Original title: Hacker Uses Generative AI to Breach 90 Companies and Steal 8.2 Million Records
Investigators link AI-assisted intrusions at 60 victims and extortion demands totaling 360 million won.
Seoul police said a 32-year-old suspect, identified only as A, was arrested on October 15 and referred to prosecutors on October 23 for alleged network intrusion and extortion. The campaign, which police say began in September 2025, hit academies, hospitals, golf courses, universities and a corporate affiliate. From late August 2026 he allegedly used generative AI to widen targeting. Threatening emails sought payment from 38 organizations; police said they recovered the stolen data and are checking whether it reached dark-web markets.
Unconfirmed: Police have not named the AI system, model or vulnerabilities, and it is unclear whether payments were collected or data reached dark-web markets.
- Intrusions at 60 of about 90 organizations were attributed to AI-assisted activity.
