Cuando quieres analizar las vulnerabilidades de un servidor web, puedes hacerlo con muchísimas herramientas y te recomiendo que no te quedes solo con una… ya que los falsos positivos existen.

Hoy traigo la herramienta muy conocida llamada Nikto que la gran mayoría de vosotros seguro que conocéis.

¿Que es Nikto?

Nikto es un escáner de vulnerabilidad de línea de comandos de software gratuito que escanea servidores web en busca de archivos / CGI peligrosos, software de servidor obsoleto y otros problemas. Realiza comprobaciones genéricas y específicas del tipo de servidor. También captura e imprime las cookies recibidas.

¿Como usar Nikto?

La verdad que es muy fácil de utilizar.
