What is Social Engineer Toolkit (SET) ?

A Social Engineer Toolkit or SET also known as Social Engineering Toolkit is a set of apps used by white hat (or black hat) hackers in order to perform penetration testing on an individual or organization’s cybersecurity defenses.

Won’t like to confuse you by giving a very elaborate answer. Let me put it briefly. The SET (Social-Engineer Toolkit) is designed specifically to perform advanced attacks. Written by David Kennedy with much input from the community, SET was designed to be released with the www.social-engineer.org launch. It has now become a standard tool for penetration testing. SET helps execute targeted, focused attacks against an organization or person and can be used by hackers, both ethical and others.
