Two of South Korea's largest Christian institutions, including SaRang Church and Yoido Full Gospel Church, have launched formal investigations into extensive data breaches linked to suspected AI-assisted cyberattacks. Cyber authorities discovered malicious web shells installed on church servers, facilitating unauthorized remote access and data exfiltration. At SaRang Church alone, attackers compromised personal identity and administrative records belonging to 286 employees and roughly 89,000 congregants. The broader wave of cyber intrusions has simultaneously targeted major South Korean financial and public institutions. Cybersecurity specialists indicated that threat actors leveraged single sign-on vulnerabilities and compromised third-party administrative credentials to gain initial access. Affected religious organizations responded by terminating external connections, rotating server credentials, updating firewall perimeters, and collaborating with private cybersecurity firms and government agencies, including the Korea Internet and Security Agency. The incident highlights expanding cyber risks facing non-profit and faith-based hubs maintaining massive personal databases.
