Black Hat Europe 2025 | Nation-Scale SecOps: How CERT PL Scans Poland

Author: Black Hat - Bewertung: 1x - Views:4

At CERT PL, a national CSIRT for Poland, we learned that the security of public entities is an area with numerous easily exploitable vulnerabilities and a significant need for free tools to improve the situation.

In this presentation, I will describe the approach we follow to enhance the security of public and private entities in Poland. I will introduce moje.cert.pl (meaning 'my CERT PL' in English), a system where administrators can join, scan their domains and networks for vulnerabilities, and receive notifications about user password breaches within their domains — all in one place and for free. I will also explain how we automatically scan tens of thousands of public entities in Poland (even ones that don't know about the CSIRT) and present Artemis, an open-source tool we developed to achieve this (and also to provide scanning in moje.cert.pl). Additionally, I will outline the philosophy behind building these tools.

I hope this talk will inspire you to run similar initiatives, whether you are part of a CSIRT, a hosting provider, or even a team of software engineers who want to make a positive impact.
