Bithumb says the breach involving mobile DaouOffice groupware exposed information concerning 6,444 customers and 715 employees, or 7,159 people in total. Among customers, 5,600 were included in encrypted files, while 844 had sensitive materials such as identification documents, driver’s licenses or account information directly exposed. These figures provide a material update to the earlier investigation. The company distinguishes the incident from direct compromise of its core exchange systems or customer assets. Nevertheless, impersonation and follow-on phishing using identity-document copies remain separate concerns, and affected users should verify instructions through official channels.
