On Wednesday afternoon, both Facebook and Twitter came forward with announcements of coordinated election interference campaigns on their respective networks.

Facebook’s Head of Cybersecurity Policy Nathaniel Gleicher, wrote in a statement that the company removed a total of 652 Pages, groups, and accounts for such behavior. Their origin: Iran. Their targets: Facebook users in the Middle East, Latin America, UK, and U.S.

But it wasn’t just Facebook. Twitter also announced that it suspended 284 accounts for similar activity — also based in Iran.

Working with our industry peers today, we have suspended 284 accounts from Twitter for engaging in coordinated manipulation. Based on our existing analysis, it appears many of these accounts originated from Iran.

The campaign was discovered thanks in large part to a tip from cybersecurity firm FireEye, which published an analysis of its findings.
