'Coordinated inauthentic behaviour' - Facebook takes down hundreds of accounts linked to Russia and Iran
The social network said it had removed the accounts for “coordinated inauthentic behaviour”
Facebook has identified and banned more accounts engaged in misleading political behaviour ahead of the US mid-term elections in November.
The social network said on Tuesday that it had removed 652 pages, groups, and accounts linked to Russia and, unexpectedly, Iran, for “coordinated inauthentic behaviour” that included the sharing of political material.
Shortly after Facebook’s announcement, Twitter revealed that it had also suspended 284 accounts for “coordinated manipulation”, many of them apparently originating from Iran.
Facebook has significantly stepped up policing of its platform since last year, when it acknowledged that Russian agents successfully ran political influence operations on Facebook aimed at swaying the 2016 presidential election.
The social network said it had not concluded its review of the material and declined to say how or why the state-backed actors were behaving the way they did. But it said it had informed the US and UK governments as well as the US Treasury and State departments because of ongoing sanctions against Iran.
“There’s a lot we don’t know yet,” chief executive Mark Zuckerberg said on a hastily called conference call with reporters on Tuesday afternoon.
Facebook said the actions to remove the pages, groups and accounts on Tuesday morning were the result of four investigations — three involving Iran, and one involving Russia.
The first involved a group called Liberty Front Press that set up multiple accounts on Facebook and Instagram that were followed by 155,000 other accounts.
The group was linked to Iranian state media based on website registrations, IP addresses and administrator accounts, Facebook said. The first accounts were created in 2013 and posted political content about the Middle East, the UK, and the US, although the focus on the West increased starting last year, Facebook said.
FireEye, a cyber security firm that alerted Facebook to the Liberty Front Press group, called it an influence operation apparently aimed at promoting Iranian political interests “including anti-Saudi, anti-Israeli, and pro-Palestinian themes” and support for the US-Iran nuclear deal.
US president Donald Trump withdrew the US from that agreement earlier this year.
While that group did not appear to be attempting to influence the US mid-terms, FireEye said its analysis “does not preclude such attempts being made”. Several social media personas it found related to the group masqueraded as liberal US activists who supported Bernie Sanders.
The second group also had multiple accounts and 15,000 followers. The group was linked to Liberty Front Press and attempted to hack people’s accounts to spread malware. Facebook said it disrupted those attempts.
A third group also operated out of Iran had as many as 813,000 followers, and also shared political content about the Middle East, the UK and US.
In all, the Iranian-linked groups spent some $12,000 in advertising and hosted 28 different events.
A fourth group that attempted to influence politics in Syria and the Ukraine was connected to sources that Facebook said the US had linked to Russian military intelligence.
“We’re working closely with US law enforcement on this investigation,” Facebook said in a blog post.
