It’s easy to overlook inheritance in Google Cloud. Inheritance can give compute engine instances unintentionally more privileges than intended. So when examining permissions for a resource, keep in mind that the resource might have permissions granted to them via inheritance in addition to the permissions they granted directly.

In the previous blog post, Lateral Movement in Google Cloud: Abusing the Infamous Default Service Account Misconfiguration, we reviewed some essential Google Cloud components to include service accounts, service account types, roles, and cloud API access scopes to understand how these components can be used to gain lateral movement capabilities.

Using the same components mentioned above and different enumeration processes, an attacker can detect which compute engine instances could expose the storage data in its Google Cloud project scope
