yaklang/ntlm-relay-coercion

Libro de jugadas para la retransmisión NTLM y la coerción de autenticación. Útil para capturar y retransmitir autenticación NTLM con el fin de escalar privilegios a través de objetivos de retransmisión SMB, LDAP, HTTP o MSSQL, combinado con PetitPotam, PrinterBug y otros métodos de coerción.

¿Qué es ntlm-relay-coercion?

Este skill, `yaklang/ntlm-relay-coercion`, es un libro de jugadas para tácticas ofensivas de retransmisión NTLM (NT Lan Manager) y coerción de autenticación. Está diseñado para ser utilizado en pruebas de penetración y evaluación de seguridad, donde el objetivo es capturar hashes NTLM de autenticaciones y retransmitirlos a otros servicios (como SMB, LDAP, HTTP o MSSQL) para autenticarse y escalar privilegios dentro de una red corporativa. El skill integra técnicas de coerción como PetitPotam y PrinterBug (MS-RPRN), que fuerzan a servidores o estaciones de trabajo a autenticarse contra un atacante, proporcionando así los hashes necesarios para la retransmisión. Es compatible con plataformas como Ketida (el framework YAK) y herramientas como impacket, respondiendo a escenarios de movimiento lateral. Su utilidad radica en automatizar el proceso de configuración del servidor de retransmisión, la selección de objetivos y la ejecución de la coerción, lo que acelera la explotación de vulnerabilidades de autenticación delegada y falta de firma SMB.

Documentación

¿Qué hace ntlm-relay-coercion?

Libro de jugadas para la retransmisión NTLM y la coerción de autenticación. Útil para capturar y retransmitir autenticación NTLM con el fin de escalar privilegios a través de objetivos de retransmisión SMB, LDAP, HTTP o MSSQL, combinado con PetitPotam, PrinterBug y otros métodos de coerción.

Visión General

Este skill automatiza el proceso de:

  • Configurar un servidor de retransmisión NTLM (SMB, HTTP, etc.).
  • Coaccionar a máquinas objetivo (controladores de dominio, servidores) para que se autentiquen contra el atacante.
  • Retransmitir la autenticación capturada a otros servicios para escalar privilegios.

Plataformas Soportadas

  • Ketida (framework YAK)
  • Impacket (ntlmrelayx.py)

Requisitos

  • Acceso a la red donde se ejecutará la retransmisión.
  • Herramientas como impacket instaladas y en el PATH.
  • Capacidad para ejecutar scripts YAK.

Uso

  1. Identificar objetivos potenciales (servidores, estaciones de trabajo).
  2. Configurar el servidor de retransmisión apuntando al servicio objetivo (por ejemplo, SMB, LDAP).
  3. Ejecutar la coerción (PetitPotam, PrinterBug, etc.) contra la víctima para iniciar la autenticación.
  4. El servidor de retransmisión captura y retransmite la autenticación automáticamente.

Ejemplo

# Configurar retransmisión hacia un controlador de dominio vía SMB
relay_target = "smb://192.168.1.10"
coercion_method = "PetitPotam"
victim = "192.168.1.20"

# Ejecutar
run_ntlm_relay(relay_target, coercion_method, victim)

Notas

  • Asegúrate de que el tráfico de red permita la retransmisión (sin firma SMB, etc.).
  • Probar en un entorno controlado antes de usar en producción.
