T1136.003 Cloud Account
Adversaries may create a cloud account to maintain access to victim systems. With a sufficient level of access, such accounts may be used to establish secondary credentialed access that does not require persistent remote access tools to be deployed on the system.15234
Adversaries may create accounts that only have access to specific cloud services, which can reduce the chance of detection.
Once an adversary has created a cloud account, they can then manipulate that account to ensure persistence and allow access to additional resources - for example, by adding Additional Cloud Credentials or assigning Additional Cloud Roles.

Procedure Examples
ID | Name | Description |
---|---|---|
S0677 | AADInternals | AADInternals can create new Azure AD users.6 |
G0016 | APT29 | APT29 can create new users through Azure AD.7 |
G1004 | LAPSUS$ | LAPSUS$ has created global admin accounts in the targeted organization’s cloud instances to gain persistence.8 |
Mitigations
ID | Mitigation | Description |
---|---|---|
M1032 | Multi-factor Authentication | Use multi-factor authentication for user and privileged accounts. |
M1030 | Network Segmentation | Configure access controls and firewalls to limit access to critical systems and domain controllers. Most cloud environments support separate virtual private cloud (VPC) instances that enable further segmentation of cloud systems. |
M1026 | Privileged Account Management | Do not allow privileged accounts to be used for day-to-day operations that may expose them to potential adversaries on unprivileged systems. |
