On February 16, 2026, Modoc Medical Center, a healthcare provider in Alturas, California, was reportedly affected by a ransomware attack claimed by the Worldleaks group. The incident was publicly claimed by Worldleaks on dark web leak sites, but no official notifications from the center or regulators have been reported.
The compromised data types are described as "sensitive medical data," and the ransomware group threatened to release a "full dump" of this information. However, the specific number of affected individuals has not been reported, and it remains unclear whether Social Security numbers or financial data were exposed.
Breach investigations and notification timelines can evolve after an initial report, and additional details are sometimes released later.
