BitMart Exchange Hacked, $391,000 Drained from Hot Wallets
BitMart exchange experienced a hack on November 2, 2026, resulting in a loss of approximately $391,000. The attack affected hot wallets on Base, Arbitrum, and Optimism.
On November 2, 2026, BitMart exchange was hacked, leading to the draining of around $391,000 from its hot wallets. The incident occurred while the exchange was undergoing restructuring and had a severely understaffed security team. The attackers targeted wallets associated with the exchange on the Base, Arbitrum, and Optimism networks.
The preliminary investigation indicates that the attack may have been executed by the same group responsible for targeting Brazil’s Mercado Bitcoin on the same day. The specific techniques used in the attack have not been detailed, but the simultaneous targeting of multiple exchanges suggests a coordinated effort.
The loss of $391,000 represents a significant incident for BitMart, particularly given the context of its ongoing restructuring. The involvement of multiple blockchain networks complicates the tracing of the funds, as the stolen assets could potentially be moved across different platforms.
No specific addresses have been provided in the description, so the on-chain record details remain unclear. The incident highlights the vulnerabilities that can arise during periods of operational change within exchanges.
