Research: If you book hotels, your data may have leaked

dataNew research reveals that two-thirds of hotels websites leaked customer reservation data.

Last November, it was discovered that data from 500 had been leaked to millions of customers at Marriott International. However, guests of other hotels should also be concerned.

The Symantec security electronics company did a survey on 1.500 websites hotels, in 54 countries. The hotels were two to five stars. What the survey found was that two out of three sites did not protect personal information and customer booking data, so they leaked to companies dealing with statistics and advertising agencies.

As it turned out, this is due to the fact that hotels use a link in the confirmation emails they send to customers, which leads directly to the reservation without requiring authentication. This means that whoever has it URL link will be able to access customer data. By the way, they have access to data, statistics and advertising companies, as sites include their content. It seems to be a very common practice, since, according to the survey, it was found in 57% of the hotels examined.

We all know, even if we do not like it, that advertising companies are watching our online habits. However, in this case it goes one step further, as they can log in to our booking, see very personal information, and even change or cancel the reservation.

Also, according to research, many sites are at risk of brute-force attacks by which hackers, using special machines, can easily access various data even when booking an entire hotel chain.

Surveyor Candid Wueest said he briefed all the hotels he had found on the above issues and that 25% of the hotel's personal data protection officers did not respond. Responders did it on average, in ten days. On the other hand, there were some hotel representatives who said their privacy policy allowed them to share customer data with advertisers.
