In two separate incidents, a nuclear power plant and a nuclear lab were targeted for cyber attacks. Director Yukiya Amano from the IAEA disclosed that a nuclear power generation facility came under cyber attack within the last few years. He declined to state which specific nuclear facility was involved. Mr. Amano advised that “This issue of cyber attacks on nuclear-related facilities or activities should be taken very seriously. We never know if we know everything or if it’s the tip of the iceberg.”
In a separate incident, a nuclear lab in the University of Toyama in Japan conducting research on tritium (used in nuclear power plants), also came under cyber attack earlier this year. The attacker appears to have been able to exfiltrate large large amounts of data, some of which was related to the Fukushima clean-up. It is unclear who is responsible for this attack.
