The vulnerability of the burgeoning IoT networks was exposed in one of Europe’s largest luxury hotels when hackers managed to lock all its doors remotely. Guests were reported to be locked out of their rooms (though presumably some were locked in as well) at the Romantik Seehotel Jaegerwirt in the Alps.
The hackers demanded a ransom of €1,500 to reactivate the locks and the hotel acceded to the demand, paying the ransom in Bitcoin. The decision was presumably influenced by the fact that it was the height of the tourist season.
Unfortunately for the hotel the hackers had no scruples and hacked the locks a further two times.
For the hotel this is the end of the line and they will be getting rid of the electronic locks.
“We are planning at the next room refurbishment for old-fashioned door locks with real keys,” management said. “Just like 111 years ago, at the time of our great-grandfathers.”
