Incident Overview
The attacker used compromised validator hot keys to meet the quorum and drain approximately $24.15 million USDC. The funds were bridged to Ethereum and swapped for ETH. Arbitrum’s native bridge was unaffected, and AFX’s core trading infrastructure remained secure. The team suspended bridge operations and is investigating with security partners.
