Necesitaran Bajarse el metasploit de metasploit o la maquina virtual de Backtrack.

Aprenderan a obtener acceso a una maquina usando solamente los hash de las contraseñas almacenadas en el sistema sin ni siquera saber la verdadera contraseña… ¡very cool!. Tambien podran intentar añadir un usuario a una maquina remota (quiza un controlador de dominio) usando esta vez solo los tokens almacenados de un pobre administrador del dominio logueado en una maquina con todos los privilegios… ¡very creepy!

Jeff Moser de Moserware.com se dió a la tarea de escribir (y de ilustrar) un libreto (o debería mejor llamarlo un guión) en el cual el personaje principal es AES.

Pues bien, por cortesía de Jeff Moser les dejo con esta obra en cuatro actos que nos enseña de la manera mas didactica posible, la historia de AES, algunos fundamentos de criptografía, los detalles del algoritmo y las matemáticas sobre las cuales se basa el mismo.
