Step-by-Step Guide: Installing Kali Linux on VirtualBox

What is Kali Linux?

Kali Linux is a Debian‑based Linux distribution designed for digital forensics and penetration testing, pre‑installed with hundreds of security tools such as Nmap, Burp Suite, Metasploit, Aircrack‑ng, and many others.

Downloading the ISO

The latest 64‑bit ISO can be downloaded from the official Kali website.

Setting Up VirtualBox

Create a new virtual machine in VirtualBox, choose Linux as the type and Debian (64‑bit) as the version. Configure memory, virtual hard‑disk size, and other basic settings. After the VM is created, open its Storage settings and attach the downloaded Kali ISO as a virtual CD.

Installing Kali

Start the VM and select the Graphical install option. Follow the on‑screen prompts to choose language (Chinese Simplified or English), set up the keyboard, configure the network, and create a user. The installation process is largely automated and typically finishes within half an hour.

First Look at the System

After reboot, you are greeted by a clean login screen and a minimalist desktop. The start menu already contains dozens of pre‑installed penetration tools for vulnerability analysis, password cracking, wireless attacks, and packet sniffing. The desktop wallpaper is simple, and you can change it or switch to a Windows‑10‑like theme.

Important Warnings

Kali is not intended for everyday desktop use. It runs with root privileges by default, lacks the hardening of regular Linux distributions, and is meant as an offensive security platform. Misusing the tools can cause real damage and may lead to legal consequences; therefore, only use Kali in a controlled, lawful environment.
