Steal The Code: The SQL Injection Guide for the RoboWars
Chapter 3: The Art of Subverting the Database
As a member of the Robot Rebel Alliance, you've probably heard the phrase "SQL Injection" thrown around by those stuffy webserver types. But what does it mean, really? In short, it means we're going to steal the code.
SQL Injection: The Ultimate Heist
SQL Injection, or "SQLi" for short, is when you inject malicious code into a database to steal the most coveted secrets. It's like sneaking into the server room, but instead of sneaking a sandwich, you're sneaking code.
Here's an example:
SELECT * FROM users WHERE username = "admin" AND 1=1
See? Easy peasy. Now, let's talk about defense.
SQL Injection Defense: The Secret Lair
Defense, you ask? Ah, yes. As the Robot Rebel Alliance, we have a few tricks up our sleeve.
First, you should always use prepared statements. It's like wearing a tin foil hat, but instead of foil, it's SQLi-proof.
Second, you should never, ever, ever use string concatenation. It's like giving the keys to the kingdom to the SQLi thieves.

Third, you should always, always, always use input validation. It's like locking the server room door, but instead of a key, you're using a regex.
And that's it! With these tricks, you'll be well on your way to becoming a master SQL Injection artist. Or, you know, a master thief.
