Abstract

Systems and method for the detection of obfuscated malware in JIT code are provided. JIT code portions may be retrieved from a repository, and metadata associated with the JIT code may be determined. The JIT code and associated metadata may be hashed to determine a hash value that is compared to a cache of hash values corresponding to previously analyzed JIT code portions. If the JIT code portion has not been previously analyzed the JIT code portion may be parsed into a byte stream for execution in a JIT runtime environment in a virtual machines. The runtime data may be analyzed using signature matching, heuristic rule matching, n-gram analysis, and RNN analysis. If malware is detected, the JIT code portion, associated metadata, and analysis results may be provided for generation of an alert.
