Adversaries may use JamPlus to proxy the execution of a malicious script. JamPlus is a build utility tool for code and data build systems. It works with several popular compilers and can be used for generating workspaces in code editors such as Visual Studio.(Citation: JamPlus manual)

Adversaries may abuse the JamPlus build utility to execute malicious scripts via a .jam file, which describes the build process and required dependencies. Because the malicious script is executed from a reputable developer tool, it may subvert application control security systems such as Smart App Control.(Citation: Cyble)(Citation: Elastic Security Labs)
