Toward Reliable Malicious JavaScript Detection in Obfuscated Code

Published
Record updated

Summary

Researchers study how code obfuscation affects static analysis methods for detecting malicious JavaScript. They find existing detectors fail against medium-strength obfuscation and propose SeGra, which uses data flow features, random walks and sequence conversion of graph structure. SeGra reaches 99.5% accuracy on medium-strength obfuscated code and 70.4% on low-strength code, with 67.1% on high-strength code after learning from low-strength samples.
