What is Social Engineering? (Types, Examples, and Attacks)

In the realm of cybersecurity, one of the most dangerous threats is social engineering. Unlike traditional cyber attacks that rely on technical vulnerabilities, social engineering exploits human psychology to gain unauthorized access to systems and sensitive information. Understanding social engineering, its types, and real-world examples can help you recognize and defend against these deceptive tactics.

What is social engineering?

Social engineering is a manipulation technique that takes advantage of human error to gain private information, access, or valuables. An attacker tricks an individual into divulging confidential information or taking actions that compromise security.

Types of Social Engineering Attacks

  1. Phishing
    • Phishing is the most common form of social engineering. Attackers send fake emails or messages posing as legitimate entities to trick recipients into providing sensitive information or downloading malicious attachments.
  2. Spearfishing
    • Spear phishing is a targeted form of phishing where attackers tailor their messages to specific individuals or organizations, often using personal information to appear more trustworthy.
  3. to pretend
    • With impersonation, an attacker creates a fictitious scenario, or excuse, to obtain private information. This may include impersonating a colleague, authority figure, or service provider.
  4. baiting
    • Baiting involves luring victims with the promise of a reward. For example, attackers can leave malware-infected USB drives in public places, hoping someone will pick them up and use them.
  5. Quid Pro Quo
    • This technique involves promising a benefit in exchange for information or access. An attacker can pretend to be IT support by offering help in exchange for login credentials.
  6. Tailgating
    • Tailgating, or “piggybacking,” involves an unauthorized person leading an authorized person into a restricted area. This often occurs in physical environments such as offices or secure buildings.

Examples of social engineering attacks.

  1. An example of a phishing email
    • An email purportedly from a bank asks the recipient to verify their account information due to suspicious activity. The link provided leads to a fake website designed to steal login credentials.
  2. An example of spearfishing
    • A high-ranking executive receives an email from what appears to be a trusted partner, requesting an immediate transfer of funds. The email includes personal details to make it look authentic, but it's a scam.
  3. An example of making excuses
    • An attacker calls an employee, claiming to be from the IT department, and requests the employee's login credentials to fix a fictitious problem.
  4. Example of batting
    • USB drives labeled “Confidential” are left in the company parking lot. Malware gets installed when curious employees install them on their computers.
  5. Example of Quid Pro Quo
    • An attacker calls random numbers within an organization, offering free software upgrades in exchange for login details.

Defense against social engineering attacks

  1. Education and Training
    • Regularly educate employees about social engineering tactics and how to recognize them. Training should include simulated fishing exercises.
  2. Verify applications.
    • Always verify the identity of the person requesting sensitive information. Use official channels to verify the legitimacy of the application.
  3. Use Multi-Factor Authentication (MFA).
    • Implement MFA to add an extra layer of security, making it harder for attackers to gain access to stolen credentials.
  4. Limit information sharing.
    • Be careful about information shared on social media and professional networks, as attackers often use this information to spearhead attacks.
  5. Incident Response Plan
    • Have a clear incident response plan to quickly address and mitigate the effects of a social engineering attack.
