Terminology

Good Domains

We classify the following as "good domains":

dangerous Domains

We classify any registered autodiscover.* domain with a resolving A or CNAME record as "dangerous" due to the potential for abuse.

Benign Domains

We classify any .gov domain as benign due to their limited availability to the general public.

We also classify active domains presumed owned by Microsoft as benign. This is guesswork on our part, as Microsoft has not responded to repeated communication attempts. If you could get someone from Microsoft to pay attention to this we would love to hear from them and increase the accuracy of our data.

Passive Attack

Active/Downgrade/"The Ol' Switcheroo" Attack

As defined in the original presentation, the "Ol' Switcheroo" attack is a downgrade of more secure forms of authentication (OAuth, NTLM) to Basic Auth (effectively plaintext).

The following conditions are the minimum requirements for an active downgrade attack:

Go back

Registration Date

Where possible, we extracted the registration date of domains from WHOIS records. Those that were registered after the Guardicore publication (2021-09-22) get their threat score increased by one, whereas if they preexisted they have their threat score reduced by one.

Go back

Threat Score

The threat score is calculated based on the following factors and has a maximum value of 4 or 5 (depending on knowledge of registration date):

We have some heuristic measures to detect Microsoft owned domains which limit the threat score to 2/5

.gov domains are considered "benign" as their distribution should be limited.

The owner of this site has 2 registered domains that have had their scores capped at 2/5. These sites are serving XML redirects to non-resolving URLs as a potential mitigation from resolving up to autodiscover[.]gr, which at the time of writing is an active downgrade attack domain with a 5/5 threat score. Read more here

Domains that become known to be owned by Microsoft will be marked as benign as well.

Disclaimer

This threat assessment is generated in periodic intervals with automated tools and is bound to be imperfect. The data presented here is provided as-is.

Work in Progress

The current report is a work in progress. We are working to bring historical records into play and comparing current vs historical threats. We also believe we can root out some false positives when the root domain itself has an MX record (indicates private SLD). We will also provide some recommended actions that users can take, e.g. reporting the suspicious domains to the appropriate authorities.
