Mercado Bitcoin wallets keep moving funds after $46M hack

Mercado Bitcoin, a major Brazilian exchange, suffered a $46 million cryptocurrency hack on Monday with attackers draining wallets across multiple chains including Base, Optimism, and Arbitrum. Despite the company suspending deposits and withdrawals, funds continued moving from compromised addresses for hours, with $6.2 million frozen by stablecoin issuers and $20 million transferred to new wallets. The exchange claims customers suffered no losses and no data was leaked, but the incident remains under investigation and unattributed to any organized group.
