There was a period of time over the weekend where the hack was present on the site while we were investigating matters further.
We have now completed our investigation, and have closed all security vulnerabilities after a very thorough investigation.
We have also taken a wide variety of steps to eliminate the possibility of similar attacks in the future.
As one important example, we have made it impossible for anyone including GPWA admin users to access the GPWA vbulletin control panel unless they are accessing it from within our internal network. Normally vBulletin allows any admin user to access the vBulletin control panel.
