These US airlines were targeted by cyber hackers this month
Hackers are targeting U.S. airlines as the FBI issued an alert Friday about a notorious cybercriminal group.
So far, at least two U.S. airlines have been affected by cyberattacks, though the details of the impact of the incidents were not clear.
WestJet and Hawaiian Airlines have both been victims of cyberattacks recently.
The FBI singled out Scattered Spider in an alert Friday, in which the bureau said the group was โexpanding its targeting to include the airline sector.โ
Scattered Spider was linked to the hacking and extortion of Caesars Entertainment and MGM Resorts International in 2023, which led the former to pay a ransom of approximately $15 million.
Hackers were able to access a significant number of driverโs license numbers and possibly even Social Security numbers of the casino customers through the ransomware demand.
โThese actors rely on social engineering techniques, often impersonating employees or contractors to deceive IT help desks into granting access,โ the FBI alert said.
โThey target large corporations and their third-party IT providers, which means anyone in the airline ecosystem, including trusted vendors and contractors, could be at risk,โ the warning continued. โOnce inside, Scattered Spider actors steal sensitive data for extortion and often deploy ransomware.โ
The chief technology officer of Googleโs cloud security company, Mandiant, warned the industry to โtake steps immediately to harden systems.โ
WestJet said it had made โsignificant progressโ to resolve a hack it suffered earlier this month.
Hawaiian Airlines told the Securities and Exchange Commission it discovered its hack on Monday.
โOn June 23, 2025, Hawaiian Airlines, an Alaska Air Group, Inc. subsidiary, identified a cybersecurity incident affecting certain information technology systems,โ the company said in a filing. โUpon learning of this event, we immediately took steps to safeguard Hawaiianโs operations and systems. Flights are currently operating safely and as scheduled.โ
The Federal Aviation Administration told Reuters it was in contact with Hawaiian Airlines. โThere has been no impact on safety, and the airline continues to operate safely. We are monitoring the situation,โ the agency said.
