Post cyberattacks, Japan says its defence data possibly breached
Mitsubishi Electric Corp -- a major supplier of the country's defence and infrastructure systems -- has said that potentially stolen data included requirements for defence equipment that the Defence Ministry specified for contract bidders in October 2018.
Sensitive data on Japan's defence equipment may have been breached as a result of cyberattacks on Mitsubishi Electric Corp, a major supplier of the country's defence and infrastructure systems, the Japanese Defence Ministry has said.
The company has told the Ministry that potentially stolen data included requirements for defence 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.
The supplier initially denied the possibility of a breach of sensitive defence and infrastructure data when it first reported on the 200-megabyte cyberattacks by a third party on January 20.
But subsequent checks at the company revealed that the Defence Ministry's information that required special care was included in data potentially stolen by the attacks, Mitsubishi Electric said in a separate statement on Monday.
The company has said it first discovered the cyberattacks in June last year, more than half a year before it disclosed them to the public.
Meanwhile, Japanese companies -- Pasco Corp. and Kobe Steel -- giving services to the country's armed forces, also disclosed a possible data breach that took place in May 2018 and June 2015, followed by a second attempt in August 2016, respectively.
Pasco Corp. is an aerial image surveillance provider and has tie-ups with the Defence Ministry for delivering latest satellite images to monitor the work and progress at various defence bases and other locations.
Kobe Steel manufactures underwater launch tubes for Japanese submarines and provides key submarine spare-parts for the Japan Self-Defence Forces (SDF).
But both firms say that no damage has been done in either of the data breach attempts as no information leakage had been discovered so far.
