The report also attributed the breach to a bare-bones team and security understaffing after restructuring, with doxxing, user threats and retaliation by former employees adding pressure. These are claims in the report, not independently verified findings.

For context, DefiLlama lists Mercado Bitcoin’s November 2 incident at $40 million, with the technique unknown; it does not list this reported BitMart event. The sources do not independently confirm BitMart’s breach details or establish that the two attacks had the same perpetrators. DefiLlama hack registry
