T1069.003 Cloud Groups

Sub-technique of: T1069

High-Level Description

Adversaries may attempt to find cloud groups and permission settings. The knowledge of cloud permission groups can help adversaries determine the particular roles of users and groups within an environment, as well as which users are associated with a particular group.

With authenticated access there are several tools that can be used to find permissions groups. The Get-MsolRole PowerShell cmdlet can be used to obtain roles and permissions groups for Exchange and Office 365 accounts .

Azure CLI (AZ CLI) and the Google Cloud Identity Provider API also provide interfaces to obtain permissions groups. The command az ad user get-member-groups will list groups associated to a user account for Azure while the API endpoint GET https://cloudidentity.googleapis.com/v1/groups lists group resources available to a user for Google. In AWS, the commands ListRolePolicies and ListAttachedRolePolicies allow users to enumerate the policies attached to a role.

Adversaries may attempt to list ACLs for objects to determine the owner and other accounts with access to the object, for example, via the AWS GetBucketAcl API . Using this information an adversary can target accounts with permissions to a given object or leverage accounts they have already compromised to access the object.

Kill Chain Phase

Discovery (TA0007)

Platforms: SaaS, IaaS, Office Suite, Identity Provider

What to Check

Identify if Cloud Groups technique is applicable to target environment
Check SaaS systems for indicators of Cloud Groups
Check IaaS systems for indicators of Cloud Groups
Check Office Suite systems for indicators of Cloud Groups
Assess detection coverage (1 detection strategies)

How to Test

Manual Testing

Identify Attack Surface: Determine if the target environment is susceptible to Cloud Groups by examining the target platforms (SaaS, IaaS, Office Suite).
Assess Existing Defenses: Review whether mitigations for T1069.003 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.

Note: No Atomic Red Team tests available for this technique. See Atomic Red Team GitHub for updates.
