Social Engineering Attacks: Human Factor Security Analysis
Introduction
Social engineering represents the most successful attack vector in cybersecurity, exploiting human psychology rather than technical vulnerabilities to bypass security controls and gain unauthorized access.
Psychological Foundations
Cognitive Biases
- Authority bias: Deference to perceived authority figures
- Reciprocity principle: Obligation to return favors
- Social proof: Following group behavior patterns
- Scarcity mindset: Urgency in limited-time offers
Emotional Manipulation
- Fear tactics: Creating panic or anxiety
- Curiosity exploitation: Leveraging natural inquisitiveness
- Trust building: Establishing false relationships
- Greed exploitation: Promising unrealistic rewards
Attack Classification
Pretexting
Creating fabricated scenarios to extract information:
- Impersonation of authority figures
- False emergency situations
- Fake service requests
- Counterfeit business relationships
Phishing Variants
- Email Phishing: Mass email campaigns
- Spear Phishing: Targeted individual attacks
- Whaling: Executive-focused campaigns
- Vishing: Voice-based social engineering
- Smishing: SMS-based attacks
Physical Social Engineering
- Tailgating: Following authorized personnel
- Dumpster diving: Information gathering from discarded materials
- Shoulder surfing: Visual eavesdropping
- Impersonation: False identity assumption
Advanced Attack Techniques
Business Email Compromise (BEC)
Sophisticated attacks targeting business processes:
- CEO fraud schemes
- Invoice manipulation
- Payroll redirection
- Wire transfer fraud
Watering Hole Attacks
Compromising frequently visited websites to target specific user groups
Supply Chain Social Engineering
Targeting trusted third-party relationships to access primary targets
