Ransomware Infects a Hotel's Key System (dailymail.co.uk) 203

Posted by EditorDavid from the room-service-not-available dept.
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.

    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.

        Agree, and it's because the hotel thinks the bottom line is accounts payable/accounts receivable where revenue exceeds expenses.

        Loss-prevention is a cost of doing business.

        Hotels can pay for that up front, or pay for it later.

        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.

        The problem wasn't the electronic key system. The problem was the hotel stupidly made their electronic key system (or at least the server) accessible from the public Internet.

        I used to work at a hotel and helped select one of these key card systems for purchase (I wasn't around for the installation). You're supposed to keep it on a separate and isolated network specifically to prevent problems like this. The system is completely self-contained and internal. Nothing else needs access to it, and you don't need to have access to anything else from it. The person using the key card server doesn't need to be able to browse their Facebook page on it. The only data being entered into it should be the front desk staff keying in the guest's name and dates of stay so that a new key card can be generated and the lock for that room reprogrammed.

        Physical keys at hotels were/are a huge problem because anyone can make a copy of the key. Theoretically a guest could make a copy to access the room at a later date. But more commonly, one of the maids (who have master keys so they can access all rooms) makes a copy, gives it to someone else, who then goes into the rooms and steals stuff when the maid is off-duty (so as not to arouse suspicion as to who copied their key). Changing the locks is expensive and doesn't help, because the corrupt maid simply makes a copy of the new key. It's cheaper to make a copy of a physical key than it is to change all the physical locks. OTOH, it's cheaper to change all the electronic lock keys than it is to make a copy of the newer RFID key cards. Switching back to physical keys is huge step backwards in security.

        • Also, a proper backup policy could completely eliminate this failure mode. Ironically you could *more easily* secure this with *more* internet integration. Have the backups be incremental and off-site. Setup the off-site service to keep backups for 7 days no matter what. If at any point someone hacks your system, physically insert a "RESET" DVD. Format *everything* back to factory defaults. Load the latest good database and you should be back in business in half an hour.

      "Common sense" is not very "common" at all when it comes to electronic systems, and it's even less common when it comes to computer security. The vast majority of people -- even those running big businesses -- simply have no clue how computers or networks or whatever work in any detail. So how can they have "common sense" about them?

      And I think it's only getting worse. Interfaces on computers and electronics keep getting "simpler" with more information hidden from the end user. These changes are often pushed by companies that have a strong interest in keeping their users ignorant of things like security, because it allows them to continuously steal their users' data and information. So, a normal "user" who encounters technology on an everyday basis is going to get dumber about security if trends of the past couple decades continue. "Common sense" about such things will get even more rare.

      Seriously -- obviously an air-gapped system is a easy solution here, but do you realize that most people don't even understand what that means? I've had lots of conversations with people who still can't even tell the difference between local applications/data and the internet... and cloud interactions are further blurring such distinctions all the time, so there's little benefit for most people in trying to understand such distinctions.

Not that anyone with some common sense wouldn't know that all these idiotic new fangled IoT devices will end up having their own problems with vulnerabilities and hacking, we basically have proof every single week or day on how easily those can be defeated... yet we keep seeing big companies investing on stuff like that as if nothing was happening.

    Save yourselves the headache guys, and do not buy any IoT devices whatsoever in which usefulness do not trample security concerns and overall pro

  • What kind of fucking stupid design is that where that is even physically possible? It should run afoul of absolutely every kind of fire regulation imaginable that a door lock can even *POSSIBLY* lock a person in their unit.

    The mechanism to unlatch the door should be *PHYSICALLY* tied to the turning of the handle or knob on the inside of the unit such that the only way to potentially lock someone in would be to physically damage the latch first... either by welding it into position or otherwise gutting the innards so that it did not work.

    • heck as a fail safe they should have the hinges set with pins that can be yanked out with Pliers (sitting next to the Gideon Bible in the top dresser drawer)

    • It's not a stupid design at all, just a stupid Daily Mail reporter.

  • I would never trust anything I own and absolutely need to work to an electronic lock. Not that I'm a luddite ... far from it ... but because I know what can go wrong, and in some circumstances absolutely nothing can be allowed to go wrong. So no electronic locks on my home's entry doors, and no home safes with electronic locks (includes gun safes).

    Hotels ... I can see huge advantages for a hotel to have electronic locks on rented rooms. They will also have staff who can defeat said locks if need be. Downsid

    • The more I learn about physical locks, the less I'm convinced they are up to the job. I don't think locks should be all electric, but a lot of locks that use physical keys are laughably insecure.

  • In what world is it considered a sane design decision that it is possible for guests to be locked in a hotel room? It seems like the sort of thing that should be a fire code violation at least.

    According to this article, it was not the locks that were encrypted [bleepingcomputer.com]. The computers they used to make new card keys got encrypted. I'd bet that it was just a bog-standard Windows box with a dongle attached, maybe running Windows XP if the drivers couldn't be updated. Here is a quote from the hotel manager:

    "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."

    • I was seriously wondering how people could get locked in their rooms. I mean that is such a massive fire code violation and commercial buildings care, a lot, about fire code because you can be sued in to oblivion.

      Incorrect clickbait headline. Now that makes much more sense :D.

  • I call BS on this one. Locking guests out of their rooms, sure. Locking guests into their rooms? Uh no. Basic fire code requires that all electronic locks always allow egress, regardless of their lock state or powered/unpowered. Basically, the mechanical locking mechanism can always be opened from the inside, regardless of how the electronic locks are hacked or malfunction.

    • Read the quote right above your post. No one got locked in... the room-card-writing computer got hit with ransomware. That's all.

      The summary is almost totally wrong, in other words.

  • All these insecure systems need to be attacked and exposed for the garbage that they are. Everyone that knows about computer systems or security has been screaming that IoT systems are bad and are not to be trusted. Despite all of this, plenty of fools in management went ahead because they are arrogant pricks who don't give a shit about what other people think. At this point, getting hit with ransomware is your wage, as in, you have gone out of your way to earn it.

    You reap what you sow.

    Yeesh. If you decide to not go back to physical keys, at least consider these next time:

    1) Don't connect your door/key system to the Internet, at all.
    2) Isolate the machine on your network to just the needed functionality.
    3) Isolate the machine physically- nobody but specialized staff should have physical access.
    4) Restrict root/admin access to the machine.
    5) If possible, get a system not run by any MS-Windows machines.
    6) Make, test, and retain good, redundant, and incremental backups.
    7) Perhaps hire or contract with I.T. staff that can set up and maintain your systems properly.

    Computer systems are not like ice makers or or other appliances at a hotel. They need to be designed, setup, and maintained properly to work well. And, unfortunately, they are rarely a one-time expense. This, more than anything, is what gets companies into trouble. These types of failures being reported are more about management failure than failures of technology.

  • Rubbish. I've never stayed in a hotel with key cards where the inside handle didn't override/bypass the lock.
