Qantas Airways has confirmed that stolen customer data from a cyberattack in July has been published by cybercriminals. The Qantas Data Breach, which targeted a third-party platform used by the airline, exposed sensitive information for over a million passengers and additional details for millions more.
Scale of the Qantas Data Breach
In the initial incident, Qantas reported that more than one million customers had sensitive personal information accessed, including phone numbers, birth dates, and home addresses. Another four million customers had less detailed information taken, such as names and email addresses. The airline described the July breach as one of Australia’s largest cyberattacks in recent years, following earlier incidents affecting Optus and Medibank in 2022. Those breaches had previously prompted stricter cyber resilience regulations across the country.
The Qantas Data Breach was carried out via a third-party platform, underscoring the growing risks associated with external service providers handling sensitive data. Qantas has stated that it continues to investigate the full extent of the release with the assistance of cybersecurity experts.
Data Published by Hacker Collective
The group responsible for releasing the data is the hacker collective Scattered Lapsus$ Hunters. According to reports, the data publication followed the expiry of a ransom deadline set by the group. While the airline declined to comment on the report, it confirmed that the data release had occurred and emphasized ongoing efforts to contain the situation.
Qantas noted that an injunction is in place to prevent stolen data from being accessed, viewed, transmitted, or otherwise used by third parties. However, experts caution that once data is published on the dark web, it can quickly circulate across multiple platforms, making containment difficult.
Risks for Customers
The exposed information due to the Qantas Data Breach, could be leveraged for phishing schemes, social engineering attacks, and identity theft attempts. While the airline has indicated that payment details and login credentials were not accessed, the combination of personal identifiers such as names, addresses, and contact information can still be valuable for cybercriminals.
Cybersecurity professionals recommend that affected individuals monitor their accounts carefully and verify any communications claiming to be from Qantas or related services. Hackers often use leaked personal information to craft highly targeted and convincing scams.
Response and Investigation
Qantas has emphasized its commitment to working with cybersecurity specialists to understand the scope of the data release. The airline continues to support affected customers and has stated that no frequent flyer account credentials or financial information were compromised.
The Qantas Data Breach highlights the ongoing challenges airlines and other large organizations face in protecting customer data, particularly when third-party systems are involved. Companies are increasingly investing in monitoring, threat detection, and incident response capabilities to mitigate risks associated with such attacks.
The airline’s statement underscored the importance of robust cybersecurity practices and transparent communication with customers when breaches occur. Ongoing monitoring and engagement with cybersecurity experts are crucial to preventing further misuse of compromised data and reducing the impact on affected individuals.
The Qantas Data Breach serves as a reminder of the vulnerabilities inherent in digital systems and the growing sophistication of cybercriminal groups targeting personal data across multiple sectors.
