Pentestly: un framework que combina Python y Powershell para facilitar el pentesting

Está claro que actualmente hay una tendencia clara a usar Python y Powershell para el desarrollo de muchas herramientas de hacking. Pentestly es un framework muy útil que combina varias de éstas para facilitar el desarrollo de un pentesting:

- recon-ng - base de datos de backend
- wmiexec.py - facilita la ejecución de comandos Powershell vía WMI
- smbmap.py - utilidad para enumerar recursos SMB compartidos
- Invoke-Mimikatz.ps1 - implementación de Mimikatz en Powershell
- powercat.ps1 - funcionalidad Netcat-esque en Powershell
- Invoke-Shellcode.ps1 - usa Meterpreter en Powershell
- CrackMapExec - inspiración para el servidor Mimikatz en Pentestly

Crear nuevos módulos es bastante fálcil en Pentestly. A partir del código de skeleton.py:
from libs.pentestlymodule import PentestlyModule

class Module(PentestlyModule):

    meta = {
        'name': 'Your module name goes here',
        'author': 'Developer name goes here',
        'description': 'Description of the module goes here',
        'query': 'SQL QUERY whose result is passed to your module',
        'options': (
            ('Option1', 'Default Value', Required-True/False, 'Description of option'),
        ),
    }

    def module_pre(self):
        # Optional
        # Happens before your module

    def module_run(self, data):
        # Required
        # data is the result from the SQL query set in the options

        ### Few magic functions
        # self.query - Perform an SQL query on the internal database
        results = self.query("select * from pentestly_creds")

        # self.output - print default information to the user
        self.output("Performed an SQL query")
        self.output(results)

        # self.alert - print successful message to the user
        self.success("Yay! We performed successful work")

    def module_post(self):
        # Optional
        # Happens after your module

Los puntos claves aquí son poner la información de meta y la función module_run.

El script debe situarse luego en el directorio  modules/ o en el personal ~/.pentestly/modules para portabilidad.
