Ars Technica reports Cities reluctant to reveal whether they’re using fake cell tower devices "For some time now, the American Civil Liberties Union (ACLU) has been on a quest to better understand the use and legality of ‘stingrays.' These devices, which are also known as international mobile subscriber identity (IMSI) catchers, or fake cell towers, can be used to track phones or, in some cases, intercept calls and text messages.
The ‘Stingray’ itself is a trademarked product manufactured by a Florida-based company, the Harris Corporation. (It has since come to be used as a generic term, like Xerox or Kleenex.) Harris is notoriously secretive about the capabilities of its devices and generally won’t talk to the press about their capabilities or deployments."
