Offices of multiple Japanese agencies were breached via Fujitsu's "ProjectWEB" information sharing tool.
Fujitsu also said that attackers had gained unauthorized access to projects that used ProjectWEB, and stolen proprietary data.
Japanese press reported Narita International Airport, located near Tokyo, was impacted as well since Fujitsu attackers managed to steal air traffic control data, flight schedules, and information on business operations.
Cabinet Secretariat's national cybersecurity center issued multiple advisories [1, 2] alerting government agencies and critical infrastructure organizations using Fujitsu's tool to check for signs of unauthorized access and information leakage.
"Fujitsu is currently conducting a thorough review of this incident, and we are in close consultation with the Japanese authorities. As a precautionary measure, we have suspended [the] use of this tool, and we have informed any potentially impacted customers," a Fujitsu spokesperson told BleepingComputer.
