Apparently, some time this evening, comcast.net (Comcast's user portal) got hacked. That, or Network Solutions has been hacked, and Comcast was their first target. I didn't get a screen shot, but this was the text on the page:

There was also an unsafe javascript that got blocked by NoScript, but it was down before I could analyze it.
