Federal Warning: Scattered Spider Cyberattacks Threaten North American Airlines
In late June and early July 2025, the FBI issued a high-priority warning to the aviation industry and the traveling public. The alert centers on a cybercriminal group called Scattered Spider, which has sharply increased its attacks on major airlines and their digital systems across North America. The warning follows a series of incidents that have raised concerns about the safety of airline operations, the privacy of passenger data, and the security of the entire aviation ecosystem.
Who is at risk? The FBI’s warning applies to all airlines, their employees, contractors, and even travelers who rely on digital airline services. The threat is not limited to one country; both United States ?? and Canada ?? have seen their airlines targeted, with WestJet Airlines and Hawaiian Airlines among the most recent victims.
What happened? In June 2025, WestJet Airlines in Canada ?? and Hawaiian Airlines in the United States ?? both reported cybersecurity incidents. These attacks did not disrupt flights, but they did affect internal systems and raised fears about possible data theft. The FBI responded by urging all airlines and related companies to be on “high alert” and to report any suspicious activity immediately.
Why does this matter? Airlines depend on complex digital systems for everything from booking tickets to managing flight operations. A successful cyberattack could cause major delays, expose sensitive passenger data, or even threaten flight safety if critical systems are compromised.
How are these attacks happening? Scattered Spider uses advanced tricks to fool airline employees and IT staff. They pretend to be real workers or contractors, tricking help desks into giving them access to important accounts. Once inside, they steal data, demand ransom, and sometimes shut down systems.
Let’s break down what’s happening, why it matters, and what travelers and the industry should do next.
Timeline of Recent Airline Cyberattacks
The FBI’s warning comes after a series of high-profile incidents in June and July 2025:
- June 13, 2025: WestJet Airlines reported a cybersecurity breach that affected its internal systems and mobile app. Some users could not access their accounts. The airline quickly started an investigation, brought in outside cybersecurity experts, and notified both customers and authorities. By June 18, WestJet said it had made progress in securing its systems, but the investigation was still ongoing.
- June 26, 2025: Hawaiian Airlines announced a “cybersecurity event” that hit some of its IT systems. The airline confirmed that flights were not affected. It worked with federal authorities and cybersecurity experts to address the problem.
-
June 27, 2025: The FBI posted a public alert on LinkedIn and X (formerly Twitter), warning the aviation industry to be on “high alert.” The agency encouraged early reporting of suspicious activity to help prevent further attacks.
-
July 1-5, 2025: News outlets and cybersecurity firms confirmed the FBI’s warnings. Experts shared their concerns about the risks and possible impacts for both travelers and the aviation industry.
How Scattered Spider Attacks Airlines
Scattered Spider is not a typical hacker group. It uses a mix of clever tricks and technical skills to break into airline systems. Here’s how they operate:
Social Engineering
- Impersonation: The group pretends to be real employees or contractors. They call or email IT help desks, using personal details to sound convincing.
- Credential Theft: Their main goal is to get the usernames and passwords of important staff, like system administrators or top executives.
- MFA Bypass: Even if accounts are protected by multi-factor authentication (MFA), Scattered Spider tricks help desks into adding new, unauthorized devices to these accounts. This lets them get in without the real user knowing.
Targeting Third Parties
- Expanding the Attack: Scattered Spider doesn’t just attack airlines directly. They also go after third-party IT providers, vendors, and contractors. This makes the entire airline ecosystem vulnerable.
Ransomware and Data Extortion
- Stealing Data: Once inside, the attackers steal sensitive data, such as customer information or business secrets.
- Ransom Demands: They often use ransomware to lock up systems and demand payment to unlock them. They may also threaten to release stolen data unless they are paid.
Rapid Escalation
- Quick Action: Experts say Scattered Spider can move very fast. Sometimes, they break in, set up their access, and launch ransomware attacks within just a few hours.
Impact on Airlines and Travelers
Operational Disruption
So far, the attacks on WestJet Airlines and Hawaiian Airlines have not caused flight delays or cancellations. However, experts warn that future attacks could be much worse. If hackers gain control of critical systems, they could cause widespread delays, data theft, or even threaten flight safety.
Data Privacy
As of July 5, 2025, neither WestJet Airlines nor Hawaiian Airlines has confirmed whether customer data was stolen. Investigations are still ongoing. However, the risk remains, and more victims may be identified as the situation develops.
Industry-Wide Threat
The FBI and cybersecurity experts stress that everyone in the airline industry is at risk—not just the airlines themselves, but also their vendors and contractors. The Federal Aviation Administration (FAA) is monitoring the situation and staying in contact with affected airlines.
Expert Perspectives: Why Airlines Are Vulnerable
Cybersecurity Experts
Kelly Siegel from National Technology Management and Sam Rubin from Palo Alto Networks Unit 42 point out that airlines are especially vulnerable because they rely on many connected digital systems. Scattered Spider’s social engineering tactics are very hard to defend against because they target people, not just computers.
Aviation Professionals
Captain Dennis Tajer from the Allied Pilots Association warns that cyberattacks could disrupt the flow of information between aircraft, pilots, and operations centers. This could lead to delays and confusion, even if flights are not directly affected.
Cybersecurity Firms
Google-owned Mandiant and Halcyon, two leading cybersecurity firms, say that Scattered Spider uses a “hybrid threat model.” This means they blend social engineering (tricking people) with technical hacking skills. The group is loosely organized, making it hard for law enforcement to shut them down.
FBI Recommendations for the Aviation Sector
The FBI has issued several key recommendations to help airlines and related companies protect themselves:
- Be alert for suspicious MFA reset requests and social engineering attempts.
- Report incidents immediately to the local FBI office. Quick reporting helps law enforcement respond and share information with others.
- Review and strengthen IT help desk protocols, especially for managing MFA devices and resetting credentials.
- Engage third-party cybersecurity experts for forensic analysis and to help fix any problems if an incident is suspected.
