DynoWiper Used in Attempted Sandworm Attack on Poland
⚠️ A new wiper malware named DynoWiper was used in an attempted disruptive attack on Poland's power sector on December 29–30, 2025, according to a report by ESET. The activity is attributed to the Russia-linked group Sandworm based on overlaps with prior wiper campaigns. Targeted systems included two CHP plants and a renewables management system, but officials report no evidence of successful disruption. Poland is accelerating safeguards and drafting stricter cybersecurity legislation for IT and OT risk management and incident response.
