This article today from Sophos http://nakedsecurity.sophos.com/2012/10/31/nuclear-security-silence/ isn't anything new, see http://cliffsesportcorner.blogspot.com/2012/10/security-hacking-backdoor-in-computer.html
But this Quote of a Quote [I'm quoting Sophos, quoting Reuters article], illustrates just how messed up Infrastructure Security is, as well as the stupidity:
"In addition, attendees said they were alarmed to learn that because the government has kept a technique it discovered for attacking electricity generation equipment secret for five years, potential targets had not realized they were vulnerable and therefore did not buy hardware needed to protect themselves."
Also might want to look at Basecamp, which is trying to raise public awareness to pressure politicians and business to improve situation http://www.digitalbond.com/tools/basecamp/
A bit technical, but most computer nerds should be able to follow it no problem.
