City of New Castle Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The City of New Castle was listed by thegentlemen ransomware group on February 13, 2026, after internal files were exfiltrated in a ransomware attack. Individuals who may have interacted with city services should review any notices from the municipality and monitor their accounts for unusual activity.
Breaking down the breach
The available information is limited to the group’s listing. It reports that internal files were taken during a ransomware incident. No confirmation of the volume of data, the timeline of the intrusion, or whether any files were later published has been provided. The number of individuals potentially affected is listed as unknown.
The group behind it: thegentlemen
Thegentlemen is a ransomware operator that maintains a leak site where it lists organizations it claims to have targeted. Such groups commonly use double-extortion tactics, encrypting systems and copying files before demanding payment. They publicize victim names on their sites to increase pressure. The listing of the City of New Castle constitutes the group’s claim; independent verification of the underlying access or data handling has not been reported.
About City of New Castle
The City of New Castle is a municipal government in Delaware that provides services including permitting, utilities, and management of parks and community facilities. Like other local authorities, it processes records related to residents, property, and public administration. A compromise at this level can intersect with data that residents rely on for routine government interactions.
What data was at risk
The listing refers only to “internal files exfiltrated in ransomware attack.” No further inventory of file types or data categories has been released. Municipal organizations routinely hold records such as addresses, account information, and administrative correspondence, but the exact material involved in this case remains unconfirmed.
The real-world impact
Residents whose information appears in city files could face risks of misuse if the material circulates, including attempts at fraud or unauthorized account access. For the city, the incident adds operational strain from incident response and potential follow-on regulatory or legal obligations. The absence of Reported Details on scale limits precise assessment of downstream effects.
What to do if you're exposed
Monitor accounts for unusual activity and consider placing fraud alerts with credit bureaus. Change passwords for any city-related services and enable multi-factor authentication where available. Readers can run a free exposure scan of their email address to check whether their information appears in known breach data sets.

Publicly posted by thegentlemen — 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.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
