"A web worm that identifies potential victims by searching Google is spreading among online bulletin boards using a vulnerable version of the program phpBB, security professionals said on Tuesday. Almost 40,000 sites may have already been infected. In an odd twist if you use Microsoft's Search engine to scan for the phrase 'NeverEverNoSanity'-- part of the defacement text that the Santy worm uses to replace files on infected Web sites--returns nearly 39,000 hits."
