Results of investigation

The investigation was conducted with the cooperation of the relevant entities, obtained through submitting notification about the matter to them. These entities included the system developer, the Tokyo Metropolitan Police Department (TMPD), the Security Center of the Information-technology Promotion Agency, Japan (IPA), and the Japan Computer Emergency Response Team Coordination Center (JPCERT). As a result, we uncovered the full details about the unauthorized access into CROSS-EX, but we verified that no secondary damage had been incurred to the customer who have accessed to CROSS-EX. However, we also concluded that it was not possible to identify the all information that had leaked out as a result of the unauthorized access (please refer to the appendix for details). As of the current point in time, we have not received any reports from our customers pertaining to damages arising as a result of this incident.

We are deeply sorry for the inconvenience regarding this matter.
