 Hello, this is another Mimikatz video and I want to show the skeleton command. The skeleton command uses skeleton keys. Skeleton key is keys used by locksmiths that can open many locks. So the ID here is on this domain controller and because this works only on domain controllers is that Mimikatz patches the code of the domain controller that does the password verification so that you can use one password to login to all accounts. So let me show you first here when I log on to this machine. So I have the administrator password here on this domain controller and I type the skeleton key password first to show you that it doesn't work. So this is Mimikatz. That's the password for the skeleton function. And if I use that password and it doesn't work, this is not the correct password. The correct password here is password like this, a complex password. Now I log on and then I'm going to use Mimikatz to inject the code for a skeleton key. So I run Mimikatz as an administrator. I enable the debug privilege because we need that to access the LSA process and then I issue the skeleton command like this. And now so the code of Active Directory here, the domain controller has been patched into memory so that when I type the password now Mimikatz, when I log on with any account that I will be granted access. So I can close Mimikatz and I can sign out like this and now I can type Mimikatz as a password. You can see here and I can log on with this password like this. So that is the skeleton password in French, the Passpartout. And if I log out and I log in with the actual password, this of course works too. Password of course I can log on with that one. The skeleton key installs a backdoor into memory and it is only into memory because if we reboot the domain controller then this code is gone and we can no longer use this. So let me reboot this. Let's say that it's an unplanned reboot. Okay, we reboot it and now we try to log in with Mimikatz as passwords. This no longer works because that code for the skeleton key is no longer into memory.
