A hotel was locked out of its key system by ransomware. From the sounds of it, the ransomware encrypted the file used maintain the key system, rendering it useless and unable to issue new keys.
This is likely to be the way things go as more devices connect to the internet one way or another. In this case it probably an excel file that the key program used as a parking space for the key codes(note to programmers, use your own file formats for stuff like this). In any case the hotel was locked out of their own key system because the master file was encrypted. I hope that it was only the key system as I can imagine if the same program were sued for room charges and such, all operating out of the same excel spreadsheet. Ultimately, I suspect that any computer that handles key business functions, let alone security will have to be set up so that the system doesn’t talk to the net at all. That’s the only real way to keep ransomware from trashing your business just because somebody clicked on an invoice that they didn’t realize was fake.
Here’s the week in ransomware.
