PARIS — An Austrian luxury hotel says it’s ditching electronic room cards for old-fashioned locks and keys after having their systems frozen by blackmail-hungry hackers.

The husband-and-wife management of Romantik Seehotel Jaegerwirt, in the Austrian Alps, says that one recent infection with ****** software resulted in the complete shutdown of hotel computers.

They say they were forced to pay roughly 1,500 euros (nearly $1,600) worth of electronic currency to restore their network.

Several publications incorrectly reported that the ransomware infection resulted in guests being locked into or out of their rooms.

In a series of emails, the hotel said Tuesday that the infection only resulted in new guests being temporarily unable to get keys to their rooms.

Hotel co-manager Christina Brandstaetter says the new arrivals were treated to champagne while they waited.
