Sub-technique of: T1127
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.
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.
Platforms: Windows
Identify Attack Surface: Determine if the target environment is susceptible to JamPlus by examining the target platforms (Windows).
Assess Existing Defenses: Review whether mitigations for T1127.003 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.
Note: No Atomic Red Team tests available for this technique. See Atomic Red Team GitHub for updates.
Consider blocking or restricting JamPlus if not required.
