An attacker stole authentication credentials for Wemix's Nile NFT platform service monitoring system and used them to gain access to the Play Bridge Vault. The attacker executed 13 successful withdrawals over two months of preparation, extracting 8.65 million WEMIX tokens and selling them on external exchanges. Wemix delayed disclosure by one week citing precautionary measures.

According to Yonhap News Agency, Kim Seok-hwan, a representative of Wemix Foundation, a blockchain subsidiary of Wemade, admitted at an emergency meeting that they lost approximately 8.65 million WEMIX tokens (worth about $6.22 million) due to a hack. On February 28, the hacker stole the authentication key of the NFT platform "Nile" and attacked the Play Bridge Vault system.
