I've never heard of a specific computer being maliciously attacked while in game, either by an outside intruder or by an in-game intruder. The game is safe enough that you can play without any firewall at all (although not recommended, just in case). I have heard of hacked games, in other words, wirehacks or aimbots. But those have no effect whatsoever on any players, aside from giving the hacker the advantage through wireframes (also known as the map geometry), etc.
I know all that above may not be the clearest thing I've ever written, so if you don't understand any aspect of it, feel free to post and I'll fill you in some more...
