Smb/smb lookupsid
De www.metasploit-es.com.ar
El modulo "smb_lookupsid" realiza fuerza bruta en busquedas SID en un rango de objetivos para determinar que usuarios locales existen en el sistema. Sabiendo que usuarios existen en un sistema se puede acelerar enormemente cualquier intento posterior de iniciar sesion por fuerza bruta.
