MapleStory Universe Says User Data Exposed, No Assets Lost
MapleStory Universe placed all services under maintenance at 12:43 p.m. (UTC+8) on November 12, 2026, after detecting unauthorized external access to part of its off-chain server infrastructure. According to Odaily, a preliminary investigation found that the blockchain and smart contracts were unaffected; on-chain records and wallets showed no assets had been transferred or stolen, and wallet private keys had never been uploaded to MapleStory Universe’s systems. The attacker obtained some user records dated after 7:26 a.m. on November 5, including wallet addresses, nicknames, avatars, login histories, some email addresses, linked social account information, OpenAPI usage records, and transaction and service activity records. The exposed data did not include real names, phone numbers, physical addresses, KYC information, or payment card details.
