Why do I need privileges for DNS exploitation?
If a user is a member of the DNSAdmins group, he can possibly load an arbitary DLL with the privileges of dns.exe that runs as SYSTEM. In case the DC serves a DNS, the user can escalate his privileges to DA. This exploitation process needs privileges to restart the DNS service to work.
Is it possible to privilege escalate to root domain of a forest?
If we manage to compromise a child domain of a forest and SID filtering isn’t enabled (most of the times is not), we can abuse it to privilege escalate to Domain Administrator of the root domain of the forest. This is possible because of the SID History field on a kerberos TGT ticket, that defines the “extra” security groups and privileges.
Are there any attacks to gain domain admin rights?
Benjamin Delpy (author of Mimikatz) wrote a MS14-068 exploit called Kekeo that improves on PyKEK. It finds & targets a vulnerable DC and works regardless if there are patched or 2012/2012R2 DCs in the site.
