Actually, the real countermeasure to PTH is to disable NTLM auth and rely only on Kerberos (and then monitor NTLM as a very strong indicator that someone or something is attempting PTH)

Of course kerberos tickets can be abused too in a lot of fun ways, but on a modern network PTH is pretty much dead and a surefire way to raise a lot of alerts

(You are absolutely right that privileged accounts must never login on less privileged assets, however!)

Yeah...we just went through this process over here. I was more just making the point that "If its possible to use a system wrongly which undermines its security, it is already broken" isn't always true. I guess you could argue its NTLM there thats 'already broken', but the idea was more "SysAdmins are sometimes given red buttons to never press under any circumstances."
