Abstract
Systems and techniques are provided for detecting rogue base stations and preventing malicious actors from intercepting and stealing data traffic from mobile devices through rogue base stations. Upon connecting to a newly detected base station for a cellular network service, a mobile device attempts to validate the cellular base station with a validation server before any data is transmitted over the new connection. If the mobile device does not receive a confirmation of validity from the validation server, the mobile device would identify the cellular base station as a rogue base station, disconnect from the rogue base station, and search for a valid base station for connection to the cellular network.
