The U.S. government concluded its "Cyber Storm" wargame Friday, its biggest-ever exercise to test how it would respond to devastating attacks over the Internet from anti-globalization activists, underground hackers and bloggers.
Participants confirmed parts of the worldwide simulation challenged government officials and industry executives to respond to deliberate misinformation campaigns and activist calls by Internet bloggers, online diarists whose "Web logs" include political rantings and musings about current events.
The Internet survived, even against fictional abuses against the world's computers. Experts depicted hackers who shut down electricity in 10 states, failures in vital systems for online banking and retail sales, infected discs mistakenly distributed by commercial software companies and critical flaws discovered in core Internet technology.
Some mock attacks were aimed at causing a "significant cyber disruption" that could seriously damage energy, transportation and health care industries and undermine public confidence, said George Foresman, an undersecretary at the Homeland Security Department.
There was no impact on the real Internet during the weeklong exercise.
Government officials from the United States, Canada, Australia and Britain and executives from Microsoft, Cisco, Verisign and others said they were careful to simulate attacks only using isolated computers, working from basement offices at the Secret Services headquarters in downtown Washington.
The Homeland Security Department promised a full report on results from the exercise by summer, reports AP.
