This notice supplements the August 17, 2017 press releases issued by Election Systems & Software (“ES&S”) and the Chicago Board of Election Commissioners (“Board”) with respect to the recent data
security incident involving Chicago voter registration information (“Incident”).

ES&S takes the security of your personal information very seriously, and sincerely apologizes for any inconvenience this Incident may cause. This update contains information about what happened, resources we are making available to you, and steps you can take to protect your identity.

As previously reported, on August 12, 2017 an Internet cybersecurity researcher discovered back-up files stored on an Amazon Web Services (“AWS”) server containing personal information of registered voters in the City of Chicago. The Incident was promptly reported to state and local authorities the same day, and the data exposure was remedied within hours.

The back-up files stored on the AWS server were maintained by the Board’s electronic poll book vendor, ES&S. The personal information contained in the back-up files included voter names, addresses, and dates of birth, and many voters’ driver’s license and State ID numbers and the last four digits of Social Security numbers.

Upon discovery of the Incident, ES&S promptly took the AWS server off-line, secured the back-up files, and commenced a forensics investigation. ES&S also hired two specialized third-party vendors to conduct searches to determine whether any personal information stored on the back-up files was available on the Dark Web. The results of ES&S’ investigations have not uncovered any evidence that any voter’s personal information stored on the AWS server was misused.

In addition, the back-up files ES&S stored on the AWS server had no impact on any of the Board’s voter records and had no impact on the vote tabulations or results of any elections. No computer network systems or web sites directly managed by the Board were exposed at any time. The Board’s web sites do not contain any personally identifiable information as described above.

Nonetheless, out of an abundance of caution, ES&S has arranged to have Kroll provide potentially affected voters with Fraud Consultation and Identity Theft Restoration at no cost to voters for one year. Kroll is a global leader in risk mitigation and response, and their team has extensive experience helping people who have sustained an unintentional exposure of confidential data.
