Abstract

Smishing (SMS phishing) is a cyber threat that is growing rapidly, and it's a tactic in which attackers use SMS messages to deceive users and trick them into revealing their private information or unintentionally installing harmful applications. As mobile devices are used everywhere, detecting smishing messages has become a very important yet difficult task in cybersecurity. In the present study, the authors conduct a comparative analysis of several deep learning models, namely, the Long Short-Term Memory (LSTM), Bidirectional LSTM (Bi LSTM), Convolutional Neural Network (CNN), and a combination of CNN-LSTM, for the detection of smishing. The experiments are conducted on publicly available SMS datasets, and performance is evaluated using accuracy, precision, recall, F1 Score, and a confusion matrix. The findings indicate that deep learning-based approaches yield significantly better results than traditional methods, with hybrid architectures leading in overall performance.
