TokenTactics

Azure access tokens allow you to authenticate to certain endpoints as a user who signs in with a device code. Even if they used multi-factor authentication. 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 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 or MS Teams and read/send messages!
