In this challenge, you'll be tasked with creating a new user account named 'bob' on a Kali Linux system. This is a fundamental skill for cybersecurity professionals, allowing them to manage user access and permissions. The challenge involves using the `adduser` command to create the 'bob' user, setting a password, and skipping the optional information prompts. Successful completion will be verified by confirming the user's existence using the `id bob` command and checking the command history for the `adduser bob` command.

In this challenge, you'll step into the role of a cybersecurity intern tasked with auditing a server's security. Your objective is to utilize Nmap to identify open ports on a target system with the IP address `172.17.0.1`. Save the scan results to `/root/open_ports.txt`.

In this lab, explore reconnaissance techniques using Kali Linux with a focus on network scanning and DNS querying. Learn to identify open ports and services with Nmap, enumerate services using scripts, query DNS records with dnsrecon, and save output for analysis, all within a secure LabEx VM environment.

In this lab, you will learn how to determine if your Linux system is 32-bit or 64-bit using command-line tools like `uname -m` and `arch`. You will execute these commands, interpret their output, and inspect binary files to understand your system's architecture and ensure software compatibility.

In this lab, explore password cracking with Kali Linux using John the Ripper on the LabEx VM. Learn to crack Linux password hashes from /etc/shadow, use custom wordlists, compare with Hashcat, and save results. Perfect for beginners, this hands-on lab offers step-by-step guidance for penetration testing skills.

In this challenge, you'll take your first steps as a cybersecurity analyst by familiarizing yourself with Metasploit. Your objective is to start the Metasploit framework console. To complete this challenge, simply execute the `msfconsole` command in the terminal.

In this challenge, you will learn how to configure local storage on a Linux system by adding new partitions and logical volumes, as well as creating a swap space, without causing any data loss.
