For those unaware, Kali Linux is one of the best Linux distros for hackers, pen-tester, and security researchers due to the fact that most of the hacking tools that are available online are built-in this Linux Distro. According to Offensive Security, the latest build of Kali Linux takes advantage of everything the Pi 4 has to offer. Kali Linux for Raspberry Pi 4 will benefit from Kali Linux support complete with on-board Wi-Fi monitor mode and frame injection support.
