Abstract
Most of the traditional IMSI catcher attacks would not work against LTE (4G) mobile phones. This is due to the fact that LTE is more secure than old generations technologies. In this talk, we build an IMSI catcher to investigate LTE security mechanisms in practice and show how popular smartphones fail during a live demo. In addition, we discuss common LTE configurational mistakes of mobile network operators and smartphone vendors that allow IMSI catcher type of attacks.
