missing though, what you probably mean is that they send malformed packet or something similar.

Hmm, good point. Let me PM the bat file they are executing (hope it's okay).

That sounds like a major flaw in the server software. Sorry, I personally don't know that could I help. Other than looking for a patch from the people who made the game I am not sure what you could do.

Thanks

Yep, looks like it to me. Connect, send anything, and close and the room resets.
