As Sen. Ron Wyden (D-Ore.) toured the Voting Village on Friday at Def Con, the world's hacker conference extraordinaire, a roomful of hackers applied their skills to voting equipment. By laying siege to electronic poll books and ballot printers, the friendly hackers aimed to expose weaknesses that could be exploited by less friendly hands looking to interfere in elections. Almost all of the machines in the room were still used in elections across the United States, despite having well-known vulnerabilities that have been more or less ignored by the companies that sell them. In the three years since its inception, Def Con's Voting Village ... has become a destination not only for hackers but also for lawmakers and members of the intelligence community trying to understand the flaws in the election system that allowed Russian hackers to intervene in the 2016 election and that could be exploited again in 2020. Congregants spoke often of the need for thorough auditing of election results, increased funding and improved transparency from vendors. The call for paper ballots was a common refrain. At the time of the 2018 midterm elections, Delaware, Georgia, Louisiana, New Jersey and South Carolina had no auditable paper trails. Election officials across the country as we speak are buying election systems that will be out of date the moment they open the box," Wyden said. "It's the election security equivalent of putting our military out there to go up against superpowers with a peashooter."
