County election websites in two battleground states are highly vulnerable to hacking by Russia or another adversary that might seek to disrupt the 2020 vote by misleading voters about polling locations or spreading other false information.
About 55 percent of county election websites in Wisconsin and about 45 percent in Michigan, both states that President Trump flipped from Democratic to Republican in 2016 lack a key and fairly standard security protection, according to data provided exclusively to me by the cybersecurity firm McAfee.
Without this protection, called HTTPS, it’s far easier for an adversary to hijack those sites to deliver false information, divert voters to phony sites that mimic the real ones or steal voters’ information, per McAfee. (You can often tell if a site has HTTPS protection if there’s a small lock icon to the left of a Web address.)
