Original Abstract Submitted
Systems and methods are provided for mitigating malicious attacks by IMSI-catchers. IMSI-catchers act as “fake” towers to intercept mobile device traffic and obtain private user data. These unauthorized devices pose a serious risk to user privacy. Aspects herein detect the presence of IMSI-catchers using RF footprints of cell sites to detect changes in RF footprint metrics that indicate the presence of IMSI-catchers. Once detected, beamforming techniques can be used to target a specific area surrounding the IMSI-catcher with a high-powered beamform that emits at a power level higher than the IMSI-catcher in order to reacquire any user devices that may have unknowingly connected to the IMSI-catcher.
