Today Adrian Dabrowski gives his talk “Towards Carrier Based IMSI Catcher Detection” at the TelcoSecDay 2016.
Abstract: In this presentation we discuss multiple detection capabilities of IMSI Catchers (aka Stingray) from the network operator’s point of view. We draw a comprehensive picture on current threats against mobile phone devices and networks, including 2G, 3G and 4G IMSI Catchers and present detection and mitigation strategies under the unique large-scale circumstances of a real European carrier. One of the major challenges from the operator’s point of view is the fact that cellular networks were specifically designed to reduce global signaling traffic, and manage as many transactions regionally as possible.
