A valid **TGT as any user** can be created **using the NTLM hash of the krbtgt AD account**. The advantage of forging a TGT instead of TGS is being **able to access any service** (or machine) in the domain and the impersonated user.
The **krbtgt** account **NTLM hash** can be **obtained** from the **lsass process** or from the **NTDS.dit file** of any DC in the domain. It is also possible to get that NTLM through a **DCsync attack**, which can be performed either with the [lsadump::dcsync](https://github.com/gentilkiwi/mimikatz/wiki/module-\~-lsadump) module of Mimikatz or the impacket example [secretsdump.py](https://github.com/SecureAuthCorp/impacket/blob/master/examples/secretsdump.py). Usually, **domain admin privileges or similar are required**, no matter what technique is used.
**Once** you have the **golden Ticket injected**, you can access the shared files **(C$)**, and execute services and WMI, so you could use **psexec** or **wmiexec** to obtain a shell (looks like yo can not get a shell via winrm).
