California secretly listened to cellphone calls from the air
The CIA-developed “Dirtbox” can monitor thousands of people at a time.
If you had cellphone problems in Orange County within the last few years, you may have been the unwitting victim of a secret cellphone surveillance program, according to the ACLU. Since 2009, the Anaheim Police Department has used the Dirtbox, a military-grade, Stingray-type device that can be mounted on light aircraft. While airborne, it mimics a cellphone tower in order to indiscriminately intercept and record thousands of cell phone calls.
While Anaheim is a relatively small city, police may have also loaned out the device to other Orange County municipalities. As a result, the program “potentially affects the privacy of everyone from Orange County’s 3 million residents to the 16 million people who visit Disneyland every year [and] shows the dangers of allowing law enforcement to secretly acquire surveillance technology,” says ACLU policy attorney Matt Cagle.
The systems overpower regular cellphone towers, so they can potentially disrupt regular mobile networks. “Until now, the only reported domestic use of these powerful devices was by the federal government and the cities of Los Angeles and Chicago,” according to Cagle. However, the CIA recently gave local law enforcement agencies permission to use the devices. The city also bought a Stingray system (above) in 2011, and may have purchased a hand-held device called a Jugular, which allows officers to surreptitiously intercept LTE signals inside buildings.
