Is this the incident? https://www.securityfocus.com/news/6767 https://www.securityfocus.com/news/6767 'The Slammer worm penetrated a private computer network at Ohio's Davis-Besse nuclear power plant in January and disabled a safety monitoring system for nearly five hours, despite a belief by plant personnel that the network was protected by a firewall, SecurityFocus has learned. The breach did not pose a safety hazard. The troubled plant had been offline since February, 2002, when workers discovered a 6-by-5-inch hole in the plant's reactor head. Moreover, the monitoring system, called a Safety Parameter Display System, had a redundant analog backup that was unaffected by the worm. But at least one expert says the case illustrates a growing cybersecurity problem in the nuclear power industry, where interconnection between plant and corporate networks is becoming more common, and is permitted by federal safety regulations.' Sounds like the plant was being operated by a skeleton crew since it was mostly disabled.
