CRITICAL LEVEL

1. Executive Summary

해당 사용자는 비업무 시간대(02:14 AM)에 회사 내부망에 접속하여 대량의 민감 데이터(Source Code, PII)를 조회하였으며, 이와 동시에 생성형 AI(ChatGPT) 서비스에 해당 데이터를 입력하는 패턴이 탐지되었습니다. Risk Trajectory 분석 결과, 단순 업무 실수가 아닌 의도적인 데이터 유출 시도 가능성이 매우 높음(98.2%)으로 판단됩니다.

Detected: Prompt Injection

Detected: Mass File Upload
