Bithumb says it has been hacked through an internal employee system, and it is still assessing whether customer information was exposed. CoinDesk reports the breach affected a system that Bithumb says is separate from its trading platform, while the exchange continues determining the scope of any impact.
Other outlets describe a broader wave of cyber incidents hitting South Korea’s financial sector. Business Line reports that Yonhap says three firms, including Bithumb, have reported data breaches, citing Daishin Securities’ emergency measures. Korea Times adds details that Daishin Securities says personal and credit information of roughly 38,490 customers was leaked, with unauthorized access detected around Oct. 17 on a server tied to online account openings, and it also reports an attack at Mirae Asset Global Investments.
Across the coverage, the common thread is reporting of reported data breaches and ongoing efforts by companies and authorities to determine what information was accessed and how extensively. The most specific confirmed figures relate to Daishin Securities’ reported customer record exposure, while Bithumb’s final breach scope remains under review.
