Social Engineering Masterclass: Hacking the Human#

The most sophisticated firewall can be bypassed by a polite phone call. Social engineering targets the weakest link in any security chain: the human being.

The Psychology of Influence#

Attackers use Cialdini's principles of persuasion:

1. Authority: "This is the CEO calling."
2. Urgency: "Your account will be locked in 5 minutes!"
3. Scarcity: "Only 2 spots left."
4. Reciprocity: "I'll do you a favor if you help me out."

Attack Vectors#

1. Phishing (Email)#

• Spear Phishing: Targeted attacks using OSINT (Open Source Intelligence) to craft personalized emails.
• Clone Phishing: Copying a legitimate email and replacing the link.

2. Vishing (Voice)#

• AI Voice Cloning: In 2025, attackers use AI to clone the voice of executives to authorize fraudulent transfers.
• Caller ID Spoofing: Making the call appear to come from a trusted internal number.

3. Physical Breaches#

• Tailgating: Following an authorized person through a secure door.
• USB Drops: Leaving infected USB drives in the parking lot.

Defense#

Training is the only defense. Regular phishing simulations and security awareness training are essential to build a "human firewall."
