Russia Blamed for Cyberattack on Poland's Power Grid

Poland's power grid was targeted in December 2025 by a state-sponsored cyber operation attributed to Russia's FSB that attempted to deploy DynoWiper against multiple renewable energy facilities (wind and solar) to disrupt communications with distribution operators; the malware deployment failed to cause significant disruption, but authorities characterized the incident as destructive and unprecedented amid a surge of 270,000 cyberattacks in Poland during 2025, prompting calls to harden critical infrastructure.
