The New York Times reports:

The Russian influence campaign on social media in the 2016 election made an extraordinary effort to target African-Americans, used an array of tactics to try to suppress turnout among Democratic voters and unleashed a blizzard of posts on Instagram that rivaled or exceeded its Facebook operations, according to a report produced for the Senate Intelligence Committee.

The report adds new details to the portrait that has emerged over the last two years of the energy and imagination of the Russian effort to sway American opinion and divide the country, which the authors said continues to this day.

“Active and ongoing interference operations remain on several platforms,” says the report, produced by New Knowledge, a cybersecurity company based in Austin, Texas, along with researchers at Columbia University and Canfield Research LLC. One continuing Russian campaign, for instance, seeks to influence opinion on Syria by promoting Bashar al-Assad, the Syrian president and a Russian ally in the brutal conflict there.

The New Knowledge report, which was obtained by The New York Times in advance of its scheduled release on Monday, is one of two commissioned by the Senate committee on a bipartisan basis. They are based largely on data about the Russian operations provided to the Senate by Facebook, Twitter and the other companies whose platforms were used.

The second report was written by the Computational Propaganda Project at Oxford University along with Graphika, a company that specializes in analyzing social media. The Washington Post first reported on the Oxford report on Sunday.

The Russian influence campaign in 2016 was run by a St. Petersburg company called the Internet Research Agency, owned by a businessman, Yevgeny V. Prigozhin, who is a close ally of President Vladimir V. Putin of Russia. Mr. Prigozhin and a dozen of the company’s employees were indicted last February as part of the investigation of Russian interference by Robert S. Mueller III, the special counsel.

Both reports stress that the Internet Research Agency created social media accounts under fake names on virtually every available platform. A major goal was to support Donald Trump, first against his Republican rivals in the presidential race, then in the general election, and as president since his inauguration.

Creating accounts designed to pass as belonging to Americans, the Internet Research Agency spread its messages not only via Facebook, Instagram and Twitter, which have drawn the most attention, but also on YouTube, Reddit, Tumblr, Pinterest, Vine and Google+, among other platforms. Its attack on the United States used almost exclusively high-tech tools created by American companies. [Continue reading…]
