Iran Mitigates New Stuxnet-Style Attack

A new Stuxnet-style computer virus attacks an electric utility company in southern Iran, but Iranian officials claim to have successfully contained and mitigated any major damage. This attack came in the wake of the Stuxnet worm that was made public by Tehran in 2010, and crippled a portion of the Iranian uranium enrichment infrastructure. That worm caused damaging speed variances and interruptions in the spinning centrifuges used in uranium enrichment facilities. Undetected before causing this damage, it spread surreptitiously over networks and via flash drives and other removable storage devices.
