Kersey CO Listed by 8base Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target local governments and small municipalities across the United States, treating public-sector networks as reliable sources of sensitive records and operational disruption. In this climate, even modest towns can appear on criminal leak sites, leaving residents and staff uncertain about what may have been taken. One such case involves the Town of Kersey, Colorado, which was listed by the 8base ransomware group in mid-2023.

Public reporting on 25 July 2023 stated that Kersey CO had been named by 8base after an alleged ransomware attack in which internal files were claimed to have been exfiltrated. The number of people affected remains unknown, and further technical detail has not been released. The listing itself is a claim by the group; independent confirmation of the full scope has not been made public. For a small Colorado town, any exposure of internal records carries concrete consequences for residents, employees and local services.

What happened

According to the available record, the Town of Kersey, Colorado, was listed by the 8base ransomware group on or around 25 July 2023. The reported summary identifies the victim simply as the Town of Kersey and states that internal files were exfiltrated in a ransomware attack. No public figure has been given for the number of individuals affected. The precise date of initial intrusion, the entry vector, the duration of access, and whether systems were encrypted in addition to data theft have not been disclosed in the material at hand. What is known is limited to the group’s claim that it obtained and removed internal files and then posted the town on its leak site.

The group behind it: 8base

8base is a ransomware operation that became active in the public eye around 2022–2023. Like many contemporary groups, it has followed a double-extortion model: encrypting systems where possible while also stealing data and threatening to publish it if a ransom is not paid. The group maintains a leak site on which it names victims and, in some cases, releases sample files or larger archives. 8base has historically focused on mid-sized organisations and public-sector entities that may lack the resources of large enterprises, though its exact affiliate structure and tooling have evolved over time. In this instance, the group claims to have exfiltrated internal files from Kersey; that claim should be treated as an unverified assertion by the actors themselves rather than as independently confirmed fact. No additional statements attributed specifically to 8base about this victim beyond the listing and the description of internal-file theft appear in the provided record.

Who is Kersey CO?

Kersey is a small statutory town in Weld County, Colorado. Municipal governments of this size typically manage a range of local services—utilities, public works, planning and zoning, municipal court, and basic administrative functions—and therefore hold records on residents, employees, vendors and property. Such organisations commonly store names, addresses, contact details, utility-account information, employment and payroll data, and internal correspondence. A breach affecting a town government is consequential because the data often relates directly to people who live or work in the community and because disruption of municipal systems can affect day-to-day services. Public detail on Kersey’s specific IT environment or prior security posture is not part of the available facts.

What was likely exposed

The facts state only that internal files were exfiltrated in a ransomware attack. No inventory of file types, no count of records, and no confirmation of particular data categories have been released. Organisations of this kind ordinarily hold resident and employee personally identifiable information, financial and billing records, internal memoranda, contracts and operational documents. It is reasonable to expect that some mixture of those materials could have been among the taken files, yet the exact contents remain unconfirmed. Readers should not assume any specific data element was or was not present; the public record simply does not say.

The real-world impact

For individuals whose information may have been included, the practical risks include phishing or social-engineering attempts that reference local details, potential misuse of contact or account data, and longer-term exposure if records later circulate more widely. Employees could face risks tied to payroll or personnel files. For the town itself, consequences can include investigative and recovery costs, temporary disruption of administrative functions, and the need to notify affected parties and regulators once the scope is better understood. Because the number of people affected is unknown and the precise data types are undisclosed, the scale of harm cannot yet be quantified. The incident nonetheless illustrates how ransomware claims against small municipalities create lasting uncertainty for the communities they serve.

Were you affected?

If you live or work in Kersey or have had dealings with the town government, treat any unexpected messages that reference local accounts or personal details with caution. Monitor financial and utility statements for unusual activity, and consider placing fraud alerts with the major credit bureaus if you believe sensitive identifiers may have been involved. Change passwords on accounts that reused credentials tied to municipal services, and enable multi-factor authentication where available. You can also run a free exposure scan of your email address to check whether it has already appeared in known breach data sets. Official notifications, if any are issued by the town, remain the authoritative source for confirmed impact; until then, prudent monitoring is the most practical step.
