T1087.004 Cloud Account

Adversaries may attempt to get a listing of cloud accounts. Cloud accounts are those created and configured by an organization for use by users, remote support, services, or for administration of resources within a cloud service provider or SaaS application. With authenticated access there are several tools that can be used to find accounts. The <code>Get-MsolRoleMember</code> PowerShell cmdlet can be used to obtain account names given a role or permissions group in Office 365. The Azure CLI (AZ CLI) also provides an interface to obtain user accounts with authenticated access to a domain. The command <code>az ad user list</code> will list all users within a domain. The AWS command <code>aws iam list-users</code> may be used to obtain a list of users in the current account while <code>aws iam list-roles</code> can obtain IAM roles that have a specified path prefix. In GCP, <code>gcloud iam service-accounts list</code> and <code>gcloud projects get-iam-policy</code> may be used to obtain a listing of service accounts and users in a project.
