Vojtěch Hron
Security researcher / Red teamer
I am a cybersecurity student. I hunt for vulnerabilities in software, dig into red team techniques, write my own exploits and pull malware apart. Alongside that I solve Hack The Box machines, play CTFs, build my own tools and write about the certifications I take. Everything here is my own work.
