Medibank has revealed that the cyber attack on its customers' data is much wider than originally thought in a "distressing development".
- Medibank admits that data from some of its main brand customers has been compromised
- Previously, the company had only confirmed data from budget brand ahm and its international student insurance had been taken
- The company has apologised for the "distressing development" that means many more customers will be potentially affected
The healthcare provider first reported "unusual activity" had been detected on its network on October 12.
Since then, it had said the data breach was confined to its budget insurance company sub-brand ahm, and data collected about international students studying in Australia who use Medibank under its OSHC service.
On Tuesday morning, Medibank confirmed that data from its main brand was also now believed to have been compromised.
"This is a distressing development and Medibank unreservedly apologises to our customers," the company said in a statement this morning.
Medibank said it had come to this conclusion after being sent customer data by criminals that included data from all three entities.
All Medibank and ahm customers have been urged to contact the company's cyber response hotlines by phone (for ahm customers 13 42 46 and for Medibank customers 13 23 31) or through an information page on the firm's website.
Medibank said its customers can also speak to experienced and qualified mental health professionals 24/7 over the phone for advice or support around mental health or wellbeing (1800 644 325).
The company still does not know how many customers are impacted.
