"'Call of Duty' Players Are Being Hit With Self-Spreading Malware"

Hackers are targeting Call of Duty players with a massive malware push that can self-replicate and spread through the game's multiplayer lobbies. The malware infection appears to have been sufficient for Activision to take the game offline. Some members of the Steam community attempted to examine the malware, which was discovered to have a match in Virus Total's database. Based on the findings, the malware appears to be a worm that exploits security flaws in the application's code. That ability enables it to evade traditional protections against code injection. Once the malware infects a lobby, it can run localized code on the machines of the users accessing that session. Currently, malware infections have only been reported for the 2009-launched Modern Warfare II. However, given that different Call of Duty games released around 2009 are likely to share most of the same multiplayer code, other games in the series may be vulnerable to the exploit. This article continues to discuss hackers' recent targeting of Call of Duty players.
