The Natanz Fuel Enrichment Plant was opened near the city of Natanz, in the Isfahan province of Iran. On opening, 160 centrifuges were operating, with 1000 more under construction.
About 2 years after opening the facility, technicians noticed that several of the centrifuges were spinning faster than they were designed for, and breaking as a result. They contacted cybersecurity experts at Kaspersky, a Belarusian firm.
Over a year later, a worm was discovered lurking on the computers that ran the centrifuges, as well as on other critical infrastructure projects around the world.
On the 30th of July, Eric Chien published a detailed analysis of the worm, naming it “Stuxnet” after binaries found in the codebase.
A few months after the Stuxnet dossier, Iran's top nuclear scientists are the targets of street bombings.
9 months later, a major oil pipeline in Iran explodes.
