Artificial intelligence can further amplify fraud that relies on such data. What should travel agencies verify?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Today, travel bookings rarely remain within a single system. Passenger data pass through airlines, GDSs, hotel platforms, online booking systems, CRM applications and external technology partners. In the process, a security issue at one participant can affect customers of other companies, even though their own networks have not been breached.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two recent cases illustrate different types of exposure: unauthorised access to reservation data in the Amadeus environment and an attack via an external technology supplier which, according to Expedia Group, enabled access to its systems. These are not proof that AI was used in those incidents. <a href=\"https:\/\/tragento.com\/en\/ai-for-travel-agencies-time-savings-and-the-role-of-agents\/\" data-type=\"post\" data-id=\"12717\">AI is separate<\/a>, a growing factor that can increase the credibility and scale of subsequent frauds.<\/p>\n\n\n\n<h2 id=\"h-sto-je-potvrdeno-u-slucajevima-amadeusa-i-expedije\" class=\"wp-block-heading\">What was confirmed in the cases of Amadeus and Expedia?<\/h2>\n\n\n\n<div style=\"display:flex;flex-wrap:wrap;gap:14px;margin:22px 0;font-family:inherit\">\n<div style=\"flex:1 1 260px;min-width:0;border-top:5px solid #3AD0E6;background:#F5F3EE;padding:22px;border-radius:8px;color:#111111\"><div style=\"font-size:13px;font-weight:700;letter-spacing:.08em;text-transform:uppercase\">Amadeus \u00b7 October\/November 2026.<\/div><h3 style=\"font-size:22px;line-height:1.25;margin:11px 0\">Booking information<\/h3><p style=\"margin:0 0 12px\">Airlines have reported unauthorised access to reservation data stored in Amadeus's system. Those affected include Cathay Pacific, Singapore Airlines and Japan Airlines.<\/p><p style=\"margin:0;font-size:14px\"><strong>Confirmed:<\/strong> names, PNR codes and travel details; for a smaller subset of records, additional personal data. There is no evidence of access to payment data in the aforementioned disclosures.<\/p><\/div>\n<div style=\"flex:1 1 260px;min-width:0;border-top:5px solid #111111;background:#F5F3EE;padding:22px;border-radius:8px;color:#111111\"><div style=\"font-size:13px;font-weight:700;letter-spacing:.08em;text-transform:uppercase\">Expedia Group \u00b7 12 November 2026.<\/div><h3 style=\"font-size:22px;line-height:1.25;margin:11px 0\">Supplier attack<\/h3><p style=\"margin:0 0 12px\">Expedia has confirmed that attackers gained access to its systems via a compromised data technology provider.<\/p><p style=\"margin:0;font-size:14px\"><strong>It has not yet been confirmed:<\/strong> the scope of potentially exposed data, the identity of the supplier and the link to other publicly described incidents.<\/p><\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/tragento.com\/en\/category\/aviation-industry\/\" data-type=\"category\" data-id=\"95\">Cathay Pacific<\/a> announced that approximately 53,000 bookings were affected, and Singapore Airlines around 46,000 booking records. Japan Airlines reported data for approximately 92,000 passengers. In the case of Cathay Pacific, unauthorised access via system credentials, according to the airline's notice, covered the period from August 2023 to September 2026. It should be distinguished between the compromise of a specific reservation environment and the claim that the entire Amadeus GDS is compromised \u2014 there is no confirmation for such a broader conclusion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At Expedia, the threat from a supplier who has already been granted access is particularly significant. If their credentials are compromised or old privileges remain active, an attacker could inherit access to another company. Research related to the Qubole platform provides a useful example of such a pattern, but it has not been publicly confirmed that this case is directly linked to the Expedia incident.<\/p>\n\n\n\n<h2 id=\"h-kako-jedan-kompromitirani-pristup-postaje-problem-za-putnika\" class=\"wp-block-heading\">How does compromised access become a problem for the traveller?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The following diagram shows <strong>possible chain of risk<\/strong>, and not a reconstructed sequence of any of the listed incidents. The attack does not have to go through all the steps shown.<\/p>\n\n\n\n<div role=\"img\" aria-label=\"Scheme for the possible transfer of risk from the technology supplier, via the reservation systems and the travel agency, to the passenger.\" style=\"border:1px solid #d4dde0;border-radius:10px;padding:20px 15px;background:#fff;margin:18px 0 8px;color:#111111\">\n<div style=\"font-weight:800;font-size:13px;letter-spacing:.08em;text-transform:uppercase;margin-bottom:14px\">Illustrative chain of risk<\/div>\n<div style=\"display:flex;flex-wrap:wrap;align-items:stretch;gap:8px;justify-content:center;text-align:center\">\n<div style=\"flex:1 1 155px;padding:16px 10px;background:#111111;color:#fff;border-radius:8px\"><strong>1.

It does not imply that all the actions shown took place in the Amadeus or Expedia incidents.<\/p><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Even without the credit card number, the combination of name, booking reference and travel date can be valuable to criminals. A message quoting the actual flight number and requesting immediate confirmation of the booking appears far more convincing than a generic spam email. Depending on each carrier's security measures, the PNR and surname can reveal additional booking details or enable certain actions.<\/p>\n\n\n\n<h2 id=\"h-gdje-u-cijelu-pricu-ulazi-umjetna-inteligencija\" class=\"wp-block-heading\">Where does artificial intelligence fit into the whole story?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Generative AI can help compose grammatically convincing messages in different languages, tailor scams to a specific journey, imitate voices, and automatically analyse vulnerabilities. In its 2026 threat outlook, ENISA warns that new AI models will increasingly serve as support for malicious operations. This does not mean that AI is the cause of the confirmed incidents at Amadeus and Expedia, but that stolen data could become even more useful for the next stage of an attack.<\/p>\n\n\n\n<div style=\"padding:22px;background:#e1faff;border-left:6px solid #3AD0E6;border-radius:7px;margin:22px 0;color:#111111\"><div style=\"font-size:12px;letter-spacing:.1em;text-transform:uppercase;font-weight:800;margin-bottom:10px\">Example of a possible scam \u00b7 not a real message<\/div><p style=\"font-size:17px;line-height:1.5;margin:0 0 10px\"><strong>\u201eYour flight to Frankfurt tomorrow has been changed.

In certain cases, the GDPR requires a breach to be reported to the competent authority, generally no later than 72 hours after becoming aware of it when there is a likely risk to individuals' rights and freedoms. In the event of high risk, it may also be necessary to notify the affected individuals. Specific obligations depend on the circumstances and the agency's role in data processing.<\/p>\n\n\n\n<h2 id=\"h-sigurnost-podataka-treba-postati-kriterij-pri-izboru-dobavljaca\" class=\"wp-block-heading\">Data security should become a criterion when selecting suppliers.<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Travel agencies traditionally compare the prices, content, support and functionalities of GDS, hotel platforms and booking engines. Security issues deserve the same attention: who has access to reservations, how long is the data retained, how are third-party partners' permissions managed and how quickly does the supplier notify you of an incident?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most practical starting point is not to purchase yet another tool, but to review accounts, access rights, integrations and payment procedures. In an agency that manages sensitive passenger data on a daily basis, a single neglected credential can create a problem far greater than the technical incident itself.<\/p>","protected":false},"excerpt":{"rendered":"<p>Sigurnosni incidenti povezani s Amadeusom i Expedijom otvaraju pitanje koliko su rezervacijski podaci putnika za\u0161ti\u0107eni kada prolaze kroz mre\u017eu tehnolo\u0161kih dobavlja\u010da.
