Sigh..
I'd be cracking it at the hosting provider if they didn't keep daily backups and had them stored off-site. Seriously, it's not that hard. Even if they just backed up the database of the board alone it wouldn't be that bad. They could do it themselves once a week and they'd be better off than they are now.
Brute force attack? or someone just forgot to update vBulletin and left themselves open to some exploit... <a href=

Maybe they'll think about a better backup plan now (insert rolleyes smiley here).
Edit: Oh, and while you can't guarantee people aren't going to attack this forum, the chances are greatly reduced by the fact that it's a custom built board. Essentially it means that people looking to take advantage of exploits on the common systems (vBulletin, Invision, phpBB, etc.) won't have any luck here. It's
always a good idea to do regular backups anyway, no matter how secure the system might be.
What do you do in IT, littlebear?
