Miller County Government

Miller County Government is a local governmental entity serving residents of Miller County, Arkansas. It provides core administrative functions such as treasury management, record keeping through the clerk's office, and support for judicial proceedings via the judge's office. The county also oversees essential public utilities, including water services, which remained operational during cyber incidents. These services are delivered to the public through various county offices and facilities. During the October 2022 ransomware event, workstations in the treasurer, clerk, and judge's offices were compromised, prompting a shift to handwritten record-keeping while affected systems were wiped and reloaded. Although firewalls safeguarded core infrastructure, the exact duration required to restore normal operations remained unspecified.

The source notes that the ransomware attack in October 2022 affected 55 counties across Arkansas, indicating Miller County operates within a broader regional network of county governments. Additionally, the November 2020 incident involved systems shared with Bowie County and the cities of Texarkana in both Arkansas and Texas, suggesting collaborative or interoperable IT infrastructure across jurisdictional boundaries. Investigators discovered that the ransomware had been present on the network prior to its detection, indicating a prolonged undetected presence. Despite the compromise, officials confirmed that no personal information was accessed, and critical water services continued to function without interruption. While specific employee counts or budget figures are not provided, the involvement of multiple neighboring entities points to a notable footprint in the Ark-La-Tex region.

Miller County Government relies on external IT support from Apprentice Information Systems for the management of its computer systems, as indicated by the reference to that vendor in the 2022 attack description. The county's ability to maintain critical water services despite ransomware disruption highlights a degree of segmentation or resilience in its operational technology environments. Furthermore, the repeated targeting by ransomware underscores the county's exposure to cyber threats common among local government agencies that manage sensitive records and public utilities.

Miller County Government is a municipal corporation under the laws of the State of Arkansas, with its headquarters located in the United States of America. No information is provided about parent or subsidiary relationships, indicating it operates as an independent county entity. Its governance structure follows the typical county model with elected officials overseeing departments such as treasurer, clerk, and judicial offices.
