If you're interested in hacking—whether for cybersecurity, ethical hacking, or penetration testing—one of the first questions you might ask is:
"Which programming language should I learn first?"
The answer depends on what kind of hacking you want to do. Different languages serve different purposes in hacking, from automating tasks to exploiting vulnerabilities.
In this guide, we'll break down the best programming languages for hacking, explain why they're useful, and help you decide which one to start with.

Why Do Hackers Need Programming Skills?
Before diving into languages, let's understand why programming is essential for hacking:
- Automation – Hackers write scripts to automate repetitive tasks (like scanning networks or cracking passwords).
- Exploit Development – To find and exploit vulnerabilities, you need to write or modify code.
- Reverse Engineering – Understanding malware or proprietary software requires reading and modifying code.
- Tool Customization – Many hacking tools (like Metasploit) allow customization through scripting.
- Creating Your Own Tools – Sometimes, existing tools aren't enough, so hackers build their own.
Now, let's explore the best programming languages for hacking.
Best Programming Languages for Hacking (Ranked by Importance)
1. Python – The Best Language for Beginners
Why Python?
- Easy to Learn: Python has simple, readable syntax, making it perfect for beginners.
- Powerful Libraries: It has libraries for almost everything (networking, cryptography, exploit development).
- Used in Cybersecurity Tools: Many hacking tools (like Metasploit, Burp Suite) support Python scripting.
What Can You Do with Python in Hacking?
- Write scripts to automate attacks (e.g., brute-force attacks, network scanning).
- Develop exploits (using frameworks like pwntools).
- Interact with web APIs (for scraping or attacking web apps).
- Analyze malware and reverse-engineer software.
Example Python Hacking Script (Simple Port Scanner)
import socket
target = "example.com"
ports = [21, 22, 80, 443]
for port in ports:
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(1)
result = sock.connect_ex((target, port))
if result == 0:
print(f"Port {port} is open!")
sock.close()
This script checks if common ports (21, 22, 80, 443) are open on a target website.
2. Bash Scripting – Essential for Linux-Based Hacking
Why Bash?
- Linux Dominance: Most hacking tools run on Linux (Kali Linux, Parrot OS).
- Automation: Bash helps automate command-line tasks.
- Penetration Testing: Many exploits involve running Bash commands.
What Can You Do with Bash?
- Automate repetitive terminal commands.
- Chain multiple hacking tools together.
- Write simple scripts for privilege escalation.
Example Bash Script (Automated NMAP Scan)
#!/bin/bash echo "Enter target IP:" read target nmap -sV -A -T4 $target
This script runs an aggressive NMAP scan on a target IP.
3. JavaScript – For Web Hacking
Why JavaScript?
- Web Exploits: Many web attacks (XSS, CSRF) rely on JavaScript.
- Node.js: Allows server-side hacking and API manipulation.
- Browser Exploits: Understanding JS helps in bypassing security controls.
What Can You Do with JavaScript?
- Perform Cross-Site Scripting (XSS) attacks.
- Manipulate web applications dynamically.
- Analyze and bypass client-side security.
Example JavaScript (Simple XSS Payload)
<script>alert("Hacked!")</script>
This is a basic XSS payload that executes when injected into a vulnerable website.
4. SQL – For Database Hacking
Why SQL?
- Database Exploits: SQL Injection (SQLi) is a major web vulnerability.
- Data Extraction: Hackers use SQL to steal or manipulate database info.
What Can You Do with SQL?
- Perform SQL Injection attacks.
- Extract sensitive data (usernames, passwords).
- Bypass authentication systems.
Example SQL Injection Attack
' OR '1'='1' --
This classic SQLi payload bypasses login forms by tricking the database.
5. C/C++ – For Exploit Development & Reverse Engineering
Why C/C++?
- Low-Level Access: Essential for writing exploits (buffer overflows, rootkits).
- Malware Analysis: Many malware samples are written in C/C++.
- Performance: Used in writing fast, efficient hacking tools.
What Can You Do with C/C++?
- Develop custom exploits.
- Reverse-engineer binaries.
- Write shellcode for advanced attacks.
Example C Code (Buffer Overflow Concept)
#include <stdio.h>
#include <string.h>
void vulnerable_function(char *input) {
char buffer[10];
strcpy(buffer, input); // Potential buffer overflow!
}
int main() {
char payload[20] = "AAAAAAAAAAAAAAAAAAAA";
vulnerable_function(payload);
return 0;
}
This code demonstrates a simple buffer overflow vulnerability.
6. PHP – For Web Application Hacking
Why PHP?
- Web Backends: Many websites use PHP (WordPress, Joomla).
- Finding Vulnerabilities: Understanding PHP helps in finding flaws.
What Can You Do with PHP?
- Find vulnerabilities in PHP-based websites.
- Write custom web shells for post-exploitation.
Example PHP Exploit (Simple Web Shell)
<?php system($_GET['cmd']); ?>
This PHP code allows executing system commands via URL parameters (dangerous if uploaded to a server).
7. Ruby – For Exploit Writing
Why Ruby?
- Metasploit Framework: Many exploits in Metasploit are written in Ruby.
- Readable Syntax: Easier to write and understand exploits.
What Can You Do with Ruby?
- Write custom Metasploit modules.
- Automate penetration testing tasks.
Example Ruby Script (Metasploit Module Skeleton)
require 'msf/core'
class MetasploitModule < Msf::Exploit::Remote
def initialize(info = {})
super(update_info(info,
'Name' => 'Example Exploit',
'Description' => 'This is a sample exploit module',
'Payload' => { 'BadChars' => "\x00" }
))
end
def exploit
# Exploit code here
end
end
This is a basic structure for a Metasploit exploit module.
Which Language Should You Learn First?
For Beginners:
✅ Python (Best for automation, easy to learn)
✅ Bash (Essential for Linux hacking)
For Web Hackers:
✅ JavaScript (XSS, CSRF, web exploits)
✅ SQL (Database hacking, SQL Injection)
✅ PHP (Web app security testing)
For Advanced Hackers:
✅ C/C++ (Exploit development, malware analysis)
✅ Ruby (Writing Metasploit exploits)
Final Advice
- Start with Python – It's versatile and beginner-friendly.
- Learn Bash – Essential for working in Linux.
- Explore Web Languages (JavaScript, SQL, PHP) if interested in web hacking.
- Move to C/C++ if you want to dive into exploit development.
Conclusion
There's no single "best" language for hacking—it depends on your goals. Python is the best starting point, but learning multiple languages will make you a more versatile hacker.
What's next?
- Practice coding daily.
- Try Capture The Flag (CTF) challenges.
- Contribute to open-source security projects.
Happy hacking! 🚀
