Amazon's One Medical confirms a legacy-storage breach; ShinyHunters' 8.8TB claim is unverified and its deadline expires today

One Medical (Amazon) confirmed on 2026-06-13 that an unauthorised party accessed a legacy third-party file-storage system retaining archived records for One Medical Seniors (formerly Iora Health), during a 2026-06-08 to 2026-06-11 window, affecting demographic and clinical records for patients at nine clinics (BankInfoSecurity, 2026-06-19). One Medical states the breach is confined to that legacy system. Separately, ShinyHunters claims theft of 8.8 TB and set a 2026-06-22 negotiation deadline — today — but the company has not confirmed ShinyHunters' involvement or the data volume, and no sample has been released to validate the claim.
