The Real Story of Stuxnet

How Kaspersky Lab tracked down the malware that stymied Iran’s nuclear-fuel enrichment program

Computer cables snake across the floor. Cryptic flowcharts are scrawled across various whiteboards adorning the walls. A life-size Batman doll stands in the hall. 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. 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. 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.

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

New Pixel Sensors Bring Their Own Compute

Atomically thin devices that combine sensing and computation also save power

By giving compute powers to atomically thin versions of the CMOS sensors now found in most digital cameras, a prototype sensor array can capture images using thousands to millions of times less power, a new study finds.

CMOS sensors are a kind of active pixel sensor, which combine a light detector with one or more transistors. Although scientists have made steady progress towards more energy-efficient light detectors, the signal conversion and data transmission capabilities of active pixel sensors are currently extremely energy-inefficient, says study co-lead author Akhil Dodda, an electronics engineer who was at Penn State University at University Park in Pennsylvania at the time of the research.

John Bardeen’s Terrific Transistorized Music Box

This simple gadget showed off the magic of the first transistor

This music box demonstrated the portability and responsiveness of the point-contact transistor.

The Spurlock Museum/University of Illinois at Urbana-Champaign

On 16 December 1947, after months of work and refinement, the Bell Labs physicists John Bardeen and Walter Brattain completed their critical experiment proving the effectiveness of the point-contact transistor. Six months later, Bell Labs gave a demonstration to officials from the U.S. military, who chose not to classify the technology because of its potentially broad applications. The following week, news of the transistor was released to the press. The New York Herald Tribune predicted that it would cause a revolution in the electronics industry. It did.
