Adversaries may abuse msiexec.exe to proxy execution of malicious payloads. Msiexec.exe is the command-line utility for the Windows Installer and is thus commonly associated with executing installation packages (.msi). The Msiexec.exe binary may also be digitally signed by Microsoft. Adversaries may abuse msiexec.exe to launch local or network accessible MSI files. Msiexec.exe can also execute DLLs.

how MITRE says to see it

Detection of Msiexec Abuse for Local, Network, and DLL Execution

Detection of msiexec.exe execution where command-line arguments reference remote MSI packages, UNC paths, HTTP/HTTPS URLs, or DLLs, correlated with subsequent module loads and/or network connections to previously unseen destinations.

what reduces it

M1026 Privileged Account Management. Restrict execution of Msiexec.exe to privileged accounts or groups that need to use it to lessen the opportunities for malicious usage.
M1042 Disable or Remove Feature or Program. Consider disabling the `AlwaysInstallElevated` policy to prevent elevated execution of Windows Installer packages.
