No Dedicated Servers for COD:MW2, Viruses Instead
 

Reported in a forum post on the official IW forums and our very own forums apparently hackers have found a way to go around the IW.net system and send a Trojan virus through the IW.net system to Modern Warfare 2 players. Reverse engeneering the source code for Modern Warfare 2, the hackers inserted their Trojan and used the IW.net system to spread it to players across the globe. This was brough to light after several players got notified of a breach in their security by their antivirus software. The Trojan TR/Crypt.XPACK.Gen had been sent to them using Modern Warfare 2's IW.net as the official transmitter (according to the antivirus). The Trojan itself apparently already surfaced in Call of Duty : World at War and is some sort of keylogging software hackers use to steal keycodes or potentially worse (stealing credit card information for instance).
