Earlier this week, the United States Computer Emergency Readiness Team (US-CERT) released an advisory regarding the GameOver Zeus P2P Malware. Along with that advisory was a national press release from the US Department of Justice and the FBI that announced a multi-national effort against the GameOver Zeus botnet.
GameOver Zeus, a.ka. P2P Zeus, is a sophisticated type of malware that is used by cybercriminals to steal infected hosts' banking information, install other malware, and perform DDoS attacks and other cybercrime-related activities. It is estimated that this botnet has earned over $100 million since 2011 from its victims.
The Fortinet botnet monitoring system has been tracking this botnet for some time now and has been able to catch it performing its critical update in April. This update included some rootkit functionalities that would make it more difficult for Zeus to be removed from infected systems.
Fortinet will continue to monitor the activities of this botnet. With law enforcement agencies actively taking steps to take it down, we hope that this botnet's operations will soon decline
