지난해 개인정보 유출 신고 447건…'랜섬웨어·웹셸' 기승

Personal data breach reports in South Korea surged 45.6% to 447 cases in 2025, with ransomware and malware attacks accounting for 62% of incidents—evidence of intensifying global cyber threats. The nearly 60% increase in hacking-related breaches (from 171 to 276) reveals that organizations face increasingly sophisticated attack vectors including SQL injection, web shell exploits, and supply chain compromises. Urgent implementation of multi-layered security measures—security updates, encrypted backups, database encryption, and access controls—alongside dedicated security personnel and structural governance improvements is critical to defend organizational assets.
