SYDNEY (Reuters) - Australian authorities said on Friday they have commenced an operation to protect the personal information of 10,000 people whose data may have been shared online after a cyber attack on Optus, the country's second-largest telco.

The efforts come three days after an unidentified person posted online that they had released personal details of 10,000 Optus customers and would keep doing so daily until they received $1 million.
