Beware: Tech support phone call scam.

I just got a phone call from a woman with a very thick Indian accent claiming that my computer's IP address was now public and my computer was being hacked. She even transferred the call to the "Main Macintosh Server" department to speak with someone named John Williams who provided this phone number:
(855) 876-6657.
I immediately called the Apple Store and they agreed it was a scam.
Please beware.
