Free online courseSQL Injection Masterclass - Web Security Academy Labs

Course Description

Explore practical SQL injection skills with this free online masterclass focused on real-world web application security scenarios. Designed for learners in Cyber Security, it guides you through identifying, exploiting, and understanding SQLi weaknesses using hands-on Web Security Academy style labs.

You will progress from foundational concepts to increasingly advanced attack techniques, including data extraction from vulnerable queries, authentication bypass, UNION-based exploitation, and methods for discovering columns and pulling information from other tables. You will also learn how to enumerate database details such as type and version across common platforms, and how to list database contents in different environments.

The course dives deep into blind SQL injection approaches, covering conditional responses, error-based inference, time-delay techniques, and information retrieval when results are not directly visible. It also introduces advanced scenarios such as out-of-band interaction and data exfiltration, filter bypass strategies like XML encoding, and visible error-based SQLi workflows. If you want a lab-driven path to stronger web pentesting capability, this course provides a structured way to build confidence with SQL injection from start to advanced practice.
