Yevheniya Nosyk
Cybersecurity Researcher @ KOR Labs | DNS WG Co-chair @ RIPE
About me
I am a cybersecurity researcher working on DNS, Internet measurements, and network security. I divide my time between academic research and outreach to the operational community, providing data and analysis that shed light on real-world deployments. I obtained a Ph.D in Computer Science from Université Grenoble Alpes in 2024.

I also occasionally write on RIPE Labs.
Selected Projects
Extended DNS Errors
I set up domains with many different types of misconfigurations to check how recursive resolvers handle those. Feel free to query them if you need to test something.
dnssoftver
I wrote a DNS fingerprinting tool to identify recursive resolver software running on remote machines. I am constantly looking for ideas to improve the software and add more test cases!
INFERMAL
I participated in the ICANN-funded project that aims to analyze the preferences of cyberattackers and propose measures to mitigate DNS abuse.
