Hawaiian Airlines, a subsidiary of Alaska Air Group, announced a significant cybersecurity event on June 26, 2025. Although flight disruption was avoided, the incident exposed weaknesses in airline IT systems, sparked concerns over passenger data protection, and raised questions about aviation cybersecurity best practices.
What We Know So Far
Firstly, the breach was first reported by Hawaiian Airlines officials, who confirmed an “IT systems incident” but emphasized that flight schedules remained on time and that safety and operations were unaffected. They later revealed that federal agencies, including the FBI, CISA, and FAA, along with professional cybersecurity firms, are assisting with incident response and containment efforts.
Who Might Be Behind It
Cybersecurity experts are aggressively investigating whether the notorious Scattered Spider hacking group—also known as UNC3944—is responsible. This group is notorious for social engineering, MFA bypass, and airline system intrusion, specifically targeting help-desks and reservation systems. Increased risk is highlighted by previous cyberattacks on other carriers like WestJet, Japan Airlines, and Alaska Airlines, suggesting a pattern of threats across the industry.
Systems Affected—but Services Remain Uninterrupted
While flight bookings and airport operations continued, internal functions—such as customer data services, ticketing platforms, and frequent flyer systems—may have been compromised. The airline stressed that passenger-facing channels were secure, but admitted that some back-end systems are undergoing maintenance and restoration.
Why This Matters for Travelers
This event raises concerns regarding passenger personal data safety, from passport numbers and payment information to loyalty program profiles. Such sensitive content makes airlines prime cyberattack targets, often sought after by fraud rings, phishing campaigns, and financial criminals.
What Hawaiian Airlines Is Doing Now
Their response includes:
- Engaging federal cybersecurity agencies—FBI, CISA, FAA—to aid in real-time investigation and encryption protocols (reddit.com).
- Deploying third-party cybersecurity teams to evaluate networks, investigate possible data exfiltration, and restore affected systems.
- Communicating updates to customers through official statements, urging vigilance, and password changes for impacted systems.
Passenger Steps to Stay Secure
Travelers should:
- Monitor reservation and frequent flyer account activity.
- Use strong, unique passwords, and enable multi-factor authentication.
- Stay alert for phishing attempts alleging reservation or account issues.
- Verify communications via the official Hawaiian or Alaska Airlines website.
- Regularly review credit and bank statements for suspicious charges.
Industry-wide Cybersecurity Implications
This incident underscores that aviation-level cyber hygiene, including real-time threat detection, legacy system patching, and employee phishing training, is no longer optional. As cybercriminals adapt, airlines must prioritize:
- Zero-trust architectures, encrypting internal communications and limiting access.
- Frequent security audits, including penetration testing and air-gapped backups.
- Regulatory compliance, with possible FAA or DOT mandates tied to passenger data protection.
- Cross-industry collaboration for shared threat intelligence and exchange of incident mitigation strategies.
