Like that. And that probably just screwed up one of both my copies actually. Um I can kill that. And we will kill this.

And you actually never need to get on to this box. Um, this does speed things up and we're going to go over that.

Right. So, this was that. So, we could put this to a file and then see if we can just um execute the file and see if we get a shell back. That looks fine to me. We have file colon double slash and C colon program data doesn't have any typos. Rev.exe. Yeah, that all looks fine. Um maybe this extra line break is causing ... | 4,705.12 | 0 | {

Okay. So this piece up here, this is all optional. Um this is just so we can do the DNS request really quickly, right? Um what I showed earlier is when we did that TCP dump um we do see the server reaching out over IPv6 link local address that's the FE81s and it's asking for WPAD and because it's unconstrained delegati... | 4,798.48 | 0 | {

so we won't be able to talk to LDAP secure which means we can't use NLM relay to create the machine account for us. So before we do that we'll just have to specify the machine account.

This is it, right? So, we're pretty much going to be following their post. Um, but right here where they're doing NLM relay X, they're going into LDAP S. That isn't configured for this box, so we won't be able to do that. And that's why we're going to have to do this next step of adding the computer, right? And it talk... | 4,918.96 | 0 | {

Yeah. Right here. So if LDAPS s is not properly configured the attack will fail, right? Um we can get around that by just creating the machine account u beforehand. And the whole reason we need a machine account is um we just need to know the password of the machine account so we can create our own tickets. So let's go... | 4,957.6 | 0 | {

This is going to be a part of impact. We'll do computer name is IPSC. computer pass is going to be please subscribe the escalate oh that's going to be part of NLM relay um computer pass the DC host is DC University HDB and then we need to do credentials so we'll do university waO and then we got to get the password thi... | 4,985.6 | 0 | {

And hold on. I'm just going to get this there. Okay. So, NLM relay, uh, we need to do -6 because we want to do IPv6. Then the target is going to be LDAP 192.16899.1. Then we want delegate access.

Uh I'm not in power shell. Um sc.exe exe query paste. Uh whatever shell died. That sucks. Um let's get it again. And we'll have to rename this. I probably should just put this in burpswuite.
