Mercado Bitcoin Hacked, Over $40M in Suspicious Transfers Detected

Brazilian cryptocurrency exchange Mercado Bitcoin confirmed a security incident and suspended deposits and withdrawals on November 2. The company stated it had not been accessed by attackers for any personal information and that customer funds were unaffected.

Blockchain security firm Hypernative identified over $40 million in suspicious transfers linked to Mercado Bitcoin across multiple blockchain networks. The transfers included Bitcoin, Ethereum, Solana, Tron, and other tokens, with the majority occurring between 06:19 and 06:53 UTC on November 2.

Mercado Bitcoin shared five wallet addresses associated with the suspicious transactions, covering Ethereum-compatible networks, Bitcoin, Solana, Stellar, and Tron. The exchange said it provided the information to assist blockchain investigators in tracking the assets.

The incident follows a major security breach at Binance, where about $6.3 billion was stolen. However, the attackers behind the Mercado Bitcoin incident have not been identified. The exchange has not disclosed a confirmed loss figure or provided technical details about the breach.

Mercado Bitcoin continues to monitor the situation and is in communication with authorities. It has not announced a confirmed date for resuming services. The company maintains that customers remain unaffected while investigations into the breach continue.
