How Many Customers Are Affected?

Expert Warnings About Identity Theft Risks

Cybersecurity experts, including Rumpa Dasgupta from La Trobe University, warn that the stolen data could be used for targeted phishing attacks and even physical crimes like burglary. Personalized information makes scams more convincing because hackers can impersonate legitimate businesses.

Steps to Protect Yourself After the Origin Energy Hack

  • Enable multi-factor authentication on all accounts, especially financial ones.
  • Monitor bank and credit card statements for unauthorized transactions.
  • Be cautious of unsolicited emails, calls, or texts claiming to be from Origin Energy.
  • Change your Origin account password immediately.
  • Consider placing a credit freeze or fraud alert with credit bureaus.

Origin Energy’s Response

CEO Frank Calabria apologized to customers and said the company is working with independent cyber experts and authorities. Origin has secured its systems to prevent further unauthorized access. A formal statement was filed with the ASX on Thursday.
