This room will introduce you to 3 elements of the OWASP Top 10 list (2025). In this room, you will learn about the elements relating to application behaviour and user input. We will cover these vulnerabilities briefly, how to prevent them, and finally, you will practice exploiting these vulnerabilities: A04: Cryptographic Failures A05: Injection A08: Software or Data Integrity Failures How to Prevent Cryptographic Failures Preventing cryptographic failures starts with choosing strong, modern algorithms and implementing them properly. Sensitive information such as passwords should be hashed using robust, slow hashing functions like bcrypt, scrypt, or Argon2. When encrypting data, avoid creating your own algorithms; instead, rely on trusted, industry-standard libraries. ...

Exam Duration and Difficulty I recently cleared the eJPT (eLearnSecurity Junior Penetration Tester) exam, and overall, it was a very solid learning experience. I completed the exam in about 35 hours, including sleep. While it wasn’t extremely hard to pass, I wouldn’t call it easy either. I’d place it somewhere between intermediate and hard, especially if you’re completely new to penetration testing. More About Penetration Testing Than Web Apps One thing that surprised me was that the exam is not very focused on web application penetration testing. There is some web-related work, but most of the exam feels more like real-world network and system-level penetration testing. You spend more time enumerating services, exploiting misconfigurations, moving through systems, and understanding how different parts of the network connect, which I personally enjoyed a lot. ...
