ATLANTA (AP) — The nation’s leading cybersecurity agency says electronic voting machines from a leading vendor used in at least 16 states have software vulnerabilities. The U.S. Cybersecurity and Infrastructure Agency says the vulnerabilities can leave the machines susceptible to hacking if the flaws go unaddressed. The information is contained in an advisory that CISA sent to state election officials. It is based on testing by a prominent computer scientist and expert witness in a long-running lawsuit. CISA says there’s no evidence the flaws in the Dominion Voting Systems’ equipment have been exploited to alter election results. In a statement Tuesday, Dominion defended the machines as “accurate and secure.”
