Optus has suffered a massive data breach, compromising the personal information of up to 9 million customers.
About 2.8 million customers have had all their personal details taken in the cyber attack, including their passport and licence numbers, email and home addresses, dates of birth and telephone numbers.
About 7 million had their dates of birth, email addresses and phone numbers stolen.
The breach involves both current and former customers.
This is worrying.

If you said CIO, I'd potentially agree with you.
The CEO is the captain of the ship - it is redundant and unneccessary to say that the captain needs to be able to perform the functions and duties of every person on the ship. Sure, they should have an idea of what their role is, and perhaps some idea on how they perform it. But to say they need to be trained to perform those functions themselves is a bit much, in my opinion.
This is also why I said I'd potentially agree with you - as the CIO is the captain of the ship in the "Information" sense. They'd need to have more of an idea over their portfolio than the CEO would, but I don't (necessarily) agree that they should have to have done the training to perform all the functions that are performed within their portfolio.
