We had a spammer hack in through apache on a redhat box a month ago. He got in through a clients installed/used phpBB board (of course). The spammer installed shv5 and proceeded to send out millions of emails, of which our courier server promptly rejected doing so, so no harm was REALLY done. Took a while to get rid of the files, as we had to backtrack through the install process of shv5. We canned all our clients use of phpBB and the machine has been clean since. Just our experiences, maybe of some help to you. -Randall Shaw
