About This Site
This blog serves as my platform for sharing insights from my cybersecurity journey. Here you'll find detailed walkthroughs of HackTheBox machines, technical deep-dives into vulnerabilities like XXE attacks, and practical security knowledge gained from real-world experience.
The content focuses on hands-on security testing, penetration testing methodologies, and defensive security practices. Whether you're learning offensive security techniques or building robust defensive architectures, I aim to provide practical, actionable knowledge.
The site may have some funky issues as I'm still working out the issues with css styling and learning custom MDX components to make things repeatable.
Note
If you see some funky post titles, content or posts in general. I may or may not be split testing SEO things in prod. You may also come across draft posts or incomplete content.
