Social engineering is the art of manipulating people into giving up confidential information or performing actions that compromise security. Unlike traditional hacking, which targets systems and software, social engineering targets human psychology—making it one of the most dangerous and effective forms of cyberattack.
Common Social Engineering Techniques
- Phishing: Fake emails or websites trick users into revealing login credentials or clicking malicious links.
- Multi Factor Authentication (MFA) Fatigue: A tactic where repeated MFA prompts are sent to targeted employees until one mistakenly approves it.
- Vishing (Voice Phishing): Attackers impersonate IT support or bank officials over the phone to extract sensitive data.
- Pretexting: A fabricated story is used to gain trust and access—like pretending to be a vendor or colleague.
- Baiting: USB drives or free downloads are used to lure victims into installing malware.
- Tailgating: An unauthorized person follows an employee into a secure area without proper credentials.
Real-World Example: MGM Resorts Breach
In 2023, attackers impersonated an employee and tricked the help desk into resetting credentials. Vishing and Multi Factor Authentication (MFA) fatigue tactics were used in the attack. Within hours, they gained access to critical systems—highlighting how a single phone call can bypass even the most advanced security tools.
Why It Works
Humans are naturally trusting, helpful, curious and not to forget, susceptible—traits that social engineers exploit. Even the most tech-savvy individuals can fall victim if they are caught off guard.
How to Defend Against Social Engineering
- Security Awareness Training: Regular training helps employees recognize and respond to suspicious behavior.
- Verify Requests: Always confirm identity before sharing sensitive information—even internally.
- Use Multi-Factor Authentication (MFA): Adds an extra layer of protection even if credentials are compromised.
- Report Incidents Promptly: Encourage a culture of transparency and quick reporting.
