SQL Injection Tester.

SQL Injection is a web security vulnerability that allows attackers to interfere with database queries by inserting malicious SQL code. This can lead to unauthorized data access, modification, or deletion of database content.

This tool simulates SQL injection attempts in a safe environment. It analyzes input for common SQL injection patterns and shows how the query would be constructed, without actually executing any database operations.

Common techniques include: Using OR statements to bypass authentication, UNION-based attacks to extract additional data, Comment insertion to modify query logic, and Blind SQL injection using boolean or time-based responses.

Key prevention methods include: Using parameterized queries or prepared statements, input validation, escaping special characters, implementing proper error handling, and using ORMs (Object-Relational Mappers) with built-in protection.

Databases become vulnerable when applications directly concatenate user input into SQL queries, don't properly validate or sanitize input, expose detailed error messages, or have excessive database privileges.
