The Financial Security Institute detected a data leak from its continuous information security assessment system at around 3 p.m. on November 9, blocked access, and reported the incident to the Financial Services Commission (FSC) and the Korea Internet & Security Agency (KISA). An estimated 130 or more files from 48 financial firms were leaked, along with approximately 200 administrative forms, more than 300 personal information entries in those forms, and more than 350 system user information records. The attacker bypassed SMS verification to create an account impersonating the Financial Supervisory Service and exploited inadequate access authorization checks in an operational inspection feature. The institute blocked 246 attacking IP addresses, while the FSC launched an on-site inspection and announced a targeted audit.
