Local Account

ATT&CK ID: T1136.001
Permissions Required: Administrator | SYSTEM
Description
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. With a sufficient level of access, the net user /add command can be used to create a local account. On macOS systems the dscl -create command can be used to create a local account.
Such accounts may be used to establish secondary credentialed access that do not require persistent remote access tools to be deployed on the system.
