Query: detect 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: T1674 Input Injection. Tactics: execution. Description: Adversaries may simulate keystrokes on a victim’s computer by various means to perform any type of action on behalf of the user, such as launching the command interpreter using keyboard shortcuts, typing an inline script to be executed, or interacting directly with a GUI-based application. These actions can be preprogrammed into adversary tooling or executed through physical devices such as Human Interface Devices (HIDs). For example, adversaries have used tooling that monitors the Windows message loop to detect when a user visits bank-specific URLs. If detected, the tool then simulates keystrokes to open the developer console or select the address bar, pastes malicious JavaScript from the clipboard, and executes it - enabling manipulation of content within the browser, such as replacing bank account numbers during transactions.(Citation: BleepingComputer BackSwap)(Citation: welivesecurity BackSwap) Adversaries have also used malicious USB devices to emulate keystrokes that launch PowerShell, leading to the download and execution of malware from adversary-controlled servers.(Citation: BleepingComputer USB)
