📜 Hacking Tutorial 3: Basic SQL Injection Attack

SQL Injection is one of the most common vulnerabilities in web applications. It involves inserting malicious SQL code into a query to manipulate the database. Learn how it works below (for educational purposes only)! 🔐


Step-by-Step Guide

1. 🔍 Find a Vulnerable Website
- Look for websites that use input forms (like login pages or search bars).
- Test if the input is vulnerable by entering a single quote (') and observing the response.
- If you see errors like SQL syntax error, it might be vulnerable.

2. 📋 Test for SQL Injection
- Try injecting basic payloads:
- ' OR '1'='1' -- (bypass login pages)
- UNION SELECT null, table_name FROM information_schema.tables -- (list database tables)

3. 📂 Extract Data
- After identifying the vulnerability, modify the query to retrieve sensitive data:
- Example: UNION SELECT username, password FROM users --

4. ⚙️ Tools to Automate
- Use tools like sqlmap to automate the process.
