Cointime update: MapleStory Universe (MSU) said an unauthorized external party accessed parts of its off-chain server infrastructure, prompting it to place all services into maintenance from 12:43 Beijing time on November 12, 2026. The blockchain and smart contracts were unaffected, and on-chain records and wallets show no assets were transferred or stolen. Attackers obtained records of some users from November 5 onward, including wallet addresses, nicknames, avatars, login history, some email addresses and linked social accounts, plus Builder Center registration data for 328 applications.
