According to Flybit, a South Korean virtual asset exchange, personal information of 40 customers was leaked on November 5 through unauthorized external access to its internal groupware system operated by Dow Technology. The exposed data includes customer names, resident registration numbers or birth dates, contact information, and in some cases, tax-related details and corporate registration numbers. The exchange discovered the breach after receiving notification from an unauthorized third party and confirmed the incident through its groupware operator.
Flybit stated that its internal systems were not compromised and customer assets remain secure. The exchange has blocked access pathways to the affected system, restricted all overseas IP addresses, and filed a report with the National Police Agency's Cybercrime Investigation Division.
