Um, let's get target curb roast up and running first. So, we just Google this. We should go to a repo. And we also use this in the administrator machine. So, you can always go to that video if you're confused. But we can go in targeted Kerarost. And what is the command? So, we're going to do Python 3 uh targeted Keraro... | 1,761.559 | 0 | {

So this is going to be a encrypted blob of some stored credentials. If we try to use evil winterm to download it, I don't know exactly why it fails, but it failed and then crashed.

own help? It does. We can say u password. Then we need the um SID. So we can specify this. So, copy put the SID and then the password which was zero the one. I hope I typed that right. And what this will do is output the prekey file that's used to unlock. | 2,911.68 | 0 | {

Okay, hopefully this works. There we go. We are now logged in as Cer admin. So let's close these out and then we'll go back over to Blood Hound and see exactly what this user can do.

Okay, so we can see scenery has genetic right member of and add self to this delegated admin group. Delegated admins allowed to act as DC1.

So there's probably going to be two paths we can impersonate. We can either just impersonate DC01 itself and then do a DC sync because um if we impersonate the domain controller then we'll have access to do DC syncs. We can also probably go under the other administrator, right? If we look at the members of this, let's ... | 3,200.559 | 0 | {

So yeah, mark sensitive. I think if Elbian was mark sensitive, then we would not be able to perform this attack. But um you can never do it with just default administrator just because by default that's going to be a sensitive account. | 3,305.44 | 0 | {

Um maybe at the end of the video we will go explore that more to make sure what I'm saying is correct. Um because I'm not an expert when it comes to this type of stuff. I'm kind of just learning as I go. So what we want to do in order to abuse this attack is we have to have a account that has an SPN and we can use that... | 3,318.16 | 0 | {

The other thing we were curious about was service accounts. So we can see SQL CC and ARC is 1D1. So everything has unique passwords. There's no like password duplication between this.
