A data analytics firm employed by the US Republican National Committee “mistakenly” left sensitive personal details of more than 198 million US voters exposed on an unsecured Amazon S3 server. The exposed databases included personal data on more than 60% of the US population. The data included uniquely identified data on each voter, including their first and last name, date of birth, phone number, home and mailing address, party affiliation, voter registration data, and ethnicity, along with a flag should the person appear on the federal Do-Not-Call registry. The server was secured two days later after researcher Chris Vickery reported the blunder to federal regulators.
