Abstract

A script analysis platform may obtain a script associated with content wherein the script includes one or more functions that include one or more expressions. The script analysis platform may parse the script to generate a data structure and may traverse the data structure to determine the one or more functions and to determine properties of the one or more expressions, wherein traversing the data structure includes evaluating one or more constant sub-expressions of the one or more expressions. The script analysis platform may analyze the properties of the one or more expressions to determine whether the script exhibits malicious behavior. The script analysis platform may cause an action to be performed concerning the script or the content based on determining whether the script exhibits malicious behavior.
