1,000 ahm policy records which include health claims and personal data.
Additional ahm, international student customer, and Medibank data.

Medibank also said in a statement that it was too early to ascertain the full extent of the data that has been stolen.

On 20 October 2022, the company shared that the criminal had contacted them and claimed that 200 GB of data had been stolen. The criminal had shared a sample of records of 100 policies. The data included some customer details and some claim data.

According to ASX announcement, the criminal also claimed to have stolen data related to credit card security. The company said that this was not yet verified in the investigation. Australian Federal Police (AFP) is handling the investigation of this cyber incident.

The health insurance provider was expected to declare a comprehensive customer support package. It would include:

24/7 well-being and mental health support
Support to those customers who are in a vulnerable position.
Availability of specialist identity protection advice with IDCARE for all consumers.

The company is expected to defer premium increases for ahm and Medibank customers until 16 January 2023.
