Bithumb hack exposes staff data as regulators raid exchange
South Korean exchange Bithumb suffered a hack that exposed staff data, and financial regulators have raided the company as part of the investigation. The FSC said it is still checking whether customer data was exposed and is examining the staff-support system while planning stronger safeguards. Traders should watch for confirmation of any customer-data leak, since a breach at a major Korean exchange could weigh on confidence in local trading venues and invite tighter oversight.
