Disrupting the Mercado Bitcoin Attack: How Chainalysis Led the Freeze of Nearly $10M in Stolen Funds

Early this morning Mercado Bitcoin, Brazil’s largest crypto exchange, suffered a security incident that resulted in approximately $49 million in stolen funds. As a Chainalysis customer, Mercado Bitcoin alerted our team in the early hours of the incident. We immediately mobilised our global team of investigators to lead the blockchain intelligence response, working closely with Mercado Bitcoin, law enforcement, and industry partners to help freeze nearly $10 million in stolen funds. Chainalysis analysts from three continents logged into our digital war room to discuss the flow of funds and coordinate a response plan.
