概述
Notifications began May 20, 2026. Ransomware groups claimed the attacks but the company has not confirmed this, so the method is recorded as unknown. No total is given. The first-disclosure date is the earliest public document confirmed (California AG posting); no 2025 public disclosure was found in other state AG lists, HHS or company notices checked.
