Abstract

En 中文

Graph Neural Networks (GNNs) have found widespread application in malware detection tasks in recent years, aiming to uncover the malicious nature of target processes by aggregating neighborhood information via different relations. However, current GNN-based malware detection models are primarily designed for static graphs or fixed-window dynamic graphs; they often overlook the correlation between distinct continuous behaviors and specific attacks (e.g., code injection), leading to a disruption in the attack’s continuity and incurring substantial computing overhead. This paper introduces a novel model dubbed DynMD, designed to enhance the efficiency of malware detection on streaming behavioral data via energy-based dynamic graph representation learning. Concretely, DynMD investigates an energy function to adaptively partition windows, facilitating the construction of a lossless malware dynamic heterogeneous graph. More importantly, DynMD proposes a unique time-aware dynamic graph learning method to capture energy-concordant dynamic neighborhoods. This approach involves both intra-graph and inter-graph message propagation, promoting dynamic graph learning while avoiding time-consuming and repetitive computations. Experimental results on three real-world malware datasets show that DynMD improves detection accuracy by up to 3.99% and achieves detection 3.81× to 5.33× faster than the MG-DVD framework, identifying malware within an average of 40 seconds of execution.
