• Abstract: The threat of phishing attacks in financial systems is continuously growing. Therefore, protecting sensitive information from unauthorized access is paramount. This paper discusses the critical need for robust email phishing detection. Several existing methods, including blacklists and whitelists, play a crucial role in detecting phishing attempts. Nevertheless, these methods possess inherent limitations, emphasizing the need for the development of a more advanced solution. Our proposed solution presents a pioneering Natural Language Processing (NLP) approach for phishing email detection. Leveraging semantic similarity and TFIDF (Term Frequency-Inverse Document Frequency) analysis, our solution identifies keywords in phishing emails, subsequently evaluating the semantic similarities with a dedicated phishing dataset, ultimately contributing to the enhancement of cybersecurity and NLP domains through a robust solution for detecting phishing threats in financial systems. Experimental results show the accuracy of our phishing detection method can reach 79.8 percent according to TF-IDF analysis, while it can reach 67.2 percent according to semantic analysis.
