Cyber Intelligence firm GroupSense released a report detailing how a network of at least 9.5 million email addresses, which appear to come from high profile data breaches, was used both by Russia for its social media campaign and to send FCC comments both supporting and opposing net neutrality.
The report, titled SHARK20385: A look into automated weaponization of stolen credentials and the impact to Internet forum and social media discourse, is a well done deep dive into both open source data and the databases of GroupSense.
Key conclusions are that the same bad actors that were attempting to cause discord before during and after the U.S. Presidential Elections (the Russian Intelligence Services) were seeking to cause discord on public policy, including the FFC net neutrality issues.
Russia is clearly still interfering with Western institutions.
