From the Politico:

Election integrity advocates released a report today cautioning against online voting as an overlooked threat to election infrastructure. It’s susceptible to cyberattacks at nearly every point in the journey from voter to county clerk’s office, they say, warning that malware can remain undetected on a voter’s computer, voter authentication can be stolen, emailed ballots can be manipulated without detection and servers hosting ballots can be penetrated — none of which can be effectively audited.

Voters cast at least 100,000 ballots online in 32 states in the 2016 general election, according to the report, titled “Email and Internet Voting: The Overlooked Threat to Election Security.” It’s a collaboration between the National Election Defense Coalition, the Association for Computing Machinery, R Street and Common Cause.
