Did you know that 98% of successful cyberattacks rely on psychological manipulation? While companies invest millions in firewalls and detection systems, attackers have found an easier way: exploiting human trust, curiosity, and urgency. Social engineering now poses the greatest threat to organizations of all sizes, accounting for 68% of security breaches, according to the Verizon Data Breach Investigations Report 2024. In this article, we explore what this technique really is and why your weakest link could be your own team.
What is social engineering?
Social engineering is the art of manipulating people into revealing confidential information or performing actions that compromise security. Unlike technical attacks that exploit vulnerabilities in software, social engineering exploits vulnerabilities in human behavior. Its effectiveness lies in the fact that it does not need to find flaws in systems, but rather convince a person to voluntarily open the door.
Types of social engineering attacks that are dominating
1. PersonalizedPhishing (Spear Phishing)
- How it works: Hyper-personalized emails that appear to come from trusted contacts, using information gathered from social media and public sources
- Current example: An attacker impersonates the HR director, announcing “benefit updates” with a malicious link
- New development: Use of AI to analyze writing styles and create messages indistinguishable from legitimate ones
2. Advanced Vishing (Voice Phishing)
- How it works: Phone calls pretending to be from technical support, banks, or authorities, requesting credentials or immediate action
- Real-life example: Employees of a multinational company transferred $25M USD after receiving a call pretending to be from the CFO
- Trend: Impersonation of familiar voices using accessible voice synthesis technologies
3. Baitingwith physical devices
- How it works: Leaving infected USB devices in public areas of offices, parking lots, or cafeterias
- Statistics: 45% of people connect USB devices they find, according to a Google study
- Evolution: Now includes tampered cell phone chargers in airports and coworking spaces
4. Sophisticated pretexting
- How it works: Creation of elaborate and credible scenarios to gradually extract information
- Example: An attacker poses as an internal auditor requesting access to systems “for a routine review.”
- Current situation: Pretexts now include compliance with new regulations, such as the Cybersecurity Framework Act
5. Digital Quid Pro Quo
- How it works: Offering a benefit in exchange for information or access
- Example: “Cybersecurity advisors” offering free assessments in exchange for administrator credentials
- New: Fake offers of legitimate software updates that install malware
Why social engineering is so effective
These attacks work because:
- They exploit basic human emotions: urgency, curiosity, and fear of conflict
- They use psychological principles: Reciprocity, authority, scarcity
- They bypass technical controls: They do not require software vulnerabilities
- They are difficult to detect: They appear to be legitimate communications

Conclusion: Beyond Awareness
Social engineering will continue to evolve, but prepared organizations can significantly reduce their risk. Effective protection requires a multi-layered approach that combines:
- Ongoing training and realistic drills
- Clear identity verification policies
- Technical controls that limit potential damage
- An organizational culture that rewards secure verification
