Virus Infection on Company Computers

Mitsubishi Heavy Industries, Ltd.
On November 27 it came to light that computers used by company employees had been infected with a new type of virus. The infection affected four computers used for performing space systems related tasks at the Nagoya Aerospace Systems Works.

The detected virus is of a kind unknown before, and its properties suggest the possibility that information may have been breached. Immediately after its detection, measures were taken to exterminate the virus and prevent any resulting damage from spreading. An investigation is now under way in cooperation with experts from outside the company to identify how the virus entered the company's computer network and to assess what damage may have occurred, including possible information leakage.

We apologize for any trouble or inconvenience this situation may have caused to our customers and other parties concerned. We will continue the investigation now under way and make every effort to further boost our computer security.
