South Korea's Financial Security Institute system hacked, approximately 300 pieces of personal information leaked.

November 11 - According to Yonhap News Agency, the Financial Security Institute (FSI), a specialized financial security agency under South Korea's Financial Services Commission, suffered a hacker attack on its information protection routine assessment system, resulting in the leakage of approximately 300 pieces of personal information including names and dates of birth of financial institution employees contained in administrative forms, as well as approximately 350 masked contact details; the attackers infiltrated by frequently changing IP addresses to disguise normal access.

The system has now been emergency shut down and disconnected from the network, and regulators have been notified. Officials confirmed that no sensitive core security data such as financial consumers' personal credit information or system architecture diagrams were leaked; although customer privacy has not been affected for now, the breach of a dedicated core agency responsible for South Korea's financial security monitoring and threat response has triggered widespread industry concerns about the security defenses of the entire sector. Authorities have ordered a comprehensive review and demanded the establishment of a compensation mechanism.
