Medibank faces trillions in fines following massive data breach

In an age where our personal information is as valuable as currency, the security of that data is paramount.

Unfortunately, this security was compromised in a significant breach involving Medibank, a giant health insurer.

The incident served as an alarm for more stringent data protection practices nationwide.


The breach, which occurred in October 2022, leaked sensitive personal information—names, birth dates, and Medicare numbers—online.

This breach puts over 9 million Australians at risk of identity theft and financial crime and can cause emotional distress.

The Office of the Australian Information Commissioner (OAIC) took a firm stance and filed civil penalty proceedings against Medibank.

‘We allege Medibank failed to take reasonable steps to protect personal information it held given its size, resources, the nature and volume of the sensitive and personal information it handled, and the risk of serious harm for an individual in the case of a breach,’ Acting Commissioner Elizabeth Tydd shared.

‘The release of personal information on the dark web exposed a large number of Australians to the likelihood of serious harm.’

The legal action taken by the AIC is a reminder of companies' responsibilities in safeguarding the personal data they manage.


Under the Australian Privacy Principles, entities like Medibank are required to protect the information they hold from unauthorised access—an ethical and legal mandate.

The potential fines facing Medibank are staggering, with the OAIC adding an infringement for each of the 9.7 million customers affected.

The maximum fine could exceed $21 trillion, dwarfing Medibank's reported revenue of $7.1 billion and annual profit of $560 million for the 2022 financial year.

While the Federal Court has yet to determine the outcome and applicable fines, this case is a cautionary tale for all organisations that handle personal data.

Foreign Minister Penny Wong's sanctions against Russian national Aleksandr Ermakov, who is allegedly involved in the breach, also underscore the international implications of cyber security.


As we await the court's decision, taking proactive steps to protect their personal information is crucial.

This includes:
  • Regularly changing passwords.
  • Monitoring financial accounts for unusual activity.
  • Being vigilant about sharing information online.
Those directly affected by the Medibank breach should contact the insurer for guidance on protective measures and stay informed about the company's support.

Additionally, individuals should consider placing restrictions on their credit files to prevent unauthorised credit applications.

The Medibank data breach is a sobering reminder of the vulnerabilities in our digital world.

It's a call to action for individuals and corporations to prioritise data security and take the necessary precautions to safeguard against such breaches.

It wasn't just Medibank - AHM (the so-called cheaper version) was also included with this. Medibank being the parent company. I was with AHM for a short time over 7 years ago and found out they (Medibank?) still had all my records. Why hasn't it been clarified that it is not just Medibank?

This occurred in October 2022. We learn about it on June 7th 2024? First I've heard about it. Goodness me, the speed of modern communications! However, I don't use even 2G let alone 3G on my mobile phone, which is now an archaeologist's dream. I will sell it to a museum or antiques dealer or collector for $10 000. That offer is not a scam; I will post it by express registered post on receipt of cash.
