Social engineering is a cybersecurity and behavioral science practice known as “the art of manipulation” that uses techniques to trick people into revealing sensitive information or performing compromising actions. Unlike traditional cyberattacks that exploit technological vulnerabilities, social engineering focuses on human trust.
Although the term was coined in 1894 by Dutch industrialist J.C. Van Marken, its use in cyberattacks became popular in the 1990s, with tactics such as phone calls to obtain login credentials or access to internal servers. Today, attacks have evolved to include threats such as phishing, spear phishing, and catfishing, which can result in significant financial loss.
In today’s article, we will delve into this art of manipulation and analyze the most common attacks and how we can protect ourselves against them.
Social engineering can be defined as the use of psychological manipulation to gain access to sensitive information, resources, or systems. Attackers known as “social engineers” use a variety of tactics to exploit human nature, including persuasion, intimidation, and deception.
Often, these attacks are the first step in a broader intrusion that may include data theft, financial fraud, or unauthorized access to computer networks. The key to a social engineer’s success is his or her ability to convince people to act against their own best interests.
Therefore, it could be said that the core of social engineering is the manipulation of human trust and emotions through convincing stories and false scenarios, because although defenses at the technological level are improving every day, human vulnerability remains an attractive target.
Social engineering is based on a deep understanding of human psychology. Social engineers use psychological principles such as authority, reciprocity, scarcity, and urgency to manipulate their victims. For example, a phishing message may create a sense of urgency (such as a security warning) that encourages the victim to act quickly without questioning the authenticity of the message.
Another key principle is trust. Social engineers often mimic the language and behavior of authority figures or people close to the victim to establish a relationship of trust. Once that connection is made, the victim is more likely to follow the attacker’s instructions.
Thus, using these psychological principles, social engineers often mimic the language and behaviors of authority figures or people close to them to establish a trust connection. Once this connection is established, the victim is more likely to follow the attacker’s instructions.
In addition, social engineers heighten emotions to manipulate their targets, such as threatening to lose an account to pressure users into giving up their credentials, or impersonating their boss by urgently requesting a wire transfer to instill fear of losing their job if orders are not followed. This use of fear and urgency is a common tactic to reduce the victim’s ability to think clearly.
Another common tactic is to promise something that seems too good to be true. Scammers often offer attractive rewards in exchange for small payments. Designed to look like irresistible opportunities, these offers prey on the greed or desire of victims who, lured by the promise, let down their guard and fall for the trap. If an offer seems too good to be true, it is probably a scam.
The latter tactic is often accompanied by a false sense of scarcity or limited time to provoke an impulsive response. This may include messages such as “offer valid only today” or “last units available” that encourage the victim to act immediately without considering the possible consequences.
The combination of these psychological principles with emotional manipulation and the promise of rewards is what makes social engineering so effective and dangerous.
There are several types of attacks that are designed to exploit a specific weakness in human behavior:
- Phishing: This is the most common method and involves sending fake emails or messages that appear to come from legitimate sources, such as banks or social networks. The goal is to trick the victim into revealing personal information, such as passwords or credit card numbers.
- Spear phishing: This is a more targeted form of phishing, where attackers customize messages to target a specific individual or group, making the attack more credible and effective.
- Vishing and smishing: These are attacks that use phone calls (vishing) or text messages (smishing). Attackers impersonate authority figures to convince the victim to share sensitive information.
- Pretexting: The attacker creates a fictitious scenario to deceive the victim. For example, pretending to be an employee of your company who needs access to the victim’s account to fix a technical problem.
- Baiting: This attack offers the victim something attractive, such as a free download or a prize, but with the intention of infecting their device with malware or stealing their credentials.
- Tailgating o piggybacking: These methods involve following someone through an access door, gaining access to a restricted area (physical or digital), relying on the person’s courtesy to leave the door open, or not questioning the intruder.
- Catfishing: Attackers create fake profiles on social networks to build trust with their victims to perform actions that benefit the attacker.
Protection against social engineering in cybersecurity does not depend on technology alone, but also requires a combination of awareness, education, and robust security practices.
To minimize this type of attack, strategies such as the following should be followed:
- Education and awareness: Educate employees and users about common types of attacks and how to recognize them. Simulating phishing attacks can be an effective way to reinforce these concepts.
- Source verification: Before sharing sensitive information, always verify the identity of the requestor through official channels and never provide credentials through suspicious links or phone numbers.
- Use multi-factor authentication (MFA): MFA adds an extra layer of security by requiring more than one form of verification before granting access to accounts or systems.
- Strict security policies: To reduce these attacks, policies can also be implemented that limit access to sensitive information and require formal procedures for requesting and sharing such information.
Conclusion
As we have seen throughout this article, social engineering in cybersecurity is a significant threat that exploits human vulnerability through psychological manipulation techniques rather than technological weaknesses.
As technology advances and security measures become more sophisticated, social engineers continue to refine their tactics, using persuasion, urgency, and imitation of authority figures to deceive their victims.
As a result, the key to protecting against these attacks lies not only in technological solutions, but also in ongoing user education and awareness, fostering a culture of security based on constant verification and caution in the face of suspicious requests.
By understanding the psychological principles behind social engineering and adopting preventive measures, it is possible to mitigate the risk and strengthen our defenses against this art of manipulation.
