Research on Trojan communication model based on IRC and webmail system

Since Trojan has been used widely in various applications, modern Trojan requires a stronger anti-tracing performance than before. As an attempt seeking beneficial result, this paper proposes a new Trojan communication model based on Internet Relay Chat (IRC) and Webmail system. IRC chat channel is designed to transfer commands and Webmail system is applied to store data. Because of this design, it is not necessary to build a direct link between Trojan user and target hosts. Therefore, this model has a better performance on anti-tracing and the measuring data of response time proves its efficient real-time control performance.
