An investigation discovered a security breach in a software system that was used to hire and train Sedgwick County election workers.

County election commissioner Angela Caudillo reported the breach to county commissioners in March, and she told commissioners Wednesday that it happened in EZ Vote project management software.    She said it is used to hire and train election workers and plan for election supplies, and it is not connected to the voting systems, equipment or the voter registration database.

Caudillo said the investigation determined that an unauthorized person accessed certain files in an online storage system.   She said there were files that contained some personal information for election workers, including social security numbers and driver’s license numbers.    A notification letter is being sent to affected workers with an offer for credit monitoring and identity theft protection.     Caudillo said she is asking EZ Vote to include workers who had a partial social security number that was exposed.

Caudillo told commissioners that all files on election workers have been moved to a secure location, and her office is working to remove those files permanently.
