InQuuater Co., Ltd. deeply regrets to inform you of a recent security incident involving the cloud-based website platform "Studio," managed by Studio Inc. Unauthorized access to Studio's cloud environment may have led to the exposure of information submitted via our website's inquiry form to third parties. We sincerely apologize for any concern and inconvenience this incident may have caused our valued customers and stakeholders. We are working diligently with Studio to resolve the issue and implement measures to prevent future occurrences. Thank you for your understanding and continued support.

1. Overview and Timeline

According to Studio, unauthorized access exploiting a vulnerability in certain features occurred between September 30 and October 1, 2026 (the period confirmed as of the date of this notice). As a result, data remained accessible from outside Studio's environment until October 14, when Studio addressed the issue.

The vulnerability has since been fixed, and the access path used for the unauthorized access has been blocked.
