Abstract:
University of Minnesota researchers have discovered cellular networks leaking the locations of their subscribers. Using a cheap feature phone and an open-source project, attackers listen to unencrypted broadcast messages from the towers to determine victims in the vicinity. The researchers introduce cheap and easily deployable defenses for the core network.
