Somewhere on the Earth

Bio

I’m Vojtěch, better known as TheSysRat — a cybersecurity maniac in the best sense of the word. I work as a Product Security Engineer at Tricentis, spend my free time on CTFs, and publish detailed write-ups to help others learn. I’m a Linux-first technologist who loves building prototypes, automating workflows, and occasionally coding up tools to solve real problems. Hack The Box Top 150, TryHackMe Top 150, and multi-season Holo rank in Hack The Box Seasons.
