Dark winter

By the time anyone realizes what's happening, it is too late. A dark network of hackers has infiltrated the computers of the U.S. military, unleashing chaos across the globe. U.S. missiles strike the wrong targets. Defense systems fail. Power grids shut down. Within hours, America's enemies move in. Russian tanks plow through northern Europe. Iranian troops invade Iraq. North Korean destroys Seoul and fires missiles at Japan. Phase 1 of ComWar is complete. Enter Jake Mahegan and his team of highly trained operatives. Their mission is to locate the nerve center of ComWar--aka Computer Optimized Warfare--and to shut down the operation through any means necessary.
