I keep receiving scam emails from a hotel I booked on booking.com (see Booking.com customers targeted by scam ‘confirmation’ emails — The Guardian). I warned the hotel last week and still get those messages every day. Obviously the security of their devices is compromised and they aren't doing much about it. I am coming tomorrow to this hotel (in Spain), and they are gonna ask me for my passport and other details. I cannot trust that my personal data will be kept safe. What can I do?
To @Berend: my understanding is that hotels get infected by a malicious email attachment and they get their booking.com credentials stolen (https://www.telegraph.co.uk/money/consumer-affairs/booking-customers-details-sold-dark-web-hotels-hacked/). I suppose their device is completely compromised after clicking the attachment.
