• Qantas suffered a cyberattack in early June 2025
• A thorough investigation has now placed the number of affected individuals at 5.7 million
• Passwords and payment data is safe, but crooks took names, addresses, and other PII

Qantas has confirmed sensitive information on 5.7 million customers was exfiltrated in the recent cyberattack it suffered.

Australia’s largest airline said it recently spotted an intrusion after a threat actor targeted a call center, and accessed a third-party customer servicing platform. Initially claiming that six million people were affected, Qantas has now came forward with more precise figures.

In a press release published on the company’s website, it said the attackers took four million customer names, email addresses, and Qantas Frequent Flyer details. For the remaining 1.7 million, they also stole postal addresses, dates of birth, phone numbers, gender, and meal preferences.
