Key Insights from South Korea’s Cyber Threat Landscape

• Information and Public Administration Are the Primary Targets: Information accounts for 20.22% of Dark Web threats, while Public Administration follows at 19.78%.
• The Top Five Sectors Carry Most Exposure: Information, Public Administration, Finance and Insurance, Retail Trade, and Manufacturing absorb roughly 75% of all Dark Web threat activity.
• Data Theft Leads the Threat Landscape: Data Breach and Compromise accounts for 49.07% of Dark Web threat categories and 40.33% of threat types.
• Espionage Holds Significant Ground: Espionage and state-sponsored activity accounts for 18.52% of threat categories, reflecting South Korea’s geopolitical threat environment.
• Credential Theft and Social Engineering Enable Larger Attacks: Unauthorized Access and Credentials accounts for 13.17% of threat types, while Phishing and Social Engineering accounts for 12.83%.
• Attack Motivation Shifts by Sector: Information and Public Administration dominate overall Dark Web exposure, while Finance and Insurance rises to 38.46% in ransomware and Banking reaches 23.53% in phishing.
• Manufacturing Faces High Ransomware Pressure: Manufacturing accounts for 30% of ransomware targeting, showing strong attacker interest in downtime-sensitive industries.
• Qilin Ransomware Leads Activity: Qilin accounts for 26.7% of ransomware incidents targeting South Korea, ahead of Nova and CoinbaseCartel at 4% each.
• Ransomware Activity Remains Fragmented: The “Other” category accounts for 65.3% of ransomware activity, showing that smaller and emerging operators drive most incidents.
• Phishing Is Concentrated Across Three Sectors: Information Services, Banking, and Accommodation and Food Services each account for 23.53% of phishing activity.
• Coupang Is the Top Phishing Lure: Coupang-related fake product review pages account for 12% of phishing page titles.

Why This Report Matters

South Korea’s threat landscape shows that cyber risk differs sharply by attack type. Dark Web activity concentrates around information services, public administration, finance, retail, and manufacturing, where sensitive records, credentials, IT infrastructure, and intellectual property hold high value. Espionage also plays a larger role than in many country profiles, with state-sponsored activity distributed across data breaches, credential theft, phishing, and malware.

Ransomware follows a different pattern, shifting heavily toward finance, insurance, and manufacturing, where downtime can create immediate financial pressure. Phishing follows another route, targeting information services, banking, hospitality, e-commerce, cryptocurrency, and generic credential-harvesting pages.

For South Korean organizations, effective defense requires more than one threat model. Data-rich sectors need Dark Web visibility and credential monitoring, finance and manufacturing need ransomware resilience, and customer-facing digital platforms need stronger phishing detection and brand protection.

Take Action Now
