Hey guys, I'[ve been looking into this for the last 20 minutes and i just found something interesting.
From the mac os (particularly safari), when you go to google.com it sends you to sogosearch.com
I've got a feeling some hacker cleverly hijacked the DNS listing by hacking a registrar rather than google themselves. Google is clearly aware of the problem, because their IP address keeps changing every three seconds. It won't do anything, though, until they can get ahold of whatever ISPs DNS logs got hacked.
That's me just sputtering mumbo jumbo I don't have a great grasp on.
