Defense data may have been stolen in cyberattack on Mitsubishi Electric Corp: Japan Defense Ministry

In a statement, Japan’s defense ministry stated, a cyber attack on Mitsubishi Electric Corp, a major supplier of the country’s defense and infrastructure systems, has led to a breach of sensitive data on defense equipment.

The potentially stolen data included requirements for defense equipment that Japan’s Defense ministry specified for contract bidders in October 2018, said the ministry in a statement.

The Defense Ministry is still in the process of investigating the security impact of the hack.

Mitsubishi Electric did not win the contract in the auction.

On January 20, 2020, Mitsubishi Electric had initially denied the possibility of a breach of sensitive defense and infrastructure data when it first reported on the 200-megabyte cyberattacks.

“Subsequent checks at the company revealed that the defense ministry’s information that required special care was included in data potentially stolen by the attacks”, said Mitsubishi Electric in a separate statement.

Mitsubishi Electric stated, it first discovered the cyberattacks in June 2019, more than half a year before it disclosed them to the public.
