An undisclosed number of people may have been affected by the exfiltration of internal files, and anyone connected to the organization should review any notices issued and monitor their accounts for unusual activity.
Cityofsignalhill.org, the official site for the City of Signal Hill, California, was listed by the incransom ransomware group on November 28, 2025. The listing states that internal files were exfiltrated during a ransomware attack. The number of individuals affected remains unknown, and no further details on the scope or confirmation of the incident have been made public.
What happened
The only confirmed information is the appearance of cityofsignalhill.org on the incransom listing on the reported date. The entry claims that internal files were taken in a ransomware operation. No information has been released about when the intrusion occurred, how many files were involved, or whether any data was later published. The organization has not issued a public statement confirming or denying the claims.
Who is incransom?
Incransom is a ransomware group that has been publicly active in recent years. Like other groups of its kind, it typically gains access to target networks, deploys encryption on systems, and exfiltrates data before demanding payment. The group maintains a leak site where it lists organizations it claims to have compromised. Such listings serve as a pressure tactic and are not independently verified in every case. Prior public reporting has associated incransom with attacks on entities in multiple sectors, though specific tactics can vary between incidents.
Who is cityofsignalhill.org?
Cityofsignalhill.org belongs to the municipal government of Signal Hill, California, a small city that provides standard local services to residents. These include city administration, public events, job resources, water quality information, and community programs. The organization employs approximately 50 people and reports annual revenue of $7.1 million. Government websites of this type commonly store records related to residents, employees, vendors, and internal operations.
The information in question
The listing describes the exfiltration of internal files. No inventory of specific data categories has been released. Municipal organizations routinely hold personnel records, financial documents, resident service requests, and operational correspondence. Without an official disclosure, it is not possible to determine whether any of these categories were among the files referenced in the claim.
The real-world impact
Exposure of internal municipal files can create privacy risks for residents whose information appears in city records. It can also lead to operational disruption if systems were encrypted or taken offline. For a small government entity, recovery may involve extended administrative effort and costs. At present, the scale of any such effects remains unknown because the number of affected individuals and the precise contents of the files have not been disclosed.
What to do if you're exposed
Residents who have interacted with the City of Signal Hill should monitor their financial accounts and credit reports for unusual activity. Changing passwords for any city-related online portals is a basic precaution. Individuals can also request a copy of their records from the city to understand what information is held. A free exposure scan of an email address against known breach data can help identify whether personal details have appeared in other incidents.

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.
