Wiper Attack on Polish Power Grid Attributed to Sandworm
🔒 ESET has attributed a late-December 2025 wiper attack on Polish energy infrastructure to the Russia-aligned Sandworm APT and identified the malware as DynoWiper. Analysts reported strong overlaps with prior Sandworm wiper activity and assigned a medium-confidence attribution. Polish officials said critical systems were not disrupted and that two CHP plants and a renewable facility were targeted. The government is accelerating a National Cybersecurity System Act to strengthen IT/OT protections.
