Abstract: Cyberattacks are intentional attacks on computer systems, networks, and devices. Malware, phishing, drive-by downloads, and injection are popular cyberattacks that can harm individuals, businesses, and organizations. Most of these attacks trick internet users by using malicious links or webpages. Malicious webpages can be used to distribute malware, steal personal information, conduct phishing attacks, or perform other malicious activities. Detecting such malicious websites is a tedious task for internet users. Therefore, locating such a website in cyberspace requires an automated detection tool. Currently, machine learning techniques are being used to detect such malicious websites. The majority of recent studies derive a limited number of features from webpages (both benign and malicious) and use machine learning (ML) algorithms to detect fraudulent webpages. However, these constrained capabilities might not use the full potential of the dataset. This study addresses this issue by identifying malicious websites using both the URL and webpage content features. To maximize detection accuracy, both ngrams and vectorization methods in natural language processing are adopted with minimum feature-set. To exploit the full potential of the dataset, the proposed approach derives the 22 common linguistic features of the URL and generates ngrams from the domain name of the URL. The textual content of the webpages was also used. The research employs seven machine learning algorithms with three vectorization methods. The outcome reveals that the proposed method outperformed the results of previous studies.
