Origin Energy says it is investigating a security breach that “may have” affected customer data.
“Origin Energy Limited (Origin) is currently investigating a potential security incident which may involve unauthorised access to some customers’ data,” it said in a statement.
“We do not believe the impacted data includes customer credit card or bank details.
“We understand an incident like this may raise concerns and acknowledge the impact of this uncertainty on Origin customers.
“Our investigations into this incident are occurring as a matter of urgency, and Origin will provide further updates as appropriate.”
Delay in revealing theft of medical data labelled ‘unacceptable’
The company said it had notified the Australian Cyber Security Centre and Australian Federal Police.
The Australian news outlet reported a hacker had sent it a sample of 50 customer records containing names, addresses, emails, dates of birth, phone numbers and bill history.
The ABC cannot immediately verify these claims.
It is understood that following this, Origin Energy alerted authorities to a potential security breach.
Origin Energy is one of Australia’s leading energy retailers with more than 4.7 million customers.
Upon the announcement shares in the company quickly dropped by 2.5 per cent.
The security breach is the latest for major companies in Australia, with Optus and Medibank both suffering mass breaches in 2022.
Last week Partnered Health, which operates a network of GP clinics, was targeted in a cyber attack, with sensitive medical records and personal information stolen.
