Illinois: Election Systems & Software Exposes Backup of Chicago Voter Roll via AWS Bucket | Threatpost

Voter registration data belonging to the entirety of Chicago’s electoral roll—1.8 million records—was found a week ago in an Amazon Web Services bucket configured for public access. The data was a backup stored in AWS by Election Systems & Software (ES&S), a voting machine and election management systems vendor based in Omaha, Nebraska. Researchers from UpGuard made the discovery last Saturday and privately reported the leak to a government regulator who connected them to the Chicago FBI field office. The FBI then notified ES&S, which immediately pulled down the data from Amazon. Amazon buckets are configured to be private by default and require some kind of authentication to access what’s stored in them. For some reason, ES&S misconfigured its bucket to public months ago, opening the possibility that others had accessed the data before UpGuard.
