Delaware County

Delaware County government, also known as Delaware County or the County of Delaware, is a local governmental entity headquartered in the United States of America. It provides a range of public services to the residents of Delaware County, Pennsylvania, including law enforcement, judicial administration, public health initiatives, and maintenance of county infrastructure such as roads and bridges. As a county-level authority, it operates under the framework of state law and is responsible for implementing policies that affect community safety, welfare, and civic functions. The organization’s structure includes various departments and offices that coordinate to deliver services ranging from emergency management to record keeping and tax collection. Its role positions it as a key administrative body within the Commonwealth of Pennsylvania, interfacing with both state agencies and municipal governments within its jurisdiction. The county’s operations are supported by public funding and are guided by the elected officials who oversee its various functions.

In November 2020, Delaware County experienced a significant cybersecurity incident when it fell victim to a ransomware attack attributed to the DoppelPaymer gang. The attackers encrypted portions of the county’s network and demanded a ransom payment of approximately five hundred thousand dollars, which was reportedly covered by the county’s insurance provider. While the ransomware disrupted many internal systems, leading to the temporary shutdown of affected computers and services, emergency operations and election bureaus continued to function because they were hosted on separate infrastructure. During the intrusion, the threat actors accessed databases containing police reports, payroll records, and purchasing information, though it remains unconfirmed whether any data was exfiltrated or leaked. Following the attack, the DoppelPaymer group advised the county to undertake remediation steps such as enforcing password changes and adjusting Windows domain configurations to mitigate the risk of credential‑harvesting tools like Mimikatz. The incident highlighted the group’s typical tactics, which often include the potential exfiltration of unencrypted files, although no definitive evidence of data theft was presented in this case. The event prompted the county to review its cybersecurity posture and consider additional defensive measures to protect its information assets.
