TOKYO (majirox news) — Information about defense equipment and nuclear power plants on computers belonging to Mitsubishi Heavy Industries Ltd. on Sept. 19 was transferred overseas, sources close to the case said.
Cyber attackers infected Mitsubishi servers and computers with viruses and were believed to have siphoned off information and added infections through overseas sites.
The Metropolitan Police Department, called in to help by the Japanese conglomeration, suspects espionage may be involved in the cyber attacks.
The Defense Ministry, which issues Mitsubishi with contracts to build submarines and destroyers for Japan’s Maritime Self-Defense Force, asked the company to explain the cyber attacks on Monday.
A security company entrusted with overseeing Mitsubishi’s computer networks said records showed company information had been linked to 14 sites outside of the company. Server registration on at least four of those sites was overseas, in China, Hong Kong, India and the United States. Information was transmitted during the cyber attack on at least 20 different servers.
