Fascinating. This reminds me a of a hacker attack the CIA allegedly pulled on a Soviet gas pipeline way back in 1982.
Stuxnet is a computer worm targeted at industrial equipment that was first discovered in July 2010 by VirusBlokAda, a security firm based in Belarus. While it is not the first time that hackers have targeted industrial systems, it is the first discovered worm that spies on and reprograms industrial systems, and the first to include a programmable logic controller (PLC) rootkit.It was specifically written to attack Supervisory Control And Data Acquisition (SCADA) systems used to control and monitor industrial processes. Stuxnet includes the capability to reprogram the PLCs and hide its changes.
The worm’s probable target is said to have been high value infrastructures in Iran using Siemens control systems. According to news reports the infestation by this worm might have damaged Iran’s nuclear facilities in Natanz and eventually delayed the start up of Iran’s Bushehr Nuclear Power Plant. Although Siemens initially had stated that the worm had not caused any damage, on November 29, Iran confirmed that its nuclear program had indeed been damaged by Stuxnet.
