For more than a year, federal authorities pursued a man they called simply “the Hacker.” Only after using a little known cellphone-tracking device—a stingray—were they able to zero in on a California home and make the arrest. Stingrays are designed to locate a mobile phone even when it’s not being used to make a call.
