Philip Ewing reports Russian Election Trolling Becoming Subtler, Tougher To Detect:
Russia’s trolling specialists have evolved their disinformation and agitation techniques to become subtler and tougher to track, according to new research unveiled on Thursday.
A cache of Instagram posts captured by researchers showed that the Russians were “better at impersonating candidates” and that influence-mongers “have moved away from creating their own fake advocacy groups to mimicking and appropriating the names of actual American groups,” wrote Young Mie Kim, a University of Wisconsin professor who analyzed the material with her team.
Kim, who is also affiliated with the Brennan Center for Justice at New York University, discussed the analysis in a new report that also included images of some of the posts.
Kim and her team identified 32 Instagram accounts they said appeared to be linked to Russia’s now-infamous Internet Research Agency, of which 31 later were confirmed to be IRA-linked by an analysis commissioned by Facebook, which owns Instagram.

Russian influence operations are aimed at sowing chaos and amplifying division as much as bringing about a specific political result, national security officials say.
To that end, influence specialists posed as American grassroots or community activists and targeted populations with the intent to divide them or convince them not to vote, Kim wrote.
“The IRA is well-versed enough in the history and culture of our politics to exploit sharp political divisions already existing in our society,” Kim wrote. “American nationalism/patriotism, immigration, gun control and LGBT issues were the top five issues frequently discussed in the IRA’s campaigns.”
Josh Gerstine reports Feds: Mystery witness will implicate ‘Putin’s chef’ in election interference:
U.S. prosecutors say they have a witness who will directly implicate a Russian businessman known as “Putin’s chef” in schemes to carry out election interference overseas.
The mystery witness is prepared to testify at a criminal trial set to open in Washington next month in a case special counsel Robert Mueller brought accusing three Russian companies and 13 Russian individuals of meddling in the 2016 U.S. presidential election, a prosecutor declared at a recent court hearing.
The anticipated testimony will focus on the most prominent Russian national charged in the indictment, Yevgeny Prigozhin, a St. Petersburg restaurateur who enjoys close ties to Russian President Vladimir Putin and who has expanded his business empire to become a key contractor for the Russian military.
Prosecutors say Prigozhin ran the Internet Research Agency, a Russian firm that allegedly sponsored and coordinated online troll activity during the 2016 U.S. election.
