We are a crew of offensive security operators, instructors, and community mentors who live and breathe practical hacking education.
I clawed my way out of addiction by turning the late-night exploits of The XSS Rat into disciplined reps that rebuilt my life. From sleeping in server rooms to streaming payload breakdowns for a global crew, I learned that obsession becomes unstoppable when it is shared. Rat Certs is where that energy lives now—hands-on labs, unfiltered war stories, and a community that proves hackers can rewrite their own narrative together.
