SQL Injection: Unlocking Databases, One Query at a Time

In the realm of cybersecurity, few attack techniques have remained as relevant and impactful as SQL Injection (SQLi). For red team operators, it’s a go-to exploit that leverages poorly secured web applications to gain unauthorized access, steal sensitive information, and escalate privileges. SQL Injection isn’t just a vulnerability; it’s a reminder of the critical importance of secure coding practices. Let’s delve into this powerful attack vector to understand how it works, the types of SQLi, and advanced techniques for exploitation.

What Is SQL Injection?

SQL Injection is a code injection technique that manipulates a web application’s database query by injecting malicious SQL statements into user input fields. This happens when an application does not properly sanitize or validate user inputs before processing them in a database query. The consequences can range from data leaks to complete control over the backend database.

Imagine walking into a secure building with a fake keycard that opens every door. SQL Injection is that keycard, but for databases.
