Mercado Bitcoin, one of Brazil's largest digital asset exchanges, experienced a significant security incident on Monday that resulted in the loss of approximately $40 million in assets. The company identified and contained a hacker attack that transferred funds from its wallets to the attacker.
In response, Mercado Bitcoin temporarily suspended deposits and withdrawals as a precautionary measure. The exchange stated that despite the incident, no customer funds were affected and no personal data was leaked. The company's swift containment suggests the breach was limited to its operational reserves rather than customer-held assets.
