Sensitive information about almost 10 million Australian Telecoms subscribers may have been compromised by a massive hack of the country’s second-largest provider, the firm revealed, Friday.
Optus Chief Executive Officer, Kelly Rosmarin, said a “sophisticated” actor was behind a cyber attack, which gained access to information of about 9.8 million users.
The data accessed included customers’ names, dates of birth, phone numbers and email addresses, as well as some driver’s licence and passport numbers.
No passwords or bank details were taken, according to the Singapore-owned firm.
It is not yet clear whether the attack came from a state-based or criminal organisation, but it said that said no ransom demand had been made.
