GetNPUser does the asreproast thing, GetUserSPN is kerberoasting, it request service tickets for accounts(usually service accounts) that has SPN set. There's actually no good reason when to run the GetNPUser script cuz we usually don't have enough privilege before an initial foothold to see which users have "do not require Kerberos pre auth" option enabled ( this is not practical in real world as a sysadmin would never do it ) so in ctfs if you have a list of usernames and password spraying didn't work always give it a try and GetUserSPNs usually work with service accounts, it's more of a post Exploitation script.

Amazing guide, thank you. Is there a specific reason psexec is used at the end to pass the hash for the administrator user? Can evil-winrm be used to perform the same thing? ie get shell access to the administrator user. Just trying to understand everything and the tools used for different use cases. Cheers !

You can add a -B 2 to your ./hashcat --example-hashes | grep asrep to get the mode printed right there. Also i think you skipped showing how you get from the user called svc_loadmanager to it being called svc_loanmgr, that was a weird one.

@kam7621 Ай бұрын
This part looked to me like bullshit as well. The most legit way of doing that would be listing users with net user /domain and dir C:\Users in the results there is svc_loanmgr so it could ring the bell because it's similar to svc_loanmanager.

so if "nmap scans the most common 1000 ports for each protocol by default"... does that mean, say, the range for tcp would exclude ports specified for other protocols and therefore exceed the first 1000? My scan didn't bring up 3268, but yours did. same flags.
@ippsec 8 ай бұрын
I am not positive. I would try reverting the machine and trying again. I believe 3268 is LDAP over SSL, which requires a certificate. This is a very old machine so it is possible the certificate expired and then the service which listens on 3268 no longer launches. You could verify this by using like nc -zv 3268 and seeing if it says open.

Why was it that we had the password in plaintext for SVC_loanmanager. I understand the credentials were saved, but why and where? Great video by the way, thanks a lot!
@kegnsec 3 жыл бұрын
They're stored in the registry. If you wanted to get them without winpeas, you can grab them with 'reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon" '.
@Naveenkumar-pr2fe 3 жыл бұрын
@TheSurvivor4 Those credentials are stored in an autologon mechanism. Instead of the user enter their name and password everytime in the login prompt the autologin mechanism makes it easy by grabbing the cred from registry and let you in. So there is no need to enter name and pass each and every time. The password is in plaintext because the author of the machine wants us to know that storing a password by default config will be a security risk and it's the way to get on to the svc_loanmgr user
@TheSurvivor4 3 жыл бұрын
Thank you both very much for the explanation. Greatly appreciated. Is there a way to secure a system and still use the auto-login functionality without having to use the plain-text approach?

@@TheSurvivor4 Important The autologon feature is provided as a convenience. However, this feature may be a security risk. If you set a computer for autologon, anyone who can physically obtain access to the computer can gain access to all the computer's contents, including any networks it is connected to. Additionally, when autologon is turned on, the password is stored in the registry in plain text. support.microsoft.com/en-us/help/324737/how-to-turn-on-automatic-logon-in-windows
