Six Russian intelligence officers accused of launching some of the “world’s most destructive malware” — including an attack that took down the Ukraine power grid in December 2015 and the NotPetya global ransomware attack in 2017 — have been charged by the U.S. Justice Department.

Prosecutors said the group of hackers, who work for the Russian GRU and reside in Russia, are behind the “most disruptive and destructive series of computer attacks ever attributed to a single group.”
