Position and history at ESET: Joined ESET in 2014 as Malware Analyst before becoming a Malware Researcher, nowadays mainly participating on threat research.

Highlights of your career: Having my paper accepted to the Virus Bulletin 2017 conference.

What malware do you hate the most? The one that brings no innovation and simply copies ideas and techniques from others while still causing a lot of damage.

Favorite activities: Computer games, traveling, reading and programming.

Golden rule for cyberspace? No matter what you do online, you are never 100% safe.

When did you get your first computer and what kind was it? Back in 1997 as a gift for Christmas. I was 6 years old at the time so I don’t remember its specs anymore, but was powerful enough to keep me occupied.

Favorite computer game / activity: Competitive games like League of Legends and RPGs
