Azure JSON Web Token (“JWT”)Token Manipulation Toolset

Azure JWT’s allow you to authenticate to certain endpoints as the user who signed in with the device code. Even if they used multi-factor authentication. Once you have a user’s JWT, 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 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, switch to an Outlook token and read/send emails!

There are some example requests to endpoints in the resources folder.

You may also use these tokens with AAD Internals as well.

Usage

Generate Device Code

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!
