“The first step in pentesting is information gathering.”
I wrote a simple python script that could help with information gathering. It takes one input from the user, which is a website’s url or link. With that information the script can start with the information gathering process. It can get the website’s IP address, IP lookup, Geolocalisation, http header, a list of IP address, and finally scans the IP address for open ports.
