A roaming-based denial of service attack on LTE networks: poster.

During the last ten years, mobile communications greatly evolved. Along this process, the main goal was to satisfy users' needs such as coverage, communication speed, and availability. However, less attention has been posed to prevent attacks such as Denial of Service (DoS), which aim to render the mobile network unserviceable. In this paper, we present a novel method to implement a distributed DoS attack on a target mobile operator's Control Network. We exploit the lack of coordination between local and remote components of the LTE network during the roaming authentication process to realize a pulse DoS using temporal lensing. Finally, we discuss the feasibility of our attack on future 5G networks.
