Vulnerable Online Web Applications to Practice Security Testing

In a previous post we had a variety of offline webapps for you to practice your skills, in this post we have a collection of online web applications written in various programming languages.

 

Google Gruyere

This webapp has several deliberate flaws to help you find security vulnerabilities,

Learn how hackers find security vulnerabilities
Learn how hackers exploit web applications
Learn how to stop them

Gruyere has many security bugs ranging from cross-site scripting and cross-site request forgery, to information disclosure, denial of service, and remote code execution. The goal of this webapp is to guide you through discovering some of these bugs and learning ways to fix them both in Gruyere and in general.
