If what you claim is correct, this could be very bad. The virus is already there on many infected machines, it just needs a way to communicate with other infected hosts to coordinate it's bidding. IRC has been a weak link for viruses as they can usually be tracked and stopped in a short order, however with gaming machines, it may be a little bit harder. Maybe there are no master servers. Maybe it doesn't need one. Perhaps it just uses a network like Game Spy to find public Halflife (or other gaming servers) to get the viruses to "link" together. Infected boxes would the communicate on random Halflife servers all over the net. (there are thousands of them). Maybe the clients don't find the masters, maybe the masters find the clients. Maybe the list of "20 servers" was just a decoy of sorts. It would be nearly impossible to track the source of who is controlling the infected boxes.
