The text of the attack was "This you????" with a link to a bogus website asking me to sign in. Wonder how many people turned over their password, and I also wonder how much twitter passwords go for on the black market?
I've seen these sorts of things on MSN, where the MSN account has been hacked and posts messages to all their friends with something along the lines of "LOL! Is this you in the photo? [link] Where then the user clicks the link and is prompted with a page where they must enter their MSN login information to access the photo.
