Exposed airline booking details could be used to carry out convincing scams and other forms of fraud, cybersecurity experts say. Here's what passengers should know and how they can protect themselves.

SINGAPORE: Around 46,000 Singapore Airlines (SIA) booking records were recently accessed in a data breach involving its software provider Amadeus.

The exposed information included passengers' names, booking references and travel itineraries, while some records may also have contained contact details and KrisFlyer membership numbers.

But what can cybercriminals do with such information, even without access to passwords or credit card details?

CNA asked cybersecurity experts about how stolen airline booking records could be misused, whether similar incidents have occurred before and what affected passengers can do to protect themselves.

According to a media statement by SIA on Tuesday (Nov 3), the data accessed during the breach included passengers' names, booking reference numbers, travel itineraries and booking classes.

For around 620 of the affected records, additional information such as email addresses, phone numbers, travel document details and KrisFlyer membership numbers may also have been accessed.

Airline booking records can contain a range of other information, depending on how a trip was arranged.

According to Amadeus' website, such records may include cabin classes, departure and arrival airports, as well as supplementary services booked through travel agents, such as hotel stays, airport transfers and rental cars.
