T1218.007: Msiexec
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).[1] 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.[2][3] Since it may be signed and native on Windows systems, msiexec.exe can be used to bypass application control solutions that do not account for its potential abuse. Msiexec.exe execution may also be elevated to SYSTEM privileges if the AlwaysInstallElevated policy is enabled.[4]
Analyst context for executives and security teams
Msiexec matters because it is a normal, Microsoft-signed Windows installer utility that can also be used to run malicious MSI packages or DLLs from local or network locations. For leaders, the risk is not that msiexec exists, but that trusted system tooling can make malicious execution look like routine software installation, especially where application control or installer policy is weak.
Executive priority
Prioritize this as a Windows control-validation issue: can the organization distinguish approved software installation from suspicious msiexec-driven execution? The ATT&CK relationships show use across multiple campaigns, groups, and malware families, so this is relevant to SOC readiness, incident triage, privileged access governance, and audit evidence around application control and least privilege. A key executive question is whether policies such as AlwaysInstallElevated are known, governed, and monitored because MITRE notes they may allow msiexec execution to be elevated to SYSTEM privileges.
Technical view
Validate visibility and controls around msiexec.exe process execution on Windows. Focus on command-line arguments, parent/child process context, local versus network-accessible MSI paths, DLL execution patterns, and privilege context. Because the official detection field is not provided, use the related detection strategy DET0158 as direction to validate local, network, and DLL execution abuse rather than assuming existing coverage. Treat msiexec as a signed living-off-the-land binary under System Binary Proxy Execution, where allowlisting based only on publisher or file signature may be insufficient.
Likely telemetry
- Windows process creation events for msiexec.exe, including full command line
- Parent and child process relationships involving msiexec.exe
- File path evidence for MSI packages or DLLs executed by msiexec.exe
- Network path or remote share indicators referenced by msiexec.exe command lines
- Privilege and user context for msiexec.exe execution, including elevated or SYSTEM context
Detection direction
- Baseline normal enterprise software deployment behavior so alerts do not overwhelm teams during legitimate installation activity.
- Alert or hunt for msiexec.exe launching content from unusual local paths, user-writable locations, or network-accessible locations when that context is available.
- Review msiexec.exe command lines for DLL execution and other nonstandard installer usage referenced by ATT&CK and LOLBAS context.
- Correlate msiexec execution with parent processes that are unusual for software deployment, while accounting for legitimate management tools.
- Validate whether signed-binary or publisher-based application control rules permit msiexec abuse without inspecting arguments or allowed installation sources.
Mitigation priorities
- Apply privileged account management principles: restrict administrative installation rights, enforce least privilege, and monitor privileged installer activity.
- Review and govern installer-related policies, especially AlwaysInstallElevated, and disable risky configurations where not required.
- Use application control with rules that account for msiexec abuse patterns, not only Microsoft signature trust.
- Reduce attack surface by disabling or removing unnecessary features, programs, or installer capabilities where operationally feasible.
- Maintain audit evidence showing who can install software, from where packages may be run, and how exceptions are approved.
Analyst notes and limits
This object is a Windows sub-technique of System Binary Proxy Execution under the stealth tactic. MITRE provides no official detection text for this technique, but the supplied relationship identifies DET0158, Detection of Msiexec Abuse for Local, Network, and DLL Execution. The relationship set includes multiple campaigns, groups, and software entries using this technique; that supports defensive prioritization but should not be read as evidence of current activity in any specific environment.
This take is limited to the supplied ATT&CK STIX fields, references, and relationships. Local risk depends on Windows estate size, installer workflows, application control design, logging coverage, privileged access model, and policy state. No claim is made that a specific organization is exposed or that any detection is guaranteed.

G0095: Machete
Machete is a suspected Spanish-speaking cyber espionage group that has been active since at least 2010. It has primarily focused its operations within Latin America, with a particular emphasis on Venezuela, but also in the US, Europe, Russia, and parts of Asia. Machete generally targets high-profile organizations such as government institutions, intelligence services, and military units, as well as telecommunications and power companies.[1][2][3][4]
G0082: APT38
APT38 is a North Korean state-sponsored threat group that specializes in financial cyber operations; it has been attributed to the Reconnaissance General Bureau.[1] Active since at least 2014, APT38 has targeted banks, financial institutions, casinos, cryptocurrency exchanges, SWIFT system endpoints, and ATMs in at least 38 countries worldwide. Significant operations include the 2016 Bank of Bangladesh heist, during which APT38 stole $81 million, as well as attacks against Bancomext [2] and Banco de Chile [2]; some of their attacks have been destructive.[1][2][3][4]
North Korean group definitions are known to have significant overlap, and some security researchers report all North Korean state-sponsored cyber activity under the name Lazarus Group instead of tracking clusters or subgroups.
S0631: Chaes
Chaes is a multistage information stealer written in several programming languages that collects login credentials, credit card numbers, and other financial information. Chaes was first observed in 2020, and appears to primarily target victims in Brazil as well as other e-commerce customers in Latin America.[1]

DOWNIISSA is a shellcode downloader that has been used by MirrorFace since at least 2022 to deploy payloads, including the LODEINFO backdoor.[1]
C0057: 3CX Supply Chain Attack
The 3CX Supply Chain Attack was the first publicly reported case of one supply chain compromise triggering another, leading to a cascading, two-stage intrusion. The initial supply chain attack began when a 3CX employee downloaded and executed a trojanized, end-of-life version of the X_Trader trading software from Trading Technologies. This provided UNC4736, a threat cluster associated with AppleJeus, access to the 3CX environment. From there UNC4736 compromised the Windows and macOS build environments used to distribute the 3CX desktop application to their customers.[1] While 3CX serves more than 600,000 customers and 12 million users, only a subset of systems were affected. Subsequent targeting focused on victims in the defense and cryptocurrency sectors, where attackers deployed secondary payloads such as Gopuram for credential theft and persistence.[2] The campaign began in late 2022 and was disrupted after security vendors publicly reported the compromise in March 2023.[3][4]
C0047: RedDelta Modified PlugX Infection Chain Operations
RedDelta Modified PlugX Infection Chain Operations was executed by Mustang Panda from mid-2023 through the end of 2024 against multiple entities in East and Southeast Asia. RedDelta Modified PlugX Infection Chain Operations involved phishing to deliver malicious files or links to users prompting follow-on installer downloads to load PlugX on victim machines in a persistent state.[1]
