Social engineering, which is the manipulation of people to gain unauthorized access to information or resources, is one of the greatest threats in the field of cybersecurity. These techniques use psychological aspects of human behavior to induce victims to reveal confidential information, perform specific actions, or install malicious software. In the context of penetration testing, social engineering plays a key role, allowing for simulation of realistic attack scenarios that can reveal weaknesses in both technical and procedural security of an organization.
Penetration testing, also known as pentests, is one of the basic tools used by security specialists to assess the security status of IT systems. They involve conducting controlled attacks on systems, applications, and networks to identify and fix vulnerabilities before they are exploited by real attackers. Pentests can include both manual and automated tests, and their scope often includes aspects related to social engineering.
The purpose of this article is to discuss social engineering techniques used in penetration testing and present the threats that can be revealed through these techniques. In the following sections, we will present the basic principles of social engineering, discuss the most commonly used techniques, present examples of threats revealed through these tests, and present methods of protection against such attacks.
Fundamentals of Social Engineering
Social engineering is a term that refers to a broad spectrum of activities aimed at manipulating people to induce them to reveal confidential information or perform specific actions. These techniques rely on exploiting psychological mechanisms such as trust, fear, greed, or curiosity.
Definition and Essence of Social Engineering
Social engineering involves using human psychology to gain access to information, systems, or physical spaces. It is a process of manipulating victims to induce them to take actions they would normally consider suspicious or dangerous. Social engineering can take various forms, from simple phone scams to sophisticated phishing scenarios.
Examples of Historical Attacks Using Social Engineering
One of the most famous cases of social engineering is the activity of Kevin Mitnick, one of the most famous hackers in history. Mitnick successfully used social engineering techniques to gain access to computer systems and data from companies around the world. Another example is the case of Edward Snowden, who, although not a typical example of social engineering, used trust and his professional positions to gain access to secret government information.
Psychological Aspects of Human Behavior Manipulation
People are susceptible to manipulation due to various psychological mechanisms. For example, phishing technique often uses fear of consequences (e.g., threat of bank account closure) or promise of gain (e.g., lottery win) to induce victims to click on a malicious link. Other techniques may exploit greed (e.g., promise of free software) or curiosity (e.g., messages about controversial topics).

Social Engineering Techniques Used in Penetration Testing
Social engineering is often used in penetration testing to assess how well an organization handles threats arising from human susceptibility to manipulation. Below we present the most commonly used techniques.
Phishing and Spear Phishing
Phishing involves sending fake emails that appear to come from trusted sources to extract confidential information such as passwords or credit card details. Spear phishing is a more advanced form of phishing in which messages are personalized and directed at specific individuals or organizations. An example could be an email pretending to be correspondence from a colleague, containing a link to a malicious website.
Pretexting
Pretexting involves creating a false scenario (pretext) to induce a victim to reveal information. For example, an attacker may impersonate an IT department employee, asking for access to a user account to resolve an alleged technical problem.
Baiting
Baiting is a technique that involves offering something desirable in exchange for information or performing a specific action. For example, an attacker may leave an infected USB drive in public places, hoping that someone will pick it up and connect it to a computer, thereby infecting the system.
Tailgating and Piggybacking
Tailgating and piggybacking are methods of physically gaining access to protected areas. Tailgating involves following an authorized person entering a secured area, while piggybacking is a situation where an attacker asks an authorized person for permission to enter, e.g., while carrying a heavy load.
Watering Hole Attacks
Watering hole attacks involve infecting frequently visited websites to infect visitors’ computers. Attackers identify websites that are popular among the target user group and then place malicious code on them.
Examples of Threats Revealed Through Social Engineering
Social engineering can reveal various threats that can have serious consequences for an organization.
Data and Identity Theft
Attacks using social engineering can lead to theft of personal and corporate data, which can then be used for financial fraud, identity theft, or blackmail.
Information System Security Breaches
Disclosure of authentication data by victims of phishing or pretexting attacks can lead to unauthorized access to information systems. Attackers can thus take control of systems, install malicious software, or steal confidential information.
Disclosure of Sensitive Corporate Information
Attacks using social engineering can lead to disclosure of trade secrets, business plans, marketing strategies, or financial data. Such leaks can have serious consequences for a company’s competitiveness and reputation.
Financial and Reputational Losses
Successful social engineering attacks can lead to significant financial losses, both direct (e.g., theft of financial funds) and indirect (e.g., costs associated with repairing the effects of an attack, loss of customers). Additionally, such incidents can seriously damage a company’s reputation, which can have long-term negative effects.
Implementing Social Engineering in Penetration Testing
Penetration testing using social engineering is conducted to assess how well an organization is prepared for such threats.
Procedures and Stages of Penetration Testing Using Social Engineering
These tests typically include several key stages: planning, reconnaissance, attack execution, and results analysis. Planning includes defining test objectives and selecting appropriate techniques. Reconnaissance involves gathering information about the attack target, such as employee contact details or organizational structure. Attack execution is the actual implementation of social engineering scenarios, and results analysis includes assessing attack effectiveness and identifying weaknesses.
Selecting Targets and Attack Techniques
Penetration testing using social engineering can be directed at general employees or at specific individuals or departments that are particularly vulnerable to attacks. Attack techniques are selected based on the organization’s characteristics and test objectives.
Examples of Successful Penetration Tests
In one case, a company conducted penetration tests during which security specialists used phishing techniques, sending fake emails pretending to be internal company correspondence. As a result, over 60% of employees clicked on a malicious link, revealing serious gaps in security awareness in the company.
Protection Against Social Engineering Attacks
Effective protection against social engineering attacks requires a multi-layered approach that includes both employee training and technical security measures.
Employee Training and Awareness Raising
Regular training on threats arising from social engineering and how to recognize them is key. Employees should be aware of the various techniques used by attackers and know how to respond to them.
Implementing Security Procedures
Organizations should implement and enforce security procedures, such as strong password policies, identity verification for people requesting access to information, and data management rules.
Technical Protection Measures Against Attacks
Anti-phishing software, intrusion detection systems, and other security tools can help identify and block social engineering attack attempts.
The Role of IT Security Teams
IT security teams play a key role in monitoring and responding to security incidents. Regular penetration testing and security audits can help identify and fix weaknesses.
Summary
Social engineering is a powerful tool in the hands of attackers, but also a key element of penetration testing that helps organizations identify and fix security vulnerabilities. Regular training, implementation of security procedures, and use of technical protection measures can significantly increase an organization’s resistance to such attacks. Continuous monitoring and updating of security strategies are necessary to effectively protect against increasingly advanced social engineering techniques. We encourage further discussion and exploration of the topic to stay up to date with the latest trends and methods in the field of cybersecurity.
The rules without which this test does harm
A social engineering test differs from the others in that its subject is people, which is why it needs rules agreed before it starts. Three of them decide the outcome: results are reported in aggregate rather than by name; scenarios avoid pretexts that cause real distress (illness in the family, redundancies, payroll); and someone has the authority to stop the campaign at any moment. A test without those rules produces a number and destroys the trust that is needed during a real incident.
That is how social engineering tests are set up: scenarios and scope agreed with the client before anything is sent.
