Update: Hawaiian Airlines cyberattack has marks of Scattered Spider, sources say

Multiple aviation-sector cyberattacks—most recently impacting Hawaiian Airlines and earlier WestJet—are likely the work of the Scattered Spider criminal group (UNC3944). Industry responders (Mandiant, Palo Alto Networks) and the FBI report similar incidents across the airline and transportation sector and recommend immediate hardening measures such as robust identity verification for help desks and phishing-resistant MFA.
