In the 20th century, this would have been a job for James Bond.The mission: Infiltrate the highly advanced, securely guarded enemy headquarters where scientists in the clutches of an evil master are secretly building a weapon that can destroy the world. Then render that weapon harmless and escape undetected.But in the 21st century, Bond doesnt get the call. Instead, the job is handled by a suave and very sophisticated secret computer worm, a jumble of code called Stuxnet, which in the last year has not only crippled Irans nuclear program but has caused a major rethinking of computer security around the globe.Intelligence agencies, computer security companies and the nuclear industry have been trying to analyze the worm since it was discovered in June by a Belarus-based company that was doing business in Iran. And what theyve all found, says Sean McGurk, the Homeland Security Departments acting director of national cyber security and communications integration, is a “game changer.”
