“Can get you in a lot of trouble”

Review by Nathan Wessler

From the maker of the Stingray, this device provides the added power to listen in on calls and read text messages. Also useful for kicking nearby phones off the network (you can choose between just blocking a single target phone or scrambling the signals of all phones in the area). Take note: Wiretapping calls and text messages requires a special “superwarrant” signed by a judge. Playing around with a Blackfin without adequate court supervision can get you in a lot of trouble.


BLACKFIN II adds more performance and capability to the Blackfin system while keeping the same compact package. BF II is designed to body worn or packaged for concealed missions. Can be discretely configured and controlled via blue tooth with the Mobile controller. Quad Band interrogator that can conduct passive monitoring survey, Interception of GSM voice and SMS of a preloaded target lists, blanketed or targeted denial of service, and geo a given GSM handset.
