The U.S. government plans to launch a program in roughly one month that narrowly focuses on protecting voter registration databases and systems ahead of the 2020 presidential election.

These systems, which are widely used to validate the eligibility of voters before they cast ballots, were compromised in 2016 by Russian hackers seeking to collect information. Intelligence officials are concerned that foreign hackers in 2020 not only will target the databases but attempt to manipulate, disrupt or destroy the data, according to current and former U.S. officials.

“We assess these systems as high risk,” said a senior U.S. official, because they are one of the few pieces of election technology regularly connected to the Internet.
