The group that hacked into Fujitsu’s data sharing tool, which connects government agencies, looked for information on the Tokyo Olympics and nuclear plants, the Asahi Shimbun has learned from multiple government sources. 


The hacking of Fujitsu’s ProjectWEB came to light in May. A total of seven government agencies and outside organizations were affected, including the Ministry of Land, Infrastructure, Transport and Tourism, the Ministry of Foreign Affairs, and the National Information Security Center.


According to government sources, the hackers left trails suggesting that they were interested in such key words as “Olympics” and “nuclear power plant.” The method used for the hacking suggests the involvement of a Chinese hacker group, likely backed by the Chinese government. The group may have attempted to access confidential government information and enter critical infrastructure.


Chinese hackers’ involvement suspected


The Asahi Shimbun and experts studied the incidents to identify the hacker group using the IP address used for the illegal access. The investigation revealed that part of the originating IP address was the same as the one used by Chinese group BlackTech in the past. BlackTech is reportedly backed by the Chinese government. “We cannot be certain, but the group’s high-level expertise and its targeting of government organizations and critical infrastructure strongly suggest it was BlackTech,” a government official said.
