Bushiroad has issued an apology regarding the personal data leak incident involving the mobile game "BanG Dream! Girls Band Party!". Due to management negligence by an external vendor responsible for development, the environment storing closed beta registration and customer service inquiry data was illegally accessed by a third party. It is believed that related personal information was obtained, affecting over 13,000 users and related personnel.
Those affected include 10,194 players who signed up for the closed beta test. Potentially leaked data includes registration email addresses, IP addresses at the time of registration, registration dates and times, and device information. In addition, 71 staff members involved in the operation and development of the closed beta test, as well as 5 individuals who filled out the closed beta survey, were also affected.
Additionally, the personal data of 3,034 users who had contacted customer service was affected. Bushiroad stated that the management issues that caused the incident have been corrected, no illegal access outside the relevant environment has been found so far, and no secondary damage has been confirmed.
Moving forward, we will thoroughly review the information security management systems of outsourced vendors and implement preventive measures. The Bushiroad Group will also further strengthen its internal information security and personal data management. If new facts requiring disclosure are discovered during the investigation, official updates will continue to be released.
