Social-Engineer Toolkit (SET)

The Social-Engineer Toolkit (SET) is an open-source framework for automating social-engineering attacks like phishing and credential harvesting. It provides templates, payloads, and automation to emulate common human-targeted attack vectors for testing and training. SET is primarily intended for authorized security assessments and requires strict ethical controls when used. The toolkit integrates with payload handlers and supports custom scenarios for realistic training exercises. Security teams use SET to evaluate the effectiveness of user training and technical controls against social-engineering threats.
