Executive Summary
In 2025, the actor group Scattered Lapsus$ Hunters compromised Vietnam Airlines data held in its Salesforce environment and published a 63GB dataset on 10 October 2025. The leak spanned more than 23 million records, with an independent parse identifying about 7.4 million unique email addresses and 8.1 million unique phone numbers, alongside names, dates of birth, and loyalty-program (frequent-flyer) identifiers.
ObscureIQ assessment: Exposure enables travel fraud, phishing, booking impersonation, and physical-world targeting. Itinerary and loyalty data can also reveal movement patterns and periods when travelers are away from home.
Breach Impact
The identity and loyalty data supports targeted phishing and account-takeover attempts against travelers, and inclusion in the wider Salesforce campaign means the same actor holds comparable data on many other brands.

Vietnam Airlines is the flag carrier of Vietnam, operating domestic and international flights and a frequent-flyer loyalty program.
Why They Hold Your Data

Recent Developments
In October 2025, Scattered Lapsus$ Hunters published a Vietnam Airlines dataset they said was taken from the airline’s Salesforce environment earlier in the year, part of a broader campaign against Salesforce customers.
