Course Description

When I first successfully hacked a system years ago, I had to step away from my computer. It blew my mind... what was this power I had in my hands? That moment changed everything for me. Now, after creating tools that hundreds of thousands of ethical hackers worldwide use daily, I'm ready to share exactly how you can master the same techniques.

No, you won't learn this from books. You'll learn through hands-on practice - the most effective way to master these skills.


What You'll Actually Master

With 27+ hours of comprehensive hands-on content. From foundational techniques to advanced methods, you'll gain skills that translate directly to professional penetration testing, security consulting, or protecting your own systems.

Master 40+ professional tools, including Metasploit, Nmap, Burp Suite, SQLmap, Wireshark, Aircrack-ng, John the Ripper, Hydra, Maltego, SpiderFoot, and many more.

100+ real scenarios where you'll actually break into systems, networks, and applications in safe, controlled environments.


Real Skills, Real Results

I don't believe in watering things down. Yes, we start from zero - no Linux, programming, or hacking knowledge required. You'll be working with practical techniques used in professional penetration testing.

Here's what you'll master:

  • Build your complete ethical hacking lab from scratch (Kali Linux + Parrot OS Security)

  • Network penetration testing that reveals how vulnerable most systems really are

  • WiFi hacking techniques that crack WEP/WPA/WPA2/WPA3 encryption

  • Web application exploitation using advanced SQL injection and XSS attacks

  • Social engineering methods that bypass even the best technical defenses

  • Advanced OSINT gathering using Maltego, SpiderFoot, theHarvester, Shodan-eye, Amass, and other professional reconnaissance tools

  • Anonymity techniques that keep you invisible during testing

  • Steganography for hiding data in plain sight

  • Linux command mastery for serious penetration testers


My Track Record

  • Downloaded and used by hundreds of thousands of security professionals worldwide

  • Developed and maintained over multiple years of active use

  • Built based on real-world penetration testing experience

I didn't learn "how to do it" from books. I learn by doing. That means you never stop learning, never stop adapting. That's what builds true expertise.


Think Like a Hacker

This course isn't just about learning tools. It's about developing the hacker mindset - the curiosity that asks "what happens if I change this?" and the persistence that keeps digging when others give up.

You'll learn to think differently about everything you see. Every system has weaknesses. Your job is to find them first.


Your Complete Learning Path

Phase 1: Foundation Building

  • Ethical hacking fundamentals and legal boundaries

  • Linux mastery for penetration testers

  • Networking concepts that hackers exploit

  • Setting up your professional testing environment

Phase 2: Information Gathering & Reconnaissance

  • Advanced OSINT techniques

  • Network enumeration and fingerprinting

  • Social media intelligence gathering

  • Information discovery and research methods

Phase 3: Network Penetration Testing

  • WiFi security testing and encryption cracking

  • Man-in-the-middle attacks and traffic interception

  • Network vulnerability scanning and exploitation

  • Wireless access point security assessment

Phase 4: Web Application Security

  • SQL injection from basic to advanced

  • Cross-site scripting (XSS) discovery and exploitation

  • File inclusion vulnerabilities and bypasses

  • Web application reconnaissance and mapping

Phase 5: Advanced Techniques

  • Client-side attack vectors and social engineering

  • Malware analysis and detection evasion

  • Privilege escalation on compromised systems


Why This Works

No boring theory dumps. Every concept comes with immediate hands-on practice.

Real-world context. I explain why each technique matters and when you'd use it.

Continuous updates. New techniques are added regularly to keep content current.


The Bottom Line

Cybersecurity skills are in massive demand. Organizations, governments, and individuals are all seeking people who understand both offense and defense. This course gives you both.

The only question is: are you ready to think like a hacker?

Hacking is not a hobby - it's a way of life.

Instructor Details

Jolanda de Koff

When I started hacking, a long, long time ago, it was more about figuring everything out myself. I remember very well the first time I hacked something.... I had to step away from my computer. It blows my mind... Wow… what was this thing I had in my hands? Wow, what can you do with it? It feels like a weapon... It is! This made my interest even greater.

No, I didn't learn "how to do it" from books, I learn by just doing. It means that you never finished/stop learning.

Being a woman who hacks, and having the skills, is/was when I started not so usually. Still, it's a man's world. I had to be better than them. Sort of.. I had to prove myself. And not everyone liked it, for sure I can tell you that.. But it's getting better.

You have to stay ahead of everyone. That's what makes it also so much fun at the same time. But there is much, much more to it.

You have to learn to program. If you can't read code, you can't truly hack. Many so-called "hackers" forget this and remain script kiddies. Making your own tools for hacking is much more fun. Just learn some lines of code.

Linux is the main thing you should focus on. With Linux, you have the power, you own. Once you master Linux, you'll understand why ethical hackers live in the terminal.

My tools are used by hundreds of thousands of ethical hackers worldwide. Projects like shodan-eye, google_dork_list, and ghost_eye are actively used by the security community.

Overall very informative class. Lots of fun learning all the different techniques out there that hackers use to penetrate networks and what you can do about it.

By Udemy User on 4/1/2026

The accent of the instructor is difficult to understand and the pronunciation of many words are incorrect English. Following the material is difficult because of the cadence of the speaker. I will continue to try to get through the course but if it doesn’t get better, I may be asking for a refund in order to buy a different course.

By Benedict Bancure on 2/16/2026

This course is very interesting and informative. Everything is explained very well, clear, and in detail. As a developer and programmer, security vulnerability and data exploitation are a big deal that we must also consider aside from performance and user-friendliness. That is why I find the ethical hacking course like this one very interesting because we learn how to defend our systems we develop by learning the tools hackers use and how they work. Besides, I learn more about Linux operating system and its commands and tools. Thank you for teaching this course and well done.

By Ervin Myftaraj on 12/9/2025

I love the content and I love the paste of her speaking (Some other teachers either speak to slow or to fast.) I am really enjoying the course so far. I have been following Jolanda on LinkedIn for a while and I was very exited to hear that she came out with a Ethical Hacking course.

By Carmine Pastore on 11/3/2025

I feel like i didn't learn anything honestly, mostly explainations ant theory but very little practice ( i watched until section 6, more than 4 hours..) If you don't practice every single concept in every lesson, you won't remember anything. i have to make the hard work and trying to create my excercises, but then what's the point of paying a course? i could use chat gpt for explainations... and sections and lesson are not linked in any way to each others, so you learn something in lesson 1, then you learn something totally different in lesson 2, etc. then you change section and it's something totally different

By Vermont Ibanez Nuda on 10/31/2025

Enrolling in this course presents certain challenges for me, as I currently lack a background in Ethical Hacking. However, my keen interest in technology, particularly in the field of cybersecurity, motivates me to pursue this knowledge. I am grateful to have an instructor who possesses a clear understanding and delivers the lectures with precision.
