Security firms are warning that new variants of the Santy worm have start spreading through other search engines than Google. The new versions now also use AOL and Yahoo.
The Santy problem originally flared up a week ago as bulletin board Web sites found their pages erased and defaced by the worm's own text. The worm spread by targeting pages that used vulnerable versions of the PHP Bulletin Board (phpBB) software, and used Google to locate those pages.
Perl.Santy.B is written in Perl script and it attackts vulnerable phpBB 2.x forums. Just like the original Santy it uses search engines to find exploitable forums.
