Qantas Confirms Customer Data Released by Hackers Months After Cyber Breach

Australia’s national airline, Qantas Airways, has confirmed that customer data stolen during a July cyberattack has now been released online by cybercriminals. The airline said it was one of several companies targeted globally in the breach, which compromised the personal information of millions of passengers.

In the July incident, Qantas revealed that over one million customers had sensitive data — including phone numbers, dates of birth, and home addresses — accessed by hackers. An additional four million customers had their names and email addresses stolen, marking one of the largest data breaches in Australia’s recent history.

Qantas said the data was stolen through a third-party platform and has since been published by the hacker group known as Scattered Lapsus$ Hunters after the company missed a ransom deadline. “With the help of specialist cybersecurity experts, we are investigating what data was part of the release,” Qantas said in a statement.

The airline also confirmed that an injunction remains in place to prevent the use or further distribution of the stolen information. The July attack is among the most serious since cyber incidents targeting telecom firm Optus and health insurer Medibank in 2022, which led to tighter cybersecurity laws in Australia.
