Symantec discovers 2005 US computer virus attack on Iran nuclear plants
Internet security firm finds early 'Stuxnet O.5' version revealing espionage and sabotage virus released under George W.Bush - Researchers at the security company Symantec have discovered an early version of the "Stuxnet" computer virus that was used to attack nuclear reprocessing plants in Iran, in what they say is a "missing link" dating back to 2005. The discovery means that the US and Israel...were working on the virus scheme long before it came to public notice -- and that development of Stuxnet, and its forerunner, began under the presidency of George W Bush, rather than being a scheme hatched during Barack Obama's first term. The older version of the virus, dubbed "Stuxnet 0.5" -- to distinguish it from the "1.0" version -- also targeted control systems in Iran's Natanz enrichment facility, the researchers said.
