The astonishingly high number came to light on the heels of a study recently published by Cyber security firm, Symantec Corporation and researcher Candid Wueest.
According to the report, 2 out of 3 hotels are “…inadvertently leaking booking reference codes to third-party sites such as advertisers and analytics companies.”
Wueest further notes that the information shared could allow “…these third-party services to log into a reservation, view personal details, and even cancel the booking altogether.”
Details being leaked include:
- Full name
- Email address
- Passport number
- Phone number
- Last four digits of credit card plus the card type & expiration date (yikes!)
The study involved an analysis of around 1500 hotels in more than 50 countries.
