While this digital transformation offers undeniable benefits, it simultaneously exposes users and institutions to significant cyber security threats. Malicious actors constantly seek out vulnerabilities in these systems, employing sophisticated methods to gain unauthorized access to sensitive data. One of the most alarming and effective tactics used by cybercriminals is social engineering. Rather than targeting technological flaws, social engineering exploits human behavior, manipulating individuals through deception, coercion, or the illusion of trust to bypass even the most advanced technical security controls. As traditional cyber security defenses such as multi-layered encryption, firewalls, and vulnerability patches grow more robust, attackers are shifting their focus to the human element, which is often the weakest link in the security chain. Unlike technical attacks that require in-depth knowledge of systems and code, social engineering preys on emotions like fear, urgency, curiosity, or helpfulness. These psychological manipulations make it easier for attackers to extract confidential data or financial information without triggering alarms. This paper explores the most common forms of Social Engineering (SE) attacks, including phishing, pretexting, baiting, and tailgating. It also delves into the psychological principles behind these tactics and outlines essential preventative strategies to mitigate the growing threat of social engineering in today’s cyber landscape.
