T1136.001 Local Account Mappings

Adversaries may create a local account to maintain access to victim systems. Local accounts are those configured by an organization for use by users, remote support, services, or for administration on a single system or service.

For example, with a sufficient level of access, the Windows <code>net user /add</code> command can be used to create a local account. On macOS systems the <code>dscl -create</code> command can be used to create a local account. Local accounts may also be added to network devices, often via common Network Device CLI commands such as <code>username</code>, or to Kubernetes clusters using the kubectl utility.(Citation: cisco_username_cmd)(Citation: Kubernetes Service Accounts Security)

Such accounts may be used to establish secondary credentialed access that do not require persistent remote access tools to be deployed on the system.
