In September 2017, the U.S. Department of Homeland Security (DHS) notified 21 states (including Illinois, Iowa, Minnesota, North Dakota, Ohio and Wisconsin in the Midwest) that Russian hackers had targeted their voting systems before the 2016 elections.
While most of the attempts were not successful, voter registration systems were breached in at least two states: Arizona and Illinois. (According to DHS, there was no evidence that any information had been altered in these two states.)
Fast-forward to today, with just months before the 2018 general elections that will determine partisan control of the U.S. Congress and several state legislatures, and elections security experts are recommending that immediate steps be taken to secure the country’s election infrastructure — for example, identifying the potential avenues for attacking election systems, replacing outdated voting machines, ensuring the security of registration systems, and conducting post-election audits.
Whether and when this occurs will depend in part on a mix of help from the federal government and new state-level policies and investments.
