The exchange's security notice declined to name an attack vector, and hours later its chief executive said the attacker spoofed transaction data through a compromised backend system, ruling out private key theft.

The second-largest crypto exchange by volume says its internal controls caught a batch-transaction exploit modelled on the techniques that took down Mt. Gox, preventing what would have been one of the largest attempted thefts from a centralised venue.
