(NEXSTAR) – A cybercrime organization known as “Scattered Spider” has been targeting airlines based in North America in recent weeks, attempting to gain access to sensitive data for purposes of extortion, the FBI confirmed in an alert issued Friday.

“They 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,” the alert reads, in part.

How have airlines or customers been affected?

A number of major airlines have confirmed security breaches in recent weeks, including Canada’s WestJet, which reported a “cybersecurity incident” in mid-June. The incident affected internal systems, but the carrier also warned that some customers may find themselves “restricted” from the app, or noticing “interruptions or errors” on the app or website. It was unclear if the customer-facing issues were the result of the cyberattack or the carrier’s attempts to fix or mitigate the issue.

A representative for WestJet was not immediately available for comment.
