Beginner Topic 8 of 51 Security & Cryptography

Social Engineering

Manipulating people rather than systems.

How it works

Social engineering manipulates people, rather than technology, into giving up access or information. Techniques exploit trust, authority, urgency, fear, curiosity and helpfulness through pretexting with invented scenarios, impersonating IT or executives, baiting with infected USB drives, tailgating into buildings and phone calls to help desks. Attackers research targets through social media and public records to appear credible.

Step-by-step walkthrough

  1. The attacker researches the target.
  2. They phone pretending to be IT support.
  3. They invent urgency and authority.
  4. The employee hands over a code or password.
  5. Defence is training, verification procedures and a culture where saying no is safe.

Where it is used

Penetration testers and red teams run authorized social-engineering tests, and organizations build security awareness, verification procedures and a reporting culture to resist it.

Common pitfall

Technical defenses can be bypassed by one persuaded employee. Blaming victims discourages reporting. Policies such as callback verification for payment changes, multi-person approval and strict identity checks for password resets reduce risk. Limit what is shared publicly and treat unexpected urgency as a red flag.
