The Social Engineering Toolkit (SET) is an advanced, multifunctional, and easy-to-use computer-assisted social engineering toolset created by the founders of TrustedSec (https://www.trustedsec.com/). It helps you prepare the most effective way to exploit client-side application vulnerabilities, and makes a fascinating attempt to capture the target's confidential information (for example, e-mail passwords).

Some of the most efficient and useful attack methods employed by SET include targeted phishing e-mails with a malicious file attachment, Java applet attacks, browser-based exploitation, gathering website credentials, creating infectious portable media (USB/DVD/CD), mass-mailer attacks, and other similar multi-attack web vectors. This combination of attack methods provides you with a powerful platform to utilize and select the most persuasive technique that could perform an advanced attack against a human element.
