A ransomware tracker listed the City of Columbia, South Carolina, as a Qilin victim and gave an attack date of October 29, 2026. The listing did not provide details beyond “N/A”; the city has not been confirmed as the source of the report in the available research.
No entity-level affected count, compromised data types, official breach notice, or regulator filing was found in the available sources. Whether Social Security numbers, medical information, or financial information were involved remains unknown. The available research also did not establish a consumer-notification date.
These details may change if the city or a regulator publishes further information. No later updates or notice dates are established by the sources available here.
