Wiper malware targeted Poland energy grid, but failed to knock out electricity - Ars Technica

Security firm ESET reports that Poland's energy grid was targeted by wiper malware, likely from Russian state hackers, on the 10th anniversary of Russia's attack on Ukraine's grid. The attack, which occurred in December, aimed to disrupt communications between renewable installations and power distribution operators but failed. The malware, dubbed DynoWiper, is attributed to the Russian government hacker group Sandworm, known for similar destructive attacks. Despite the attack, there was no successful disruption of electricity delivery.
