For anyone interested, CNBC recently produced a "special" called "Code Wars: America's Cyber Threat"[1], which talks about cyber attacks against American interests.
In my opinion, the show was technically weak and seemed more concerned pushing fear-uncertainty-doubt than factual information (on actual cyber attacks against American interests). For example, the show referenced the "Northeast Blackout of 2003" as an example of the potential damage hacking an energy utility could do ... except, as the show quickly (and a little more quietly) pointed out, the event was caused by mechanical failure.
Overall, cyber attacks are a concern, but not necessarily more so than other threats and certainly not as great as some would like you to believe.
