Executive Summary
AI-generated
On November 2, 2026, the largest crypto exchange in Brazil, Mercado Bitcoin, confirmed a cyberattack that resulted in millions of dollars flowing out of the platform. Hackers from North Korea, blamed by the FBI and U.S. Secret Service, siphoned billions from crypto platforms this year. Approximately $46 million was stolen from Mercado Bitcoin late on Sunday night, with some funds frozen at other platforms worth an additional $6.5 million. The attack did not harm customers or lead to a data breach, according to the company's statements; however, blockchain evidence suggests that hackers were able to siphon funds from some customer wallets. With about 4.5 million customers and operating in Latin America (LATAM), Mercado Bitcoin is one of several cryptocurrency exchanges targeted by cyberattacks over the last six months, resulting in losses exceeding $100 million.
