Notice of Attack on Mail Magazine Distribution System

On October 21, 2023, we confirmed a possible attack that exploited a vulnerability of our email newsletter distribution system (system provided by Extra Innovation Inc.).
Therefore, as a countermeasure against vulnerabilities, we are updating our email delivery system to the latest version.
We also investigated through several professional investigation services and found no evidence of the email distribution system being compromised for sending emails or email magazine registration data leaked externally.
We will continue to work on strengthening our IT security.
