A simple script to create a netcat reverse shell. For Red Teamers - you can auto_increment the listener port by setting a flag to true in payload.txt.  netcat.exe is not included and must be sourced elsewhere.

# Title: RAZ_ReverseShell
# Author: RalphyZ
# Version: 1.0
# Target: Windows 7+
# Dependencies: The following files must exist in the switch folder:
# nc.exe - Windows binary for netcat with the -e flag
# listener_port.txt - The Port number for the netcat listener
# listener_ip.txt - The IP Address for the netcat listener
#
# Description: Executes a netcat reverse cmd shell at a given IP and Port
# Intentionally, this script leaves a trace in the Run Box
#
# Colors:
# Green.....................Working
# White.....................Completed without error
# White (blinking)..........Incrementing the port in listener_port.txt
# Blue (blinking)...........listener_port.txt was not found
# Light-Blue (blinking).....listener_ip.txt was not found
# Amber (blinking)..........nc.exe was not found
# Change this if you want to enable auto_increment of the netcat port
# If true, the port number is increased by 1 everytime the script runs
# This is good for Red Teams doing PenTesting on multiple computers
