For those of you that are interested: that nasty bit of malware that kept copying a spam-url over the clipboard contents is contained within a malicious Flash ad, which appears on a number of major websites. Zero Day has the details, but the gist of it is that a banner is responsible for spamming your clipboard.

Expect more attacks like these; just like with the GIFAR-attack, content publishers and ad publishers will have to implement much stricter checking of uploaded files.
