“Devices capable of accessing calls, photos and text messages on cell phones were installed on two Texas National Guard surveillance aircraft. The project was funded by over $300,000 from drug-related asset forfeitures. The cell site simulators, known as ‘dirt boxes’ (after the company’s acronym, DRT), are designed to mimic cell phone towers and trick every smartphone within one-third of a mile into connecting with it.

The devices can also be used to record or listen to phone calls ‒ all of it without users or service providers knowing about it.”
