I am going to spend the morning crawling our server looking for anything that shouldn't be there

I guess you've checked all the log files (including messages.log as well as the site logs).

You could also look for large files :

find / -size +100k -print -xdev

looks for files over 100k in size in all directories from '/' downwards. If it's videos etc they would tend to be larger files I would guess.

Let us know how you get on ;-)
