Hotel Koldingfjord ( https://www.koldingfjord.dk/vigtig-information ) is one of a number of Danish hotels affected by a data leak at the supplier of the software that handles guest reservations and more.

Guests have received a message via the WhatsApp messaging service asking them to enter their card details.

But the message is fake, as Hotel Koldingfjord does not use WhatsApp at all when communicating with guests, the hotel writes in a Facebook post. ( https://www.facebook.com/hotelkoldingfjord/posts/pfbid02F4uEfNsSa5xa2Y9JAozMSSc8vJPYfYwLAQUw9dm1syLhhPBQrjEDWz9BhQdHJuEkl )

One guest clicked on the message

The hotel's director, Peder Madsen, says they have been in contact with a guest who accidentally clicked on the message.

- We have had a single customer who apparently entered their credit card number but did not proceed to MitID. We advised that customer to contact their bank and card company, he says.

Fortunately, the vast majority of customers did not get that far, but several have contacted the hotel.

- At this point, we have received 25 inquiries from customers who have called us to ask about it. We have given them a thorough explanation, and we will contact them again, he promises.

Several hotels affected

According to TVSyd ( https://www.tvsyd.dk/syd-og-soenderjylland/schackenborg-slotskro-advarer-gaester-flere-hoteller-ramt-datalaek-f7503 ), Hotel Koldingfjord is one of several affected by the data leak. The outlet reports on four other hotels in southern Jutland that have experienced something similar.

The company that handles the hotels' reservations and was subject to the data leak writes on their operational status page ( https://techotel.dk/driftinfo/ ) that they are working on the matter, and it appears the leak was detected on Saturday afternoon.

In Kolding, Peder Madsen hopes and believes the leak will be handled, as the hotel is in close contact with the system supplier. But he is prepared for the fact that this weekend's situation is unlikely to be the last.

- Our system supplier is working hard to figure out what happened – and of course to prevent a similar situation in the future. But the world we live in is a place where these things happen, he says.
