## Summary

Sega says a cyberattack on Japanese email delivery provider Arara exposed email addresses linked to newsletters distributed on Sega’s behalf. Sega accounts used for in-game rewards and other services do not appear to have been affected, but the company is warning newsletter subscribers to watch for phishing attempts.

Sega’s announcement reportedly put the total number of exposed addresses at 2,196,044, of which 92,273 were linked to the affected newsletters. These included event announcements and updates for several arcade rhythm games, as well as Sega Lucky Kuji Online newsletters. Sega said no other personal or payment details, or passwords, were known to have leaked, and there were no reports of misuse at the time of its announcement. Newsletter distribution through Arara has been suspended while the companies investigate, and Sega plans to contact affected subscribers.
