Iranian power plant infected by Stuxnet
Found on Ars Technica on Sunday, 26 September 2010
Due to the highly targeted nature of the Stuxnet worm and a large concentration of infections in Iran, analysts speculated that it may have been launched by a major government in an effort to sabotage Iran's controversial Bushehr power plant.
The Stuxnet worm is designed to infect the programmable logic controllers in supervisory control and data acquisition (SCADA) systems that are manufactured by Siemens.
Iran's government has been purging the Stuxnet malware from computers at Bushehr but says that the major systems of the plant haven't been damaged.
Even if the worm had any serious effects, the officals in Iran would never admit it. Remember guys, "everything is ok" as Comical Ali would have said. There is no problem unless you admit it.
