The city of Chicago on Friday said that employee emails were compromised in a Jones Day data breach involving Accellion's FTA file sharing service.

On Friday, the city of Chicago revealed that some employee emails that were given to Jones Day "As part of an independent inquiry being conducted by the firm" were compromised in the incident.

The data breach only affected the Accellion FTA service and involved "Emails sent or received from four former City employees over a two-year time period," the city said.

The Chicago Department of Assets, Information and Services, the city also reveals, has already notified the FBI and the Illinois Attorney General's office on the leak and took the necessary action to ensure that the emails were removed from the file transfer service.

"While the city is not aware of any fraud that might have resulted from this event, it has taken the matter very seriously and responded accordingly," the city says.

The city says it was able to determine the number of impacted people and that it has already taken steps to notify the individuals who might have had personal information included in the compromised email files, either directly or through a notice on its website and a state-wide media alert.
