Over $40M in suspicious transfers flagged after Mercado Bitcoin cyberattack

A cyberattack on Mercado Bitcoin prompted a temporary suspension of deposits and withdrawals after the exchange confirmed on November 2, 2026, that one of its systems had been hit. Mercado Bitcoin said it had quickly contained the incident and that customers would not incur losses.

The exchange also said no customer data had leaked. It described the pause in deposits and withdrawals as a precaution, while blockchain security firm Hypernative identified substantial suspicious transfers in its preliminary analysis.

Mercado Bitcoin cyberattack: suspicious transfers exceed $40 million

Hypernative identified more than $40 million in suspicious transfers across at least 10 blockchains. The networks included Bitcoin, Ethereum, Solana and Tron. Its findings describe the scale of suspicious activity rather than a loss figure confirmed by the exchange.

Mercado Bitcoin has not confirmed the estimated losses. The distinction separates Hypernative’s preliminary transfer analysis from the exchange’s statements about the impact on customers: the suspicious-transfer total is not a confirmed customer-loss amount.

For customers, the reported operational effect of the Mercado Bitcoin cyberattack is the temporary suspension of deposits and withdrawals. That precautionary restriction sits alongside the exchange’s assurance that customers would not bear losses and its statement that the incident did not expose customer data.
