About this site

Hey! I'm René Espinosa and I'm specialized in offensive cybersecurity. I have been doing that for over a decade and counting. I have always found this domain pretty exciting since I saw for the first time Tron the animated series, user fighting the system administrator, loved that world from the very beginning. And from that moment I found technology fascinating and breaking technology even better.

Love the challenges and in cybersecurity there's plenty because even if you have a tested standard methodology there is always the unknown vector that will be waiting for you to uncover it. There is always a stone unturned.

You will find here my notes, driven by insomniac curiosity, a mind in overdrive, figuring out how things work until breaking them becomes the only way to truly understand them.
