[MapleStory Universe Off-Chain Servers Hacked, Some User Data Leaked] On November 13th, MapleStory Universe officially announced that on November 12th, the project discovered unauthorized access to some of its off-chain server infrastructure and initiated maintenance on all services starting at 12:43 PM. Preliminary investigations indicate that the blockchain and smart contracts were unaffected, and no assets were found to have been transferred or stolen. The wallet addresses, login IPs, device information, and some email addresses of some users were accessed.

The operating keys will be replaced before service is restored. The investigation is ongoing.
