Idea
Phishing detection model delivering fast, accurate, and scalable web threat identification without external references.
Research Paper
Core Innovation
This paper introduces SpecularNet, a novel hierarchical graph autoencoding architecture that models webpage DOM trees with directional, level-wise message passing. Unlike prior reference-based or multimodal methods, it operates solely on domain and HTML structure, enabling fast, end-to-end inference with competitive accuracy and much lower computational cost.
Why It Matters
Phishing causes widespread credential theft and financial fraud, challenging existing detectors that rely on external data and heavy computation. SpecularNet offers a practical, scalable solution with fast inference on standard hardware, improving real-world phishing defense and enabling broader adoption across industries.
