Tell HN: DNS hacked? Redirected to forward.rewardfinds.com?

This problem popped up for me about a week ago. Requests to retail websites would be redirected to forward.rewardfinds.com, which then redirects to the requested website. I imagine rewardfinds is some affiliate program. I thought perhaps some malware, but after trying it on both a Windows and Ubuntu box, I suspected DNS. Flushed my DNS cache, switched over to 8.8.8.8 & 8.8.4.4 (Google's DNS) and that solved the problem.

Didn't think much of it, but a friend pinged me with the same problem. Did a search and it appears others are having the same problem (http://support.mozilla.com/mr/questions/766714).

At first I thought it was some nefarious tech at my ISP who figured s/he'd earn some extra bucks redirecting everyone's requests, but it appears more widespread.

Has DNS been hacked?
