Stuxnet --
Stuxnet is an Computer Worm discovered in the year of June 2010, that is initially spreading via windows machines and targeting the Siemens Systems. it is the first discovered malware that spies on and subverts industrial systems, and the first to include a programmable logic controller (PLC) rootkit.
The worm will spread very fastly and it is mainly target to the Siemens SCADA(supervisory control and data acquisition) Systems that are configured to control and monitor specific industrial processes. It mainly infects the PLC in the SCADA Systems.
when security Expers find to try the sources of the Stuxnet they found that the some sources are in belaraus and the spreading of worm is mostly in Iran i.e..more than 60 % and it mainly infects the iran nuclear program, which uses embargoed Siemens equipment procured secretly, has been damaged by Stuxnet.
The affected countries
Iran - 58.8%
India - 8 %
USA - 1%
The worm itself now appears to have included two major components. One was designed to send Iran’s nuclear centrifuges spinning wildly out of control. Another seems right out of the movies: The computer program also secretly recorded what normal operations at the nuclear plant looked like, then played those readings back to plant operators, like a pre-recorded security tape in a bank heist, so that it would appear that everything was operating normally while the centrifuges were actually tearing themselves apart
About two years ago, centrifuges at Iran’s uranium enrichment facility at Natanz started failing at a suspicious rate. Iran eventually admitted that computer code created problems for their centrifuges, but downplayed any lasting damage. Computer security experts said it was the handiwork of the Stuxnet code, and that it destroyed more than 1,000 centrifuges. Many believe the U.S., in conjunction with Israel, sabotaged the system.
Ralph Langner, a well-respected expert on industrial systems security, published an analysis of the worm, which targets Siemens software systems, and suggested that it may have been used to sabotage Iran's Bushehr nuclear reactor. A Siemens expert, Langner simulated a Siemens industrial network and then analyzed the worm's attack.

on 1 september 2011 security experts found an virus related to the family of stuxnet and they call it as 'DUQU' . it is designed to capture information like keystrokes and system information.
