I'm posting this here as I am currently at work so can't fix the problem / ammend my site to get the word out and I know we've got a few cross posters from here.
At present, the main information site is still intact and working as it should be our forum has taken a hit. I am hoping it is a simple fix (I have the software to get it sorted) but can't promise the posted information will still be present- its highly likely this hack has deleted our posts / users. I'll keep you posted on that.
If you attempt to access our forum at present, you won't be able to but will instead get a window with some advertisement for the champion who did the damage- its all in a language other than English so I've got no idea what it all means. There will be a pop up window asking for passwords- don't enter anything in there if curiousity does get the better of you and you want to take a look.
I have seen that particular one before. Last time the owner of the particular forum was able to get his IP from the log on the server, and did manage to track him down and reported him.
That was a while ago though, and I dare say he's worked out how to alter the server log, but it's worth a shot. If you're unsure what you're looking for, feel free to PM me the server log and I'll sift through it. I've done a bit of work tracking down 'attacks' on other servers before.
