For the third straight year, elite hackers from around the world who spent a long weekend hacking into voting equipment have released a report detailing vulnerabilities in machines still in use across the country. Each of the more than 100 machines the researchers looked at were vulnerable to at least some kind of attack, said Georgetown professor Matt Blaze, one of the Def Con Voting Village's organizers. As in previous years, the Voting Village collected versions of voting equipment used around the country, much of it ordered from eBay, and invited all of the more than 35,000 attendees of the Def Con hacker conference, which took place in Las Vegas in August, to see what kind of holes they could find. Some of machines were found to be vulnerable to remote attack and one electronic pollbook had a hidden ethernet cable to connect it to the internet. The issue is less that skilled hackers can break into election equipment, Blaze told CNN, and more that elections systems as a whole need to both minimize risk and double-check election results with paper ballots ... and risk-limiting audits. Following accusations that he'd been blocking election security legislation, Senate Majority Leader Mitch McConnell last week backed an amendment to give states an additional $250 million to distribute for election security. But experts have questioned whether that's enough money to get the US to an acceptable level of election security.
