GovInfoSecurity @prajeetspeaks) • March 5, 2021 Photo: Malaysia Airlines An aviation IT company that says it serves 90% of the world's airlines has been breached in what appears to be a coordinated supply chain attack. Customers of at least four companies - Malaysia Airlines, Singapore Airlines, Finnair Airlines and Air New Zealand - may have been affected by the incident. The Switzerland-based IT company, SITA, says passenger data stored on its SITA Passenger Service System server in the U.S. was stolen. Earlier this week, Malaysia Airlines confirmed personal information belonging to members of its frequent-flyer program, Enrich, was compromised over a nine-year period, tying the incident to its IT service provider, but not naming SITA.
