Abstract

Phishing is one of the oldest types of cyber-attack, which mostly comes in the form of camouflaged URLs to delude the users to disclose their personal information for malevolent purposes of the attacker. It is one of the easiest ways of inducing people into revealing their personal credentials including credit card details. Usually, most phishing attacks come up as fake websites pretending to mimic a trustworthy website, and the attackers use these malicious website URLs for successful data breaches. Therefore, it is a necessity to filter up which URLs are benign, and which are malicious. This study proposes three non-hybrid deep learning models, namely CNN (1D), LSTM, GRU, and four hybrid deep learning models, namely GRU-LSTM, LSTM-LSTM, BI (GRU)-LSTM, and BI (LSTM)-LSTM. Based on the results obtained, it was found that BI (GRU)-LSTM model was the best performing model with an accuracy of 93.91%, precision of 93.94 %, recall of 93.38 %, and F1-Score of 93.66 %. Thus, the primary objective of this paper is to provide an insight into the hybrid deep learning approaches in phishing URL detection by evaluating their accuracy, precision, recall, and f1 score.
