Utsunomiya Central Clinic

Utsunomiya Central Clinic, a cancer treatment center in Japan, suffered a cybersecurity breach due to a ransomware attack by the Qilin gang. Services were disrupted and data of nearly 300,000 individuals, including patients and staff, was exfiltrated. Compromised information included names, birthdates, medical details, and contact information. Although Social Security numbers and financial details were not affected, exposed health information such as radiology images and medical files was confirmed. Individuals affected are being cautioned about potential fraud.
