SIA Medical Centre (Vic) investigating unauthorised access after a Rhysida ransomware listing; says it is contacting people whose documents were published and has informed the OAIC and ACSC

Cyber Daily (18 August 2026) reports Victorian multi-clinic operator SIA Medical Centre is investigating unauthorised access after the Rhysida ransomware group listed it on 12 August.

An SIA spokesperson said the organisation engaged cyber experts to contain the incident and assess personal information accessed; it has become aware an unknown third party named it online and published a small number of documents, is notifying those individuals, and has informed the Office of the Australian Information Commissioner and the Australian Cyber Security Centre. Distinct from other Rhysida cards on this desk (e.g. Berlin state-network).

Correction (23 Oct 2026): removed Rhysida's own claims about record counts, data types, price and deadline; SIA has said only that a small number of documents were published.
