In today’s digital era, cybercrime has evolved beyond technical hacking into a psychological battlefield. Social engineering involves manipulating human emotions such as trust, fear, urgency, and curiosity to trick individuals into revealing sensitive information or performing unsafe actions. This paper reviews six research studies that explore the nature, methods, and impacts of social engineering in cybercrime. It presents a critical discussion on the psychology behind these attacks, the role of artificial intelligence, and the strategies that can be adopted to counteract them. The findings emphasize the urgent need for public awareness, psychological training, legal reform, and technological innovation to safeguard against such manipulative threats.
