The dicussion in this podcast details the landmark legal proceedings and outcome against Australian Clinical Labs (ACL) concerning a February 2022 data breach involving its acquired subsidiary, Medlab Pathology. The Australian Federal Court ordered ACL to pay $5.8 million in civil penalties for multiple breaches of the Privacy Act 1988 (Cth), marking the first such penalty under the Act. Specifically, ACL was found to have failed to take reasonable steps to protect personal information (affecting over 223,000 individuals), conduct a reasonable and expeditious assessment of the breach, and notify the regulator promptly. The court documents emphasize that ACL's failures were systemic, stemming from inadequate cybersecurity due diligence during the Medlab acquisition and deficiencies in their incident response, setting a new benchmark for corporate accountability regarding data protection and M&A cyber risk management in Australia.
