Conducting Social Engineering Penetration Test

Conducting Social Engineering Penetration Test

Overview

Social engineering penetration testing assesses an organization's human attack surface through controlled simulation of real-world deception techniques. According to Verizon DBIR 2024, the human element is involved in approximately 68% of all breaches, with phishing remaining the dominant initial access vector. This skill covers phishing, vishing (voice phishing), smishing (SMS phishing), and physical pretexting campaigns using tools like GoPhish, the Social Engineer Toolkit (SET), and Evilginx.
