JAEA: unauthorized access to the JRR-3 research reactor support site

On 25 September, the Japan Atomic Energy Agency found that 2,419 files had been downloaded without authorization from JRR-3 RING, the support site for outside users of its JRR-3 research reactor, and blocked outside access. 367 files (175 people) contained personal data: 200 images of photo ID such as driving licences and My Number cards (6 with My Numbers), 146 special health check results for radiation work and 21 radiation worker certificates. According to the Yomiuri Shimbun, an ID with no usage history was apparently created and used.
