T1585.003 Cloud Accounts

Adversaries may create accounts with cloud providers that can be used during targeting. Adversaries can use cloud accounts to further their operations, including leveraging cloud storage services such as Dropbox, MEGA, Microsoft OneDrive, or AWS S3 buckets for Exfiltration to Cloud Storage or to Upload Tools. Cloud accounts can also be used in the acquisition of infrastructure, such as Virtual Private Servers or Serverless infrastructure. Establishing cloud accounts may allow adversaries to develop sophisticated capabilities without managing their own servers.(Citation: Awake Security C2 Cloud)

Creating Cloud Accounts may also require adversaries to establish Email Accounts to register with the cloud provider.

Entra ID's continuous access evaluation is a security control implemented by enabling services to subscribe to critical Microsoft Entra events. Those events can then be evaluated and enforced near real time. This process enables tenant users lose access to organizational SharePoint Online files, email, calendar, or tasks, and Teams from Microsoft 365 client apps within minutes after a critical event is detected.
