## Social Engineering Toolkit Overview
* **Defining Social Engineering:** The manipulation of individuals to divulge confidential information. It accounts for over 90% of successful data breaches.
* **What is SET?** An open-source Python framework created by Dave Kennedy (TrustedSec) for authorized penetration testing, pre-installed on Kali Linux.

## Technical Implementation & Modules
* **Installation:** Basic setup using `sudo apt install set` and launch via `sudo setoolkit`.
* **Spear-Phishing:** Attacks targeting specific users using malicious PDFs, DOCs, or EXEs integrated with Metasploit payloads.
* **Website Attack Vectors:** Includes Java Applet attacks, Metasploit browser exploits, credential harvesting (cloning sites like Facebook/Gmail), and Tabnabbing.
* **Additional Tools:** Infectious media generators for USB drives, mass mailer engines, and Arduino-based HID attacks.

## Defense & Mitigation
* **Security Awareness:** Training employees to recognize deception.
* **Technical Controls:** Implementing Multi-Factor Authentication (MFA), email/web filtering, and regular security testing.
* **Response:** Establishing a clear incident response plan to handle successful human-element breaches.
