When you ask “What is Linux?”, think of it as the backbone of everything from smartphones and routers to supercomputers and cloud platforms.

🔓 Why Do Hackers Use Linux? linux basics for hackers

Let’s get real — if you’re getting into ethical hacking, you must understand why Linux is the #1 choice among hackers and pentesters:

1. Control and Transparency: linux basics for hackers

Linux allows you to see how everything works — from boot processes to packet flow. It teaches you to think like a hacker.

2. Command-Line Interface (CLI) Superpower

Unlike point-and-click OSs, Linux’s terminal lets you run powerful scripts, automate tasks, and dig deep into system behavior. This is vital for reconnaissance, exploitation, and post-exploitation tasks.

3. Security-First Tools and Architecture

Distributions like Kali Linux, Parrot OS, and BackBox are made for penetration testing. They include tools like:

• nmap for network scanning
• metasploit for exploitation
• hydra for brute force attacks
• aircrack-ng for Wi-Fi hacking

4. Custom Environments for Pentesting

Linux lets you create custom hacking environments through VM snapshots, Bash scripts, and secure sandboxes.
