T1136.003 — Create Account: Cloud Account
Sub-technique of T1136 Create Account
Description
Adversaries may create a cloud account to maintain access to victim systems. With a sufficient level of access, such accounts may be used to establish secondary credentialed access that does not require persistent remote access tools to be deployed on the system.
In addition to user accounts, cloud accounts may be associated with services. Cloud providers handle the concept of service accounts in different ways. In Azure, service accounts include service principals and managed identities, which can be linked to various resources such as OAuth applications, serverless functions, and virtual machines in order to grant those resources permissions to perform various activities in the environment. In GCP, service accounts can also be linked to specific resources, as well as be impersonated by other accounts for Temporary Elevated Cloud Access. While AWS has no specific concept of service accounts, resources can be directly granted permission to assume roles.
Adversaries may create accounts that only have access to specific cloud services, which can reduce the chance of detection.
Once an adversary has created a cloud account, they can then manipulate that account to ensure persistence and allow access to additional resources - for example, by adding Additional Cloud Credentials or assigning Additional Cloud Roles.

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.
