You likely have never heard of Babel Street or Location X, but chances are good that they know a lot about you and anyone else you know who keeps a phone nearby around the clock.
Reston, Virginia-located Babel Street is the little-known firm behind Location X, a service with the capability to track the locations of hundreds of millions of phone users over sustained periods of time. Ostensibly, Babel Street limits the use of the service to personnel and contractors of US government law enforcement agencies, including state entities. Despite the restriction, an individual working on behalf of a company that helps people remove their personal information from consumer data broker databases recently was able to obtain a two-week free trial by (truthfully) telling Babel Street he was considering performing contracting work for a government agency in the future.
Tracking locations at scale
KrebsOnSecurity, one of five news outlets that obtained access to the data produced during the trial, said that one capability of Location X is the ability to draw a line between two states or other locations—or a shape around a building, street block, or entire city—and see a historical record of Internet-connected devices that traversed those boundaries.
