Delaware County Listed by doppelpaymer Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Delaware County Listed by doppelpaymer Ransomware Group (reported November 28, 2020) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
On November 28, 2020, Delaware County appeared on a leak site operated by the doppelpaymer ransomware group. The listing indicated that internal files had been taken during a ransomware incident, though the number of people affected and the precise volume of data remain undisclosed in public reporting.
Such listings have become a recurring feature of the threat landscape, where operators combine encryption of systems with the threat of data release. When a local government entity is named, the incident draws attention because county records often contain information that affects residents directly and because public-sector networks frequently support essential services.
Inside the incident
Public information is limited to the leak-site listing itself. The group asserted that internal data had been exfiltrated, but no confirmed count of records, list of file categories, or timeline of the intrusion has been released by Delaware County or investigators. It is not publicly known whether the data were later published or whether any ransom was paid.
Inside doppelpaymer
Doppelpaymer is a ransomware operation documented since at least 2019. The group has typically used targeted intrusions, often beginning with remote-desktop or phishing vectors, followed by deployment of custom encryption malware. A consistent element of its activity is the maintenance of a leak site where it lists victims and, in some cases, posts samples of stolen material. The Delaware County entry follows this established pattern of claiming data theft after an encryption event.
About Delaware County
Delaware County is a local government jurisdiction responsible for public records, courts, property assessments, health services, and law-enforcement support. These functions require the storage and processing of personal identifiers, financial documents, and operational files. A compromise at this level can therefore touch data that residents submit for routine government interactions.
What data was at risk
The only detail released is that internal files were claimed to have been taken. No inventory of specific data types—such as names, addresses, Social Security numbers, tax records, or medical information—has been confirmed. Organizations of this type routinely hold such categories of information, yet the exact contents of the exfiltrated material remain unverified beyond the general description of “internal files.”
The real-world impact
Residents whose information resides in county systems face the possibility that personal details could be used for identity-related fraud or targeted scams if the files are later distributed. For the county itself, the incident adds operational costs for investigation, system restoration, and potential notification requirements, even when the full scope of exposure is still unclear.
If your data was in this claimed breach
Monitor financial accounts and credit reports for unusual activity. Place fraud alerts or credit freezes if you have interacted with Delaware County services. You can also run a free exposure scan of your email address against known breach data to determine whether your information has appeared in other incidents.

Publicly posted by doppelpaymer — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
