Proxying a game (for packet editing)

[zstars]

For what I know, an often used way to hack in multiplayer games is to make them connect to the game server through some kind of local proxy. That way, an external program can read the packets before they arrive at the server, and modify them or add new packets as required. I've been searching the net for tutorials on this topic, but I haven't really found any because I only find tutorials about how to find normal proxies.

Does anyone know any tutorial or something that might be of help for learning the best way to do this?


I've been thinking of ways to do this and I think it could be possible to program a modified socks proxy server and make the game connect to it using SocksPCap or whatever the program name was, but I don't wanna reinvent the thing, so I thought I would ask. (Anyway, in case I don't find a better way, does anyone know of any C/C++ open source socks proxy server?)

Well anyway, thanks for reading this and thanks in advance .

Umm, why use a local proxy, when you can just do it normally through your own IP, say with WPE or Etheral?

Most games you can't "make" route through a Proxy if any.

A packet sniffer would be enough to read the packets, but I want to be able to interact with the game server, modifying the packets the client sends before they arrive to that server, and adding new packets as if they had been sent by the client.

you can edit packets using a packet sniffer

Yeah, OFC.
WPE works fine in this situation. =)

I don't think WPE can intercept a packet and modify it in real time before it gets to the server.

Basically I want to make a bot, for a MMORPG. My program would work like this:

1-Client sends a packet saying "Move to coord 20, 20"
2-My program intercepts the packet.
3-My program decrypts the packet.
4-My program reads the packet and analyzes it.
5-My program modifies the packet to say, for example "Move to coord 20, 30".
6-My program encrypts the packet again and sends it to server.
7-Server receives the modified packet instead of the real one.

Ah, you are trying to make a bot.
That's totally different, you have to write a custom program yourself.
Or use someone elses...

I think I've seen a custom WPE somewhere, can't remember where. I think it was on the cheat engine forums. I'll upload it if I find it.

Ive been trying to hack a specific Iphone application for weeks and have no possible aspects on how to do it, however I can use an editor such as the custom one suggested above if anyone can help

[supercarz1991]

packet editing is illegal or you wouldf see hacks like god mode and such for every game on the net
