Malicious JavaScript is one of the most common tools for attackers to exploit the vulnerability of web applications. It can carry potential risks such as spreading malware, phishing, or collecting sensitive information. Though there are numerous types of malicious JavaScript that are difficult to detect, generalizing the malicious script’s signature can help catch more complex JavaScripts that use obfuscation techniques. This paper aims at detecting malicious JavaScripts based on structure and attribute analysis of abstract syntax trees (ASTs) that capture the generalized semantic meaning of the source code. We apply a graph convolutional neural network (GCN) to process the AST features and get a graph representation via neural message passing with neighborhood aggregation. The attention layer enriches our method to track pertinent parts of scripts that may contain the signature of malicious intent. We comprehensively evaluate the performance of our proposed approach on a real-world dataset to detect malicious websites. The proposed method demonstrates promising performance in terms of detection accuracy and robustness against obfuscated samples.
