Bithumb Says Hack Leaked Hundreds of Customer Accounts as Cyberattack Wave Hits Korean Finance

Summary
Bithumb said personal information from hundreds of customer accounts was exposed in a recent hack, revising its earlier position that only employee data had been breached.
The disclosure ties the exchange more directly to a broader wave of cyberattacks on South Korean financial firms that also hit Daishin Securities and Mirae Asset.
Daishin previously said 38,490 customers' names, emails and phone numbers were exposed, while Bithumb and Mirae had initially reported incidents without confirming customer data theft.
The attacks follow a September campaign linked to a suspected China-based hacker using an AI tool, prompting South Korea's financial regulator to press institutions to strengthen cybersecurity.
