The Power of Social Engineering: Unveiling the Depth of Red Team Exercises

Understanding the Growing Threat of Social Engineering

Social engineering attacks have become increasingly prevalent in the cyber landscape, with attackers relying on these tactics as an effective approach to compromise businesses. According to the recently released Verizon Data Breach Investigations Report (DBIR), about one in every six attacks includes a social engineering component. As a result, social engineering has also become a necessary part of red team exercises and penetration tests, with more providers expanding their service offerings to include social engineering attack emulation and more in-depth reporting on human-focused attacks.

The Success of Social Engineering Attacks

In a red team exercise, Alethe Denis, a security consultant at Bishop Fox, often presents the targets with the exact email templates that her team intends to use, such as a dress-code missive from human resources. Surprisingly, even with this knowledge, the attacks almost always succeed. Denis highlights the fact that HR-based pretexts are extremely common and successful, yet individuals still fall victim to them. This underscores that even when people are aware of the tactics used in social engineering attacks, they can still be easily manipulated.

Emulating Attackers and Emphasizing Detection and Response

The shift in red team engagements and penetration testing today is focused on emulating attackers rather than solely outfoxing defenders. It is essential to understand the weaknesses and vulnerabilities in an organization’s environment to recommend technical controls that can prevent phishing and social engineering attacks. By including social engineering in penetration-testing engagements, companies gain insight into specific weak points in their training and environment, such as lax security protocols and a lack of security awareness among employees.

Attackers continue to gather passive intelligence on their targets, making it harder for businesses to defend against attacks. Mitigating endpoint security, especially social engineering, is crucial since it reveals how people react to urgent situations and whether they are willing to disclose personal or intellectual information.

The Importance of Purple Teaming

Incorporating a “purple team” approach, where red teams work collaboratively with internal security teams, is critical for organizations. Rather than solely providing a list of vulnerabilities, penetration testers must coordinate with the defensive team to ensure they understand the vulnerabilities and how to mitigate them. This approach provides a holistic view of an organization’s security posture and allows for a more effective response to social engineering attacks.

Recommendations for Protecting Against Social Engineering

Companies need to ensure their security operations are prepared to respond to successful social engineering attacks and implement measures to prevent initial compromises. Some recommended strategies include:

1. Implementing Browser Rules

Putting rules in the browser that prevent people from visiting newly registered domains can help businesses minimize the risk of falling victim to social engineering attacks. These rules can restrict access to potentially malicious websites.

2. Deploying Multifactor Authentication

Rolling out multifactor authentication provides an additional layer of security to protect against unauthorized access. This helps in preventing attackers from successfully breaching an organization’s systems and gaining control of sensitive information.

3. Conducting Regimented Compliance-driven Phishing Exercises

While training efforts and security awareness training can help individuals identify manipulation tactics, they should not be relied upon as the sole protection against social engineering attacks. However, these exercises are valuable for educating employees about the risks and raising awareness about potential threats.

Overall, organizations must take proactive steps to safeguard against social engineering attacks. By understanding the evolving threat landscape, adopting a purple team approach, and implementing appropriate security measures, companies can better protect themselves from the potentially devastating consequences of social engineering attacks.
