Axlle_Kerberos

Kerberos

---

Nmap discovered a KDC service on the target ports 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

I had kerbrute running in the background for a while and found 2 valid domain users;

• administrator
• mainframe (machine account)
