An unprotected, internet-facing Advance Passenger Information System (APIS) database, reportedly managed by Vietnam-linked entities, has exposed approximately 220.8 million records. The breach encompasses highly sensitive datasets including full legal identities, passport numbers, flight itineraries, and crew records spanning from January 2017 to April 2026. The lack of access controls allowed unauthorized access to a centralized repository of international travel data. This exposure presents critical risks of large-scale identity theft, passport forgery, and targeted espionage via the physical tracking of high-value passengers and aviation personnel.
