Bybit
Security incident.

What the evidence shows.

The February 2025 exchange attack exposed the risk of multi-step transaction approval and wallet operations. The FBI characterized the activity as TraderTraitor and urged blockchain service providers to trace and block the resulting flows.

What the number means.

Reported gross theft at the time. This is not an estimate of Bybit's net balance-sheet loss after any reimbursement or recovery.

How to test resilience.

Secure wallet transaction approvals, independent verification, compromised workflow detection and operational segregation.
