Bithumb Hack: Crypto Exchange Says Employee System Breached, Customer Funds Safe

TLDR Bithumb, South Korea’s second-largest crypto exchange, said an outsider broke into its internal employee mobile system and took personal information. No crypto funds were reported lost, and Bithumb says the system is separate from its trading platform. Daishin Securities said data for 38,490 customers leaked, while Mirae Asset Global Investments said it blocked abnormal access. The Financial Supervisory Service said cyberattacks had hit 16 South Korean financial firms as of Oct. 14. This is Bithumb’s second internal controls problem this year, after a February error that credited customers with 620,000 BTC.
