A Deep Malware Detection Method Based on General-Purpose Register Features

摘要

Based on low-level features at micro-architecture level, the existing detection methods usually need a long sample length to detect malicious behaviours and can hardly identify non-signature malware, which will inevitably affect the detection efficiency and effectiveness. To solve the above problems, we propose to use the General-Purpose Registers (GPRs) as our features and design a novel deep learning model for malware detection. Specifically, each register has specific functions and changes of its content contain the action information which can be used to detect illegal behaviours. Also, we design a deep detection model, which can jointly fuse spatial and temporal correlations of GPRs for malware detection only requiring a short sample length. The proposed deep detection model can well learn discriminative characteristics from GPRs between normal and abnormal processes, and thus can also identify non-signature malware. Comprehensive experimental results show that our proposed method performs better than the state-of-art methods for malicious behaviours detection relying on low-level features.
