Mercado Bitcoin Hack: $40M Loss

Mercado Bitcoin Hack: A $40 Million Loss

Mercado Bitcoin, Brazil's largest crypto exchange, has announced that its customers will not bear the cost of a hack that hit its systems on November 2. The exchange has estimated the loss to be around $38 million, although other estimates vary, with Hypernative reporting over $40 million, Arkham at least $46 million, and Chainalysis about $49 million.

The exchange spotted a breach early on November 2 and froze deposits and withdrawals as a precautionary measure. In a statement on X, Mercado Bitcoin said, "We identified and quickly contained a security incident in one of our systems early this morning. As a preventive protection measure, deposits and withdrawals are temporarily suspended."

No Customer Lost Money, No Data Leaked

Mercado Bitcoin has assured its customers that no one lost money and no data was leaked during the hack. However, the exchange has not disclosed how the attackers gained access to its systems.

The security firm Hypernative has flagged more than $40 million in suspicious transfers across at least 10 blockchains, including Bitcoin, Ethereum, Solana, and Tron. Other estimates of the loss include $46 million by Arkham and $49 million by Chainalysis, with nearly $10 million frozen.

Exchange's Response to the Hack

Mercado Bitcoin has blocked $11 million of the stolen assets, with the help of the crypto community and strategic partners, including Tether, Circle, Paxos, BRL1, and Chainalysis. Tether, which issues the USDT stablecoin, has frozen more than $4.5 million in USDT tied to the incident.

The exchange has promised to cover the losses, with CEO stating that the value of the assets involved is about $38 million. However, this amount may not include the frozen assets, which are valued at around $10 million.

Comparison to Binance Hack

The hack on Mercado Bitcoin comes just days after a $6 billion theft at Binance, the world's biggest exchange, which was blamed on North Korea's TraderTraitor group by the FBI. Binance has also pledged to absorb the financial impact of the stolen funds, with CEO Richard Teng stating that about 95% of the affected assets had been replenished.

Implications of the Hack

The hack on Mercado Bitcoin highlights the risks associated with crypto exchanges and the importance of security measures. The exchange's promise to cover losses is only as good as the money behind it, and exchanges are not required to show customers their financial books.

• The hack resulted in a loss of around $40 million.
