You Can Run, But You Can't Hide: Exposing Network Location for Targeted DoS Attacks in Cellular Networks

Free registration required

Executive Summary

An important class of attacks against cellular network infrastructures, i.e., signaling DoS attack, paging channel overload, and channel exhaustion attack, operates by sending low rate data traffic to a large number of mobile devices at a particular location to exhaust bottleneck resources such as radio resource and radio resource controller. The authors term this class of attack targeted DoS attack on cellular networks, given the focus on a specific location. The success of such attacks depends on an important but unvalidated assumption that it is possible to create a relatively accurate hit list of mobile devices associated with the target network location to which attackers can direct traffic.
