Disrupting the Mercado Bitcoin Attack: How Chainalysis Led the Freeze of Nearly $10M in Stolen Funds
Chainalysis describes its response to the 2 November 2026 hack of Mercado Bitcoin, Brazil's largest crypto exchange, where an attacker drained about $49 million across 17 blockchains. Investigators traced the funds, contacted law enforcement within 30 minutes and worked with Paxos, Anchorage Digital, Ripple, Circle and Tether. Tether froze over $9 million in USDT, nearly $10 million in all. The post does not explain how the attacker got in.
