The federal government has been fighting hard for years hide details about its use of so-called stingray surveillance technology from the public.
The surveillance devices simulate cell phone towers in order to trick nearby mobile phones into connecting to them and revealing the phones’ locations.
Now newly released documents confirm long-held suspicions that the controversial devices are also capable of recording numbers for a mobile phone’s incoming and outgoing calls, as well as intercepting the content of voice and text communications. The documents also discuss the possibility of flashing a phone’s firmware “so that you can intercept conversations using a suspect’s cell phone as a bug.”
The information appears in a 2008 guideline prepared by the Justice Department to advise law enforcement agents on when and how the equipment can be legally used.
The Department of Justice ironically acknowledges in the documents that
the use of the surveillance technology to locate cellular phones 'is an
issue of some controversy.'
The American Civil Liberties Union of Northern California obtained the documents (.pdf) after a protracted legal battle
involving a two-year-old public records request. The documents include
not only policy guidelines, but also templates for submitting requests
to courts to obtain permission to use the technology.The DoJ ironically acknowledges in the documents that the use of the surveillance technology to locate cellular phones “is an issue of some controversy,” but it doesn’t elaborate on the nature of the controversy. Civil liberties groups have been fighting since 2008 to obtain information about how the government uses the technology, and under what authority.
Local law enforcement agencies have used the equipment numerous times in secret without obtaining a warrant and have even deceived courts about the nature of the technology to obtain orders to use it. And they’ve resorted to extreme measures to prevent groups like the ACLU from obtaining documents about the technology.
