An app that some Denver voters used in 2019 has significant security issues, according to a new study from the Massachusetts Institute of Technology. The study that was released Thursday said hackers could potentially block or change a vote and steal a voter’s personal information from the app Voatz. The Denver Elections Division used Voatz in the May and June municipal elections for about 300 military and overseas voters. The Division did not report any security issues. “We were very happy with it,” said Director of Elections Jocelyn Bucaro. Burcaro said voter turnout increased significantly with Voatz. Traditionally, military members and others who are overseas and vote electronically would have to print a ballot, sign an affidavit, scan the documents and email them. Voatz allowed the voters to submit their ballots by just using a smartphone. Also, the division used a three-step process to ensure the app and votes were secure. “We are really grateful for the MIT researchers and releasing that report because we’ve been wanting more security review of the Voatz application and other vendors in this space,” Bucaro said.
