PhishAgent: A Robust Multimodal Agent for Phishing Webpage Detection
<|reference_start|>PhishAgent: A Robust Multimodal Agent for Phishing Webpage Detection: Phishing attacks are a major threat to online security, exploiting user vulnerabilities to steal sensitive information. Various methods have been developed to counteract phishing, each with varying levels of accuracy, but they also encounter notable limitations. In this study, we introduce PhishAgent, a multimodal agent that combines a wide range of tools, integrating both online and offline knowledge bases with Multimodal Large Language Models (MLLMs). This combination leads to broader brand coverage, which enhances brand recognition and recall. Furthermore, we propose a multimodal information retrieval framework designed to extract the top k relevant items from offline knowledge bases, utilizing all available information from a webpage, including logos, HTML, and URLs. Our empirical results, based on three real-world datasets, demonstrate that the proposed framework significantly enhances detection accuracy and reduces both false positives and false negatives, while maintaining model efficiency. Additionally, PhishAgent shows strong resilience against various types of adversarial attacks.<|reference_end|>
