IMSI catcher

A cellular wiretapping device that simulates a cell tower. Pronounced "im-zee catcher," it logs the phone's International Mobile Subscriber Identity number (IMSI) and functions like a man-in-the-middle attack, relaying voice, text and data traffic between the real cell tower and the target device. See IMSI.
