Also see Facebook pilots new political campaign security tools — just 50 days before Election Day (TechCrunch)
"As we have seen in past elections, candidates and elected officials, as well as their staff, can be targeted by hackers and foreign adversaries across platforms, including Facebook. However, due to the short-term nature of campaigns, we do not always know who these campaign-affiliated users are, making it harder to help protect them.Expanding Security Tools to Protect Political Campaigns -- Facebook Newsroom
That is why, today, as part of our broader efforts to better secure Facebook, we are launching a pilot program to expand our existing protections for users associated with US political campaigns ahead of the 2018 midterm elections. Candidates for federal or statewide office, as well as staff members and representatives from federal and state political party committees, can add additional security protections to their Pages and accounts. Page admins can apply for the program at politics.fb.com/campaignsecurity and, once enrolled, they can add others from their campaign or committee. We’ll help officials adopt our strongest account security protections, like two-factor authentication, and monitor for potential hacking threats."
