방미통위, 롯데카드 CI 유출에 과태료 1125만원 부과

Lotte Card's breach exposing 1.29 million users' CI (Connecting Information) reveals systemic failures in corporate security practices and threatens Korea's digital identity infrastructure. The regulatory penalty and mandatory encryption requirements signal tightening compliance standards that will force businesses to prioritize security over operational convenience. This incident demonstrates that even major financial institutions can fail fundamental security practices, creating significant risks for consumers relying on online identification systems.
