"Stuxnet is a computer worm discovered in June 2010. It targets Siemens industrial software and equipment running Microsoft Windows. While it is not the first time that hackers have targeted industrial 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 initially spreads indiscriminately, but includes a highly specialized malware payload that is designed to target only Siemens supervisory control and data acquisition (SCADA) systems that are configured to control and monitor specific industrial processes. Stuxnet infects PLCs by subverting the Step-7 software application that is used to reprogram these devices.
Different variants of Stuxnet targeted five Iranian organizations, with the probable target widely suspected to be uranium enrichment infrastructure in Iran; Symantec noted in August 2010 that 60% of the infected computers worldwide were in Iran.Siemens stated on 29 November that the worm has not caused any damage to its customers,but the Iran nuclear program, which uses embargoed Siemens equipment procured clandestinely, has been damaged by Stuxnet. Russian computer security firm Kaspersky Lab concluded that the sophisticated attack could only have been conducted "with nation-state support", this was further backed up by the Finnish computer security company F-Secure's chief researcher Mikko Hyppönen who commented in a Stuxnet FAQ, "That's what it would look like, yes". It has been speculated that Israel and the United States may have been involved. . . "
Doesn't sound out of the realm of reality, does it?!
