The Australian Communications and Media Authority is taking legal action against Optus for a data breach in September 2022.

The breach compromised personal information of 10 million customers and resulted in a $1.5 million ransom demand from hackers.

The incident has sparked calls for stricter privacy regulations in Australia.

Optus is accused of failing to safeguard customer data, leading to the breach.

Former CEO Kelly Bayer Rosmarin resigned in the aftermath of the breach.

Parent company Singtel reported a significant profit decline due to the associated costs of the breach.

Optus is focused on rebuilding trust and enhancing services while addressing criticism for a previous network outage.
