synacktiv/gpoddityNTLM 릴레이를 통한 Active Directory GPO 익스플로잇을 자동화하여, 악성 GPO 템플릿 생성, 위치 스푸핑, 명령 실행을 통해 권한 상승 및 측면 이동을 가능하게 합니다.
GPOddity 프로젝트는 NTLM 릴레이(및 기타 방법)를 통해 GPO 공격 벡터를 자동화하는 것을 목표로 합니다.
공격에 대한 자세한 내용과 도구 사용 방법 데모는 다음 문서를 참조하세요: https://www.synacktiv.com/publications/gpoddity-exploiting-active-directory-gpos-through-ntlm-relaying-and-more
다음 명령어로 pipx를 통해 GPOddity를 설치할 수 있습니다:
$ python3 -m pipx install git+https://github.com/synacktiv/GPOddity
또는 저장소를 클론하고 의존성을 설치하여 수동으로 GPOddity를 설치할 수 있습니다:
$ git clone https://github.com/synacktiv/GPOddity
$ python3 -m pip install -r requirements.txt
$ python3 gpoddity.py --help
