Your firewalls and endpoint protection can’t stop this attack—because the weakness isn’t in your systems. It’s in your people.

Social engineering attacks are responsible for over 70% of breaches today, yet most companies still underestimate the risk. In this post, we’ll break down:

  • How attackers manipulate employees into handing over access

  • The most common social engineering tactics we see in real-world pentests

  • How to protect your business from these attacks

1. The #1 Reason Social Engineering Works: Trust

Hackers exploit human nature, not just technology. They know people:
Don’t question authority (e.g., pretending to be IT or management)
Want to be helpful (e.g., holding the door open for a “technician”)
Act under pressure (e.g., urgent emails about “account security issues”)

Example Attack:
An attacker calls pretending to be IT support, saying,
🚨 “We detected a security issue on your account. I just need to verify your login to fix it.”
📌 9 out of 10 employees fall for this—handing over credentials to an attacker.

2. The Most Common Social Engineering Attacks

🔹 Phishing Emails – Fake emails tricking employees into clicking malicious links.
🔹 Phone Pretexting – Attackers posing as IT, HR, or management to steal info.
🔹 Tailgating – Walking into secure areas without a badge, pretending to be a visitor.
🔹 USB Drop Attacks – Attackers leave malicious USBs labeled “Confidential” to tempt employees into plugging them in.

3. How to Defend Against Social Engineering

Train employees to recognize social engineering tactics.
Use phishing simulations to test staff awareness.
Implement strict identity verification (never trust requests for credentials over email or phone).
