The Japanese defense ministry said late on Monday that sensitive data on defense equipment may have been breached as a result of cyberattacks on Mitsubishi Electric Corp, a major supplier of the country's defense and infrastructure systems.
The company has told the ministry that potentially stolen data included requirements for defense equipment that the ministry specified for contract bidders in October 2018, the ministry said in a statement.
The ministry said it was still in the process of investigating the security impact of the potential leak. Mitsubishi Electric did not win the contract in the auction.
