Investigation of Malicious Portable Executable File Detection on the Network using Supervised Learning Techniques

Malware continues to be a critical concern for everyone from home users to enterprises. Today, most devices are connected through networks to the Internet. Therefore, malicious code can easily and rapidly spread. The objective of this paper is to examine how malicious portable executable (PE) files can be detected on the network by utilizing machine learning algorithms. The efficiency and effectiveness of the network detection rely on the number of features and the learning algorithms. In this work, we examined 28 features extracted from metadata, packing, imported DLLs and functions of four different types of PE files for malware detection. The returned results showed that the proposed system can achieve 98.7% detection rates, 1.8% false positive rate, and with an average scanning speed of 0.5 seconds per file in our testing environment
