Optus, Australia's second largest telecommunications company, announced on September 22 that identifying details of up to 9.8 million customers were stolen from their customer database.
The details, dating back to 2017, include names, birth dates, phone numbers, email addresses, and – for some customers – addresses and driver's licence or passport numbers.
According to Australian law, telecommunications providers are required to hold your data while you are their customer and for an additional two years, but may keep the data for longer for their own business purposes.
