APT_Kerberos

KDC

---

Nmap discovered a KDC service on the target IPv6 port 88 and 464 The running service is Microsoft Windows Kerberos

While I do not know the naming convention that the target domain uses, I will attempt to enumerate usernames as much as possible by brute-forcing the KDC For efficiency, I will get that running in the background while enumerating other services
