Description
The following analytic identifies the creation of a new Azure Automation account within an Azure tenant. Azure Automation is a cloud-based automation platform that allows administrators to automate Azure management tasks and orchestrate actions across external systems within Azure using PowerShell and Python. Azure Automation can also be configured to automate tasks on on premise infrastructure using a component called a Hybrid Runbook Worker. Automation accounts serve as a container to isolate Automation resources, runbooks, assets, and configurations from the resources of other accounts. They allow administrators to separate resources into logical environments or delegated responsibilities. Adversaries or red teams who have obtained privileged access to an Azure tenant may create an Azure Automation account with elevated privileges to maintain persistence in the Azure tenant. A malicious Automation Runbook can be created to create Global Administrators in Azure AD, execute code on VMs, etc.
