The Trump Hotels website is displaying a “Checking your browser before accessing Trumphotels.com” notification upon loading the page—a strong indication the site is in full defense mode against distributed denial-of-service (DDoS) attacks.

Trump Hotels was successfully attacked twice in a span of six months last year. Hackers were able to place malicious software on the hotel’s payment system and gain information on anyone who visited the chain between May 2014 and June 2015.
The hotel chain seems to have beefed up its cybersecurity efforts with help from internet security services company CloudFlare.
We have reached out to Trump Hotels for comment on any DDoS attacks on its website. We will continue to update this story as we gain more information.
