History

Historical Context

The 2017 WannaCry ransomware, spread via the NSA-originated EternalBlue exploit and affecting over 300,000 computers in 150 countries, showed how unpatched Windows systems can cripple health and financial services. That precedent informs the October 2026 AI-driven ARTEX breach of South Korea’s Shinhan Bank and Yegaram Savings Bank, exposing 68,000 customers and prompting President Lee Jae-Myung to call for stricter AI security rules.
