How many

  • Hotel reservations 1,557 records

Who is affected

  • Hotel reservation holders

Cause

Unauthorized access to the external reservation platform used for hotel bookings (Amadeus IT Group, S.A.)

Timeline

  1. First disclosure

Response

  • Phishing warning

Warned customers not to open links in suspicious emails or SMS, and advised that the hotel will never ask for additional payment via messages or similar means

What you should do

  1. Don't open links in emails from this company. The apology email itself may be fake
  2. Treat refund or apology calls and texts as scams. Call back only on the number from the official site
  3. Check the company's notice to see if you're affected

Lessons for companies

  1. Put security requirements, audit rights and reporting deadlines in vendor contracts
  2. Report to the PPC: preliminary in 3–5 days, final in 30 (60 if malicious)
  3. Run red teaming and AI-assisted hardening, and publish how much you invest
