I've been on one of my wordpress sites http://www.cbsautos.org today only to find that it has been hacked.
The page reads HaCked by mr.qlq amongst other things.
It seems to have affected the whole site, on the news page there's some crazy shell access thing called tryagshell 1.3?
Biggest problem is I have no idea how they have got in, I've only accessed the site from 2 machines, both are clean and have no trojans or spyware.
Has anyone got any ideas of how it could have been compromised?
