Query: indicators of Component Object Model and Distributed COM
Matching passage: T1175 Component Object Model and Distributed COM. Tactics: lateral movement, execution. Description: **This technique has been deprecated. Please use [Distributed Component Object Model](https://attack.mitre.org/techniques/T1021/003) and [Component Object Model](https://attack.mitre.org/techniques/T1559/001).** Adversaries may use the Windows Component Object Model (COM) and Distributed Component Object Model (DCOM) for local code execution or to execute on remote systems as part of lateral movement. COM is a component of the native Windows application programming interface (API) that enables interaction between software objects, or executable code that implements one or more interfaces.(Citation: Fireeye Hunting COM June 2019) Through COM, a client object can call methods of server objects, which are typically Dynamic Link Libraries (DLL) or executables (EXE).(Citation: Microsoft COM) DCOM is transparent middleware that extends the functionality of Component Object Model (COM) (Citation: Microsoft COM) beyond a local computer using remote procedure call (RPC) technology.(Citation: Fireeye Hunting COM June 2019) Permissions to interact with local and remote server COM objects are specified by access control lists (ACL) in the Registry. (Citation: Microsoft COM ACL)(Citation: Microsoft Process Wide Com Keys)(Citation: Microsoft System Wide Com Keys) By default, only Administrators may remotely activate and launch COM objects through DCOM. Adversaries may abuse COM for local command and/or payload execution. Various COM interfaces are exposed that can be abused to invoke arbitrary execution via a variety of programming languages such as C, C++, Java, and VBScript.(Citation: Microsoft COM) Specific COM objects also exists to directly perform functions beyond code execution, such as creating a [Scheduled Task/Job](https://attack.mitre.org/techniques/T1053), fileless download/execution, and other adversary behaviors such as Privilege Escalation and Persistence.(Citation: Fireeye Hunting COM June 2019)(Citation: ProjectZero File Write EoP Apr 2018) Adversaries may use DC
Near-miss passage: T1204.005 Malicious Library. Tactics: execution. Description: Adversaries may rely on a user installing a malicious library to facilitate execution. Threat actors may [Upload Malware](https://attack.mitre.org/techniques/T1608/001) to package managers such as NPM and PyPi, as well as to public code repositories such as GitHub. User may install libraries without realizing they are malicious, thus bypassing techniques that specifically achieve Initial Access. This can lead to the execution of malicious code, such as code that establishes persistence, steals data, or mines cryptocurrency.(Citation: Datadog Security Labs Malicious PyPi Packages 2024)(Citation: Fortinet Malicious NPM Packages 2023) In some cases, threat actors may compromise and backdoor existing popular libraries (i.e., [Compromise Software Dependencies and Development Tools](https://attack.mitre.org/techniques/T1195/001)). Alternatively, they may create entirely new packages and leverage behaviors such as typosquatting to encourage users to install them.
