Abstract
Malware, a short name for malicious software is an emerging cyber threat. Various researchers have proposed ways to build advanced malware detectors that can mitigate threat actors and enable effective cybersecurity decisions in the past. Recent research implements malware detectors based on visualized images of malware executable files. In this framework, a malware binary is converted into an image, and by extracting image features and applying machine learning methods, the malware is identified based on image similarity. In this research work, we implement the Image visualization-based malware detection method and conduct an empirical analysis of vari-ous learners for selecting a candidate learning classifier that can provide better prediction performance. We evaluate our framework using the following malware datasets, Search And RetrieVAl of Malware (SARVAM), Xue-dataset, and Canadian Institutes for Cyber Security (CIC) datasets. Our experiments include the following learning algorithms, Linear Regression, Random Forest, K-Nearest Neighbor (KNN), Classification and Decision Tree (CART), Support Vector Machine (SVM), Multi-Layer Perceptron (MLP), and deep learning-based Convolutional Neural Network (CNN). This image-visualization-based method proves to be effective in terms of prediction accuracy. Some conclusions emerge from our initial study and find that a Con-volutional Neural Network (CNN) algorithm provides relatively better performance when used against SARvAM and various malware datasets. The CNN model achieved a high performance of F1-score and accuracy in the binary classification task reaching 95.70% and 99.50%, consecutively. The model in the multi-classification task achieved of 95.96% and 99.30% (F1-score and accuracy) for detecting malware types. We find that the KNN model outperforms other traditional classifiers.
