Illinois: Info on 1.8M Chicago voters was publicly accessible, now removed from cloud service: election officials | Chicago Tribune
A file containing the names, addresses, dates of birth and other information about Chicago’s 1.8 million registered voters was published online and publicly accessible for an unknown period of time, the Chicago Board of Election Commissioners said Thursday. The acknowledgment came days after a data security researcher alerted officials to the existence of the unsecured files. The researcher found the files while conducting a search of items uploaded to Amazon Web Services, a cloud system that allows users to rent storage space and share files with certain people or the general public. The files had been uploaded by Election Systems & Software, a contractor that helps maintain Chicago’s electronic poll books.
