Gaining Domain Admin from Outside Active Directory

So, I am again up with a new article to share. It is a great write-up by Rob Brown. It is about penetration testing an Active Directory. This is useful for the penetration testers who are into internal penetration testing.

Do you have any more comments or concerns about it? Maybe some discussion questions?

Well, LAPS should solve this issue, right?

nvm: just for domain joined pc’s, my bad!

So would this work if the network was using 802.1x? Like if you needed a client certificate to get into the domain network?

That doesn’t have anything to do with the Local Administrator Account. Sure, the attacker would have a harder time getting into the network, but the actual vulnerability was that the not-joined PC did not have the GPO.
