Stuxnet, a computer virus that attacked Iran's nuclear program, dates back to 2007, according to researchers at Symantec Corp. Stuxnet, believed to have been created by the US and Israel, was in development as early as 2005.
Businesses, government, and individuals seek better cyber security measures, as cyberattacks mount in the US. One key focus is how to protect 'critical' systems such as power, water, and transportation.
A Saudi energy company has lately confirmed that its computer networks were targeted by a cyberattack. But perhaps more important is the discovery of Gauss, malware believed to be related to the Stuxnet worm that attacked Iran's nuclear centrifuges in 2009.
Stuxnet infected some 130,000 computers worldwide, most of them related to Iran's nuclear fuel enrichment program. It's programmed to shut down just after midnight Sunday, but there likely are other cyber espionage systems out there.
