Bithumb, a South Korean cryptocurrency exchange, has disclosed a cyberattack on its employee communications system, raising concerns about potential customer data exposure. The attack transpired on Tuesday, with the exchange identifying the breach on Wednesday and notifying regulatory authorities. The compromised system operates autonomously from Bithumb's cryptocurrency trading platform, preventing direct access to customers' digital assets.
Preliminary investigations suggest that the affected information primarily pertains to employees, though Bithumb is scrutinizing whether customer details, inadvertently shared through internal communications, were also compromised. The exchange has alerted the Korea Internet and Security Agency and the Personal Information Protection Commission regarding the incident.
Bithumb has communicated the event to its employees and is evaluating the necessity of further notifications or protective measures if customer information is confirmed to have been accessed. The intrusion method, the categories of data exposed, and the count of potentially affected individuals are under investigation. The identity of the perpetrators and the precise technique employed to breach the system remain unconfirmed.
Bithumb has not disclosed a definitive count of affected individuals or the complete scope of obtained information. The incident unfolds concurrently with separate security breaches at Daishin Securities and Mirae Asset Global Investments. Daishin Securities revealed that hackers accessed personal and financial data of 38,490 customers on October 17, notifying affected clients and cooperating with authorities.
Mirae Asset Global Investments reported unauthorized external access within its web infrastructure, with exposed information limited to certain internal administrative systems and not including sensitive personal or investor data. Financial regulators are examining the incidents, with Governor Lee Chan-jin of the Financial Supervisory Service noting that 16 financial institutions had experienced cyberattacks by October 14, underscoring the growing cybersecurity challenges faced by the sector.
