The two-day "cyberwar" simulation involved 230 government agencies, private companies and other groups.

It ran through what would happen if overseas hackers launched massive attacks during a national crisis — as happened in Estonia last year during a wave of ethnic violence, and again in Georgia during the brief Russian invasion this August.
