Six men accused of carrying out some of the world's most destructive hacks—including the NotPetya disk wiper and power grid attacks that knocked out electricity for hundreds of thousands of Ukrainians—have been indicted in US federal court.

The indictment said that all six men are officers in a brazen hacker group best known as Sandworm, which works on behalf of Unit 74455 of the Russian Main Intelligence Directorate, abbreviated from Russian as GRU. The officers are behind the "most disruptive and destructive series of computer attacks ever attributed to a single group," prosecutors said. The alleged goal: to destabilize foreign nations, interfere with their internal politics, and cause monetary losses.
