The FBI has issued an urgent warning that Scattered Spider, a notorious cybercrime group, is increasingly targeting the U.S. aviation sector using highly deceptive social-engineering tactics to bypass security systems.
Sophisticated MFA Bypass and Help Desk Manipulation By Scattered Spider
Scattered Spider gained notoriety in 2023 after breaching major casino chains like MGM Resorts and Caesars Entertainment. Its current strategy focuses on impersonating employees or IT contractors to trick help desk staff. They target multi-factor authentication (MFA) protocols—sometimes deploying “MFA fatigue” attacks—to insert unauthorized devices into corporate accounts and gain persistent access.
According to the FBI, the group also exploits third-party IT service providers tied to airlines. These attacks often involve registering new MFA tokens or resetting credentials. Once inside, the group installs remote access malware, exfiltrates data, and holds organizations to ransom.
Cybersecurity firms Mandiant and Unit 42 confirm that several airlines and airports have experienced incidents consistent with Scattered Spider’s methods. Mandiant’s Charles Carmakal highlights how attackers exploit help desk procedures to add phone numbers or devices—classic social-engineering playbooks. Similarly, Unit 42 urges all aviation organizations to scrutinize MFA reset requests and strengthen identity checks.
Immediate Steps and Industry Recommendations
The FBI recommends several defensive measures:
- Tighten help desk identity verification before approving MFA changes or password resets
- Segment vendor access from core airline systems
- Monitor for suspicious MFA resets and unusual device additions
- Train staff to recognize help desk impersonation, phishing emails, and fake support calls
These steps aim to reduce the risk of social-engineering attacks, which often slip past standard cybersecurity tools.
As Scattered Spider evolves its tactics, the aviation sector must adapt its security posture accordingly. Strengthened identity verification and vigilant IT practices could prevent high-impact breaches and protect sensitive data across the industry.
