News about Mercado Bitcoin

Brazilian crypto exchange Mercado Bitcoin confirmed a security incident in which over $46 million in cryptocurrency was drained from wallets on Monday, and paused deposits and withdrawals, saying customer funds and data were safe. Despite the suspension, addresses linked to the incident kept receiving funds for hours, and security firms said the hack was carried out through standard transfers rather than a smart contract exploit. An initial post-mortem by Certik's Dickson Wu described small ETH transfers from 27,160 addresses and warned that the attacker could also move money out of customer deposit addresses. According to the article, about $6.2 million had been frozen by Tether and Circle, about $20 million had been moved to new wallets, and over $20 million remained in associated addresses, including all 106 BTC. The hack has not been attributed to an organized group and remains under investigation, coming days after Binance reported a $6.3 billion hack.
