Our phishing detection system consists of four main layers:
Data Collection Layer – Collects phishing and legitimate data.
Feature Extraction Layer – Extracts relevant phishing-related attributes.
Data Generation Layer – Uses GANs to generate synthetic phishing data.
Training & Testing Layer – Utilizes transformer models for classification.
