Poland says it repelled major cyberattack on power grid, blames Russia

Poland says it narrowly avoided a large-scale power outage after officials thwarted what they called the most serious cyberattack on the country’s energy infrastructure in years: attackers targeted communications between solar farms, wind turbines, and distribution operators across large areas in late December, an action ministers warned came “very close to a blackout.” Government leaders pointed to Russian sabotage as the likely cause, but declined to share technical details, formal attribution evidence, or specifics on mitigation steps.
