Task: hard Windows AD domain controller (codeby.cdb / HELIX) whose foothold is an open NFS export rather than AD enumeration. Solution: mount /it_stuff to harvest user valentin.badanov plus a leaked password list, brute-force it, abuse ForceChangePassword over valentin.badanov_adm, then abuse Kerberos constrained delegation (S4U) to impersonate Administrator and read the C$ flags — entirely with impacket from macOS.
