Kali Linux is known as one of the best hacking distributions, providing an entire arsenal of penetration testing tools. The developers recently released Kali Linux 2016.2, which solidified their efforts in making it a rolling distribution. Different desktop environments have been released alongside GNOME in this release, such as e17, LXDE, Xfce, MATE, and KDE. Kali Linux will be kept updated with the latest improvements and tools by weekly updated ISOs. For the purposes of this book, we will be using Kali Linux 2016.2 with GNOME as our development environment for many of the scanning scripts that will be discussed throughout this book.
