Deep Analysis and Utilization of Malware's Social Relation Network for Its Detection

摘要

To combat with the evolving malware attacks, many research efforts have been conducted on developing intelligent malware detection systems. In most of the existing systems, resting on the analysis of file contents extracted from the file samples (e.g., binary n-grams, system calls), data mining techniques such as classification and clustering have been used for malware detection. However, ignoring the social relations among these file samples (i.e., utilizing file contents only) is a significant limitation of these malware detection methods. In this paper, (1) instead of using file contents extracted from the collected samples, we conduct deep analysis of the social relation network among file samples and study how it can be used for malware detection; (2) resting on the constructed file relation graph, we perform large scale inference by propagating information from the labeled samples (either benign or malicious) to detect newly unknown malware. A comprehensive experimental study on a large collection of file sample relations obtained from Comodo Cloud Security Center is performed to compare various malware detection approaches. Promising experimental results demonstrate that the accuracy and efficiency of our proposed method outperform other alternate data mining based detection techniques.
