Adversaries may use Valid Accounts to interact with remote systems using Windows Remote Management (WinRM). The adversary may then perform actions as the logged-on user.

WinRM is the name of both a Windows service and a protocol that allows a user to interact with a remote system (e.g., run an executable, modify the Registry, modify services).^[1] It may be called with the winrm command or by any number of programs such as PowerShell.^[2] WinRM can be used as a method of remotely interacting with Windows Management Instrumentation.^[3]
