Optus Faces Penalties for Data Breach Incident in 2022

In a significant development, the Australian Information Commissioner (AIC) has filed civil penalty proceedings against Singtel Optus Pty Limited and Optus Systems Pty Limited, following the data breach that exposed the personal information of millions of current and former customers.

The data breach, which occurred between October 2019 and September 2022, affected 9.5 million Australians, with their names, dates of birth, home addresses, phone numbers, email addresses, government-related identifiers, and more being exposed.

The AIC alleges that Optus did not manage cybersecurity and information security risk adequately, failed to protect personal information from misuse, interference, loss, and unauthorized access, and did not take reasonable steps to protect personal information given its size, resources, the nature and volume of the personal information it held, and the risk of harm.

The investigation, initiated by the Office of the Australian Information Commissioner (OAIC), focuses on how Optus managed and secured personal information and whether the steps taken were reasonable. The breach also highlights the risks around using third-party providers.

The AIC may apply to the Federal Court for a civil penalty order, with one contravention for each of the 9.5 million individuals whose privacy it alleges Optus seriously interfered with. The Federal Court can impose a civil penalty of up to $2.22 million for each contravention, but the increased civil penalties of up to $50 million, which came into effect in December 2022, do not apply to this case.

The breach is in violation of the Privacy Act 1988, and the AIC's action aims to uphold the rights of the Australian community. The OAIC encourages organizations to implement procedures for clear ownership and responsibility over internet-facing domains, authorize requests for customers' personal information, layer security controls, implement robust security monitoring processes, appropriately resource privacy and cybersecurity, and regularly review practices and systems.

All organizations holding personal information need to ensure strong data governance and security practices to prevent such incidents from happening. The Optus data breach highlights risks associated with external-facing websites and domains, particularly when interacting with internal databases.

The plaintiff who filed the lawsuit against Optus is Monique Sutherland. The breach underscores the importance of robust data security measures and the need for companies to prioritize the protection of their customers' personal information.
