Why This Report Matters for CEOs

Cyber risk in South Korea affects more than IT systems. Data breaches, espionage, ransomware, phishing, and credential compromise can disrupt operations, expose sensitive records, damage customer trust, threaten intellectual property, and create financial or regulatory consequences. The concentration of Dark Web threats against information services and public administration shows that attackers prioritize high-value data and infrastructure, while ransomware pressure on finance and manufacturing highlights the business impact of downtime.

Business leaders should treat cybersecurity as a strategic business and resilience priority. Strong cyber resilience, intelligence-driven visibility, identity protection, ransomware readiness, phishing defense, and business continuity planning are essential for protecting operations, customers, intellectual property, and long-term stability in South Korea’s evolving threat landscape.
