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.[1]

Offense vs defense T1585.003
Is defensive coverage keeping up with adversary use? Eight counts, each ranked against all 697 ATT&CK techniques. Attack sits left, defense right, so a shape leaning left means adversaries are better documented here than defenders are equipped. Hover any spoke for its percentile and the share of techniques that have more. The timeline below shows when each side arrived.
Cloud Accounts detection strategy DET0846
MITRE names one behaviour worth catching for this technique and breaks it into 1 analytic, one per platform. Each carries the log sources it needs and the fields you tune per environment.
Detection of Cloud Accounts
1 platform
AN1978 · PRE
Much of this activity will take place outside the visibility of the target organization, making detection of this behavior difficult. Detection efforts may be focused on related stages of the adversary lifecycle, such as during exfiltration (ex: Transfer Data to Cloud Account).
Pre-compromiseM1056
This technique cannot be easily mitigated with preventive controls since it is based on behaviors performed outside of the scope of enterprise defenses and controls.
