The attack targeted distributed energy. Industrial cybersecurity firm Dragos disclosed in a research report published Tuesday that a coordinated cyberattack late December on roughly 30 distributed energy sites across Poland's electric system marks a significant escalation in threats to modern power grids, as adversaries begin targeting. Russian Cyberattack Targets Poland's Power Grid in Winter Strike In late December, a coordinated cyberattack struck Poland's power grid, targeting at least 12 and likely closer to 30 distributed energy resource (DER) sites, including combined heat and power (CHP) facilities, wind farms, and solar. Poland is undergoing an ambitious energy transition, aligning with broader European goals to reduce greenhouse gas emissions and substantially increase the share of renewable energy sources (RES) in its national energy mix. A main aspect of this shift involves modernising and expanding its. Industrial cybersecurity firm Dragos, Inc. The incident, which Dragos. Solar energy in Poland is a rapidly growing sector of the country's renewable energy industry, driven by falling technology costs, government incentives, and increasing public interest in sustainable energy.
