What Lessons did we Learn from the Qantas Cyber-Attack?
Introduction
Imagine waking up to news that your airline loyalty data — including your birthdate, phone number, and email — has been exposed to cyber criminals. That was the reality for nearly six million Qantas customers in one of the most significant data breaches Australia has seen in recent years. While Qantas acted swiftly, the attack revealed vulnerabilities that all organisations must learn from.
This wasn’t just an IT failure. It was a stark reminder that cybersecurity is no longer just a “tech issue” — it’s a boardroom conversation. So, what lessons can we pull from the Qantas breach?
The Anatomy of the Qantas Breach
What happened
In early 2025, Qantas revealed that a major data breach occurred through a third-party call centre in Manila. Attackers used vishing — voice phishing — to impersonate an employee and gain access to a customer support platform. The result? Millions of records were compromised.
Where the breach Originated
This wasn’t a direct breach into Qantas’ main systems. Instead, it came via a third-party contractor responsible for handling customer service. Once inside, the attackers had access to sensitive data.
Data Compromised
Though no financial information or passwords were stolen, attackers accessed:
- Full names
- Dates of birth
- Phone numbers
- Email addresses
- Frequent flyer membership numbers
Lesson 1: Third-Party Risk Management cannot be Ignored
The Call Centre Vulnerability
Outsourcing customer service to international vendors is cost-effective, but comes with risks. In this case, a third-party call centre became the weakest link.
Due Diligence and Vendor Oversight
It’s not enough to trust partners with sensitive data. Organisations must:
- Audit vendors regularly
- Mandate cybersecurity compliance standards
- Include breach notification clauses in contracts
Examples of better Third-Party Practices
Leading companies conduct annual third-party risk assessments, require vendors to use zero-trust architectures, and ensure all third-party users go through security awareness training.
Lesson 2: Human Error is still Cybersecurity’s weakest link
Vishing and Social Engineering
The attacker didn’t “hack” the system — they tricked someone. This is what makes social engineering so dangerous. A clever script and some convincing language gave the attacker what they needed.
Why Training is your first line of defence
Organisations must implement:
- Regular phishing simulations
- Role-specific security awareness training
- Gamified learning to engage employees
How often should training be Refreshed?
Quarterly refreshers are ideal. Cyber threats evolve, so should your people’s knowledge.
Lesson 3: MFA helps but is not Bulletproof
What MFA can and cannot Protect
Qantas had MFA in place for frequent flyer accounts, which prevented full account takeovers. However, MFA alone didn’t stop the breach because attackers targeted backend systems.
The Importance of Layered Security Models
MFA should be just one layer in a broader strategy that includes:
- Network segmentation
- Behavioural analytics
- Endpoint Detection and Response (EDR)
Lesson 4: Communication is Key During a Crisis
How Qantas Responded
To their credit, Qantas quickly informed customers, collaborated with government cyber teams, and issued public statements. Speed matters in breaches.
Why Customer trust depends on Transparency
Being honest with customers, even about bad news, builds long-term loyalty. Delay or cover-up will only backfire.
Best Practices for Breach Disclosure
- Notify affected individuals within 72 hours
- Provide clear guidance on next steps
- Offer identity protection services if necessary
Lesson 5: Legal Liability Extends to Third-Party Breaches
Qantas Accountability
Even though a third-party caused the breach, the public holds Qantas responsible — and rightfully so. Legal frameworks like the Australian Privacy Act demand accountability.
The Role of Data Privacy Regulations
Companies must ensure vendors adhere to local data laws, even if operations are offshore.
Australian Privacy Act and Implications
This breach could lead to penalties under the Notifiable Data Breaches (NDB) scheme, where organisations must report any breach likely to cause serious harm.
Lesson 6: Learning From Cyber Incidents is Critical
Qantas’ Response and Upgrades
Post-incident, Qantas began working with external cybersecurity experts to harden their systems, review third-party policies, and rebuild public trust.
Incident Response Maturity Models
Organisations should have a tested incident response plan that’s updated annually and aligned with frameworks like NIST or ISO 27001.
How this breach impacts the Airline and Travel Industry
Industry-Wide Implications
Airlines handle mountains of personal data — from passports to itineraries. This incident has sent shockwaves through the entire travel sector.
Travel data as a High-Value target
Frequent flyer accounts, travel patterns, and ID details are goldmines for cybercriminals, often sold on the dark web.
Conclusion: Stay Aware, Stay Secure
The Qantas cyber-attack isn’t just a headline — it’s a wake-up call. Whether you’re running a small business or a multinational airline, the lessons here are universal. Protect your data. Educate your people. Monitor your vendors. And when something does go wrong, own it, fix it, and learn from it.
Cybersecurity isn’t a one-time fix — it’s an ongoing commitment.
