SEGA Discloses Data Breach Affecting Over 2.19 Million Email Addresses
Sega has confirmed that unauthorized access to its third-party email distribution platform, Arara, resulted in the exposure of more than 2.19 million user email addresses. The company announced this incident on November 9, specifying that the compromised data includes addresses linked to various promotional newsletters for titles such as CHUNITHM Mate, ONGEKI Re:Fresh Act.2, and Maimai DX MAGiCAL.
Sega emphasized that sensitive personal details, including names, birth dates, residential addresses, phone numbers, credit card information, and login passwords, were not accessed or leaked during the breach. Furthermore, users with Sega Accounts remain unaffected because those services utilize a separate communication infrastructure. The company is currently collaborating with Arara to investigate the incident and has advised recipients of the affected newsletters to remain cautious of potential phishing attempts. Sega plans to contact each impacted individual directly once the investigation concludes and will strengthen its external data management protocols.
