Professional Background
Hi, I'm Viktor "vict0ni" Markopoulos. I am an offensive security engineer with a robust
track record in penetration testing, red teaming, and vulnerability research. Having graduated with a
bachelor's degree in computer science, I have since worked across three continents around the world in the private and the public sector.
I am deeply fascinated by problems and challenges, and I truly enjoy solving complex problems. My primary focus
lies in mastering the cyber operator's tradecraft across Web Applications, APIs, Active Directory, AI,
and malware.
