The private information of more than one million Australians may be at risk following a fresh data breach involving a health service. Telehealth provider Updoc confirmed contact information may have been accessed during Friday’s attack. The online health platform said its own systems were “not accessed” and health, financial and payment details were not touched. Updoc has been targeted in a data breach impacting customers. Close to one million customers, meanwhile, were caught up in a cyber attack involving Origin Energy on July 22.
