February 2026 Security Issues Related to the Korean & Global Financial Sector

**Executive Summary:** This report documents active and high-risk cyber threats targeting financial institutions — reporting malware and phishing campaigns, sale of administrator firewall/network access on BreachForums enabling potential RCE and full network takeover, a claimed large-scale mortgage application data leak with PII exposure, and ransomware leak-site activity (e.g., Qilin, CL0P), all of which increase risks of data theft, identity fraud, ransomware extortion, and supply-chain compromise.
