SYDNEY Australian airline Qantas said on Oct. 12 that data from 5.7 million customers stolen in a major cyberattack this year had been shared online, part of a leak reportedly involving dozens of firms. Qantas said in July that hackers had targeted one of its customer contact centers, breaching a computer system used by a third party. They secured access to sensitive information such as customer names, email addresses, phone numbers and birthdays, the blue-chip Australian company said. Credit
