[Wu Blockchain News] Mercado Bitcoin confirms cyberattack, Hypernative estimates over $40M suspected ...

Mercado Bitcoin confirmed on November 2 that one of its systems suffered a cyberattack, with the Brazilian exchange estimating roughly $38 million in assets involved while blockchain security firm Hypernative preliminarily identified over $40 million in suspicious transfers across at least 10 blockchains including Bitcoin, Ethereum, Solana and Tron. The exchange said the incident was quickly contained, no customer data leaked and customers will not incur losses, though deposits and withdrawals remain temporarily suspended as a precaution. Tether froze more than 4.5 million USDT tied to the incident, and Mercado Bitcoin said it has blocked approximately $11 million working with Tether, Circle, Paxos, BRL1 and Chainalysis while identifying additional assets eligible for blocking. The attack method remains unknown and the loss figure has not been confirmed by the exchange. Customers face no asset losses per the exchange, but no timeline has been announced for resuming services, which will restart once security conditions are fully met.
