pigrabbitbear writes "It's hard to imagine what cyberwarfare actually looks like. Is it like regular warfare, where two sides armed with arsenals of deadly weapons open fire on each other and hope for total destruction? What do they fire instead of bullets? Packets of information? Do people die? Or is it not violent at all — just a bunch of geeks in uniforms playing tricks on each other with sneaky code? Barack Obama would like to clear up this question, thank you very much. In an op-ed published in the Wall Street Journal the president voiced his support for the Cybersecurity Act of 2012 now being considered by the Senate with the help of a truly frightening hypothetical: 'Across the country trains had derailed, including one carrying industrial chemicals that exploded into a toxic cloud,' Obama wrote, describing a nightmare scenario of a cyber attack. 'Water treatment plants in several states had shut down, contaminating drinking water and causing Americans to fall ill.' All because of hackers!"
