Description
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)
How GTK Cyber trains on this
GTK Cyber's Threat Hunting with Data Science course teaches you to build machine-learning detections for techniques like this across the MITRE ATT&CK framework, including the stealth, Execution tactic this technique falls under. Practitioner-led, focused on real detections, not memorizing technique IDs.
