Last year, a media investigation revealed that a Florida-based data broker, Datastream Group, was selling highly sensitive location data that tracked United States military and intelligence personnel overseas. At the time, the origin of that data was unknown.
Now, a letter sent to US senator Ron Wyden’s office that was obtained by an international collective of media outlets—including WIRED and 404 Media—claims that the ultimate source of that data was Eskimi, a little-known Lithuanian ad-tech company. Eskimi, meanwhile, denies it had any involvement.
Eskimi’s alleged role—and its denials—highlight the opaque nature of the location data industry: A data broker in Florida claims a Lithuanian company provided data on US military personnel in Germany. That data could theoretically be sold to essentially anyone. But the exact ways in which the data is collected, compiled, and shared remains unclear.
