Social Engineering: The Hack That Doesn't Need Code

The weakest link is always human

Over 90% of successful cyberattacks start with social engineering — manipulating people instead of systems. Here are the techniques and how to defend against them.

Common techniques

• Phishing — Fake emails mimicking trusted brands. Check the sender domain carefully.
• Pretexting — "Hi, I'm from IT. I need your password to fix your account." Always verify through official channels.
• Baiting — USB drives labeled "Confidential Salaries" left in parking lots. Never plug in unknown devices.
• Tailgating — Following someone through a secure door without scanning your own badge.
• Vishing — Voice phishing via phone calls impersonating banks or tech support.

Defense strategies

1. Run regular phishing simulations
2. Create a "verify before trust" culture
3. Make reporting suspicious activity easy and stigma-free
4. Use hardware security keys for critical accounts

Technology can't fix human nature — but awareness training dramatically reduces risk.
