The Grundy County Courthouse's servers and computers in Trenton had experienced a cybersecurity breach in January 2020.
The breach affected the systems of the county clerk, collector-treasurer, and assessor but the Information technology department was able to recover some information from a cloud backup.
It affected the general functioning of the residents who wanted to pay their taxes and were asked to bring in their bills until the systems were fully scanned and secured.
