Bitquery Data Reveals BitMart Lost $391,000 in Recent Security Breach

Key Facts

1BitMart confirmed a security breach on November 2, with investigations suggesting the same group behind the Mercado Bitcoin hack is responsible.

Bitquery data revealed that the recent BitMart security breach resulted in $391,000 being drained across three layer-2 networks. The exchange confirmed the hack occurred on November 2, 2024, with preliminary investigations linking the incident to the same group that targeted Mercado Bitcoin. According to crypto.news, BitMart founder Sheldon Xia acknowledged the breach after blockchain transactions showed funds moving to addresses associated with the Brazilian exchange exploit.

The patterns identified in the BitMart breach suggest a coordinated effort by the entity responsible for stealing over $46 million from Mercado Bitcoin. BitMart continues its restructuring efforts following previous security vulnerabilities, as the latest data confirms the stolen assets were moved via cross-chain protocols.

A revised creditor plan is expected to be released in November 2026 to address the impact of the recent losses. The exchange is currently working to stabilize operations and enhance security measures for its remaining user assets.
