Clinton County, Iowa, took parts of its network offline Wednesday, including internet connectivity, as officials investigated a disruption that could affect county services and may reflect a broader cybersecurity incident, according to WQAD and the Clinton Herald.
The outlets, citing county officials, reported that the disruption affected certain county systems and prompted a precautionary shutdown of parts of the network while IT and security teams, with outside assistance, worked to determine the nature and scope of the issue.
The county has not confirmed a cyberattack. Officials said there was no confirmed determination on the cause and no confirmed evidence of unauthorized access to or misuse of personal information.
Some county services may face temporary delays or limited availability while systems are restored safely and as quickly as possible, officials said. The county has not publicly identified which departments or public-facing services were affected.
The county did not respond Wednesday to an email from DysruptionHub seeking additional detail on the scope of the disruption, the services affected and whether investigators are examining a possible cybersecurity incident.
County governments have handled similar disruptions with varying levels of transparency. Catawba County, North Carolina, restored its website after a multiday outage but never confirmed it was the victim of a cyberattack, even after Qilin later claimed the county. Lucas County, Ohio, publicly described a “security incident” after taking systems offline, while Mitchell County, North Carolina, later said outages first described in operational terms were tied to ransomware.
Clinton County, north of Davenport along the Mississippi River, serves about 46,460 residents in 14 communities and oversees core local-government functions including courts, elections, sheriff’s operations, records and tax services.
The county said it would release more information as it became available.
