Hacked Tesla Twitter feed leaves one phone ringing

Tesla Motors (TSLA)' verified Twitter feed and website seemed to be targeted by hackers Saturday.

The Twitter feed, found under the handle @TeslaMotors, changed to read #Ripprgang during the attack. One particular tweet promised a free Tesla car to people who called an offered phone number.

The Napierville, Illinois, phone number leads to a voice mail greeting that says, "There is no free Tesla," and asks callers not to call back.

Of course CNBC called back. The man who answered says he works in broadcasting in the Chicago area but asked that we not mention his name. He said the phone belongs to his 20-year-old son "who is freaking out" about the exposure.

He said the phone has received hundreds of calls since the tweet went up around 5 p.m.
