Cyber assaults were programs attacking data and other programs. Because much of our world is part of the Internet of Things, more things, more physical things, are now the targets of the attacks. Stuxnet destroyed nuclear centrifuges. An assault in Germany damaged a blast furnace. War is always an arms race between better offenses and better defenses. The offenses have the advantage, for now.
