SMB


Nmap discovered that Windows directory service is running on the target port 445

Smbclient


┌──(kali㉿kali)-[~/archive/htb/labs/silo]
└─$ smbclient -L //$IP/
Password for [WORKGROUP\kali]:
session setup failed: NT_STATUS_ACCESS_DENIED

I am unable to start a NULL session in the target SMB server. Anonymous login is NOT allowed

There is nothing that I can do here without a valid credential.
