there's a real war breaking out now and law enforcement need to gear up too. Guess Norton has the same issues, they don't want anybody to know though.
It is a typical case of hunter being hunted. Then what will happen to ill equipped webmasters like us?
Unless you use a public script or are a popular website you are not at much risk. People are far more likely to hack a website they know is exploitable (google "powered by phpbb v1.0" etc), or they know is popular (alexa rank < 1000 etc).
Got two sites currently in the 300,xxx alexa range and one in 500,xxx range. Public scripts (Wordpress, phpBB and Mihalism Multi Host). Hackable?
