If you run a vBulletin forum, versions 4 - 5, you may want to consider downloading your DB if you haven't done it recently. Something to consider, DefCon took down their forum [forum.defcon.org] and left a note:
We have disabled the forums until there is resolution on a possible vulnerability.
For some details about we at DEF CON have decided to close the forums, you can check this story out: [thehackernews.com...]
Once we have a fix/patch installed, we'll re-open service.
