o365chk.py

Simple Python script to check if there is an Office365 instance linked to a particular domain.

There are three possible results:

Unknown = No O365 instance for that domain
Federated = O365 is federated
Managed = O365 is managed directly by Microsoft

Installation and Usage

$ git clone https://github.com/nixintel/o365chk && cd o365chk

$ pip install -r requirements.txt

$ python3 o365chk.py -d example.com

Example Output

    $ python3 o365chk.py -d bbc.co.uk

    This domain is Federated
{
        "AuthNForwardType": 1,
        "AuthURL": "https://gateway.id.tools.bbc.co.uk/eiam/WSFederationServlet/metaAlias/wsidp2?username=username%40bbc.co.uk&wa=wsignin1.0&wtrealm=urn%3afederation%3aMicrosoftOnline&wctx=",
        "CloudInstanceIssuerUri": "urn:federation:MicrosoftOnline",
        "CloudInstanceName": "microsoftonline.com",
        "DomainName": "bbc.co.uk",
        "FederationBrandName": "BBC",
        "FederationGlobalVersion": -1,
        "Login": "[email protected]",
        "NameSpaceType": "Federated",
        "State": 3,
        "UserState": 2
       }

Checking Multiple Domains

By default the script only checks for one domain. To query multiple domains from an input file run the multi.sh bash script with a file containing the domains as an argument.

Example format domains.txt:

example.org
somesite.net
targetdomain.com

To query all these domains at once:

$ ./multi.sh domains.txt
