"We are planning at the next room refurbishment for old-fashioned
     door locks with real keys," he said. "Just like 111 years ago at the
     time of our great-grandfathers."

   Hackers Disable Door Locks at Four-Star Hotel, Demand Ransom
   The hackers demanded 2 Bitcoins in payment to return control of the
   systems back to the hotel -- and the hotel says it had no choice but to
   pay.

   Hackers recently breached the internal systems at Austria's four-star,
   111-year-old Romantik Seehotel Jagerwirt, according to Bleeping
   Computer.
   The hackers disabled both the hotel's electronic door locks and the
   reservation system, meaning that new keys couldn't be generated and
   reservations couldn't be checked or confirmed.
   They demanded 2 Bitcoins (almost $2,000) to return control of the
   systems back to the hotel -- and the hotel says it had no option but to
   pay the ransom.
   "The house was totally booked with 180 guests, we had no other choice,"
   hotel managing director Christoph Brandstaetter told The Local.
   "Neither police nor insurance help you in this case."
   This was the third recent cyber attack for the hotel, Brandstaetter
   said. A fourth attempt soon after was only blocked because computers
   had been replaced and new security standards implemented.
   "The restoration of our system after the first attack in summer has
   cost us several thousand Euros," Brandstaetter said. "We did not get
   any money from the insurance so far because none of those to blame
   could be found."
   In response to the hack, Brandstaetter said the hotel has one unique
   security solution in the works. "We are planning at the next room
   refurbishment for old-fashioned door locks with real keys," he said.
   "Just like 111 years ago at the time of our great-grandfathers."
   According to the results of a recent 451 Research survey of almost
   1,000 enterprise IT buyers worldwide, 50 percent of respondents said
   security is the top impediment for IoT deployments.
   Still, enterprises are moving ahead with IoT initiatives, with 90
   percent of enterprises planning to increase IoT spending over the next
   year.
   Respondents' mean IoT-related spending is expected to increase by 33
   percent over the next 12 months.
   While 54 percent of respondents said a lack of trained IoT staff is not
   an issue for their organizations, 46 percent said they're having
   difficulty filling IoT-related positions.
   "When it comes to IoT adoption, pragmatism rules," 451 Research
   director Laura DiDio said in a statement. "The survey data indicates
   enterprises currently use IoT for practical technology purposes that
   have an immediate and tangible impact on daily operational business
   efficiencies, economies of scale and increasing the revenue stream."
