Two South Korean megachurches investigate suspected AI-assisted cyberattacks after records show sub-agent and automated-report traces

What changed

Reuters reported on October 7 that Yoido Full Gospel Church and Sarang Church in Seoul are investigating suspected cyberattacks. Cybersecurity company Oasis Security said attack records found on an overseas server contained references to “sub-agents” and extensive reports that appeared automated, suggesting AI tools may have been used during the intrusion. Yoido Full Gospel Church said its initial analysis indicated data related to about 850,000 members may have been compromised. The available evidence supports only suspected AI assistance; it does not establish the specific model, attacker identity or degree of autonomous execution.
