Spear-Phishing Susceptibility Stemming From Personality Traits

This study explores the psychological aspects of social engineering by analyzing personality traits in the context of spear-phishing attacks. Phishing emails were constructed by leveraging multiple vulnerable personality traits to maximize the success of an attack. The emails were then used to test several hypotheses regarding phishing susceptibility by simulating a series of spear-phishing campaigns inside a software development company. The company's employees underwent a standard Big Five personality test, four different phishing emails over four weeks, and cybersecurity training. The results were aggregated before and after the cybersecurity course, and binary logistic regression analyses were performed at each phase of the phishing attack. The results show that personality traits correlate with phishing susceptibility under certain circumstances and pave the way for new methods of protecting individuals from phishing attacks.
