Helpful utilities dealing with access token based authentication, switching from Azto AzureADand az cliinterfaces, easy to use pre-made attacks such as Runbook-based command execution and more. The Most Valuable CmdletsThis toolkit brings lots of various cmdlets. This section highlights the most important & useful ones.

Typical Red Team / audit workflow starting with stolen credentials can be summarised as follows: Credentials Stolen -> Authenticate to Azure/AzureAD -> find whether they're valid -> find out what you can do with them The below cmdlets are precisely suited to help you follow this sequence:

1. Connect-ART- Offers various means to authenticate to Azure - credentials, PSCredential, token

2. Connect-ARTAD- Offers various means to authenticate to Azure AD - credentials, PSCredential, token

3. Get-ARTWhoami- When you authenticate - run this to check whoami and validate your access

4. Get-ARTAccess- Then, when you know you have access - find out what you can do & what's possible by performing Azure situational awareness

5. Get-ARTADAccess- Similarly you can find out what you can do scoped to Azure AD. Use CasesCmdlets implemented in this module came helpful in following use & attack scenarios:

* Juggling with access tokens from Azto AzureADand back again.
* Nicely print authentication context (aka whoami) in Az, AzureAD, Microsoft.Graphand az cliat the same time
* Display available permissions granted to the user on a target Azure VM
* Display accessible Azure Resources along with permissions we have against them
* Easily read all accessible Azure Key Vault secrets
* Authenticate as a Service Principal to leverage Privileged Role Administrator role assigned to that Service Principal
* Execute attack against Azure Automation via malicious Runbook InstallationThis module depends on Powershell Azand AzureADmodules pre-installed. Microsoft.Graphand az cliare optional but nonetheless really useful. Before one starts crafting around Azure, following commands may be used to prepare one's offensive environment:

Install-Module Az -Force -Confirm -AllowClobber -Scope CurrentUser
Install-Module AzureAD -Force -Confirm -AllowClobber -Scope CurrentUser
Install-Module Microsoft.Graph -Force -Confirm -AllowClobber -Scope CurrentUser # OPTIONAL
Install-Module MSOnline -Force -Confirm -AllowClobber -Scope CurrentUser        # OPTIONAL
Install-Module AzureADPreview -Force -Confirm -AllowClobber -Scope CurrentUser  # OPTIONAL
Install-Module AADInternals -Force -Confirm -AllowClobber -Scope CurrentUser    # OPTIONAL

Import-Module Az
Import-Module AzureAD

Even though only first two modules are required by AzureRT, its good to have others pre-installed too.

Then to load this module, simply type: PS> . .\AzureRT.ps1 And you're good to go.

Or you can let AzureRT to install and import all the dependencies:

PS> . .\AzureRT.ps1
PS> Import-ARTModules

Batteries IncludedThe module will be gradually receiving next tools and utilities, naturally categorised onto subsequent kill chain phases.

Every cmdlet has a nice help message detailing parameters, des[...]

cription and example usage: PS C:\> Get-Help Connect-ART Currently, following utilities are included: Authentication & Token mechanics* Get-ARTWhoami- Displays and validates our authentication context on Azure, AzureAD, Microsoft.Graphand on AZ CLIinterfaces.

* Connect-ART- Invokes Connect-AzAccountto authenticate current session to the Azure Portal via provided Access Token or credentials. Skips the burden of providing Tenant ID and Account ID by automatically extracting those from provided Token.

* Connect-ARTAD- Invokes Connect-AzureAD(and optionally Connect-MgGraph) to authenticate current session to the Azure Active Directory via provided Access Token or credentials. Skips the burden of providing Tenant ID and Account ID by automatically extracting those from provided Token.

* Connect-ARTADServicePrincipal- Invokes Connect-AzAccountto authenticate current session to the Azure Portal via provided Access Token or credentials. Skips the burden of providing Tenant ID and Account ID by automatically extracting those from provided Token. Then it creates self-signed PFX certificate and associates it with Service Principal for authentication. Afterwards, authenticates as that Service Principal to AzureAD and deassociates that certificate to cleanup

* Get-ARTAccessTokenAzCli- Acquires access token from az cli, via az account get-access-token* Get-ARTAccessTokenAz- Acquires access token from Az module, via Get-AzAccessToken.

* Get-ARTAccessTokenAzureAD- Gets an access token from Azure Active Directory. Authored by Simon Wahlin, @SimonWahlin * Get-ARTAccessTokenAzureADCached- Attempts to retrieve locally cached AzureAD access token (https://graph.microsoft.com), stored after Connect-AzureADoccurred.

* Remove-ARTServicePrincipalKey- Performs cleanup actions after running Connect-ARTADServicePrincipalRecon & Situational Awareness* Get-ARTAccess- Performs Azure Situational Awareness.

* Get-ARTADAccess- Performs Azure AD Situational Awareness.

* Get-ARTTenants- List Tenants available for the currently authenticated user (or the one based on supplied Access Token)

* Get-ARTDangerousPermissions- Analyzes accessible Azure Resources and associated permissions user has on them to find all the Dangerous ones that could be abused by an attacker.

* Get-ARTResource- Authenticates to the https://management.azure.com using provided Access Token and pulls accessible resources and permissions that token Owner have against them.

* Get-ARTRoleAssignment- Displays a bit easier to read representation of assigned Azure RBAC roles to the currently used Principal.

* Get-ARTADRoleAssignment- Displays Azure AD Role assignments on a current user or on all Azure AD users.

* Get-ARTADScopedRoleAssignment- Displays Azure AD Scoped Role assignments on a current user or on all Azure AD users, associated with Administrative Units

* Get-ARTRolePermissions- Displays all granted permissions on a specified Azure RBAC role.

* Get-ARTADRolePermissions- Displays all granted permissions on a specified Azure AD role.

* Get-ARTADDynamicGroups- Displays Azure AD Dynamic Groups along with their user Membership Rules, members count and current user membership status

* Get-ARTApplication- Lists Azure AD Enterprise Applications that current user is owner of (or all existing when -All used) along with their owners and Service Principals

* Get-ARTApplicationProxy- Lists Azure AD Enterprise Applications that have Application Proxy setup.

* Get-ARTApplicationProxyPrincipals- Displays users and groups ass[...]
