DUBUQUE, Iowa (KCRG) – On Monday, the Dubuque County Auditor announced that the City of Dyersville’s email system had been compromised. Officials were clued in on the compromise after the City of Dyersville reached out to Dubuque County to check the status of an invoice they submitted regarding federal funds from the American Rescue Plan Act. The City of Dyersville had been granted approval for the funds to be used for projects, and Dubuque County determined that the invoice payment had already been made to the City of Dyersville for the claim. An internal review found that the invoice payment of $524,283.88 was made to the City of Dyersville but that the city never received it. Officials believe the payment was orchestrated by a third party. The incident is under investigation.
