South Korean megachurches are investigating suspected cyberattacks affecting hundreds of thousands of members.

Researchers say attackers used advanced AI agents and web shells to breach administrative networks.

The hackers exploited ERP web shell installations and insecure direct object reference flaws.

Reports say 850,000 member records across multiple institutions were exposed.

Investigators hope to trace the AI tools used and identify those responsible.
