2026년 4월, 미국의 인공지능(AI) 기업 앤스로픽(Anthropic)은 자사의 최신 프론티어 모델인 '클로드 미토스(Claude Mythos)'에 권한이 없는 외부인이 접속했다는 주장이 제기됨에 따라 내부 조사에 들어갔다. 클로드 미토스는 강력한 사이버 보안 능력을 갖추어 악용 위험이 크다는 이유로 일반 공개가 제한된 모델이었으나, 소규모 그룹이 제3자 계약업체 포털 등을 통해 약 2주간 접근한 것으로 알려졌다. 앤스로픽은 해당 모델의 보안 취약점 발견 능력이 공격자에게 넘어갈 경우 발생할 위험을 경고해 왔으며, 이번 사건으로 인해 고성능 AI 모델의 관리 체계에 대한 우려가 커지고 있다.
