Module 5: SQL Injection Mastery How 10 Million Attacks Happen (and How to Stop Them)
In early 2024 alone, over 10 million SQL injection attempts were blocked. Despite being decades old, SQLi remains a "devastating" threat to modern databases, responsible for some of the largest data breaches in history.
Video Summary: In this deep dive, we break down the anatomy of a SQL Injection (SQLi) attack. You’ll learn how attackers use special characters like the single quote (') and double dash (--) to trick Relational Database Management Systems (RDBMS) into leaking sensitive info. We move beyond the basics to explore Union-Based, Blind (Boolean/Time-based), and Error-Based injection techniques.
What You Will Learn:
The Basics of SQL & RDBMS: Understanding tables, schemas, and how applications talk to databases.
Logic Manipulation: How logical operators like OR and AND are used to bypass authentication (e.g., ' OR '1'='1).
Case Studies: A look at the Yahoo (3 billion accounts) and Target (40 million credit cards) breaches.
Advanced Attacks: How SQLi can be chained with OS Command Execution, as seen in the Accellion attack.
Primary Defenses: Implementing the "Gold Standard"—Prepared Statements (Parameterized Queries).
Defense-in-Depth: Using Web Application Firewalls (WAF), Input Validation (Allow-lists), and the Principle of Least Privilege.
