Trapping and analyzing malicious VoIP traffic using a honeynet approach

Since several years the number of VoIP (Voice over IP) infrastructures increases and, consequently, the number of VoIP users increases too. Under these circumstances VoIP systems get more and more attractive for attackers, since the probability of successful attacks increases and attackers gain benefits, e.g., money with fee-based telephone numbers. Therefore, this paper describes a solution to capture, monitor and report VoIP attacks to gain more knowledge on current and new VoIP attacks.
