The passwords on vBulletin are double hashed, but your contact information is likely exposed.

Most forums give away their software version and often hosting server version. With that information, it's relatively trivial to try well documented exploits.
In this case, this group is targeting Vbulletin (forum software) sites because they know how to hack them. Apparently people running Vbulletin are scrambling to fix it.
I wouldn't take it as something that targets our common interest.

If you have a server up, people are scanning looking for holes 24/7/365.. It's just the nature of our wild west internet.

If the site is hacked, stay away from it...
