Ballot Marking Devices are a new type of voting equipment in use across the United States. However, their security model relies on human intervention, and has not been thoroughly tested. Watch as a passionate puffer fish supporter has his vote stolen and fails to notice on the paper ballot, resulting in no votes for his preferred candidate being counted. This attack is robust to post-election audits too, as the paper ballots will reflect the tabulated results.

However, there are practical mitigations to this attack, which we detail in our recent paper "Can Voters Detect Malicious Manipulation of Ballot Marking Devices?", which you can read at https://mbernhard.com/BMD.
