Russian hackers attempted to launch a destructive cyberattack on Ukraine's electricity grid last week, Ukrainian officials and cybersecurity researchers said on Tuesday.
The group, dubbed "Sandworm" by security researchers and previously tied to destructive cyberattacks attributed to Russia, deployed destructive and data-wiping malware on computers controlling high voltage substations in Ukraine, the Computer Emergency Response Team of Ukraine (CERT-UA) said in a statement on its website.
