British intelligence has linked several cyberattacks, including meddling in the 2016 U.S. election, to the Russian agency that’s also been blamed for the Novichok poisoning this year. . . .
All the attacks were already linked to Russia but this is the first time Britain has linked them to the GRU [General Staff of the Armed Forces of the Russian Federation]. The United States had already linked the Russians to the 2016 hacking of the Democratic Party, where emails and chats were posted online.
