It is capable of a significant amount of information gathering about a prospective target in a single sweep of the domain.
There is a community edition built into our Kali Linux that allows us 12 scans without purchasing Maltego. In this tutorial, we will be using an active tool called Maltego, developed by Paterva, that can do many of these tasks with one simple scan. In previous guides, I have demonstrated multiple ways to perform reconnaissance including passive recon with Netcraft, active recon with Nmap or hping3, recon by exploiting DNS or SNMP, and many others. Without doing reconnaissance, you will likely be wasting your time and energy as well as risking your freedom. Before we attempt to exploit any target, it is wise to do proper reconnaissance.
