Information gathering and packet analysis tools
The first step in hacking into a network is to gather information about it. In many cases, connecting your laptop to the network and starting some basic tools will provide you with enough information to move forward. Let's start from the simple and obvious and continue with the tricky ones.
In this category, you have tools divided into four levels:
