About This Site

This blog was initially setup for me to blog about my OSCP journey and to document my Hack The Box write ups. Now it's evolved into a bit of that and some, with random projects or stuff I'm currently working on trickling in to the content.

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.
