Spear phishing in a barrel: Insights from a targeted phishing campaign

ABSTRACT Executives in many industries have fallen prey to socially engineered attacks known as spear phishing. Using highly targeted emails, social engineers trick victims into performing unintended actions by masquerading as legitimate actors. To shed light on effective spear phishing training, we conducted a multi-round experiment. Our results indicate that training users with individual loss messaging might increase the effectiveness of the training. Additionally, we found potential evidence that organizational training can lead to increased overall spear phishing awareness, even for those not directly trained. Despite these promising results, however, individuals’ susceptibility to highly targeted spear phishing attacks remains troubling for practitioners and researchers.
