Voting machine companies and cybersecurity advocates are still miles apart on what it will take to secure 2020 against Russian hackers. During a nearly three-hour congressional hearing yesterday, security advocates sounded alarm bells about possible election hacks, warning machines in use today can be easily compromised. Companies, meanwhile, mostly defended the status quo. At one point, the chief executive of Hart InterCivic, one of three major companies that control more than 80 percent of the voting machine market, even defended selling paperless voting machines that can’t be audited and that top security experts and the Department of Homeland Security have warned are far too vulnerable in an era when elections are being targeted by sophisticated Russian hackers. “We actually believe our [machines] are secure,” said Hart CEO Julie Mathis, describing a number of internal defensive measures and security reviews they passed – primarily before 2016. The divisions highlighted how, despite three years of surging congressional attention to election security since Russia’s 2016 hacking efforts, there has been almost no government oversight of voting machine makers themselves. … Mathis’s comments were panned by security advocates. “It’s very simple. No matter how secure that device is, there’s no way to know whether the choice that’s recorded matches what the voter intended. It’s rightly called a black box,” Edward Perez, a former Hart executive who’s now global director of technology development at OSET Institute, a nonprofit election technology organization, said in an interview.
