Well, apparently this has happened before, so I feel there's some hope. Basically, I got hacked, (defaced, I guess, as all the content is intact). I'm hosted on Host Department (not HostGator as many of the other hacked sites). I don't know what to do, although I've already reset my username and password (changed both).
I read a post about someone else also getting hacked/defaced, and made my theme directory unwritable, following a precaution I read.
http://sairah.endless-time.net
That's my site, and as you can see, it's reverted to an UglyFugly signature page for the hackerz. >.< Any and all help would be appreciated. Also, here's a site where my site is listed as having been hacked, along with the party's supposed alias:
http://www.zone-h.org/archive/defacer=Very%20Secret
A few entries down from the top of the list. Direct link to that incident:

I don't know if those links will be of any help to anyone, but I figured just in case.
