On December 29th of the previous year Polish energy infrastructure suffered a coordinated cyberattack. According to the recently published report by CERT Polska (English version available at: https://cert.pl/uploads/docs/CERT_Polska_Energy_Sector_Incident_Report_2025.pdf), the perpetuators had been preparing the security breach for months and had one single objective of causing as much damage as possible. The attackers’ communication patterns were found to be characteristic of a malicious activity cluster known as “Static Tundra,” “Berserk Bear,” “Ghost Blizzard,” and “Dragonfly.” As the report notes, “this is the first publicly described destructive activity attributed to this cluster.”
We find this #cyberFriday to be an appropriate moment to remind you of a paper from our 2023 special issue on the Russian-Ukrainian war, “Cyberwarfare against Critical Infrastructures: Russia and Iran in the Gray Zone” by Guillermo Lopez-Rodriguez, Irais Moreno-Lopez, and José-Carlos Hernández-Gutiérrez.
