Hacker talks to Arizona man through the Nest security camera in his home

A north Phoenix resident said he wants to warn others that these devices aren't as secure as you may think. Andy Gregg, a real-estate agent in north Phoenix, says a hacker spoke to him through his Nest security camera. Andy Gregg was in his back yard a few weeks ago when he heard a voice he didn't recognize inside his house. It was dark, and Gregg, who lives in the north Phoenix, said his first thought was somebody had broken into his home. The source of the voice surprised him: It was coming from a Nest Cam IQ security camera in his front window.
