The documents described and linked below, instruction manuals for the software used by Stingray operators, were provided to The Intercept as part of a larger cache believed to have originated with the Florida Department of Law Enforcement. Two of them contain a “distribution warning” saying they contain “Proprietary Information and the release of this document and the information contained herein is prohibited to the fullest extent allowable by law.”
Although “Stingray” has become a catch-all name for devices of its kind, often referred to as “IMSI catchers,” the manuals include instructions for a range of other Harris surveillance boxes, including the Hailstorm, ArrowHead, AmberJack, and KingFish. They make clear the capability of those devices and the Stingray II to spy on cellphones by, at minimum, tracking their connection to the simulated tower, information about their location, and certain “over the air” electronic messages sent to and from them. Wessler added that parts of the manuals make specific reference to permanently storing this data, something that American law enforcement has denied doing in the past.
