Two Thirds of the Hotels Give Your Personal Data to Third Parties


The hotel sector suspends in terms of privacy: two out of three hotel websites inadvertently filter reservation data and other personal information from guests to advertisers and other companies according to a study.

Two out of three hotel websites inadvertently filter reservation data and other personal information from guests to third parties, such as advertisers and consultants or analysts, according to a study by security firm Symantec.


"While it is no secret that advertisers are tracking the browsing habits of users, in this case, the shared information could allow these third-party services to log in to a reservation, see personal data and even cancel the reservation in full ", The report details.

The study also notes that these vulnerabilities are often related to the confirmation emails of a reservation, which hotels send to our inbox. And, the reference code attached to the direct link to the reservation could be shared with more than 30 different service providers, including the main social networks, search engines (Google, Bing...) and advertising and analysis services.

This worrying finding, obtained after examining 1,500 web pages of hotels in 54 countries, confirms that this sector has not done the duties related to cybersecurity and user privacy. Especially if we bear in mind that one of the biggest data leaks in history was precisely the Marriott hotel chain.

But what is even more striking is that the hotels were not able to respond adequately when they have experienced a problem of this nature. According to Symantec, 25% of those responsible for data protection in hotels did not respond at least six weeks after notification of an incident, while those who did took an average of 10 days to realize the situation. .
