As [we wrote in CyberDefence24] (https://cyberdefence24.pl/cyberbezpieczenstwo/rosjanie-zhakowali-oczyszczalnie-na-mazurach-efekt-propagandowy) in April this year, Russian hackers from the Cyber Army of Russia group **hacked water plants in the United States, a water mill in France, and a sewage treatment plant in Masurias**. Their effect was mainly propaganda; the only more serious effect was the leakage of respective 1000 liters of water at a plant in Muleshoe, Texas.
