POLAND'S ENERGY GRID WAS TARGETED BY NEVER-BEFORE-SEEN WIPER MALWARE

Summary from the TLDR InfoSec newsletter

Poland's power grid faced a cyberattack in December that involved a new “DynoWiper” malware. Likely linked to Russia's Sandworm group, the attempt to disrupt electricity failed. The operation coincided with the 10th anniversary of Sandworm's landmark 2015 Ukraine blackout, and it fits a long pattern of Russian wiper use.
