MapleStory Universe Confirms Data Breach on November 12, User Assets Remain Safe

According to MapleStory Universe (MSU), the gaming platform confirmed an external unauthorized access to part of its off-chain server infrastructure on November 12 at 12:43 (Beijing time). User data from November 5 onward was compromised, including wallet addresses, usernames, avatars, login history, partial email addresses, linked social accounts, OpenAPI usage records, and transaction activity. However, blockchain and smart contracts were not affected, and on-chain records confirmed no asset transfers or theft occurred. User wallet private keys were never uploaded to MSU systems.

Additionally, 328 applications registered on the Builder Center had their information accessed, but the exposed API keys pose no threat to assets. MSU has cut off the attack pathway, revoked compromised credentials, and is replacing affected servers before service restoration.
