CMS Security Concerns
 

I have noticed a HUGE spike in Google searches for:

"icon legend" "contains no unread posts" "quick navigation" +pools

and

"icon legend" "contains no unread posts" "quick navigation" +targets


which returns, you guessed it, vBulletin 4 sites. This is almost ALWAYS due to a zero day exploit hitting the wire and the little script kiddies taking advantage of it. I have no idea what this could be, but it doesn't look good.
