Ransomware Infects a Hotel's Key System (dailymail.co.uk)
An anonymous reader writes:
A luxury hotel "paid "thousands" in Bitcoin ransom to cybercriminals who hacked into their electronic key system. The "furious" hotel manager says it's the third time their electronic system has been attacked, though one local news site reports that "on the fourth attempt the hackers had no chance because the computers had been replaced and the latest security standards integrated, and some networks had been decoupled." The 111-year-old hotel is now planning to remove all their electronic locks, and return to old-fashioned door locks with real keys. But they're going public to warn other hotels -- some of which they say have also already been hit by ransomware.
UPDATE: The hotel's managing director has clarified today that despite press reports, "We were hacked, but nobody was locked in or out" of their rooms.

Who thought it was a good idea for essential systems like this to be online in the first place?!
This is why the Internet of Things is such a horrible concept. Most things don't need to be online and connected to everything else, and the cost of trying to be trendy is huge increases in risks to the privacy, security and reliability of everyday items.
Closed networks do just fine for these kinds of systems, don't actually need to cost that much more, and have none of the vulnerabilities.
If you disagree, post your argument. (-1, Overrated) isn't your personal censorship tool for views you don't like.
Critical infrastructure DOESN'T NEED ACCESS TO A PUBLIC INTERNET.
Governments, utility providers, MILLITARIES! All of them have publicly accessible computers. WHY?
Welp folks, since we're not willing to use common sense in deploying our electronic systems to ensure their security and integrity, we're going to abandon digital and go back to mechanical.
With this challenge out of the way, we're looking at resolving the parking lot conundrum by bringing back horse buggies. To prevent our central heating and air from being hacked, we're uninstalling it and putting fireplaces and fans in all the rooms.
What was the name of the ransomware, what was the name of the company that designed the locks, what OS did the reservation system run on, what OS did the cash desk system run on?
"Unless this is all just a big publicity stunt to advertise their new door locks."
Yea, that's it, a hotel would try and drum up business by advertising that its electronic door locks can be compromised.
I can understand people being locked out of their rooms. But if they're being locked in they're in massive violation of fire safety laws.
Daily Mail? Seriously? Out of all the media that covered this story extensively over the past couple of days, you picked to link to the daily mail as the source? Also including the clickbait phrase of "paid thousands" to refer to 2 bitcoins? The only hope is that slashdot community does what it's best at: does not read the article.
"We were hacked, but nobody was locked in or out," said the hotel's Managing Director Christopher Brandstaetter. "For one day we were not able to make new keycards." "Since the locking system must work even in the event of power failure, the guests in the hotel almost did not notice the incident," the manager also added. "We simply could not issue new keycards because the computers were encrypted."
"First they came for the slanderers and i said nothing."
If, and yes, I mean "if", this were a key card only system then the lock doesn't need to communicate with the key making system at all. It just needs a token that increments with each next guest's card. When the token increments, the key cards from the prior guest stop working. When I worked at a hotel this is how the system worked. The key-making system was completely isolated. The desk person poked the room number on a key pad and the key programming box spit out a key. All it did was open that room's door.
The system in the article is what happens when you want to use your key card for all the other stuff in a hotel, like the restaurant, gift shop, etc, to be charged using the key. All the comments about key card systems not needing to be connected miss this detail. The hotel in question was almost certainly using an integrated billing-via-key card system, not just a key card system. The integrated system needs to communicate outside to approve credit cards, email a copy of your receipt, etc, etc, and thus the security weakness.
We have electronic locks at work, and they are on the Internet. They are VLAN'd and firewalled off but they are still on the Internet because the company that administers them is remote. You can argue we should do it our self and I'd agree, but that is the arrangement. However every single one can be overridden on the inside the the handle. The locking mechanism is just that it basically unlocks the door frame so you can push it open from the outside with the electronic lock. Inside, you can always use the handle to override.
The reason is, as you say, fire code. All our doors always open towards the outside, no matter what. Old lock and key doors are the same. You will find a door with a Medeco lock on the outside that can't be permanently unlocked, only turned to move the bolt, but on the inside ti is just a bar you push to open it up. No matter where you are in the building, you can always get out just by following the doors that will open manually with no key/code. The locks are for locking people out, not in.
