CIPPIC, the Samuelson-Glushko Canadian Internet Policy & Public Interest Clinic, and Citizen Lab are releasing a report, "Gone Opaque? An Analysis of Hypothetical IMSI Catcher Overuse in Canada", which examines the use of devices that are commonly referred to as ‘cell site simulators’, ‘IMSI Catchers’, ‘Digital Analyzers’, or ‘Mobile Device Identifiers’, and under brand names such as ‘Stingray’, DRTBOX, and ‘Hailstorm’. IMSI Catchers are a class of of surveillance devices used by Canadian state agencies. They enable state agencies to intercept communications from movie devices and are principally used to identify otherwise anonymous individuals associated with a mobile device and track them.
