Brazil’s largest crypto exchange confirms cyberattack as millions flow out of platform

Brazilian cryptocurrency platform Mercado Bitcoin suspended all deposits and withdrawals after a cybersecurity incident on Monday morning. Blockchain security companies said more than $46 million in assets left the platform late Sunday night, although Mercado Bitcoin did not confirm that figure. The company said the attack did not harm customers or result in a data breach, but several experts disputed this assessment and presented blockchain evidence that attackers siphoned funds from some customer wallets.
