Origin Energy confirmed that customer addresses, phone numbers, and partial bank account data were accessed in a hack. The company provides electricity, fossil gas, LPG, and internet services to 4.8 million customer accounts in Australia.

Accessed data may include customer names, dates of birth, phone numbers, Origin account information, the last four digits of a credit card, or the last three digits of a bank account.
