# Pass The Hash

## Overview

* Pass-the-Hash uses an NTLM hash to authenticate without knowing the plaintext password
* Works with NTLM authentication — does NOT work with Kerberos alone

## UAC Limitation

* Registry key: `HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\LocalAccountTokenFilterPolicy`
* Value `0` = only RID-500 (built-in Administrator) can PtH remotely
* Value `1` = all local admins can PtH
