Sensitive information concerning vital defense equipment, such as fighter jets, as well as nuclear power plant design and safety plans, apparently was stolen from Mitsubishi Heavy Industries Ltd. computers during a cyber-attack in August, sources said.
An internal investigation found signs that the information had been transmitted outside the company’s computer network, with the strong possibility that an outsider was involved.
This is the first time that sources have acknowledged that defense and nuclear plant information may have leaked from Mitsubishi Heavy’s computers due to a computer virus, despite the company saying it had taken appropriate safeguard measures.
The computers were found to have been hacked in August, and 83 computers were found to have been infected with a virus. Those computers were spread out over 11 locations, including the Kobe and Nagasaki shipyards that construct submarines and destroyers as well as the Nagoya facility that is in charge of manufacturing a guided missile system.
