Overview of the Incident and Scope of Impact

This is the third report regarding unauthorized access to the system provided to Iwai Cosmo Securities. The cause was a misconfiguration of administrative functions. As an impact, unintended trade orders were executed for some customer accounts but have been restored to their pre-transaction state, and no financial burden has occurred. There is a possibility that personal information (names, email addresses, etc.) of 4,975 customers was leaked; however, account logins and fund transfers are not possible.

Response and Future Reinforcement Measures

We have established an incident response headquarters, inspected external exposure routes, conducted vulnerability assessments and fixes, strengthened login protection, implemented multi-layered defenses, enhanced monitoring systems, standardized reporting criteria and operations, and performed similar inspections and reinforcements for partner systems. Going forward, we will promote internal organizational integration and reinforcement, standardization of monitoring and reporting criteria, and standardization of security levels.
