Detection of Malicious Websites using Machine Learning
 Šulák, Ladislav ; Černocký, Jan (oponent) ; Beneš, Karel (vedoucí práce)
This thesis deals with the problem of web-based malware focusing on the analysis and detection of malicious JavaScript placed on the client side using machine learning techniques.Proposed approach benefits from both known and new observations regarding differencesbetween malicious and benign samples. Such approach has a potential to detect brand newexploits and zero-day attacks. System for such detection has been implemented using multiple machine learning models. Performance of the models has been evaluated with F1-scoreby executing multiple experiments. According to the experiments, the application of decision tree classifiers was the most effective option. The most effective model was Adaboostclassifier which reached F1-score up to 99.16 %. This model worked with 200 instances ofrandomized decision tree based on Extra-Trees algorithm. Multi-layer Perceptron was thesecond-best model with achieved F1-score up to 97.94 %.
