SYCAMORE – A week after DeKalb County government endured a ransomware attack, county officials confirm email servers are back up and running.
DeKalb County Administrator Brian Gregory said Monday the county’s information technology staff was able to restore the servers as of Saturday morning.
“We had good backups, so we were able to use our backups to bring back up the servers,” Gregory said. “So we were fortunate.”
Gregory said the majority of the county’s servers are back up or in the process of being brought back up Monday afternoon. He said the county’s information technology staff continues to go “from department to department, computer to computer” and they “did a great job” in working around the clock to get the county servers operational again.
“It’s a testament to the work they do day in and day out with the back up to bring a network this size of ours back online with, all things considered, with little impact,” Gregory said.
DeKalb County Sheriff Andy Sullivan said Monday sheriff’s dispatchers are back at the sheriff’s office after they had to work out of the DeKalb Police Department last week. The DeKalb department shares the computer-aided dispatch and radio system with the sheriff’s office.
The sheriff’s office’s system was corrupted in the Oct. 11 ransomware attack, but the county was still able to dispatch and answer 911 emergency calls because of the shared systems, Sullivan said.
Sheriff’s officials also previously confirmed the county jail’s booking logs were kept manually.
“We have been back at the sheriff’s office since Thursday evening, doing dispatch and normal jail bookings,” Sullivan said.
Gregory confirmed it still does not appear that any county files have been compromised, nor do any files or additional information appear to be missing.
DeKalb County government offices were closed a week ago because of the Columbus Day and Indigenous People’s Day holiday.
Government agencies have been subjected to ransomware attacks both in Illinois and nationally in recent months. Earlier this spring, Illinois Attorney General Kwame Raoul’s office announced the state agency had been subjected to a ransomware attack. The Chicago Tribune reported in July that the attorney general’s office spent more than $2.5 million handling the crisis.
Sullivan and Gregory confirmed an investigation regarding the attack continues with the sheriff’s office and county law enforcement officials are working with the FBI’s Chicago office. Both said Monday the source and cause of the attack are still unknown.
