The Social-Engineer Toolkit
(SET) is specifically designed to perform advanced attacks against
the human element. Since there is no patch for human stupidity, this
is why social engineering seems the biggest weapon for hackers. When
social engineering toolkit combine with Armitage and metasploit then
it can do wonders, you can test the security by hacking into Windows,
Facebook and other OS and even web application.

Armitage is a scriptable red
team collaboration tool for Metasploit that visualizes targets,
recommends exploits, and exposes the advanced post-exploitation
features in the framework.

This video tutorial is based on both
SET (Social engineering toolkit) and Armitage to demonstrate the
hacking and exploitation process.
