Verizon to Stop Sharing Customer Location Data With Third Parties
Krebs on Security
In the wake of a scandal involving third-party companies leaking or selling precise, real-time location data on virtually all Americans who own a mobile phone, the four major wireless carriers have responded to requests from a U.S. senator for more details about how the carriers are managing access to this extremely sensitive information. While three out of four providers said they had cancelled data sharing agreements with some of the offending companies, only one — Verizon — pledged to terminate all of them and initiate a wholesale review of their location data-sharing practices.
At issue are companies known in the wireless industry as “location aggregators,” entities that manage requests for real-time customer location data for a variety of purposes, such as roadside assistance and emergency response. These aggregators are supposed to obtain customer consent before divulging such information, but several recent incidents show that this third-party trust model is fundamentally broken.
