Hackers have breached Optus’ systems in one of the largest cyberattacks in Australian history, accessing names, dates of birth, phone numbers, email addresses, physical addresses and driver’s licence numbers of millions of the telecommunications giant’s customers.
Well-placed sources not authorised to speak publicly said that up to 9 million customers had been affected. Many had their contact details exposed to the hackers, who also pilfered even more sensitive details, such as passport and drivers’ licence numbers, for a smaller portion of Optus customers.

Depending on how much of the information the hacker or group have managed to extract, millions of Australians could be at risk of identity theft or fraud if the data is published or Optus could receive a ransom demand.
Optus chief executive Kelly Bayer Rosmarin declined to say who was behind the attack, how it was executed or how many accounts were compromised because investigations are ongoing, but described it as a “significant number” that included current and former customers.
