Sandworm's DynoWiper Targets Poland's Energy Sector in 2025 Cyberattack
In late December 2025, Poland's energy infrastructure was targeted by a cyberattack involving a data-wiping malware named DynoWiper. The attack aimed to disrupt operations at two combined heat and power plants and several renewable energy facilities. ESET researchers attributed the attack to the Russian state-sponsored group Sandworm, noting similarities to previous incidents involving the group. Fortunately, the malware was intercepted before causing any substantial damage, and no operational disruptions were reported.

The timing, coinciding with the tenth anniversary of Sandworm's first known assault on Ukraine’s power grid in 2015, highlights the group's continued focus on energy sector targets and disruptive operations.
