Hello, I’m Marc-Oliver Munz, a 33-year-old IT Security professional in the Stuttgart region, Germany.

IT security isn’t just my job—it’s my passion. Whether by day or night, I actively engage in securing high-level companies, driven by a genuine commitment to cybersecurity.

My experiences extend globally, with participation in live hacking events connecting me with diverse cybersecurity professionals.

This blog is a window into my cybersecurity adventures, sharing insights from reaching top positions on platforms to discovering fascinating bugs.

I run this blog primarily for my own satisfaction, without a specific goal in mind.
