The widespread compromise affecting key government agencies is ongoing, according to the U.S. government. During the simulated cyber attack that took place yesterday in Washington, the US are still not ready to deflect or mitigate such an attack to an extent that would not affect the everyday life of its citizens. The entire scenario was thought up by Michael Hayden, the former CIA Director, and the faux attack began with malware masquerading as a free March Madness application for smartphones. Once activated, it spread fast and first incapacitated cellphone networks, then landlines, the Internet, and finally – aided by mock bombs exploding in a couple of gas pipelines and power stations – brought the entire East Coast electrical power grid to its knees.
