All Medibank customers had their data accessed in the recent cyber attack, the health insurer has confirmed.

This includes up to 4 million customers across Medibank, ahm and international student customers.

In an investor update on Wednesday morning, Medibank said the investigation had now established that criminals had access to all Medibank, ahm and international student customers’ personal data and significant amounts of health-claims data.


“As previously advised, we have evidence that the criminal has removed some of our customers’ personal and health-claims data and it is now likely that the criminal has stolen further personal and health-claims data,” Medibank said in an ASX statement.

“Our priority is to continue working to understand the specific data that has been taken for each of our customers so that we can contact them directly to let them know.”

Support for customers

Medibank yesterday announced a customer-support package, including mental health and well-being support and free identity-monitoring services for customers who have had their primary ID compromised.

The health insurer will also reimburse fees for customers to reissue identity documents that have been fully compromised in this crime.

Medibank will defer premium increases for Medibank and ahm customers until January 16, 2023.

More to come.
