Mercado Bitcoin Restores Account Viewing After Cyberattack

Mercado Bitcoin began restoring read-only access to customer accounts on November 9, a week after a cyberattack disrupted its services, allowing customers to inspect balances while trading, transfers and withdrawals remained unavailable. The Brazilian cryptocurrency exchange has not announced when withdrawals will resume.

The first recovery phase lets customers view account information recorded on November 2, the day the platform was shut down. The exchange said the displayed balances reflect positions from that date, rather than later activity. In its website view, customers can see holdings by asset and category; its app provides a holdings summary. Transaction services will return in stages after security checks, according to the company.

Mercado Bitcoin said it would replace affected assets with company funds and that customers would not bear losses. The company has not provided a date for restoring withdrawals. It has said a later stage will require customers to reconfirm registration details and set new passwords before moving funds. When withdrawals through Pix resume, the company plans initially to restrict them to accounts in the customer’s own name.
