National Police Agency Issues Advisory Following Unauthorized Access-Related Leaks

The National Police Agency states that it "is issuing advisories in light of incidents involving information leaks due to unauthorized access," and has posted links to advisories and response guidance published by related organizations. The posted materials include publicity from the Cyber Police Bureau (R8 Vol.19) and advisory documents from relevant ministries.

Specifically, the Personal Information Protection Commission, 国家サイバー統括室, the Ministry of Internal Affairs and Communications, the Ministry of Economy, Trade and Industry, and the Financial Services Agency have each published responses and points of caution based on unauthorized access and large-scale information leak incidents, and the National Police Agency's page directs readers to these references. The linked documents are expected to outline steps such as confirming the scope of impact, measures to prevent further damage, and notifications or reporting procedures to users.

This advisory does not list specific company names or numbers of affected cases; rather, it urges readers to consult the published materials from the relevant agencies to verify countermeasures. Organizations are recommended to individually review the documents from the applicable ministries and to reassess their own defenses and response procedures.
