# Amadeus iHotelier

Data breach — Moderate

Amadeus iHotelier, a booking engine used by numerous hotels for direct online reservations, suffered a security incident revealed in September 2026 through notifications sent by several client hotels to their own customers. 7Hotel & Spa (Illkirch-Graffenstaden) states that Amadeus confirmed unauthorized access to its customers' reservation data, while the German hotel group Maritim reported that reservation lists were stolen for stays scheduled between August 2026 and September 2027.

Combining identity, contact details and precise booking information makes fraudulent messages impersonating a hotel or the booking platform more convincing.

## Exposed data

- Full name
- Postal address
- Email address
- Phone number
- Customer ID
- Order history

## What you can do

- Expect phishing attempts quoting your name and this company. A message that knows your details is not legitimate for that reason.
- You can ask the organisation exactly what was exposed about you (right of access), and complain to the DPA if no answer comes within a month.
