Technical requirements
As previously mentioned, Kali Linux has been around for quite some time. Known previously as BackTrack, with releases from versions one to five, Kali Linux was first seen in 2015 and released as Kali 1.0. From 2016 onward, Kali was then named according to the year. So, for instance, at the time of writing this book, the version used is Kali 2022.3, released in August 2022.
For those running older versions of Kali Linux or purchasing this book at a later date when new versions of Kali Linux, such as 2023 and later, may be available, you can easily update your instance of Kali Linux by using the sudo apt-get update command, demonstrated later in the Updating Kali section.
