Cointelegraph reached out to Bithumb for further comment.

The incident adds to a recent wave of cyberattacks in Korea’s financial sector. Mirae Asset Global Investments said it had blocked abnormal external access to some web systems and was investigating the incident.

The Korea Times reports that asset manager Mirae Asset Global Investments and Daishin Securities were also recent victims of cyberattacks. Daishin Securities said that personal and credit information belonging to 38,490 customers had been leaked.
