讲座摘要

Phishing website attack, as one of the most persistent forms of cyber threats, evolves and remains a major cyber threat. Previous deep representation-based methods fail to analyze two important modalities of website content: textual information and visual design. Moreover, the interpretability of these deep learning based methods is limited. As such, we propose a multi-modal hierarchical attention model (MMHAM) which jointly learns the deep fraud cues from the three major modalities of website content for phishing website detection. Specifically, MMHAM features an innovative shared dictionary learning approach for aligning representations from different modalities in the attention mechanism. In our evaluation experiments, the proposed MMHAM provided a hierarchical interpretability system from which we could develop phishing threat intelligence to inform phishing websites detection at different levels.
