TOKYO, May 20 (Xinhua) -- Information about a next-generation, high-speed gliding missile may have been accessed by a cyberattack on Mitsubishi Electric Corp., local media cited sources close to the matter as saying on Wednesday.
According to the sources, along with Mitsubishi Electric Corp., Japan's Defense Ministry is also investigating the potential leaking of data regarding the prototype missile's capabilities.
They added that the loss of information includes details about the prototype missile's production that was requested by the defense ministry during the bidding process for the contract to develop the weapon, according to the sources.
While the information on the prototype missile, capable of flying at high speeds but on an irregular trajectory, thus making it hard to be intercepted, was not designated as being classified by the defense ministry, due to changes that could occur during the developmental process, the information was regarded by the ministry as highly sensitive, the sources added.
"The defense ministry is closely examining the impact of the suspected leak of information on security," Japan's top government spokesperson, Chief Cabinet Secretary Yoshise Suga, said at press briefing on the matter, declining to provide specific details.
Mitsubishi Electric was hit by a sizable cyberattack in January, the firm said, and details about the Self-Defense Forces, and personal data on 8,122 individuals, may have been taken during the attack.
NEC Corp. and Kobe Steel Ltd., two major Japanese firms who are also involved in working on defense-related contracts, have also undergone cyberattacks, according to local media reports. Enditem
