Scott I know you probably don't want to hear this, but a couple of years ago my forum got hacked and it turned out that they got the login info from a key logger on my Windowz computer that I finally found with some anti-rootkit software. That rootkit went right by the Symantec Corporate antivirus like it wasn't even there! I was lucky in that nothing was destroyed but it could have been ugly. So if you and your Admin Team are using Windows computers to work on the site, then I'd be looking real hard to see if any of them are infected!
After my episode I made a decision to learn to use Linux for anything that has to be secure because Linux seems to be more secure than Windowz I guess simply because the hackers usually go after the largest target, which is Internet Explorer. So if you're not using Linux already, then I'd be looking to make that move some time in the very near future and if you do, then I suggest look at Ubuntu 12.04 LTS with the Mate Desktop addon.
