Security professionals understand the importance of systematically testing defenses to ensure they are effective. Various security operations, such as penetration testing, phishing simulation, vulnerability scanning, and container scanning, help validate control operations and provide feedback on the effectiveness of countermeasures in place. However, in the process of testing, technologists often focus too much on the technology ecosystem and overlook the human element.
Testing the resilience of users is just as crucial as testing the security profile of applications, servers, and networks. Assessing how likely users are to fall victim to manipulation, confidence schemes, social engineering, and other malicious campaigns is essential. While there are limited tools available to evaluate users’ resistance to these attacks, the Social-Engineer Toolkit (SET) offers a helpful option.
SET is a group of utilities primarily used in a red team context for launching social engineering attacks. Developed by TrustedSec founder Dave Kennedy, the open-source app enables security professionals to execute various attacks, such as creating realistic-looking websites, conducting browser-based attacks, and more. Before utilizing SET, it is crucial to ensure that the planned use is ethical, lawful, and legal. Conducting thorough research and consulting with internal counsel is necessary to avoid any illegal or unethical actions.
Installing SET can be done on platforms where it is preinstalled, such as penetration-focused Linux distributions like Kali and BlackArch, or by following instructions in the project’s readme for other platforms. Running SET from the command line using the setoolkit command opens up a range of attack tools available for penetration tests and social engineering campaigns. The toolkit offers different attack techniques, such as spear-phishing, website attack vectors, infectious media generation, creating payloads and listeners, mass mailing attacks, and more.
When it comes to using SET as part of a broader strategy, the toolkit has multiple enterprise use cases. It can support pen testing activities that include a social engineering component and be utilized in security awareness training programs to test employees’ reactions to various attack vectors. Additionally, SET can be used to test hardening measures, such as checking if autorun is disabled on managed endpoints.
In conclusion, exploring the capabilities of SET not only benefits red team operations but also supports blue team activities by enhancing security awareness and testing defense measures. With the right approach and creativity, SET can be a valuable tool in enhancing overall security posture and resilience against social engineering attacks. Time invested in understanding and utilizing SET effectively is time well spent in strengthening cybersecurity defenses.
