The FBI and cybersecurity firms have warned that a hacking group known as Scattered Spider is targeting airlines and the transportation sector.
Scattered Spider, comprised mainly of financially motivated English-speaking hackers, uses tactics like social engineering, phishing, and ransomware to steal data.
The hackers may target large corporations and their IT providers in the airline ecosystem, putting airlines and associated vendors at risk.
Recent intrusions have been reported by Hawaiian Airlines and WestJet, with the latter's cyberattack linked to Scattered Spider. This follows previous attacks on the retail sector and insurance industry.
