Spies in the Skies: Americans’ Cellphones Targeted in Secret U.S. Spy Program

WASHINGTON—Devlin Barrett reports: The Justice Department is scooping up data from thousands of cellphones through fake communications towers deployed on airplanes, a high-tech hunt for criminal suspects that is snagging a large number of innocent Americans, according to people familiar with the operations.

“The program cuts out phone companies as an intermediary in searching for suspects. Rather than asking a company for cell-tower information to help locate a suspect, which law enforcement has criticized as slow and inaccurate, the government can now get that information itself.”

The U.S. Marshals Service program, which became fully functional around 2007, operates Cessna aircraft from at least five metropolitan-area airports, with a flying range covering most of the U.S. population, according to people familiar with the program.

“Similar devices are used by U.S. military and intelligence officials operating in other countries, including in war zones, where they are sometimes used to locate terrorist suspects, according to people familiar with the work. In the U.S., these people said, the technology has been effective in catching suspected drug dealers and killers. They wouldn’t say which suspects were caught through this method.”

Planes are equipped with devices—some known as “dirtboxes” to law-enforcement officials because of the initials of the Boeing Co. unit that produces them—which mimic cell towers of large telecommunications firms and trick cellphones into reporting their unique registration information.
