The Ashai Shimbun claims that when Mitsubishi Heavy Industries was hit by an attack earlier this year sensitive data and plans were also stolen from the company's network.
The news report claims that sources told it that an investigation had discovered information about fighter jets, helicopters and nuclear power plant design and safety plans, could have been stolen following a malware infection. According to reports, checks on Mitsubishi Heavy computers have uncovered evidence that information was transmitted via them to parties unknown.
TOKYO (Kyodo) -- Information about military aircraft and nuclear power plants linked to Mitsubishi Heavy Industries Ltd. may have been read by outsiders who gained access to the major defense contractor's computer system in recent cyberattacks, government sources said Monday.

TOKYO (Kyodo) -- Information about military aircraft and nuclear power plants linked to Mitsubishi Heavy Industries Ltd. may have been read by outsiders who gained access to the major defense contractor's computer system in recent cyberattacks, government sources said Monday.
Data on the company's fighter aircraft development were transferred from one server to another due probably to computer viruses, Defense Ministry sources said. But it has not been confirmed so far whether the data were transmitted outside the company, the sources said.
The ministry believes the data do not pertain to any confidential national security matters, the Defense Ministry sources also said.
Separately, sources at the Ministry of Economy, Trade and Industry said data pertaining to nuclear reactors may also have been transferred between company servers. But the sources said there is little chance that confidential nuclear reactor data have been leaked.
Mitsubishi Heavy Industries previously reported its computer network had come under cyberattack and 45 servers and 38 computers had been infected with over 50 types of viruses at 11 locations in Japan, including the company's plant in Aichi Prefecture that builds missiles and aircraft engines.
Among the viruses was a type known as a "Trojan horse," which can order data to be transmitted outside.
Some of the affected servers and computers had been forcibly connected to websites abroad, resulting in a loss of some data including Internet Protocol addresses, Mitsubishi Heavy said.
The company has given assurances about the safety of its information on defense-related products and technology, saying the data have been tightly guarded.
