JuicedShop Security Lab Series: Cryptographic Failures
Solution overview
Type: Red Team
Who Should Play: Security analysts, penetration testers, application security engineers, and technical leaders want to deepen their understanding of web application vulnerabilities through hands-on offensive techniques.
Objective:
In this mini game, you'll explore how weak or improperly implemented cryptographic protections can expose sensitive data to attackers. From outdated hashing algorithms to insecure token generation, even seemingly encrypted information can be cracked, manipulated, or misused when best practices aren't followed.
You'll examine how this Juice Shop application handles sensitive operations like password storage, token validation, and data transmission. By digging into the site's cryptographic design, you'll uncover flaws that allow access to protected resources and user data, all without breaking the encryption itself.
Why it matters: Cryptographic failures don't always require advanced math to exploit, often, they stem from misconfigured libraries, improper key management, or insecure defaults. Learning to identify and exploit these flaws helps highlight the importance of secure, by design implementations.
About the JuicedShop Mini Game Series:
Challenge yourself in a dynamic, hands-on mini game series based on OWASP Juice Shop, a purposefully vulnerable web application replicating real-world security flaws in a safe, sandboxed environment. This interactive experience includes ten unique mini games, each aligned with a specific vulnerability from the OWASP Top Ten - the most critical web application security risks recognized by the industry.
Whether you're exploring web app security for the first time or refining advanced ethical hacking skills, this series offers an engaging, gamified way to practice identifying, exploiting, and understanding common flaws found in modern websites.
