Stuxnet could spread stealthily between computers running Windows-even those not connected to the Internet. (Iran has not confirmed reports that Stuxnet destroyed some of its centrifuges.) The worm's authors could thus spy on the industrial systems and even cause the fast-spinning centrifuges to tear themselves apart, unbeknownst to the human operators at the plant. Finally, it compromised the programmable logic controllers. Then it sought out Siemens Step7 software, which is also Windows-based and used to program industrial control systems that operate equipment, such as centrifuges. First, it targeted Microsoft Windows machines and networks, repeatedly replicating itself. This worm was an unprecedentedly masterful and malicious piece of code that attacked in three phases.

Although a computer virus relies on an unwitting victim to install it, a worm spreads on its own, often over a computer network.

Recognition of such threats exploded in June 2010 with the discovery of Stuxnet, a 500-kilobyte computer worm that infected the software of at least 14 industrial sites in Iran, including a uranium-enrichment plant. headquarters in Woburn, Mass., battling the most insidious digital weapons ever, capable of crippling water supplies, power plants, banks, and the very infrastructure that once seemed invulnerable to attack. As a senior researcher for Kaspersky Lab, a leading computer security firm based in Moscow, Roel Schouwenberg spends his days (and many nights) here at the lab's U.S. This office might seem no different than any other geeky workplace, but in fact it's the front line of a war-a cyberwar, where most battles play out not in remote jungles or deserts but in suburban office parks like this one. A life-size Batman doll stands in the hall. Cryptic flowcharts are scrawled across various whiteboards adorning the walls.
