Note that this investigation is per app depending on the number of apps, this could take quite some time.įor new apps, you also have some options in AAD. This will show you both admin and user consent, the specific permissions, and which API(s) the app is accessing. Pick an application, and in the Security section, click Permissions. To see what's already in your business, go to the AAD Portal and click Enterprise applications.

Finally, you'll need to define corporate policy around these apps and then define guardrails using AAD, and if you have access to it, MCAS. If you think it must be hard to create fake apps and publish them, here's an open-source toolkit to help you get started.Īpart from training your users (if you allow them to consent to apps, see below) and training your administrators, an important step is investigating what applications are already in your directory. If you click the chevrons, an explanation of the requested permission is shown.Īnother step Microsoft has recently taken (November 8th, 2020) is barring end users from granting permissions to apps from non-verified publishers this should stop some of these attacks. This is what a sample admin consent grant screen looks like: In the second, a user grants permissions to their own data. In the first one, an administrator grants permissions to all the requested data in a tenant (make sure you train your administrators to understand the risks).

One is to verify the publishers of apps, which just confirms that the name of the publisher on the consent screen is indeed the company that made the app (no checking of the app code itself is performed). Microsoft has taken a few steps to remedy this situation. This might be fairly low-level, but even 'read all emails' can be pretty informative and a great starting point for further attacks and lateral movement. Even if your users use MFA for authentication (and they are-aren't they?) or reset their password, the attacker still has the access granted.
