@LeonidS My site had several files changed / added / replaced during the time the unacms.com site was down.

.htacces
f7z8f78zf7z8fz536ff495.php
index.php
style.php

It looks like malware with payload for attacking a wordpress site. The reason that I was tipped off to this is that my site was only displaying a blank page where the front page should be. I am now in the process of restoring database and files from prior to this incident.
