(Supplied)"I'm sorry this has happened. Customers trust Origin with their information, and I apologise for the impact this may cause," chief executive Frank Calabria said in a statement."One of our key priorities is taking action to secure our systems and ensure no further unauthorised access."The incident was first reported at 12:21pm yesterday by The Australian, which had been contacted by an alleged hacker who sent the outlet a sample of 50 customer records containing names, addresses, emails, dates of birth, phone numbers and bill history.It was only after The Australian sent that information to Origin that the company alerted authorities to a potential security breach. The company then notified the Australian Securities Exchange at 12:42pm.The statement this afternoon is the first comment made by the company regarding the incident since it confirmed its initial investigation.The ABC has spoken to a person claiming to be behind the hack, and has been provided with what the person claims is a sample of data taken from a bigger customer list and internal screenshots of Origin computer systems.The ABC has not been able to confirm with Origin that this data is legitimate.Analysis of the sample shows it includes the real contact information that had not been publicly released in other major security breaches.Origin is the country's largest energy retailer with more than 4.8 million customers across its electricity, gas, LPG and internet businesses.
