U.K. Says Russia's Intelligence Service Engaged in Cyberattack Campaign

Russia’s intelligence service has carried out a yearslong cyberattack campaign against high-profile politicians, civil servants, journalists and others, according to the British government, as part of what it called “unsuccessful attempts to interfere in U.K. political processes.” The announcement, part of a joint action with allies including the United States, which announced related indictments and sanctions, was intended to sound the alarm that Russia intends to sow chaos and doubt ahead of elections in the United States and Britain.
