It isn't every day that PLCs and national security are mentioned in the same sentence. Although perhaps they should be. Which is why this segment from CBS's "60 Minutes" on the Stuxnet virus caught my attention. The piece sheds some light on the shadowy world of computer viruses and how software is being used by state military and intelligence agencies to conduct stealth wars by attacking the very unglamorous control infrastructures that are controlled by PLCs.

The piece focuses on the Stuxnet virus and the way it was able to gain access to nuclear material processing plants in Iran and subtly disrupt the centrifuges that were presumably being used to enrich uranium.
