Hackers hit Japan’s Mitsubishi Heavy Industries
Mitsubishi Heavy Industries in Japan has come under cyber-attack. The defence contractor said they discovered the hack on 11th August.

Hackers have hit the computers of Japan's biggest defence contractor, Mitsubishi Heavy Industries Ltd, according to Reuters.

Newspapers in Japan have reported that the company's submarine, missile and nuclear power plant component factories had been targeted.

Mitsubishi Heavy Industries said in a statement that some information may have been stolen during the hack.

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

The company first noticed the hack on 11th August.

The Yomiuri newspaper in Japan reported that approximately 80 virus-infected computers were found at the Mitsubishi Heavy Industries' Tokyo headquarters as well as manufacturing and research and development sites, including Kobe Shipyard & Machinery Works, Nagasaki Shipyard & Machinery Works and Nagoya Guidance & Propulsion System Works.

The Kobe Shipyard builds submarines and makes components to build nuclear power stations, the Nagasaki Shipyard makes escort ships, and the Nagoya plant makes guided missiles and rocket engines, according to the Japanese newspaper.

Mitsubishi Heavy Industries is Japan's biggest defence contractor, winning 215 deals worth $3.4 billion from Japan's Ministry of Defence in the year to last March.
