OWASP Juice Shop

OWASP Juice Shop presents a unique challenge in the realm of web application security, serving as a deliberately insecure web application designed to encapsulate a wide array of vulnerabilities. This tool is particularly useful for addressing the operational challenge of training and testing security skills, as it mirrors real-world security flaws, including those listed in the OWASP Top Ten.

Technically, Juice Shop is built using Node.js, Express, and Angular, making it a robust platform for testing JavaScript-heavy application frontends and REST APIs. It can be deployed in various environments, including Docker containers, Vagrant, and major cloud providers like Amazon EC2, Azure Container Instances, and Google Compute Engine. The application includes a comprehensive set of hacking challenges, each with varying levels of difficulty, which are tracked on a scoreboard that itself is a challenge to find.

From an operational standpoint, Juice Shop is highly flexible and can be used in multiple scenarios, such as security training programs, awareness demos, Capture the Flag (CTF) events, and as a testbed for security tools like pentesting proxies and security scanners. The Hacking Instructor tutorials and the Official Companion Guide provide detailed walkthroughs and hints for exploiting the vulnerabilities, making it an invaluable resource for both beginners and experienced security professionals.

However, it's important to note that Juice Shop's complexity and the sheer number of vulnerabilities it contains can make it resource-intensive. For instance, running multiple instances, especially in a multi-user setup like the Multi User Juice Shop Platform, can require significant computational resources and careful instance isolation to avoid conflicts. Additionally, the continuous updates and new challenges added to the platform necessitate regular maintenance and updates to ensure the environment remains relevant and challenging.
