Mastering Kali Linux for Advanced Penetration Testing - Third Edition

Using scripts to combine masscan and nmap scans

The speed and reliability of masscan and nmap ability to enumerate in detail is a great combination to use in our goal-based penetration testing strategy. In this section, we will write a small script that can save time and provide more accurate results that can be used during exploitation and identifying the right vulnerabilities:

#!/bin/bashfunction helptext { 
  echo "enter the massnmap with the file input with list of IP address ranges" 
}if [ "$#" -ne 1 ]; then 
  echo  "Sorry cannot understand the command" 
  helptext>&2 
  exit 1 
elif [ ! -s $1 ]; then 
  echo "ooops it is empty" 
  helptext>&2 
  exit 1 
fi 
 
if [ "$(id -u)" != "0" ]; then 
  echo "I assume you are running as root" 
  helptext>&2 
  exit 1
