What it detects

This rule detects MSBuild.exe launched by a command shell or PowerShell without a project or solution file on the command line, an anomaly consistent with the process hollowing target abused by HijackLoader to run AsyncRAT. Genuine MSBuild builds reference a project, solution, or response file.
