- name: Azure - Dump Azure Storage Account Objects via Azure CLI
  auto_generated_guid: 67374845-b4c8-4204-adcc-9b217b65d4f1
  description: |-
    This test dumps the content of the storage account objects present in the file defined in file_shares_csv_file_path. Note that this file is created in the atomic test T1619 "Azure - Enumerate Storage Account Objects via Key-based authentication using Azure CLI". When created manually, it must contain the columns "ResourceGroup","StorageAccountName", "FileShareName", "ContainerName", "BlobName".

    Requirements:
        - The test is intended to be executed in interactive mode (with -Interactive parameter) in order to complete the az login command when MFA is required.
        - The EntraID user must have the role "Storage Account Contributor", or a role with similar permissions.

    - iaas:azure
