Which among the following tools can help in identifying IoEs to evaluate human attack surface?

The Social-Engineer Toolkit (SET) is an open-source penetration testing framework designed specifically for social engineering. It allows security professionals to simulate various social engineering attacks, such as phishing campaigns, malicious web requests, and credential harvesting. By using SET to test an organization's employees, defenders can identify weaknesses in human processes and awareness. These weaknesses are Indicators of Exposure (IoEs) that constitute the human attack surface, providing insight into how susceptible the organization is to manipulation-based attacks.

A. securiCAD is a tool for automated threat modeling and attack simulation on IT architectures, not focused on the human element.
B. Amass is a network mapping and asset discovery tool used to identify an organization's external infrastructure attack surface.
C. Skybox Security provides a platform for cybersecurity posture management, focusing on network-level vulnerability and threat analysis.
