Although some computers at Iran's Bushehr nuclear reactor were infected
by the Stuxnet worm, none of the facility's crucial control systems were
affected, Iranian officials claimed Sunday.
The news followed Saturday's admission by Iran that Stuxnet had infected
at least 30,000 computers in the country. The worm, which researchers
have dubbed the most sophisticated malware ever, targets Windows PCs
that manage large-scale industrial-control systems in manufacturing and
Those control systems, called SCADA, for "supervisory control and data
acquisition," manage and monitor machinery in power plants, factories,
pipelines and military installations.
"The studies show that few PCs of Bushehr nuclear power plant workers
are infected with the virus," Mahmoud Jafari, the facility's project
manager, told Iran's state-run Islamic Republic News Agency on Sunday.
