New Datasets for Dynamic Malware Classification
share
Nowadays, malware and malware incidents are increasing daily, even with various anti-viruses systems and malware detection or classification methodologies. Many static, dynamic, and hybrid techniques have been presented to detect malware and classify them into malware families. Dynamic and hybrid malware classification methods have advantages over static malware classification methods by being highly efficient. Since it is difficult to mask malware behavior while executing than its underlying code in static malware classification, machine learning techniques have been the main focus of the security experts to detect malware and determine their families dynamically. The rapid increase of malware also brings the necessity of recent and updated datasets of malicious software. We introduce two new, updated datasets in this work: One with 9,795 samples obtained and compiled from VirusSamples and the one with 14,616 samples from VirusShare. This paper also analyzes multi-class malware classification performance of the balanced and imbalanced version of these two datasets by using Histogram-based gradient boosting, Random Forest, Support Vector Machine, and XGBoost models with API call-based dynamic malware classification. Results show that Support Vector Machine, achieves the highest score of 94 91 most common gradient boosting-based models, achieves the highest score of 90 and 80 the baseline results of VirusShare and VirusSample datasets by using the four most widely known machine learning techniques in dynamic malware classification literature. We believe that these two datasets and baseline results enable researchers in this field to test and validate their methods and approaches.
