Through the past few weeks WordPress blogs on hosting services including Dreamhost, GoDaddy, and BlueHost have come under attack. The hack injects the files for your blog and redirects users to another site with malicious content.
If you find the words “zettapetta” anywhere in your site’s code, BEWARE. You’re site has been infected! Contact your host ASAP and ask them to either clean the infection, or restore a backup. If your hosted on one of these services and your site HASN’T been infected, now would be an excellent time to back up!
