Website leaked real-time location of most US cell phones to almost anyone

A little-known service has been leaking the real-time locations of US cell phone users to anyone who takes the time to exploit an easily spotted bug in a free trial feature, security news site KrebsOnSecurity reported Thursday.

LocationSmart, as the service is known, identifies the locations of phones connected to AT&T, Sprint, T-Mobile, or Verizon, often to an accuracy of a few hundred yards, reporter Brian Krebs said. While the firm claims it provides the location lookup service only for legitimate and authorized purposes, Krebs reported that a demo tool on the LocationSmart website could be used by just about anyone to surreptitiously track the real-time whereabouts of just about anyone else.
