The data sets present information on 3,841 Twitter accounts affiliated with Russia's IRA, or Internet Research Agency, and on 770 accounts possibly originating in Iran, according to the company's blog post. Included are more than 10 million tweets and more than 2 million images, GIFs, videos and Periscope broadcasts dating back to 2009.

The majority of the tweets came from Russia's trolling operation, with 9 million tweets coming from the IRA, while the rest came from Iran's propaganda campaign. Ben Nimmo, a defense and international security analyst with the Atlantic Council's Digital Forensic Research Lab, received early access to the massive data dump.
