Bithumb Security Breach Leaves Customer Data Under Review
Bithumb, a cryptocurrency exchange, has confirmed a security breach where unauthorized access to its internal mobile groupware system caused a personal data leak. The exchange is still investigating whether the exposed information includes customer records. The incident follows earlier internal control failures, including a mistake where the exchange mistakenly credited customers with 620,000 Bitcoin, worth over $40 billion, instead of 620,000 won. The Financial Supervisory Service is assessing the breaches at affected institutions, including Daishin Securities, which reported a leak of personal and credit information for 38,490 customers.
