Hey guys! So, you're looking to dive into the world of cybersecurity, huh? That's awesome! If you're anything like me, you're probably aiming for that OSCP (Offensive Security Certified Professional) certification. It's a challenging but incredibly rewarding experience, and I wanted to share my journey, especially the parts that took me across some amazing places: Brazil, specifically Santa Catarina (SC), Argentina, and the broader cybersecurity landscape. I'll be real with you, getting the OSCP is not a walk in the park. It's intense, it's time-consuming, and at times, it feels like you're scaling Mount Everest with a rubber band. But trust me, the view from the top is worth it. Plus, the skills you acquire are invaluable for any aspiring penetration tester or security professional. Buckle up, because we're about to explore the ups and downs, the lessons learned, and the geographical twists and turns of my OSCP adventure.

Diving into the OSCP: The Initial Phase

Alright, let's start with the basics. The OSCP is more than just a certification; it's a test of your practical penetration testing skills. Unlike certifications that are heavily theory-based, the OSCP throws you headfirst into a real-world scenario: a lab environment where you have to compromise various machines. This hands-on approach is what makes it so valuable. You don't just memorize concepts; you apply them. Before I even thought about the exam, I spent months prepping. This involved a mix of online courses, virtual labs, and countless hours of reading and practicing. I utilized resources like OffSec's PWK (Penetration Testing with Kali Linux) course, which is essentially the official training material. This course will teach you the fundamentals: network scanning, enumeration, exploitation, and post-exploitation. It's comprehensive, but also pretty dense, so be prepared to dedicate a significant chunk of time to it. I highly recommend taking notes, and lots of them. The lab environment is a crucial part of the preparation. This is where you get to put your newly acquired skills to the test. It's a simulated network filled with vulnerable machines, and your goal is to compromise as many of them as possible. This is where you'll make mistakes, learn from them, and start to develop your methodology. It's also where you'll experience the frustration of banging your head against a wall for hours, only to realize you missed a small detail. The labs are the core of the learning experience, so treat them as such! Finally, you have to be persistent, you have to find and exploit the vulnerability. It's about finding the path that works best for you. Also, you must learn from the mistakes.

Brazil's Cyber Scene and OSCP Preparation

My journey took an interesting turn when I decided to tackle the OSCP while living in Brazil. More specifically, I was in Santa Catarina (SC), a beautiful state in the south of the country. This location offered its own set of challenges and opportunities. One of the biggest challenges was the time zone difference, especially when collaborating with peers or seeking online support. While Brazil has a growing tech scene, cybersecurity is still relatively nascent compared to North America or Europe. Finding local study groups or mentorship opportunities was trickier than I anticipated. The language barrier was an additional hurdle, as much of the official documentation and online resources are in English. This meant spending extra time translating and understanding the materials. On the flip side, the slower pace of life in SC provided a relatively relaxed environment for focused study. The beautiful beaches and outdoor activities were a welcome distraction from the intense studying, allowing me to recharge and avoid burnout. I found that balancing intense study sessions with breaks in nature was a crucial strategy for maintaining focus and motivation. Another key aspect was building a support network, even though it was primarily online. I joined online forums, cybersecurity communities, and Discord servers dedicated to OSCP preparation. These groups provided a valuable source of information, motivation, and a place to ask questions. I found that interacting with others who were going through the same process was essential for staying on track. I utilized a mix of paid and free resources. Besides the official OffSec course, I used websites, virtual labs like Hack The Box and TryHackMe, and books. I recommend to read the books that are the best for the OSCP.

Crossing Borders: Argentina's Cybersecurity Landscape and OSCP

Later on in my journey, I found myself in Argentina. The experience was quite different from Brazil. The cybersecurity landscape in Argentina is also evolving, though it has its own unique characteristics. Argentina has a strong tech community, and there are several cybersecurity companies and organizations. This provided a different perspective and exposure to the local cybersecurity practices. The biggest challenge in Argentina was the financial situation. The economy and currency fluctuation adds another layer of stress. Also, the availability of resources and infrastructure may vary, so be ready to adapt to different situations. The transition in Argentina was very unique. I tried to integrate into the cybersecurity community. Networking is vital. While the language barrier could be a factor, I was able to find many resources. I learned new ways of approaching problems. Being in a new environment, I was exposed to different perspectives. This added a valuable dimension to my learning. This exposure helped me to grow as a cybersecurity professional.

The OSCP Exam: The Final Hurdle

Okay, so you've done the labs, you've practiced, you've felt the pain and the joy of hacking, and you're ready for the exam. The OSCP exam is a 24-hour marathon of penetration testing, followed by a 24-hour window to write a detailed report. During the exam, you're given access to a set of machines that you need to compromise, just like in the lab environment. The goal is to obtain root or SYSTEM access on as many machines as possible, and you're rewarded for demonstrating your skills in a clear and organized manner. The exam tests your ability to think critically, apply your knowledge, and document your findings. Time management is crucial, as you have a limited amount of time to complete the exam. During the exam, I followed a structured approach. I started by scanning the network and enumerating all the machines. Then, I tried to identify potential vulnerabilities. Once I found a vulnerability, I'd try to exploit it. It's important to keep good notes during the exam. During my exam, the first thing I did was to create a checklist. The second thing that I did was to enumerate all the services and ports. Then, I started testing and exploiting. Be sure to document every step and take screenshots of the exploit. After the exam, you have 24 hours to write a penetration testing report. This report is a crucial part of the exam, as it demonstrates your ability to communicate your findings in a clear and concise manner. Your report must include all the steps you took to compromise the machines, along with evidence of your success. This part of the exam is just as important as the practical portion. Make sure to organize and format your report, using a professional tone. It is important to know that you can fail at the exam, but be prepared and learn from your mistakes. Learn how to write good reports.

Post-OSCP: Beyond the Certification

So, you passed! Congratulations! The OSCP is a fantastic achievement. After receiving the certification, I felt a sense of accomplishment. It opens doors to a whole new world of opportunities. The skills and knowledge you've gained will give you a competitive edge in the job market, and you'll be able to tackle more complex and challenging projects. The OSCP is just the beginning. The world of cybersecurity is constantly evolving. After the OSCP, you have to continue to learn and to grow. One thing is certain: your journey in cybersecurity is far from over. There are many other certifications and specializations you can pursue, like the OSWE, OSCE, or OSEP. The cybersecurity field is dynamic, so keep learning. Also, join communities. The cybersecurity community is full of people who are willing to share their knowledge and experience. Always remember that cybersecurity is about protecting people and data. I have worked in a variety of roles, from penetration tester to security consultant. It's been an incredible journey, and I'm excited to see where it takes me next. The OSCP gave me the confidence to pursue my passion. It is all about the attitude and the growth.
