Key Cybersecurity Insights for Security Leaders

  • Data Breach and Compromise Is the Primary Risk: Data breach and compromise accounts for 49.07% of Dark Web threat categories and 40.33% of threat types.
  • Information and Public Administration Require Priority Visibility: Information and Public Administration together account for 40% of all Dark Web threats targeting South Korea.
  • Espionage Is a Significant Threat Category: Espionage and state-sponsored activity accounts for 18.52% of Dark Web threat categories.
  • Credential Theft Is a Key Entry Point: Unauthorized Access and Credentials rises to 13.17% by threat type, showing its role as an operational path into larger attacks.
  • Phishing and Social Engineering Support Broader Campaigns: Phishing and Social Engineering accounts for 12.83% of threat types, indicating heavy use of human-targeted entry methods.
  • Malware and Ransomware Remain Meaningful: Malware and Ransomware accounts for 10.03% of threat categories and 9% of threat types.
  • Finance and Manufacturing Lead Ransomware Exposure: Finance and Insurance accounts for 38.46% of ransomware targeting, followed by Manufacturing at 30%.
  • Qilin Requires Focused Tracking: Qilin accounts for 26.7% of ransomware incidents targeting South Korea, making it the leading named ransomware actor.
  • Ransomware Defense Must Cover Long-Tail Actors: The “Other” category accounts for 65.3% of ransomware activity, showing that known groups alone do not cover most risk.
  • Coupang and Generic Login Pages Drive Phishing: Coupang-related lures account for 12% of phishing page titles, while “Sign in to your account” and “Login” together account for 16%.
  • HTTPS-Based Phishing Requires Updated Awareness: 71.3% of phishing sites use HTTPS, requiring security teams to move beyond padlock-based training and rely on domain, content, and reputation analysis.

Why This Report Matters for CISOs

CISOs in South Korea must prepare for a threat environment where data theft, credential access, phishing, and espionage overlap. Information services and public administration face the highest Dark Web exposure, while finance and manufacturing carry greater ransomware pressure. Phishing campaigns also target consumer trust, banking access, cryptocurrency platforms, hospitality services, and generic account login flows.

Security teams should prioritize Dark Web monitoring, credential exposure detection, phishing defense, ransomware readiness, and intelligence-led detection engineering. Stronger MFA enforcement, privileged access monitoring, secure backups, endpoint hardening, and monitoring for state-linked TTPs can help reduce the risk of data compromise, operational disruption, and unauthorized access.
