Facebook shut down two Russian disinformation networks operated by the nation's intelligence services and a third by people affiliated with a notorious troll farm that interfered in the 2016 U.S. presidential election, the company announced Thursday.
The networks focused their efforts in numerous nations in Europe and Asia, with relatively little reach among U.S. audiences, Facebook concluded. But the involvement of people and entities that previously had targeted American politics underscored the ongoing threat posed by Russia's disinformation machinery, which U.S. intelligence officials have said is attempting to interfere in November's presidential vote.
"Today's disclosures are further evidence that Russia continues aggressive interference operations and broader influence operations aimed at divisions within countries and among allies," said Graham Brookie, director of The Atlantic Council's Digital Forensic Research Lab, which tracks disinformation and studied two of the three networks removed by Facebook.
The tactics described by Facebook and outside researchers who studied the same networks suggest that Russia increasingly is using phony news sites and think tanks to lend credibility to its disinformation, in some cases involving unwitting freelance writers in the operations. This is a shift from the 2016 election and its immediate aftermath, when Russian operations were broader in their targeting, using fake accounts on Facebook, Twitter, YouTube and other social media platforms to spread messages to mass audiences based on their political or demographic characteristics.
The shift has been driven by the growing need by disinformation operatives to avoid detection and removal by social media companies and U.S. government agencies, said Nathaniel Gleicher, head of cybersecurity policy for Facebook. One of the networks was discovered by Facebook after a tip from the FBI, which has been monitoring Russian and other foreign actors online.
"They've been forced into using less effective techniques, but they are still trying," Gleicher said.
The three Russian networks involved nearly 350 accounts, pages and groups on Facebook and its photo-sharing subsidiary Instagram.
Overall the topics were wide-ranging and in line with Russian strategic themes, including the Syrian civil war, military conflict in Ukraine, Turkish politics, the coronavirus pandemic and the potential for civil unrest during the U.S. presidential election.
Rep. Adam Schiff, D-Calif., chairman of the House Intelligence Committee, issued a statement after Facebook's action, saying, "This is just the latest reminder that the Kremlin is undeterred -- and perhaps emboldened -- in launching new online influence campaigns. We must continue to publicly expose all elements of Russia's foreign influence and propaganda machine so we can harden our defenses and improve our collective vigilance as we cast ballots and prepare to tally votes in November."
