O365
This module allows to enumerate users and bruteforce / spray passwords.
User enumeration
Several modes are available: office, oauth2 and OneDrive (not implemented yet). The office mode is recommended as no authentication is made. Oauth2 can retrieve additional information through AADSTS error code (MFA enable, locked account, disabled account)
Passwords bruteforce / spray
As for the user enumeration, two modes are available: oauth2 and autodiscover (not implemented yet). The Oauth2 is the recommended mode, it allows to get much information thanks to the AADSTS error code.
OWA
This module allows to enumerate users and bruteforce / spray passwords.
User enumeration
Enumeration is made with authentication requests. Authentication for a non-existent user will take longer than for a valid user. At first, the average response time for an invalid user will be calculated and then the response time for each authentication request will be compared.
Passwords bruteforce / spray
Please note that no account locking mechanism can be implemented because no information about it is returned.
