Stuxnet was about what happened next

US and Israeli intelligence services collaborated to develop a destructive computer worm to sabotage Iran's efforts to make a nuclear bomb, The New York Times reported Sunday.The newspaper quoted intelligence and military experts as saying Israel has tested the effectiveness of the Stuxnet computer worm, which apparently shut down a fifth of Iran's nuclear centrifuges in November and helped delay its ability to make its first nuclear weapons.

Iran’s developing ability to launch cyber attacks will make it “a force to be reckoned with,” the head of the U.S. Air Force Space Command said. General William Shelton said the Iranians are responding to an attack on the computer operating system that runs the uranium enrichment facilities in the country’s suspected nuclear-weapons program.

While the origins of the Stuxnet worm remain obscure, many experts believe it was created by a government with the intent of sabotaging Iran’s nuclear program.

A German computer security expert said Thursday he believes the United States and Israel's Mossad unleashed the malicious Stuxnet worm on Iran's nuclear program."My opinion is that the Mossad is involved," Ralph Langner said while discussing his in-depth Stuxnet analysis at a prestigious TED conference in the Southern California city of Long Beach."But, the leading source is not Israel... There is only one leading source, and that is the United States."

Stuxnet, a worm that infected computers in 155 countries and was used to vandalize an Iranian nuclear site last year, may have struck again.

US security firm Symantec has warned of a new computer virus similar to the malicious Stuxnet worm believed to have preyed on Iran's nuclear program.Symantec said Tuesday that the new virus, dubbed "Duqu" because it creates files with the file name prefix "DQ," is similar to Stuxnet but is designed to gather intelligence for future attacks on industrial control systems."The threat was written by the same authors (or those that have access to the Stuxnet source code) and appears to have been created since the last Stuxnet file was recovered," Symantec said on its website.

A computer virus dubbed the world's "first cyber superweapon" by experts and which may have been designed to attack Iran's nuclear facilities has found a new target -- China.The Stuxnet computer worm has wreaked havoc in China, infecting millions of computers around the country, state media reported this week.Stuxnet is feared by experts around the globe as it can break into computers that control machinery at the heart of industry, allowing an attacker to assume control of critical systems like pumps, motors, alarms and valves.
