Chainalysis: Mercado Bitcoin Loses Approximately $49 Million in Attack

Chainalysis reported on November 3 that Brazilian crypto exchange Mercado Bitcoin suffered an attack resulting in an estimated $49 million in stolen crypto assets, spread across 17 blockchains, with the largest shares coming from Bitcoin and Ethereum. Working with the exchange, law enforcement, and industry partners, Chainalysis helped freeze nearly $10 million of the stolen funds and continues to trace the remainder. Mercado Bitcoin has stated the incident involved roughly $38 million in assets, with $11 million frozen, and said users will not suffer losses. The discrepancy between the two figures remains unresolved. Watch for updates on further asset freezes, law enforcement action, and any clarification of the total loss amount.
