Description

This will alert when a user consents to provide a previously-unknown Azure application with the same OAuth permissions used by the FireEye PwnAuth toolkit (https://github.com/fireeye/PwnAuth). The default permissions/scope for the PwnAuth toolkit are user.read, offline_access, mail.readwrite, mail.send, and files.read.all. Consent to applications with these permissions should be rare, especially as the knownApplications list is expanded. Public contributions to expand this filter are welcome!
