The Computer Emergency Response Team of Ukraine (CERT-UA) has disrupted an attempt by Sandworm, a hacking group known to work for Russia’s military intelligence, to take down a Ukrainian energy provider. 

The Russia-backed hacking group attempted to disconnect the unnamed provider’s electrical substations using a new version of the infamous Industroyer malware, CERT-UA said in a security advisory on Tuesday. Industroyer was used by the Sandworm APT group to cut power in Ukraine in 2016, which left hundreds of thousands of customers without electricity two days before Christmas.
