Una herramienta muy interesante que arroja mucha información con una sola ejecución es ADPeas.ps1:
PsExec es una herramienta ligada a la suite de Sysinternals de Microsoft y permite la ejecución de procesos en sistemas remotos. Es particularmente útil para administradores de sistemas, pero también es conocido por ser utilizado por atacantes o pentesters para moverse lateralmente a través de una red.
Contexto de Autenticación: Cuando interactúas con Directorio Activo (AD), lo haces a través de un contexto de autenticación, que esencialmente dicta qué derechos y permisos tiene el usuario o proceso actual. Si estás ejecutando comandos en una máquina comprometida con un contexto local (por ejemplo, una shell reversa que no tiene un token de autenticación para AD), es posible que no puedas consultar o interactuar con el AD aunque estés en un dominio.
Cambiar Contexto: Usando PsExec, puedes ejecutar comandos o programas en el contexto de otro usuario, o incluso en el contexto de SYSTEM si tienes los permisos necesarios. Al hacerlo, estás esencialmente "cambiando" tu contexto de autenticación, lo que puede darte los derechos necesarios para interactuar con AD.
En resumen, aunque no es estrictamente necesario usar PsExec para salir del contexto de usuario local y enumerar AD (hay otras técnicas y herramientas que pueden lograr lo mismo), PsExec es una herramienta versátil que permite a los atacantes y pentesters cambiar de contexto de autenticación y moverse lateralmente a través de una red. Por lo tanto, es una herramienta útil en escenarios donde se necesita ampliar el alcance o cambiar el contexto para interactuar con AD.
Un usuario administrator local no puede interactuar con el dominio y por lo tanto es necesario salir del contexto y migrar a NT AUTHORITY SYSTEM. Estos pasos se realizaran desde una sesion de RDP:
PS C:\Users\Administrator> net group /domain
The request will be processed at a domain controller for domain infinity.com.
System error 5 has occurred.
Access is denied.Para salir del contexto, se utiliza PSExec:
PS C:\Users\Administrator\Desktop> .\PsExec64.exe -i -s cmd.exeDespues de esto saldra una nueva pestaña que si podra interactuar con el dominio:
Después de lo anterior, tendremos permisos necesarios para interactuar con el dominio desde ADPeas.ps1:
