MS-T801 - Storage account discovery
Attackers may execute active reconnaissance scans to gather storage account names that becomes a potential target. Active scans are those where the adversary probes victim infrastructure via network traffic, as opposed to other forms of reconnaissance that do not involve direct interaction.

MS-T826 - DNS/Passive DNS
Attackers may search for DNS data for valid storage account names that can become potential targets. Threat actors can query nameservers using brute-force technique to enumerate existing storage accounts in the wild, or search through centralized repositories of logged DNS query responses (known as passive DNS).

MS-T805 - Victim-owned websites
Attackers may look for storage accounts of a victim enterprise by searching its websites. Victim-owned website pages may be stored on a storage account or contain links to retrieve data stored in a storage account. The links contain the URL of the storage and provide an entry point into the account.

MS-T814 - Valid SAS token
A shared access signature (SAS) is a token, that is appended to the a uniform resource identifier (URI) for a storage resource, that grants restricted access rights over the associated resource in your storage account. Attackers may get a SAS token using one of the Credential Access techniques or during the reconnaissance process through social engineering.

MS-T815 - Valid shared key
Attackers may get a shared key using one of Credential Access techniques or capture one earlier in their reconnaissance process through social engineering to gain initial access. Adversaries may leverage keys left in source code or configuration files. Sophisticated attackers may also obtain keys from hosts (virtual machines) that have mounted File Share on their system (SMB). Shared key provides unrestricted permissions over all data plane operations.

MS-T817 - Anonymous public read access
Attackers may leverage publicly exposed storage accounts to list containers/blobs and their properties. Azure Storage supports optional anonymous public read access for containers and blobs. By default, anonymous access to your data is never permitted. Unless you explicitly enable anonymous access, all requests to a container and its blobs must be authorized. When you configure a container's public access level setting to permit anonymous access, clients can read data in that container without authorizing the request.

MS-T825 - SFTP credentials
Attackers may obtain and abuse credentials of an SFTP account as a means of gaining initial access. SFTP is a prevalent file transfer protocol between a client and a remote service. Once the user connects to the cloud storage service, the user can upload and download blobs and perform other operations that are supported by the protocol. SFTP connection requires SFTP accounts which are managed locally in the storage service instance, including credentials in a form of passwords or key-pairs.

MS-T827 - NFS access
Attackers may perform initial access to a storage account using NFS protocol where enabled. While access is restricted to a list of allowed virtual networks that are configured on the storage account firewall, connection via NFS protocol does not require authentication and can be performed by any source on the specified networks.

MS-T840 - Object replication
Attackers may set a replication policy between source and destination containers that asynchronously copies objects from source to destination. This feature can be maliciously misused in both directions. Outbound replication can serve as an exfiltration channel of customer data from the victim's container to an adversary's container. Inbound replication can be used to deliver malware from an adversary's container to a victim's container. After the policy is set, the attacker can operate on their container without accessing the victim container.

MS-T813 - Firewall and virtual networks configuratioin changes
Attackers may disable firewall protection or set additional firewall rules to masquerade their access channel. Azure Storage offers a set of built-in network access features. Administrators can leverage these capabilities to restrict access to storage resources. Restriction rules can operate at the IP level or VNet IDs. When network rules are configured, only requests originated from authorized subnets will be served.

MS-T808 - Role-based access control permission
Storage services offer built-in RBAC roles that encompass sets of permissions used to access different data types. Definition of custom roles is also supported. Upon assignment of an RBAC role to an identity object (like Azure AD security principal) the storage provider grants access to that security principal. Attackers may leverage the RBAC mechanism to ensure persistent access to their owned identity objects.

MS-T806 - Create SAS token
Attackers may create a high-privileged SAS token with long expiry to preserve valid credentials for a long period. The tokens are not monitored by storage accounts thus they cannot be revoked (except Service SAS) and it's not easy to determine whether there are valid tokens in the wild until they are used.

MS-T830 - Trusted Azure services
Attackers may configure the storage account firewall to allow access by trusted Azure services. Azure Storage provides a predefined list of trusted services. Any resource from that list that belongs to the same subscription as the storage account is allowed by the firewall even if there is no firewall rule that explicitly permits the source address of the resource.

MS-T829 - Trusted access based on a managed identity
Attackers may configure the storage account firewall to allow access by specific resource instances based on their system-assigned managed identity, regardless of their source address. The resource type can be chosen from a predefined list provided by Azure Storage, and the resource instance must be in the same tenant as the storage account. The RBAC permissions of the resource instance determine the types of operations that a resource instance can perform on storage account data.

MS-T810 - Disable audit logs

Cloud Shell is an interactive, authenticated, browser-accessible shell for managing cloud resources. It provides the flexibility of shell experience, either Bash or PowerShell. To support the Cloud Shell promise of being accessible from everywhere, Cloud Shell profiles and session history are saved on storage account. Attackers may leverage the legitimate use of Cloud Shell to impersonate account owners and potentially obtain additional secrets logged as part of session history.
