I think we could be all set now (crosses fingers)
There is a bug in the version of vBulletin we are running which is a slightly older version. The "hack" was able to happen because I enabled "show template names" in the forum software setup options a few days ago. This option was turned on so I could easily find portions of code so I could add that code to our new software which I have been working on for the past few weeks.
I am told with this option on a hacker can issue a simple web site url with a few added options on the end to cause the havoc we have been having the past two days.
In addition to turning this option off, I have also been sent a new php file for our software which we can put in place IF this happens again.
The good news is that our server the entire time was very secure, no root kits were installed, no one had root access. Checking out
http://www.zone-h.org/en/defacements/filter/filter_defacer=g00ns/ we were very lucky as this hack group has destroyed other sites and servers. This list of their past hacks actually shows how good our security is compaired to other sites.
i consider ourselves VERY lucky, and not only lucky to have been spared the wrath that this group is known for, but also very lucky to have a guy like Larry Rosenman (you know him as LER) who worked like crazy over the past few days restoring our server whenever we were down.
Because of the problems I was going to do the new software upgrade today, however now I am going to keep an eye on the site and see how it goes, if we are redirected again I will apply the PHP patch I was sent.
I am keeping a close eye on this and thank all of you for your patience and understanding.
