Stuxnet Was Designed To Subtly Interfere With Uranium Enrichment

ceswiedler writes "Wired is reporting that the Stuxnet worm was apparently designed to subtly interfere with uranium enrichment by periodically speeding or slowing specific frequency converter drives spinning between 807Hz and 1210Hz. The goal was not to cause a major malfunction (which would be quickly noticed), but rather to degrade the quality of the enriched uranium to the point where much of it wouldn't be useful in atomic weapons. Statistics from 2009 show that the number of enriched centrifuges operational in Iran mysteriously declined from about 4,700 to about 3,900 at around the time the worm was spreading in Iran."
