Australian energy giant Origin Energy has confirmed it is investigating a cybersecurity incident that may have exposed the personal data of millions of customers. The company, which holds 4.8 million customer accounts and supplies electricity, natural gas, LPG, and internet services across Australia, said it does not believe the breach included credit card or banking details. Origin has notified the Australian Cyber Security Centre, the Australian Federal Police, and the Office of the Australian Information Commissioner as investigations continue.
