Brazilian exchange Mercado Bitcoin has restored read-only access to accounts a week after suffering a $49 million attack. Users can view their balances up to November 2nd, the day the attack occurred, but withdrawals are currently unavailable. The exchange has not announced when withdrawals will be restored. Mercado Bitcoin, with 4.8 million customers, will cover all losses with company funds, but has not yet explained how the attackers gained access to the wallets. Once withdrawals are restored, they will only be processed through Pix, requiring users to reconfirm their information, and withdrawals can only be made to accounts registered in their own name.
