About 30 percent of House candidates running for office this year have significant cybersecurity issues with their campaign websites, according to a new study.

Four independent researchers at a security conference over the weekend unveiled a report that indicates three out of every 10 House candidates are currently vulnerable to hacking and cyberattacks, according to Reuters.

The researchers, led by former National Institutes for Standards and Technology security expert Joshua Franklin, found that Democrats and Republicans are equally exposed.

The researchers presented their findings at the annual Def Con security conference in Las Vegas over the weekend.

"Russia continues to engage in cyber warfare against our democracy,” McCaskill said in a statement at the time. “I will continue to speak out and press to hold them accountable. While this attack was not successful, it is outrageous that they think they can get away with this."

Security experts at Def Con throughout the weekend addressed the holes in America's cybersecurity infrastructure, even hacking into voting machines to highlight the vulnerabilities, Reuters reported.

Franklin said his team of researchers is "trying to figure out a way to contact all the candidates" about the issues with their website security.

The White House earlier this month had top national security officials discuss the administration's efforts to confront Russian meddling in the midterm elections.

"The president has specifically directed us to make the matter of election meddling and securing our election process a top priority, and we have done that," Director of National Intelligence Dan Coats said during an appearance in the White House press briefing room.
