The National Computer Emergency response Team of Poland, CERT Polska has published a detailed report about the version of ZeuS botnet known as Gameover or ZeuS-P2P. This report contains information that should enable the average user to understand the nature of the threat, and show how one can identify an infected computer.
This version of the botnet utilizes a P2P (Peer-to-Peer) network topology to communicate with a hidden C&C and deploys a Domain Generation Algorithm (DGA). The report includes knowledge derived from infected computers and some of new features when compared to the classic ZeuS botnet.
