Name: Cloud Infrastructure Discovery |
Description: An adversary may attempt to discover infrastructure and resources that are available within an infrastructure-as-a-service (IaaS) environment. This includes compute service resources such as instances, virtual machines, and snapshots as well as resources of other services including the storage and database... |
Tactics: Discovery |
Platforms Affected: IaaS |
Detection Strategies: Establish centralized logging for the activity of cloud infrastructure components. Monitor logs for actions that could be taken to gather information about cloud infrastructure, including the use of discovery API calls by new or unexpected users and enumerations from unknown or malicious IP addres... |

Technique ID: T1538 |
Name: Cloud Service Dashboard |
Description: An adversary may use a cloud service dashboard GUI with stolen credentials to gain useful information from an operational cloud environment, such as specific services, resources, and features. For example, the GCP Command Center can be used to view all assets, findings of potential security risks, and to r... |
Tactics: Discovery |
Platforms Affected: Azure AD, Google Workspace, IaaS, Office 365 |
Detection Strategies: Monitor account activity logs to see actions performed and activity associated with the cloud service management console. Some cloud providers, such as AWS, provide distinct log events for login attempts to the management console. |

Technique ID: T1526 |
Name: Cloud Service Discovery |
Description: An adversary may attempt to enumerate the cloud services running on a system after gaining access. These methods can differ from platform-as-a-service (PaaS), to infrastructure-as-a-service (IaaS), or software-as-a-service (SaaS). Many services exist throughout the various cloud providers and can include C... |
Tactics: Discovery |
Platforms Affected: Azure AD, Google Workspace, IaaS, Office 365, SaaS |
Detection Strategies: Cloud service discovery techniques will likely occur throughout an operation where an adversary is targeting cloud-based systems and services.
