T1136.001 — Create Account: Local Account
Sub-technique of T1136 Create Account
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.
For example, with a sufficient level of access, the Windows net user /add command can be used to create a local account. In Linux, the `useradd` command can be used, while on macOS systems, the dscl -create command can be used. Local accounts may also be added to network devices, often via common Network Device CLI commands such as username, to ESXi servers via `esxcli system account add`, or to Kubernetes clusters using the `kubectl` utility.
Adversaries may also create new local accounts on network firewall management consoles – for example, by exploiting a vulnerable firewall management system, threat actors may be able to establish super-admin accounts that could be used to modify firewall rules and gain further access to the network.
Such accounts may be used to establish secondary credentialed access that do not require persistent remote access tools to be deployed on the system.

This project's own SigmaHQ-derived detection pipeline tags every compiled rule with the ATT&CK technique(s) it maps to -- if a rule in your install covers this technique, it shows up automatically on your own Grafana Alerts dashboard's "Top ATT&CK Techniques" panel, no lookup needed. This page exists so a click from there always lands here on easysiem.com, not on attack.mitre.org.
