FireEye posted this map making many of the connections between suspected pages in the network. It also identified a number of Twitter accounts linked to the campaign, and some Arabic-language sites that weren't included in its report. Tonight Twitter also announced it had suspended some 284 accounts "for engaging in coordinated manipulation" that it believes originated in Iran, but did not give many other details.

Another part of the Facebook investigation found fake accounts targeting Middle East users that dated back to 2011, and included a page with more than 800,000 followers. Altogether, pages in the campaign spent more than $12,000 on Facebook ads, and since Iran is under sanctions, Facebook is also working with the Treasury and State departments. According to FireEye's report, the pages it found did not appear to be specifically aimed at the 2018 midterm US elections, and extended well beyond just US audiences. What is apparent is that there's not just one group using social media to run influence campaigns that can reach nearly anywhere, and it's unlikely they'll stop making attempts.

Update (8/22): Russia has responded, with Kremlin spokesperson Dmitry Peskov saying the allegations are baseless. He also commented on Microsoft's recent takedowns of phishing sites it linked to Russian hackers: "They are all trying to outdo one another with their statements," he said.
