This is a beginners' workshop on web application security. No prerequisites in web application security are required. A certain (web application) development background is beneficial.

First, we will be playing a virtual escape the room game with challenges on a web application to get into an attacker's mindset.
Then follows a quick introduction to the OWASP Top 10 vulnerabilities (2025 Release Candidate).
Finally use the gathered knowledge to attack a vulnerable web application (https://github.com/Phylu/vulnerable-click-game) and see how these attacks can easily be prevented.

Please bring your (fully charged) laptop to be able to participate.
