Abstract:
Recently, massive attacks on Fritz!Box hardware units have been disclosed, caused by a security vulnerability. The Fritz!Box by AVM is an multifunctional routing device, offering Voice over IP-(VoIP) and internet connectivity to private users, which is in wide use in Germany. By first taking over the units and in a second step using the units to conduct toll fraud attacks on VoIP providers and their customers, significant financial damage has been caused. In this work, these attacks are analyzed and attack patterns as well as their characteristic traits are described. Based on these results, a novel method for toll fraud detection is devised and evaluated. The method is capable of detecting this kind of attack, as well as similar attack patterns. Results of a prototype implementation show successful detection of these attacks, enabling to prevent them in the future. This work is based on real-life traffic data from a cooperating telecommunication service provider.
