"Participants vetted dozens of voting machines at Defcon this year, including a prototype model built on secure, verified hardware through a Defense Advanced Research Projects Agency program. Today's report highlights detailed vulnerability findings related to six models of voting machines, most of which are currently in use. That includes the ES&S AutoMARK, used in 28 states in 2018, and Premier/Diebold AccuVote-OS, used in 26 states that same year. "As disturbing as this outcome is, we note that it is at this point an unsurprising result," the organizers write. "It is well known that current voting systems, like any hardware and software running on conventional general-purpose platforms can be compromised in practice. However, it is notable—and especially disappointing—that many of the specific vulnerabilities reported over a decade earlier ... are still present in these systems today... This confirms what we’ve been saying for years now—around the country, we’re still using antiquated equipment that should be replaced, both for security and reliability reasons," says Lawrence Norden, deputy director of the Brennan Center's Democracy Program at New York University School of Law."
