The term is loosely defined, and others seem to be biting on the bait of insulting facebook here. There are different ways the election process can be "attacked". Voter fraud is individual voters/real people committing fraud by, say, voting multiple times. Voting system fraud would be someone hacking the machines or ballot stuffing. There is gerrymandering, which is its own type of attack on the system. What Facebook is probably referencing, and what the Russia/Trump investigation was largely about, was disinformation/misinformation campaigns intended to produce a particular result in an election. While government can play a role in protecting people from this by debunking objectively false data and "hitting back" at state-sponsored campaigns, it shouldn't be shocking that the larger social media platforms have the insight and capability to detect and rebut *isinformation on their sites.
