Japan’s Major Defense Contractor Attacked by Hackers

Japan has been hit by its first major cyber attack, with perpetrators hacking into Japan’s defense contractor Mitsubishi Heavy.

Mitsubishi Heavy, which is Japan’s biggest defense contractor, informed that the company’s systems had come under attack from hackers. Media reports claim that that the company’s submarine, missile and nuclear power plant divisions had been targeted by the hackers, Reuters notes.

The company, which first discovered the attack on August 11th, announced that it believes that some information might have been stolen by hackers in the cyber attack. This is the perhaps the biggest cyber attack Japan has faced.

"We've found out that some system information such as IP addresses have been leaked and that's creepy enough," said a Mitsubishi Heavy spokesman.

"We can't rule out small possibilities of further information leakage but so far crucial data about our products or technologies have been kept safe," the spokesperson added.

According to a report in Japan’s Yomiuri newspaper, the company discovered around 80 virus infected computer systems, including those affected with Trojan Horses and other information stealing viruses, in its Tokyo based headquarters and research and development facilities elsewhere.
