Remember: Penetration testing is a skill, and like any skill, it requires practice, patience, and the right resources. Let’s dive into how you can master the eJPTv certification, making what seems like a mountain merely a molehill to conquer.

Don’t forget to clap 👏 and follow for more updates on cybersecurity trends and insights!

Understanding the eJPTv Certification

The eJPTv certification is an entry-level credential designed to provide a fundamental understanding of penetration testing. It covers essential topics like information gathering, enumeration, scanning, vulnerability assessment, and various network-based attacks.

The certification exam consists of 35 questions, requiring a 70% passing score and must be completed within 48 hours​

My experience might not be remarkable in the grand scheme of things, but it’s a testament to what focused effort and the right resources can accomplish. With only two sessions of three hours each (more or less 6h in total without any stress) and access to essential study materials, I managed to pass the certification exam with a 77% score.

This achievement, while not astonishing, is quite impressive given the invested time and serves as a perfect example of quality over quantity when it comes to learning.

Recommended Prerequisites

Before embarking on the eJPTv certification journey, it’s advised to have a solid foundation in Linux, Windows, command line navigation, networking (TCP/IP), cybersecurity fundamentals, and basic programming/scripting skills. (I get them from university)

Experience with platforms like TryHackMe, CompTIA PenTest+, CEH, or a combination of similar certifications or educational paths can significantly benefit your preparation​. I did some of them but I am absolutely not a big cyber-challenger, I do that from time to time.

But for people not familiar with cybersecurity, it can be a plus !

Study Materials and Resources

• INE’s Penetration Tester Student Course: This is the primary resource for studying for the eJPT exam, offering extensive training and hands-on labs. However it is not free and absolutely not mandatory to pass the exam !
• TryHackMe and Rootme: Platforms that provide a plethora of Capture the Flag (CTF) challenges, aiding in the practical application of penetration testing skills.
• Hack the Box and Vulnhub: These platforms offer additional practice and exposure to real-world scenarios, enhancing your understanding and skills.
• YouTube and Google: Utilizing these resources for supplementary learning can help clarify complex concepts and provide different perspectives​

Tips for Success

Preparation Phase

1. Diligent Note-Taking: The foundation of success lies in taking detailed notes throughout your study. Organize your insights from videos and labs for quick reference during the exam. Tools like Notion or Obsidian can be instrumental.
2. Familiarize Native Kali Tools: Familiarize yourself with the tools available in a fresh Kali Linux install. The exam’s Attack Box lacks internet access, prohibiting additional tool installations. Key tools include Hydra for brute-forcing, Metasploit Framework for exploitation, and John The Ripper for hash cracking.
3. Focus on Weak Areas: Instead of revisiting the entire curriculum, prioritize areas that challenge you, such as pivoting and CMS attacks. Understand common CMS systems like WordPress and Drupal, focusing on enumeration, exploitation, and privilege escalation.
4. Create a Cheatsheet: A well-organized cheatsheet can be a lifesaver during the exam, providing quick access to commands, methodologies, and techniques for various attacks.
5. Organize Resources and Notes: Ensure your notes, cheatsheets, and lab write-ups are easily accessible. Use a structured template for documenting your exam findings to streamline the process.
6. Practice with Purpose: Engage in CTF challenges and lab exercises to solidify your understanding and application of penetration testing techniques, and it also allows manage your stress more easily !
7. Stay Curious: Explore beyond the course materials. The cybersecurity field is vast, and continuous learning is key to staying ahead​

Exam Phase

1. Take Your Time: Understand the material thoroughly; rushing through the training increases the likelihood of failure.
2. Brute-force: Usually, brute-forcing works ! (not like in real life) So don’t break your mind too much and brute-force !
3. Diligent Note-Taking: The foundation of success lies in taking detailed notes throughout your exam. You can use these notes for AI !
4. Leverage AI and Technology: Use AI tools to simulate test environments and automate tasks where possible. Reflecting on my experience, the eJPTv was more accessible than anticipated, even for someone relatively new to penetration testing. The key was leveraging available resources effectively and not underestimating the power of hands-on practice. AI and other technologies can play a significant role in simulating penetration testing environments, offering personalized learning experiences, and automating repetitive tasks for more focused study.
5. Understand the Letter of Engagement: Read it thoroughly to grasp the scope, resources available, and expectations. This document can offer insights into the network architecture and help plan your attack strategy.
6. Read All Questions Carefully: Analyzing all questions can reveal hints and relationships between them, aiding in efficient planning and execution.
7. Emphasize Enumeration: Never rush through enumeration. It’s the key to uncovering vulnerabilities and planning your attack strategy.
8. Persevere Through Challenges: When facing obstacles, revisit lab write-ups, notes, or course videos. Use Google for additional research, and remember to enumerate more if needed.
9. Approach as a Real-World Engagement: Treat the exam not as a CTF challenge but as a comprehensive penetration test. Focus on uncovering as many vulnerabilities as possible, not just obtaining flags.
10. Efficient Multi-Tasking: Optimize your approach by running comprehensive scans, automating brute force attacks, and cracking hashes in parallel with other tasks.
11. Take Regular Breaks: Breaks can help refresh your mind and improve problem-solving upon return.
12. Establish Relationships Between Questions: Compile questions related to a specific server together, aiding in targeted testing and comprehensive coverage.
13. Leverage Automation: Prepare bash scripts for repetitive tasks to save time and ensure thorough coverage.
14. Have Resources Ready: Before the exam, organize all necessary resources for quick access. This includes lab write-ups, notes, and essential websites.

​​Essential Tools and Techniques
