Phishing attacks present a persistent and ev.lv.ng threat in the cybersecurity land-scape, necessitating the dev.lopment of more sophisticated detection methods. Traditional machine learning approaches to phishing detection hav. relied heav.ly on feature engineering and hav. often fallen short in adapting to the dynamically changing patterns of phishing Uniform Resource Locator (URLs). Addressing these challenge, we introduce a framework that integrates the sequential data processing strengths of a Recurrent Neural Network (RNN) with the hyperparameter optimization prowess of the Whale Optimization Algorithm (WOA). Our model capitalizes on an extensiv. Kaggle dataset, featuring ov.r 11,000 URLs, each delineated by 30 attributes. The WOA’s hyperparameter optimization enhances the RNN’s performance, ev.denced by a meticulous v.lidation process. The results, encapsulated in precision, recall, and F1-score metrics, surpass baseline models, achiev.ng an ov.rall accuracy of 92%. This study not only demonstrates the RNN’s proficiency in learning complex patterns but also underscores the WOA’s effectiv.ness in refining machine learning models for the critical task of phishing detection.
