The FBI has warned that the Scattered Spider cybercriminals are now targeting US airlines and transportation, following attacks on UK retailers in the past.
The group, known for causing system outages and deploying ransomware, consists of financially motivated young adults using phishing and social engineering techniques.
Two airlines, Hawaiian Airlines and Canada's WestJet, reported cyber incidents in June 2025, potentially linked to Scattered Spider's activities.
The FBI advises vigilance for anyone in the airline ecosystem, as the group could target direct organizations or breach supply chain third-parties for access.
