Towards Personalized Anti-Phishing: Counterfactual Explanation Approach - Extended Abstract

In today's digital landscape, phishing attacks persist as a formidable challenge, highlighting the need for robust strategies to mitigate individual risk. While advanced machine learning techniques have excelled in identifying those most susceptible to phishing, existing research has primarily focused on refining prediction accuracy rather than leveraging this understanding to mitigate risk. To bridge this gap, we present a novel counterfactual explanation approach aimed at identifying the specific traits that heighten an individual's vulnerability to phishing. Our approach integrates uncertainties and causal insights from the data generation process, producing actionable intelligence to effectively lower individual susceptibility. This enables us to tailor personalized recommendations to reduce individual's vulnerability. Through experimentation, we assess the efficacy of our methodology and demonstrate capacity to reduce susceptibility to phishing. These findings emphasize the importance of personalized interventions, arming individuals with the knowledge necessary to improve their online security protocols.
