Lock Out: the Austrian Hotel That Was Hacked Four Times (bbc.com)

AmiMoJo shares a BBC report: Christoph Brandstatter is managing director of the four-star Seehotel, Jagerwirt, in Austria's Alps. His hotel's electronic door locks and other systems were hacked for ransom four times, between December 2016 and January 2017. "We got a ransomware mail which was hidden in a bill from Telekom Austria." His hotel's door keys became unusable after he clicked on a link to his bill. So was his hard drive. "Actually, as a small business you do not really think that anybody's interested in you for hacking, so we had no plan what to do," he recalls. He paid a ransom of two bitcoins, saying "at that time it was about $1,882." He has now installed firewalls and new antivirus software, and has trained his staff to recognise phishing emails that may seem genuine but actually contain malware. And he's moved back to traditional metal keys.

      You are right on this. The simple concept of attack surface is the issue here. Offline, it takes physical access to a reader (which can be done), or physical access to the hotel network or the admin PC. Online, anyone in the world can attack it. Offline, police are relatively excellent at finding traces of a physical intruder and nailing them, while online, unless the person is extremely sloppy or they ticked off someone with enough money to hunt them down, they won't get caught.

      Physical security devices should never be allowed on the Internet, period. Firmware updates should be signed, downloaded through a SD card, and updated via a manual basis, with a way to undo the update should it foul things up. If Compaq Deskpros and ProLiant machines in 1995 could do this, then machines made 20 years later can be made to be far more secure. I like the idea of a deadbolt that can tell if it is open or not... perhaps with the ability to lock from remote (but never unlock), but even that can be a hazard, since a would-be thief who gets access can just set a poll and alert him/her when the door is unlocked for a certain period of time.

      I do agree for a hotel that keycards are a step above physical keying systems, but there can be a balance. Assa-Abloy has Abloy PROTEC2 locks with part of it being electronic (CLIQ). That way, there is both physical resistance to picking, as well as the ability to block a key from being used.

      Both mechanical and electronic locks have good and bad points. A good mechanical system, if done by a locksmith who knows what they are doing with software to allow for proper keying, a lock mechanism that is reasonably high security [1] and allows a ton different keys, and quick responsiveness (if a guest leaves with a key, change the lock.) If this is done, the lock mechanism can be simple, yet very secure. I remember one place where when you closed the door, it threw the deadbolt, which was easily opened from the inside by the door knob. This lock couldn't be opened with a credit card.

      Electronic locks may be easier to "rekey", but instead of picking, there is bypassing, and there tend to be as many ways to bypass a certain model of electronic lock (if not more) as there are for mechanical locks. For a smaller place that can't really have a locksmith on duty, electronic locks (with everything kept offline) are arguably the best option, but for a five star place, maybe having a high security key to hand to a guest would be a better option.

      [1]: Most US door locks are shit. Five tumblers, maybe six.

They maybe learned a thing or two about using them, they might even have managed to navigate an ECDL course which is basically a glorified way of saying "I can turn on a computer without it instantly exploding", but their expertise and actual training is in something completely different. Many of them actually do not like computers AT ALL. They much prefer dealing with people, else they would not have chosen that occupation.

    These people are now chronically understaffed, overworked and stressed. They're supposed to greet people, hand them their keys, do bills, handle the phone and of course email. And no, simply hiring more people isn't possible, there are no more people you could hire. We're talking about a highly seasonal business where there are either too many or too few people available, hence no more want to go into the profession while at the same time during season you can't get anyone. Not even for obscene amounts of money.

    On top of all this, you're dealing with ... how do I put this nicely... a rather mafia-like system in place that keeps the number of companies that could actually offer solutions low. Most hotel software is crap. And most hotels would gladly choose something else, if they could. But for some odd reason those systems that are offered can be offered surprisingly cheap (it MIGHT have to do with some semi-public agencies (an Austrian concept, don't ask) that curiously prefer to fund and subsidize those products), while you would certainly not qualify for such subsidies. The cynic in me would add "at least 'til you find the right politician to pay the kickback to", but no, there is no corruption in Europe. None at all. Maybe in Italy, Spain and Greece, but certainly not in the "good" states in central Europe.

    So, now you have the basics in, let the rest sink in too. Like a fluctuation that's CRAZY. Average tenure of your workers is measured in weeks. Months if you're lucky. Training them is money you throw into the chimney, for the benefit of whoever they work for next. So if you think that you could raise awareness and give your workers an idea what to look for, ponder whether you'll still have that receptionist after the season is over. There is zero security awareness among your workers.

    Then the fact that you pretty much HAVE TO open every email you get, and that crappy spelling is something that doesn't faze you anymore because you're dealing with people from all over the planet, many of them wanting to boast just how well they speak your language when they actually don't. Some of them required to actually send you attachments for legal reasons, with the oddest formats you will ever encounter. In other words, the chance that some viewer for an esoteric format is installed and WAY out of date because nobody had a minute of time to update it in the past 3 months is likely.

    The situation is not easy and I was actually involved in a similar case where pretty much every solution we came up with ended up being shot down for one of these reasons (and some more, but I don't want to bore you more than necessary).
