During the 2006 "Cyber Storm" military online wargame, players had to be disciplined by the referees for attacking the systems that game was running on:
However, the government's files hint at a tantalizing mystery: In the middle of the war game, someone quietly attacked the very computers used to conduct the exercise. Perplexed organizers traced the incident to overzealous players and sent everyone an urgent e-mail marked "IMPORTANT!" reminding them not to probe or attack the game computers.
"Any time you get a group of (information technology) experts together, there's always a desire, 'Let's show them what we can do,'" said George Foresman, a former senior Homeland Security official who oversaw Cyber Storm. "Whether its intent was embarrassment or a prank, we had to temper the enthusiasm of the players."
